An open-architecture microsystem that can be populated with a variety of sensors and actuators is described. The microsystem is designed for low-power wireless applications where small size and high sensor accuracy are important. It consists of an in-module microcontroller connected to multiple front-end transducers through an intramodule sensor bus. An(More)
This paper reports a mixed-voltage mixed-signal chip for interfacing multiple capacitive transducers to embedded processors in integrated microsystems. A programmable switched-capacitor readout circuit accommodates capacitive sensors from 16 fF to 40 pF and allows self-test and online calibration. The 20 mm chip has a sensitivity of 1.25 mV/fF and is(More)
Heat is fundamental to power generation and many industrial processes, and is most useful at high temperatures because it can be converted more efficiently to other types of energy. However, efficient transportation, storage and conversion of heat at extreme temperatures (more than about 1,300 kelvin) is impractical for many applications. Liquid metals can(More)
SEPTEMBER/OCTOBER 2010 ■ 1540-7993/10/$26.00 © 2010 IEEE ■ COPUBLISHED BY THE IEEE COMPUTER AND RELIABILITY SOCIETIES 57 Bruce Potter The Shmoo Group have their own tools as well—no need to pay for malware when you can build your own. Potentially most disturbing is the increased sophistication in the back-end command-and-control mechanisms that attackers(More)
Mobile robotics is a growing trend in recent years as mobile robots are being used in service as well as industrial sectors. This paper introduces a novel design of a mobile robot platform for use in constrained workplaces. The constrained environments are nothing but congested places, for example hospitals, ware houses, offices, shop floors where various(More)
An internal mobile bracket, also known as its metal body, is the main supporting structure of a mobile phone to which all other components are attached, comparable to the skeleton of an organism. The goal of fault detection system is to handle occurring faults in the bodt as in the dimensions, the slots of the small bolts, the camera placement slots, the(More)
