A door safety system (3) for a door (2), having a safety component (10) arranged on a movable door element (4, 4a, 4b) of the door (2) and a supply component (11) arranged on a stationary door frame (5) of the door (2) for supplying energy to the safety component (10). The safety component (10) has an electric energy store (12) which is designed to autonomously supply electric energy to the safety component (10) when the door (2) is open, and the safety component (10) and the supply component (11) are designed to electrically charge the electric energy store (12) of the safety component (10) when the door (2) is closed.

The present invention relates to exterior or interior doors for residential or commercial buildings, such as for a home, apartment, condominium, hotel room or business, and, more particularly, to a door provided with a rechargeable battery as a source of electrical power that may be used to operate electric devices mounted to the door. The door has electric devices attached thereto. The electric devices which. are powered by one or more rechargeable batteries that are charged by one or more energy harvester systems and/or by direct connection to a power source. A system for distributing the power collected from the energy harvester system and/or the wired connection are also provided.

Systems and methods are provided for protecting a door system from damage by a back electromotive force (EMF) voltage generated when a door coupled to a door actuator is manually closed. The door system may include a driver configured to drive the door actuator to move the door, and a back EMF protection circuit. The back EMF protection circuit detects a back EMF voltage generated by the door actuator when the door is moved, and determines whether the back EMF voltage exceeds an overvoltage threshold. In response to determining that the back EMF voltage exceeds the overvoltage threshold, the back EMF protection circuit causes the driver to transition to an enabled state to short the back EMF voltage to ground.

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.

The present invention relates to a motor vehicle that is equipped with an electrical door closing mechanism, a radio-based signal receiver and a control unit, wherein the door closing mechanism can be actuated after receiving and verifying an access authorization code by electrical signals that are generated by a control unit. The motor vehicle possesses an electrical charging apparatus accessible from the outside so that a signal generator that is provided to generate the access code can be charged from the electrical system of the motor vehicle in the event of an insufficient charge. Furthermore, the invention describes a method for charging a signal generator that can be executed using the device according to the invention.

A movable barrier opener system having a brushless DC motor is provided. The movable barrier opener system may have a power supply unit with a drive circuit power module and a storage bank. The storage bank may be chargeable by the drive circuit power module and may be connectable to the drive assembly to provide electrical power to the drive assembly to move the movable barrier. The drive circuit power module may be selectably turned on and off to improve efficiency of power consumption by turning off during periods of lowered demand.

A modular garage door opener system and method including a garage door opener having a motor that is configured to be coupled to a garage door to open and close the garage door. The garage door opener includes a first accessory port including a first accessory mounting interface and a second accessory port disposed on the garage door opener including a second accessory mounting interface. An accessory device including a first mounting interface engages the first accessory mounting interface to couple the accessory device to the first accessory port. The accessory device may be disengaged from the first accessory mounting interface and then engage the second accessory mounting interface to couple the accessory device to the second accessory port. Additionally, a second accessory device may engage the first accessory port after disengagement of the accessory device.

In one embodiment, an electronically controlled hatch system for safe ingress, egress, hazard detection, and methods thereof are provided to reduce or eliminate hazards to personnel, including protection of people above and below a scuttle hatch, access port, skylight or elevated deck. Said hatch system reduces the risk of falls while ascending or descending a ladder through an access port. In certain embodiments, severe weather, hazard, security, and other safety information are detected and transmitted to a central control unit for processing and regulating the opening and closing of a hatch covering the access port and/or raising and lowering a safety railing system based on said information and/or user input. Said hatch system may include an actuator and guides for automatically locking/unlocking and opening/closing a hatch, an actuator and guides for automatically raising/lowering a railing system, safety monitoring detectors/apparatuses, and a centralized controller.

A system and portable device are provided for opening and closing sliding doors associated with conventional sliding doors as used in residences and businesses. The portable sliding door device attaches to a sliding door via a bracket, and moves along the same track used by the sliding door. The sliding door device can be initiated to move the sliding door to the open position through remote control, voice-activation, and proximity transmitters. The sliding door device can communicate with wireless routers and be remotely controlled and monitored by computers, netbooks and cell phones. The sliding door device has safety features, including cameras and speakers to ward off attempted break-ins.
