摘要： A microphone system includes a diaphragm suspended by springs and including a sealing layer that seals passageways which, if left open, would degrade the microphone's frequency response by allowing air to pass from one side of the diaphragm to the other when the diaphragm is responding to an incident acoustic signal. In some embodiments, the sealing layer may include an equalization aperture to allow pressure to equalize on both sides of the diaphragm.

摘要： A microphone module has a substrate with an aperture to allow sound waves to pass through the substrate, a lid mounted to the substrate to define a first interior volume, a microphone mounted to the substrate within the first interior volume, and a housing coupled to the substrate and covering the aperture. The housing forms a second interior volume and includes an acoustic port configured to allow sound to enter the second interior volume. The module further includes a pipe extending from the acoustic port in the housing, and at least one exterior interface pad outside of the second interior volume. The pipe has an open end to receive sound waves and direct them toward the acoustic port in the housing. Moreover, the at least one exterior interface pad electrically couples to the microphone.

摘要： A method of writing to magnetic tunnel junctions (MTJs) of a magnetic memory array includes storing in-coming data in a cache register, reading the present logic state of a first one of a set of at least two MTJs, the set of at least two MTJs including the first MTJ and a second MTJ. The in-coming data is to be written into the second MTJ. Further steps are storing the read logic state into a data register, swapping the contents of the data register and the cache register so that the cache register stores the read logic state and the data register stores the in-coming data, applying a first predetermined voltage level to the set of MTJs thereby causing the first MTJ to be over-written, applying a second predetermined voltage level to the set of MTJs, and storing the in-coming data into the second MTJ.

摘要： This invention relates to provisioning wavelength-selective switches and reconfigurable optical add-drop multiplexers to minimize the bandwidth narrowing effect from the optical filters. Novel architectures and methods are disclosed that can significantly reduce bandwidth-narrowing on channels in a reconfigurable WDM network where a large number of optical filter elements are cascaded. Instead of blocking unused channels as in the prior art, unused channels are selectively provisioned depending on the state of their adjacent channels. Unused adjacent channels of an active channel are provisioned to follow the same path as the active channels. As each channels is deployed, the channel frequency is selected so as to minimize bandwidth narrowing.

摘要： A microphone system has a primary microphone for producing a primary signal, a secondary microphone for producing a secondary signal, and a selector operatively coupled with both the primary microphone and the secondary microphone. The system also has an output for delivering an output audible signal principally produced by one of the to microphones. The selector selectively permits either 1) at least a portion of the primary signal and/or 2) at least a portion of the secondary signal to be forwarded to the output as a function of the noise in the primary signal.
