    Abstract: This invention relates to an active brake release device attached to the exterior of a door controller, comprising: a first electromagnet, in which a sliding portion can slide to activate a sliding bar when the electromagnet is energized for magnetic excitation; a first and a second actuator, in which the first actuator is located to abut against the break release bar of the door controller, and a sliding pin of the first actuator is yielding biased in the anti-activation direction of the bar; and, the second actuator is limited by a limit means at a fixed position; a second electromagnet, which is used to release the second actuator when it is energized for magnetic excitation; a circuit, which includes a limit-switch and provides instant power to the first electromagnet during the resetting of the device; and a capacitor, which is used to temporarily supply power to the second electromagnet in unexpected electricity failure. Thus, in the instant of unexpected electricity failure, the device will actively release the brake by mechanical force, and shut off the safety door by sliding down with its own weight.

    Abstract: This invention relates to a type of safety door central release device which can be used to close the safety door automatically when electric power is disrupted. It comprises a cord that is tied to a mechanism having potential energy on one end, and extended to a far distance on the other end; a pair of crank arms of which one end molded as a grip and gripping the cord, and the other end is connected to a sliding bar, having potential energy which assists the grip in release the cord. When electric power is supplied, the sliding bar will be attracted to an electromagnet. As a result, while electric power is disrupted, the release device can immediately release the cord. Due to release of the cord, a brake for a door operator is released by means of the mechanism such that the safety door slides down and then it is closed.

    Abstract: A non-contact sensor system controls movement of a door moving in a first direction by actuation of a device. The system includes a transmitter extending a predetermined distance beyond a leading edge of the door at a first door end for transmitting a signal toward a second door end. The transmitter is attached to the door by a first moveable member which is capable of engaging a surface when the door closes and moving to a retracted position. The sensor system further includes a receiver extending a predetermined distance beyond the leading edge of the door at the second door end in alignment with the transmitter for detecting the signal, and for generating an output signal when the signal is blocked. The receiver is attached to the door by a second moveable member which is capable of engaging the surface when the door closes and moving to the retracted position.

    Abstract: An accordion fire door is provided including an accordion member having interlocking panels formed of a fire retardant or fire proof material, a guide member positioned on at least one side of the accordion member for guiding the accordion member during movement between an opened position and a closed position, end locks arranged at interconnected ends of adjacent panels for maintaining panel contact and alignment, and a releasing member connected to the accordion member for releasing the accordion member in response to a predetermined condition of at least one of heat, fire, smoke, manual initiation and a drive. The panels are self hinged along the entire interlocking sides.

    Abstract: A parking area control and management system employs a card reader, which reads identification information from a card commonly carried by a person, such as a driver's license or credit card. A record is made of the identification information upon entrance of a vehicle into the parking area. The person may subsequently leave the parking area on foot and regain entry to the parking area by presenting the same card. Later, the same card is used to exit the parking area, via the vehicle, and to validate that the same person is leaving with the vehicle. The parking area control and management system also includes sensors, such as loop detectors and electric eyes, to determine if a second vehicle or a pedestrian follows behind a vehicle entering into, or exiting from, the parking area. The parking area control and management system can be used to manage existing loop detectors and electric eyes, that normally control door and gate safety access systems, and to integrate those devices into an alarm system, such that an alert is issued whenever an abnormal or unauthorized event occurs during operations.
