Abstract: Example embodiments relate to pulse energy plans for light detection and ranging (lidar) devices based on areas of interest and thermal budgets. An example lidar device includes a plurality of light emitters configured to emit light pulses into an environment in a plurality of different emission directions. The lidar device also includes circuitry configured to power the plurality of light emitters. Further, the lidar device includes a plurality of detectors configured to detect reflections of light pulses emitted by the plurality of light emitters. In addition, the lidar device includes a controller configured to (i) determine a pulse energy plan based on one or more regions of interest in the environment and a thermal budget and (ii) control the circuitry based on the pulse energy plan. The pulse energy plan specifies a pulse energy level for each light pulse emitted by each light emitter in the plurality of light emitters.

Abstract: This technology relates to a system for preventing particle buildup on a sensor housing. The system may include a sensor housing including a first surface, a motor, and a spoiler edge. The motor may be configured to rotate the sensor housing around an axis. The spoiler edge may be positioned adjacent to the first surface and extended away from the first surface perpendicular to the axis of rotation of the sensor housing.

Abstract: Example embodiments relate to light detection and ranging (lidar) devices having a light-guide manifold. An example lidar device includes a transmit subsystem. The transmit subsystem includes a light emitter. The transmit subsystem also includes a light-guide manifold optically coupled to the light emitter. Further, the transmit subsystem includes a telecentric lens assembly optically coupled to the light-guide manifold. The lidar device also includes a receive subsystem. The receive subsystem includes the telecentric lens assembly. The receive subsystem also includes an aperture plate having an aperture defined therein. The aperture plate is positioned at a focal plane of the telecentric lens assembly. Further, the receive subsystem includes a silicon photomultiplier (SiPM) positioned to receive light traveling through the aperture.

Abstract: This technology relates to a system for cooling sensor components. The cooling system may include a sensor which has a sensor housing, a motor, a main vent, and a side vent. Internal sensor components may be positioned within the sensor housing. The motor may be configured to rotate the sensor housing around an axis. The rotation of the sensor housing may pull air into an interior portion of the sensor housing through the main vent, and the air pulled into the interior portion of the sensor housing may be exhausted out of the interior portion of the sensor housing through the side vent.

Abstract: An example method includes making a first determination that a load of a cooling system of a vehicle is expected to increase and become greater than a capacity of the cooling system; operating, in response to making the first determination, the vehicle in a first mode where a combustion engine and an electric motor operate such that a charge level of a power supply of the vehicle increases or is maintained above a threshold charge level; making, after operating the vehicle in the first mode, a second determination that the load of the cooling system has become greater than the capacity of the cooling system; and operating, in response to making the second determination, the vehicle in a second mode where the combustion engine and the electric motor operate such that the charge level of the power supply decreases or is maintained below the threshold charge level.
