Cars are a very important part of this modern world because they give luxury and comfort. Even
though they are comfortable, some problems always keep arising on the safety side. After a lot of research they
rectified certain problems using air bags, auto parking, turbo charger, pedal shift…, etc.
And now we are going to discuss about one such problem that arises on the safety side. An unsuspected
accident occurs when people smash their fingers in between the car doors. Due to this kind of accident around
120,000 people are injured every year. But this was not taken as a very major safety concern for the customer.
To avoid this kind accident due to car doors, we are introducing “SAFETY DOOR LOCK SYSTEM”
with the help of “HYDRAULIC PISTON AND IR SENSORS”.
The major working process of the “SAFETY DOOR LOCK SYSTEM”is, when a person places his/her
hand or fingers in the gap between the door and the outer panel, at the time when the closing action of the door
takes place, the Sensors start to transmit the Infra Red Rays to the Receivers at the
other end, and so even if someone closes the door without anybody‟s knowledge the hydraulic piston will
automatically come out and stop the door from closing and prevent the person from the unsuspected accident
and minor injuries by the car door and ensure maximum safety to the customer.
Extrusion can be defined as the process of subjecting a material to compression so that it is forced to
flow through an opening of a die and takes the shape of the hole. Multi-hole extrusion is the process of
extruding the products through a die having more than one hole. Multi-hole extrusion increases the production
rate and reduces the cost of production. In this study the ram force has calculated experimentally for single hole
and multi-hole extrusion. The comparison of ram forces between the single hole and multi-hole extrusion
provides the inverse relation between the numbers of holes in a die and ram force. The experimental lengths of
the extruded products through the various holes of multi-hole die are different. It indicates that the flow pattern
is dependent on the material behavior. The micro-hardness test has done for the extruded products of lead
through multi-hole die. It is observed that the hardness of the extruded lead products from the central hole is
found to be more than that of the products extruded from other holes. The study suggests that multi-hole
extrusion can be used for obtaining the extruded products of lead with varying hardness. The micro-structure
study has done for the lead material before and after extrusion. It is observed that the size of grains of lead
material after extrusion is smaller than the original lead.
Analysis of Agile and Multi-Agent Based Process Scheduling Modelirjes
As an answer of long growing frustration of waterfall Software development life cycle concepts,
agile software development concept was evolved in 90’s. The most popular agile methodologies is the Extreme
Programming (XP). Most software companies nowadays aim to produce efficient, flexible and valuable
Software in short time period with minimal costs, and within unstable, changing environments. This complex
problem can be modeled as a multi-agent based system, where agents negotiate resources. Agents can be used to
represent projects and resources. Crucial for the multi-agent based system in project scheduling model, is the
availability of an effective algorithm for prioritizing and scheduling of task. To evaluate the models, simulations
were carried out with real life and several generated data sets. The developed model (Multi-agent based System)
provides an optimized and flexible agile process scheduling and reduces overheads in the software process as it
responds quickly to changing requirements without excessive work in project scheduling.
Effects of Cutting Tool Parameters on Surface Roughnessirjes
This paper presents of the influence on surface roughness of Co28Cr6Mo medical alloy machined
on a CNC lathe based on cutting parameters (rotational speed, feed rate, depth of cut and nose radius).The
influences of cutting parameters have been presented in graphical form for understanding. To achieve the
minimum surface roughness, the optimum values obtained for rpm, feed rate, depth of cut and nose radius were
respectively, 318 rpm, 0,1 mm/rev, 0,7 mm and 0,8 mm. Maximum surface roughness has been revealed the
values obtained for rpm, feed rate, depth of cut and nose radius were respectively, 318 rpm, 0,25 mm/rev, 0,9
mm and 0,4 mm.
Possible limits of accuracy in measurement of fundamental physical constantsirjes
The measurement uncertainties of Fundamental Physical Constants should take into account all
