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.

An extendible and collapsible stand holds and stores a bowling ball for a bowler during bowling activities. This stand can have a tapered shape from a base up to a seat on which the bowling ball sits. Multiple extension segments can be slidably connected together in this tapered shape and can individually extend and lock to vary or adjust the height of the stand. The seat forming the top of the stand has a concave shape to provide a compatible surface for which the ball will rest. The seat can also have a lighting means for shining light downward onto the stand base and surface supporting the stand. When not in use, the stand height can collapse down for efficient carry by the user.
