  • Publication number: 20030207222
    Abstract: A lighter is provided. The lighter includes two spaced apart nozzles. Upon manual actuation of the lighter, each nozzle produces a separate flame, and the flames intersect to produce a single flame in region spaced apart from the body of the lighter.

  • Patent number: 6631255
    Abstract: A receiver (10) for a wireless telecommunications system that provides relatively wideband signal processing of received signals without increased signal distortion so that multiple received signals can be simultaneously processed. The receiver (10) includes a specialized LNA (16), frequency down-converter (18) and ADC (20) to perform the wideband signal processing while maintaining receiver performance. The frequency down-converter (18) employs a suitable mixer (28), BPA (32), attenuator (34), and transformer (36) that are tuned to provide the desired frequency down-conversion and amplitude control over the desired wideband. The down-converter devices are selected depending on the particular performance criteria of the ADC (20). A specialized digital channelizer (22) is included in the receiver (10) that receives the digital signal from the ADC (20), and separates the signals into the multiple channels.

  • Patent number: 6488460
    Abstract: A panel insert for use with a structural panel and a fastener having a hold out mechanism. The panel insert comprises a body portion disposed within the structural panel. The body portion includes a first surface, an opposing second surface, and an aperture passing therethrough for receiving the fastener. A recessed portion opening to the second surface is provided to receive the hold out mechanism and secure the fastener to the structural panel.

  • Publication number: 20020172231
    Abstract: A time multiplexed multiple carrier transmitter includes a first data encoder that produces first transmit data and a second data encoder that produces second transmit data. In addition, the transmitter includes a digital multiplexer coupled to the first and the second data encoders. The digital multiplexer provides a transmit signal output. A transmit frequency upconverter coupled to a power amplifier and the transmit signal output provides a final upconversion (or direct upconversion) to a transmit frequency for each channel. The transmitter also includes a multiplexer control circuit coupled to the digital multiplexer through a multiplexer control input. The multiplexer control circuit produces a multiplexer control signal on the multiplex control input that selects between the first and second data encoders according to a transmit schedule. The transmit schedule determines when, at the frequency at which, the transmitter selects and transmits data from each data encoder.

  • Publication number: 20020142739
    Abstract: A multi-channel transmission system and method provide peak power smoothing without additional in-band interference. The system includes a multi-carrier waveform generator for reducing peak amplifier power required to transmit a digital multi-carrier waveform based on a plurality of digital carrier waveforms. A signal conversion system generates an analog multi-carrier waveform based on the digital multi-carrier waveform. The analog multi-carrier waveform has a center frequency and a desired gain over the original signal. A bandpass filter is coupled to the signal conversion system for restriction of the analog multi-carrier output waveform to a desired transmission bandwidth. The multi-carrier waveform generator has a nulling waveform generator coupled to a plurality of single carrier waveform modules for generating a digital nulling waveform based on the retrieved data. The nulling waveform reduces a peak power of the multi-carrier waveform and results in a reduced signal envelope.

  • Patent number: 6452520
    Abstract: A superconducting A/D converter (10) has an error correction system (70) for eliminating non-linearities in a primary quantizer (30). The converter (10) includes a primary quantizer (30), a primary SFQ counter (50), and the error correction system (70). The primary quantizer (30) generates primary SFQ pulses based on an average voltage of an analog input signal. The primary SFQ counter (50) converts the primary SFQ pulses into a digital output signal based on a frequency of the primary SFQ pulses. The error correction system (70) corrects the digital output signal based on the analog input signal and the primary SFQ pulses. Using the primary SFQ pulses to correct the digital output signal allows the converter (10) to take into account the non-linearities of the primary quantizer (30).

  • Publication number: 20020119805
    Abstract: A chilled transceiver for use in terrestrial and satellite communication systems. The chilled transceiver eliminates various problems associated with transceivers which incorporate superconducting devices. In particular, the chilled transceiver is based entirely upon conventional semiconductor technology, such as heterojunction bipolar transistor (HBT) technology formed from conventional GaAs, AlGaAs and InP materials which when chilled to temperatures down to, for example, 100° K can provide a 50% improvement in noise while trimming power losses by 20% or more at the same time. In one embodiment of the invention, the chilled transceiver is formed with a chilled receiver front end which includes a frequency diplexer, a filter, a low-noise amplifier (LNA) and a mixer, formed from conventional semiconductor technology which are housed in a refrigerator typically used for superconducting circuits.
