A system and method which allows automatic recognition of any of three common monitored motorized door or gate safety edges or other entrapment protection devices. The invention allows retrofitting existing motorized door operators without enough monitored input ports to allow for more monitored entrapment devices required on laterally moving motorized gates. The system interfaces with obstruction monitoring devices in normally closed, pulsed, or resistive termination operating environments found in entrapment protection systems. Firmware logically analyzes the state of each edge or entrapment protection device to select and direct an appropriate output signal for a motorized gate operator. An operational example is disclosed which provides for up to six different device inputs and two separate outputs for the motorized door operator, which can be configured through dual inline package switches allowing field configuration.

Mechanism for the movement of a wing of furniture with a downward folding opening, designed to be placed on one side of the furniture item, the mechanism being contained in a box consisting of two half-shells, and including a hinge including a plurality of levers, articulated one in relation to the other, to the box and to the wing for the movement of the latter, one of the levers being able to slide in a track formed in the box, another of the levers being able to rotate around a fulcrum point provided on the box and acting with one of its ends on the front side of a linear slider, the rear side of which acts on one end of a rocker lever, whose other end acts on.

A hinge for doors of domestic appliances, comprising a first element and a second element pivoted to each other and movable relative to each other in tilting fashion, the first and second elements being fixable one to a frame and the other to a door of an electrical household appliance, for making the door movable with respect to the frame between a dosed position and an open position, a lever for connection between the first and the second closing elements, an elastic element connected to the lever and designed to generate with its own deformation a force of elastic adjustment designed to compensate at least partially the weight force of the door during the opening or closing of the door, means for adjusting the intensity of the elastic reaction force.

A drive arrangement for a motor vehicle flap including a gas pressure element, the gas pressure element has an outwardly sealed cylinder and a piston moveable in the cylinder interior along the cylinder axis and subdivides the cylinder interior into two sub-chambers, the gas pressure element has a first drive connection connected to the cylinder, and a second drive connection connected to the piston, the cylinder filled with a fluid and the piston has an overflow channel arrangement to create a balancing flow between the two sub-chambers to balance a pressure drop between the two sub-chambers. The piston is assigned a switchable valve arrangement which, depending on the pressure drop between the two sub-chambers, to create different through-flow states differing the cross section of the overflow channel arrangement. Upon exceeding a predetermined threshold for the pressure drop, the valve arrangement switches to change the cross section of the overflow channel arrangement.

A control system for a sliding door operator system, having at least one sliding wing and a door header, includes a first sensor configured to define a first activation zone, a first wing presence zone and a first side presence zone, a second sensor configured to define a second activation zone, a second wing presence zone and a second side presence zone, and a controller configured to evaluate data from the first sensor and the second sensor for controlling operation of the at least one sliding wing in the sliding door operator system.

Spindle assembly for a spindle drive device (10) comprising a thrust tube (30) and a spindle nut (32), which is arranged on the thrust tube (30) in a rotationally fixed manner, wherein the spindle nut (32) can be brought into threaded engagement with a spindle (26) of the spindle drive device (10), and wherein an end stop for the spindle nut (32) is arranged on the spindle (26), wherein the end stop comprises a damping element (36) consisting of a resiliently formed and hollow-cylindrically shaped stamped part (60).

At least one leaf of this door is equipped with a detection device comprising a mechanical detection device and a contactless sensor each capable of detecting a presence. The control circuit board comprises a control unit for movement of each leaf and a diagnostic unit, while means transfer, from the detection device in the direction of the diagnostic unit and the control unit, a first item of information representative of the activation state of the mechanical device, and a second item of information representative of the activation state of the contactless sensor. The diagnostic unit can identify a malfunction at least of the contactless detection device, when the first item of information has an active value while the second item of information has an inactive value. The invention allows redundancy to improve the availability of the detection device, while performing predictive maintenance for the operator, in particular a malfunction of the contactless sensor.

A commercial vehicle used for parcel delivery is installed with a control module. The control module communicates wirelessly with a transmitter to give control to the vehicle operator. The vehicle operator can access the vehicle's cargo compartment through the bulkhead door and/or the rear door solely by using the transmitter as opposed to manually actuating the door latch. A door actuator is added to the bulkhead door such that when the bulkhead door is wirelessly actuated the door opens without operator assistance, and the process of the door opening does not damage the vehicle. Additionally, the vehicle operator can initiate the control module to allow a push-button start and stop of the vehicle's ignition system. Such elements contribute to time savings and cost savings for parcel delivery operators.
