摘要： A enhanced vehicle key and a method for voice activation, the method may include supplying power to a low power trigger sensor of a enhanced vehicle key, by a power source of the enhanced vehicle key; wherein the supplying of power is preceded by powering the enhanced vehicle key while a part of the enhanced vehicle key is positioned within an ignition switch of a vehicle; detecting, by the low power trigger sensor, a voice trigger; awakening, following the detection, a processor of the enhanced vehicle key; searching, by the processor, for a voice command; and when finding the voice command then executing the voice command.

摘要： A MEMS speaker that includes a control unit and multiple MEMS elements that include a membrane positioned in a first plane, a blind that is positioned in a second plane and a shutter that is positioned in a third plane. The control unit is configured to control the multiple MEMS elements to operate in an audio output mode or an ultrasonic output mode. The MEMS speaker is configured, when operating in the ultrasonic output mode, to oscillate at least one of the membrane, blind and shutter thereby generating an ultrasonic signal without audio-modulating the ultrasonic signal. The MEMS speaker is configured, when operating in the audio output mode, to oscillate the membrane thereby generating the ultrasonic signal and oscillate at least one of the shutter and the blind thereby modulating the ultrasonic acoustic signal to generate an audio signal.

摘要： A novel and useful configurable radio frequency (RF) power amplifier (PA) and related front end module (FEM) circuit that enables manipulation of the operating point of the power amplifier resulting in configurability, multimode and multiband operating capability. The configurable PA also provides high linearity and power efficiency and meets the requirements of modern wireless communication standards such as 802.11 WLAN, 3G and 4G cellular standards, Bluetooth, ZigBee, etc. The configurable power amplifier is made up of one or more configurable sub-amplifiers having each constructed to have several orders of freedom (i.e. biasing points). Each sub-amplifier and its combiner path include active and passive elements. Manipulating one or more biasing points of each sub-amplifier, and therefore of the aggregate power amplifier as well, achieves multimode and multiband operation. Biasing points include, for example, the gain and saturation point, frequency response, linearity level and EVM. An integrated multi-tap transformer having primary and secondary windings arranged in a novel configuration provides efficient power combining and transfer to the antenna of the power generated by the individual sub-amplifiers.
