Abstract: An infrastructure-controller for an infrastructure. The infrastructure-controller configured to: send a ranging-scheduling-signal to a key, wherein the ranging-scheduling-signal comprises timing-information for a subsequent ranging operation; and activate one or more ranging nodes associated with the infrastructure, for receiving a key-ranging-signal from the key, at an infrastructure-node-start-ranging-time based on the timing-information. The ranging-scheduling-signal has a frequency in a first RF frequency range. The key-ranging-signal has a frequency in a second RF frequency range.

Abstract: 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.

Abstract: The disclosure relates to a range-classifying-module for a radio receiver, the range-classifying-module configured to: receive a signal representative of a chirp from a transmitter, determine the presence of one or more pulses in the received signal; and classify the receiver as either proximal to or distal from the transmitter based on: one or more characteristics of the one or more pulses; in addition to a time-of-arrival of the one or more pulses.
