The invention discloses a traceable card holder, comprising a first clamp plate, a second clamp plate, an elastic band, top cover components, bottom cover components, a tracker and an elastic clamp; the first clamp plate is arranged oppositely to the second clamp plate, the elastic band is connected respectively with the first clamp plate and the second clamp plate, and the elastic band is used to drive the first clamp plate and the second clamp plate to move towards each other for clamping; the top cover components are detachably mounted on one side of the first clamp plate which is away from the second clamp plate, and the tracker is detachably mounted on the top cover components.

A wirelessly locatable tag may be configured to transmit a wireless signal to an electronic device to facilitate localization of the wirelessly locatable tag by the electronic device. The wirelessly locatable tag may include an antenna assembly comprising an antenna frame defining a top surface and a peripheral side surface and an antenna positioned along the peripheral side surface and configured to transmit the wireless signal. The wirelessly locatable tag may further include a frame member coupled to the antenna assembly and defining a battery cavity configured to receive a button cell battery and an enclosure enclosing the antenna assembly and the frame member. The enclosure may include a first housing member formed from a unitary polymer structure and defining a top wall defining an entirety of a top exterior surface of the wirelessly locatable tag.

A wallet assembly that receives a contactless payment card includes a wallet arranged as at least a bifold wallet with first and second wallet sides, one side configured to receive the contactless card and the other configured to receive additional items and payment cards. RFID shielding eliminates electromagnetic signals from the additional payment cards. A flap attached to the wallet side holding the contactless card has a hole or window that physically exposes a portion of the payment card.

An activity classifier system and method that classifies 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. The system 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. The system also has 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 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.

A mechanical wallet or cardholder can be opened using one hand by sliding a top or second plate along rails parallel to a bottom or first plate. A card arm forces cards in the cardholder (i.e., located between the first and second plates) out a second end of the cardholder in a fanned or stepped fashion. A magnet in the card arm and in a first end of the frame (opposite the second end of the cardholder and frame) cooperate to return and retain the card arm and first plate in the closed position. A card lock at the second end of the frame retains cards in the cardholder when the cardholder is in the closed position and allows the cards to be pushed from the second end of the cardholder by the card arm when the second plate is moved to the open position.

An accessory for a mobile electronic device includes a platform, a wallet, and a grip accessory coupled to the wallet. The platform is adapted to be attached to the mobile electronic device or a case for the mobile electronic device. The wallet is attached to the platform and configured to hold one or more objects associated with a user of the accessory. The grip accessory is adapted to permit a user of the accessory to securely grip the accessory and includes a base and a gripping element movable relative to the base.

An accessory assembly for a mobile electronic device includes a platform, having a first side and an opposing second side. The platform includes one or more magnetic elements configured to magnetically attach the platform to a mobile electronic device or case along the first side. The accessory assembly also includes a wallet integrated with or attached to the second side of the platform, where the wallet is configured to hold one or more objects associated with a user of the accessory. The assembly also includes a grip accessory configured to attach to the wallet, where the grip accessory is configured to be handheld in order to support the accessory assembly and mobile electronic device when magnetically attached to the platform.

A wallet is provided having a body adapted to hold credit cards, currency, and business cards. The credit cards are insertable to a biased engagement in a first compartment between two flexible members. A second compartment is positioned below the first compartment and configured to hold currency therein in biased contact between a biasing panel and a credit card in the first compartment. A third compartment is provided and configured to hold business cards.
