  • Publication number: 20050258999
    Abstract: A receiver circuit including an oscillator, a mixer coupled to the oscillator, a switch coupled to an output of the mixer, and an envelope detector coupled to the oscillator, such that the envelope detector generates a timing signal for actuating the switch based on the envelope of a signal produced by the oscillator. In one exemplary embodiment, the receiver circuit may be used as part of a radar based sensor system.

  • Patent number: 6937108
    Abstract: A method and apparatus for producing a modulation scheme usable in conjunction with information transmission and reception via waveforms, such as electromagnetic waves. The modulation scheme is usable for such purposes as resolving range ambiguities and overcoming fading and interference problems via use of offset signals that vary in frequency over time (e.g., chirp signals), which spread the signal over a larger bandwidth. The method includes coding a symbol signal onto a split data stream containing a reference signal (e.g., a chirp), to which a time delay has been applied, then recombining the split streams to produce a composite waveform. The method can also include demodulating a composite received waveform by applying a reference signal to the waveform and then band pass filtering the waveform into discrete symbol data. Apparatus and systems are also provided for performing the method.

  • Patent number: 6917327
    Abstract: A method for transmitting a radar signal comprises the step of transmitting a series of pulses, each of the pulses being separated in time by an interpulse period, and each of the pulses in the series being modulated in accordance with a different character of a first code

  • Publication number: 20050134388
    Abstract: The invention is directed to a system for electromagnetic communications that includes a semiconductor die; at least one amplifier on the die to amplify an input signal and generate an output signal; and an active bias control component on the die for adjusting biasing of the amplifier so that the amplifier is operable in a plurality of frequency bands. In one embodiment, a PCS band and W-CDMA power amplifier may be integrated on the same power amplifier die, and different output power requirements may be addressed by the use of an Si DC-DC converter. Such a converter may provide efficiency enhancements to the overall system through the use of dynamic bias control under active power control situations from the network. In addition, the converter may be used in a voltage up-converter state that allows a W-CDMA optimized power amplifier to operate at PCS frequencies and output power levels.

  • Patent number: 6758370
    Abstract: A dispensing mechanism is provided for flat faced products. The products are supported in a storage chute between a first upright wall and a second upright wall, stacked one on top of another. The products are supported in the chute by a support surface and a first tongue. Products are dispensed by retracting the first tongue allowing a lowermost product to fall onto a second tongue. The first tongue is advanced to be under the next highermost product in the chute. The second tongue is then retracted allowing the lowermost product to fall onto the support surface and pass through a discharge opening. In a further embodiment, flat faced products are stacked vertically side-by-side on a slightly inclined floor. The products move horizontally to one side to be dispensed. A tongue and a moveable stop are mounted at that side. The spacing between the tongue and the stop is generally equal the thickness of the product.
