An emergency door closing device that can be installed upon existing doors and hinges to automatically close doors in the response to smoke and fire. The improvements incorporated therein include a hinge cam pivot member that attaches to an existing hinge member of a door and produces a moment force about the existing hinge member allowing a reduced force necessary to pivot the door into a closed position. Further, a novel spring, cam, and lever system is incorporated to activate the moment force to close the door.

An opening-closing member control device includes a motor that opens and closes an opening-closing member of a vehicle, and a control unit configured to stop the motor when determining that a foreign object has been entrapped by the opening-closing member and reverse the motor when a delay time elapses after stopping the motor. When the control unit determines that entrapment has occurred upon operation of a remote operation switch that is separated from the vehicle, the control unit reverses the motor after the delay time that is shorter than when determining that entrapment has occurred upon operation of a vehicle operation switch that is arranged in the vehicle.

Systems and methods for operating an overhead door opener and a lifter are disclosed. The lifter is positioned above the overhead door when the overhead door is in a retracted position and raises and lowers objects along a path that, without care, will intersect with the overhead door. A controller monitors the position of the overhead door and the lifter and moves the overhead door if the lifter is out of the way, and if the lifter is not out of the way the command is not executed to prevent interference between the lifter and the overhead door.

A method, apparatus and system is disclosed for automatically opening and closing a garage door without user intervention. A vehicle-mounted mobile transmitter autonomously and continuously transmits a repeating signal pattern when power is applied to the transmitter as a vehicle is started by a user. A movable barrier gateway device receives the signals from the mobile transmitter and compares an identification code contained in each of the signals to an identification code stored in memory. When a match is found, the movable barrier gateway device sends a signal to a movable barrier controller to open the garage door, and keep the door open as long as the movable barrier gateway continues to receive the signals from the mobile transmitter.

A method and apparatus relating to generating, by at least one motion sensor of a data acquisition device that is mounted to a door having a door closer, motion data indicative of motion as the door is moved from an open position to a closed position, generating, by at least one load cell of the data acquisition device, load data as the door is being opened, analyzing the motion data and load data by a central processing device, determining at least one adjustment to the door closer based on at least one of a duration the door was in each of a plurality of door movement zones, as determined using the motion data, and a force applied to open the door, as determined using the load data, and displaying at least one installation instruction corresponding with the at least one adjustment on a graphical user interface of the central processing device.

A concealed storage system for storing objects is disclosed. The system has an outer casing having a top portion and an open bottom portion defining a hollow interior of the outer casing, an inner casing securely and movably positioned in the interior of the outer casing, wherein the inner casing comprises one or more compartments for securely storing objects, a top portion and a bottom portion, a pulley system securely and operatively positioned on a top portion of the inner casing, wherein the pulley system moves the inner casing in and out of the outer casing when actuated by a motor from a recessed state and non-recessed state; and a normalized conductive object attached to the bottom portion of the inner casing such that when the inner casing is in its recessed state, the normalized conductive object is flush to a ceiling.

A trolley support system (100) includes at least one intelligent trolley (102) designed for use onboard passenger transportation vehicles such as aircraft. The trolley (102) includes a housing (106) with an internal compartment (108) and a door (110) that provides selective access to the internal compartment. The door is movable between a closed position and an unclosed position. The trolley also includes a control sensor (116) that configured to detect at least one characteristic of the trolley and a visual indicator (122) configured to emit a visual transmission based on the at least one detected characteristic. A trolley node (104) having a controller may be included with the trolley and may be communicatively coupled to the control sensor and the visual indicator.

A power door system for a vehicle including a plurality of power-operated doors is provided. The system includes a passive remote entry device configured to emit a signal to one or more cooperating vehicle receivers and a controller configured to cause the power door system to open the at least one power-operated door when the passive remote entry device signal is received and an individual is detected in a predefined activation zone for a predetermined period of time. The system further includes a vehicle-mounted user detection device. The passive remote entry device may be selected from the group consisting of a key fob, a smart key, a key card, a cellular telephone or smartphone configured with a phone-as-a-key function, a Bluetooth®-activated and vehicle-recognized cellular telephone, a Bluetooth®-activated and vehicle-recognized smartphone, and a Bluetooth®-activated and vehicle-recognized smartwatch. Methods for controlling a power door system for a vehicle are described.

A retrofit module configured for use with a door closer having a pinion. The retrofit module generally includes a case, an output shaft, a motor, and a control assembly. The output shaft is rotatably mounted in the case, and is configured for rotational coupling with the pinion. The motor is mounted to the case, and is operable to rotate the output shaft in a door-opening direction. The control assembly is mounted to the case, and is configured to operate the motor to drive the output shaft in the door-opening direction in response to an actuating signal.

Systems and methods for operating an overhead door opener and a lifter are disclosed. The lifter is positioned above the overhead door when the overhead door is in a retracted position and raises and lowers objects along a path that, without care, will intersect with the overhead door. A controller monitors the position of the overhead door and the lifter and moves the overhead door if the lifter is out of the way, and if the lifter is not out of the way the command is not executed to prevent interference between the lifter and the overhead door.
