  • Patent number: 9362738
    Abstract: An intelligent control system for a high-voltage switch and a control method thereof. The control system includes a control terminal (10) and a plurality of high-voltage switches (21-1, 21-2, . . . , 21-n-1, 21-n), each of which is controlled by an executive terminal (11-1, 11-2, . . . , 11-n-1, 11-n) respectively, wherein the executive terminal is connected to the control terminal via a communication network. The executive terminal includes a current detecting module (5), an analog/digital conversion module (4), a second communication module (2), a calculation processing module (3), a first communication module (1) and a switch control module (6) which controls the switch in real-time. The current detecting module detects a line current value. The analog/digital conversion module converts the line current value into a digital current value. The first and second communication modules are for communication.

  • Patent number: 6734788
    Abstract: An electrical anti-theft device for a motor vehicle issues an audible alarm signal for a predetermined period of time in response to tampering with the vehicle which is sensed by the anti-theft device. At the end of the predetermined period of time, a strobe light is activated and operates continuously thereafter to indicate that the vehicle has been tampered with. At the same time, the electrical anti-theft device is reset so as to issue the alarm signal in response to further tampering with the vehicle. The electrical anti-theft device is incorporated in a mechanical anti-theft device mountable on a vehicle steering wheel to limit rotation thereof.

  • Patent number: 6549121
    Abstract: A battery-powered emergency signaling device including a housing which encloses a battery pack disposed for providing power to the device. The housing includes a base plate for support of the device and has a cover attached to the base plate for sealing up the device. At least one light emitting diode (“LED”) pulsed by an electronic circuit, which LED is powered by a battery within the battery pack. A race is disposed substantially about the periphery of the cover for reflecting light received from the LED. The race is formed as an integral part of the cover, which is made of clear acrylic plastic. The cover includes support members disposed between the base plate and the cover for providing strength to the device.

  • Patent number: 6154150
    Abstract: A vehicle positioning apparatus includes a projection unit mounted above a parking position in a garage or similar enclosure, and having a projector which will project a beam of visible light downwardly onto the parking position. A detection unit is positioned separately from the projection unit, and will detect a specific triggering event in order to activate the projector to emit the lightbeam. The detection unit may include a switch which is actuated upon movement of a garage door to an open position, a motion detector which actuates the projector upon detection of the movement of a vehicle towards the parking position, or an infrared beam positioned to be broken upon movement of a vehicle towards the parking position.

  • Patent number: 6107911
    Abstract: A self-contained programmable time interval alarm device that has a plurality of switches or buttons to set the alarm interval. Depending on the mode of the device, each button corresponds either to a day of the week or a numeral representing a particular time digit or number of dosages for a given time interval. In this manner, the alarm is simply programmable by actuating a sequence of buttons corresponding to the desired interval. The alarm device has a housing to which is attached a clamp supplied with jaws, into which containers of different dimensions can be clamped and held. The jaws move from a relaxed position to an expanded position and finally to a biased position as the medication container is pushed between free ends of the jaws and then pushed to enter a grasping space between the jaws.

  • Patent number: 4426639
    Abstract: A timing apparatus for holding a door open for a controlled period of time before releasing it for closure. The timing apparatus includes a switch operable to produce a switching signal. A first energizing control is coupled to the switch and is responsive to the switching signal for producing a first signal. An electromagnetic device is coupled to the first energizing control and is energizable in response to the first signal. A first timing circuit is coupled to the first energizing control and is responsive to the first signal to generate a first timing signal of predetermined duration and corresponding to the switching signal. The first energizing control is further responsive to the first timing signal thereby to remain in the state of providing the first signal for such predetermined duration. A second timing circuit is coupled to the first timing circuit and is responsive to the termination of the first timing signal to produce a second timing signal of second predetermined duration.
