A night vision goggle adapter including: a goggle mount assembly; a primary magnet generating a magnetic flux; a magnetic flux conducting unit having a first end and a second end; a first plurality of shunts; and a second plurality of shunts disposed about the goggle mount assembly; wherein the magnetic flux conducting unit may overlap the primary magnet and form a magnetic circuit for conducting the magnetic flux towards the second end of the magnetic flux conducting unit when none of the first plurality of shunts and none of the second plurality of shunts are overlapped by the magnetic flux conducting unit; and wherein the magnetic flux is shorted through one of the first plurality of shunts or the second plurality of shunts when the magnetic flux conducting unit is positioned to overlap one of the first plurality of shunts or one of the second plurality of shunts.

A lift system including a bracket configured to support an object, a support having a first end and a second end, the first end being movably engaged to the bracket, at least one cam engaged to the second end of the support, and a base including a cam follower configured to engage the at least one cam, and at least one bias element having a first end and a second end, the first end engaged to the cam follower.

A short throw projector mount enabling a finely tuned distance adjustment and/or finely tuned height adjustment of an attached projector. The mount includes a wall interface, a projector positioning head, and an elongate arm operably coupling the wall interface and the projector positioning head. A first end of the arm is coupled to the wall interface, and the projector positioning head is operably coupled proximate an opposing second end of the arm such that the projector positioning head is shiftable along a longitudinal axis of the arm. The arm further includes a positioning mechanism arranged to selectively drive shifting of the projector positioning head. A vertical positioning mechanism may be provided to shift the projector vertically relative to the wall interface.

A detection apparatus includes four sets of transmitter and receiver wherein the transmitters are on a first sliding member of a frame and the receivers are on a second sliding member of the frame; and drives for moving the first and second sliding members back and forth. During the movements of the first and second sliding members, each transmitter emits laser beam toward the receiver of the same set by passing through a space above a photoresist-coated optical glass by 100 μm, no signal is generated at the receiver if the laser beam is not blocked, and a signal is generated at the receiver if the laser beam is blocked by at least one of a plurality of particles on the photoresist-coated optical glass.

The invention includes a payload stage with tilt head, a monitor mount and a payload plate clamping mechanism, individually, and incorporated into a camera stabilizer. The tilt head provides a curved and a straight slot each having a pivot pin disposed therein. The pivot pins are at a fixed distance from one another and thus the stage tilts as the pivot progresses with respect to the straight slot. The monitor mount provides inserts to accommodate central posts of different sizes, each designed to be axially registered to the posts and the monitor mount.

Device (1) for showing a marking (A) in the form of a distance to be observed between a game apparatus (15), in particular a football, and participants on a playing field (22) of a sports facility (2), having a display device (3) for projecting light beams (L) representing the marking (A) onto the playing field (22), wherein the projected light beams (L) display the distance to be observed and can be projected in the shape of a circle, at least in sections, in particular at a distance of 9.15 m around the game apparatus (15) on the playing field (22), wherein the display device (3) is jointly movable with a transport device (8) that is movable above the sports facility (2).

The adjustable display track system comprises a track and a roller car. The adjustable display track system may be adapted to move a flat screen display that is coupled to the roller car along the track between a lowered position and a raised position. The adjustable display track system may be adapted to lower an elevation angle of the flat screen display as the roller car is raised such that the flat screen display continues to point towards a user. Motion of the roller car may be controlled remotely from a smart device.

A mounting system for securing an electronic device to a rifle, the mounting system includes a base member and a slider member. The slider member includes a plurality of bumper members extending therefrom, the slider member secured to the base member and movable between an extended position, to enable the electronic device to be inserted between at least a pair of bumper members, and a retracted position, to enable the bumper members to abut against and secure the electronic device to the mounting system.

A lens bracket assembly for supporting an imaging device. The imaging device includes a body and a lens connected to the body. The lens bracket assembly includes a mounting plate, a supporting plate configured for carrying the imaging device, and a bracket. The mounting plate includes a first surface and two inner sidewalls extended from two opposing ends of the first surface along a direction substantially perpendicular to the first surface. The two inner sidewalls provide first sliding slots. The supporting plate includes a first side and two outer sidewalls providing second sliding slots, and is slidably disposed on the mounting plate with the second sliding slots matching the first sliding slots at corresponding positions. The bracket is coupled to the first side of the supporting plate, and includes a shape that matches the lens of the imaging device.

An arm-type support device includes a first frame, a second frame, a first arm member, a second arm member, and an actuator. The actuator includes a driving unit, an actuating rod, and a link member. The first arm member, the second arm member, the first frame, and the second frame form a parallel link. The first arm member is hollow and accommodates the actuator and the second arm member.
