摘要： Systems, methods, and computer-readable media are disclosed for a systems and methods for intra-shot dynamic LIDAR detector gain. One example method my include emitting, by an optical ranging system at a first time, a first light pulse. The example method may also include increasing, after the first time, a sensitivity of a photodetector of the optical ranging system from a first sensitivity at the first time to a second sensitivity at a second time. The example method may also include decreasing the sensitivity of the photodetector of the optical ranging system from the second sensitivity at third time to the first sensitivity at a fourth time, wherein the fourth time is after the photodetector receives return light based on the first light pulse. The example method may also include emitting, by the optical ranging system at the fourth time, a second light pulse.

摘要： Systems, methods, and computer-readable media are disclosed for context aware verification for sensor pipelines. Autonomous vehicles (AVs) may include an extensive number of sensors to provide sufficient situational awareness to perception and control systems of the AV. For those systems to operate reliably, the data coming from the different sensors should be checked for integrity. To this end, the systems and methods described herein may use contextual clues to ensure that the data coming from the different the sensors is reliable.

摘要： Devices, systems, and methods are provided for rapid laser recharging. A pulse emitting device may include an emitter to emit pulses, a first capacitor to provide pulses to the emitter, a second capacitor to charge the first capacitor, a first gate and a second gate to control the flow of current to the capacitors and the emitter, and a power supply configured to supply energy associated with the pulses. When the first gate is open, the first capacitor charges a first pulse of the pulses. When the first gate closes, the emitter emits the first pulse. When the first gate opens, the second gate closes and the second capacitor charges the first capacitor with a second pulse of the pulses. When the second gate opens after the second capacitor charges the first capacitor with the second pulse, the first gate closes and the emitter emits the second pulse.

摘要： Systems, methods, and computer-readable media are disclosed for multi-detector LIDAR and methods. An example method may include emitting, by a light emitter of a LIDAR system, a first light pulse. The example method may also include activating a first light detector of the LIDAR system at a first time, the first time corresponding a time when return light corresponding to the first light pulse would be within a first field of view of the first light detector. The example method may also include activating a second light detector of the LIDAR system at a second time, the second time corresponding a time when return light corresponding to the first light pulse would be within a second field of view of the second light detector, wherein the first light detector is configured to include the first field of view, the first field of view being associated with a first range from the light emitter, and wherein the second light detector configured to include the second field of view, the second field of view being associated with a second range from the light emitter.

摘要： Systems, methods, and computer-readable media are disclosed for closed-loop control of a motor in a LIDAR system over a wireless power interface using data feedback over a unidirectional data communications interface. An example method may include receiving, by a controller on a first portion in a LIDAR system, from a second portion including a second motor, and over a unidirectional data communication interface, data associated with the second motor, wherein the second portion is configured to rotate relative to the first portion. An example method may also include providing, over a wireless power transfer interface, to the second portion, and based on the data, a power signal, wherein the power signal is used to provide power to the second motor.
