  • Patent number: 8001860
    Abstract: A vehicle sensor system consisting of video, radar, ultrasonic or laser sensors, oriented to obtain a 360 degree view around the vehicle for the purpose of developing a situation or scene awareness. The sensors may or may not have overlapping field of views, or support the same applications, but data will be shared by all. Orientation of the sensor to the vehicle body coordinates is critical in order to accurately assess threat and respond. This system describes methods based on measuring force and rotation on each sensor and computing a dynamic alignment to first each other, then second to the vehicle.

  • Publication number: 20100197322
    Abstract: An inband signaling modem communicates digital data over a voice channel of a wireless telecommunications network. An input receives digital data. An encoder converts the digital data into audio tones that synthesize frequency characteristics of human speech. The digital data is also encoded to prevent voice encoding circuitry in the telecommunications network from corrupting the synthesized audio tones representing the digital data. An output then outputs the synthesized audio tones to a voice channel of a digital wireless telecommunications network.

  • Patent number: 7283567
    Abstract: Network delay is determined in order to synchronize a clock in a mobile station with a reference clock. Tones are generated that represent a sequence of bits in a synchronization flag. The tones are sampled beginning at a selected sample start time. The sampled tones are demodulated to identify the bit values in the synchronization flag. The demodulator is synchronized with the sampled tones in the synchronization flag by shifting the sample start time until the samples generate an optimum synchronization value. A reference time is then identified according to the optimum sample start time.

  • Publication number: 20060268930
    Abstract: A multiprocessor system used in a car, home, or office environment includes multiple processors that run different real-time applications. A dynamic configuration system runs on the multiple processors and includes a device manager, configuration manager, and data manager. The device manager automatically detects and adds new devices to the multiprocessor system, and the configuration manager automatically reconfigures which processors run the real-time applications. The data manager identifies the type of data generated by the new devices and identifies which devices in the multiprocessor system are able to process the data.

  • Patent number: 6920129
    Abstract: The invention provides for conversion of latitude and longitude to an addressing scheme that supports current TCP/IP (Ipv4) and future addressing (Ipv6/Ipng) requirements. More specifically, it allows a decentralization of the unicast point to a device on the hosted network. Geographical Internet Protocol (geoIP) addressing will facilitate anycast routing schemes in which the nearest node has a statically assigned geoIP. Geo-routing and network management become a function of the geoIP address.

  • Patent number: 6771629
    Abstract: Methods for determining a system latency of an audio call path of a voice communications network, and for synchronizing a remote unit (108) with a reference oscillator of a reference station (102) involve transmitting a reference signal (106) over the audio call path from the reference station (102) to the remote unit (108), where a reply signal (112) is generated and transmitted back to the reference station (102) over the call path after a preselected reply delay interval (tdet). A round-trip time difference (tRT) is used to determine total system latency, which is then taken into account in synchronizing the remote unit (108) with the reference oscillator. The reference and reply signals (106, 112) are generated as audio-frequency signals resembling human voice sounds to avoid destructive attenuation by the voice communications network. One embodiment includes a wireless telephone unit having an on-board SPS receiver.

  • Patent number: 6681121
    Abstract: A wireless telecommunication device, such as a cell phone, is coupled to a source of digital data which may comprise a GPS receiver. In one embodiment, a GPS receiver and inband signaling modem are integrated into the cell phone battery pack. A pushbutton on the battery pack is actuated by a user to trigger selected events such as formulating location data in the GPS receiver, encoding the location data in the IBS modem and inserting the resulting audio frequency tones into the voice channel of the cell phone for transmission over the voice channel of a digital, wireless telecommunications network.
