    摘要： The present invention involves a method for transmitting data within a specified band of allocated spectrum in a satellite digital transmission system. First a data stream (420) is encoded according to a first encoding scheme, then a second data stream (422) is generated according to a second encoding scheme. The second encoding scheme is incompatible with the first encoding scheme. The first and second data streams are transmitted at predetermined locations within the specified band, such as time slices within a time division multiplexing transmission system. The second data stream is generated by using a more efficient FEC algorithm, including turbo-convolutional, turbo-product, low density parity check, or repeat-accumulate encoders. The inventive receiver has an antenna (142) for receiving RF signals and a demodulator (144) coupled to the antenna for downconverting received RF signals into a data stream. A splitter (146, 147) then separates the data stream into first and second component data streams. A first detector (148) is coupled to the splitter, and is adapted to detect data in the first format. A second detector (149) is coupled to the splitter, and is adapted to detect data in the second format.

    摘要： The present invention involves a method and system for transmitting data in an optical or hybrid optical and RF wireless network from a base structure (10, 110, 111) including a base apparatus (120) to a target device including a target apparatus (140). The base apparatus includes a base receiver (122), a laser (126), a device for positioning a laser-emitted beam (128), and a base microprocessor (124). The target apparatus includes a target transmitter (142), a photodetector (146), and a target microprocessor (144). Once the target device comes to a rest beneath the base structure, the target transmitter communicates the presence of the target apparatus to the base receiver. A communication uplink is established between the target apparatus and the base apparatus. The base microprocessor then activates the laser and instructs a commercial laser based steering system to continually adjust the position of the laser beam in a search pattern until it illuminates the photodetector, at which time a communication downlink is established between the base apparatus and target apparatus. Data is then transmitted from the laser to the photodetector via the communication downlink at speeds of 100 Mbps to 10Gbps.

    摘要： A system and method for controlling communication modes of a personal communication device traveling in a vehicle. The system includes a communication center configured to provide communication services, a personal communication device (PCD) configured to communicate with the communication center, and a controller installed in a vehicle. The communication center is configured to selectively disable any of the PCD communication modes when the PCD is residing or traveling in the vehicle. Which communication modes are disabled may be based on a customer profile. The system and method provide a way for a parent to limit the communication modes of PCD used by their child, especially when the child is traveling in and presumably operating a particular vehicle such as the family car. The system and method may also be used by employers to limit the PCD communication modes available to employees operating company vehicles.

    摘要： A system (20) and method are provided for detecting use of RF transmit devices (e.g., cellular phones) (24) in a vehicle (10). The system (20) includes a first RF antenna (22A) for detecting signal strength of an RF signals transmit device at a first location in a vehicle (10) and a power first detector (44A) for generating a first output signal indicative thereof. The system also includes a second antenna (22B) for detecting signal strength of the RF signals at a second location in the vehicle (10) and a second power detector (44B) for generating a second output signal indicative thereof. The system further includes a signal processor (50 or 62) for processing the first and second output signals to determine the presence of an RF transmit device (24) in use in the vehicle (10) and to further determine the location of the RF transmit device (24) to determine if a driver (16A) is using the device (24).

    摘要： A satellite-based digital audio radio (SDAR) receiver buffers an audio or video data stream and obtains metadata relating to the content of the data stream either during or after the transmission of the data stream in SDAR services in which a priori information is unavailable. Based on the metadata and on a selection criterion, the receiver selectively stores portions of the data stream for subsequent use. Thus, the SDAR receiver may provide a user with functionality approximating "content on demand" capabilities of other streamed data services without the use of a priori information that is unavailable in some SDAR services.

    摘要： The present invention provides a system and method for degrading and disabling a vehicle's engine throttle. The vehicle disable system includes a throttle position sensor (220, 320, 420) that generates a throttle position signal, an electronic control module ("ECM") input (324b, 424b) connected to the ECM on which the throttle position sensor provides the throttle position signal to the ECM, and an override input (383, 483) that enables an idling signal to be transmitted to the ECM in lieu of the throttle position signal. The method of the present invention includes the steps of receiving an input signal related to the state of a driver input mechanism (534, 734), interpreting the input signal, and at least one of degrading and disabling the throttle based on the interpretation of the input signal.
