The system comprises at least one laser scanner configured to perform one or more range and intensity scans of an area around the autonomous vehicle, and a geo-location unit comprising one or more global positioning system sensors and inertial navigation system sensors. The system also includes at least one processor in operative communication with the laser scanner and the geo-location unit.

Abstract: In one embodiment, a node comprises a plurality of IEEE 1394 subnet interfaces for communicating over a plurality of IEEE 1394 buses. Each of the plurality of IEEE 1394 subnet interfaces comprises a respective IEEE 1394 physical layer and IEEE 1394 link layer for communicating over a respective one of the plurality of IEEE 1394 buses. At least the IEEE 1394 physical layers for the plurality of subnet interfaces do not share hardware. The node further comprises at least one programmable processor that executes software that comprises common network layer functionality that interacts with all of the plurality of IEEE 1394 subnet interfaces and routes IEEE 1394 data packets among the plurality of IEEE 1394 buses.

Abstract: In one embodiment, a system comprises a plurality of nodes and an IEEE 1394 bus. Each of the plurality of nodes comprises at least one IEEE 1394 interface for communicating over the IEEE 1394 bus. The plurality of nodes communicates over the IEEE 1394 bus in accordance with a rooted, half-binary tree topology. In another embodiment, a node comprises an IEEE 1394 interface to communicate over an IEEE 1394 bus. The node encapsulates logical data packets into IEEE 1394 data packets and maps a traffic class associated with each logical data packet to an IEEE 1394 class of service for the IEEE 1394 data packet into which that logical data packet is encapsulated.

Abstract: A system for communicating with RFID tags is disclosed. The system includes at least one RFID tag and a mobile RFID reader operable to interrogate the at least one RFID tag. The system also includes a first fixed RFID reader operable to interrogate the at least one RFID tag, the first fixed RFID reader configured to receive a request to interrogate the at least one RFID tag from the mobile RFID reader and configured to interrogate the at least one RFID tag based on the request from the mobile RFID reader. Additionally, the mobile RFID reader is configured to send a request to interrogate the at least one RFID tag to the first fixed RFID reader.

Abstract: Methods and apparatus for determining geo-locations. The geo-location system of one embodiment includes two or more angle determination devices and a location determination device. Each angle determination device is mounted on top of a tower. The towers are positioned a distance from each other. Each angle determination device is adapted to automatically determine the angle of incident of a received signal and transmit a determined angle signal containing the determined angle. The location determination device is adapted to automatically use spatial triangulation techniques on received determined angle signals to provide location information.

Abstract: A method to dynamically schedule communication between a master and slaves in a variable slave population in a master-slave wireless network. The method includes receiving a first interrogation phase command signal from the master, transmitting a response signal to the master responsive to the first interrogation phase command signal after a current time interval, the current time interval based on a current time slot selection, receiving an acknowledgment list from the master responsive to the transmitted response signal, determining whether the current time slot selection matches a master-filled time slot based on the acknowledgement list, and modifying an affinity value based on the determination.
