Abstract: A method for providing codewords, the method may include receiving by an input buffer, one or more chunks of data; calculating a location of relevant bits within one or more chunks of data; wherein the relevant bits comprise (a) variable length retrieval information used during a retrieval process of a first type codeword, or (b) a second type codeword; performing the retrieval process of the first type codeword and retrieving the first type codeword from a memory unit that stores only a fraction of a codebook, the codebook comprises first type codewords and second type codewords; determining whether the relevant bits comprises the second type codeword or not; and outputting the second type codeword or the first type codeword, based on the determination.

Abstract: A method for charge-reuse, the method may include performing multiple repetitions of the steps of: operating a second capacitive load while the second capacitive load is disconnected from a first capacitive load; wherein the second capacitive load is a Microelectromechanical systems (MEMS) capacitive load or a Nanoelectromechanical systems (NEMS) capacitive load; electrically coupling a first capacitive load to a second capacitive load via a path that comprises an inductor; charging the first capacitive load with a second charge provided from the second capacitive load; electrically disconnecting the first capacitive load, the second capacitive load and the inductor from each other; feeding the inductor with a supply current provided by a supply circuit; disconnecting the inductor from the supply circuit and coupling the inductor to the first capacitive load; charging the first capacitive load by the inductor; electrically coupling the first capacitive load to the second capacitive load via the path that comprises the inductor; charging the second capacitive load with a first charge provided from the first capacitive load; and operating the second capacitive load while the second capacitive load is disconnected from the first capacitive load.

Abstract: Methods and systems are provided for enhanced stereo audio recordings in electronic devices. Stereophonic recording performance in an electronic device, using a first microphone and a second microphone in the electronic device, may be assessed; and processing of signals generated by the first microphone and the second microphone may be configured based on the assessed stereophonic recording performance. The configuring may comprises adaptively modifying the processing to enhance stereophonic recording performance, to match or approximate an ideal performance. The assessing of the stereophonic recording in the electronic device may be based on a type of each of the first microphone and the second microphone, and/or based on a spacing therebetween. The processing may be adaptively modified to simulate directional reception of signals by the first microphone and the second microphone when the microphones are omnidirectional.

Abstract: In a mobile device, a bone conduction or vibration sensor is used to detect the user's speech and the resulting output is used as the source for a low power Voice Trigger (VT) circuit that can activate the Automatic Speech Recognition (ASR) of the host device. This invention is applicable to mobile devices such as wearable computers with head mounted displays, mobile phones and wireless headsets and headphones which use speech recognition for the entering of input commands and control. The speech sensor can be a bone conduction microphone used to detect sound vibrations in the skull, or a vibration sensor, used to detect sound pressure vibrations from the user's speech. This VT circuit can be independent of any audio components of the host device and can therefore be designed to consume ultra-low power. Hence, this VT circuit can be active when the host device is in a sleeping state and can be used to wake the host device on detection of speech from the user. This VT circuit will be resistant to outside noise and react solely to the user's voice.
