20140244145 | WIRELESS VEHICLE DETECTION SYSTEM AND ASSOCIATED METHODS HAVING ENHANCED RESPONSE TIME - Embodiments of the invention include a wireless vehicle detection systems and associated methods with extended range and battery life. The wireless vehicle detection system can include a plurality of sensor pods in communication with an access point without repeaters. Embodiments of the sensor pod can include a vehicle detector controller adapted to determine the presence of vehicles and a communication controller connected to the vehicle detector and adapted to transmit data 300 feet or more to an access point, which in turns communicates with the base station. To extend the battery life of the sensor pod, the sensor pod can be adapted to detect received communication signal strength and adjust transmitting power based upon said strength to thereby conserve power. Embodiments of the sensor pod can also include a battery connected in parallel to an HLC capacitor to further extend the life of the battery. | 08-28-2014 |
20140240146 | Wireless Vehicle Detector Aggregator and Interface to Controller and Associated Methods - Embodiments of systems and methods of the present invention include efficient, reliable aggregation and transfer of one or more sensor pods detect status to the base station and then the traffic controller. An embodiment of an access point maintains a sensor state array, which is the current status of the sensor pods in communication with the access point. The access point can maintain the sensor state array in its memory and relay the sensor state array to the base station. An embodiment of a base station can use the sensor state array information to generate and update a vehicle detector array, which is the current status of all the sensor pods in the wireless vehicle detector network. An embodiment of the base station emulates one or more bus interface units and uses the vehicle detector array to relay detector information to the traffic controller periodically or when polled. | 08-28-2014 |
