Sleep problems and disorders have a serious impact on human health and wellbeing. The rising costs for treating sleep-related chronic diseases in industrialized countries demands efficient prevention. Low-cost, wearable sleep / wake detection systems which ...
The invention concerns a device (10) for measuring one or several navigation parameters in a large-size navigating craft, comprising a parameter sensing and measuring element (11) and at least means for displaying (12) said parameter, connected by electrom ...
In this letter, we propose a lateral asymmetric strain profile in a silicon nanowire or ultrathin silicon film as a key technology booster for the performance of all-silicon Tunnel FETs. We demonstrate by simulation that a Gaussian tensile-strain profile w ...

We consider the design of the MAC layer for low power, low data-rate, impulse-radio ultra-wide band (IR-UWB) networks. In such networks, the primary concern is energy consumption rather than rate efficiency. We explore several dimensions such as power cont ...
We studied the effects of chloramphenicol on brain glucose utilization and sleep-wake cycles in rat. After slightly anaesthetized animals were injected with [18F]fluoro-2-deoxy-D-glucose, we acquired time-concentration curves from three radiosensitive beta ...
An ultra low power 8-bit current-mode successive approximation (SAR) analog-to-digital (ADC) converter for Wireless Sensor Network (WSN) applications is presented. The proposed ADC contains a new asynchronous clock generator, which works only during data p ...
