Abstract: Methods and apparatus for facilitating the determination of Global Positioning System (GPS) location information for a mobile station without disrupting communications of a voice call (e.g. a 911 emergency call). In one illustrative example, the mobile station causes GPS navigational-type data to be regularly or periodically received and stored in memory prior to the voice call. At some point in time, the mobile station receives a voice call request to initiate the voice call. In response, the mobile station derives GPS assistance data based on the GPS navigational-type data. The mobile station then causes a GPS fix to be performed using the GPS assistance data, to thereby obtain GPS measurement data. Thereafter, the mobile station causes the voice call to be established and maintained through the wireless network. The GPS measurement data is transmitted to a location server for calculating the location of the mobile station.

Abstract: A peak power regulator is disclosed that functions within a Code Division Multiple Access (CDMA) transmitter to reduce peak power spikes within baseband signals while maintaining the average output power consistent with the average input power, controlling the out-of-band emissions, and maintaining the in-band signal quality within an acceptable degradation. In-phase and quadrature baseband signals are input to a delay block and an envelope magnitude predictor within the peak power regulator. The envelope magnitude predictor outputs an estimate for the magnitude of the envelope that will be generated when the inputted baseband signals are modulated. This estimate is input to a multiplier that generates a ratio by dividing the estimate by a maximum acceptable envelope magnitude. The ratio is subsequently input to a mapping table that outputs a scaling factor sufficient for reducing peak power spikes. The scaling factor is subsequently input to an optional mean power regulator that generates an instantaneous gain value sufficient to maintain the average output power level at the average input power level. This gain value is applied to two multipliers that are also input with delayed versions of the in-phase and quadrature baseband input signals. The outputs from these two multipliers, after being filtered within lowpass filters to remove out-of-band emissions caused by the scaling, are output from the peak power regulator. These peak power reduced outputs have any peak power spikes scale reduced while maintaining the average power constant.

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. Mechanical moving parts generally have higher costs, lower reliability and shorter Mean Time To Failure (MTTF). The LIDAR sensor on chip with Doppler-sensing pixels disclosed herein uses a Doppler sensing-chip that enables Doppler LIDAR devices to sense many directions simultaneously in parallel without having to use mechanical scan and mechanical moving parts, even without having to use electronic scan. Lower costs, higher reliability, and faster detection time as well as higher direction sensing accuracy are objectives of this invention.

Abstract: In many applications such as autonomous vehicle and ADAS (advanced driver assistance system), both LIDAR sensor and camera sensor play important and complementary roles in sensing surroundings. The scanless LIDAR sensor on chip architecture disclosed in this application is suitable to build a LIDAR and a camera sensor on a single chip and share one set of optics, enabling a combined FMCW Doppler LIDAR and camera sensor inherently to work together and jointly sense directions simultaneously in parallel without mechanical, electronic or phonic scanning, no extra efforts needed to align them either. Lower costs, higher reliability, and faster detection as well as higher direction sensing accuracy and multi-domain sensing are objectives of this invention. The combined optical sensor provides object sensing information in multiple domains: angles of view (direction vector), distance, relative velocity, colors (in Red-Green-Blue victor) and light strength.
