The present invention relates to a sectional door operator system (1) for opening and closing an opening (2), comprising a door frame (3) comprising a first frame section (4) at a first side (5) of the opening (2) and a second frame section (6) at a second side (7) of the opening (2), a door (8) arranged to be moved between an open (0) and closed (C) position and comprising a plurality of horizontal and interconnected sections (9) connected to the door frame (3) at least a drive unit (10) mounted on a first section (9) of the plurality of sections (9), wherein the drive unit (10) is moveably connected to the first frame section (4) and the drive unit (10) is moveably connected to the second frame section (6), the drive unit (10) comprise at least one motor (11) connected to at least one battery (12) arranged to power the at least one motor (11), and the drive unit (10) is arranged to move the door (8) from the closed position (C) to the open position (0).

A vehicle barrier gate system which is positioned above a roadway through which vehicles pass. Some of the various embodiments of the present disclosure include a gate comprised of an arm and barrier which is adjustable between a raised position in which a vehicle may pass and a lowered position in which a vehicle is prevented from passing. The gate may be movably connected to a ceiling or an overhead support structure positioned above the roadway. Various types of actuators may be utilized to adjust the gate along a linear and/or angular path between the raised and lowered positions. A control unit may be in communication with one or more sensors and/or an authorization system to control the actuator. The gate may include a breakaway mechanism which allows the gate to be manually raised or lowered in the event of actuator failure or a vehicle ramming through the gate.

A safety device (200) is provided for a movable barrier system ((100). The safety device comprises a position sensor (210) mountable, in use, to or adjacent a barrier (110). A target (220) is mountable to the other of the barrier, such that movement of the barrier causes relative movement between the position sensor and the target. A controller (240) can communicate with the position sensor. The position sensor can detect movement of the target relative to the position sensor and output a signal to the controller. The controller can receive the output signal from the position sensor, determine one or more signal characteristics from the output signal, and compare the one or more determined signal characteristics with one or more predetermined signal characteristics to determine if the relative movement between the target and the position sensor is within a predefined range. A movement detection method is also provided.

Systems and associated methods for controlling operation of loading dock equipment are disclosed herein. In some embodiments, the system and associated methods can be used to control operation of loading dock equipment (e.g., a vehicle restraint, a dock door, a dock leveler, etc.) according to a preset sequence of operations. The system can include a display screen that sequentially presents a series of graphical control elements (e.g., touch-sensitive buttons) that enable operation of the loading dock equipment in an appropriate sequence. Additionally, the visual appearance and/or sequence of presentation of the graphical control elements indicate the proper sequence of selection to the user, thereby reducing user confusion and simplifying the operation of the loading dock equipment.

A sliding door assembly includes a door frame with a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill, and a primary sliding panel secured in the door frame. The top trim member includes a track configured to support a weight of the primary sliding panel and prevent the primary sliding panel from coming off the track. Other features include an interlock mechanism to limit relative movement using multiple sliding doors and a brake mechanism to secure the doors in position when the door handle is released. A drop window includes features to accommodate for manufacturing tolerances and box frame assemblies that are out of square.

This vehicle lid device includes: a box provided on a vehicle-body deep side and having an opening for exposing a storage space to a vehicle-body outside; a lid to open/close between opening-closed/opened positions; and an open/close mechanism to open/close the lid between the closed/opened positions. The open/close mechanism includes a rotary gear rotatable about a rotation axis extending along a vehicle-body back surface on the vehicle-body deep side, a slide member provided on the vehicle-body deep side, meshed with the rotary gear, and slidable along the vehicle-body back surface through rotation of the rotary gear, a first guide mechanism to move the lid in a vehicle-body front-back direction relative to the box by the slide member sliding in a first region section, and a second guide mechanism to move the lid along the vehicle-body back surface relative to the box by the slide member sliding in a second region section.

A mechanism is disclosed for automating a sliding window having window components comprising a stationary pane component, a sliding pane component and a window frame component. The mechanism includes a telescoping mounting assembly attached to a first of the window components. The telescoping mounting assembly includes a housing and one or two extension arms, selectively extensible from the housing to either one or both sides of the first window component. A motor is disposed within the housing driving a first gear. Either one or two telescoping drive shafts are disposed within the extension arms, each having a gear on one end of the telescoping drive shaft driven by the first gear and having a gear on an opposite end of the telescoping drive shaft that engages a rack mounted on one side of a second of the window components. The telescoping drive shafts are coupled to the extension arms and are therefore selectively extensible with first extension arms. This mechanism is installed by extending the extension arm to fit the first of the window components. The sliding window is opened and closed by rotation of the motor and the telescoping drive.
