The author investigated the possibility of developing a myoelectric elbow prosthesis powered by an ultrasonic motor. Ultrasonic motors have some features that make them uniquely suited to powering prosthetics: they deliver high torque under low-speed operation, they are compact in size and they produce no electromagnetic noise. Typically, the threshold-level of an EMG (electromyogram) is adopte...

The work is devoted to the problem of frequency-selective signal conversion in microelectronic sensor devices. It has been shown that path such devices, particular, nodes concept Internet Things, must meet requirements embedded systems using a mixed analog-digital front end. analysis transformation photovoltaic sensors, particular significant parasitic influence extraneous non-informative optic...

Major impediments to technology scaling in the nanometer regime include power (or energy) dissipation and “erroneous” behavior induced by process variations and noise susceptibility. In this paper, we demonstrate that CMOS devices whose behavior is rendered probabilistic by noise (yielding probabilistic CMOS or PCMOS) can be harnessed for ultra low energy and high performance computation. PCMOS...

Wearable physiological monitoring systems have gained popularity in the recent years due to their ability to continuously monitor physiological signals, thereby making them suitable for home-healthcare applications. The electrocardiogram (ECG), phonocardiogram (PCG) and photoplethysmogram (PPG) signals have been studied and it has been observed that there is a correlation between the three sign...

An automatic test environment (ATE) based on a PSoC has been developed to perform electrical characterization of integrated circuits (ICs). The ICs are designed for academic and research purposes as part of the Electronic Design graduate program at CINVESTAV-Guadalajara Unit; these ICs are manufactured in standard N-well, 5-V, 1.5μm/0.5μm CMOS technologies. The ATE offers programmable capabilit...

This work proposes design of a low power sensor node which acquires ECG signal, process and transmits it over wireless medium. Programmable System on Chip (PSoC) processor performs rapid, complex signal processing and consumes low power. These PSoC’s capabilities extend its use in designing intelligent wireless sensor node. ECG detection and processing system detects R peaks at regular interval...

This paper describes the purpose of development for RtrASSoc, an Adaptable, Superscalar and Reconfigurable System on Chip. The RtrASSoc will be used in Embedded Systems that need capacity, performance, and low cost, based on Programmable System-on-Chip (PSOC), where part of the system will be a embedded superscalar processor (ESP), another part will be a Embedded Operating System (EOS), and fin...

A novel histogram generation hardware architecture, which can develop histogram for all types of grayscale images of size (256 x 256), is presented in this paper. The histogram produced from the proposed hardware gives exactly the same information as obtained from a histogram plot using simulation tool like Matlab with 100 percent accuracy. Hardware realization of the architecture makes it suit...
