  • Publication number: 20230333229
    Abstract: Described herein are systems, methods, and non-transitory computer readable media for triggering a sensor operation of a second sensor (e.g., a camera) based on a predicted time of alignment with a first sensor (e.g., a LiDAR), where operation of the second sensor is simulated to determine the predicted time of alignment. In this manner, the sensor data captured by the two sensors is ensured to be substantially synchronized with respect to the physical environment being sensed. This sensor data synchronization based on predicted alignment of the sensors solves the technical problem of lack of sensor coordination and sensor data synchronization that would otherwise result from the latency associated with communication between sensors and a centralized controller and/or between sensors themselves.

  • Patent number: 11791936
    Abstract: Wireless devices may use polar codes for encoding transmissions and may support combining transmissions to improve decoding reliability (e.g., by achieving chase combining and incremental redundancy (IR) gains). For example, an encoding device may puncture a set of mother code bits using different puncturing patterns to obtain different redundancy versions for a first transmission and a re-transmission. Each puncturing pattern may correspond to an equivalent decoding performance. In some cases, to obtain equivalent puncture sets, the encoding device may perform punctured index manipulation procedures on an initial puncturing pattern. A punctured index manipulation procedure may involve switching a binary state for a binary bit at a same binary bit index for each puncture index in a puncturing pattern. A device may receive the transmissions generated using the equivalent puncture sets and may combine the information for improved decoding reliability.
