Foot Plantar Pressure Measurement System: A Review

Foot plantar pressure is the pressure field that acts between the foot and the support surface during everyday locomotor activities. Information derived from such pressure measures is important in gait and posture research for diagnosing lower limb problems, footwear design, sport biomechanics, injury prevention and other applications. This paper reviews foot plantar sensors characteristics as reported in the literature in addition to foot plantar pressure measurement systems applied to a variety of research problems. Strengths and limitations of current systems are discussed and a wireless foot plantar pressure system is proposed suitable for measuring high pressure distributions under the foot with high accuracy and reliability. The novel system is based on highly linear pressure sensors with no hysteresis.

Modeling and simulation of finite state machine Memory Built-in Self Test architecture for embedded memories

Memory built-in self test (MBIST) or as to it array built-in self test is an amazing piece of logic. Without any direct connection to the outside world, a very complex embedded memory can be tested efficiently, easily and less costly. Modeling and simulation of finite state machine (FSM) MBIST is presented in this paper. The design architecture is written in very high speed integrated circuit hardware description language (VHDL) code using Xilinx ISE tools. The architecture is modeled and synthesized using register transfer level (RTL) abstraction. Verification of this architecture is carried out by testing stuck at fault SRAM. A BIST algorithms is implemented i.e March C- to test the faulty SRAM.

Implementing Gabor Filter for fingerprint recognition using Verilog HDL

This paper present the implementations of Gabor filter for fingerprint recognition using Verilog HDL. This work demonstrates the application of Gabor Filter technique to enhance the fingerprint image. The incoming signal in form of image pixel will be filter out or convolute by the Gabor filter to define the ridge and valley regions of fingerprint. This is done with the application of a real time convolve based on Field Programmable Gate Array (FPGA) to perform the convolution operation. The main characteristic of the proposed approach are the usage of memory to store the incoming image pixel and the coefficient of the Gabor filter before the convolution matrix take place. The result was the signal convoluted with the Gabor coefficient.

Car Ignition System via Mobile Phone

SMS text messaging is the most popular and widely used data application in this era for sending text messages from one mobile to another. Short Message Service (SMS) is a communications protocol allowing the interchange of short text messages between mobile telephone devices [7]. Short messages can be encoded using a variety of alphabets. The implementation of Car ignition system through mobile phone consists of 2 parts: software design and hardware development. The software part is designed by using Dynamic and loads the program into Rabbit Core Module (RCM3200). The data loaded into RCM3200 will be saving at the memory. The hardware parts are Rabbit Core Module (RCM3200) with Prototyping Board (RCM3100), GSM/GPRS modem: Wavecom 900/1900 MHz Machine-to-Machine (M2M) and bipolar junction transistor (BJT) circuit. The system purpose is to ignite the car engine by using the mobile phone. By sending a text message (SMS) from mobile phone, the system could ignite the engine. The advantage of this system is user could ignite their car engine wherever they parked their car whether near or far distance from the user. The engine will run for 5 minute without unlocks the door.

Implementing digital finite impulse response filter using FPGA

This paper describes the design of Transposed Form FIR filter implemented in the Spartan-II and Virtex-E family of FPGAs. The design is an 8-tap filter based on 16-bit input samples and 14-bit signed coefficients. The basic building blocks of the filter are KCMs, Adders, Registers, and a delay-locked loop. All the 14-bit coefficient factors are stored with an 18-bit word size in the ROM. The program is written in VHDL source code based on application Xilinx notes [1] that describe the design of an FIR filter. The software tools have been used are Xilinx ISE Webpack 8.1, ModelSim 6.1e and Matlab 7.0.

Comments and Reply to: Foot Plantar Pressure Measurement System: A Review. Sensors 2012, 12, 9884-9912

We would like to comment on a recent review article published in Sensors by Razak et al. [1]. The authors provided a review of plantar pressure measurement systems which included the discussion of the recently developed WalkinSense® system. While the authors correctly identified that our group completed research using this system [2], they have inaccurately reported the manufacturer of the system and our research findings.

Capability of Indium Tin Oxide as a sensing mechanism for engine oil degradation monitoring

This paper presents the capabilities of glass Indium Tin Oxide (ITO) for engine oil degradation sensing monitoring system with resistive application. The glass ITO is a resistive material which has the ability to measure oil samples in resistive. This material is ideal with its durability and heat resistant characteristics. The characteristics of Indium Tin Oxide will be measured in voltage and resistance with suitable ROIC circuit interface. Aim for this research is to classify the resistance value with the same type engine oil with different lifespans. It is believe that this new type bulk resistive material can improve the oil degradation sensing in automotive application and cheaper manufacturing. A simple innovation system is constructed to provide oil conditioning in vehicle with implementing the small glass ITO at the end of the dipstick. This innovation is more precise way to determine the oil degradation with conditioning method.

Mobile Carbon Monoxide Monitoring System Based on Arduino-Matlab for Environmental Monitoring Application

Nowadays, the increasing level of carbon monoxide globally has become a serious environmental issue which has been highlighted in most of the country globally. The monitoring of carbon monoxide content is one of the approaches to identify the level of carbon monoxide pollution towards providing the solution for control the level of carbon monoxide produced. Thus, this paper proposed a mobile carbon monoxide monitoring system for measuring the carbon monoxide content based on Arduino-Matlab General User Interface (GUI). The objective of this project is to design, develop and implement the real-time mobile carbon monoxide sensor system and interfacing for measuring the level of carbon monoxide contamination in real environment. Four phases or stages of work have been carried out for the accomplishment of the project, which classified as sensor development, controlling and integrating sensor, data collection and data analysis. As a result, a complete design and developed system has been verified with the handheld industrial standard carbon monoxide sensor for calibrating the sensor sensitivity and measurement in the laboratory. Moreover, the system has been tested in real environments by measuring the level of carbon monoxide in three different lands used location; industrial area; residential area and main road (commercial area). In this real environment test, the industrial area recorded the highest reading with 71.23 ppm and 82.59 ppm for sensor 1 and sensor 2 respectively. As a conclusion, the mobile realtime carbon monoxide system based on the Arduino-Matlab is the best approach to measure the carbon monoxide concentration in different land-used since it does not require a manual data collection and reduce the complexity of the existing carbon monoxide level concentration measurement practise at the same time with a complete data analysis facilities.
