This paper investigates the capability of Acoustic Energy Harvesters (AEH) in generating electricity to minimize electricity consumption. In AEHs, piezoelectric materials convert mechanical stress into electrical energy. It generates electricity with the application of stimulus such as pressure or sound. This paper reports on the study of a commercial passive piezoelectric transducer effect on an...
Foot plantar pressure is the pressure fields that act between the foot skin and its supporting surface that humans experience during daily activities. Information derived from such pressure is important for diagnosing lower limb problems, footwear design, sport biomechanics performance and injury prevention. This paper presents the design and implementation of a wireless data acquisition integrated...
Obstacle detection is one of the important aspects to be considered in the development of smart assistive devices. The latest mobility assistive devices are equipped with this function as a safety precaution for the users to avoid obstacles in their path. In this project, a wireless, miniature, low cost, obstacle detection system is proposed. The system is based on optical sensors which can detect...
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...
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...
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...
