Patent number: 10135288Abstract: Example wireless power transfer systems and methods are described. In one implementation, an electronic control module is configured to generate a signal to be communicated to a transmitter coil. A driver module configured to receive the signal and compensate for any degradation in signal quality is electrically coupled to the electronic control module. The driver module is further coupled to the transmitter coil. A receiver coil, wirelessly electrically coupled to the transmitter coil, is configured to receive a wireless charging signal from the transmitter coil. The implementation also includes an electronic lock module electrically coupled to the receiver coil. The electronic lock module receives the wireless charging signal from the receiver coil and uses the wireless charging signal to charge a rechargeable battery electrically coupled to the electronic lock module.Type: GrantFiled: September 29, 2016Date of Patent: November 20, 2018Assignee: FP Wireless LLCInventor: Theodore D.

Patent number: 9876387Abstract: Example systems and methods are described that wirelessly charge a rechargeable battery associated with a lock. In one implementation, a rechargeable battery is electrically coupled to an electronic lock module associated with a door corresponding to a door frame. An electronic control module associated with the door frame and physically separate from the electronic lock module generates a wireless charging link between the electronic control module and the electronic lock module. The electronic control module transmits a charging signal to the electronic lock module via the wireless charging link, and the electronic lock module uses this charging signal to charge the rechargeable battery. The implementation also includes a lock associated with the door that can be locked or unlocked by the electronic lock module.Type: GrantFiled: June 30, 2017Date of Patent: January 23, 2018Assignee: FP Wireless LLCInventor: Theodore D.

Patent number: 9876386Abstract: Example wireless power transfer systems and methods are described. In one implementation, a rechargeable battery is electrically coupled to an electronic lock module. An electronic control module that is physically separate from the electronic lock module generates a wireless charging link between the electronic control module and the electronic lock module. The electronic control module transmits a charging signal to the electronic lock module via the wireless charging link, and the electronic lock module uses this charging signal to charge the rechargeable battery. The transmission frequency of the charging signal can be varied over a predetermined frequency range by a numerically controlled oscillator.Type: GrantFiled: January 27, 2016Date of Patent: January 23, 2018Assignee: FP Wireless LLCInventor: Theodore D.

Patent number: 8680966Abstract: A method, apparatus and system for radio frequency identification provides a modulated illumination signal containing a sequence of bits configured to illuminate a radio frequency identification (RFID) tag, The illumination signal is received at the RFID tag, rectified to generate a wake signal for waking a processor which is subsequently powered by a battery. The received illumination signal is sampled and subjected to a thresholding process. Mobile telephone band interference is countered by correlating the sampled illumination signal to determine its bit sequence and then correlating the bit sequence against a predetermined key. An identification signal from the RFID tag is sent in response to a match.Type: GrantFiled: November 13, 2012Date of Patent: March 25, 2014Assignee: FP Wireless, LLCInventors: Theodore D. Geiszler, Paul G. Saldin, Eric W. Lofstad
