    摘要: A communications system is provided for sending and receiving information relative to a mobile unit in which a number of network channels are available through which the information can be transferred. The system includes a link selector for selecting an acceptable network channel using application requirements for the particular channel, together with channel operating parameter values. When such a channel does not become available, the link selector is also involved with recovery procedures. These network channel operating parameters include bandwidth, information transfer costs and information transfer packet loss, latency and jitter. Weighting vectors are also utilized with such channel operating parameters in determining suitability values associated with the available network channels. The link selector communicates with a link scheduler that has responsibility for determining when information should be transferred including when there should be a change in the timing of the information transfer. The link selector also receives data from a controller/monitor that obtains such dynamic data associated with selected network channel operation in connection with determining whether a switch should be made from the currently selected network channel to different network channel.

    摘要: Communication of information including data between a remote computer and a vehicle is managed and facilitated using an apparatus compatible with standardized network communication links. In one embodiment, the standardized network communication links include the Internet and a controller area network used in vehicles. The apparatus preferably includes a controller contained in the vehicle. The controller is comprised of a number of hardware and software elements including a processor. A TCP/IP stack is part of the controller for providing the necessary control in checking for communicating information, such as requests and data, over the Internet. A web server communicates with the TCP/IP stack for servicing information related requests in http format including obtaining or sending information in operative communication with the TCP/IP stack. A CGI-bin (common gateway interface-binary) communicates with the web server and acts as a link to executable software stored in program memory that is responsive to user requests. A data memory is also available for storing data in html that is accessible by the web server. A real time operating system (RTOS) is involved in task and memory management as part of the responding to requests for information. The controller is able to receive requests using a wireless device when it is in the vehicle and through a communications port when the wireless device is not in the vehicle. In another embodiment, each of the plurality of vehicle devices has an Internet address or designation associated with it.

    摘要: A cellular telephone is interconnected to a control unit via a cable. The cable contains both appropriate interdisciplinary connections for attachment to the telephone at one end and to the control unit at the other end via a universal connector. At least one contact of the universal connector is capable of producing a signal coded to identify the type of cellular telephone attached to the connector at the other end. A decoder at the control unit identifies the type of phone as by table look-up and establishes appropriate interfacing operational functions at its universal connector to properly operate with the telephone. Accordingly, the control unit can function with any of a wide variety of cellular telephones having differently configured cable connections and cable connector disciplines of contact assignments. In addition, the control unit may include circuitry for controlling a number of peripheral devices which are operable to send and receive digital data through the cellular phone unit to and from remote devices via radio frequency signals.

    摘要: A holographic recording is made on a tone wheel which is arranged to be driven by a capstan motor and capstan assembly. The holographic recording is a series of radial holograms on the tone wheel which recording is matched to the mechanical system driving the tone wheel by incorporating mechanical drive errors in the holographic recordings. The holographic recording on the tone wheel is read during subsequent operation of the motor/capstan/tone wheel assembly by a laser playback system to provide control signals for a motor energizing means to correct intrinsic drive system errors in a "sync-off-tach" type tape drive system.

    摘要: Media which stores protected content is distributed to users without the need for payment at the time of media distribution. Payment can be performed at a later time in response to which content may be enabled, and/or users may selectively pay for, and receive enablement of, content such that only portions of content on given media may be accessible at a given time. Following the first enablement of content, access rights may be expanded or otherwise changed, e.g., in response to a second payment.
