Digital Detection of Oxide Breakdown and Life-Time Extension in Submicron CMOS Technology

An approach is introduced to extend the lifetime of high-voltage analog circuits in CMOS technologies based on redundancy, like that known for DRAMS. A large power transistor is segmented into N smaller ones in parallel. If a sub-transistor is broken, it is removed automatically from the compound transistor. The principleis demonstrated in an RF CMOS Power Amplifier (PA) in standard 1.2V 90nm CMOS

SVD-based on-line exercise ECG signal orthogonalization

Cataloged from PDF version of article.An orthogonalization method to eliminate unwanted signal components in standard 12-lead exercise electrocardiograms (ECG’s) is presented in this work. A singular-valuedecomposition-based algorithm is proposed to decompose the signal into two time-orthogonal subspaces; one containing the ECG and the other containing artifacts like baseline wander and electromyogram. The method makes use of redundancy in 12- lead ECG. The same method is also tested for reconstruction of a completely lost channel. The online implementation of the method is given. It is observed that the first two decomposed channels with highest energy are sufficient to reconstruct the STsegment and J-point. The dimension of the signal space, on the other hand, does not exceed three. Data from 23 patients, with duration ranging from 9 to 21 min, are used

Investigation into suitability of current ATDs to represent ageing drivers

Ageing car occupants are expected to become a larger part of the driver and passenger population in developed countries in the future. Currently, Anthropomorphic Test Devices (ATDs) are essential tools to assess safety of automobiles; however, they do not fully embody the features of all occupant groups in the world population. This study investigates the features of ageing drivers. The data are collected and analysed with respect to age and gender. Information particularly on driverautomobile interaction is provided in the form of distances and angles measured in-car. The physical characteristics of existing ATDs are investigated and compared with the anthropometric data of ageing drivers. Comparisons indicate that the current ATDs do not incorporate some of the features of ageing drivers. The requirements of future ATDs such as sitting height, abdominal depth and posture are discussed. These specifications are essential for the development of new ATDs representing ageing drivers
