A hinge includes a bearing plate, a linkage mechanism, a shell element, and an elastic element. The linkage mechanism is linked to the bearing plate. The shell element is disposed on the support, is connected to the linkage mechanism and includes a receiving space. The elastic element is disposed in the receiving space and abuts against between the linkage mechanism and the shell element to provide an elastic force. When an external force is applied, the display device and the bearing plate rotate relative to the support between a first position and a second position. The bearing plate is linked to the linkage mechanism to compress or loosen the elastic element, and then the elastic force is changed. When the external force is removed, the display device and the bearing plate can be stopped at once at any position between the first position and the second position.

A positioning apparatus includes: an upper unit that includes a spherical body, a retainer part that retains the spherical body, and an upper plate part provided on the retainer part and adapted to carry a carried object; a lower unit that includes a lower plate part on which the upper unit is mounted and a guide part that marks a region of movement of the upper unit on the lower plate part; and a tilting structure that tilts the region of movement relative to a horizontal plane and guides the upper unit, on which the carried object is not mounted, toward a reference position located on a lower side of a tilt.

A target stand having a base, a vertical beam extending upwardly from the base, a crossbeam, a locking and rotation assembly having a first portion engaged for vertical movement with the vertical beam and a second portion attached to the crossbeam, the first portion attached to the second portion with a pivot bolt, wherein the crossbeam is configured to be disposed in a first locked horizontal position using the locking and rotation assembly, and wherein the crossbeam is rotatable about the pivot bolt to move into a first non-horizontal position.

An extension panel may include a mating surface shaped to interface with a back surface of a clamp that includes a mounting hole corresponding to a bolt slot in the back surface of the clamp to accommodate a single bolt passing through the extension panel and the clamp. The extension panel may also include a pair of flanges projecting outward from the mating surface and positioned to be on either side of the clamp. The extension panel may also include a flat top surface generally parallel and aligned linearly with another flat top surface of a flexible member. The extension flat top surface may be sized to be approximately a same width as the flexible member at a first end of the extension flat top surface proximate the mating surface and may flare out as the extension flat top surface extends away from the flexible member.

Aspects of the invention are directed to adjustable tilt mechanisms (30), e.g., adjustable tilt mechanisms configured for enabling objects to tilt around a tilting axis (101). According to one aspect of the invention, an adjustable tilt mechanism includes a housing (100) that defines a tilt axis and an adjustment axis (103) oriented perpendicular and non-intersecting relative to the tilt axis and a torque adjustment assembly that is at least partially disposed within the housing. The torque adjustment assembly (118) includes an adjuster (130) positioned for rotation about the adjustment axis defined by the housing, a gear (120) positioned for rotation about the tilt axis defined by the housing, and a biasing spring (140) coupled to the gear. The gear being operatively coupled to the adjuster. The housing configured for coupling to an object.

Methods, systems, and devices are described for antenna positioning with an eccentric tilt pointing mechanism. For example, a system in accordance with the present disclosure may include a base structure and an intermediate structure that is rotatably coupled with the base structure about a first axis (e.g., a tilt axis). The system may also include a positioning system that is coupled with the intermediate structure and configured to orient an antenna boresight about at least two angular degrees of freedom with respect to the intermediate structure (e.g., in an elevation-over-azimuth configuration). The system may also include an actuator between the base structure and the intermediate structure that is configured to set, change, or maintain an angle between the base structure and the intermediate structure, which, in some examples, may include a rotation of an eccentric element based on a predicted path of a target device.

Disclosed herein is a bracket for mounting a tablet shaped device.

A projector mount assembly for a sports enclosure includes a frame structure mountable to rear and front cross beams of a sports enclosure, at least one extension bracket secured to the frame structure and mountable to the front cross beam, and a projector mounting arm mounted to the at least one extension bracket and extending forwardly therefrom. The projector mounting arm is adapted to support, and facilitate front-to-back adjustment of, a projector. The projector mounting arm is pivotable relative to the at least one extension bracket to facilitate adjustment of an elevation of the projector.

A binocular adapter including a base and a receiver joined together by a stanchion arm. The receiver being configured to receive a binocular stem in a stem aperture defined by a receiver head. The receiver head configured to rotate relative to a receiver stanchion. The binocular stem including a first and a second end. The first end including a connector configured to connect to a binocular. The second end, distal to the first end, including a stem extension configured to be received by the stem aperture. The second end further including a groove configured to be received in a spring clip disposed on the receiver stanchion for retaining the binocular stem. The receiver head including a fastener for securing the binocular stem within the stem aperture while it is engaged in the spring clip.

An orbital camera system has at least two extensions that extend from a hub to rotate a camera about a hub in a balanced and low vibration manner. In addition, the exemplary orbital camera system is versatile in configuration having extensions with hinges to allow variations in the configuration. The hub may be powered by a motor that provides smooth rotation even at low speeds. The hub is coupled to a down rod and the motor may be detachably attached to the down rod. A counterweight may be a battery or a battery station that enables detachable attachment of a battery thereto. An illumination light is coupled to the hub to provide uniform light over the imaging area. A focal element and/or a centering light emitter may be configured along the rotational axis for aid in placing an object to be imaged.
