Powerisers are jumping stilts produced by the Poweriser company of Korea. They were originally patented by Alexander Bock (US Patent No. 6,719,671 B1) on April 13, 2004.

Each boot consists of a foot pad with snowboard type bindings, a pivoting foot and a fibreglass leaf spring, giving the wearer the potential to jump 1–1.5 metres (3–5 ft) off the ground and 10 foot strides.

Ribcap - New head protection for all outdoor activities. Ribcap is a woollen cap with sewn-in d3o impact responsive protectors. It offers you all the advantages of a normal hat, cap or beanie and can at the same time protect you against bumps, bruises, grazes and light concussion.

Using d3o (dee-three-oh) technology Ribcaps are unique. This flexible material hardens on impact instantaneously and immediately returns to its former soft state. d3o is capable if absorbing the impact within fractions of a second and can therefore protect your head against injuries like bumps, bruises, grazes and light concussion. The protection-effect is also guaranteed for low temperatures downto -30° C and for extreme dampness.

IMPORTANT: Please note that although Ribcap with d3o technology offers much greater protection than a regular cap, Ribcap does not offer complete head protection nor comply with any standards established for protective headgear like helmets.
