The document discusses various design ideas for a staircase lift to help disabled persons move between floors. The ideas considered and ruled out include a rolling ramp, staircase climbing wheelchair, low-cost stair climbing wheelchair, and an IIT student project called Vardaan. Reasons for ruling out the ideas included occupying too much space, needing an assistant, slow speed interrupting stair flow, and safety risks from electrical or mechanical failures. The document aims to select the most suitable design approach for a safe and effective staircase lift.
Traditional manual wheelchairs require considerable use and control of both arms for operation, thus adaptations are required for individuals with asymmetrical use of their arms. Building upon previous projects, the goal of this project was to create an accessory, to be installed on a standard wheelchair, which would allow full control of the wheelchair with only one arm/hand while addressing areas lacking in commercial products and previous designs, such as manufacture ability, attendant control, user comfort and ergonomics. After preliminary testing and analysis of three one-arm propulsion designs, the project team developed a design for a removable, lever-operated accessory which could be adapted to fit a range of the most popular standard wheelchair models. The propulsion system, connected to the main lever by a coupler link, consists of a dual gear-pawl assembly in which the desired direction of motion is chosen by moving a shifter to engage one of the two gears press-fit around clutches, each of which allows motion in only one direction, either forward or reverse. By including a neutral pawl position in which neither clutch is engaged, this design allows an attendant to propel and control the chair.

Abstract: The design and fabrication of 360 degree wheel rotation vehicle using DC motor and steering is done to reduce time to turn from one direction to other direction. This vehicle can move in all direction at a same position by used of steering, sprocket, DC motor, bearing and chain drive. Main function of this vehicle is easy to move from one direction to other direction. Modern development and economical progression of Indian society resulted in increase of people on railway platform, increase of vehicle on the road, due to space constraints, in hospital is major problem of the country. Present study aims for development of a system to reduce the turning radius of vehicle.
1. Designed a Remote Controlled Luggage Carrier which can withstand up to 40 kg (88lb) load.
2. The design was tested on ANSYS to validate its safety for practical loading scenarios.
Hyperloop: Design, Analysis & Optimization of ChassisSaiifi Haider
This presentation aims to understand the design, analysis and optimization of the Hyperloop chassis structure , which I gained during the Hyperloop Pod Building Competition organized by SpaceX. To reduce the aerodynamic drag, Hyperloop uses a partially evacuated tube, for running the pod. The design of the structure of hyperloop pod chassis is very critical due its high speed, vibrations induced due to it and critical dynamic conditions. Also, in today's world of mass production, we cannot keep the factor of safety unnecessarily greater than needed. Also, while maintaining the safety we also must consider the material costing. it is very necessary to analyses for stresses and accordingly to optimize it. Hyperloop is a proposed mode of passenger and freight transportation that propels a capsule-like vehicle through a near-vacuum tube at more than airline speed. The pods would accelerate using a linear electric motor and glide above their track using passive magnetic levitation or air bearings. Hyperloop consists of a low-pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift. Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length. It quickly becomes apparent just how dramatically the Hyperloop could change transportation, road congestion and minimize the carbon footprint globally. With the Hyperloop, extremely fast, inexpensive intercity travel would be widely accessible.

Water billing management system project report.pdfKamal Acharya
Our project entitled “Water Billing Management System” aims is to generate Water bill with all the charges and penalty. Manual system that is employed is extremely laborious and quite inadequate. It only makes the process more difficult and hard.
The aim of our project is to develop a system that is meant to partially computerize the work performed in the Water Board like generating monthly Water bill, record of consuming unit of water, store record of the customer and previous unpaid record.
We used HTML/PHP as front end and MYSQL as back end for developing our project. HTML is primarily a visual design environment. We can create a android application by designing the form and that make up the user interface. Adding android application code to the form and the objects such as buttons and text boxes on them and adding any required support code in additional modular.
MySQL is free open source database that facilitates the effective management of the databases by connecting them to the software. It is a stable ,reliable and the powerful solution with the advanced features and advantages which are as follows: Data Security.MySQL is free open source database that facilitates the effective management of the databases by connecting them to the software.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CW RADAR, FMCW RADAR, FMCW ALTIMETER, AND THEIR PARAMETERSveerababupersonal22
It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.

•The wheel chair lift is new invention for transporting a disabled
person between floors. The driving mechanism for this stair lift
includes one guide rail parallel to a stairway, a moveable carrier
frame suspended from the guide rails has a platform to carry
disabled person in wheel chair.
•The suspended carrier frame is driven by pinion and moves over
the rack fixed on the banister. The pinion was driven by the electric
motor.
•The driving mechanism used in this stair lift has feasibility to
implement in real time due to smooth motion, less cost and highly
reliable. It has possibility to make movement on turning stair ways
•The stair lift device uses a rail on stairways for lifting and
lowering one disabled person. The driving mechanism includes
carriage mountable to the rail, rail comprises a track portion and a
structural portion.
