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: Doppler LIDARs, such as those used in ADAS (advanced driver assistance system) and autonomous vehicles, may need to sense objects at many directions. Some of the Doppler LIDAR devices use mechanically moving parts to scan over a range of directions and the various directions are not sensed simultaneously but sensed in turns over time. Mechanically moving parts generally have higher costs, less reliability and shorter Mean Time To Failure (MTTF). The camera sensor for LIDAR with Doppler-sensing pixels disclosed herein uses a Doppler sensing-chip that enables Doppler LIDAR devices to sense many directions simultaneously without having to use mechanical scan and mechanically moving parts, at least reduce the use thereof. Lower costs and higher reliability as well as higher direction sensing accuracy are objectives of this invention.

Abstract: For people with reduced physical ability such as elderly people, risks of bodily injuries are high. Once an injury occurs, a victim suffers, sometimes a victim even may not survive. To help such people, a device without adding much inconvenience in normal life is disclosed. The device is able to detect dangerous conditions and automatically deploy airbags when needed to prevent or mitigate potential bodily injuries.

Abstract: In certain areas, if a drone flies into them, may cause danger to people or facilities within the area. In such areas no-fly zones need to be implemented and enforced. A no-fly zone can be indicated or identified by specially transmitted radio signals in or around the no-fly zone. No-fly zones can also be defined using geo-fence data that is provided to a drone. Once a drone detects itself within a no-fly zone, will disable the control from its original operator or from its pre-programmed flying plan at least in part, and be made harmless.

Abstract: Catastrophic earthquakes cause tremendous loss to people, especially when they occur unprepared. Imminent prediction of the earthquake with occurrence time, location and magnitude may give people time to prepare for it and minimize the loss. Unfortunately, imminent prediction of the earthquakes, especially those without foreshocks, is very difficult if not impossible. This invention discloses a method and system that work around the difficulty of the imminent prediction of the earthquake. Instead of trying to predict the occurrence, it triggers the earthquake artificially at a known time so that evacuation and other preparations can be accomplished prior to the triggering time of the earthquake to reduce the loss caused by the earthquake. The artificial triggering of the earthquakes may be implemented by at least one underground nuclear explosion.

Abstract: A method includes measuring an operating parameter of a battery of a mobile device. The measured operating parameter is translated into an equivalent series resistance (ESR) value. The ESR value is adjusted by a correction factor to generate a corrected ESR value. The capacity of the battery is determined based on the corrected ESR value. The correction factor is automatically calibrated based on the measured operating parameter.

Abstract: A peak to average power ratio signal is generated from a first mapping function that selects the peak to average power ratio signal that corresponds to the data rate or data format of the signal to be transmitted. The selected peak to average power ratio signal is summed with a desired average transmit power signal. The resulting summation signal is input to a second effectively continuously valued mapping function comprising a table that has a plurality of power amplifier control signal values each with a corresponding peak transmit power. Each peak transmit power signal value results in a power amplifier control signal value that achieves the best possible transmitter power efficiency while still meeting out of band spurious emissions and waveform quality requirements. The summation signal value maps to one of the power amplifier control signal value that is then used to adjust a parameter such as bias of the power amplifier.