possible and most influencing factors. One from them is the finiteness of the model that causes the existence of
a-priori error. The proposed formula for calculation of this error provides a comparison of its value with the
actual experimental measurement error that cannot be done an arbitrarily small. According to the suggested
approach, the error of the researched Fundamental Physical Constant, measured in conventional field studies,
will always be higher than the error caused by the finite number of dimensional recorded variables of physicalmathematical
models. Examples of practical application of the considered concept for measurement of fine
structure constant, speed of light and Newtonian constant of gravitation are discussed.
Performance Comparison of Energy Detection Based Spectrum Sensing for Cogniti...irjes
With the rapid deployment of new wireless devices and applications, the last decade has witnessed a growing
demand for wireless radio spectrum. However, the policy of fixed spectrum assignment produces a bottleneck for more
efficient spectrum utilization, such that a great portion of the licensed spectrum is severely under-utilized. So the concept of
cognitive radio was introduced to address this issue.The inefficient usage of the limited spectrum necessitates the
development of dynamic spectrum access techniques, where users who have no spectrum licenses, also known as secondary
users, are allowed to use the temporarily unused licensed spectrum. For this purpose we have to know the presence or
absence of primary users for spectrum usage. So spectrums sensing is one of the major requirements of cognitive radio.Many
spectrum sensing techniques have been developed to sense the presence or absence of a licensed user. This paper evaluates
the performance of the energy detection based spectrum sensing technique in noisy and fading environments.The
performance of the energy detection technique will be evaluated by use of Receiver Operating Characteristics (ROC) curves
over additive white Gaussian noise (AWGN) and fading channels.
Comparative Study of Pre-Engineered and Conventional Steel Frames for Differe...irjes
In this paper, the conventional steel frames having triangular Pratt truss as a roofing system of 60 m
length, span 30m and varying bay spacing 4m, 5m and 6m respectively having eaves level for all the portals is at
10m and the EOT crane is supported at the height of 8m from ground level and pre-engineered steel frames of
same dimensions are analyzed and designed for wind zones (wind zone 2, wind zone 3, wind zone 4 and wind
zone 5) by using STAAD Pro V8i. The study deals with the comparative study of both conventional and preengineered
with respect to the amount of structural steel required, reduction in dead load of the structure.
Flip bifurcation and chaos control in discrete-time Prey-predator model irjes
The dynamics of discrete-time prey-predator model are investigated. The result indicates that the
model undergo a flip bifurcation which found by using center manifold theorem and bifurcation theory.
Numerical simulation not only illustrate our results, but also exhibit the complex dynamic behavior, such as the
periodic doubling in period-2, -4 -8, quasi- periodic orbits and chaotic set. Finally, the feedback control method
is used to stabilize chaotic orbits at an unstable interior point.
Energy Awareness and the Role of “Critical Mass” In Smart Citiesirjes
A Smart City could be depicted as a place, logical and physical, in which a crowd of heterogeneous
entities is related in time and space through different types of interactions. Any type of entity, whether it is a
device or a person, clustered in communities, becomes a source of context-based data.
Energy awareness is able to drive the process of bringing our society to limit energy waste and to optimize
usage of available resources, causing a strong environmental and social impact. Then, following social network
analysis methodologies related to the dynamics of complex systems, it is possible to find out, emergent and
sometimes hidden new habits of electricity usage. Through an initial Critical Mass, involving a multitude of
consumers, each related to more contexts, we evaluate the triggering and spreading of a collective attitude. To
this aim, in this paper, we propose a novel analytical model defining a new concept of critical mass, which
includes centrality measures both in a single layer and in a multilayer social network.
A Firefly Algorithm for Optimizing Spur Gear Parameters Under Non-Lubricated ...irjes
Firefly algorithm is one of the emerging evolutionary approaches for complex and non-linear
optimization problems. It is inspired by natural firefly‟s behavior such as movement of fireflies based on
