We present TinyWifi, a nesC code base extending TinyOS to support Linux powered network nodes. It enables developers to build arbitrary TinyOS applications and protocols and execute them directly on Linux by compiling for the new TinyWifi platform. Using TinyWifi as a TinyOS platform, we expand the applicability and means of evaluation of wireless protocols originally designed for sensornets to...

BACKGROUND In recent years, a battery-powered bone marrow biopsy system was developed and cleared by the U.S. Food and Drug Administration to allow health care providers to access the bone marrow space quickly and efficiently. A multicenter randomized clinical trial was designed for adult patients to determine if the powered device had advantages over traditional manually-inserted needles in re...

In this paper we present an overlay infrastructure for provisioning content services over the Internet. This provides a uniform framework to develop ubiquitous application services and deploy it on a shared active infrastructure on need basis. This meta-protocol powered framework is intended to support a wide array of emerging application service scenarios, ranging from simple caching and conte...

In the last decade, many studies have been conducted on tractor and agricultural machinery electrification. particular, electrification of power take-off (PTO)-powered implements could support benefits, such as improved comfort safety during implement connection, less noisiness, accurate control rotational speed, fuel consumption reduction. However, commercially available tractors do not genera...

BACKGROUND The goal of this observational study was to determine factors predictive of the type of powered mobility prescribed to veterans with disability. MATERIAL/METHODS A retrospective chart review was conducted for all veterans (n=170) who received powered mobility from a designated power mobility clinic. Logistic regression analysis was used to determined factors predictive of the type ...

Myoelectric prostheses are generally not provided in the United Kingdom for children before the age of 3 1/2 years. Following the introduction of a smaller sized electric hand in the United Kingdom in 1993 the authors decided to introduce electrically powered hands for a group of congenital upper limb deficient children at a much younger age compared to normal practice. Eleven children were int...
