Patent number: 11258480Abstract: A key fob including at least one wireless communication circuit, a power supply node coupled to provide power to the at least one wireless communication circuit, a battery node, a battery power circuit, and an inductive power circuit. The battery power circuit provides power when a battery with sufficient charge is provided. The inductive power circuit only provides power when energized with inductive power when the battery is not provided or is not sufficiently charged. The inductive power circuit may include a rectifier circuit and an inductor and may further include regulator circuitry. The inductive power circuit does not perform wireless communications thereby simplifying circuitry and operation of the key fob and a corresponding access system. Since only configured to transfer power, the inductive power circuit may be optimized for power transfer. The access system inductively couples power to the key fob when within a predetermined coupling zone distance.Type: GrantFiled: March 31, 2020Date of Patent: February 22, 2022Assignee: NXP B.V.Inventors: Wolfgang Eber, Dorian Haslinger

Publication number: 20210094509Abstract: The embodiments described herein include systems and methods for providing controlled accesses to secured devices using near-field communication signals transmitted from a mobile communication device. More specifically, the embodiments described herein determine a measure of a field strength of a near-field communication signal transmitted from a mobile communication device to determine a distance to the mobile communication device, and selectively allow access to the secured device based at least in part on that determined distance. Such a system and method can be implemented using features commonly provided on smart phones and other mobile communication devices, and as such can be used to provide a distance-based controlled access to a secured device without requiring the user to carry a separate key-fob or other specialized hardware.Type: ApplicationFiled: September 30, 2019Publication date: April 1, 2021Inventors: FRANK GRAEBER, WOLFGANG EBER

Patent number: 10427643Abstract: A system includes a first unit associated with an object and a second unit. The first unit includes a first transceiver coupled with first processing circuitry. The second unit includes a second transceiver coupled with second processing circuitry. Methodology includes establishing a bidirectional wireless communication link between the first and second units. Following establishment of the communication link, the first and second units exchange messages.

The second processing circuitry measures a second RSSI value for each of the messages received at the second unit and sends the second RSSI value in another subsequent message to the first unit. A relay attack is determined in response to the first and second RSSI values.Type: GrantFiled: July 13, 2018Date of Patent: October 1, 2019Assignee: NXP B.V.Inventors: Filippo Casamassima, Matja{hacek over (z)} Gu{hacek over (s)}tin, Wolfgang Eber
