Abstract: Apparatuses, methods and systems for monitoring vehicle parking occupancy are disclosed. One method includes intermittently receiving, by a wireless node, a wireless signal from a vehicle sensing device, wherein the vehicle sensing device transmits the wireless signal upon sensing a change in vehicle occupancy of an associated parking location, wherein the wireless signal includes a vehicle sensing indicator, wherein the vehicle sensing indicator indicates whether the vehicle sensing device senses vehicle occupancy of the associated parking location, measuring a signal quality of the intermittently received wireless signal over time, correlating the measured signal quality of the intermittently received wireless signal over time with the vehicle occupancy indictor, and identifying errors in the vehicle sensing indicator based on the correlating of the measured signal quality of the intermittently received wireless signal over time with the vehicle occupancy indictor.

Abstract: Apparatuses, methods and systems for an event-triggering apparatus are disclosed. One embodiment of the apparatus includes a sensor element operative to sensing a magnetic field, and apparatus control circuitry, wherein the apparatus control circuitry receives a representation of the sensed magnetic field. The apparatus control circuitry is operative to sense a deviation in the sensed magnetic field greater than a predetermined threshold, and trigger an event after sensing the deviation of the sensed magnetic field greater than the predetermined threshold.
