Abstract: A detachable pedal assembly including an axle assembly and a binding assembly with an automatic release mechanism is disclosed. The axle assembly includes a thrust bearing and threads to engage the crank. The binding assembly includes a pedal and clasp that detachably receives and locks the thrust bearing of the axle assembly in operational engagement. When a predetermined force is applied the binding assembly automatically releases from the axle assembly to permit the cyclist to dismount or avoid injury in an accident. Furthermore, the position of the release mechanism to the side of the binding assembly permits the binding assembly to be offset from the axle axis, thereby improving increased riding efficiency, lower aerodynamic drag, and increased turning clearance.

Abstract: A multiple-dose syringe including a barrel with a closed end and an open end, the closed end having an injection port adapted to receive a needle. A plunger is slidably disposed through the open end of the barrel. A container is connected to an end of the plunger to move with the plunger. The container has a deformable shell with an opening at a forward end thereof and a predetermined quantity of fluid sealed therein by a closure member disposed over the opening. The container is slidably disposed in the barrel and includes a seal proximal to the forward end to form a first cavity in the barrel with a volume that is adjustable by moving the container in the barrel with the plunger so that fluid can be selectively drawn into and expelled from the first cavity. After at least a substantial portion of the fluid is expelled from the first cavity, the shell is configured to be collapsed by further pressure applied by the plunger to expel the predetermined quantity of fluid contained therein.

Abstract: A pneumatic isolator for isolating payloads from vibrations consisting of a vertical isolator suspended from pendulum wires. A second downward-facing piston prevents changes in barometric pressure from generating disturbing forces on the isolated payload.
