Abstract: A cooling system may include a housing including an inlet; an outlet; a duct assembly between the inlet and the outlet; and at least one fan located to direct airflow from the inlet, through the duct assembly, and out the outlet; the duct assembly including: a first duct having an entrance facing the at least one fan and an exit normal to the entrance; a second duct having an entrance facing the at least one fan and an exit normal to the entrance; a central passage for receiving airflow from the first duct exit and the second duct exit; a third duct having an entrance fluidly coupled to the central passage; a fourth duct having an entrance fluidly coupled to the central passage; and a plurality of heat sinks located in the third and fourth ducts.

Abstract: Provided in some embodiments is an uninterruptable electrical power supply system. The system includes an electrical power distribution network (having a consumer side network coupled to one or more electrical loads that consume electrical power and a utility side network that supplies electrical power to the consumer side network), a primary power source (coupled to the utility side network, and that supplies electrical power to the utility side network for supply to the consumer side network), a secondary power source coupled to the utility side network, and a terminal between the consumer side network and the utility side network. The secondary power source supplies backup power to the utility side network (in response to a power shortage on the utility side network) and sinks surplus power from the utility side network (in response to a power surplus on the utility side network).

Abstract: A temperature sensor including a housing and a temperature sensing element at least partially disposed in the housing. A particulate media, which may include a blend of differently sized particles, is disposed in the housing and at least partially surrounds the temperature sensing element. The particulate media may entrain oxygen to avoid a reducing atmosphere in said housing.
