A multi-turn limiting device for limiting movement of an element driven by a motor includes a sensor configured to provide a sensor signal corresponding to a position of the element, a movable member mechanically couplable to the element via a transmission having a non-unitary first transmission ratio and a further sensor configured to provide a further sensor signal corresponding to the position of the movable member. A controller switches the motor via a switching signal determined on the basis of the two sensors. A method of limiting movement of an element driven by a motor includes sensing the position of the element using two sensors and a movable member which is coupled to the element via a non-unitary transmission ratio.

Various embodiments of systems and methods for remote monitoring and controlling of electrochromic glass are described. In some embodiments, a device monitoring and control system can receive messages via a communication hub from a plurality of remote installation sites for electrochromic glass units. The messages include telemetry data associated with the electrochromic glass units. The system can stream the telemetry data to a data analytics engine that can perform analytics functions on the telemetry data. The system provides results of the analytics functions to remote destinations via a data analytics interface. The system can also receive, via a control interface, control instructions from remote sources to control one or more of the electrochromic glass units. The system can transmit control messages to the installation sites to implement the control instructions. The system can also establish a connection for a requestor to an installation site using a site's specific connection protocol.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for interaction with a connected outdoor gate lock. The methods, systems, and apparatus include actions of detecting, by a control unit, that a gate of a fence that encloses a building has opened, in response to detecting that the gate of the fence that encloses the building has opened, determining, by the control unit, whether (i) a pet is in the building and (ii) a pet door of the building is unlocked, and in response to determining (i) that the pet is in the building and (ii) that the pet door of the building is unlocked, locking, by the control unit, the pet door of the building.

The present invention relates to a system for monitoring an elevator door, an elevator system, and a method for monitoring an elevator door. The elevator door has an open state or a closed state implemented by moving along an elevator sill. The system for monitoring an elevator door includes: one or more imaging sensors configured to collect image data and depth data of at least one section in the elevator sill that is exposed when the elevator door is in the open state; and a data processing device in communication with the imaging sensor and configured to receive and process the image data and the depth data to determine whether an obstacle preventing the elevator door from entering the closed state exists in the section. By applying the present invention, the safety of the elevator door can be improved effectively, and equipment property losses and personal injuries can be avoided.

A machine tool includes a bed, a column, a rotary main spindle, a tool magazine, a tool changer, and a controller. The tool changer includes a body provided on the bed so as to be movable in a direction orthogonal to a movement direction of the column, a changing arm rotatably provided on the body, and a door provided on the body to open or close an opening formed in the body, and configured to partition an area on the column side from an area on the tool magazine side by closing the opening. The controller is configured to move the body in parallel with at least one of an operation of opening the door and an operation of closing the door.

Method for configuring an actuator (2) for the operation of a moving element (3) for closure, solar protection, privacy or screening, said actuator comprising a gear motor (4) and a gear motor electronic control unit (5), said electronic control unit incorporating a memory (51) in which at least one range of travel of the element has been pre-recorded, and said method comprising a step for the relative modification of the magnitude of at least one range.

A machine tool system and an opening stop position calculating device are provided. The machine tool system includes an openable and closable door for closing an opening of a cover surrounding a machine tool. Furthermore, the machine tool system includes an opening width setting unit for setting an opening width of the door, an opening stop position calculating unit for calculating an opening stop position of the door at which a total time, which is obtained by summing a time required to move the door from a fully closed position to a position of the set opening width and a time required to move the door from an opening stop position where the door is opened and stopped to the fully closed position, is minimized, and a door control unit for controlling opening and closing of the door based on the calculated opening stop position when exchanging the workpiece.

The invention relates to a self-learning repetitive method for an electrical drive or motor, in particular a linear or slewing drive, for determining the maximum speed during the movement of the actuator between a starting point (SP) and an end point (EP), wherein the actuator is accelerated to a speed v.sub.max over a first distance (x.sub.beschl), is braked over a second distance (x.sub.brems) and is then moved at a safe low speed (v.sub.safe) over a third distance (x.sub.safe) as far as the stop and is stopped. The method is repeated with the aim of minimizing the third distance (x.sub.Safe,min) and thereby achieving the maximum speed (BPmax, v.sub.max). The method also provides for taking into account the external interfering influences, for example external forces and friction. The invention also relates to such an electrical drive.
