Abstract: A real-time commercial vehicle weight loading system is disclosed. The system employs a number of vehicle weight sensors, configured to provide vehicle weight data for a respective zone of the vehicle. The system may also utilize at least one cargo weight sensor to provide weight data of not-yet loaded cargo. A system controller is in communication with the weight sensors and is configured to, upon receiving cargo to be loaded information, send an indication of optimal cargo placement including identifying the cargo to be loaded, the location on the vehicle the cargo is to be loaded, and monitoring the loading of the vehicle. This same system may also provide total vehicle weight and broadcast real-time vehicle weights when pinged by a query device, which will allow for uninterrupted transit of the vehicle and cargo. This system may also provide data for improved vehicle stability.

Abstract: A mobile sensor calibration apparatus that is operable to be mounted to the side of a service vehicle to perform calibrations outside of a workshop environment. The mobile sensor calibration apparatus may further comprise platform members to provide an even surface for a subject vehicle having sensors needing calibration. In some embodiments, the mobile sensor calibration apparatus may be compacted and stored in the service vehicle during transportation.

The calibration assessment system may comprise configurable components useful to adapt the assessment operation to specifications of different makes and models of vehicles or different sensor arrangements. The calibration assessment system may comprise one or more autonomous functions to automatically perform the assessment operation with minimal user involvement.

Abstract: A vehicle telematics system operable to assess the operating condition of a vehicle, receive information about assets nearby, and predict a desired transaction for the vehicle at one or mare of the nearby assets. The vehicle telematics system may comprise a processor operable to consult a history of past telematics communications and vehicle operations to make a prediction of a desired transaction.

Abstract: An optical sensor calibration apparatus in the form of a wheel clamp. The wheel clamp apparatus is configured to determine a center point of a wheel of a vehicle, and to provide a measurement reference with respect to the center point. The measurement reference may be used to position other apparatuses in an optical sensor calibration system configured to calibrate an optical sensor of the vehicle.

Abstract: A storage server for efficiently retrieving data from a plurality of disks in response to user access requests. The server comprises a plurality of processors coupled to disjoint subsets of disks, and a custom non-blocking packet switch for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.

Abstract: A rate generator for generating a plurality of different frequencies that represent video requests in a video on demand (VOD) system. The rate generator comprises a plurality of parallel groups, each group comprising a phase accumulator module having a plurality of phase accumulators, a phase increment model having a plurality of phase increment registers, and an adder, coupled to the phase accumulator module and the phase increment module. The adder sums the phase increment value from the phase from the phase increment module and the output of the phase accumulator module and provides the value back to the phase accumulator module. When the sum reaches a pre-determined value, the adder resets and generates a pulse at a frequency dependent on the phase increment and the sampling frequency. In addition, a method for deriving the rate generator architecture is also provided.

Abstract: A digital information distribution system having a plurality of nodes that are connected to one another by counter-rotating data paths. Each node comprises a ring terminal that selects data packets from the data paths for use by the node and passes the remaining data packets to neighboring nodes. The data paths communicate data using asynchronous serial interface packets that transport video data or IP data.

Abstract: An internal combustion engine with an interior annular surface. A rotary piston mount rotates within an engine block interior space. Several spherical pistons are urged radially outwardly from the rotary piston mount by an urging means, and move in a radial reciprocating motion within the rotary piston mount. A gas-producing means produces an expanding gas. The gas drives the spherical pistons and the rotary piston mount rotationally along the interior annular surface of the engine block.
