Patent number: 11055941Abstract: An electronic control key including security check circuitry used by an inductive system to perform at least one security check to determine whether to enable authorized functions. The inductive system receives power and enables communications via an inductive link for backup operation. The security check circuitry may include battery status circuitry and distance measurement circuitry. The inductive system invokes the distance measurement circuitry to perform a secure distance check when the battery status is good, in which the inductive system enables authorized functions only when the secure distance check passes. The security check circuitry may include a motion detector for performing a motion inquiry. The motion inquiry may include detecting motion of the electronic control key or detecting a predetermined characteristic movement or a programmed motion pattern. The security check circuitry may be a button in which authorized functions are enabled only when the button is pressed.Type: GrantFiled: March 31, 2020Date of Patent: July 6, 2021Assignee: 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: 6595414Abstract: A data carrier receives an amplitude-modulated carrier signal that is amplitude modulated in dependence on data to be received. The modulated carrier signal has a high interval of high amplitude and a pause interval of reduced amplitude. The data carrier has a data processor for processing received data. The data carrier generates d.c. power from the received carrier signal and stores the d.c. power, and detects the pause interval. Upon detecting the pause interval, the data carrier generates an identification signal from the received carrier signal. The identification signal is a logic gating signal. In dependence of the identification signal, a controller causes the application of a clock signal to data processor to be inhibited.Type: GrantFiled: March 24, 1999Date of Patent: July 22, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Wolfgang Eber, Peter Thüringer
