Abstract: A jump safety system and method for monitoring a jump landing area is described. The system of examining a landing area associated with the jump includes a camera, a memory, a processor, an image processing module, and a light emitting output. The camera is positioned to generate a camera output that displays the landing area. The landing area has a declining slope angle that reduces a landing force in relation to the slope angle.

Abstract: A system is provided for automatically activating a boot-mountable highback between a walk mode and a ride position. In the walk mode, the highback is unrestrained, permitting the boot to flex freely, and consequently allowing the rider to walk comfortably. In the ride position, the highback is tilted toward the toe portion of a boot and prevented from movement in the heel direction beyond a preselected forward lean position, so that leg movement in the heel direction is transmitted through the highback into a gliding board. The highback is adjusted between the walk mode and the ride position simply by stepping into or out of a binding attached to a snowboard. Activation and deactivation of the highback may be achieved through direct or indirect interaction with a board-mounted actuator that may be attached to the binding. A forward lean adjuster may be provided that allows a rider to preselect the amount of forward lean attained when the highback is activated into the ride position.
