A device comprises a first tube having a first diameter and a second tube having a second diameter. A spring may be disposed between the first tube and the second tube. The spring may couple the first to the second tube. A plurality of tines may be disposed at a first end of the first tube and at a first end of the second tube.

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.

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 present invention relates to a smart wallet that is comprised of a plurality of security features such as a voice-activated magnetic lock and a bio-metric fingerprint, wherein each lock may be programmed via a mobile application. The smart wallet is further comprised of a camera that allows a user to view the surroundings of the wallet if lost or a criminal who may have stolen the wallet, and an internal battery that may power the camera and lock and may also serve as a personal and portable power bank that allows a user to charge their personal belongings via a plurality of USB-Ports. The smart wallet also includes an RFID shield, and a user may create virtual versions of any card type within the wallet, wherein the user may then pair the mobile application with the wallet to use the app to pay for goods/services.

A cut resistant and highly translucent tote utilizes a multilayer knitted metal fabric having a knitted metal outside layer and a knitted metal inside layer. These two knitted layers may be independent in a portion of the tote, such as in a clear-view portion of the tote, configured to allow clear visibility of items retained in the tote. The independent layers of knitted fabric are highly cut resistant, as they can flex in multiple direction and also move and slide with respect to each other. The tote may have a gusseted base with a base-side sleeve extending at the intersection of the base and sides to allow the tote to be free standing. An opening in the top of the tote may have a closure feature, such as hook-and-loop fastener material.

The present invention is a compact wallet designed to present a minimal silhouette in a shirt, pants or purse pocket. Novel features hold the silhouette to the minimal dimensions of a credit card while affording maximal expandability for content storage and accessibility. A novel method makes additional features modularly available.

A wallet assembly wherein a biometric credit card and enrollment key are positioned in the wallet to enable transfer of electric power.

In various embodiments, a carry (or carrying) bag is provided that includes an interior, substantially cut-resistant security panel assembly with a matrix of wires secured between or on one or more flexible material layers. Also in various embodiments, the security panel assembly may be positioned intermediate the bag outside wall and a lining of the bag, and in other embodiments, may also take the form of an expansion panel. Second or secondary locking fasteners are also provided to lock first or primary fasteners to or within the carrying bag, to provide security for compartments and pockets. A strap with one or more security cables, and various locking fasteners, may be attached to the carry bag. Methods for forming such security panel assemblies, expansion panels, and carrying straps are also disclosed.

An accessory for a mobile electronic device includes a platform and a wallet. The platform is adapted to be attached to the mobile electronic device or a case for the mobile electronic device. The wallet is removably attached to the platform and configured to hold one or more objects associated with a user of the accessory.

A wallet having first and second locking fixtures, the wallet configured to secure money, credit cards and identification with the added advantage in some embodiments that the contents are viewable within the wallet even when the first and second locking fixtures are securely closed.
