Abstract: A light detection and ranging (LIDAR) system transmits, towards a target, a set of chirp signals. The LIDAR system receives from the target, a set of adjusted chirp signals. The LIDAR system then determines, based on the set of adjusted chirp signals, a degree of ghosting mitigation to compensate for a ghost target appearing in a point cloud at a location where no real target exists.

Abstract: A light detection and ranging (LIDAR) system has a passive modulator to modulate a light signal from an optical source with a low-power mode at a section of a sweep signal to generate a pulsed light signal transmitted towards a target. The LIDAR system has a photodetector to receive a return beam from the target with an amplitude modulated (AM) signal portion and a frequency modulated (FM) signal portion. The LIDAR system determines a target range value for the target based on the AM signal portion and determines a target velocity value for the target based on the FM signal portion.

Abstract: Test circuitry includes a scan-compressor receiving n scan-input bits from n input-pins and compressing those bits for distribution among z scan-chains, z being less than n. A scan-decompressor receives test response data from the scan-chains and decompresses the test response data, reconstructing n scan-output bits. An OCC generates a test-clock based on clock-bits received from a clock-chain, with the test-clock operating the scan-chains and the clock-chain. The clock-chain receives m clock-chain input bits from m of the input-pins, m being less than n, and provides the clock-bits to the OCC for generating the test-clock. The test circuitry performs tests on the IC. Each test is associated with the test-clock generated by the OCC based on a given set of clock-bits. Tests associated with the test-clock generated by the OCC based on the same given set of clock-bits are performed after a single loading of that same given set of clock-bits.

Abstract: The disclosed communication skills training tool identifies and analyzes target user data from a multi-user collaboration tool or a live event to provide communication skills training feedback to a target user. The target user is identified based on target user characteristics in the received signal from the multi-user collaboration tool or an input at the live event. A target user performs in a communication event with multiple users on a multi-user collaboration tool or a live event. A signal that includes data from the target user and excludes data from the other users is analyzed to determine feedback appropriate for the target user. That analyzed data is output either in real-time or asynchronously via post-event review.

Abstract: A light detection and ranging (LIDAR) system to transmit optical beams including at least up-chirp frequency and at least one down-chirp frequency toward targets in a field of view of the LIDAR system and receive returned signals of the up-chirp and the down-chirp as reflected from the targets. The LIDAR system may determine multiple frequency peaks associated with the target based on the returned signals. Upon determining that at least one of the multiple frequency peaks is within one or more sets of frequency ranges, the LIDAR system may combine an in-phase signal and a quadrature signal of the returned signals to generate a complex signal that enables determining whether the at least one of the multiple frequency peaks is associated with ghosting. Upon determining to be free from ghosting, the LIDAR system determines one or more of the target location, a target velocity, and a target reflectivity.

The AGC unit can measure a power of the return beam, and apply variable gain in the frequency domain to reduce a dynamic range of the return beam to a second dynamic range lower than the first dynamic range.

Abstract: A light detection and ranging (LIDAR) system to transmit an optical beam toward a target and receive a returned optical beam. The optical beam includes an up-chirp frequency and a down-chirp frequency, and is modulated to have phase non-linearities. The LIDAR system generates a baseband signal from the returned optical beam, which includes a plurality of peaks corresponding with the up-chirp frequency and the down-chirp frequency. The LIDAR system identifies a first true peak in the baseband signal, and identifies a second true peak in the baseband signal based, at least in part, on a spectral shape of the second true peak caused by the phase non-linearities. The LIDAR system is to determine the location of the target using the first true peak and the second true peak.

Abstract: An electronic device tracks its motion in an environment while building a three-dimensional visual representation of the environment that is used to correct drift in the tracked motion. A motion tracking module estimates poses of the electronic device based on feature descriptors corresponding to the visual appearance of spatial features of objects in the environment. A mapping module builds a three-dimensional visual representation of the environment based on a stored plurality of maps, and feature descriptors and estimated device poses received from the motion tracking module. The mapping module provides the three-dimensional visual representation of the environment to a localization module, which identifies correspondences between stored and observed feature descriptors. The localization module performs a loop closure by minimizing the discrepancies between matching feature descriptors to compute a localized pose.
