Abstract: An exercise system for use with a computing device to modify and demonstrate an exercise. The exercise system may be used to modify exercises and to collect and track data based on exercise performance. Modifications to exercises may include range of motion, timing, and exercise routine modifications to customize exercises for use by a patient or athlete. A force sensing device can also be used with the exercise system to measure and track exercise data.

Abstract: A system for communicating according to a standard communication protocol for process control includes a plurality of interconnected computers. The system includes a module that permits communication of information between computers that communicate with process control equipment. The system also includes a module that permits a primary controlling machine to communicate with computers that communicate with process control equipment, and that permits a secondary controlling machine to take the place of the primary controlling machine when the primary controlling machine is unavailable. The system further includes a module that aggregates requests for information directed to one computer that communicates with a piece of process control equipment, communicates with the computer and obtains the information, and delivers the information to each of the requesters. The standard communication protocol for process control can be OPC, and the communicated information can be one or more process control parameters.
