Miniaturized Resonant Power Conversion for Implanted Medical Devices

Multi-resonant passive components for power conversion

Implanted Medical Devices Safe from Hackers

Implantable medical devices— such as insulin pumps, cardiac pacemakers, and cardiac defibrillators—have become increasingly popular since being introduced about 50 years ago. In the US alone, 2.6 million people rely on IMDs. An increasing number of today’s devices are equipped with wireless technology enabling, for example, remote checks by healthcare workers. “Patients often receive at-home, b...

Implementation of Automatic Speech Recognition for Low-Power Miniaturized Devices

This paper describes the development and implementation of a discrete speech recognizer for application in miniaturized, portable low-power devices. The recognizer is based on Hidden Markov Models (HMMs) and uses Linear Predictive Coefficients (LPC) converted to cepstrum to parameterize the input speech. The implemented recognizer has a complexity of 0.67 MIPS and a recognition performance of 9...

Frequency-Selective MEMS for Miniaturized Low-Power Communication Devices

With Q’s in the tens to hundreds of thousands, micromachined vibrating resonators are proposed as integratedcircuit-compatible tanks for use in the low phase-noise oscillators and highly selective filters of communications subsystems. To date, LF oscillators have been fully integrated using merged CMOS/microstructure technologies, and bandpass filters consisting of spring-coupled micromechanica...
