An obstruction detection system for motorized window shades is presented having a motor, shade material, a bottom bar, and a motor controller having a microprocessor. The microprocessor is configured to detect when an obstruction has been encountered when closing the motorized window shades. When an obstruction is detected, the microprocessor stops lowering the shade material and the bottom bar thereby preventing further damage or destruction. The system may also be used to report when an unexpected obstruction has been detected.

Example methods and systems to indicate the status of door operations are disclosed. An example door system includes a door panel having a leading edge to be moved in a travel direction between an open position and a closed position relative to the doorframe. The door panel to block the passageway when the leading edge is at the closed position. The door panel to unblock the passageway when the leading edge is at the open position. The example door system also includes a series of lights distributed along the travel direction proximate the doorframe. The example door system further includes a controller to switch the lights between a first state and a second state to provide a visual effect of movement corresponding to the operating status of the door system.

A safety curtain and system includes multiple light emitters and multiple light receivers to detect traffic approaching a doorway. The safety curtain my include pairs of multiple light emitters and receivers positioned on both sides of a passageway (doorway) so as to detect approaching traffic. The multiple light emitters and light receivers may detect a height of an approaching traffic (e.g., person or vehicle) and initiate warning lights of a possible door closing. The detected approach of traffic may cause the door to be stopped, reversed or slow down. The system may include a computer to monitor the signals from the receivers and may control the motion of the door.

A door arrangement (1), includes a safety device. A door arrangement monitoring method monitors a monitored area positioned in front of a door opening, offset and parallel to a door closing plane, and performs a failure routine when an object (6) is detected in the monitored area and there is a risk of a collision of the object (6) with a door leaf (2). A current position of the object (6), and of a leading edge (23) of the door leaf (2), are detected. A direction of movement of the door leaf (2) is detected. The failure routine is initiated as a function of the current position of the object (6) and the leading edge (23) of the door leaf (2) as well as the direction of movement of the door leaf (2).

A control system for driving a motorized closure element of a motor vehicle is provided, wherein, in order to detect operator control events, at least one sensor control means and at least one elongate distance sensor which extends along a sensor extent are provided, wherein the sensor control means drives the associated distance sensor, evaluates the sensor signals from the distance sensor or drives the associated distance sensor and evaluates the sensor signals from the distance sensor, and wherein the distance sensor detects a distance from a user. The control system can be configured such that when it is installed in a vehicle, a vehicle component can be arranged in or along the sensor extent, and that the distance sensor is designed such that it has a blind section in the region of the vehicle component, the blind section having no sensitivity or a lower level of sensitivity compared to that region of the distance sensor which adjoins the blind section.

A door, in particular a high-speed industrial door, with an intelligent door leaf is disclosed. The door has a door leaf which is guided by lateral guides and covers a door opening, and which has a first and a second side, a driving means for moving the door leaf between an open and a closed position, a door control means for controlling the driving means, as well as an electrically self-sufficient door leaf means arranged in the door leaf. The door control means also has a first communication unit. In addition, the door leaf device comprises at least one sensor unit for detecting at least a physical quantity, an energy converter which converts non-electrical energy into electrical energy, a second communication unit and at least one actuator unit. The first and second communication units communicate wirelessly with each other.

Monitoring systems for automatic doors comprise at least one input device configured for sensing at least one characteristic of at least one operational parameter of an automatic door system, a door system controller coupled to the at least one input device, at least one monitor display comprising a first interface operatively coupled to the door system controller, and at least another interface operatively coupled to the at least one monitor display and configured to be operatively coupled to at least one remote display device. The at least one monitor display is configured to continuously request information representative of the at least one operational parameter characteristic from the door system controller and display the information. Methods of monitoring an automatic door system comprise transmitting data representative of an operational parameter characteristic from an input device to at least one door system controller; sending a description of the operational parameter to a monitor display continuously; and displaying indicia representative of the description of the operational parameter.

The present invention concerns a motorized door comprising an array of n detection cells distributed along the length of the leading edge, capable of detecting the presence and distance, x, from said detection cell of a body positioned between said detection cell and a distal transverse edge. The detection cells are coupled to a CPU which triggers different actions during the closing of the shutter, depending on the proportion, P=n1/n of the number, n1, of detection cells identifying the presence of a body at a same time located at a distance, xxs, wherein xs is a predefined safety distance. (a) if PPs, wherein Ps is a predefined safety proportion, the detected body is considered as an accidental obstacle and the CPU is programmed to instantly stop the movement of the shutter; (b) if P>Ps, the CPU considers that the detected body is a distal transverse edge defining the end of the closure run, and orders to decrease the closing speed of the shutter until the leading edge contacts the distal transverse edge.

An example apparatus includes a sensor to detect a lateral edge of a door curtain within a guide of a door, and a controller to identify when the door curtain transitions from an operational state to a breakaway state based on a signal from the sensor, the operational state corresponding to when the lateral edge of the door curtain is enclosed by the guide as the door curtain moves between open and closed positions, and the breakaway state corresponding to when a portion of the lateral edge of the door curtain below an upper end of the guide breaks away from the guide.
