This disclosure is directed to an activity classifier system, for classifying human activities using 2D skeleton data. The system includes a skeleton preprocessor that transforms the 2D skeleton data into transformed skeleton data, the transformed skeleton data comprising scaled, relative joint positions and relative joint velocities. It also includes a gesture classifier comprising a first recurrent neural network that receives the transformed skeleton data, and is trained to identify the most probable of a plurality of gestures. There is also an action classifier comprising a second recurrent neural network that receives information from the first recurrent neural networks and is trained to identify the most probable of a plurality of actions.

An illustrated view of an exemplary jewelry concealment apparatus for concealing jewelry and preventing potential theft is presented. The jewelry concealment apparatus is useful for a diversion to thieves searching for jewelry to steal when invading a home, office, etc. Also, the jewelry concealment apparatus is useful providing an enhancement to a room or other area. The apparatus has a vessel, a lid and a flower arrangement. The vessel is void in the interior and is preferably a vase. The lid is substantially flat. One or more coupling devices are coupled to a bottom of the platform when the bottom is coupled to a top edge of a top of the vessel. The one or more couplings may be the same or different and are preferably hooks. Items such as jewelry are removably coupled to the couplings. A bottom of the flower arrangement is removably coupled to a top of the platform. A top of the flower arrangement is a flowering group that is preferably artificial.

There is disclosed a compact wallet, comprising at least two rigid plates at least one having a channel into which an encircling elastic band is interposed to bias the at least two rigid plates inwardly and securely hold the card-like contents while providing elastic volume therebetween while allowing freedom for the dynamic extension and contraction of the band over the entire running length of the wallet. The wallet includes an auxiliary feature removably attached within the interior at least one of the at least two rigid plates interposed using a tang inserted into a recess formed inside the plate, the tang having a hook, the hook extending at an angle to the tang, the hook engaging an undercut of the recess to prevent inadvertent dislodgement of the auxiliary feature from the recess.

The invention relates to a system of self-adjusting straps that allow the weight or load contained in the element-holding object, such as a briefcase, backpack or suitcase, to be distributed evenly and automatically over the user's two shoulders, ensuring that the object is perfectly balanced and that it fits ergonomically on the user's back. The invention also to a rear protection mechanism with a magnetic opening system, intended for objects used to hold elements, such as, for example, briefcases, backpacks or suitcases. The mechanism acts an anti-theft system for rear, side and/or lower pockets on said objects. The rear mechanism with a magnetic opening system comprises flaps with non-visible magnets located inside said flaps, which, upon coming into contact with other magnets located on the rear surface of the object, generates an attraction that secures the flaps.

A bag with anti-cut and bullet-proof functions is mainly configured with a protection assembly on a bag body including a main body opened with an opening, a protection layer configured on the main body and an active layer accepted inside the main body, where the protection layer and active layer are made of reinforced fabric. Meanwhile, the bag body is configured with a sealing element adapted to control the opening and closing of the opening so that a user only needs to open the sealing element when encountering danger, allowing the active layer to slip out through the opening to cause the active layer and protection layer to form a large anti-cut and bullet-proof area so as to resist bullet impact and block the cutting of sharp weapons, and further substantially increase the overall protection area to achieve the effect of maintaining the personal safety of users.

Disclosed are a method for unlocking a fingerprint recognition lock and a zipper lock with fingerprint recognition. The fingerprint recognition lock includes a lock box and a movable locking plate detachably stacked on and locked by the lock box, and the movable locking plate has a fingerprint collection module or a fingerprint reader, and the lock box at a locked status maintains a power disconnection status. Only if a user presses the movable locking plate, the lock box will perform fingerprint collection or fingerprint recognition after power is supplied to the movable locking plate through a terminal supplying power. This disclosure has the effects of saving power and reducing the volume of the fingerprint recognition lock.

The present invention is in the field of a flexible tamperproof suitcase locker, which is made of a flexible foil, a method of applying said suitcase locker, and various further applications thereof. Typically the present suitcase locker is of a one size fits all dimension, hence applicable to each and every suitcase. Further the foil typically has a clearly recognizable and differentiating print or the like.
