Abstract: Bits are assigned to channels of a discrete modulation communications system. A first set of channels and a second set of channels are selected from a plurality of channels in the communications system. The first and second set of channels are selected in order to re-assign one or more bits from the first set of channels to the second set of channels so as to cause a performance characteristic of one or more channels in the communications system to improve.

The actuator includes a connecting rod with a pin hole formed therein. The sliding mechanism includes a track, a slider and a switching pin. The slider includes an axial hole and slidably moves back and forth in the track. The switching pin can be inserted through or removed from the axial hole and the pin hole so that the cutting device can perform either a linear direction or an oval trace cutting in a coil spring winding machine.

Abstract: A method of forming a silicon-on-insulator semiconductor device including providing a substrate and forming a trench in the substrate, wherein the trench includes opposing side walls extending upwardly from a base of the trench. The method also includes depositing at least two insulating layers into the trench to form a shallow trench isolation structure, wherein an innermost of the insulating layers substantially conforms to the base and the two side walls of the trench and an outermost of the insulating layers spans the side walls of the trench so that a gap is formed between the insulating layers in the trench. The gap creates compressive forces within the shallow trench isolation structure, which in turn creates tensile stress within the surrounding substrate to enhance mobility of the device.

Abstract: A demodulator (10) converts television signals to video baseband signals and audio baseband signals including stereo signals representing a right channel signal value, a left channel signal value and a pilot signal having an amplitude. A DSP (60) recursively finds a coefficient value for scaling that keeps the pilot signal amplitude within a range of values, there by improving baseband signal quality, such as stereo separation of stereo signals within the baseband signals.
