Abstract: An optical measurement system includes a first light source configured to emit a first light pulse toward a target, a second light source configured to emit a second light pulse toward the target, a first detector, a second detector, and a processing unit. The processing unit is configured to determine a plurality of temporal distributions of photons included in the first light pulse and the second light pulse and detected by the first detector and the second detector after the photons are scattered by the target. The processing unit is further configured to determine, based on the plurality of temporal distributions, a distance between the first light source and the second detector.

Abstract: An RNSS based street light controller pluggable into a standard electrical interface of a street light for drawing power and controlling a lamp of the street light eliminates the need for photosensors, wiring terminals and related components and yields a street light controller with modest installation and configuration requirements and robust performance and failure recovery characteristics. In some embodiments, the RNSS based street light controller comprises an RNSS receiver, a first electrical interface and a lamp controller, wherein the first electrical interface is adapted to couple with a second electrical interface of a street light and the lamp controller is adapted to regulate a supply of power to a lamp of the street light via the first electrical interface based at least in part on information received by the RNSS receiver.

Abstract: An RNSS-based lane-level vehicle tolling method and system for a roadway having at least one managed traffic lane and at least one unmanaged traffic lane, and on-vehicle equipment for use therein, overcome lane identification limitations of RNSS-based tolling and achieves lane-level tolling through explicit lane identification. In some embodiments, a vehicle transmits a lane presence indication (LPI) to indicate to off-vehicle toll processing whether the vehicle is currently in a managed or unmanaged traffic lane. In other embodiments, on-vehicle toll processing uses lane identification information locally to determine whether the vehicle is currently in a managed or unmanaged traffic lane.

Abstract: RNSS controller having a Radio Navigation Satellite System (RNSS) receiver and adapted to exert time- and location-dependent control over at least one function of a wall-powered electrical appliance in which the RNSS controller is integrated, and methods of use thereof. Such an RNSS controller in some embodiments comprises an RNSS receiver and a signal controller adapted to generate control signals based at least in part on information received from the RNSS receiver and provide the control signals to a function controller adapted to use information in the control signals to control at least one function of the appliance.

Abstract: A management system for a traffic lane achieves congestion management objectives by dynamically predicting future vehicle density in a traffic lane and assigning to a requesting user a time slot for entering the traffic lane selected independent of any user requested time and based at least in part on a current prediction about future vehicle density in the traffic lane. The current prediction is based at least in part on predicted trajectories of vehicles, which are determined in turn based at least in part on actual trajectories of vehicles.

Abstract: A radio navigation satellite system (RNSS) automatic timer for regulating a flow of wall power is adapted to determine time and position information based at least in part on signals received from RNSS satellites, determine an operational state as a function on the time and position information and regulate a flow of power from a wall power source as a function of the operational state. Through judicious integration of a RNSS receiver into an automatic timer, the need for a user to enter time, date, and position information is advantageously reduced or eliminated outright. The need for a backup battery to maintain the clock state in the event of a power failure is also eliminated.

Abstract: A thin client intelligent transportation system wherein geospatial roadmaps and map matching systems are maintained in roadside nodes and are more fully exploited. The thin client approach offers significant advantages over thick client approaches that rely on on-vehicle maps and map matching systems, including reduced complexity of on-board equipment and elimination of map integrity issues. The thin client approach also offers significant advantages over systems wherein the vehicle is required to access maps and map matching systems in real-time from a remote data center, including the ability to meet the low latency requirements for many vehicle safety applications. The present invention in some embodiments has added advantages in that it exploits roadside maps and map matching systems in revenue generating applications that are not directly related to passenger safety.

Abstract: An improved video distribution system for the “on the go” consumer, such as the business traveler or hurried leisure traveler. In one aspect, the invention provides a video distribution system comprising a video distribution facility within a travel departure zone having video content files stored therein and one or more access units within one or more travel departure terminals of the travel departure zone, wherein each access unit is communicatively coupled with the video distribution facility via a respective wired connection and has one or more respective wired ports each adopted for short-term communicative coupling with a mobile electronic device to which one or more requested video content files stored in the video distribution facility is downloaded via the wired port for playback on the device at least in part after the device has been communicatively decoupled from the wired port.

Abstract: The present invention, in a basic feature, provides search, selection and charge methods for a video distribution system for the “on the go” consumer, such as the business traveler or hurried leisure traveler. A video content distribution method in one aspect comprises receiving from a mobile electronic device via a wired port a request for identification of available video content, transmitting to the mobile electronic device via the wired port an identification of available video content, receiving from the mobile electronic device via the wired port a selection of video content from the available video content, receiving from a payment card scanner associated with the wired port payment information for the selected video content and transmitting to the mobile electronic device via the wired port a video file including the selected video content.
