摘要:
A multiple discharge tube lighting system has a plurality of gas discharge tubes positioned behind a translucent panel, within a or tube or in close proximity to each other and each tube is connected through a power supply to a dimming control circuit. The control circuit is used to change the brightness and on/off state of each tube to create the appearance of different colors when the tubes are viewed in combination using dimming and/or interleaving. The control circuit can match dimming curves, and stores, retrieves and sends power information for each tube to create displays which can be identically produced repeatedly.

An addressable lighting device and control system uses a user-actuable infrared or radio frequency operated remote control(s) to selectively or collectively generate an electronic address for the addressable lighting device on which the device will respond to all future signals from the remote control corresponding to that electronic address. The addressable lighting device has a programming mode for setting the address and a working mode for receiving control signals on the set address and correspondingly setting the desired intensity level of light. The addressable device may have the address set and changed locally (manually) or remotely using the remote control to switch modes, thereby avoiding the problems, expenses and mistakes associated with using dual in-line package (DIP) switches, binary, hex rotary switches, or thumbwheel switches normally used to set each one of the system's unit's unique address.

A safety system and method for connection of a toxic gas detector to a toxic gas producing engine, comprising an interrupt device coupled to connections to the detector and the engine, including a toxic gas signal detecting circuit and a circuit for permitting starting of the engine. In one embodiment, the permitting circuit is activated if the safety system is healthy and fully functional. Similarly, a safety system and method for connection of a toxic gas detector to a toxic gas supply, comprising an interrupt device coupled to connections to the detector and the toxic gas supply, including a toxic gas signal detecting circuit and a circuit for permitting of flow from the toxic gas supply. In both embodiments, the detecting circuit activates the permitting circuit if the toxic gas signal represents a toxic gas concentration below a predetermined level.

An addressable lighting device and control system uses a DMX protocol controller to selectively generate an electronic address for the addressable lighting device on which the device will respond to all future signals from the controller corresponding to that electronic address. The addressable device has a program mode for setting the address and a working mode for receiving control signals on the set address. The addressable device may have the address set and changed remotely using the DMX protocol controller and a remote control to switch modes, thereby avoiding the problems associated with using DIP switches to set device electronic addresses.

An assembly, system and method for adaptively monitoring and operating a lamp fixture include a power input interface, a ballast, and a lamp interface. The ballast is coupled to the power input interface for receiving the received input power and creating lamp power between a first lamp terminal and a second lamp terminal. The ballast includes a transformer having a primary winding, a first lamp powering secondary winding, and a second lamp powering secondary winding. The transformer further includes a non-lamp powering secondary or third secondary winding for detecting a ballast operating parameter and transmitting a sensed ballast operating parameter value corresponding to the detected ballast operating parameter. A sensor detects an arc current circulating through a lamp received in the lamp interface and transmits a sensed arc current value corresponding to the detected arc current. One or more output interfaces provide the transmitted sensed arc current value and transmitted sensed ballast operating parameter value to an external system communicatively coupled.

A motorized shower water diverter valve for a handheld shower is connected to a shower water inlet pipe in lieu of a conventional showerhead. A conventional showerhead is then connected to one of two valve outlets and a hose for the handheld shower is connected to the other valve outlet. The valve may be constructed as a rotary or linear type. A motor output shaft is coupled to a gear assembly to either rotate a valve core of a rotary valve or laterally displace the core of a linear valve. The gear assembly may include a slip clutch. There is also provided a control circuit for operating the motor, a wireless remote control and a sensor for enabling the control circuit to detect the position of the valve core.
