Rapid access storage devices and systems are provided herein, which allow a user to quickly retrieve items stored behind, to the side of, or otherwise out of a comfortable reach range of the user. The devices comprise a housing, and at least one carriage retractable from the housing via a retraction assembly. Rapid access storage systems may comprise a wearable item, including hanging items, that include or are coupled to one or more rapid access storage devices.

A system of maintaining the form of a pocket square comprises an insert, a pocket square sleeve, and a holder. The insert comprises a semi-rigid or rigid material. The pocket square sleeve comprises fabric sewn along a lengthwise seam to form a sleeve and a second seam substantially perpendicular to the lengthwise seam forming a cavity configured to receive the insert. The holder comprises an elongate member and a fastening element, the elongate member configured to be folded to cause engagement of the fastening element. The insert is disposed in the cavity of the pocket square sleeve and the combined insert and pocket square sleeve is disposed in the holder with the fastening element engaged.

An attachment system for a portable electronic device includes a clip unit including a clip magnet disposed between a base plate and a top cover and a clip lip formed on the top cover; and an attachment adapter for attached to a back side of the base plate and configured for attachment of the clip unit to an article. The clip magnet is positioned to be aligned with a magnet in the portable electronic device when mated with the portable electronic device. The attachment system enables the portable electronic device to be quickly and easily attached to a desired article and further enable quick release of the portable electronic device from the attachment system.

In the world of bear spray, options for holsters are almost nonexistent. Manufactures of bear sprays offer holsters that are designed to be inexpensive, and mass produced. Most of these holsters require the use of a belt, something a lot of people are not wearing while they are hiking, hunting, or camping. The current options available completely lack versatility to the users preferred attire and are of a disposable nature. I felt that if a product as wonderful as bear spray is to work to save humans and bears lives it must be able to be carried in a comfortable user-friendly holster that has different attachment options that will work with the attire that the user is going to be wearing. It needed to be in a holster that retains and protects the canister and allows for lightning fast draws in dangerous situations. I worked hard to create a holster that is high quality, durable, and aids to assist preform the task of quickly deploying bear spray in high stress, emergency situations. Holsters are as much of the protection system as the canister of bear spray itself.

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 folding knife with pocket clip has a knife frame, a flexible elongated resilient pocket clip having a first end connected to the knife frame and a second free end proximate the knife frame, the flexible elongated resilient pocket clip defining a plurality of louvers, each louver defining a slit transverse to the length of the flexible elongated resilient pocket clip and having an elevated edge, and each elevated edge facing toward the second free end. The louvers may be parallel to each other. The louvers may be at an intermediate location spaced apart from the first end and second free end. The knife frame may have a pivot end to which a blade is pivotally attached, and the elevated edges may face toward the pivot end.

A magazine retention device includes an attachment pouch and an insert. The attachment pouch includes a front panel, a rear panel opposing the front panel, and an attachment portion. The front panel is secured to the rear panel forming a cavity between the front panel and the rear panel. The attachment portion is configured to attach to a carrier. The insert is disposed within the cavity and secured to the attachment pouch. The insert has an first region and a second region. The first region includes a rectangular opening configured to receive a magazine. The second region includes one or more walls that bias toward a center of the cavity. Here, the one or more walls bias in contact with a received magazine.

A pocket clip for a tool includes a mounting section that defines a width between a first side opposed to a second side. A friction section is flexibly connected to the mounting section, and the friction section has a distal end biased toward the tool when the mounting section is attached to the tool. An aperture is through the friction section. A first slot extends from the first side of the mounting section partially across the width of the mounting section, and at least a portion of the aperture through the friction section is aligned in line with the first slot. A first connector in the first slot of the mounting section attaches the mounting section to the tool.

First-aid systems comprising an ultra compact first-aid pouch configured to fit behind the ballistic plates of a protective vest are disclosed. In this configuration, the first-aid kit is protected from shrapnel and tearing, is easily locatable and removable and does not effect the user's freedom of movement. When the first-aid pouch is removed from its protected location, it presents the first-aid equipment in a logical and easily viewable manner.
