This specification relates to the fields of automobile maintenance and device calibration technologies and discloses a position adjustment apparatus and an automobile calibration device. The position adjustment apparatus includes a slide member, a supporting member and an adjustment member. The supporting member is movably mounted at the slide member. One of the slide member and the supporting member includes a rack. The adjustment member includes a gear. The gear is meshed with the rack. When rotating, the gear can drive the rack to move in a preset direction, to enable the supporting member to move in the preset direction with respect to the slide member. By means of the gear engagement between the gear and the rack, the supporting member can move stably and precisely in the preset direction with respect to the slide member, so that the automobile calibration device and an automobile to be calibrated can be aligned conveniently and precisely.

Aspects of the present invention provide a display support arm assembly that includes a proximal housing supporting at least one proximal shaft, a distal housing spaced from the proximal housing and supporting at least one distal shaft, and at least one link extending from the at least one proximal shaft to the at least one distal shaft. The at least one link is coupled for pivotal movement about an axis of the at least one proximal shaft. The display support assembly also includes a gas strut extending between the proximal housing and the distal housing. The gas strut provides substantially constant force throughout a range of the vertical adjustment of the display support arm. The display support assembly further includes at least one torque element associated with either or both of the at least one proximal shaft and the at least one distal shaft.

A flexible and collapsible stand and shoulder rest for a portable electronic device is provided, the stand and shoulder rest comprising a base plate securely attached with a back surface of a portable electronic device and a flexible top plate securely attached with a center portion of the base plate such that one or both end portions of the top plate can bend away from the base plate into a curved position, the end portions secured in the curved position by slidable support mounts which slide out from the base plate as the top plate bends into the curved position.

In one aspect, a TV set is provided. A base includes two supporting mounts. One end of the first supporting mount is rotatably connected with a back side of a display screen assembly. The second supporting mount includes two supporting arms symmetrically disposed on two sides of the first supporting mount. One end of each supporting arm is rotatably connected with the first supporting mount respectively at a rotatory connection point. When the base is in a supporting state, for each supporting arm, a triangular supporting structure is formed by the rotatory connection point, the other end of the first supporting mount, and the other end of the supporting arm. When the base is in a retracted state, the first supporting mount is attached to the back side of the display screen assembly, and the second supporting mount is superimposed on an outer side wall of the first supporting mount.

A computerized imaging system and method for creating a 3D imaging dataset of an object are disclosed. The computerized imaging system includes an object stage mounted on a system base plate, the object stage is configured to rotate 360 degrees around its axis perpendicular to the base plate plane. The computerized imaging system includes an elongated elevation arm positioned alongside the object stage, wherein the elongated elevation arm having an image sensor, at least one lens, and a mirror mounted thereon, and wherein the optical axis of the image sensor is parallel to the elongated elevation arm elevation axis. The image sensor is used to capture a plurality of images of the object in a plurality of rotation and elevation angles of the object stage and elongated elevation arm.

A rotatable base stand with a rotatable powering source that includes a lower base body, an electrical body plug for powering the rotatable base, an upper base body with a top surface defining an extension outlet port and with an extension electrical outlet coupled thereto, wherein the extension electrical outlet has outlet ports, is disposed within the extension outlet port, is oriented in a longitudinal direction, and is operably configured to electrically couple with the electrical body plug. The stand also includes an electrical extension plug electrically coupled to the extension electrical outlet and operably to provide power to objects supported by the base stand. The base stand also includes a bearing assembly and a motor that is operably coupled to the upper base body and operably configured to selectively rotate the upper base body 360° along a base rotation path with respect to the lower base body.

A mounting system includes a double-beam support structure comprising two parallel, horizontal bars spaced apart vertically, and a bracket designed to hang from the double support bars while resisting rotation about the support bars. The bracket is slidably positionable along the support bars and may further include a releasable clamp jaw for clamping one of the support bars to selectively fix the position of the bracket along the support bars. The bracket may support a mounting assembly for an electronic visual display, an extension boom assembly, or another item.

Provided is an angle adjustable microscope holder. The angle adjustable microscope holder comprises a base. The base is provided with a rotating piece, the rotating piece is detachably connected with a lifting rod, the lifting rod rotates along with the rotating piece, the lifting rod is provided with a spur rack, the lifting rod is connected with a moving piece in a sleeved manner, the moving piece is provided with a fixing ring, and the fixing ring is configured to fix a microscope. A part of the moving piece is meshed with the spur rack to drive the moving piece to slide relative to the lifting rod. A cross section of the lifting rod is a special-shaped cross section, and the moving piece fits a contact surface of the lifting rod in shape.

A modular apparatus to enable users to multiply the number of objects being supported by a single trailer hitch receiver which installs into a trailer hitch receiver, which can be connected to an automobile, or which rests independently on stands positioned underneath the apparatus, forming a three dimensional array of interconnected mounting brackets used to support objects above the ground with a plurality of configurations possible wherein the user can vary the width, length and height of the array by adjusting the modular components within the limits of the modular component.

The present de-icing apparatus provides relatively small, portable, and adjustable devices for the specific purpose of de-icing a relatively small area of surface water for use by outdoor enthusiasts. The anchorable stand provides directional, surface height, and angular adjustment of the de-icing water flow to allow for establishing the preferred de-icing pattern at the water surface. De-icing means the reduction of freezing and the minimization of ice accumulation in a given surface area of the open body of water. The fixed-height vertical member of the anchorable stand provides a 360° adjustment range of output water flow. The adjustable-height vertical member of the anchorable stand provides surface height adjustment of the intake and output water flows. The vertical rotation point or points of the anchorable stand hold the water movement device and provide angular adjustment of the intake and output water flow.
