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.

An automotive vehicle includes a closure arranged relative a closure frame to selectively cover an opening to the vehicle. The vehicle also includes an actuator configured to move the closure among a plurality of positions including open and closed positions, and a first sensor configured to detect motion of the closure among the plurality of positions. The vehicle additionally includes a latch assembly with an engaged state to retain the closure in the closed position and a disengaged state to permit the closure to move among the plurality of positions. A second sensor is configured to detect the engaged or disengaged state of the latch assembly. The vehicle further includes a controller which is configured to, in response to the first sensor detecting motion of the closure among the plurality of positions and the second sensor detecting the latch assembly in the engaged state, provide a diagnostic signal.

The present invention relates to a door operator system and a method performed in a door operator system for moving at least one door leaf between a closed and an open position, comprising a door operator and a supervise unit, wherein the door operator comprise a drive unit adapted to be connected to and to move the at least one door leaf between the open and closed position, at least a first presence sensor connected to a control unit and configured to monitor at least an risk area and to send presence data associated with that an object is detected in the risk area to the control unit, at least a first and a second activation sensor connected to the control unit, wherein the first activation sensor is configured to monitor at least a first activation area at an outer side of the door leaf, the second activation sensor is configured to monitor at least a second activation area at an inner side of the door leaf, and the first and second activation sensors are arranged to send activation data to the control unit associated with that an object is detected in the first and/or second activation area, the control unit is connected to the drive unit and arranged to control the movement of the drive unit at least based on the received activation data and presence data, and wherein the supervise unit is connected to and adapted to receive activation data from the at least first and second activation sensors and presence data from the at least first presence sensor and configured to identify a conflicting data in a sequence of activation data and presence data.

The invention relates generally to the field of motorized garage door openers. In particular, the invention relates to wireless safety sensors for garage door openers and garage door opener with a wireless safety sensor. The wireless safety sensor has a wireless communication link with a main control unit of the garage door opener. The wireless safety sensor also has an internal wireless link, i.e., a detection beam link, between a master unit and a slave unit. The wireless safety sensor periodically verifies that the wireless communication link has good signal quality and maintains the quality of the wireless communication link.

The present invention relates to a door operator and a method performed in a door operator (1) for moving at least one door leaf (5) between a closed and an open position, comprising a drive unit (2), a control unit (3) and an supervise unit (4), wherein the drive unit (2) is adapted to be connected to and to move the at least one door leaf (5) between the open and closed position, the control unit (3) is connected to the drive unit (2) and arranged to control the movement of the drive unit (2), the supervise unit (4) comprise one or more sensors (6-1, 6-2, . . . , 6-m) configured to provide sensor data associated with the operation of the door operator (1) and/or the at least one door leaf (5); a status management unit (12) configured to: receive the sensor data from the one or more sensors (6-1, 6-2, . . . , 6-m); determine a status pattern of the operation of the door operator (1) and/or the door leaf (5) out of a plurality of status patterns of the operation of the door operator (1) and/or the door leaf (5) at least based on the received sensor data, wherein at least a first status pattern out of the plurality of status patterns is associated with a status event, and trigger the status event in response to determination of at least the first status pattern.

The disclosure proposes a method performed in an electronic device for minimizing downtime in operation of a door system. The method comprising obtaining a door system identification information, followed by obtaining a status pattern associated with the operation of the door system associating the obtained status pattern with the door system identification information. The method is determining if the obtained status pattern is associated with any of at least one reference status pattern, by comparing the obtained status pattern with the at least one reference status pattern. This is then followed by associating the determined reference status pattern with the door system identification information and generating a door maintenance information.

A method for operating a door system, wherein the door system has at least one door leaf, and wherein a sensor unit is configured and connected to a control unit of the door system, wherein the approach of a person to the door system is detected using the sensor unit, in particular designed as a radar sensor or as a camera, wherein the method has at least the following steps. Detecting an approach angle of the person, at which the person approaches the door system and opening the at least one door leaf at an opening width and/or at an opening speed, wherein the maximum opening width or the maximum opening speed is determined by the control unit as a function of the detected approach angle of the person. The method also relates to a door system with a control unit for carrying out the method.

The present invention relates to a refrigerator which allows a user to open the doors of the refrigerator easily. The present invention relates to a refrigerator and a method for controlling same, the refrigerator being capable of preventing the doors of the refrigerator from automatically opening due to a malfunction.

Embodiments of a system and method for controlling a door are generally described herein. A door opener system can include a head unit. The system can include a wall station, a controller, or a wireless transmitter. The wall station can be inside a room, the room including the door and the controller can be outside the room. The wireless transmitter can be portable. The wall station, controller, or wireless transmitter can be used to control the head unit. The head unit can be used to open or close the door.

A diagnosing device identifies a plugging operation period in which a plug door performs a plugging operation, the plug door having a guide roller attached thereto, the plug door being configured to perform an opening-closing operation and the plugging operation by allowing the guide roller to move along a guide rail; obtains drive information including a value representing at least one of a current value or a torque value of a drive unit, the drive unit being configured to drive the plug door; and diagnoses an abnormality in the guide roller or the guide rail based on the drive information observed during the identified plugging operation period.
