Abstract: A system and method for a door is disclosed. The system includes a frame magnetic lock assembly mounted to a door frame, and a door magnetic lock assembly mounted to a door for receiving inductively transferred power from the frame magnetic lock assembly. The door system also includes a door electronics subsystem mounted to the door that includes a power management system that provides power to the door from the inductively transferred power, and charges an energy storage element at the door from the inductively transferred power. The power management system provides power to the door from the energy storage element when the inductively transferred power is not available at the door, such as when the door is open, and resumes providing power to the door from the inductively transferred power once the inductively transferred power is restored. Once restored, some of the inductive power recharges the energy storage element.

Abstract: A system and method for a door system is disclosed. The system produces an inductive power transfer signal and modulates the inductive power transfer signal. The system also encodes data within the modulated inductive power transfer signal and transmits the signal at a door frame of a door. At the door, the system receives the modulated inductive power transfer signal and extracts data from the received signal, and transduces the received signal into a door power signal. The system also supports secure data transfer by encrypting the encoded data at the door frame and decrypting the extracted data at the door. As a result, the modulated inductive power transfer signal between the door frame and the door provides a secure wireless data transfer channel for configuring components at the door and/or displaying data at the door, while also providing power to components at the door.

Abstract: A door system and method for a door system is disclosed. A door body of the door system carries access control system components such as access readers, request to exit devices, and possibly magnetic lock systems, in examples. In embodiments, other devices carried by the door body include detection devices that detect physical phenomena, an interactive display, a door controller, and a power management system. The power management system provides a source of power to the other devices carried by the door body.

Abstract: A load control system includes a power supply, a load controller coupled to a load, and a supply controller. The load controller receives a first power having a first current level from the power supply, and uses the first power to cause a plurality of resistors to output a plurality of pre-defined codes. The supply controller receives the plurality of pre-defined codes, evaluates an output condition based on the plurality of pre-defined codes, and causes the power supply to output a second power having a second current level greater than the first level responsive to the plurality of pre-defined codes satisfying the output condition.

Abstract: An access control reader device integrates a touch pad in proximity to a radio frequency identification (RFID) antenna. A touch pad circuit board includes the RF antenna having a physical aperture and the capacitive touch pad positioned at least partially within the physical aperture of the RF antenna. This configuration allows the RFID reader to detect RFID tags in proximity to the capacitive touch pad. In order to prevent interference, such as the formation of eddy currents, the sensors of the touch pad are in the form of interrupted loops.