brightness and by overcoming the constraints such as light absorption, obstacles, distance, etc. In this research,
firefly‟s movement had been simulated computationally to identify the best parameters for spur gear pair by
considering the design and manufacturing constraints. The proposed algorithm was tested with the traditional
design parameters and found the results are at par in less computational time by satisfying the constraints.
The Effect of Orientation of Vortex Generators on Aerodynamic Drag Reduction ...irjes
One of the main reasons for the aerodynamic drag in automotive vehicles is the flow separation
near the vehicle’s rear end. To delay this flow separation, vortex generators are used in recent vehicles. The
vortex generators are commonly used in aircrafts to prevent flow separation. Even though vortex generators
themselves create drag, but they also reduce drag by delaying flow separation at downstream. The overall effect
of vortex generators is more beneficial and proved by experimentation. The effect depends on the shape,size and
orientation of vortex generators. Hence optimized shape with proper orientation is essential for getting better
results.This paper presents the effect of vortex generators at different orientation to the flow field and the
mechanism by which these effects takes place.
An Assessment of The Relationship Between The Availability of Financial Resou...irjes
The availability of financial resources is an important element in impacting the success of a planning
process for an effective physical planning. The extent to which however, they are articulated in the process
remained elusive both in scholarly and public discourse. The objective of this study wastherefore, to examine
the extent to which financial resources affect physical planning. In doing so, the study examinedwhether
financial resources were adequate or not to facilitate planning processes in Paidha. According to the study
findings,budget prioritization and ceilings are still a challenge in Paidha Town Council. This is partly due
limited level of knowledge of physical planning among the officials of Paidha Town Council. As a result, there
were no dedicated budget line for routine inspection of physical development plan compliance and enforcement
tools in Paidha. In conclusion, in addressing uncoordinated patterns of physical development that characterize
Uganda‟s urban centres, a critical starting point ought to be the analysis of physical planning process. The
research of this kind is not only significant to other emerging urban centres facing poor a road network,
mushrooming informal settlements and poor social services including poor pattern of residential and commercial
developments but also to all institutions that are involved in planning these towns. Knowing the extent of need
for financial influences in planning may assist local authorities to take the processes of planning seriously which
will help enhance the sustainable development of emerging urban centres including Paidha.
The Choice of Antenatal Care and Delivery Place in Surabaya (Based on Prefere...irjes
- Person's desire to do a pregnancy examination is determined by the service place that suits the tastes
and facilities owned by it. Until now, the utilization of antenatal care by pregnant women is still low (Mardiana,
2014). The purpose of the study is to analyze factors affecting the utilization of antenatal care and delivery place
in Surabaya city based on the preferences and choice theory.
Type of survey research is cross sectional approach, the population is mothers who have children aged 1-
12 months in Surabaya. The large sample of 250 mothers who have children aged 1-12 months in 2013 is taken
by simple random sampling technique. Variables of the research are the preference elements and steps, choice
elements and steps, utilization of antenatal care and delivery place. Data were collected through questionnaires
and secondary data were then analyzed with descriptive statistics in the form of a frequency distribution, shown
by the schematic diagram.
The result showed that the preference elements and steps showed almost half (42.9%) desire to give birth
in a health care because of information got from someone else, while the choice element and step shows the
bulk (57.1%) of the criteria of delivery place chosen is a safe, comfortable and cheap delivery place, the labor
place which is the main choice most (57.1%) is cheap, comfortable, close.
Conclusion of the research based on the preferences and choice theory can be found three (3) new
theories, they are preferences become choice, preferences do not become choice, choice is preceded by
preferences

