  • High performance frequency tuning with low cost synthesizer
    Patent number: 5301366
    Abstract: A communication system and a method for using an approximating frequency synthesizer with frequency correction by digital signal processing (DSP) means to provide a radio transmitter or receiver with rapid high resolution tuning capabilities. A user selects a frequency upon which he wishes to transmit or receive information. An approximating synthesizer is used to provide an RF injection frequency. A radio controller interprets the user selected frequency and determines the closet available approximating synthesizer frequency. The controller commands the approximating synthesizer to the determined available frequency and calculates the difference in the determined available frequency and the user selected frequency. The calculated difference or error is passed on to the DSP for correction during frequency mixing in a single or multiple step process.

  • Data compression method for telemetry of vibration data
    Patent number: 4908785
    Abstract: Vibrational data is compressed about 8.5 to 18 times by isolating a low frequency component from the signal, frequency analyzing the signal to obtain important frequency/amplitude data, and recombining the low frequency component with the analyzed information for efficient transmission.
