Abstract: The present disclosure provides a sensor cleaning system that cleans one or more sensors of an autonomous vehicle. Each sensor can have one or more corresponding sensor cleaning units that are configured to clean such sensor using a fluid (e.g., a gas or a liquid). Thus, the sensor cleaning system can include both a gas cleaning system and a liquid cleaning system. According to one aspect, the sensor cleaning system can provide individualized cleaning of the autonomous vehicle sensors. According to another aspect, a liquid cleaning system can be pressurized or otherwise powered by the gas cleaning system or other gas system.

Abstract: A heat dissipation apparatus, system and method for an air circuit breaker (ACB) switchgear has at least one pair of primary contact toes constructed and arranged to connect to a terminal of the circuit breaker. A bus bar joint is connected to the primary contact toes. The heat dissipation apparatus comprises an evaporator clamped to the primary contact toes. A condenser is located at a higher elevation than the evaporator and at least two electrically isolating pipes fluidly connect the evaporator with the condenser. A dielectric fluid in the evaporator can be heated to a vapor state, with one of the pipes transferring the vapor to the condenser and the second pipe returning the condensed dielectric fluid back to the evaporator for cooling the at least one pair of primary contact toes.
