A gate opening apparatus includes an external housing, a main chassis, a motor device, a driving rotor, a plurality of guiding rollers, a transmission chain connecting the driving rotor, the guiding rollers and a door gate, and a gate actuating arrangement. The gate actuating arrangement includes a clutching device supported on the main chassis and connected to the motor device, a limit switch assembly coupled to the clutching device, and a control module. The gate opening apparatus is arranged to operate between a power mode and a manual mode. In the power mode, the clutching device is engaged with the driving rotor for driving a movement thereof by the motor device so as to selectively open and close the door gate. In the manual mode, the clutching device is disengaged from the driving rotor so that the driving rotor is adapted for being rotated manually.

A mechanism for opening and closing an overhead door includes a drive loop coupled to the overhead door, a motor with a drive shaft and a drive wheel for driving the drive loop. A one-way bearing couples the drive shaft to the drive wheel, which one-way bearing is configured to transmit torque from the motor to the drive wheel, as the motor rotates the drive shaft in a first rotational direction to raise the overhead door, and configured so that torque is not transmitted to the drive wheel as the motor rotates the drive shaft in a second rotational direction opposite the first rotational direction. As a result, the motor applies torque through the one-way bearing to raise the overhead door and to support the weight of the overhead door while lowering the overhead door.

A chain support mechanism for use with an openable frame component and a method of using such a chain support is provided, where a chain actuator is provided in a housing, the chain actuator including a push-pull chain which chain can bend in one direction only, the housing mounted with its longitudinal extent along one frame component with the chain attached to the openable frame component where the chain actuator may be manipulated to extend or withdraw the chain from the housing, thereby moving the openable frame component, and where the chain support mechanism includes a first arm pivotably fastened to the housing and a second arm pivotably fastened to the openable frame component, where the distal end of the first arm and the distal end of the second arm are pivotably connected by a sliding member, against which sliding member the chain may slide.

A system for controlling one or more motorized windows is described herein. The motorized windows each have a processor, a network device and wireless transmitters enabling connection via a network. The network is controlled by one or more mobile devices which receive user input. The mobile devices wirelessly connect to a local area network (LAN) via a hub. One or more hubs are connected via the LAN. The motorized windows are networked via a personal area network (PAN). The hubs convert the LAN protocol to the PAN protocol. Sensors send sensor data along with real time weather data to the processor. The processor uses this sensor data to update charts and schedules in memory, then sends commands to the controller based on these updated charts and schedules according to user defined and factory set parameters. The system includes both local and cloud-based control.

An automated window system is described herein. The system includes one or more motorized windows and includes both local and cloud-based control facilitated by motors or actuators in each motorized window that are actuated by a controller. Each motorized window further includes a processor with settings stored in memory that direct the controller. Sensors send both local and remote sensor data along with real time weather data to the processor. The processor uses this sensor data to update charts and schedules in memory, then sends commands to the controller based on these updated charts and schedules according to user defined and factory set parameters. Additionally, the motorized windows each have a network device and wireless transmitters enabling connection via a mesh network, the network controlled by one or more mobile devices which receive user input.

An automated window mechanism is disclosed. The automated window mechanism includes an electrically powered actuator configured to move a slidable window between a closed position and an open position, a power source, and two or more sensors. The sensors generate signals related to a different environmental condition. The mechanism also includes a controller adapted to receive signals from the two or more sensors and operate the actuator to move the slidable window to an open or closed position as appropriate.

A domestic appliance, for example a washing machine, comprises a body having an access opening to a process chamber arranged inside the body, a door which is movably attached to the body and which closes the access opening in a closed position, a door-closing mechanism for holding the door closed in its closed position and a door-opening mechanism arranged on the body or on the door, having a push slider, which is movable between a retracted position and a deployed position, and a drive unit for driving the push slider. A transfer of the push slider out of the retracted position into the deployed position effects opening of the closed door, the push slider acts in a pressure-exerting manner on the door or on the body and thereby overcomes a holding-closed action of the door-closing mechanism and opens the closed door.

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

A cover system for covering a vehicle tow hitch connector includes at least a first retention member including a first retention slot, and a first door support coupled to the first retention member. A second door support is positioned opposite the first door support. A door is rotatably coupled to the first and second door supports. The door includes a first retention projection structured to be received in the first retention slot to position the door in a closed orientation.

An electronically powered window for a watercraft consists of a shuttle frame, a sliding mechanism, a window pane, and a bottom edge support groove. A first lateral support arm and a second lateral support arm of the shuttle frame along with the bottom edge support groove helps position the window pane within the shuttle frame. The sliding mechanism allows the user to position the window pane such that the window is in an open configuration or a closed configuration. To do so, a first lateral edge is slidably positioned along the first lateral support arm. Moreover, a second lateral edge is slidably positioned along the second lateral support arm.
