WIRELESS TRANSMITTING/RECEIVING SYSTEM, WIRELESS RECEIVING DEVICE AND WIRELESS TRANSMITTING/RECEIVING METHOD
A wireless transmitting/receiving system includes a transmitter, a first directional receiver, a camera, a storage device and a processor. The transmitter is disposed on a target object and transmits a wireless signal. The first directional receiver is disposed with respect to an entry/exit boundary. The first directional receiver receives the wireless signal and generates a first received signal strength indication. The camera captures an image of the entry/exit boundary. The storage device stores a mapping table of target object location and received signal strength. The processor is electrically connected to the storage device and determines a location of the target object and a moving direction of the target object with respect to the entry/exit boundary according to the image and the mapping table of target object location and received signal strength.

Dynamically modifying collision avoidance response procedure in autonomous vehicles
A computer-implemented method for controlling a vehicle comprises: receiving tracking data associated with a surrounding environment of the vehicle; detecting, based upon the tracking data, an object in the surrounding environment of the vehicle; determining a location of the object; determining, based on navigation assistance data, whether the location of the object is at least partially within a classified area in the surrounding environment; and configuring a control system of the vehicle to: initiate, based upon determining that the location of the object is not at least partially within the classified area, a first collision avoidance response procedure for responding to the object; and initiate, based upon determining that the location of the object is at least partially within the classified area, a second collision avoidance response procedure for responding to the object, the second collision avoidance response procedure different from the first collision avoidance response procedure.
METHOD AND SYSTEM FOR DYNAMIC REASSIGNMENT OF AN IDENTIFICATION CODE IN A LIGHT-BASED POSITIONING SYSTEM
In a positioning system, a mobile device can detect a transmission from one of a number of lighting devices to obtain an identification (ID) label or code of each lighting device. The mobile device uses the detected ID code for a lookup in a self-stored or remotely stored table that associates lighting device location information with ID codes, to obtain an estimate of mobile device position. To mitigate against hacking by a third party detecting the ID codes and observing locations to compile its own lookup table, the disclosed examples dynamically alter the assignments of particular ID codes to the lighting devices, while minimizing potential disruption of position determination service for mobile devices due to the changes to ID code assignments.
