Abstract: Disclosed herein are system, method, and computer program product embodiments for adjusting a transmission field-of-view (Tx FoV). For example, the system includes a lidar sensor with a series of emitters. Each emitter is configured to transmit light pulses away from a vehicle along a transmission axis to form a transmission field-of-view (Tx FoV). At least one detector is configured to receive at least a portion of the light pulses that reflect off of an object within a reception field-of-view (Rx FoV) along a reception axis. A transmit optic is mounted for translation along a transverse axis and configured to intersect each transmission axis without intersecting the reception axis to adjust the Tx FoV without adjusting the Rx FoV.

Abstract: A high voltage (HV) interface housing is provided that includes an assembly of levers within the housing that detect whether or not the HV lines are coupled to the interface housing. If the HV lines are not in place, the lever assembly prevents the interface cover from being fully installed onto the interface housing, thereby preventing the HV interlock loop switch from being closed. As a result, when the HV cables are not in place, the HV interlock loop switch prevents power from being applied to the HV circuit. If, however, the HV lines are properly positioned within the interface housing, the levers of the lever assembly automatically retract, thus allowing the interface cover to be fully installed onto the interface housing. In this state, the interface cover closes the HV interlock loop switch, thus closing the HV interlock loop and allowing power to be applied to the HV circuit.

Abstract: An electronic device enclosure configured to shield against electromagnetic interference (EMI). The electronic device enclosure includes an electronic device-enclosure base and at least one laterally disposed blunt boss. The electronic device-enclosure base includes a bottom, and sides and attached to the bottom in a boxlike configuration. The laterally disposed blunt boss is configured so as to be disposed between, and to couple electrically, a side of the electronic device-enclosure base and a vertical flange of an electronic device-enclosure cover. The electronic device-enclosure base and the electronic device-enclosure cover are configurable with respect to said laterally disposed blunt boss to shield an interior space enclosed by the electronic device-enclosure base and the electronic device-enclosure cover against EMI at a resonant frequency of a slot of the electronic device enclosure.
