A garage door opener assembly, for opening and closing a garage door, including: a garage door, wherein the garage door is displaceable between open and closed positions; a motor, wherein the motor drives at least one of a screw shaft, a belt, and a chain and, in turn, a door opener arm secured to the garage door; a battery backup unit, wherein the battery backup unit includes a secondary electrochemical cell in electrical communication with the motor; and a kinetic energy charger, wherein the kinetic energy charger is in electrical communication with the secondary electrochemical cell.

A door closer with an electric motor-assisted closing feature, that may generate its own power to assist in closing, and controls the speed of opening and closing of the door during generation is disclosed. Embodiments of the present disclosure are realized by a motorized door closer that electrically creates a latch boost force for a closing door. The door closer includes a motor disposed to operatively connect to a door so that the door will be moved toward closed when the motor moves, and a position sensor to determine a position of the door. A processor is programmed to exert a closing force on the door in the latch boost region or when it otherwise detects that a motor assist is needed.

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.

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.

A door operator system for opening and closing an opening, comprising a door frame comprising a first frame section and a second frame section on either side the opening. The door is connected to the door frame. A drive unit mounted on the door is moveably connected to first frame section and the second frame section. The drive unit has at least one motor connected to at least one energy storage device arranged to power the at least one motor to move the door from the closed position to the open position. An energy transmitting device is disposed in close proximity to the door and an energy receiving device mounted on the door. The energy transmitting device wirelessly transmits energy to the energy receiving device mounted to the door. The energy receiving device is operatively connected to the at least one energy storage device for charging said energy storage device.

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.

There is disclosed a lift-and-slide handle assembly (10) which includes a drive shaft (28) operatively adapted to couple with a roller actuating assembly of a lift-and-slide roller carriage. The lift-and-slide handle assembly (10) includes an electronic drive assembly (30) operatively adapted to couple with the drive shaft (28) to apply torque to the drive shaft and a manual drive assembly (32) operatively adapted to couple with the drive shaft (28) to apply torque to the drive shaft (28). The lift-and-slide handle assembly (10) further includes an override coupling assembly (34) operatively adapted to decouple the electronic drive assembly (30) from the drive shaft (28) to couple the manual drive assembly (32) to the drive shaft (28).

Embodiments of the present application include a barrier system to control access including but not limited to a body, an arm, an actuator, a power source which may not be connected to mains power, a controller, or the like. The controller may be configured to instruct the actuator to move the arm reversibly between closed and open positions.
