  • Patent number: 6504491
    Abstract: In a simultaneous multi-data stream transmission method and apparatus a first signal is transmitted at a fixed repetition rate from a first transceiver device (14). A second transceiver (33) then receives and demodulates the information embedded in the first signal and transmits a second signal back to the first transceiver device (14). The first transceiver (14) then receives and demodulates the information embedded in the second signal and modifies the repetition rate to another rate. A wireless receiving device (10) detects the another repetition rate of the transmitted first signal and takes action dependent on the designed application.

  • Patent number: 6456927
    Abstract: A spectral method, and corresponding system, for knock detection includes acquiring (603) spectral energy associated with vibration caused by a knocking condition from a running engine. Preferably, a sampled data system (105) acquires the spectral energy by converting an output from an accelerometer (101) into data samples (103) in a digital form. Then from the acquired spectral energy, a knock variable is derived from magnitudes of spectral components, representing a characteristic of a combustion chamber located within the running engine. In a preferred embodiment the knock variable is derived from magnitudes of spectral components related by ratios corresponding to Bessel function coefficients. The preferred embodiment includes a Digital Signal Processor (109) applying a Fast Fourier Transform method (503) to estimate a spectral content used to determine the knock variable. Then, a knock indication is provided (509) when the knock variable exceeds a magnitude of a predetermined threshold (507).

  • Patent number: 6300899
    Abstract: A fixed site data-aided system and method of GPS signal acquisition from a plurality of broadcasted GPS signals includes lengthening a pre-detection integration interval so that weak signals can be detected by operating coherently on captured signals. Coherency is ensured by relying on the predictability of the satellite signal's data pattern. To speed up both the real-time and off-line correlation process a reduced code replica search space is derived dependent on a reference code phase delay and reference Doppler shift (417), and optionally local time (509) received from a fixed position reference site. Also, the off-line correlation process can be run at a speed significantly faster than the real-time correlation process. A position fix can be either computed locally or remotely at the fixed position reference site.

  • Patent number: 6295024
    Abstract: A data-aided system and method of GPS signal acquisition from a plurality of broadcasted GPS signals includes receiving (401) the GPS signals and providing a digitized signal. Then, a first portion (407) of the digitized signal is correlated to a code replica and a real-time code phase delay is determined. A capture start time is determined (411) dependent on a Time Of Arrival (409) based on the determined real-time code phase delay. Next, a second portion of the digitized signal is captured into a memory (413) commencing coincident with the determined capture start time. Then the second portion of the digitized signal is extracted from the memory and correlated to the code replica (411) to determine an off-line code phase delay. A position fix is calculated (417) and includes the off-line code phase delay.

  • Patent number: 6151551
    Abstract: The present invention provides an assessment, in real-time, of the integrity of the positioning solution and navigation sensors used to support an Emergency Calling System (ECS) that integrates positioning and cellular phone technology. This integrity information is used, via a warning light displayed to the driver, to indicate when the system will not support Emergency Calling to the accuracies required. The present invention discusses that at least two types of warnings may be generated and provided to the user. The first being an indication that the positioning accuracy will no longer support Emergency Calling. The second being an indication that a sensor or subsystem of the Emergency Call positioning system is malfunctioning and should be serviced as soon as possible whereby such a malfunction may lead to eventual failure of the system.

  • Patent number: 5956945
    Abstract: A method and apparatus converts time-resolved sensor signals into transfer functions and/or cumulative transfer function signals which can be attained by computation means such as by using Fast Fourier Transforms. A signal, as a means to assess catalyst performance such as a signal based on sensing oxygen concentration or air to fuel ratio or hydrocarbon concentration in motor vehicle exhaust in accordance with the present invention is in the time domain and has multiple components at different frequencies. The use of Fast Fourier Transforms isolates the various spectral densities which arise from different frequency components of the complex time domain signal. Cross spectral density function and power spectral density function are used to determine the transfer function. The analysis has been found to be substantially independent of operating conditions. The transfer function and cumulative transfer function have been found to be a precise indication of the catalyst performance.