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

purpose of data transfer. VNC1L chip runs on different application oriented firmwares, out of which VDFC
firmware is used to connect two BOMS devices to VDIP2 module, thus it acts as a USB host controller. This
module is controlled using microcontroller over serial UART communication. Thus microcontroller acts as a
monitor which is used to command this module in order to perform desired task. In this way, it is possible
eliminate the use of bulky desktop for the purpose for data transfer between two pen drives using
microcontroller.

I. INTRODUCTION
The popularity of Universal Serial Bus (USB) storage devices is an indication of the computer user's
need for a fast, large capacity and easily accessible system for data storage and transfer. As the development of
USB enabled peripherals increases, the USB has rapidly become a de facto standard in communication with the
Personal Computer and has led to new technologies for interfacing memory devices. These memory/storage
devices connect to the USB ports and appear as removable storage device in personal computers, the most
popular of which is the USB Flash Drive. The disadvantage of USB storage devices is that being a peripheral
device, it needs a host, usually a Computer to initiate and mediate communications between two USB storage
devices or other peripheral devices.
As a solution to the USB Flash Drive disadvantage, the project aims to develop a device that allows file
transfers between two USB memory devices without the need for a personal Computer. This report discusses the
current implementation of VDIP2 module having VNC1L chip incorporated on it. Module is connectable
because of its compatibility with standard 40pin DIP socket.
VNC1L contains host controller, which means, that it can manage all USB communication without any
personal computer. To control the function of VNC1L are used commands, which are sent via UART, SPI or
FIFO interface from the microcontroller. These commands can be sent like ASCII characters (IPA mode) or like
hex code values (IPH mode). There can be chosen Shortened Command Set (SCS) or for more functionality
Extended Command Set (ECS).
VNC1L is very powerful chip and it can be used in many different ways. This work shows one small
part of the possible usage.
II. HARDWARE DESCRIPTION
The VNC1L chip on VDIP2 module is used as a USB host controller. The detailed description about
USB hardware can be found in [1] [2] [3]. It has two USB ports, one of which acts as source and the other acts
as a target which can be configured during programming. The USB flash drives are connected to these ports. A
monitor or ATMEGA16 Microcontroller can be used to command VDIP2 module. Here, monitor acts as a
master and VNC1L as a slave. The commands are sent to the module by the master via communication channel.
The mode of communication can be chosen from UART, SPI or FIFO. UART is used here as a mode of
communication between monitor and the module. Fig. I shows the block diagram.

2.1 VDIP2 Module
The VDIP2 module is an MCU to embedded USB host controller development module for the VNC1L
IC device. The VDIP2 is supplied on a PCB designed to fit into a 40 pin DIP socket, and provides access to the
UART, parallel FIFO, and SPI interface pins on the VNC1L device, via its AD and AC bus pins. All other
Vinculum I/O pins are also accessible. Not only it is ideal for developing and rapid prototyping of VNC1L
designs, but also an attractive quantity discount structure makes this module suitable for incorporation into low
and medium volume finished product designs [4].

2.2 VNC1L Chip
The VNC1L is the first of FTDI‟s Vinculum family of Embedded USB host controller integrated
circuit devices. Vinculum can also encapsulate certain USB device classes handling the USB Host Interface and
data transfer functions using the in-built MCU and embedded Flash memory. When interfacing to mass storage
devices, such as USB Flash drives, Vinculum transparently handles the FAT File Structure using a simple to
implement command set. Vinculum provides a cost effective solution for introducing USB host capability into
products that previously did not have the hardware resources to do so. The VNC1L has a Combined Interface
which interfaces a controlling application with the Command Monitor. The combined interfaces are UART,
Parallel FIFO and SPI. The VNC1L chip features an integrated 8/32-bit MCU and 64k embedded Flash
memory. Not only does the chip handle data transfer functions on two USB Host/Client interfaces; it
encapsulates several USB device classes as well. One doesn't have to worry about writing firmware to
implement those functions. When interfacing to mass storage devices such as USB Flash drives, the VNC1L
transparently handles the FAT file structure communicating via UART, SPI or parallel FIFO interfaces via a
simple-to-implement command set. The VNC1L device features two USB ports which can be individually
configured by firmware as Host or Slave (client) ports. VNC1L brings cost-effective USB Host capability to
products that previously did not have the hardware resources available [5].

