Charles SzmandaProvided herein is a process of fractionating ferroelectric, preferably vinylidene fluoride polymers using a solvent having at least one polarizable functional group, and a precipitant. The composition of the fractionated ferroelectric polymers is selected so as to adjust the properties of a ferroel ...
Matthias BauerA method and device for detecting the rotation direction of a piston engine, internal combustion engine or piston compressor. The piston engine includes at least one cylinder, a piston movable back and forth in the cylinder, a cylinder chamber formed inside the cylinder which is delimited by an inne ...
Eugene FitzgeraldA semiconductor-based device includes a channel layer, which includes a distal layer and a proximal layer in contact with the distal layer. The distal layer supports at least a portion of hole conduction for at least one p-channel component, and the proximal layer supports at least a portion of elec ...
A technique for centralized and differentiated content and application delivery system allows content providers to directly control the delivery of content based on regional and temporal preferences, client identity and content priority. A scalable system is provided in an extensible framework for e ...
An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each proce ...
A surgical fastener for use in surgical procedures comprises a first member, a second member, and an anchor. Surgical materials may be secured within the surgical fastener. Methods of securing the surgical fastener to an anatomical structure are disclosed herein.
Provided are methods and systems for controlling the conversion of data inputs to a computer-based light system into lighting control signals. The methods and systems include facilities for controlling a nonlinear relationship between data inputs and lighting control signal ouputs. The nonlinear rel ...
The present invention provides a valve configured for insertion on the proximal and distal sides of a heart valve annulus to replace the heart valve of a patient. The valve comprises a first substantially annular portion adapted to be positioned on a proximal side of the annulus of a patient and a s ...
Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. The prostheses provide an artificial facet joint structure including an artificial articular configuration unlike the preexisting articular configuration. The radii and material stress values of the prostheses are ...
A multiple-sided medical device comprises a closed frame of a single piece of wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration that comprises a self-expanding stent. The stent is pushe ...
