Abstract: A helmet includes an energy absorbing layer and an outer shell mounted to the energy absorbing layer. The outer shell includes an air trip in the form of a continuous groove that extends from a bottom left side of the helmet to a bottom right side of the helmet.

Abstract: A bicycle frame has a plurality of frame members that includes a first member and a second member, the first member having an outer sheath disposed at one end, wherein the outer sheath at least partially surrounds the second member with a gap therebetween such that the outer sheath does not directly touch the second member. An elastically deformable coupling is disposed in compression between the outer sheath and the second member, the elastically deformable coupling being disposed to at least partially fill the gap.

Abstract: A utility vacuum that may be configured to employ a disposable bag or removable and reusable container for the collection of dirt and debris that are drawn into the utility vacuum. The utility vacuum may employ one or more movable legs that are movable between an extended position, which provides relatively stable operation of the utility vacuum, and a retracted position, which reduces the footprint of the utility vacuum so that it is easier to store.

Abstract: A vacuum that includes a container, a hose in fluid communication with the container, a fan assembly coupled to the container, an attachment and an accessory apron. The fan assembly includes a fan housing and a fan that is configured to draw a debris-laden air flow through the hose and into the container. The attachment is capable of being releasably coupled to at least one of the hose and the fan housing. The accessory apron has a strap and a holder that is sized to receive and removably store the attachment. The strap is configured to be releasably secured to at least one of the canister and the fan assembly.
