Abstract: An amplitude modulator circuit includes a reference oscillator and an envelope modulator coupled to the reference oscillator for receiving a reference signal. A microcontroller is coupled to the envelope modulator for providing an envelope signal to the envelope modulator and a low pass filter is coupled to the envelope modulator for receiving a modulated command from the envelope modulator. An inverter is coupled to the low pass filter for receiving a low passed envelope modulated signal from the low pass filter and a transducer or amplifier is coupled to the inverter and the low pass filter for receiving an inverted low passed signal and the low passed envelope modulated signal.
Abstract: Copolymers are manufactured to include a zwitterionic monomer (e.g., methacryloyloxyethyl phosphorylcholine monomer), a dihydroxyphenyl derivatized monomer, and optionally one or more additional monomers. The dihydroxyphenyl derivatized monomer gives the copolymers excellent adhesion properties. Optional monomers include a cationic amino monomer, a hydrocarbon monomer, and/or a hydrophilic monomer. The copolymers are biocompatible and can be used with medical devices.
Abstract: The invention relates to design of micromechanical resonators and, more precisely, to the design of microelectromechanical systems (MEMS) resonators. The invention provides an improved design structure for a microelectromechanical systems (MEMS) resonator in which the width of the spring elements (3), (23-24), (27-30) is greater than the width of the electrode fingers (5-9), (25-26), (31-34), said widths specifically dimensioned so that the sensitivity of the resonant frequency change with respect to dimensional manufacturing variations d(??0/?0)/d? approaches zero. The improved structure is frequency robust to manufacturing variations and enables reliable frequency referencing with good performance, particularly in small size solutions.
Abstract: A method of accessing a plurality of features of a second telecommunication system from a first telecommunication system includes receiving a telephone call on the second telecommunication system from a first device having a first telephone number and determining whether the first telephone number is a stored authorized number. The method further includes determining if the first telephone number is a stored authorized number, and providing access to the plurality of features if it is.

Abstract: A system for controlling the speed of a rotary blood pump. The system oscillates the speed of the pump to produce pulsed pressure at the outlet of the pump. The speed is oscillated synchronously with the natural cardiac cycle. The natural cardiac cycle is determined using a pulsatility index calculated from the back EMF produced by the pump or an impedance sensor.

Abstract: A transmitter provides a plurality of output signals. The transmitter includes a processor, a modulator, a first circuit, and a second circuit. The modulator provides a modulated signal responsive to the processor. The modulated signal includes an amplitude modulated radio frequency for transmitting a pulse. The first circuit provides a first output signal, responsive to and with higher power than the modulated signal. The first output signal has a first phase during transmitting of the pulse. The second circuit provides a second output signal, responsive to and with higher power than the modulated signal. The second output signal has a second phase during transmitting of the pulse. The second phase is controlled by the second circuit in accordance with the first phase, the second phase, and indicia of a third phase provided by the processor.
