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.

The present disclosure relates to a safety power window system capable of detecting jamming of an object between a window and a door frame by generating virtual pulse signals on the basis of pulse signals generated by two hall sensors positioned to have an interval of 90 degrees therebetween to calculate force acting on the window even though a window motor rotates only 0.75 turns, and an operation method thereof.

A door operation management system (100), method and computer program product for controlling operation of a door (1), the door operation management system (100) comprises at least a first movement sensor device (10a, 10b, 10c) arranged at the door (1), for determining a movement of the door (1); and a processing circuitry (102a, 102b) operatively connected to the at least first movement sensor device (10a, 10b, 10c) configured to cause the door operation management system (100) to obtain at least a first sensor data (dd1, dd2, dd3, dd4) from the at least first movement sensor device (10a, 10b, 10c); and determine at least a first state (st1, st2, st3, st4) of the door (1) based on the at least a first sensor data (dd1, dd2, dd3, dd4).

A vehicle (e.g., a class-2 vehicle) with an improved cab door is disclosed. The vehicle can have a vertical plane that bisects the vehicle into a driver's side and an opposed side. The vehicle can comprise a chassis and a body supported by the chassis. The body can define a cab. The cab can define an opening configured to provide operator access to the cab. The cab door can be configured to travel about and between an open position and a closed position along a linear axis. In the closed position, the cab door can at least partially cover the opening of the cab. The linear axis can form an acute angle with the vertical plane that bisects the vehicle.

An automatic door can include a plurality of millimeter wave (mmW) sensors that are each configured to sense a door area. Each mmW sensor includes a mmW radar configured to capture mmW radar data and an inertial measurement unit (IMU) configured to measure an orientation of the mmW radar. Based on IMU data from the mmW sensors, the mmW radar data from the sensors can be combined so that the door areas can form a combined door area. Multiple targets can be detected and tracked through the combined door area at high resolutions and in a variety of environmental conditions. Control of the automatic door can be enhanced in a variety of ways by classifying the targets and predicting their movements in the combined door area. Further, the classification and prediction of targets can facilitate safe and reliable operation by filtering operation based on certain targets and/or motions.

A power assist device is provided herein. A motor is operatively coupled to a door of a vehicle. A controller controls the motor and a user-input device supplies to the controller one or more user-inputted selections for controlling door swing.

A furniture drive system includes: a support for mounting the system on a furniture carcass; an actuating arm device movably mounted on the support and to be connected to the movable furniture part; an electric motor to be connected to the actuating arm device to move sections of the actuating arm device; a drive device separate from the electric motor for exerting a force on the actuating arm device; an adjusting device for adjusting the force to be exerted by the drive device; and a control device for controlling the electric motor. The control device has a determining device for determining the force to be exerted on the actuating arm device, and the drive device has a damping device to dampen a closing movement and/or an opening movement of the actuating arm device. The determining device is designed to perform a damper analysis of the damping device.

Hinge for the movement in opening and closing of a door with respect to a shoulder of a furniture item, said hinge including return closing mechanisms, a first fixed part attached to the shoulder, and a second movable part attached to the door, the fixed part and the movable part being articulated one to the other so as to be able to rotate around a pin, which constitutes the axis of rotation of the hinge, wherein the return closing mechanisms include at least one spring arranged around the pin exerting a force in the direction of the axis of the pin in the final phase of closing, tending to rotate coupling surfaces of the fixed part and movable part of the hinge.
