The present invention provides a monitoring system for cargo carrying vehicle including a container/trailer including at least one door, a door sensing device for monitoring the open or closed status of the door(s), a cellular communications device wirelessly transmitting information to one or more remote facilities/sites include the status of the door(s) as monitored by the door status sensor, telemetry device to identify the position of the cargo container and cargo sensing device to obtain information about contents in the interior of the cargo container. Further, embodiment of the present invention provides that fingerprint of the door opening and closing can be measured from the 3 sensors (i.e. accelerometer, compass and gyroscope) can be stored in the microprocessor onboard in the monitoring apparatus.

A device for manually and/or electromotively adjusting or securing a first vehicle part and a second vehicle part relative to each other is provided. The device comprising an adjustment part which has a joint for pivotable arrangement on the first vehicle part, wherein the adjustment part is to be arranged on the first vehicle part in such a manner that, when the vehicle parts are adjusted relative to each other, the adjustment part moves relative to the second vehicle part, an output element which is to be arranged on the second vehicle part, is operatively connected to the adjustment part and is drivable in order to move the adjustment part relative to the second vehicle part, a shaft connected to the output element, and a flexible force transmission element which is fastened at a first end and at a second end to the adjustment part.

A motorized door opening device, including: a) a wheel actuator coupled between a door and at least one wheel, configured to lower said at least one wheel to a surface in response to a wheel lowering signal; b) an electric motor including a rotor coupled to rotate said at least one wheel; and c) a door attachment member configured to attach said motorized door opening device to the bottom part of said door; whereby rotation of said motor after lowering of said at least one wheel causes said wheel to rotate in contact with said surface and move said door.

An electronic lock device according to one embodiment includes a first magnetometer, a second magnetometer, a dynamic ferromagnetic component positioned between the first magnetometer and the second magnetometer, a processor, and a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the electronic lock device to read sensor data from the first magnetometer and the second magnetometer, modify the sensor data to generate compensated sensor data that compensates for magnetic noise generated by the dynamic ferromagnetic component, and determine whether the door is in a closed state or an open state based on the compensated sensor data.

Methods and systems are described for determining operation of an openable barrier and direction of movement of a person through an opening controlled by the barrier. A method includes detecting with a hinge sensor a closed position for the barrier, the hinge sensor being mounted to a hinge of the barrier, determining with the hinge sensor when the barrier changes position from the closed position to an open position, detecting with at least one motion sensor motion of an object in proximity to the opening, and determining a direction of movement of the object through the opening based on whether the motion is detected before or after detecting the change in position of the barrier.

A vehicle includes a liftgate system for preventing a garage door from closing on an open-liftgate. The liftgate system includes a liftgate and a processor. The liftgate includes an external-facing sensor. The processor is to, when a garage door is open, determine whether the liftgate is in a closing path of the garage door When the liftgate is in the closing path, the processor causes the liftgate to be lowered to an intermediate position between fully open and fully closed.

A method for operating a building closure having the shape of an overhead sectional door or of a garage door including at least one spring-loaded counterweight device and an electrical drive device is disclosed. A control unit simultaneously monitors the position of the building closure and a motor current for the drive device. When the building closure is in an open or a closed position, the motor current is reduced and maintained at a level to residually energize the drive device to reliably maintain the building closure in a desired position.

Methods and systems are described for determining operation of an openable barrier and direction of movement of a person through an opening controlled by the barrier. A method includes detecting with a hinge sensor a closed position for the barrier, the hinge sensor being mounted to a hinge of the barrier, determining with the hinge sensor when the barrier changes position from the closed position to an open position, detecting with at least one motion sensor motion of an object in proximity to the opening, and determining a direction of movement of the object through the opening based on whether the motion is detected before or after detecting the change in position of the barrier.

A refrigerator includes: a cabinet in which a storage compartment is formed; a refrigerator door for opening and closing the storage compartment; a rack which can move from an initial position to a door opening position to open the refrigerator door; a driving motor which generates a driving force to move the rack; a power transmission unit which transmits power of the driving motor to the rack; a rotation detection unit which detects a rotation number of the driving motor; and a controller that controls the driving motor based on information on the rotation number detected by the rotation detection unit, in which the controller may control the driving motor to a first state until the rack moves from the door opening position to a reference position and may control the driving motor to a second state until the rack moves from the reference position to the initial position.

A door closer assembly for an entryway device having a position sensor that assists in determining the location of the door closer assembly, and thus the location of the associated entryway device, relative to at least an entryway. The position sensor can be coupled to, and/or part of, the door closer assembly. Information obtained by the position sensor may be used by one or processing devices of an access control system to determine whether the door closer assembly and/or the entryway device is at the closed location, among other locations, as well as the direction(s) of displacement of the entryway device. Such information may be utilized in calibrating other devices, as well as determining the occurrence of a number of events, including unauthorized displacement or holding of the entryway device. A timer may also be utilized to further evaluate the nature of the displacement of the entryway device.
