A universal quick-release vacuum connector includes a base removably attachable to an object. A vacuum formation-and-release actuator includes a movable anchor member that establishes a releasable vacuum connection with a reference surface. The anchor member includes a flexible outer seal member, a central hub integrally formed with the flexible outer seal member, and a vent port extending through the central hub. A vent port closure member closes or assists in closing a vent port inner end depending on the position of the anchor member relative to the base to establish a controlled pressure zone that maintains a negative pressure differential relative to an external ambient pressure. The releasable vacuum connection is releasable by virtue of the anchor member and the base being movable relative to each other in a manner that vents the controlled pressure zone while the base remains attached to the object.

A tractor assembly and an elevator. The tractor assembly includes: a traction sheave, having a traction means fitting surface and a first transmission surface on a peripheral surface thereof; a plurality of support wheels, configured to support the traction sheave, and each having a second transmission surface on a peripheral surface thereof; and support wheel bases, configured to support the support wheels through support shafts, wherein the first transmission surface of the traction sheave is in transmitting cooperation with the second transmission surfaces of the plurality of support wheels respectively. According to the tractor assembly and elevator of the present application, the support wheels are disposed to achieve the transmitting cooperation of the traction sheave during operation of the elevator and support the traction sheave, thus omitting the load and drive bearings required by a conventional traction sheave.

Provided are a detection device and a control device of a lifting platform thereof, wherein the control device is used for controlling the lifting platform of the detection device, wherein the control device comprises a first distance measuring sensor arranged on the top of the detection device; a first processor connected with the first distance measuring sensor and used for obtaining a first distance measurement instruction and controlling the first distance measuring sensor to measure a first distance between the top of the detection device and an obstacle directly above the detection device according to the first distance measurement instruction; the first processor is further used for obtaining the first distance sent by the first distance measuring sensor, generating an elevation instruction according to the first distance, and controlling a lifting motor of the detection device to drive the lifting platform to rise to the target position.

Disclosed are a calibration system (600a) and a calibration support (100a) therefor. The calibration support (100a) comprises: a base (10); a vertical frame assembly (20a), comprising a fixed vertical rod (22) and a movable vertical rod (24), wherein the fixed vertical rod (22) is mounted on the base (10), and the movable vertical rod (24) is capable of moving, within a preset range relative to the base (10), in the length direction of the fixed vertical rod (22); and a cross beam (30a), which is detachably mounted to one of a first mounting seat (35a) and a second mounting seat (36a) which are connected to the movable vertical rod (24), the cross beam (30a) being used for mounting a calibration element, and the calibration element being used for calibrating an advanced driver assistant system of a vehicle. The position of the first mounting seat (35a) is higher than the position of the second mounting seat (36a); and when moving relative to the base (10) in the length direction of the fixed vertical rod (22), the movable vertical rod (24) drives the first mounting seat (35a) and the second mounting seat (36a) to move relative to the base (10) in the length direction of the fixed vertical rod (22).

An apparatus for engaging equipment to a support includes a member defining a first channel having a first side wall capable of lateral movement with respect to a second side wall suitable for engaging the equipment therebetween. The member defines a pair of surfaces suitable for engaging equipment thereon. A movable member is capable of causing the lateral movement. A substantially compressible member is operably interconnected between the movable member and the first side wall. A pin is selectively raisable with respect to one of the surfaces within a peripheral area defined by the one of the surfaces.

The present invention provides a bracket fixable to a desk edge, the bracket including: a fixing portion, a holding portion and a connecting assembly, wherein the connecting assembly has one end connected to the fixing portion and the other end connected to the holding portion; the connecting assembly includes a connecting body, having a first end and a second end, a first connecting member arranged at the first end, and a second connecting member arranged at the second end; the first connecting member has a first body portion perpendicular to the connecting body, and a first locking portion fixed to the fixing portion; the first body portion is provided with a first arc-shaped slot; the second connecting member has a second body portion perpendicular to the connecting body, and a second locking portion fixed to the holding portion; the second body part is provided with a second arc-shaped slot; and the connecting assembly further includes a first screw slidable in the first arc-shaped slot, and a second screw slidable in the second arc-shaped slot.

A display apparatus includes an at least partially deformable display, an at least partially deformable apron, the apron is coupled to the display and moves in a vertical direction to change an externally exposed area thereof, a housing for accommodating at least a portion of each of the display and the apron, a base coupled to the housing, a guide having a first end mounted on the apron and a second end mounted on the base, the guide moves the display and the apron in the vertical direction to change an externally exposed area of each of the display and the apron, and a moving supporter having a first end mounted on the apron to move in the vertical direction and a second end mounted on the base to move in a lateral direction with respect to the base.

A quick detach connector for an imaging device.

A display device includes a main body configured to have a display module to which a user interface is output, a bending module located at a center of a back surface of the main body, and a controller. The controller controls the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module. Then, the controller changes at least one of a size and a position of a display region to which the user interface is output, according to whether a mode is the flat mode, the first bending mode, or the second bending mode.
