In this paper, we focus on an integrated system of the wireless USB over the IEEE 802.15.6 wireless body area networks (WBAN) for wireless wearable computer networks based on WiMedia MAC. However, current WBAN devices cannot share wireless channel with the existing WiMedia devices, efficiently. Existing researches are not suitable for WiMedia MAC protocol based on distributed architecture, sinc...

A Built-In Self-Test (BIST) approach has been proposed for functionality measurements of analog circuitry in mixed-signal systems. The BIST circuitry consists of a direct digital synthesizer (DDS) based test pattern generator (TPG) and multiplier/accumulator (MAC) based output response analyzer (ORA). In this paper we investigate and discuss the effects of phase delay on analog functionality me...

E laine Fuchs has collected many awards in her 30 years researching mammalian skin development, but it's hard to beat the two prizes she received in late 2009. Shortly before winning the prestigious L'Oreál-UNESCO award for women in science, Fuchs was awarded the National Medal of Science— the US's highest honor for outstanding scientifi c contributions. After studying bacterial sporulation as ...

In wireless sensor MAC protocols, duty cycling has been exploited to put sensor nodes into sleeping state most of the time, thereby saving the limited battery efficiently. In this paper, we present a MAC protocol called Hop Extended MAC (HE-MAC) that enables a source node to transmit a data packet for multiple hops in a single duty cycle. It employs an EXP (Explorer) frame to set up the path fo...
