A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

A security apparatus for a portable electronic device comprises at least one support member comprising opposing side surfaces and a plurality of support member surface features. At least one of the opposing side surfaces comprises a first engagement structure. One of the at least two arms comprises a second engagement structure configured to slidably engage the first engagement structure allowing movement in a first direction and opposing second direction. At least one locking assembly is positioned on at least one of the at least two arms and comprises a plurality of lock surface features configured to couple to the plurality of support member surface features. In a locked position, the at least one of the at least two arms is enabled to slide in the first direction. In an unlocked position, the at least one of the at least two arms is enabled to slide in the second direction.

A security apparatus for securing a portable electronic device comprises a support and a guide positioned within the support and defining a plurality of surface features. At least two holders are partially positioned between the guide and the support and define a plurality of complimentary surface features. A lock assembly is configured move between an unlocked state and a locked state. In an unlocked state, the at least two holders are enabled to move in a first direction that is away from the support and in an opposing second direction to move the at least two holders towards the support. In a locked state, the lock assembly moves the guide to clamp the at least two holders between the guide and the support to engage the surface features of the guide with those of the holders and inhibit movement of the at least two holders in the first direction.

A handle configured to be mounted on a pole (e.g., of an IV stand). The handle includes a handle grip having first and second ends with a central section therebetween. The central section is lower than the first and second ends. The handle grip is configured to be gripped by a user at a location between the central section and one of the first and second ends. The handle grip may include first and second sections that each extend upwardly from a central section. The first section is configured to be gripped at a natural grip angle by the user's a right hand and the second section is configured to be gripped at the natural grip angle by the user's a left hand. The handle may include a connector portion configured to be mounted to the pole and connected to the handle grip.

Display panel frames configured and dimensioned to support display panels and also attach to adjacent display panel frames in a modular fashion to form a larger display assembly. In some examples, the display panel frames include one or more structural members configured to support a load on the frame, wherein the structural members also have at least one display panel mount for attaching a display panel to the frame. In some examples, the frames are configured to support display panels having mounting interface points conforming with a Video Electronics Standards Association (VESA) interface standard.

An apparatus for physically securing a tablet and a keyboard to a tabletop of a display table or to another display surface is described herein. The apparatus includes a main body, a left arm and a right arm that are extendable and retractable relative to the main body and a left side brace and a right side brace attached respectively to the left arm and the right arm, and configured to be secured to a left side and a right side, respectively, of the tablet and the keyboard. The apparatus further includes a back support extending from the top of the main body with a top arm extending from the back support. The top arm is extendable and retractable relative to the back support along a plane that intersects the top of the main body at an oblique angle.

A gas cylinder quick release device has a cylindrical upper assembly, a cylindrical lower assembly arranged below the upper assembly on a common axis, and a handle which is mounted to move between a first position and a second position. Movement of the handle from the first position to the second position imparts axial displacement of the upper and lower assemblies away from each other along the axis, thereby breaking a press-fit engagement of a wheelbase otherwise secured on the gas cylinder.

A suspension system for a speaker line array is provided with a base to mount to a first speaker cabinet. A rail extends transversely from the base. A bar is mounted relative to the rail between a stowed position and an extended position, wherein the bar is biased away from a central portion of the base to the extended position to contact another speaker or a support. A locking mechanism is driven by a transmission to lock the bar in the stowed position.

The quick mounting structure includes a first connector, a second connector, and a self-locking mechanism; the self-locking mechanism is on the second connector, and the first connector is connected to the second connector through the self-locking mechanism; the self-locking mechanism includes a quick mounting block, a transmission arm, a locking block, a rotating shaft, and a first elastic member; the quick mounting block is connected to the first connector; the second connector is provided with a quick mounting groove, and all of the transmission arm, the locking block, the rotating shaft, and the first elastic member are arranged in the quick mounting groove; the transmission arm is rotationally connected to the second connector through the rotating shaft; the first elastic member is connected to the transmission arm or the locking block for enabling the locking block to be in a locked state in a normal state.

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.
