A vertical protective device for a medical display hanger comprises a contact piece (1), a microswitch (2), a rotating shaft (3) and a vertical protective plate (4), wherein the contact piece (1) is connected to one end of the rotating shaft (3), the vertical protective plate (4) is connected to the other end of the rotating shaft (3), and the microswitch (2) is arranged on a microswitch support (10); and when a collision of the vertical protective plate (4) happens, the rotating shaft (3) drives the contact piece (1) to rotate, and the contact piece (1) triggers the microswitch (2), so as to control the medical display hanger (30) to stop moving or immediately rise. When an accidental collision of the medical display hanger (30) happens in a substantially vertical direction, the medical display hanger (30) can effectively come to an emergency stop or avoid.

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).

A fixture that is configured to hold a mobile device for calibrating an electronic display screen includes an adjustable arm, a controller including a processor, one or more motors, one or more suction cups configured to attach the fixture to the electronic display screen, one or more brackets, attached to the arm, to hold the mobile device such that the camera of the mobile device points towards the electronic display screen. The processor of the controller is configured to receive one or more signals from the mobile device to move the adjustable arm to point the camera of the mobile device towards a point on the electronic display screen, and in response to receiving the signals from the mobile device, send one or more signals to the motors to move the adjustable arm to point the camera of the mobile device towards the point on the electronic display screen.

A mounting system capable of mounting objects to support structures is disclosed. The mounting system includes a wall mount including a display bracket configured to hold the object, a fixed support bracket couplable to a vertical support structure, and a linkage assembly. The linkage assembly has a low-profile stowed configuration in which the object is held in a raised position close to the support structure. The linkage assembly moves to another configuration to move the object. The object can be held in a lowered position. A biasing mechanism can facilitate convenient movement of the object.
