Extending sockets, formed of accordions generally with buttons attached at their distal ends, for attaching to portable media players or portable media player cases. Cases having attached sockets serve purposes beyond protection of the player, such as managing a headset, attaching to belts or the like, forming stand legs to prop the player at a desired angle, forming grips for gaming, forming a grip for securely holding and manipulating player with one hand, and forming extended legs for wedging players that are phones between the ear and shoulder. The sockets are structured to allow headset cords to be wound around the accordions when the sockets are extended, to prevent the cords from tangling. Space in an attached case may be provided so that the sockets may be partially or fully retracted with headphone cords wrapped around them to save space.

A releasable riser plate assembly is provided for use with a telemark binding. The assembly is mounted to a ski. The assembly includes a base plate interconnecting a front and rear housing, and a release plate mounted over the base plate. Force transmitting members are integrated in the housings to hold the release plate. A toe adapter of the telemark binding is mounted on the release plate. The toe of a ski boot is secured in the toe adapter. Adequate force generated by the boot in either a lateral direction or vertical direction results in disengagement of the release plate from the base plate and housings. Accordingly, the boot separates from the ski. The assembly incorporates a ski brake. The ski brake activates upon separation of the release plate. The release plate is reattached by a step-in motion wherein a front portion of the release plate is positioned under a lip of the front housing, and then the heel of the boot is pressed down against the ski to seat a rear portion of the release plate against the base plate and rear housing.

A voluntary closing prosthetic prehensor includes a locking mechanism which may be locked into any position, and released with a small amount of force. With locking enabled, the prehensor opens and closes normally until the user applies sufficient tension to the prehensor cable after the prehensor has closed upon an object. Then, a lever arm attached to the cable rotates, pulling a second cable which causes an elliptical cam to rotate such that its wider portion presses against a pawl, causing the pawl to rotate into engagement with a toothed sector, locking the prehensor closed. When the user releases the force on the cable, the lever arm is biased to return to its normal position, but the prehensor stays closed because the pawl remains engaged with the sector. The cam includes a ratcheting drum which takes up the slack in the second cable. To release the prehensor, the user applies a small amount of force to the first cable, moving the lever arm and pulling the second cable, which rotates the cam. As it starts to rotate, the cam moves away from the pawl, allowing it to rotate away from the sector. The pawl has two links joined at a pivot. The link engaged with the toothed sector pivots to allow the pawl to rotate away from the sector, pulling the engaged link free. The pawl is biased to retract away from the sector, unlocking the prehensor.

A goniometer for use in measuring angular movements of joints of a human or animal body comprises an elongate body and a plurality of mercury-in-rubber sensors extending longitudinally of the body at locations spaced from one another around the body. The electrical resistance of the sensors varies with varying strain thereof, and a circuit is connected to the sensors for converting variations in the resistance into a measure of the relative angular disposition of the ends of the body.
