An apparatus comprising a baseplate configured to be coupled to a door configured to be positioned in an open door position, a closed door position, and a plurality of door positions in between the open position and closed position; a motor; a circuitry electrically coupled to the motor and configured to be in communication with a remote computing device; at least one proximity sensor electrically coupled to the circuitry and configured to determine the door position with respect to a door frame; a drive wheel coupled to the motor and the circuitry, the drive wheel comprising an external surface, the external surface of the drive wheel configured to rotatably contact a ground surface; and wherein the motor is configured to be remotely activated by the remote computing device to engage the drive wheel to rotatably contact the ground surface to reposition the door responsive to receipt of a signal.

A landing gear system controller for controlling a landing gear system of an aircraft. The controller is configured to receive a request to operate a non-landing gear system element of the aircraft, and to cause operation of at least part of the landing gear system of the aircraft during a take-off or landing procedure on the basis of the request.

A second step of opening a closed openable/closable roof starts before a first step of opening a closed storage compartment cover finishes, so that a distance between portions of the storage compartment cover and the openable/closable roof facing each other is shorter at a point in time when the storage compartment cover is fully opened in the first step than at any other point in time. A fifth step of closing the open openable/closable roof starts before a fourth step of opening the closed storage compartment cover finishes, so that a distance between portions of the storage compartment cover and the openable/closable roof facing each other is shorter at a point in time when the storage compartment cover is fully opened in the fourth step than at any other point in time.

An intelligent hinge determines motions of a swinging door. The hinge has an accelerometer secured to a leaf of the hinge. As the door swings, the leaf also rotates and the accelerometer determines an acceleration value. A velocity of the swinging door may be determined from the acceleration value. An initial, instantaneous, and final angular position of the door may also be determined from the acceleration value.

A vehicle rear door control system includes a vehicle rear door, a keyfob sensor array, a movement detection sensor, a projector and an electronic controller. The keyfob sensor array is configured to detect proximity of an individual with an authorized keyfob. The movement detection sensor installed to the vehicle below the rear door. The projector installed proximate the rear door and aimed to project images to a ground surface rearward of the vehicle proximate the rear door. The electronic controller controls opening operation of the rear door in response to detection of the authorized keyfob and detection of a conforming gesture detected by the movement detection sensor. The electronic controller is further configured to operate the projector to project a position image to the ground surface alerting the individual to stand rearward of a portion of the positioning image during opening of the rear door.

A parcel receptacle includes a bottom member, an exterior wall that extends upward from the bottom member and that defines an interior space, and a top member that is coupled with the exterior wall and configured to cover an opening of the receptacle to enclose the parcel within the interior space. The parcel receptacle also includes a lock mechanism that is operably coupled with the top member and the exterior wall. The lock mechanism is lockable to prevent user access to the interior space and is unlockable to enable the top member to be opened to allow user access to the interior space. A vertical lip of the top member overlaps at least a portion of the exterior wall so that a seam between the top member and the exterior wall is covered by the vertical lip.

An electricity supply relay circuit for relaying electricity supplied from a sub-battery to a plurality of loads to which electricity is supplied from a main battery provided in a vehicle, the electricity supply relay circuit including: a plurality of switches corresponding to the loads; an electricity receiving wire connecting the switches to the sub-battery; a plurality of electricity supply wires corresponding to the loads via which electricity is supplied from the switches to the corresponding loads; and a control circuit that turns on the switches when a voltage of the main battery is lower than a predetermined first threshold.

A refrigerator includes a casing including storage compartments, doors attached to the casing to expose or cover the storage compartments, hinges connecting the doors to the casing and supporting the doors so that the doors are openable and closable, electrically non-conductive hinge covers detachably attached to the casing and covering the hinges, and a wireless adapter disposed on the hinge cover and including an antenna unit configured to transmit and receive radio waves.

An apparatus comprising a baseplate configured to be coupled to a door configured to be positioned in an open door position, a closed door position, and a plurality of door positions in between the open position and closed position; a motor; a circuitry electrically coupled to the motor and configured to be in communication with a remote computing device; at least one proximity sensor electrically coupled to the circuitry and configured to determine the door position with respect to a door frame; a drive wheel coupled to the motor and the circuitry, the drive wheel comprising an external surface, the external surface of the drive wheel configured to rotatably contact a ground surface; and wherein the motor is configured to be remotely activated by the remote computing device to engage the drive wheel to rotatably contact the ground surface to reposition the door responsive to receipt of a signal.
