Abstract: Embodiments of the present invention are directed to security systems for securing an item of merchandise from theft or unauthorized removal. For example, the security system may include a sensor configured to be coupled to the item of merchandise, wherein the sensor includes an electrical connector. The security system also includes a base configured to removably support the sensor thereon, wherein the base includes an electronics module having a connector. The connector of the sensor and the connector of the electronics module are configured to electrically connect with one another when the sensor is supported on the base, and the sensor is configured to detect unauthorized removal of the item of merchandise from the sensor.

Abstract: Disclosed herein is a method for creating a casted form of a residual limb, having a very smooth internal surface and a precisely capturing and reflecting the detailed topology of the limb. The cast can be used to create a faithfully accurate positive replica of the residual limb, which in turn can be used to create a comfortable prosthetic socket that, when used for a weight-bearing limb, evenly distributes the weight on all weight-bearing surfaces of the limb.

Abstract: A simple, inexpensive prosthetic foot is provided incorporating a cushioned ankle including an ankle block formed of a resilient material or bladder having desired compliance and energy return characteristics. The ankle block is sandwiched between a foot element and an ankle element. One or more openings extends through the ankle block with a substantially transverse orientation relative to a forward walking motion. The size and shape of these openings, as well as the insertion of different types of stiffeners therein, provide desired performance characteristics to the ankle block. When the ankle block takes the form of one or more inflatable bladders, the pressure within these bladders is individually controlled by valves to provide desired performance characteristics to different portions of the prosthetic foot. A pump system can also be used to control and generate fluid pressure into these bladders.

Abstract: An impact-absorbing shock module comprises two pylons telescopingly engaged to permit axial and rotational motion therebetween. A resilient element, such as a spring-fluid combination, a plurality of interconnected disks, or a Belleville spring, provides axial shock absorption. A tubular torque-resisting cuff provides rotational resistance, or torsion-resistance. A fluid valve is optionally provided so that the fluid pressure may be varied to adjust the torsion resistance.

Abstract: The invention provides a cushioned ankle prosthetic foot and a cosmesis having a slot between the big toe and adjacent toe to allow the amputee to wear thong sandals and the like. The cushioning desirably provides a smooth and more natural-feeling rollover from a heel-strike to a toe-off position and/or improved dynamic response characteristics. Advantageously, the prosthetic foot is configured so that it can be used as either a right or a left foot. Moreover, the cosmesis includes a toe reinforcement strap to desirably provide improved wear resistance to the cosmesis.