2.3 ATMEGA 16
ATmega16 is an 8-bit high performance microcontroller of Atmel’s Mega AVR family with low power
consumption. Atmega16 is based on enhanced RISC (Reduced Instruction Set Computing) architecture with 131
powerful instructions. Most of the instructions execute in one machine cycle. Atmega16 can work on a
maximum frequency of 16MHz. ATmega16 has 16 KB programmable flash memory, static RAM of 1 KB and
EEPROM of 512 Bytes. The endurance cycle of flash memory and EEPROM is 10,000 and 100,000,
respectively. ATmega16 is a 40 pin microcontroller. There are 32 I/O (input/output) lines which are divided into
four 8-bit ports designated as PORTA, PORTB, PORTC and PORTD. It also has various in-built peripherals
like USART, ADC, Analog Comparator, SPI, JTAG etc. Each I/O pin has an alternative task related to in-built
peripherals. The following table shows the pin description of ATmega16 [6].

III. SCHEMATIC
Figure V: Schematic Diagram
Fig. V shows schematic of the project [7] [8]. It is basically the UART connection form the monitor to the
host USB controller module VDIP2. The pins which serve as a UART on the VDIP2 are AD3, AD2, AD1
and AD0. Table I shows the pins and their respective functions.

Table I: VDIP2 Module Pin Functions
These pins are connected to the RS232 adapter via MAX232 IC [9]. The MAX232 is an IC that
converts signals from an RS232 serial port to signals suitable for use in TTL compatible digital logic circuits.
The MAX232 is a dual driver/receiver and typically converts the RX, TX, CTS and RTS signals. The VDIP2
module also has two jumpers J3 and J4 which needs to be configured for the use of the 4 signals as a UART.
The middle pins of both J3 and J4 are connected to AC5 and AC6 pins of VDIP2 respectively. If we want to use
the pins as UART then the jumpers need to be connected to either VCC (5V) or GND. The jumpers are
connected to VCC as shown in the above circuit diagram. The 5V supply is provided to the MAX232 IC and
VDIP2 module. Ground of all the three VDIP2, MAX232 and RS232 are shorted. The 5V supply for the VDIP2
is connected to pin no. 9 and Ground is connected at pin no. 15. The capacitors C1, C2, C3 and C4 are used with
MAX 232 to set the direction of the internal buffers. All the capacitors are of 0.1 uF. The capacitors are
connected as shown in table II (a).

IV. SOFTWARE DESCRIPTION
4.1 HyperTerminal
HyperTerminal (also known as HyperTerm) is a communications and terminal emulation program
HyperTerminal can be used to set up a dial-up connection to another computer through the
internal modem using Telnet or to access a bulletin board service (BBS) in another computer. It can also be used
to set up a connection for data transfer between two computers (such as your desktop computer and a portable
computer) using the serial ports and for serial-port control of external devices or systems such as scientific
instruments, robots, or radio communications stations. HyperTerminal can also be used as a troubleshooting tool
when setting up and using a modem. You can send commands through HyperTerminal to make sure that your
modem is connected properly. We can use HyperTerminal mainly for debugging purpose as it displays all the
process messages and error messages on screen [10].

4.2 WINAVR AVRDUDE
AVR Downloader Uploader is a program for downloading and uploading the on-chip memories of
Atmel’s AVR microcontrollers. It can program the Flash and EEPROM, and where supported by the serial
programming protocol, it can program fuse and lock bits. AVRDUDE also supplies a direct instruction mode
allowing one to issue any programming instruction to the AVR chip regardless of whether AVRDUDE
implements that specific feature of a particular chip. AVRDUDE can be used effectively via the command line

