An automatic door operator (30) for a swing door assembly (10) having a door leaf (14) rotationally supported by a door frame (12) is disclosed. The automatic door operator has a motor (34) for causing opening of the door leaf (14) with respect to the door frame (12), and a controller (31) being configured for performing different functions (60) of the automatic door operator. The controller (31) is configured to detect (42) a movement of the door leaf (14), not caused by the motor (34), identify (44) a predefined movement matching the detected movement, determine (46), among the different functions, a function (61-A, 61-B) being associated with the predefined movement, and perform (48) the determined function.

An apparatus for setting a gap between a first electrode and a second electrode of a spark plug, encompassing at least a counter-brace, a gap plate, and a plunger, which are disposed along a longitudinal axis; the counter-brace being configured to brace the spark plug; the gap plate being disposed between the counter-brace and the plunger in the direction of the longitudinal axis; the gap plate being configured to be disposed between the first electrode and the second electrode; and the plunger being configured to apply a deformation force in the direction of the longitudinal axis onto the second electrode.

A compact hinge actuating device comprising at least one hinge comprising at least one hinge plate and at least one knuckle. In one embodiment there is at least one sensor and/or fuse element coupled to said at least one hinge and at least one microprocessor coupled to the at least one hinge. There is also at least one drive coupled to the at least one hinge, wherein when the sensor receives input of a condition, and/or the fuse fails then the drive can be actuated. In the electronic version, the microprocessor reads the input as exceeding a minimum threshold value of a predetermined condition, the microprocessor then triggers the at least one drive to close or open the at least one hinge. In at least one embodiment the drive can be a spring, in another embodiment the drive can be a solenoid.

Safety systems for unmanned vehicles are disclosed. An example vehicle includes a housing and a propulsion system supported by the housing. The propulsion system to generate lift. An anti-crash module is coupled to the housing. The anti-crash module has a compressible foam that is to deploy to protect the propulsion system from an impact.

A device for moving a door leaf between an open position and a close position with regard to a door opening in a wall, includes lever kinematics with a lever for assisting the movement of the door leaf. The lever includes a first section and a second section, and a connecting element for accommodating a transmission component configured for transmitting electrical energy and/or data. The device is provided for the connecting element to be rotatably supported at the first section of the lever.

A tower closing apparatus is provided that is configured to simplify the closing of a multi-piece, hinged hydroponic tower. The hydroponic tower closing apparatus utilizes a collection of static and continuously moving components (e.g., motor driven drive rollers, alignment rollers, tower body alignment rollers, face plate manipulation rollers, face closing rollers, etc.) to close a hydroponic tower as it passes through the apparatus. In particular, as the tower is driven through the closing apparatus, a series of face plate manipulation rollers gradually rotate the face plate(s) relative to the tower body, moving the face plate(s) from a fully open position to a partially closed position. Next a series of face closing rollers continue to rotate the face plate(s) from the partially closed position to the fully closed position, forcing the fasteners to latch the face plate(s) into position.

A method of operating a door system includes receiving a signal from a pressure sensor disposed in a sill or a frame of the door system, authenticating the user after receiving the signal, shifting the lock from a locked configured to an unlocked configuration in response to receiving the signal after authenticating the user, and moving the door panel from a closed position to an ajar position in response to receiving the signal.

An automated gate for robotic mowers may include at least two doors that are sized to receive a robotic mower, and it can be installed in any fence to enable the mower to move between the yards on its own. The at least two doors of an automated gate may provide optional capability to lock when not used by the mower and unlock automatically when the mower gets close. By default, the at least two doors may remain unlocked, yet closed, thereby providing a cost-effective solution for customers who do not have to worry about pets. An add-on module may be provided that may add a locking mechanism and triggering mechanism, thereby providing end users with the ability to lock the automated gate completely.
