An optoelectronic safety device for monitoring a machine movement includes a detection device and a control device. The detection device includes a transmitter unit which transmits an optical signal having a sequence of signal pulses, each of which has a different pulse intensity, and a receiver unit which receives the optical signal. The control device includes an evaluation unit which evaluates the optical signal received by the receiver unit, a pulse selection index, and a pulse selection unit which changes the pulse selection index if the pulse intensity of one of the signal pulses is outside of an optimal intensity range. The control device enables the machine movement if an intensity of a received signal is within a permissible intensity range, and outputs a trigger pulse to stop the machine movement if the intensity of the received signal is outside of the permissible intensity range.

An infrared (IR) sensor for use in a door sensor. The IR sensor may include one or more rows of emitters configured to generate an emission beam. The emission beam may have a width that is at least a width of an opening below the door sensor. The IR sensor may also include one or more rows of receptors configured to receive an evaluation beam. The receptor beam may have a maximum width that is at least the width of the opening. At least a portion of the receptors may be further configured to be one or more of deactivated and ignored, such that the width of the evaluation beam is reduced to correspond with a reduced width of the opening during a closing of a door.

An infrared (IR) sensor for use in a door sensor. The IR sensor may include a plurality of emitters arranged in multiple rows. Each emitter of the plurality of emitters may be configured to emit an emission beam comprising IR light. A plurality of receptors may be arranged in multiple rows. Each receptor of the plurality of receptors may be configured to receive a reception beam comprising the IR light reflected off of a surface. One or more lenses comprising refractive elements may be configured to duplicate and direct one or more of the emission beams and one or more of the reception beams onto the surface to form an IR pattern. The IR pattern may include multiple IR curtains. One or more of the receptors and/or emitters may be deactivated to change a width of the IR pattern and/or number of IR curtains.

A dual sensor module for a garage door opener is provided. Embodiments of the dual sensor module include a plurality of input terminals for at least two sensors configured to detect an object in a path of a garage door. There is an output terminal for providing a signal to a motor control unit for the garage door opener wherein the signal prevents the garage door from closing when the object is in the path of the garage door.

Systems, methods, and apparatus for managing and controlling network-enabled movable barrier operators is provided. A method for managing network-enabled movable barrier operator includes receiving a user account identifier and a movable barrier operator identifier from a user device, providing an instruction to perform a specified action with a movable barrier operator associated with the movable barrier operator identifier to the user device, determining a registration condition is met upon detecting that the specified action has been performed, and, in the event that the registration condition is met, associating the movable barrier operator identifier with the user account identifier to allow a user account associated with the user account identifier to control the movable barrier operator over a network.

Light grid for protecting the door edge of a motor-driven door against collision with an object, having a transmitter strip and a receiver strip with transmitter elements and receiver elements, for detecting an object in the plane of the door panels by interruption of the reception of individual receiver elements. An evaluation device distinguishes between normal and safety cases based on the detection of a status for the door, identifies the safety case if the number of uninterrupted receiving elements between door edge and object falls below a critical number, and identifies the normal case if the safety case is not identified. A communication device outputs a signal for the status. The evaluation device determines a distance value corresponding to the number of uninterrupted receiver elements below the door edge up to the first interrupted element, and the communication device varies the frequency as a function of the distance value.

Garage door opening systems commonly include lighting generated from lower wattage bulbs mounted to an electric operator near a garage ceiling. This lighting is inadequate to fully illuminate a garage space particularly at the floor level. Since vehicles park under the light, the vehicle can become a blocker of light. Disclosed are garage door opening systems including a safety eye light which integrates a light source into the safety eye of a garage door opening system thereby providing additional illumination to poorly lit areas of a garage. This additional source of lighting helps assure users safer home to vehicle ingress and egress. In some forms, the lights in the safety eye light are fixed, in other forms the lights are adjustable in direction. Various methods of integrating a safety eye light into a garage door opening system and use of the safety eye light are disclosed herein.

A non-contact obstacle detection (NCOD) system for an opening in a vehicle includes a cover panel, such as a glass pane, slidable between opened and closed positions within the opening. The system includes one or more infrared time-of-flight (IR-TOF) sensors which measure the length of a beam of infrared light by measuring the time that the infrared light in the beam takes to travel the length of the beam and to reflect back to the sensor. The IR-TOF sensors may be configured to provide a beam of light along either the side edge of the frame parallel to the sliding direction or a terminal edge generally transverse to the sliding direction. Methods are provided for detecting obstacles within the opening of the frame by controllers using the lengths of beams from each of those different beam configurations, and for self-calibrating the system.
