摘要： A parking inventory management system includes a sensor apparatus with a plurality of magnetometers each configured to respectively generate a magnetic signatures of a vehicle as it drives across the sensor apparatus. A computing device is associated with the sensor apparatus and compares the magnetic signatures of the vehicle generated by each of the plurality of magnetometers to the magnetic signatures of the vehicle generated by each other magnetometer of the plurality thereof so as to determine a direction of the vehicle. A match between the magnetic signature of the vehicle as generated by at least two of the plurality of magnetometers indicates that the direction of travel of the vehicle is along a direction between those two of the plurality of magnetometers. A speed of the vehicle is derived as a function of a time difference between points of peak similarity between matching magnetic signatures of the vehicle.

摘要： Disclosed herein is a device and method for validating users, such as for entry into a given area. The method includes transmitting a plurality of access control tokens from an access control system to a portable device, and detecting proximity a user portable device associated with one of the plurality of access control tokens to the portable device. A symbolic representation of the access control token associated with the user portable device is generated by and displayed on the portable device. Selection of the displayed symbolic representation is accepted at the portable device. The access control system is notified of selection of the displayed symbolic representation, thereby indicating identification of a user associated with the access control token symbolically represented by the symbolic representation. The venue symbolic representation includes at least one pictograph.
