Embodiments of a strap assembly system for a golf bag are described herein. The strap assembly system can be converted between a single-strap configuration or a double-strap configuration. The strap assembly system comprises a first strap, a second strap, and a back puck. The back puck comprises first and second attachment openings for securing the first strap. The back puck further comprises first and second side openings that define a linear pathway and are configured to receive the second strap. The second strap can move freely along the linear pathway.

The present disclosure is directed to carrier device, and related systems. A device may include a handle and at least one attachment device coupled to the handle. The at least one attachment device may be configured to couple to a solar module, wherein each attachment device includes at least one of a channel for receiving a portion of a frame of the solar module.

A display, securing and transporting device can be used with many types of footwear, including boots, dress shoes, sandals, cleats, high heeled shoes and casual shoes. The device comprises a first elastic body adapted to retainingly and releasably engage a perimeter of a first one of a pair of footwear. The first elastic body defines a toe receiving portion and a heel receiving portion; and a lateral band connects the toe receiving portion and the heel receiving portion. A second elastic body is adapted to retaining and releasably engage a perimeter of a second one of a pair of footwear. The first elastic body and the second elastic body are coaligned and attached to one another at their respective lateral bands. A mounting means is provided on the device to receive a hanger.

A modular backpack system includes a personal floatation harness having an automatic inflator mechanism and pack attachment features; and a plurality of pack modules selectively attachable to the pack attachment features to form a floatation-enhanced backpack. Each one of the plurality of pack modules may further include a different arrangement for accommodating accessories. For example, the different arrangements may include arrangements having different compartments. Other arrangements may have different attachment features. The different attachment features may include different lash points. The backpack module may be one taken from the list of: a pack adapted for kayaking with a waterproof compartment and lash points for ready access to accessories; a pack adapted for sailing with waterproof and non-waterproof compartments; a pack adapted for hiking with multiple compartments for tools and supplies; and a pack adapted for everyday carry (EDC) having multiple quick-access compartments for carrying everyday tools.

A footwear carrying system may include first and second separate carriers, each having a first attachment point near a first end of the carrier, a second attachment point near a second end of the carrier opposite the first end, and a third attachment point along a side of the carrier. A first strap may be adapted to connect the first and second attachment points of the first carrier, and a second strap may be adapted to connect the first and second attachment points of the second carrier. The third attachment points of the first and second carriers may be adapted to connect the first and second carriers together. The carriers may be suspended from one or more shoulders of a wearer, or attached to another carrier using the straps or a connection between the first and second carriers.

A backpack kickstand assembly for supporting a backpack while the backpack is being worn includes a backpack frame that can be worn on a user's back. A backpack is removably mounted to the backpack frame to facilitate the backpack to be carried on the user's back. A kickstand is attachable to the backpack frame and the kickstand is positionable in an extended position to support the weight of the backpack frame while the backpack frame is being worn to facilitate the wearer of the backpack frame to rest. The kickstand is positionable in a retracted position to facilitate the wearer to bear the full weight of the backpack frame.

A multi-component, multi-functional carry bag having a first storage component and at least one additional storage component, which are detachably coupled. The carry bag can display selectively interchangeable display material thereon, and is operably able to be disassembled and reconstituted for another purpose, and then adapted back to its original bag form, if desired. The bag is further network and Internet accessible, to permit the user of the bag to selectively interchange display material on the bag through access to the Internet and/or network.

A backpack is provided which includes a sleeve housing a protector. The protector includes a top handle section, a middle padded section, and a bottom section. The middle padded section act as a protective layer between a cloth worn by a user and a seating surface. The backpack enables avoiding contamination of the clothing of the user, thereby reducing healthcare-associated infection. The invention also provides a wearable guard. The wearable guard includes a sleeve. The wearable guard is adapted to worn as a backpack or a sack thorough the sleeve, making the wearable guard comfortable to place on shoulder of the user. The wearable guard also includes a protector housed inside the sleeve. The wearable guard enables protection of the cloth worn by the user from unsanitized seats, especially encountered when taking public transportation.

The disclosure belongs to the technical field of powered drive devices, and discloses an acceleration control method for a load on a powered backpack based on a disturbance observer. The method includes: S1 setting the desired acceleration of the load on the powered backpack, presetting the initial motor drive current that regulates the movement of the load according to the desired acceleration, measuring the actual acceleration of the load; S2 establishing the disturbance observer for controlling acceleration the load on the powered backpack, using the disturbance observer to calculate the motor drive current that makes the actual acceleration of the load equal to the desired acceleration, so as to realize the acceleration control of the load on the powered backpack.
