Abstract: A switching system includes: a switch including an ON state and an OFF state; and an actuator. The actuator includes: an actuation system including an actuation material that has a temperature-controllable spatial extent; a control system configured to adjust the temperature of the actuation material to control the spatial extent of the actuation material; and a driving assembly coupled to the actuation system. The driving assembly moves in response to a change in the spatial extent of the actuation material to thereby change the state of the switch.

Abstract: A light-emitting diode (LED) luminaire assembly includes a mounting module having a cavity. The luminaire assembly also includes an LED assembly coupled to the mounting module at an end of the cavity, and a driver mounted on a driver plate and configured to provide electricity to the LED assembly, the driver plate coupled to the mounting module. The luminaire assembly further includes one or more reduced thickness sections provided on a series path of thermal conduction between the LED assembly and the mounting module, to facilitate decreased conductive heat transfer therebetween.

Abstract: A high-lumen light-emitting diode (LED) luminaire assembly in a harsh and hazardous environment is provided. The luminaire assembly includes an integrated mounting module manufactured as a single piece and including a first side and a second side opposite the first side. The luminaire assembly also includes an LED assembly coupled to the mounting module at the second side of the mounting module, and a driver configured to provide electricity to the LED assembly. The luminaire assembly further includes a driver cover sized to cover the driver and coupled to the mounting module at the first side of the mounting module. The driver and the LED assembly are operable within a target peak temperature limit for the hazardous environment.

Abstract: A light device including a housing having at least one wall that defines an internal cavity. A heat sink is attached to the housing. The heat sink includes a body, a plurality of mat fins disposed about a periphery of a body, and a plurality of pin fins disposed in staggered rows on a central portion of a face of the body. The plurality of mat fins direct air in a predetermined direction to the central portion and the plurality of pin fins define a plurality of tortuous air paths along the central portion.

Abstract: A refrigerated display case includes a base. A first wall extends from the base and has a first supply air duct defined therein. A second wall extends from the base and has a second supply air duct defined therein. The first wall and the second wall define a product area therebetween. A return air duct is disposed in the product area between the first supply air duct and the second supply air duct. An evaporator coil is disposed in an equipment space defined between the product area and the base. The equipment space is fluidly coupled to the first supply air duct, the second supply air duct, and the return air duct. A first circulation fan is disposed in the equipment space proximate the first supply air duct. A second circulation fan disposed in the equipment space proximate the second supply air duct.

Abstract: In a refrigerated display case having an interior volume that is accessed through a door panel being opened from a doorframe, a frame cover is included that may reduce condensation or the power required to avoid condensation on a door panel. The frame cover is formed of a non-metallic material that provides a thermal break. The frame cover may also be formed with air pockets to further enhance the thermal break. Moreover, it may be formed to attach with an interference fit and thereby avoid fasteners. Other embodiments and features are presented.

Abstract: A refrigerated display case includes an air director that directs air with less turbulence in a resultant air curtain but also allows for the convenient removal of an air filter member by using a flexible hinge on a portion of the air deflector. Other embodiments are disclosed as well.
