Abstract: A communications subsystem for a wireless device for correcting errors in a reference frequency signal. The communications subsystem comprises a frequency generator for generating the reference frequency signal and a closed loop reference frequency correction module that generates a reference frequency adjustment signal for correcting the reference frequency signal when the communications subsystem operates in closed loop mode. The subsystem further includes an open loop frequency correction means that that samples values of the reference frequency adjustment signal during the closed loop mode and generates a frequency correction signal for correcting the reference frequency signal when the communications subsystem operates in a mode other than closed loop mode.

Abstract: The settling time of a wireless receiver is reduced by providing a previously utilized gain control state value to a low noise amplifier (LNA) of a receiver front end during a warm-up portion of a wake-up period of the wireless receiver which follows a sleep period. One illustrative method includes the steps of receiving a notification signal which indicates that the wireless receiver is to be placed in a sleep mode, reading a gain control state value from a gain controller based on receiving the notification signal, storing the gain control state value in memory, providing the stored gain control state value from the memory to the wireless receiver during a warm-up period of a second wake-up period following the first wake-up period, and providing a gain control state value from the gain controller to the wireless receiver based on a signal level of a currently received signal of the wireless receiver after the warm-up period.

Abstract: A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.

Abstract: Radar and LiDAR sensors play important roles in autonomous vehicles and ADAS (advanced driving assistance systems) in automobiles, however, they can only detect objects in view (line-of-sight). For example, when three vehicles are driving on road in a same lane, and if the first vehicle suddenly brakes, the third vehicle cannot detect it by regular radar and/or LiDAR because the second vehicle in front blocks the view. This invention discloses system and method to enable radar and/or LiDAR to detect vehicles on road that are blocked in view by another vehicle by specially configured active beacon transmitters, and reduce risks of rear-end collisions.

Abstract: A maxillary tuberosity holding bite block is disclosed. The maxillary tuberosity holding bite block includes a curved tail that embraces a patient's maxillary tuberosity, which allows the bite block to hold the patient's jaws in a stable position, regardless of whether or not the patient has edentulous jaws. Moreover, the maxillary tuberosity holding bite block may serve as a carrier for sensors and endoscopes so it may serve as an intra-oral sensor-based positioning and navigation device that sense and track the movement and position of sensor-equipped surgical instruments.

Abstract: A method of updating map data entails capturing an image using a camera, determining a location of an object in the image, creating new map data to represent the object in the image, and updating a map database to include the new map data for the object in the image. This method may be implemented on a GPS-enabled wireless communications device having an onboard camera which can transmit the new map data to a map server for updating its map database. Determining the position of the object in the image relative to the wireless device may be accomplished using a rangefinder and compass, triangulation of multiple images of the object, or a stereoscopic camera. The accuracy of the GPS position fix may be improved by capturing images of recognizable objects for which location coordinates are available.
