The sensor assembly includes a duct extending from a first end to a second end, the first end of the duct being open to an environment external to the chamber and the second end being fluidly connected to the chamber. The duct includes a first portion at the first end, a second portion at the second end, and a middle portion between the first portion and the second portion. The middle portion extends downward from the first portion, and the second portion extends upward to the second end. | 2022-08-25 |
20220268893 | ROTATING COMPACT LIGHT RANGING SYSTEM - A light ranging system including a shaft having a longitudinal axis; a light ranging device configured to rotate about the longitudinal axis of the shaft, the light ranging device including a light source configured to transmit light pulses to objects in a surrounding environment, and detector circuitry configured to detect reflected portions of the light pulses that are reflected from the objects in the surrounding environment and to compute ranging data based on the reflected portion of the light pulses; a base subsystem that does not rotate about the shaft; and an optical communications subsystem configured to provide an optical communications channel between the base subsystem and the light ranging device, the optical communications subsystem including one or more turret optical communication components connected to the detector circuitry and one or more base optical communication components connected to the base subsystem. | 2022-08-25 |
20220268894 | SENSOR HOUSING WITH PARTICLE BLOCKING FEATURE - 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. | 2022-08-25 |
