Abstract: A walker stabilizing platform including a movement restrictor assembly for assisting a user of a walker in transitioning from a sitting position to a standing position wherein the movement restrictor assembly automatically moves from a position of engagement with the walker to a position of disengagement with the walker, and further includes means for allowing the user of the walker to move the movement restrictor assembly from the disengaged position to the engaged position without assistance.

Abstract: In various embodiments, an accelerometer apparatus includes a center member; a resilient member, enclosing the center member; and, a mass member in contact with the resilient member, enclosing the center member; wherein, ambient motion of the apparatus at or beyond a selected threshold causes the resilient member or the mass member to contact the center member, thereby indicating the selected threshold has been met or exceeded. In one embodiment, the resilient member or the mass member contacting the center member closes an electrical circuit, whereby the accelerometer functions as an electrical switch.
