A system can include a display assembly that includes a display, a display side, a back side and a frame, where the back side includes a serial bus socket; and a camera assembly that includes a camera head unit coupled to an end of an arm, where an opposing end of the arm includes a serial bus connector receivable by the serial bus socket of the back side of the display assembly.

A calibration bracket (100), comprising: a base (10); a stand component (20) connected to the base (10); a cross beam component (30, 30′) mounted to the stand component (20) and used for mounting a calibration element, which is used for calibrating an advanced driver assistant system of a vehicle; and a rotating component (40) mounted between the stand component (20) and the base (10), and used for driving the stand component (20) to pivot about a central axis of the stand component (20) relative to the base (10) so as to adjust an angle of rotation of the cross beam component (30, 30) relative to the central axis of the stand component (20). According to the structure, an angle of rotation of the cross beam component (30, 30′) relative to the central axis of the stand component (20) can be adjusted, so that the rotation of the cross beam component (30, 30′) is free from the mounting position. The calibration bracket is simple in structure, and convenient to carry.

The present disclosure relates to an ultrasonic imaging apparatus that has a tolerance for easy assembly and reduces shaking and noise by reducing the tolerance after assembly. The ultrasonic imaging apparatus includes a main body, a probe connected to the main body to irradiate and receive ultrasonic waves and to transmit the ultrasonic signals to the main body, a control panel configured to control the main body or the probe, and a moving device configured to connect the control panel and the main body and to move the control panel with respect to the main body in the upward and downward directions, wherein the moving device includes a housing fixed to the main body, a moving member configured to be movable with respect to the housing in the upward and downward directions, and a regulating bearing installed in the housing and configured to assist the upward and downward movement of the moving member by coming into rolling contact with the moving member and to regulate a gap with the moving member.

A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

A lift apparatus and method of use thereof for securing a garden device and moving the garden device between a lowered position and a lifted position are provided. The lift apparatus broadly includes a base, a lift rod, and a universal mounting plate. The base is configured to be secured in a position on a ground surface. The lift rod is removably coupled to and extends outwardly away from the base. Further, the lift rod is configured to alternatively operate to move the garden device between the lowered position and the lifted position. The universal mounting plate is removably coupled to the lift rod at an end of the lift rod opposite that of the base. Further, the mounting plate includes engagement pins configured to interface with elongated slots to secure the garden device to the mounting plate.

A surveillance equipment platform mounting in an interior cabin of a vehicle. The interior cabin of the vehicle has a roof with an opening. The surveillance equipment platform includes a retractable telescoping structure having surveillance equipment mounted so as to extend through the opening of the roof, and to fully retract into the interior cabin. The surveillance equipment platform also includes a sealing device that mounts to the retractable telescoping structure below the surveillance equipment and oriented parallel to the roof of the interior cabin. The sealing device includes an elastically deformable gasket that elastically deforms during travel of the sealing device through the roof of the interior cabin when the surveillance equipment extends through the opening in the roof during extension of the retractable telescoping structure, and when the surveillance equipment retracts into the interior cabin during retraction of the retractable telescoping structure.
