  • Method and device of generating time-varying preamble sequence and pseudorandom noise (PN) binary sequence in direct sequence spread spectrum (DSSS) communications
    Patent number: 8254362
    Abstract: Embodiments of the disclosure provide methods, apparatus, and articles allowing two nodes to communicate in a slot-based direct sequencing spreading communication system. Both a preamble sequence and a payload data spreading PN sequence are generated from the Time of Day and a given user code. Generated sequences are synchronized between two communicating nodes to allow slot-based DSSS communication to take place. Generated sequences also change dynamically from slot to slot to provide waveform security.
    Type: Grant

  • Method and system for optimizing audio imaging in an automotive listening environment
    Patent number: 5113447
    Abstract: An audio system having an improved sound field by generating a center audio channel from left and right stereo channels. The center channel is preferably generated by summing the left and right channels, and then filtering the resulting output. The center channel signal is also combined with the left and right channel signals to remove a portion of the monophonic information from the left and right channels thereby maintaining a constant level of monophonic information in the sound field.
