The present disclosure discloses a calibration device for a vehicle Advanced Driver Assistant System, the calibration device includes: a foldable base (1), a stand assembly (2) and a beam assembly (3); the foldable base (1) including a bearing seat (11) and a plurality of bearing arms (12) rotatably arranged on the bearing seat (11), the stand assembly (2) is disposed on the bearing seat (11); the bearing arms (12) are able to be folded relative to the bearing seat (11) in a direction approaching the stand assembly (2); the beam assembly (3) is disposed on a top of the stand assembly (2) and includes two foldable beams (32). The calibration device for the vehicle ADAS can be folded when it is not in use, so that it occupy a smaller space and is convenient to carry, thereby facilitating its storage and transportation.

A display stand has two spaced apart legs connected by a horizontal support bar that is attachable to multiple displays. Carriage assemblies allow the stand to adjust the vertical position of the displays, shuttles and rails allow the stand to adjust the horizontal positions of the displays, and a central joint on the support bar allows the stand to adjust the angle between the displays. The carriage assemblies can convert rotational movement of adjustment handles into vertical movement of the support bar that is synchronized at both legs whether the support bar is in a straight or angled configuration. Wheels on the shuttles can provide smooth, consistent contact with rails in the support bar despite changes in the nominal dimensions of the rails. The display stand provides improved smoothness, rigidity, and comfort for the user to support and use multiple displays on a single stand.

A camera mount assembly for holding a camera or other perception sensor that may be fixed with respect to a ground plane and used for incremental angle measurement of the camera or other perception sensor in three axes, such that the precise spatial relationships of imaged objects with respect to the orientation/position of the camera or other perception sensor may be determined. A base structure of the camera mount assembly may be affixed to a fixed or moveable support structure and multiple leveling devices and/or laser devices are provided to establish a reliable reference relative to the ground plane. Thus, the exact orientation of the camera or other perception sensor in space may be determined frame to frame, such that the precise orientation of imaged objects with respect to the orientation/position of the camera or other perception sensor relative to the ground plane may be determined over time.

A phone gravity holder comprises a base, a pull rod configured to hold the phone, and a left clamping arm and a right clamping arm configured to clamp the phone, wherein the base is provided with a positioning shaft, the left clamping arm and the right clamping arm are both mounted on the positioning shaft in a rotatable manner, and the pull rod is respectively in transmission connection with the left clamping arm and the right clamping arm, respectively. When the phone is used, the phone is directly placed on the pull rod, and under the gravity effect of the phone, the pull rod drives the left clamping arm and the right clamping arm to rotate in reverse to clamp the phone. The phone can be clamped automatically by utilizing the gravity of the phone and simple mechanical principles, the structure is simple, and the production cost is greatly reduced.

Provided is a display apparatus including an image forming device configured to form an image, an optical system configured to provide an output image by combining light containing an outside landscape with the image formed by the image forming device, and a driving device configured to adjust a distance between the image forming device and the optical system, wherein the driving device includes a fixed frame, a movable frame which faces the fixed frame and is movable, an actuator configured to change a distance between the fixed frame and the movable frame, and a fixing member configured to fix the distance between the fixed frame and the movable frame, wherein the image forming device is fixed to the movable frame.

Disclosed is a customizable in-ground stand that retains its position in response to off-center, leaning, and/or top-heavy forces imposed onto it by a retained object. The stand includes an elongated tube. The stand includes an interchangeable retention ring with a downward extension that attaches to a top of the elongated tube, and with a length of tube that extends laterally in front of the elongated tube as an incomplete ring from the downward extension. The stand further includes an interchangeable base with a rod that attaches to a bottom of the elongated tube, and with support members that extend outwards from each side of the rod. Each of the support members has a vertical triangular plate that extends perpendicularly from the rod and that narrows to a particular point towards a bottom of the rod, and a lip that extends perpendicularly over each vertical triangular plate.

Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

A device for holding an audio microphone is disclosed. The microphone holding device includes a base section having a base plate connected to a riser block that engages with a tube of a microphone holding section to enable rotation of the microphone holding section from a horizontal orientation to a vertical orientation. The device also includes an expander shaft section including an expander shaft coupled at one end with the tube and at another end with base plate. The expander shaft expands from a compressed shaft to an expanded shaft when the microphone holding section rotates from the horizontal orientation to the vertical orientation to assist in holding the microphone holding section in the vertical orientation.
