Abstract: A key with extending wings. The with at least one wing that open when the key is not properly installed and the at least one wing retract into the body of the key when the key has been properly inserted regardless of the viewing angle of the key. The key identifies improper insertion and include a spring-loaded pin and inner shaft that engages into aligned locating holes in an inversion bench. In addition to the visual appearance, a blind user can feel the sides to the key to determine if the key has been properly inserted into the inversion bench.

Abstract: For many inversion benches, a user must temporarily lock their ankles into the bench prior to inversion. If the ankles are not properly locked into the bench, the user can slide or fall out of the bench and cause injury. The safety key provides a clear visual indication that the key has been properly inserted regardless of the viewing angle before inversion of the bench begins. The safety key identifies improper insertion and include a spring loaded pin and inner shaft that engages into aligned locating holes in the inversions bench. The safety pin has two wings that fold, extend or tip from the body of key. In addition to the visual appearance, a user who is completely blind can also feel the sides to the key to determine if the key has been properly inserted into the inversion bench.

Abstract: An exercise system for integrating exercise related information of a user from an exercise device, includes a portable remote control and a server. The portable remote control provides a control channel for receiving the exercise related information from a control module of the exercise device via a wireless link. The portable remote control further includes a user interface being customized for enabling the user to directly control an operation of the exercise device through the user interface. The server is linked to the portable remote control for receiving the exercise related information from the portable remote control when the workout is completed, wherein the server is arranged for storing and analyzing the exercise related information so as to minimize the exercised related information to be accumulatively stored in the portable remote control.
