A device that causes a weapon to fire upon a target when the weapon is enabled by an operator, and when the weapon point of impact passes through a target or in a proximity thereto and when the target satisfies certain criteria as determined by one or more sensors/designations. This invention represents a significant paradigm shift. Some prior art (large scale) weapons automatically acquire/track/prioritize/target/fire upon targets without operator intervention (i.e. Phalanx). Most prior art weapons, especially but not limited to small arms, are manually aimed, and fire immediately upon an input (trigger pull, or equivalent) from the operator. The current invention is a novel approach which triggers the release of a round, multi-round burst, rocket, missile, or other projectile(s) when enabled by the operator, and when the target passes through the point of impact (or desired/computed proximity thereto), relieving the operator of the split second judgment in timing the release and/or cessation of such fire. The results intended include a reduction in off-target rounds fired, increased hit rate, conservation of ammunition, more effective targeting for non-motion-stabilized weapons (in particular small/medium arms), and the introduction of a backup mode for nominally motion-stabilized weapons which may allow effective operations when primary stabilization systems fail or are overwhelmed by dynamics. This invention is applicable (in embodiments of varying complexity) to weapons ranging from handheld pistols to the main (artillery) gun of a tank, a ship, or the cannon aboard an aircraft.

A position of a surgical tool in the 3D spatial map is detected and a determination is made by the system indicative of whether the needle protrusion distance is sufficient for grasping by the surgical tool. A warning is generated when it is determined that the needle protrusion distance is not sufficient for grasping by the surgical tool.

A brewing module for preparing a brewed drink from a portion capsule, includes a first brewing module part and a second brewing module part, which is movable relative to a housing between a first brewing module part position and a second brewing module part position. An operating element is able to be brought manually from a first into a second operating element position, from which a movement is transmitted via a transmission mechanism into a movement of the second brewing module part. The transmission mechanism includes a cam disc that is rotatably mounted on the housing by the operating element wherein the second brewing module part is displaceable along a displacement stretch, which is fixed with respect to the housing, from a first brewing module part position into the second brewing module part position by way of the cam disc being rotated by the operating element.

A foldable garment hanger is disclosed which includes a hook which can be folded relative to the garment supporting portion by virtue of a hinge. A size marker is attached to a connecting portion which joins the hook to the garment support portion and includes the hinge. When the size marker straddles the hinge the connecting portion is held rigid thereby fixing the hook relative to the garment support portion. Preferably the size marker is slidable to expose the hinge thereby allowing the hanger to be easily moved between an erect display condition and a folded transportation condition.

The present disclosure relates to the technical field of tea brewing devices, and more particularly, to a beverage brewing device. The beverage brewing device comprises a kettle body, a heating disc, and a tea-leaf basket. The heating disc and the tea-leaf basket are located in the kettle body and an air cylinder mechanism is fixed in the kettle body. A moving piston is arranged in an inner cavity of the air cylinder mechanism, and the piston is connected to the tea-leaf basket. The air cylinder mechanism is connected to an air pump, which is used for conveying a driving gas to the air cylinder mechanism. The piston is driven by the driving gas, thereby driving the tea-leaf basket to move in the kettle body. The air cylinder mechanism may automatically drive the tea-leaf basket to move up and down, achieving a simple structure and a low cost.

A system and method for rotating an ornament, so that the ornament can be easily decorated. The decorating device has a housing that defines an interior compartment. Within the interior compartment, a mount receives and engages the neck of the ornament, therein temporarily connecting the ornament neck to the mount. The ornament is passed into the housing through an access opening in the housing. When connected to the mount in the housing, at least some of the ornament extends out of the housing through the access opening. A motor is used to rotate the mount and ornament. As the ornament rotates, the section of the ornament that extends out of the access opening can be contacted with marking devices. In this manner, the ornament can be decorated as it spins.
