A method of operating an entry system of a motor vehicle includes monitoring a battery voltage and the entry system continuously using a control circuit of the latch assembly in a non-emergency mode. Power is provided to the control circuit in the event of a loss of power from a main power source using a backup energy source of the control circuit. The method includes transitioning to an emergency mode in response to determining loss of power from the main power source or failure of the component of the entry system. An actuation group associated with the latch assembly is operated with the control circuit using power from the backup energy source of the control circuit in response to determining that actuation from a plurality of pins of a mechanical emergency switch assembly indicates a command from a user to unlatch the closure member in the emergency mode.

The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11). The method comprises the steps of: detecting door movement; determining if detected door movement relates to unexpected door movement; and, if so, taking action so as to prevent more extensive damages. The disclosure further relates to an overhead door operator system for opening and closing an opening.

A method for determining the tension of a drive belt, wherein the drive belt is provided for transmission of a torque generated by a drive unit to a load, for example, a door leaf of a door system includes a first process step a., the load is moved from a moving state into a rest state. In a following process step b., the motor voltage is recorded during execution of process step a. and the time-resolved motor voltage curve is prepared. In step c., the motor current is determined from the recorded motor voltage or the motor voltage curve and a time-resolved motor current curve is prepared. In a last step d., the time-resolved motor current curve is evaluated and the tension of the drive belt is determined by means of selected curve features of the motor current curve.

A method for determining and/or verifying a status of a door system includes the following steps: determining at least one item of measurement information relating to the door system in a measuring step, and determining and/or verifying the status of the door system using an artificial intelligence system and using the at least one determined item of measurement information in a status determination step.

The disclosure relates to a corner bracket (14, 16) for a vertical moving door (2), the corner bracket (14, 16) comprising: a base plate (32) configured to be attached to the door (2); and a guide path (34) for a lift cable (4, 6) arranged in the base plate (32). A switch (28) is arranged in the base plate (32) and configured to be actuated by the lift cable (4, 6) in the event of a breakage of the lift cable (4, 6). The disclosure further relates to a method, performed by a control device (200), for stopping a vertical moving door (2) of a vertical moving door system (100), the vertical moving door system (100).

Methods and apparatus to monitor and/or adjust operations of doors are disclosed. An apparatus includes processor circuitry to execute instructions to: monitor a position of a door panel associated with a door system; detect when a beam from a photo-eye sensor associated with the door system is in an unexpected non-triggered state based on the position of the door panel; and generate an alert or notification indicating a significance of the beam in the unexpected non-triggered state.

Methods and apparatus to adjust door operations in response to surface pressure loads are disclosed. An apparatus includes sensor feedback analyzer circuitry to detect a surface pressure load acting on a door based on feedback from a sensor. The door includes a panel to move along a track. The apparatus also includes operations controller circuitry to control operations of the door. The operations controller circuitry is to automatically adjust an operation of the door in response to detection of the surface pressure load.

A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.

A device for identifying and monitoring the state of an arrangement to be monitored having an openable and closable wing element is provided. The device has a housing, which has a housing base securable on or connected in one piece to the arrangement and a second housing part attachable to and removable from the housing base. The device is also provided with an identification marker, the housing base has a first identification marker for the arrangement to be monitored having an openable and closable wing element, and the second housing part has at least one second identification marker identifying the second housing part.

A sliding door driving device includes: a power source; a motor that outputs power to open and close the door; a motor driving circuit that connects the power source and the motor to each other; and a motor control device that controls the motor driving circuit. The motor control device includes an inverter that converts DC power supplied from the power source into AC power, and a shunt resistor disposed between the power source and the inverter. The position detection unit of the motor control device obtains the rotation angle of the motor based on the output of the shunt resistor.
