System and Method for Providing Communication Over Inductive Power Transfer to Door

Content Provider	The Lens
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.

Claim	A door system, comprising: a modulator that modulates an inductive power transfer signal; an inductive power transmitter mounted to a door frame that transmits the modulated inductive power transfer signal; an inductive power receiver at a door that receives the modulated inductive power transfer signal, with the inductive power receiver being moved away from the inductive power transmitter when the door is opened with the inductive power receiver then no longer receiving the modulated inductive power transfer signal from the inductive power transmitter; and a door power management system, including: a demodulator that extracts data from the door modulated inductive power transfer signal; and a power conditioning circuit that converts the inductive power transfer signal into a door power signa The system of claim 1 , wherein the door power management system further includes a filter that filters the door modulated inductive power transfer signal prior to the demodulator extracting the data from the door modulated inductive power transfer signa The system of claim 1 , wherein the door power management system further includes an energy storage element that the power conditioning circuit charges with the door power signa The system of claim 1 , wherein the door power management system further includes an energy storage element that supplies power to the door when the inductive power transfer signal is interrupted. The system of claim 1 , further comprising a door controller at the door that receives the data extracted by and sent from the demodulator and is powered by the door power signa The system of claim 5 , further comprising a WiFi transceiver on the door that provides data communications for the door controller. The system of claim 5 , further comprising a door position sensor at the door indicating an open and/or closed state of the door to the door controller. The system of claim 5 , further comprising a display at the door that receives the data sent from the door controller and is powered by the door power signal, wherein the display presents the data within the display. The system of claim 1 , further comprising a door control module at the door frame that provides the data to the modulator, wherein the modulator encodes the data into the modulated inductive power transfer signa A method for providing information to a door, the method comprising: producing an inductive power transfer signal; modulating the inductive power transfer signal; transmitting the modulated inductive power transfer signal at a door frame; receiving the modulated inductive power transfer signal at a door; no longer receiving the modulated inductive power transfer signal at the door when the door is opened; extracting data from the door modulated inductive power transfer signal at the door; and converting the inductive power transfer signal at the door into a door power signa The method of claim 10 , wherein extracting the data from the door modulated inductive power transfer signal at the door comprises demodulating the door modulated inductive power transfer signal to obtain the data. The method of claim 10 , further comprising filtering the door modulated inductive power transfer signal at the door prior to extracting the data from the door modulated inductive power transfer signa The method of claim 10 , further comprising charging an energy storage element at the door with the door power signa The method of claim 10 , further comprising an energy storage element at the door supplying power when the inductive power transfer signal is interrupted. The method of claim 10 , further comprising a door controller at the door receiving the extracted data in response to demodulating the door modulated inductive power transfer signal, the door controller being powered by the door power signa The method of claim 15 , further comprising a WiFi transceiver on the door providing data communications for the door controller. The method of claim 15 , further comprising a door position sensor at the door indicating an open and/or closed state of the door to the door controller. The method of claim 10 , further comprising providing data that is encoded into the modulated inductive power transfer signa The method of claim 10 , further comprising presenting the data at a display at the door. The method of claim 10 , further comprising encrypting the data and encoding the encrypted data into the modulated inductive power transfer signal at the door frame. The method of claim 10 , further comprising decrypting the data after extracting the data from the door modulated inductive power transfer signal at the door.
