A money and card carrier assembly includes a first component having a first portion, wherein the first portion includes a plurality of pockets formed therein. Each of the plurality of pockets is sized to allow a credit card to be releasably retained therein. The assembly also includes a second portion, with a first hinge connecting the first portion and the second portion. A second component has a sleeve sized to allow the second portion of the first component to be removably inserted therein and a plurality of pockets located on either side of the sleeve. Each of the plurality of pockets is sized to allow a credit card to be releasably retained therein. A third component has a first generally planar portion, a second generally planar portion, and a second hinge connecting the first generally planar portion to the second generally planar portion. Each of the first and second generally planar portions is sized to be removably insertable into the sleeve.

A hardware wallet and a hardware wallet holder identity verification method, relating to the field of digital currency. The hardware wallet comprises a virtual machine, a biological characteristic authentication module, and multiple wallet applications. Each wallet application stores a private key. The hardware wallet records, for each wallet application, a biological characteristic for verifying hardware wallet holder identity corresponding to each wallet application by using the virtual machine and the biological characteristic authentication module. Private key pair digital currency in the current wallet application can be used for trading only when verification of the hardware wallet holder identity corresponding to the current wallet application succeeds. The digital currency security protection mechanism is improved, and identity authentication management of multiple wallet applications is realized.

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.

A small-volume and foldable charging card holder includes a power source and a wallet. The wallet is provided with at least one card slot for receiving cards. The wallet is provided with a bendable portion, and is connected to the power source through the bendable portion such that the wallet is capable of being folded towards the power source or unfolded. The power source and the wallet are designed in a left-right structure that can be relatively folded.
