Claim 3

The display system as in claim 1 further including: sensor means associated with the bicycle for providing a series of signals according to the altitude of the bicycle and representative of the altitude; means for providing said altitude signals to said central processing unit means.

Claim 4

The display system as in claim 1 wherein said central processing unit means further includes: means to compare current performance data with user selected data so as to determine whether the present performance is faster or slower than the selected data and to generate an output display signal representative of the result of such comparison to the Input/Output means for display to the user.

Claim 5

The display system as in claim 1 wherein said Input/Output means further includes: means for producing an audible tone operative in accord with said output display signal generated by said central processing unit.

Claim 6

The display system as in claim 1 wherein said Input/Output means further includes: means for connecting said central processing unit means and memory means to an external computer system, so that said external computer system may read and write data into the areas of memory used by said central processing unit means.

Claim 7

A user controlled display system for an exercise machine for monitoring and comparing electrical signals representative of the present performance of a user of the machine, against a selected prior performance, comprising: sensing means associated with the machine and adapted for providing a series of signals representative of a preselected set of factors chosen to represent the present performance of the user on the machine; clocking means providing a plurality of timing signals representative of the elapsed time from the beginning of the performance; Input/Output means for receiving user input and selection data, and generating a corresponding input signal representative thereof, and for generating a display signal in response to a received output display signal to display data to the user; Central Processing Unit means receiving as input said series of signals representative of a preselected set of factors chosen to represent the present performance of the user on the machine, elapsed time and user generated input signals, for retrievably storing each of said distance travelled, elapsed time and user generated input signals in a user selected portion of a memory means as a set of detailed performance data signals representative of at least the elapsed time and each of the preselected set of factors chosen to represent the present performance of the user on the machine, for a plurality of points during the present performance of the user, said central processing unit means operating under a predetermined set of user controlled instructions to store said set of performance data for each performance of the user in said memory means, and compare said set of performance data signals against a stored user selected set of performance data representing a selected performance, and generate an output display signal representative of a user selected comparison metric therebetween to said Input/Output means.

Claim 8

A user controlled display system for an exercise machine for monitoring and comparing electrical signals representative of the present performance of a user of the machine, against a selected prior performance, comprising: sensing means associated with the machine and adapted for providing a series of signals representative of a preselected set of factors chosen to represent the present performance of the user on the machine; clocking means providing a plurality of timing signals representative of the elapsed time from the beginning of the performance; Input/Output means for receiving user input and selection data, and generating a corresponding input signal representative thereof, and for generating a display signal in response to a received output display signal to display data to the user; Central Processing Unit means receiving as input said series of signals representative of a preselected set of factors chosen to represent the present performance of the user on the machine, elapsed time and user generated input signals, for retrievably storing each of said distance travelled, elapsed time and user generated input signals in a user selected portion of a memory means as a set of detailed performance data signals representative of at least the elapsed time and each of the preselected set of factors chosen to represent the present performance of the user on the machine, for a plurality of points during the present performance of the user, said central processing unit means operating under a predetermined set of user controlled instructions to store said set of performance data for each performance of the user in said memory means, and compare said set of performance data signals against a stored user selected set of performance data representing a selected performance, and generate an output display signal representative of a user selected comparison metric therebetween to said Input/Output means.

Claim 9

The display system as in claim 6 wherein said Input/Output means further includes: means for producing an audible tone operative in accord with said output display signal generated by said central processing unit.

Claim 10

The display system as in claim 6 wherein said Input/Output means further includes: means for connecting said central processing unit means and memory means to an external computer system, so that said external computer system may read and write data into the areas of memory used by said central processing unit means.
