Abstract:
A system, apparatus, and method are provided for controlling equipment operable by a plurality of operators. A control state evaluation device is configured to evaluate a control state of an equipment control. A signal detection device is configured to detect if a signal associated with an operator of the equipment control is present. A process controller is configured to activate a first equipment function if the signal from the equipment control is present, and is configured to activate a second equipment function if the signal is not present.
Abstract:
A data messaging system includes a satellite radio receiver configured to receive a message including a message identifier and two or more filter criteria and to process the message to generate a processed message according to the message identifier and the two or more filter criteria. A telematic unit is coupled to the satellite radio receiver. The telematic unit is configured to provide positional data to the satellite radio receiver. A body control module is also coupled to the satellite radio receiver. The body control module is configured to provide vehicle information to the satellite radio receiver. A display, coupled to the satellite radio receiver, is configured to display the processed message.
Abstract:
Methods and apparatus are provided for insuring that a motor vehicle is being operated by an authorized operator. The apparatus includes an electronic control unit (ECU), an engine immobilizer unit, and a shared encryption key. The ECU generates a challenge by combining the output of a pseudo-random number generator and the output of a somewhat random number generator and cycling the combined number through a linear feedback shift register. The ECU sends the challenge to the immobilizer unit where it is encrypted with the shared key and sent back to the ECU as a response. The ECU uses the same key to encrypt the challenge and compares the encrypted challenge to the response. If the response matches the encrypted challenge, engine operation is enabled.
Abstract:
A vehicular display system having a camera for producing a video signal and a display device for displaying the video signal. The display device includes an integrity check to detect a defective video signal and alert the driver if a defective video signal has been detected.

Abstract:
Apparatus is provided for an electronic vehicle storage system. The apparatus includes a vehicle electrical infrastructure, a vehicle communications network coupled to the vehicle electrical infrastructure, a controller coupled to the vehicle electrical infrastructure via the vehicle communications network, and a data storage device coupled to the controller and configured to store multimedia files. The controller is configured to communicate with the vehicle electrical infrastructure. The data storage device includes an embedded database containing a list of multimedia file content. The controller is further configured to access the embedded database and associate a recognized multimedia file with a multimedia file content from the list of multimedia file content.
Abstract:
System, methods, and apparatus are provided for wireless vehicle-to-vehicle sharing of multimedia data. The system includes a data storage device configured to store multimedia data packets transmitted by a system broadcast, a processor coupled to the data storage device and configured to determine a non-received group of multimedia data packets based on the stored multimedia data packets of the system broadcast, and a transceiver coupled to the processor. The transceiver is configured to receive multimedia data packets transmitted from the system broadcast and multimedia data packets transmitted from a system vehicle in response to the request signal. The method includes the steps of determining non-received multimedia data packets based on a system broadcast in a first wireless protocol, and requesting multimedia data packets of the non-received multimedia data packets in a second wireless protocol from system vehicles.
Abstract:
Apparatus and methods are provided for wirelessly broadcasting large multimedia files to vehicles. The apparatus includes a vehicle-based receiver configured to wirelessly receive at least one group of encoded data packets at a data rate based on a number of concurrently broadcasted groups of encoded data packets, a decoder coupled to the data storage device, a data storage device coupled to the receiver, and a media playback unit coupled to the data storage device. The group of data packets corresponds to at least a portion of a multimedia content, and each of the data packets contains at least a portion of the multimedia content. The data rate is based on an average vehicle operation duration and/or a probability of occurrence of the average vehicle operation duration. The decoder is configured to assemble at least a portion of the multimedia content from the first data file upon the data storage device receiving a pre-determined number of data packets. The data storage device is configured to store the group of data packets and assembled multimedia content. The playback unit is configured to play the assembled multimedia content.
Abstract:
Methods and apparatus are provided for generating route instructions on a turn-by-turn navigation system in a vehicle. Turn instructions can include a turn icon as well as visual and audio prompts. The turn-by-turn navigation system includes special routing features, such as “Where am I”, “Verification”, “Stop by”, pre-set destinations, and time-restricted road routing. The turn-by-turn navigation system can generally be produced more economically than a typical premium system having a full complement of costly features, such as a color map display. Moreover, the turn-by-turn navigation system can be configured with only those features deemed most useful to a broad-based market segment, in order to further reduce manufacturing costs.
