An RFID protection and low frequency signal isolation sheet for a folding wallet has a metal interlayer. Upper surface and the lower surface of the metal interlayer are covered with protective layers to form an RFID protection folding sheet. The RFID protection folding sheet is inserted into a cash compartment of a folding wallet. The RFID protection folding sheet has a length slightly less than that of the cash compartment. The RFID protection folding sheet has a width slightly less than a depth of the cash compartment. The RFID protection folding sheet is placed into the cash compartment and located at an inner edge close to an outer layer of the folding wallet. By folding the folding wallet, the RFID protection folding sheet forms the peripheral protection of the folding wallet, and the data of the electronic chips (RFID) of cards inside the folding wallet is blocked.

The disclosure includes a wallet comprising an open-sided shell, a flexible member coupled to the open-sided shell, and a pull tab coupled to the external surface of the flexible member. The disclosure also includes a wallet comprising an open-sided shell, a flexible member coupled to the open-sided shell, a stretchable band configured to wrap around the open-sided shell and the flexible member, and a radio frequency identification (RFID) protection plate coupled to the open-sided shell. In some embodiments, the RFID protection plate is configured to securably couple at least one personal card between the RFID protection plate and the open-sided shell. The disclosure includes a wallet comprising an open-sided shell, a first protruding portion coupled to the open-sided shell, and a second protruding portion coupled to the open-sided shell.

A contactless card divider includes a body having a front side and back side and a width therebetween, and a waveguide disposed between the front and back sides. The waveguide is configured to guide a first electromagnetic wave emitted toward the front side through the width of the body to the back side with a first predetermined delay.

The purse with concealable compartments is an apparatus that houses a variety of items. A first compartment and a second compartment are defined as the apparatus includes an outer layer, a folding edge, at least one flap, at least one elongated fastener, and a plurality of fasteners. The first compartment houses a variety of items such as money, cards, and so on, which are readily viewable. The second compartment houses preferably concealed items such as feminine products. The folding edge laterally traverses across the outer layer such that the outer layer surrounds the variety of items. The at least one flap is hingedly connected with the outer layer thereby concealing the preferably concealed items with the plurality of fasteners. The at least one elongated fastener secures the items within the apparatus as the at least one elongated fastener is perimetrically connected across an inner surface of the outer layer.

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 anti-theft pocket insert designed to prevent a pickpocket from stealing items stored within a traditional pocket. The anti-theft pocket insert includes a first fabric member having a front surface and a rear surface. A second fabric member is affixed to the front surface of the first fabric member such that a compartment having an interior volume designed to hold a passport or wallet is formed. An upper side of the second fabric member is not affixed to the first fabric member such that an opening in communication with the interior volume is formed. Further, the first fabric member is greater in length than the second fabric member such that a top edge of the first fabric member overhangs the opening. In this way, a user is able to store items inside the anti-theft pocket insert and place the insert within a pocket to prevent pickpockets from stealing the items.

System and method of storing cards for ease of carrying and access by a user. The system, which may be a wallet, may include a sleeve or band that tightly holds or maintains a card or plurality of cards. The sleeve may have an opening at the top and at the bottom to allow for cards to be positioned within the sleeve. A pull-strap may be coupled to the sleeve and weave through the sleeve in an S-shape to create a first pocket for cards and a second pocket for cards. The pull-strap may pass through a guide in the body of the sleeve that can be pulled or actuated to allow for easy retrieval of the cards from the pockets. The pull-strap and cards can be easily retracted within the sleeve with a single hand of a user.
