摘要： The present invention provides a device for regulating an ac current circuit using a magnetic relay which is suitable for use in an incandescent lamp circuit or electric motor circuit to eliminate or reduce inrush-current. The present device comprises connecting power switch, diodes, series resistance and relay such that, after closing the power switch, an ac current first flows to a load through the series resistance for a brief time, then to the load through the contacts of the relay after a lapse of the brief time by bypassing the series resistance.

摘要： A measuring instrument, such as a densitometer, that uses an incandescent lamp as a measuring light source is provided with a control stage for energizing the light source upon switch-on to prevent overshoot of the desired luminous flux from the lamp that occurs if the final energizing voltage is applied immediately. The control stage includes an amplifier with a negative feedback network that is fed with a reference voltage via a switch. The feedback network includes a resistance-capacitance element and is responsive to closure of the switch to establish the initial lamp energizing voltage at 1-2% below its final value and to allow the voltage to rise to its final value over a period of 1 to 3 seconds.

摘要： Disclosed is a capacitance responsive and touch sensitive power control system for successively switching different loads across a power supply. The system includes a pair of bidirectional triggerable switches, such as semiconductor TRIACS, which operatively connect and disconnect different loads in series with a single power supply. These switches are alternately driven to conduction and nonconduction in a predetermined sequence by a pair of bistable flip-flops, the inputs of which are controlled by body capacitance signals applied to a common input circuit of the system. A novel threshold and delay noise discrimination network is interconnected between this input circuit of the system and the pair of bistable flip-flops and it discriminates between body capacitance signals and line noise in order to minimize false operation of the system due to line noise. In a preferred embodiment of the invention, the triggerable switches are a pair of TRIACS which respond to a predetermined sequence of conductive states of the pair of flip-flops, respectively, to provide successively higher power levels to multiple loads in response to successive body capacitance signals received at the touch signal input circuit.

摘要： A focus pluggable interface control device includes a sensor, a lens covered on the periphery of the sensor and a mounting plug electrically connected to external lamps. Optical signals passing through the lens to be focused is transmitted to the sensor. The lens is configured to collect control information of light types transmitted to the sensor in order to increase sensitivity of the sensor to receive the control information and response speed of the control information, and also expand sensing range of the sensor so as to improve user's experience. The sensor is electrically connected to the external lamp via the mounting plug so that the focus pluggable interface control device can be conveniently replaced, disassembled or installed without needing additional wires, thereby the cost of replacing the control device can be reduced.