to read or write all chip memory types (EEPROM, flash, fuse bits and lock bits, signature bytes) or via an
interactive (terminal) mode. Using AVRDUDE from the command line works well for programming the entire
memory of the chip from the contents of a file, while interactive mode is useful for exploring memory contents,
modifying individual bytes of EEPROM, programming fuse/lock bits, etc. Programmers Notepad is an Open
Source editor with some IDE features. It contains the Open Source Scintilla editor component as the basis for its
editor. It can be used to write/compile code and generate/burn HEX file. MFile is an automatic makefile
generator for AVR GCC written in Tcl/Tk and can run on various platforms including Windows, FreeBSD,
Linux, etc. This utility quickly generate a makefile on some simple menu input. MFile for the Windows
platform uses the WinAVR Makefile Template for its template.
4.3 VNC1L FIRMWARE
The VNC1L is shipped as a blank device. Initial in-circuit programming (using the downloaded .rom
firmware file) can only be done via the UART interface. When upgrading VNC1L in-situ, then the device can
be programmed via the UART interface (.rom file). Alternatively, it can be upgraded via a USB Flash disk using
a file called “ftrfb.ftd”. Both file types can be downloaded from the FTDI website. Any firmware downloaded
from the FTDI website should be changed to match this filename. VNC1L devices can also be programmed
before being assembled in a system using the VPROG1 VNC1L standalone programmer.
V. APPLICATIONS
VDAP firmware is the most general purpose and supports most devices on Port 1 and Port 2. The
VMSC and VCDC builds are based on the VDAP code and so provide similar functionality. VDPS firmware is
required if the VNC1L is to be used as both a host and a slave device. VDIF should only be used in exceptional
applications where the monitor must be accessible on USB Port 1. VNC1L can be used to provide USB Host
functionality to a microcontroller, which is a typical application for VDAP firmware. This will have the monitor
port on the combined interface allowing BOMS devices to be connected to Port 2 and USB Slave Peripherals to
Port 1. The VNC1L is used to connect two BOMS devices to the VDIP2 module using the VDFC Firmware.
The monitor port allows access to either disk and the facility to copy between the disks. Selected
communication class devices can be connected to the Vinculum VNC1L to provide modem-like functionality to
microcontrollers. The CDC device must support the sub-class of Abstract Control Model and have compatible
bulk endpoints. The CDC firmware requires that call management information can be sent or received over the
Data Class interface. When a CDC device is connected to either USB port on the Vinculum VNC1L it is
automatically connected in Data Mode to the Monitor interface. There are separate output pins for modem
control (RI#, DCD#) used by the VCDC firmware while the connection is active. This device can be used for
fast USB to USB file transfer in offices or other places without the help of mediators such as Personal Computer
to handle such transfers. Also this device can be made capable to transfer files based on the user requirements.
VI. CONCLUSION
This paper discusses the hardware and software description along with the schematic. The paper puts
light on such a device which has great application since it eliminates the use of bulky computer for the purpose
of transferring data. The goal of transferring data from one flash drive to another can be successfully achieved
by devising a device which works on the principle described in this paper. With the given constraints and
assumptions, UART can be selected as a mode of communication between the ATMEGA 16 (monitor) and
VDIP2 module (VNC1L). The problems faced now will leave future work on the project with great possibilities.
Further research on this paper can lead to the solution for the problems faced.
VII. FUTURE PLANS
VMSC firmware is similar to VDAP firmware but introduces new commands to allow playback
through an MP3 decoder chip. Data is sent to a VLSI VS1003 MP3 decoder over an SPI bus and control of
playback is performed by a microcontroller. Current track filename is displayed when playback of a track is
started. The elapsed time of the current track is displayed every second. VMSC firmware relies on hardware
connections to devices found on a VMUSIC1 or VMUSIC2 module and will therefore not function with other
modules. The VMUSIC1 and VMUSIC2 modules do not include USB Port 1. This device can hence be used to
play songs stored in your Flash drive or iPhone on speakers. Also since it’s a low power device it can work on
batteries. Firmware named VDPS can be used to interface the flash drive to various slow devices like printer,
scanner or fax machine. It can be of immense use for shops which are specifically opened for getting printouts
or for scanning images or for faxing documents.
