The three documents discuss sensor technologies and applications. The first discusses using graphene for chemical, electrochemical, magnetic, electric, optical, mass and strain sensors due to its remarkable electronic and mechanical properties. The second describes tactile sensors using fiber Bragg grating and microbending optical fiber sensors to detect external forces. The third proposes extending the Low Level Reader Protocol finite state machine to model RFID systems and identify potential failures for testing and diagnosis.

1. SENSOR TECHNOLOGY
Graphene Sensors
Abstract:
This paper reviews the potential of graphene as a material for fabricating various types
of sensors. Graphene is a monolayer of carbon atoms which exhibits some remarkable
electronic and mechanical properties and many of these properties lend themselves
to sensor applications. The review attempts to be comprehensive in sensor types covering
chemical and electrochemical sensors, magnetic and electric field sensors,
optical sensors together with mass and strain sensors. The fact that graphene offers some
advantages over this entire range of sensing modalities is an indication of its versatility and
importance.

Tactile sensors using the distributed
optical fibersensors
Abstract:
This paper describes two kinds of the tactile sensors using the optical fiber sensors. One is
the tactilesensor using fiber Bragg grating (FBG) sensor. Bragg grating inscribed in an
optical fiber causes reflect of a spectral component at the Bragg wavelength.
This sensor can detect external force using change of the reflective wavelength. The other
is the tactile sensor using the microbending optical fiber (MBOF)sensors. The microbending
of the optical fiber drives the light transmission loss from the optical fiber. Using the light
loss, this sensor can also detect the external force. The structures of these type
tactilesensors are very simple. The tactile sensor using FBG sensor consists of an optical
fiber which has a Bragg grating and bridge type transducers, and using MBOF sensors is
composed of crossed fibers in the silicone rubber. In this paper, we fabricated and
evaluated both tactile sensors. The performances of both tactile sensors were verified.

2. An extended LLRPmodel for RFID system
test and diagnosis
Abstract:
In recent years, radio frequency identification (RFID) systems have been increasingly used
in critical domains such as medical field or real-time processing domains. Although
important efforts have been made to make this technologymore reliable and fault-tolerant,
more research is needed to meet the increasing dependability requirements. In this article,
we propose a dependability approach consisting in two steps. The first one is an analysis of
RFID systems in order to identify potential failures of RFID middleware components and
their effects on the whole system. The second one is the modelling of the communication
behaviour of RFID systems (that is represented by Low Level Reader Protocol1) as a finite
state machine. This protocol FSM will be extended to take into consideration the failures
identified in the first step and serves as a diagnosis and test tool for the RFID system.

HEALTH
Continuous and Automated Measuring of
Compliance of Hand-Hygiene Procedures
Using Finite State Machines and RFID
Abstract:
Health care associated infections (HAIs) affect up to one in twenty hospitalizations or 1.7
million persons annually in the U.S., exceeding four billion dollars in costs [1] and resulting
in approximately 100,000 deaths. In Europe, there are an estimated five million annual
cases of general nosocomial infections, infections acquired in a hospital, with 2.7% of cases
(135,000 annually) being a contributor to death [2]. Although many factors contribute to the
development of HAIs, hand hygiene is considered the single most important measure for
limiting nosocomial transmission of pathogens [3]. Hand hygiene compliance is generally
considered to be suboptimal and remains a constant challenge for infection control
programs. Health regulatory and advisory agencies, such as the World Health Organization
(WHO), the Centers for Disease Control and Prevention (CDC), and The Joint Commission,
all recommend or demand that hospitals monitor hand hygiene compliance.

Vehicle Model without Velocity
Measurement
Abstract:
This paper presents a method to design guidanceand control laws for small Vertical Take
Off and LandingUnmanned Aerial Vehicles when no measurement of linearvelocity nor
angular velocity is available. The control strategyis based on the introduction of virtual
states in the stateequation of the system and allows the design of stabilizingfeedback
controllers without using any observer. Simulationresults are provided for a six degrees of
freedom model of asmall rotorcraft-based Unmanned Aerial Vehicle.

Abstract:
According to the characteristic of GPS direct signal and reflection signal, unmanned aerial
vehicle's altitude transducer and GPS navigationequipment are integrated to a miniature
detentionmapping receiver system. The GPS terrain echosignal mathematics equation has
been inferred, the height measuring model which reflects the landsurface characteristic has
been established. Thus theGPS satellite is taken as the illumination source, thereceiver is
put on the unmanned aerial vehicle, theunmanned aerial vehicle guidance localization
andthe height measuring control simulation system arecarried on separately using the GPS
direct signaland the land reflected signal. The parallel processingof unmanned aerial vehicle
guidance pulse, the GPSreflection signal and receiver is realized, whichreduces unmanned
aerial vehicle's payload, andraises system's operating efficiency. The analysis ofsimulation
result confirms the model validity, whichprovides the basis for the following the
unmannedflight control system optimization design.
