  • Patent number: 6768777
    Abstract: A method is provided for estimating a number of digital subscriber line nodes (220, 230) required to supply, from a line supply source (200), a geographically distributed network of substantially sequentially numbered twisted pair lines with digital subscriber line service. The method comprises the steps of: storing, in number order, data entries for every twisted pair line of the network, each data entry comprising a pair number and a line length of the respective twisted pair line in relation to the line supply source (200); sorting the entries stored in the database by line length; isolating those sorted entries whose twisted pair lines have a line length greater than a predetermined maximum line length in relation to the line supply source (200); sorting the isolated entries by number; and discriminating, from the sorted isolated entries, the presence of discrete groupings of substantially contiguous entries.

  • Patent number: 6705359
    Abstract: A pressurized package of paint, additives is prepared by mixing water emulsion, stabilizers and a propellant in a pressurizable container. This pressurized container is then sold to retail stores where a water borne paint composition is injected into the pressurized container and sold directly to the end user.

  • Patent number: 6707913
    Abstract: A telephone network interface device that provides at least two drop-wire connection ports and two distribution cable ports. One drop wire port provides full bandwidth service with the second port providing telephone service only, reducing radio frequency ingress and egress magnitudes. Bridging options allow limited bandwidth or full bandwidth communication between distribution cable ports.

  • Patent number: 5349606
    Abstract: Circuit for recovery of a plurality of multipath direct sequence spread spectrum signal components received over a time span, wherein the multipath signal components are components of a signal generated from digital data comprised of data bits at a data bit rate modulated by a pseudo-noise code, consisting of a sequence of chips having a chip rate greater than the data bit rate, wherein the sequence of chips is a code repetition period equal or greater than the received time span of the multipath signal components. A plurality of correlators is provided. Each correlator has a first input for coupling to the multipath signal components, a second input, and an output. A pseudo-noise code generator generates a duplicate of the pseudo-noise code. A time delayer is coupled between the second inputs of a mulitiplicity of the correlators and the pseudo-noise code generator for delaying the duplicate of the pseudo-noise code by a multiple of a time delay equal to the time of a chip duration or less.

  • Patent number: 5343495
    Abstract: Method of demodulating a signal including a plurality of time-dispersed signal components such as resulting from receiving in a multipath environment. A plurality of correlators are provided. The period of expected time uncertainty is scanned to identify the highest energy signal components. Each correlator is assigned to process one of the highest energy signal components. Each of the correlator outputs is pase corrected to compensate for carrier phase differences. The correlator outputs are coherently combined to provide a data output.

  • Patent number: 5315616
    Abstract: A correlator for processing a direct sequence spread spectrum communication system signal, wherein digital data comprised of data bits at a data bit rate is modulated by a first pseudo-noise code comprised of a sequence of chips having a pseudo-noise chip rate greater than the data bit rate, each chip having a chip period, the sequence repeating at a code period, and the pseudo-noise modulated data modulates a carrier resulting in the signal. A sampler produces digital samples of the signal. A pseudo-noise code generator produces a second pseudo-noise code replicating the first pseudo-noise code. Circuity time syncronizes the second pseudo-noise code to maximize a combined value of correlated signal energy, thereby time locking the first pseudo-noise code and the second pseudo-noise code.

  • Patent number: 5315615
    Abstract: Method of processing a direct sequence spread spectrum communication system signal wherein digital data comprised of data bits is modulated by a first pseudo-noise code comprised of a sequence of chips, the pseudo-noise chip rate greater than said date bit rate, each chip having a chip period, said sequence repeating at a code period, and the pseudo-noise modulated data modualates a carrier frequency resulting in the signal. Digital samples are made of the signal. A second pseudo-noise code replicates the first pseudo-noise code. A first correlation is made of the sampled signal and the second pseudo-noise code. A second correlation is made of the sampled signal and the second pseudo-noise code delayed by one chip period. A first correlated signal energy value represents the signal energy of the first correlation. A second correlated signal energy value represents the signal energy of the second correlation.

  • Patent number: 5313491
    Abstract: Method for indicating the end of an acquisition procedure between a transmitter and receiver in a direct sequence spread spectrum communications system. At a transmitter, a first acquisition code having a first acquisition code period and comprised of digital bits at a first bit rate is generated. The first digital acquisition code is modulated by a pseudo-noise code repeating at a pseudo-noise code period and consisting of a sequence of chips at a chip rate greater than the first bit rate, and wherein the first acquisition code period is an integer multiple of the pseudo-noise code period. A carrier frequency is modulated by the first digital acquisition code modulated by the pseudo-noise code. The carrier is modulated by the first digital acquisition code modulated by the pseudo-noise code is transmitted for a first period of time.
