  • Patent number: 6343364
    Abstract: A method and device is disclosed for generating a local clock signal CLK1X (172) from Universal Synchronous Bus downstream-received differential signals DM and DP carrying the downstream received bit-serial signal. The method and device does not require the use of a crystal or resonator. Counters (312, 310, 305, 301) are used to determine a number of periods of a free-running high frequency clock signal (164) contained within in a known number of bit periods of the downstream received bit-serial signal (146). The counter values are divided by the known number of bit periods of the received bit-serial signal (146) to determine a bit period of the received bit-serial signal (146). The local clock signal (172) may be phase-locked with the received bit serial signal (146). The local clock period is updated on an ongoing manner by downstream known received traffic.

  • Patent number: 6145243
    Abstract: An insect trapping device generates its own insect attractants of carbon dioxide (CO.sub.2), heat and water vapor through catalytic conversion of a hydrocarbon fuel in a combustion chamber. The hot insect attractants generated in the combustion chamber are diluted and cooled to a temperature above ambient temperature and below about 115.degree. F. by mixing with air, and then the mixture is exhausted downward through the exhaust tube. A counterflow of outside air is drawn into the trap though the suction tube that concentrically surrounds the exhaust tube. Biting insects are captured in a porous, disposable bag connected to the other end of the suction tube. A thermoelectric generator, including thermoelectric modules coupled to the combustion chamber generate power for fans that provide the exhaust flow and the suction flow. Additional chemical attractants may be used with the device to make the trap even more effective.

  • Patent number: 6058206
    Abstract: A pattern recognition device having modifiable feature detectors (28) which respond to a transduced input signal (26) and communicate a feature activity signal (30) to allow classification and an appropriate output action (70). A memory (40) stores a set of comparison patterns, and is used by an assigner (66) to find likely features, or parts, in the current input signal (26). Each part is assigned to a feature detector (28[m]) judged to be responsible for it. An updater (42) modifies each responsible feature detector (28[m]) so as to make its preferred feature more similar to its assigned part. The modification embodies a strong constraint on the feature learning process, in particular an assumption that the ideal features for describing the pattern domain occur independently. This constraint allows improved learning speed and potentially improved scaling properties.

  • Patent number: 5926150
    Abstract: A compact, broadband antenna derived from the inverted-F antenna configuration is disclosed. The tapered inverted-F antenna (TIFA) is able to generate high intensity electric fields with a physically small package size, making it particular useful for electromagnetic compatibility testing applications. This antenna derives its broadband characteristics from the combination of a number of unique features. The TIFA utilizes radiating elements that are broadband planar frames or planar sheets. The planar frames provide extended performance at low frequencies and may also include an interior lattice structure of various configurations. The novel use of triangular or "bowtie" elements for the feed and shunt elements of the TIFA provides extended performance at high frequencies. When suitably configured and properly matched to a log-periodic dipole array, the antenna is capable of providing high intensity electric fields with a very wide useful bandwidth.
