A bicycle helmet that fits over a surface of a head of a user generally includes at least one segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the at least one segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the at least one segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user.

A decorative band system to be worn around a limb of a user includes, for example, an elongated band, a first connector, and a second connector. The elongated band includes an inner surface disposable towards the limb of the user, and an outer surface facing away. The first connector is attached to the elongated band between the first longitudinal edge and the second longitudinal edge, and releasably attachable to one or more interchangeable decorative ornamentation. The second connector is attached to the elongated band and releasably connectable to a card so that the card is spaced apart from the elongated band. The elongated band and the second connector are configured so that when the system is worn on the limb of the user and connected to the card, the card is maintainable in a fixed relationship alongside and parallel to the limb of the user.

An attachment for mounting on straps extending between a rear opening of a cap. The attachment comprises a first panel having an outer and inner surface, and a clip section comprising a connector and a second panel having an outer and inner surface. The panels are spaced such that the first and second panels face each other and are substantially parallel to each other. The connector connects the first panel and the second panel at the top edge of the first panel and defines a gap between the panels. The gap is sufficient to permit the strap or straps to nest within, such that when the strap or straps are nested, the first and second panels lie on opposite sides of the strap or straps. The first and second panels contain ridges along their edges that engage the strap or straps and keep the cap attachment in place. The outer surfaces of the panels display advertising indicia or decoration and have a cushioned area.

The user wearable devices are configured to allow attendees of events to exchange their information upon a simultaneous input into their respective device. The simultaneous inputs initiate a verification that the two users are registered for and present at the same event before initiating a pairing through single direction short range antennas. The simultaneous inputs can also verify whether the two users are facing one another and an appropriate distance apart to coordinate the simultaneous input.

A system and apparatus configured to facilitate artistic expression across a variety of wearable and stationary mediums is described. The system employs framing elements which are disposed within a portion of a variety of wearable items such as T-shirts, backpacks, dresses, jean jackets, and others, as well as stationary items such as wall frames and standalone frames. The framing elements are equipped with retaining members which are configured to comfortably retain at least one design element in the desired location. Design elements can easily be removed and swapped out, or may simply be displayed elsewhere. Design elements may be made of a variety of eco-friendly materials, and the articles themselves are preferably consciously made for the benefit of the environment. The system serves to replace countless T-shirts with the capacity to change the appearance of a shirt or other article easily at will.

A hand-held, portable frame to support signs for street side promotions. This rugged, lightweight frame is made from aluminum or plastics and consists of various joints interconnected by square shaped insert tubes into a figure 8 configuration with optional extensions. To fasten, thumb screws attached to the joints that when twisted, pinch the insert tubes. The bottom brace member is a foot support. The middle brace member forms a hand support and is used as a body rest by leaning on it. Signs are attached only at the top allowing them to swing with the wind; minimizes user fatigue. Double sided signs can be used for viewing from opposite directions. All tubes come in multiple lengths and can couple together to form larger members. This frame stretches horizontally, vertically and in width providing numerous configurations. Recommended range is 2 to 6 feet horizontally and 8 to 12 feet vertically.
