Abstract: A method for distributing an audio instruction from a manager site at a client site in a distributed audio system having a plurality of client sites, a generalized audio instruction for playback of audio at the client sites is received via user input at the manager site. The generalized audio instruction includes a plurality of labels which are global in the audio system and are indicative of a time schedule category, an audio zone category, and an audio source category. Pre-defined information which associates the plurality of labels indicative of the time schedule, audio zone, and audio source categories with client site specific identifiers of a time schedule, an audio zone, and an audio source, respectively, is accessed for each of client sites. The generalized audio instruction is adapted using the pre-defined information to generate a specialized audio instruction for each of the one or more client sites.

Abstract: A method for audio calibration of an audio device is provided. The method comprises: registering, by a microphone, a representation of an audio signal; processing, by a data processing unit, the registered representation of the audio signal into feedback image data; displaying on a display, the feedback image data; capturing, by a camera, the feedback image data displayed on the display; altering a setting affecting audio of the audio device based on the feedback image data captured by the camera. A system for audio calibration of an audio device is further provided.

Abstract: Described is a method for registering and executing instructions in a video capturing device and to a door station.

Abstract: Optical modulators and switches for use in telecommunications systems are disclosed having solid-state crystalline optical material comprised of III-V, II-VI, and IV semiconductor nanocrystals embedded in a polymer matrix. In a preferred embodiment, the crystalline material comprises CdSe crystals sized at less than 5.8 nm in diameter and more preferably at less than about 4 nm in diameter and advantageously embedded in poly(vinyl pyridine). The crystalline material sandwiched between two electrodes defines an optical modulator. In one preferred embodiment, the crystalline material with ten-percent crystal embedded in a polymer will exhibit with an applied voltage of 100V, a differential absorbance spectra (.DELTA.A) of about 50 cm.sup.-1 at wavelengths of about 610 nm and a differential refractive index (.DELTA.n) of about 10.sup.-4 at wavelengths of about 625 nm.
