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 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 system includes a printed circuit board (PCB). The PCB includes a radio frequency (RF) circuit that includes a plurality of circuit modules and signal trace lines. Each circuit module is electrically connected to at least one other circuit module by a signal trace line. The system includes a via fence comprising fence walls having at least two materials laminated using a printed wire board (PWB) process. The fence walls include a plurality of vias. The fence walls form a plurality of free-form RF isolation chambers, each chamber includes chamber walls that surround each circuit module outside of the PCB. The embodiments also include a method of manufacturing and/or isolating the system or components of the system.
