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.

Generation of audio and ultrasonic signals and measuring ultrasonic response in dual-mode MEMS speaker

A MEMS speaker that may include a membrane positioned in a first plane, wherein the membrane may be configured to oscillate at a first frequency thereby generating an ultrasonic acoustic signal; and an acoustic modulator that may include a blind and a shutter; wherein the blind may be positioned in a second plane; wherein the shutter may be positioned in a third plane; wherein the first plane, the second plane and the third plane may be substantially separated from each other; and wherein the acoustic modulator may be configured to (a) receive or generate a shutter control signal and a blind control signal, and (b) modulate, in response to the shutter control signal and the blind control signal, the ultrasonic acoustic signal such that an audio signal may be generated.

Pico-speaker acoustic modulator

A method of charge reuse, the method may include repeating the steps of: electrically coupling a first group of capacitive loads to a second group of capacitive loads; wherein the capacitive loads of the first group and of the second group are Microelectromechanical systems (MEMS) capacitive loads or Nanoelectromechanical systems (NEMS) capacitive loads; charging the second group with a first charge provided from the first group; electrically disconnecting the first group from the second group; operating the second group while using the first charge; electrically coupling the first group to the second group; charging the first group with a second charge provided from the second group; electrically disconnecting the first group from the second group; and operating the first group while using the second charge.

Energy efficient charge reuse in driving capacitive loads

An ultra low energy (ULE) digital enhanced cordless telecommunication (DECT) base station that includes a scheduler that is arranged to dynamically determine a schedule of transmissions of broadcast messages and of paging messages to be received by DECT ULE devices; a dummy bearer generator arranged to generate dummy bearers in response to the schedule; wherein each dummy bearer comprises a multiple usage field and a usage indicative field; wherein the usage indicative field is indicative of a selected usage of the multiple usage field; wherein the selected usage purpose is selected out of at least a conveyance of a broadcast message and a conveyance of a paging message; a configuration module that is arranged to generate location information indicative of a location of at least one bit allocated within at least one dummy bearer for indicating, when flagged, of a presence of a paging message or a broadcast message aimed to at least one of the DECT ULE devices; and a transmitter that is arranged to transmit to the DECT ULE devices the dummy bearers and the location information.

System, method and computer readable medium for DECT ULE paging and broadcast

A system may be provided and may include a first transmitter; a first antenna, coupled to the first transmitter; wherein the first transmitter is arranged to transmit via the first antenna first radio frequency (RF) signals; a first receiver; a second antenna, coupled to the first receiver; the second antenna differs from the first antenna; an RF acquisition module that is arranged to acquire second RF signals that are representative of the first RF signals; and an RF suppression module, arranged to receive the second RF signals and to generate RF suppression signals for suppressing an effect of a transmission of the first RF signals on the first receiver, and to provide the RF suppression signals to the first receiver.

System for allowing co-existence of transceivers

A caching filter driver which is adapted for communicating with a universal serial bus (USB) mass storage device, the caching filter driver is adapted to: (a) receive a first reading request for a first size data from a USB mass storage driver; (b) determine if requested data which is requested in the first reading request is included in a prefetched read data cache; (c) issue a second reading request for a second size data to the USB mass storage device; and store the second size data in the prefetched read data cache, if the requested data is not included in the prefetched read data cache; and to (d) provide the requested data from the prefetched read data cache; wherein the second size is larger than the first size and the second size data includes the first size data; wherein the caching filter driver resides below the USB mass storage driver.

Method and system for communicating with a universal serial bus device

A universal serial bus (USB) communication system, the system includes: (a) a wired communication component, which is adapted to receive a received USB transfer; (b) a processor which is adapted to process the received USB transfer to provide a transmittable wireless USB transfer; and (c) a wireless communication component, which is adapted to transmit the transmittable wireless USB transfer; wherein the system is adapted to transmit a portion of the transmittable wireless USB transfer before the entire received USB transfer is received.

Method and system for transmitting USB communication

An intermediate device, including: (a) a wired USB communications component; (b) a wireless USB communications component; (c) a memory unit; (d) a processor, connected to the wired USB communications component, to the wireless USB communications component and to the memory unit, and (e) a USB class compliant driver emulator constructed in response to at least one characteristic of the USB device.
