In a biometric sensor provided for use with an exercise apparatus and having a pair electrodes for sensing a biopotential signal, a common-mode rejection circuit can be used to cancel noise in the signal resulting from various sources including motion of the apparatus.

Noise cancellation mechanism

An information, communication and control system for use in a health club which accumulates data from various types of exercise equipment and permits a number of exercise machines to be raced against one another. The exercise machines are equipped with keyboards from which users can enter data including their handicap (ability level) and the desired length of race. A central controller includes memory for storing data accumulated from the exercise machines and programs. The controller, responsive to the programs and input data, conducts a race between two or more exercise machines and displays the progress of the race on a video monitor. The controller can also be used to set up exercise programs for users on the various machines based on user performance data accumulated from the machines over time.

Exercise equipment information, communication and display system

A control system for a health club which stores user records including user activity data in order to monitor and control use of the club's facilities. A central controller includes a memory for storing the user records including attendance data and accounting data, and a main control which is responsive to the user record data for determining whether a user is authorized to use the club's facilities. The central controller is coupled to various club facilities and equipment such as a computerized scale to prevent use thereof if a user is not authorized. The central controller also stores user history data such as user weight data for the computerized scale to alleviate data storage problems.
