  • Patent number: 6240294
    Abstract: An Adaptive Position Transmission Algorithm (APTA) for mobile radio device where position information is required, using any transmission medium such as high frequency (HF), very high frequency (VHF), ultra high frequency (UHF), Satellite Communications (SATCOM), etc. A mobile radio device employing the APTA provides accurate and automatic position reporting and thus, in a tactical environment improves situation awareness and reduces the probability of fratricide. A mobile radio device employing the APTA also reduces the number of options available to the user thereby simplifying the operation thereof while improving overall performance in most applications. The APTA accomplishes this by monitoring position, time and radio network parameters to determine when stand alone messages will be transmitted. The APTA factors radio network loading with movement and periodic thresholds.

  • Patent number: 6111860
    Abstract: There is disclosed a voice/data protocol for use with half duplex digital radios. The protocol modifies the X.21 HDLC protocol which is widely employed in the transmission of data for digital radios. The X.21 protocol utilizes a control "C" and an indicate "I" signal. In the steady state in conventional systems, both the C and the I leads are "off". When either a DTE or DCE requires service, the units set their C lead to the "on" condition. The opposite end detects the request for service on the I lead and when communications occur, sets the C lead to the "on" condition. When both the DTE and DCE have send and detected "on" conditions on their C and I leads the circuit transfers to the data transfer state and is ready to proceed to data synchronization. In the present protocol, the C signal is defined as a push-to-talk transmit request to the radio. The I signal is defined as a radio busy. When the I signal is asserted by the radio, the radio is busy transmitting voice, receiving voice or receiving data.

  • Patent number: 6052406
    Abstract: There is disclosed an improved frequency hopping synchronization and tracking system for bit syncing and frame syncing a digital data signal as transmitted by a radio transmitter. A detection means responsive to incoming data samples representative of the phasing signal portion of the digital data signal partitions the data samples into alternating first and second sample sequences and correlates the samples against a frequency hop modulation code reference sequence to provide an initial data signal detection. A post-detection means responsive to the initial detection and to the frequency hop modulation code reference sequence correlates the incoming data samples and compares the spectral power of the correlated data samples to a threshold value to provide bit sync of the detected data signal.

  • Patent number: 6052423
    Abstract: There is disclosed a bit sync search and frame sync search system operative with a digital data signal as transmitted by a digital radio transmitter. The bit search is implemented by detecting a predetermined phasing signal which is incorporated in the digital signal and which has a repetitive bit pattern of ones and zeroes. The phasing signal is first detected by providing an in-phase and quadrature component signal and correlating those signals to provide an output signal indicative of the bit pattern in the phasing signal. After the phasing signal has been provided and an oscillator associated with a receiving apparatus is compensated according to the detected phasing signal, a tracking mode is entered, whereby a frame signal is captured and the system generates histograms of data bit transitions for producing an error signal indicative of the difference of the transmitted clock rate and the sampling portion of a received bit.

  • Patent number: 5946132
    Abstract: A telescopic sight which can be used for either nighttime or daytime operation and is particularly adaptable for use on weapons ranging from rifles to anti-tank weapons.A first embodiment includes a single objective and two parallel light paths, one for day viewing and one for night viewing. The objective forms the beginning of the night path. Separating mirrors transmit light from the objective along the night path and reflects light from the objective to the day path. The night path includes an image intensifier assembly. A mirror at the end of the night path reflects the light from the image intensifier assembly to a beamsplitter/combiner on the day path. The beamsplitter/combiner transmits the light from the day path and reflects the light from the night path along the same path to an ocular assembly for viewing.A second embodiment of the telescopic sight is similar to the first embodiment but contains two objective lens assemblies for collecting light, one for the night path and one for the day path.
