    Abstract: A luminous signalling device comprises a body made of transparent synthetic material, basically in the form of a plate having two larger faces set opposite one another, at least one of which carries an image. A plurality of LED devices of the SMD type which emit white light is coupled externally to at least one of the walls that define the peripheral edge of the aforesaid plate body. The arrangement is such that the rays of white light coming out of the LED devices undergo multiple total reflections within the plate body, which thus functions as a light guide. In areas corresponding to selected areas of the image, the face of the plate body is made up of diffusing optical elements designed to diffuse outwards the rays of light that are incident on said areas within the body.

  • Patent number: 6359564
    Abstract: A system is disclosed for indicating the status of a person relative to a workspace. A motion detector senses the entry and exit of the person through a entryway of the space and distinguishes the difference between the person's presence when moving and when stationary. An indicator automatically displays a constant green light to announce the person's presence, a flashing green light when the telephone is being used, a flashing amber light for short duration absences, a constant amber light for long duration absences and an intermittent red light and beeper for emergencies. A controller houses a preprogrammed microprocessor, a communications link and three illuminated buttons corresponding in color to the lights of the indicator and functioning in tandem with them. The green button activates the “Do not disturb” display, the amber button the long duration absence display and the red button the emergency alarm.

  • Patent number: 5774039
    Abstract: A programmable doorbell controller for the operation of a doorbell. In a preferred embodiment, an audible announcement is recorded and stored by a doorbell control module using speech controller integrated circuitry. A self-contained remote module may interface with the doorbell control module by means of a wireless intercom system. When the doorbell actuation means is actuated, the remote module transmits a tone or signal that is received and detected by the doorbell control module. In response, the doorbell control module activates an internal speech controller circuitry to generate a playback of a stored audible announcement. Similarly, a visitor can easily respond by actuating a recording actuation means to activate a microphone for generating a responsive audible message that can be transmitted to the control module for encoding and storage. In this manner, the visitor's audible message is encoded, recorded and stored by the speech controller integrated circuitry of the control module for playback.

  • Patent number: 5757267
    Abstract: A wireless audible indication system comprising a transmitter and a receiver. An embodiment of the transmitter includes a crystal oscillator which produces a signal having a predetermined audio frequency. A duty cycle limiting circuit limits the duty cycle of the oscillator signal to be less than 25%. The limited duty cycle signal is applied to a radio frequency oscillator to produce an amplitude modulated radio frequency signal. An embodiment of the receiver includes a superregenerative detector which provides wide band detection of transmissions about a carrier frequency. A signal processing circuit formed by a cascade of a crystal filter stage, an amplifier/comparator stage, and a detector stage, processes the signal from the superregenerative detector. A sound generator integrated circuit, which generates an audible signal indicative of reception of a transmitted signal, is coupled to the signal processing circuit.
