摘要： An electret formed by micro-machining technology on a support surface, including a self-powered electret sound transducer, preferably in the form of a microphone, formed by micro-machining technology. Each microphone is manufactured as a two-piece unit, comprising a microphone membrane unit and a microphone back plate, at least one of which includes an electret formed by micro-machining technology. When juxtaposed, the two units form a microphone that can produce a signal without the need for external biasing, thereby reducing system volume and complexity. The electret material used is a thin film of spin-on polytetrafluoroethylene (PTFE). An electron gun preferably is used for charge implantation. The electret has a saturated charged density in the range of about 2null10null5 C/m2 to about 8null10null4 C/m2. Thermal annealing is used to stabilize the implanted charge. An open circuit sensitivity of about 0.5 mV/Pa has been achieved for a hybrid microphone package.
摘要翻译：通过微加工技术在支撑表面上形成的驻极体，其包括通过微加工技术形成的优选以麦克风形式的自供电的驻极体声音传感器。每个麦克风被制造成两件式的单元，其包括麦克风膜单元和麦克风背板，其中至少一个包括由微加工技术形成的驻极体。当并置时，两个单元形成麦克风，其可以产生信号而不需要外部偏置，从而降低系统体积和复杂性。使用的驻极体材料是旋涂聚四氟乙烯（PTFE）的薄膜。电子枪优选用于电荷注入。驻极体的饱和带电密度在约2×10 -5 C / m 2至约8×10 -4 C / m 2的范围内。热退火用于稳定植入电荷。对于混合麦克风封装已经实现了约0.5mV / Pa的开路灵敏度。

摘要： Artificial muscles comprising a body of dielectric elastomer, wherein the body contains a pair of microfluidic networks are presented. Each microfluidic network includes a plurality of channels fluidically coupled via a manifold. The channels of the microfluidic networks are interdigitated and filled with conductive fluid such that each set of adjacent channels functions as the electrodes of an electroactive polymer (EAP) actuator. By using the manifolds as compliant wiring to energize the electrodes, artificial muscles in accordance with the present disclosure mitigate some or all of the reliability problems associated with prior-art artificial muscles.

摘要： An RF lens includes a multitude of radiators adapted to transmit radio frequency electromagnetic EM waves whose phases are modulated so as to concentrate the radiated power in a small volume of space in order to power an electronic device positioned in that space. Accordingly, the waves emitted by the radiators are caused to interfere constructively at that space. The multitude of radiators are optionally formed in a one-dimensional or two-dimensional array. The electromagnetic waves radiated by the radiators have the same frequency but variable amplitudes.

摘要： A method and system provide the ability to compile computer source code. The source code is pre-processed to generate pure source code that includes definitions required for interpretation. The pure source code is formalized in a compiler, into assembly language that is processor specific. The formalization includes determining a set of two or more optimization routines, randomly selecting a selected optimization routine from the set of two or more optimization routines, and applying the selected optimization routine to each segment of the pure source code in a serialized manner. An executable binary file is then output and executed based on the formalized pure source code.

摘要： Methods and compositions are provided for the selective activation of a BMP-dependent response in certain cell types. Methods include identifying a ligand or ligand combinations as well as cell receptor profiles that result in selectively activating a ligand-dependent response through interactions with ligand receptors on a first cell type that do not activate the ligand-dependent response in a second cell type.
