Abstract: A monitoring system is configured to monitor an environment within an enclosure of a heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system. The monitoring system includes a sensor configured to acquire data indicative of an environmental parameter value within the enclosure. The monitoring system also includes a controller configured to receive the data from the sensor, to determine occurrence of a thermal event within the enclosure based on the data, and to instruct a circuit breaker of the HVAC&R system to transition to a fault configuration in response to determining the occurrence of the thermal event.

Abstract: A cooking oven and method of use includes a housing defining a cooking chamber with a cooking surface extending there through. A plurality of radiant emitter plates are arranged along an inner surface of the housing, preferably in strips or arrays, and directed toward the cooking surface. Each strip or array of radiant emitter plates may be independently controllable from each other. In addition, a distance between the plurality of radiant emitter plates and the cooking surface may be adjustable.

Abstract: A one piece, double gland, quad lobe design gasket system for use in a projection system that redundantly seals in the liquid present in a coupler supporting a projection lens in alignment with a projection optical signal generation device (e.g., a Cathode Ray Tube). The coupler defines a cooling chamber between said projection lens and said projection signal generating device and is filled with liquid in order to transport the optical signal between the projection optical signal generation device and projection lens while minimizing contrast distortion. In order to prevent leaking from the cooling chamber between the coupler and projection signal generation device, an improved sealing system is used by providing two separate channels in the coupler and using the integral double gland, quad lobe gasket. Each gland is placed in a corresponding groove in the coupler thus creating two separate lines of seal that keeps the liquid in the coupler from leaking out.

Abstract: A bubble trap for use in a projection system that reduces distortions caused by bubbles that occur in the coupler supporting a projection lens in alignment with a projection optical signal generation device (e.g., a Cathode Ray Tube). The coupler defines a cooling chamber between said projection lens and said projection signal generating device and is filled with liquid in order to transport the optical signal between the projection optical signal generation device and projection lens while minimizing contrast distortion. The bubble trap is an optical blocking system that is responsive to the angle of the coupler in the projection product and prevents the light from the optical signal path from striking the bubbles in the liquid in the coupler.
