Abstract: A system for remotely retrieving sensed conditions at one or more building components. The building components are remote or numerous so that a wireless collection of the sensed conditions provides a significant benefit to a builder or building operator. A remote transceiver sends a wireless signal to a building component. The building component includes an onboard transceiver. At least some of the energy from the transmitted wireless signal is received by the onboard transceiver, sent to a storage device, and stored therein. The stored energy is used to operate a sensor for sensing an onboard condition. The onboard condition is then wirelessly transmitted by the onboard transceiver back to the remote transceiver to be displayed.

Abstract: A compressor assembly having a high velocity muffler system which produces a particle-free compressor pump feed while reducing noise output from the compressor assembly during compressing operations. The high velocity muffler system is maintenance-free and comprises an inertia filter. The compressor assembly uses a method for producing a compressor pump feed and reducing noise during compressing operations by processing a gas through the high velocity muffler system which has an inertia filter and a muffler chamber to produce a compressor pump feed which can be compressed by a pump assembly.

Abstract: An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

Abstract: A heat transfer interface is provided for radio-frequency resonator cavity filters used in vacuum environments such as are encountered by spacecraft and satellites. The heat transfer interface may include a thermally conductive structure that encircles or partially encircles a tubular structure of the resonator cavity filter and heat transfer legs that extend from positions that are on opposite sides of the thermally conductive structure and at approximately the same distance from a support surface to the support surface. The heat transfer legs and the thermally conductive structure may be made from a material or materials having a thermal conductivity of 350 W/(m·K) or greater.
