The present invention relates to a garage door emergency ventilation system primarily comprised of at least one track, at least one screen assembly, and at least one control module. The system can be attached to a panel of a garage door, wherein the control module has at least one sensor that preferably detects carbon monoxide. Once the sensor has detected carbon monoxide above a threshold value, the control module communicates with a motor to retract a fastener from an inner track within the track that is attached to the screen assembly. At the same time, the control module communicates with a garage door opener of the garage door to open the garage door. The screen assembly falls downward to cover the opening left by the opened garage door. The screen assembly further prevents individuals from getting into the garage while allowing carbon monoxide gas to vent from the garage.

A method is provided for operating a movable barrier operator system in connection with a delivery. The method includes, at the movable barrier operator system, receiving a delivery open command and moving a movable barrier from a closed position to an open position. The method further includes identifying a delivery timer value based at least in part upon the delivery open command, operating a timer using the delivery timer value, and moving the movable barrier from the open position toward the closed position upon expiration of the timer.

A wireless transmitter for controlling a barrier operator includes at least one processor, an actuator, and a memory storing instructions. When executed by the at least one processor, the instructions cause the at least one processor to transmit a first data packet configured to initiate actuation of the barrier operator on a first channel and transmit the first data packet on a second channel. The transmission on the first channel may be performed in response to a first actuation of the actuator and the transmission on the second channel may be performed in response to a second actuation of the actuator. Alternatively, both transmissions may be performed in response to a single actuation of the actuator but switching from the first channel to the second channel may be performed in response to a passive input signal.

A sealing assembly for pressing a garage door horizontally into weather stripping or a door jamb; the sealing assembly having at least one cam-stop assembly, the cam-stop assembly further having at least one cam assembly, at least one linking assembly coupling the cam-stop assembly to the cam assembly, and at least one stop brace. The garage door is sealed when a combination of cam-stop assemblies having cam assemblies—further comprising at least two triangular hinge plates and corners—couple with stop braces and rotate counter-clockwise by exertion of torque to move the garage door forward and downward to form a snug seal with the side of the door jamb and also the bottom floor.

In one aspect, an in-vehicle device is provided that includes a sensor configured to detect a vehicle characteristic indicative of the vehicle being in proximity to a location associated with a movable barrier operator. The in-vehicle device includes communication circuitry to communicate an open command to the movable barrier operator that causes the movable barrier operator to open a movable barrier connected to the movable barrier operator. A memory is configured to store a vehicle arrival condition indicative of whether the vehicle arrived at the location associated with the movable barrier operator. A processor is configured to determine satisfaction of the vehicle arrival condition and, upon the vehicle arrival condition not being satisfied, cause the communication circuitry to communicate a close command to the movable barrier operator that causes the movable barrier operator to close the movable barrier.

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.

The present invention relates to a method for determining the door position in a door system which has a rail for guiding a movable door element and a sensor element (10) for detecting a free movement path of the door element (50), the method comprising the steps of: detecting the state of the at least one sensor element (10), which can either be free of the door element (50) or covered by the door element (50), such that, in the event of a change in the state of the sensor element (10), the arrangement position of the sensor element (10) corresponds to the door element (50), and a door control lines the door position with the aid of this information.

In one aspect, a garage door opener system includes a battery configured to be charged by a power source, a controller coupled to the battery, the controller configured to operate a motor that is powered only by the battery, at least one sensor coupled to the motor and the controller, the at least one sensor generating sensor data, and a battery monitoring system coupled to the battery, the controller, and the least one sensor, the battery monitoring system configured to monitor a power consumption of the battery and a state of the battery, and to update an operation configuration of the controller based on historical power consumption of the battery, the state of the battery, and the sensor data.

Access control for an autonomous vehicle through a door in a doorway. A magnet is attached to the autonomous vehicle and a magnetometer is located some distance from the doorway. The magnetometer outputs a magnetometer signal in response to detecting the magnet, which causes the transmitter to transmit a detection signal. A doorway device is fixed about the doorway, and includes a receiver, and a locking mechanism with a locking pin. The doorway device retracts the pin to unlock the door for a predetermined period of time in response to receipt of the detection signal, and extents the pin to lock the door after the predetermined period of time ends.

Garage door openers and methods of operating garage doors to reduce the risk of carbon monoxide poisoning. Such a garage door opener includes a motor unit configured to raise and lower an overhead garage door of a garage functionally coupled thereto, and an carbon monoxide (CO) detector that detects and measures a concentration of carbon monoxide gas in the garage. The CO detector directly delivers a signal to the motor unit in response to the detected concentration of carbon monoxide gas exceeding a predetermined CO threshold level for at predetermined duration, so that the garage door opener raises the overhead garage door with the motor unit.
