During operation of the door system one or more sensors may be utilized in order to monitor the operation of the door assembly (e.g., door system, door, frame, etc.), review the operating parameters, troubleshoot potential issues, schedule and monitor service requests, review and take actions for potential security threats, and/or the like. Consequently, users may determine if the door system operates the door in accordance with the desired operating parameters by reviewing the movement, vibration, speed, acceleration, force, or the like based on the sensor information captured and use the information to adjust the door assembly. Notifications regarding the operation of the door systems may be sent automatically and/or in response to requests from users. The users may utilize one or more applications and interfaces thereof to remotely connect to the door systems in order to review and analyze the sensor information and take the desired actions.

A method for operating a tailgate of a motor vehicle, in particular a pickup, which is driven by means of an electric motor and delimits a cargo area. A disassembled state is detected, and energization of the electric motor is inhibited. Furthermore, the invention relates to a motor vehicle.

A fire damper actuation system in an HVAC system includes a damper system and an actuator system. The damper system includes damper blades rotatable between an open configuration and a closed configuration, a crank arm assembly configured to drive the damper blades, a spring assembly configured to be held in a loaded condition when the damper blades are in the open configuration, a temperature-activated fusible link, and a fusible link arm coupling the temperature-activated fusible link to the crank arm assembly. The actuator system includes a motor and a drive device. The drive device is coupled to the crank arm assembly and the temperature-activated fusible link. Operation of the drive device by the motor between a first end stop location and a second end stop location simultaneously rotates the crank arm assembly and the temperature-activated fusible link to complete a test inspection procedure.

A door closer system having a door closer that includes at least one sensor configured to sense an operating characteristic or condition relating to the door closer including a position or speed of displacement of at least a portion of the door closer or an associated entryway device. The sensor(s) can also provide information relating to the performance or condition of one or more components of the door closer, such as the operation of a backcheck mechanism, as well as tracking the number of door cycles. Information obtained by the sensor(s) of the door closer system can be communicated to a lockset device of an entryway control system. The lockset device can be configured to communicate information received from the door closer system to an access control system, which can in turn provide the communicated information to a management system.

A door operator system and a method for moving a door leaf between a closed and open position utilize a door operator and a supervise unit. The door operator includes a control unit, a presence sensor, activation sensors, and a drive unit. The drive unit is connected to the door leaf and moves the door leaf between the open and closed position to achieve a plurality of operational states. The presence sensor is configured to monitor a risk area and send presence data associated with an object detected in the risk area to the control unit. The activation sensors are configured to monitor respective activation areas near the door leaf and send activation data associated with an object detected in the respective activation areas to the control unit. The control unit controls a movement of the drive unit based on the activation and presence data.

A hinge is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations. The hinge, provided with a first wing member linked to a first linked object and a second wing member linked to a second linked object, and rotatably linking the second linked object to the first linked object, is provided with a sensor which detects prescribed change in the external environment in the hinge or around the hinge, and a control unit which externally transmits, over a communication network, information on the change in the external environment detected by the sensor, wherein the sensor is configured from at least one of: a rotation speed sensor for detecting the rotation speed of the second wing member relative to the first wing member; a vibration sensor for detecting the amount of vibration; a load sensor for detecting load; an angle sensor for detecting the opening angle of the second wing member relative to the first wing member; a temperature sensor for detecting temperature; and an air pressure sensor for detecting atmospheric pressure.

Systems, methods, and apparatus for detecting movable barrier disengagement are provided. A movable barrier operator system includes a motor configured to be coupled to a movable barrier and move the movable barrier, a motor sensor configured to measure a load value of the motor, communication circuitry configured to receive, from a remote control, a state change request to cause movement of the movable barrier, and a processor circuit. The processor circuit is configured to cause actuation of the motor in response to receipt of the state change request, detect, based on the load value, a disengagement between the motor and the movable barrier, and cause a communication to be sent, in response to detecting the disengagement, to a remote server, the communication indicative of motor disengagement.

The invention relates to a control device for controlling an externally-powered window lifter with anti-trap protection for a motor vehicle window. A control device of this type is designed to determine that an operating element for closing the window is actuated and, in response thereto, the window is moved in the closing direction. The control device is further designed to determine that the functional activity of the anti-trap protection is no longer guaranteed. In the case of a control device and in the event that it has been determined that the functional activity of the anti-trap protection is not guaranteed, the window lifter is actuated in response to the actuation of the operating element in such a way that the window is moved at a lower displacement speed in the closing direction when compared with the displacement speed with guaranteed functionality. In the case of an alternative control device and in the event that it has been determined that the functional activity of the anti-trap protection is not guaranteed, the window lifter is actuated in response to the actuation of the operating element with a predetermined actuation sequence of the window lifters in such a way that the window is displaced in the closing direction starting from the idle state.

A door closer system having a door closer that includes at least one sensor configured to sense an operating characteristic or condition relating to the door closer including a position or speed of displacement of at least a portion of the door closer or an associated entryway device. The sensor(s) can also provide information relating to the performance or condition of one or more components of the door closer, such as the operation of a backcheck mechanism, as well as tracking the number of door cycles. Information obtained by the sensor(s) of the door closer system can be communicated to a lockset device of an entryway control system. The lockset device can be configured to communicate information received from the door closer system to an access control system, which can in turn provide the communicated information to a management system.

A control device and method for a vehicle having an automatically opening and/or automatically closing flap includes an operating switch which can be operated contactlessly in the form of a proximity sensor and a programmable functional module. The method includes the following steps: firstly, an operating requirement signal is generated upon recognition of a predetermined proximity pattern consisting of the raw sensor signal of the proximity sensor for output of a resulting control signal to an unlocking and locking mechanism for the actual automatic opening or closing the valve, secondly, it is determined whether a predetermined absolute limit value of the raw sensor signal is exceeded, and thirdly, when the predetermined limiting value is exceeded, the output of the control signal is also suppressed when the operating requirement signal is generated, wherein this provision is also designated in short below as suppression mode.
