Abstract: The present disclosure relates to devices, lidar systems, and vehicles that include optical redirectors. An example lidar system includes a transmitter and a receiver. The transmitter includes at least one light-emitter device configured to transmit emission light into an environment. The receiver is configured to detect return light from the environment and includes a plurality of apertures, a plurality of photodetectors, and a plurality of optical redirectors. Each optical redirector is configured to optically couple a respective portion of return light from a respective aperture to at least one photodetector of the plurality of photodetectors. Each optical redirector also has a rotational orientation relative to other optical redirectors such that the redirection paths of optical redirectors that correspond to adjacent apertures are not coplanar with one another.

Abstract: A sanitizing device includes a base, a container supported by the base, a heating element supported by the base, and a blower assembly supported by the base. The container can include a base wall, a side wall, and a hot air inlet vertically offset above the base wall. The blower assembly can be situated with respect to the heating element and the hot air inlet to direct air over the heating element and through the hot air inlet into the container.

Abstract: A toothbrush sanitizer includes at least one basket for holding a toothbrush, a housing that receives the at least one basket, and a heating element connected to the housing. The basket(s) can also accommodate a toothbrush head from a known electric toothbrush. The basket can be completely removable from the housing so that the basket can be separately cleaned from the housing. The heating element heats the toothbrush to sanitize the bristles. According to an alternative embodiment, the toothbrush sanitizer can include a first toothbrush basket, a second toothbrush basket, a housing that receives the baskets, and a heating element connected with the housing. The second basket receives the first basket.

Abstract: An air sterilizer for eliminating an associated airborne contaminant from an associated volume of air is provided. The air sterilizer includes a housing including an air inlet and an air outlet, an airflow pathway initiating approximately at the air inlet of the housing and terminating approximately at the air outlet of the housing, and an ultra-violet (UV) radiation source for producing a germicidal UV light. The UV source is disposed in the airflow pathway of the housing for exposing the associated airborne contaminant to the germicidal UV light. The air sterilizer further includes a reflecting member for increasing the exposure of the germicidal UV light to the associated airborne contaminant in the airflow pathway. The reflecting member being disposed in the housing proximal to the UV source. A power supply is provided for powering the UV source.
