A profile learning system for cooperative control of a dual actuator applied to opposite sliding doors may include a first position sensor configured to detect a position of a door that operates in a first direction along a rail; a spindle assembly including a spindle that operates in a second direction with respect to the door to prevent the door from rattling; first and second motors engaged to the door and the spindle assembly and configured to provide driving power to the door and the spindle assembly, respectively; a memory unit configured to store the position of the door; and a control unit configured to adjust an output of the second motor configured for a predetermined time period and to determine learning success or learning failure for complete opening or closing of the door based on the position of the door when a stall state is detected due to a difference in stroke between the first motor and the second motor.

A door barricade apparatus includes a body portion having a pushing face, a port, an advancing interface, and a release interface. The apparatus further includes a shaft portion having a shaft and a door bracket. The door bracket has a throat terminating in at least an l-shaped configuration. The door bracket is pivotably coupled to the shaft at a first end and the shaft is disposed within the port.

A device for securing a door including a rotatable handle affixed to the door, a rotatable member affixed to the door, a catch, and a protrusion from the rotatable handle that is configured to lift the member when the member is engaged with the catch and the rotatable handle is rotated. A device for securing a door including a member configured to be rotatably attached to the door, a catch configured to be attached to a wall adjacent to the door and to receive the member, and a protrusion configured to be attached to a handle on the door and to lift the member when the member is in a closed position and the handle is rotated. A method for installing a device for securing a door with a handle, the method including affixing a member to the door so that the member can rotate, affixing a catch to a wall adjacent the door, the catch configured to receive the member, and affixing a protrusion to the handle, the protrusion configured to lift the member when the member is engaged with the catch and the handle is rotated.

Barricade devices and methods of barricading a door are disclosed. Such devices and methods may be used to barricade a door, and thereby prevent an intruder from entering a sheltering space, such as a classroom, storeroom, or hallway. The barricade-device may have a pivotable stop-device that is pivotable from a location adjacent to a door. The pivot-location may be at an elevation that is lower than a door handle on the door. The stop-device may be pivotable from a reserve-position to a stop-position. In the reserve-position, the stop-device does not barricade the door. In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the use of one or more major muscle groups of the body, but need not require precise dexterity of the fingers or hands (e.g. such as that required to manipulate small keys, latches, and/or the grasping and turning of assemblies). As such, the barricade-device may be used properly and quickly by a wide range of people having differing physical and mental capabilities.

In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the application of an activation operation to an activator. A wide range of people having differing physical and mental capabilities may use the barricade-device properly and quickly.

The disclosed computer-implemented method may include receiving sensor data associated with a mobile device associated with a vehicle, wherein the sensor data includes at least one of an angular velocity vector, a linear acceleration vector, and a rotational acceleration vector recorded over a period of time, determining an event signature based on the sensor data, and detecting a door closing event associated with the vehicle based at least in part on the event signature. Other methods, systems, and computer-readable media are disclosed.

A security tube assembly for securing a door in a closed position includes a mounting plate that is mountable to a wall at a point located adjacent to a door in the wall. A bracket is mountable to the wall on an opposite side of the door with respect to the mounting plate. A tube is pivotally coupled to the mounting plate. The tube is positionable in first position having the tube extending downwardly alongside the door to facilitate the door to be opened or closed. Conversely, the tube is positionable in a second position having the tube extending across the door and having the tube resting in the bracket to inhibit the door from opening.

A door lock device includes a door mount comprising a front base plate and a mounting guide coupled to the front base plate, the door mount mountable to a door; and a lock arm assembly comprising an attachment plate and a structure engagement assembly, the attachment plate defining a mounting slot, the mounting guide engaging the mounting slot to mount the lock arm assembly on the door mount, the structure engagement assembly configured to engage a structure surrounding the door to prevent the door from opening.

In structure for attaching, to an openable/closable lid, a lid lock unit including: a base member attached to the lid back side and having a base shaft portion extending in a predetermined direction; a knob member exposed on the lid front side, having a knob shaft portion shaft-fitted to the base shaft portion, and supported by the base member rotatably between a reference position and an opened position about the knob shaft portion; and an open/close mechanism for opening the lid by the knob member rotating from the reference position to the opened position, the base member includes a base extending portion extending in a direction crossing the predetermined direction, from a side opposed to the lid, and the lid includes a lid extending portion extending in the crossing direction from the back side of the lid and located adjacently to a predetermined-direction outer side of the base extending portion.
