Abstract

A racing system for a group of exercise machines is disclosed. The race is entirely flexible, in that each exercise unit communicates electronically with all of the other potential racing units. Any user may offer a race, accept or reject another user'"'"'s race offer, or join a race during a limited countdown period. More than one race can be underway. For cost reduction, a daisy chain hookup is used, in which each unit'"'"'s microprocessor has an input port receiving message flow from the output port of the preceding unit, and an output port transmitting message flow to the input port of the following unit. The racing function is controlled by the same microprocessor which is embedded in each exercise machine as the controller for that machine, receiving commands from the user and feedback from the machine.

Claims

1. A racing network of exercise machines in which each machine has its own embedded computer for machine control purposes, and in which racing functions are controlled by such machine embedded computers, comprising:

means for providing intercommunication among the machine-embedded computers without intervention of a non-embedded computer;

each machine embedded computer including all of the following;

means for offering a racing goal to the other embedded computers;

means for accepting a racing goal offered by another embedded computer;

means responsive to such an acceptance for starting a race;

means for transmitting to the other embedded computers the information disclosing the racing progress of the machine containing the transmitting computer; and

means for receiving from the other embedded computers information disclosing the racing progress of each machine involved in the race.

2. The exercise machine network of claim 1, which also comprises:

means for displaying at each machine in the race the positions in the race of all machine sin the race.

3. The exercise machine network of claim 1 which comprises:

means for permitting a plurality of unrelated races to be conducted simultaneously.

4. The exercise machine network of claim 1, in which each embedded computer has a transmitting port connected to a receiving port of a second embedded computer, and a receiving port connected to a transmitting port of a third embedded computer.

5. The exercise machine network of claim 1, which also comprises:

a host computer separate from the embedded computers; and

means for transmitting to, and receiving from, the host computer messages other than racing-related messages.

20. The exercise machine network of claim 1 in which the machines simulate stair climbing, each of which machines comprises:

means for causing the exercise machine to substantially maintain a selected climbing speed; and

means under control of the machine user for selecting at any time a different climbing speed.

6. In a network of exercise machines, each of which has an embedded microprocessor which controls its machine in accordance with user-created command signals and machine-created feedback signals, each such microprocessor having an input port and an output port for communication with other microprocessors, a method of providing racing options for the users of the respective machine, comprising:

permitting each user to initiate a racing offer at the user'"'"'s microprocessor;

transmitting that offer to the other microprocessors in the network;

allowing each user to accept or change a racing offer from another user;

allowing each user to initiate a race by accepting the then current racing offer;

allowing each user to join or not join a race which has been offered and accepted;

compiling at each microprocessor the information disclosing the progress of its machine in an ongoing race; and

conveying such information from the microprocessor in each machine to all other machine embedded microprocessors in the network.

7. The method of claim 6 which also includes the steps of:

entering racing information from the network only in those microprocessors engaged in the same race; and

displaying visually the positions for all users involved in a given race at the exercise machine of each such user.

8. The method of claim 6 which also includes:

permitting users not engaged in a given race to initiate and engage in a separate concurrent race.

9. An exercise machine having a microprocessor which includes (a) means for receiving user command signals and machine feedback signals, and (b) means for communicating with one or more microprocessors included in similar exercise machines, the microprocessor having hardware and software for racing, comprising:

means for electronically receiving and transmitting racing messages in communication with the other microprocessor(s);

means for electronically initiating racing messages, including the suggesting of a goal for a proposed race to the other microprocessor(s);

means for electronically responding to racing messages, including the accepting via the microprocessor of a racing goal proposed by another microprocessor;

means for electronically synchronizing the start of a race in response to an acceptance of a suggest racing goal;

means for exchanging racing information with the other microprocessor(s) disclosing their relative positions in an ongoing race; and

means for displaying such information so that each user'"'"'s position in an ongoing race is readily apparent.

10. The exercise machine and microprocessor of claim 9 which also comprises:

means for electronically responding to a proposed racing goal from another microprocessor by raising or lowering the goal in predetermined increments.

11. The exercise machine and microprocessor of claim 9 in which the racing messages which the microprocessor may initiate or respond to include a token message, an offer message, a join message, and a progress message.
