  • Patent number: 6875013
    Abstract: A combination lighter having dual cutting assemblies for severing the end of a cigar and punching a hole therein is disclosed. The device includes a lighter body which supports a lighter mechanism, a first cutting assembly, and a second cutting assembly. The first cutting assembly may be a guillotine style cutter having a housing which supports a moveable blade. The first cutting assembly is moveable between a closed position adjacent the lighter body, and an open position where it extends from the lighter body. The second cutting assembly may be a punch style cutter having a tubular-shaped body and a cutting end for cutting an opening in the end of a cigar. The second cutting assembly may be moveable between a retracted position, where the cutting end is substantially flush with an end of the lighter body, and an operative position where the cutting end extends from the lighter body.

  • Patent number: 6813320
    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.

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. In one embodiment, the frequency down-conversion is performed in a single down-conversion process, and the ADC (20) employs delta-sigma processing to provide digital conversion over the complete frequency band.

  • Patent number: 6771940
    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.
