Abstract: An impact sensor calibration tool, wherein an impact sensor is installed on a vehicle and in wireless communication with a processor, which analyzes data reported by the impact sensor. Specifically, the impact sensor of the present invention continuously measures two dimensional acceleration of a vehicle. Changes in vehicle acceleration create impulse data and the impact sensor reports this data to a processor. The processor performs statistical calculations on the data to identify the vehicle's normal use operation and from this, develops an impact threshold wherein impulses exceeding this threshold are identified as impacts. The impacts may be further characterized as real impacts and stored in memory for subsequent analysis.

Abstract: A mobile RFID tracking system for RFID applications includes a central data processing system, an RFID reader for reading identifications of proximately located RFID tagged items, and an RFID verifier for comparing read identifications of proximately located RFID tagged items to a predetermined list of RFID tagged items. A communicator is coupled to the RFID reader to communicate the received read identifications over a wireless interface to the central data processing system. Each mobile portal may be actuated for RFID read operations in response to information sensed concerning operation of the mobile asset/vehicle. Additionally, the central data processing system may issue instructions concerning mobile asset/vehicle operation, with those instructions communicated over the wireless interface to the mobile portal. Responsive to implementation of those instructions, the mobile portal actuates the RFID reader and compares the read identifications to a list of RFID tags that were expected to be read.

Abstract: An automated vehicle rental system with individual vehicle transmitting sensors for keeping track of vehicle mileage, fill state of vehicle fuel tank, and localized position status in a rental lot. Sensors are linked to the vehicle odometer reading and to the vehicle fuel tank float sensor with compensation for types of driving and fuel fill-ups which affect float level readings. The sensors are integrated with or are linked with communicating tags operable in a defined site for ultimate communication of stored vehicle related sensor data, vehicle location and type to a central data base for automatically completely effecting check out, charges and state of vehicle readiness for renewed rental. The transmitting sensors are adapted to avoid interference between sensors of other vehicles during multiple transmissions.
