摘要： An alarm device for an automatic garage door includes a detecting circuit for producing a single negative pulse signal when a detector detects an opening motion of said garage door, an alarm controlling circuit for receiving said single negative pulse signal and producing an alarm signal, a "normal function" detecting circuit connecting to a garage door opening machine for producing a "normal opening" signal when said garage door is normally opened by said garage door opening machine, which is then changed to a "shut off alarm" signal provided to said alarm controlling circuit for preventing the production of said alarm signal, an alarm generating circuit for generating an alarm when said alarm signal is received, and a transformer circuit for providing low voltage for said alarm device. Accordingly, the alarm device for an automatic garage door can provide a warning alarm when said garage door is forced to open or damaged by bandits or burglars. However, as long as the residents operate a normal remote control or in-house switch of said garage door to open or close it, said garage door will be opened and closed as usual (with no alarm).

摘要： A multi-channel circuit having respective channels powered through transformers having primary windings connected in series allows substantially equal constant currents to be provided through all channels by cross-regulation while only a single channel need be monitored and controlled. The variation in current between channels is generally small and largely insensitive to imbalances between voltages on loads due, for example, to different numbers of LEDs in series connected strings in illumination devices and can be further reduced by inverse coupling between inductors in respective channels. Efficiency is improved through reduction in the number of stages of the constant current source since the respective channels provided both DC-to-DC conversion and constant current regulation.

摘要： A gate structure includes a gate control housing, a gate member and a control system. The control system includes a first and a second connector. The second connector is detachably attached on the moving object, and includes a signal generating module. The first connector and the second connector are communicated through a predetermined radio frequency signal. The gate member is operated between a closing position and an opening position, wherein in the closing position, a distance between the first and the second connector is larger than a preset connecting distance and the gate member is closed for blocking access to the restricted area, wherein in the opening position, a distance between the first connector and the second connector is within the preset connecting distance and the gate member is actuated to move for allowing access to the restricted area by the moving object bearing the first connector.
