The sensing edge includes an elongate sheath, a first end plug and a first end flap. The elongate sheath has a first end and a second end. A first cavity is located at the first end. The elongate sheath is mounted to the forward edge. The first end plug includes an inner end, an outer end, first engaging structures extending from the inner end and a first vertical groove in the outer end. The engaging structures are positioned within the first cavity in an assembled configuration. The first end flap includes a relatively flat first body and a first flange structure. The first flange structure is positioned in the first vertical groove in the assembled configuration to secure the first end flap to the first end plug.

A vehicle barrier gate system which is positioned above a roadway through which vehicles pass. Some of the various embodiments of the present disclosure include a gate comprised of an arm and barrier which is adjustable between a raised position in which a vehicle may pass and a lowered position in which a vehicle is prevented from passing. The gate may be movably connected to a ceiling or an overhead support structure positioned above the roadway. Various types of actuators may be utilized to adjust the gate along a linear and/or angular path between the raised and lowered positions. A control unit may be in communication with one or more sensors and/or an authorization system to control the actuator. The gate may include a breakaway mechanism which allows the gate to be manually raised or lowered in the event of actuator failure or a vehicle ramming through the gate.

A hinge (100) including a first hinge leaf assembly, a second hinge leaf assembly pivotally coupled to the first hinge leaf assembly (101), a spring (138) operatively connected to the first and second hinge leaf assemblies, and a spring tensioning mechanism to adjust the bias of the spring (138). The first hinge leaf assembly includes a first hinge component (101) having a first mounting surface for securing to a first structure and a plurality of first knuckles (114, 115). The second hinge leaf assembly includes a second hinge component having a second mounting surface for securing to a second structure and a second knuckle (123). The spring biases the first hinge leaf assembly and the second hinge leaf assembly toward a closed position, wherein the spring is located with a hollow defined by coaxial alignment of the plurality of first knuckles (114, 115) and the second knuckle (123).

A spindle drive for an adjustment element of a motor vehicle, including a tubular drive housing having a first housing pipe, a spindle/spindle nut transmission configured to produce linear drive movements, a first drive connection and a second drive connection configured to discharge the drive movements, the first drive connection forms with one of the transmission components a first drive train component and the second drive connection forms with the other of the transmission components a second drive train component. A housing cover axially closing the drive housing and arranged in an axially secure manner relative to the first drive connection. The first housing pipe arranged in an axially secure manner relative to the first drive connection. A housing collar in a first coupling portion of the spindle drive connected to the first housing pipe and in a second coupling portion coupled to the housing cover.

A spindle drive for a closure element of a motor vehicle including a downstream spindle/spindle nut mechanism, a spindle, a spindle nut and a spindle guide tube, for producing drive movements along a drive axis. A number of drive connections adjustable with respect to one another to transmit the drive movements, the first drive connection axially fixed to the spindle guide tube, a second drive connection axially fixed to the spindle, a drive spring configured to produce drive movements along the drive axis, the spindle guide tube has a first outer radius extending along at least one axial portion and on a side facing the first drive connection, a tube end portion with a tube end edge, that the tube end portion is widened radially so that the tube end edge has an outer end edge radius which is greater than the first outer radius.

A locking mechanism (10) for a hinge (4) is disclosed. A latch member (11) engages with a lip (12). A positive drive means (20, 23, 24, 41) enables the latch member to be driven into and out of engagement with the lip. The driven engagement when the hinge is used in relation to columns (1, 101) prevents small movements at the hinge being magnified into large movements at the end of the column members. The driven dis-engagement enables the hinge to be opened notwithstanding mechanical loads, corrosion, insect nests and similar obstacles. The drive means preferably takes two forms, namely threaded fasteners (20, 23, 24) and a spring loaded rotatable actuator (41) with ramped surfaces (48, 49) which male with ramped surfaces (61, 62) on the latch member (11).

A protector with a sensor is installed on a sliding door for detecting an object by touch between two core wires in a hollow part. In a terminal part of the protector with the sensor, the core wires drawn out are connected with legs of a resistor. A primary seal is formed by grinding a surface of the hollow part of the terminal part of an extrusion molded part, positioning a ground part on a die and covering wire connection parts and a side of another end of an insert while also covering the ground part by means of injection molding. A secondary seal is formed by means of the injection molding for coating a part formed with the primary seal for forming an external shape of a product.

A protector with a sensor is installed on a sliding door for detecting an object by touch between two core wires in a hollow part. In a terminal part of the protector with the sensor, the core wires drawn out are connected with leads joined with a control unit. A primary seal is formed by means of injection molding for covering wire connection parts and another end side of an insert while also covering a skin of a wire harness which ties and coats the two leads. A secondary seal is formed by means of the injection molding for coating a part formed with the primary seal and for forming an external shape of a product.

Methods and systems are described for determining operation of an openable barrier into a building. A method for determining an open state of a barrier may include identifying a first position for the barrier, the barrier having at least one hinge and a hinge sensor magnetically mounted to the at least one hinge. The method may further include determining, based at least in part on the hinge sensor, when the barrier changes position from the first position to a second position. The method may further include wirelessly transmitting data concerning the change in position of the barrier.
