    摘要: A transmitter is provided which simultaneously transmits waveforms such as with different data rates. These transmissions are modulated (e.g. phase modulated) onto quadrature channels of a common carrier, and are then combined. The resulting composite modulated waveform is upconverted to RF, power amplified, split and routed to separate ports for transmission. The transmitted signals are then received, downconverted and demodulated to produce the original signals.

    摘要: A set of independent pseudonoise (PN) component codes greater than two are combined in a manner which produces one or more I and Q uncorrelated orthogonal pairs of resulting combined PN sequences. At least two of the component codes in a resulting combined PN sequence are combined in a manner which produces an overall imbalance of ones and zeros in the binary expression of the resulting combined PN sequence so that the resulting composite code has a partial correlation with a predetermined one of the PN component codes. In the preferred embodiment, three component codes are combined to produce uncorrelated orthogonal pairs of composite codes wherein at least one of the pairs of composite codes is produced to have a partial correlation with one or more of the component codes.

    摘要: A novel digital variable rate clock synthesizer is provided with a novel fractional-N digital phase locked loop. The all digital phase locked loop employs a digital input signal to a phase comparator which has a second input coupled to a digital control oscillator through a divide by N or a divide N+1 circuit. The digital output of the phase comparator is coupled to an error accumulating circuit which has a phase correction input signal from a fractional register and an associated accumulator. The output from the error accumulator is coupled to a pair of detectors for generating phase and frequency error detection signals which are digitally coupled to the control input of the digital control oscillator to provide a variable frequency output selected by the value of N and N+1.

    摘要: A method and system is disclosed for generating and detecting variable sequence PN codes. PN-Code sequence changes based on varying interceptor threat levels are generated at a rate fast enough to avoid exploitation while maintaining a reasonable correlation search window. The PN code sequence is phase shifted by N-chips based on the severity of the threat environment. A synchronized receiver demodulates the PN encoded signal by correlating over every possible phase of the PN code sequence. The receiver includes first and second correlators and threshold detectors adapted to detect PN signals with varying PN code sequence changes.

    摘要: Doors, especially exterior doors are installed in a building long before the construction is finished. Many doors utilize multipoint lock assemblies or mortise locks, these doors typically have expensive hardware that needs to be installed in order to open, use or lock these doors. Continued use and handling of this hardware results in damage to the same. For this reason, the inventive concept includes low cost handles that can easily be installed and can be used over and over again. The low cost hardware consists of low cost handle that are passed through existing lock mechanisms within the door. The low cost handles include a grommet on one side of the door that will be inserted into an existing opening in the door as sealant against dirt and debris. Also included on the handle is a compressible tube on another side of the handle that acts to reduce any play within the temporary mechanism. The handles are so constructed that the doors can be operated from both sides of the doors, one side only, or none at all.
