International Classification:

H04H 500

US Classification:

381 14

Abstract:

Two parallel signal paths carry a composite signal having a narrow-band component such as an FM station's composite signal. The first path includes a notch filter that removes the narrow-band component, such as the FM stereo pilot tone, from the composite signal and also includes a reciprocal clipper coupled to the output of the notch filter that selects peaks beyond given maximum and minimum limits from the remainder of the composite signal. These peaks are then effectively subtracted from the corresponding peaks of the composite signal in the second path and the resultant signal is used to modulate the station's carrier frequency. The resultant signal is an amplitude limited composite signal in which the narrow-band component is substantially unimpaired even though the composite signal has been amplitude limited.

International Classification:

G05F 140

US Classification:

323237

Abstract:

A light dimmer is provided in which semiconductor power devices for each of the polarities of an alternating current supply are coupled between the alternating current supply and a lamp load. In the course of varying average power supplied to the lamp load, the semiconductor power devices transition between an initial one and a subsequent other of substantially conductive and non-conductive power conditions. The duration of the transition by the power device is increased beyond the minimum possible duration to reduce generated EMI. Methods of restoring each power device to its initial condition, including during a subsequent half-cycle, are described.

International Classification:

US Classification:

323235

Abstract:

A light dimmer with semiconductor power devices coupled between an alternating current supply and a lamp load, in the course of varying average power supplied to the lamp load, transitions the power devices under load between one and the other of substantially conductive and non-conductive conditions, increasing the duration of the transition by the power device itself from the minimum possible duration to reduce generated EMI. Undesirable effects of the high current demands of cold lamp filaments are reduced by initially increasing the conductive portion of half-cycles, relative to the proportion required to produce the desired amount of average power, while avoiding transitions at phase angles that would produce excessive losses. A transition shape may be employed in this mode and in normal operation that maximizes audible lamp noise suppression for a given level of thermal losses.

International Classification:

H05B 3700

US Classification:

315317

Abstract:

A lighting system made up of a plurality of light fixtures which each produce a light beam, in which each of a plurality of varying devices, each having an input and an output, and each capable of varying at least one parameter of the light beam from at least one of the light fixtures, is responsive to a first value received at the input, where the first value corresponds to the desired adjustment of a parameter of the light beam. Each of the varying devices is also capable of generating a second value which represents status information, and transmitting the second value via the output. A controller produces the first value and sends it to an output which is coupled to the input of the varying device. A monitoring device has an input and is separate from the controller, and its input is coupled to the output of the varying device.

International Classification:

G05F 100

US Classification:

315194

Abstract:

Lamp dimmers are disclosed in which, in the course of varying average power supplied to the lamp load, the semiconductor power control devices transition between one and the other of substantially conductive and non-conductive power conditions, the duration of the transition by the power control devices themselves is increased beyond the minimum possible duration to reduce generated EMI. The dimmers disclosed provide for varying the direction, duration, shape, and phase angle of transitions.
