Circuits, systems, and methods for monitoring and reporting foot impact, foot placement, shoe life, and other running/walking characteristics
First Claim
1. A foot impact monitoring system comprising:
- an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; and
an impact alert circuit that is configured to regulate a background sound component in response to measured impacts, and to combine the background sound component with a music component generated by a music player to generate a combined signal that is played to the person to audibly indicate to the person how much impact occurred from the foot striking the surface.

Abstract
Various embodiments of the present invention provide an electronic virtual running/walking coach that notifies a person as to how hard the person'"'"'s feet have been impacting a surface, notifies the person as to whether the person'"'"'s feet are impacting a surface at a proper relative distance from the body and/or at a proper side-to-side angle, and/or notifies the person as to how much cushioning life remains in a pair of shoes. When the notifications are provided to the person during the running/walking activity, the person can respond by taking immediate actions to adjust the foot placement relative to the body and/or adjust the level of foot impact to an acceptable level by varying the speed, step distance, and/or posture while running/walking and/or by selecting among different available surfaces on which to run/walk. A person may also more accurately determine when a particular pair of shoes should be replaced because they no longer provide a sufficient level of cushioning to compensate for the levels of foot impact that are occurring.

1. A foot impact monitoring system comprising:
-
an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; and an impact alert circuit that is configured to regulate a background sound component in response to measured impacts, and to combine the background sound component with a music component generated by a music player to generate a combined signal that is played to the person to audibly indicate to the person how much impact occurred from the foot striking the surface. - View Dependent Claims (2, 3, 4, 5, 6, 8, 10, 11, 13, 14, 15, 16, 18, 22, 23, 24, 25, 26, 27)

7. A foot impact monitoring system comprising:
-
an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; a sound generation device that is configured to generate sound to the person, an impact alert circuit that is configured to; generate at least one baseline threshold level in response to measured impacts; respond to a presently measured impact exceeding one of the at least one baseline threshold level by causing the sound generation device to generate a foot impact warning sound to the person; increase loudness and/or modify a defined tone characteristic of the foot impact warning sound generated by the sound generation device in response to a presently measured impact exceeding one of the at least one baseline threshold level by an increased amount to audibly indicate to the person when the presently measured impact from the foot striking the surface has increased; and decrease loudness and/or oppositely modify the defined tone characteristic of the foot impact warning sound generated by the sound generation device in response to a presently measured impact exceeding one of the at least one baseline threshold level by a decreased amount to audibly indicate to the person when the presently measured impact from the foot striking the surface has decreased. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)

9. A foot impact monitoring system comprising:
-
an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; a display device configured to display indicia to the person; and an impact alert circuit that is configured to; generate at least one baseline threshold level in response to measured impacts; respond to a presently measured impact exceeding one of the at least one baseline threshold level by causing the display device to display a foot impact warning indicia to the person; and cause the display device to modify the foot impact warning indicia to indicate when a presently measured impact is exceeding one of the at least one baseline threshold level by a greater amount, and to indicate when a presently measured impact is exceeding one of the at least one baseline threshold level by a lesser amount to provide visual guidance to the person of the measured impact from the foot striking the surface. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

12. A foot impact monitoring system comprising:
-
an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; and an impact alert circuit that is configured to; generate a baseline threshold level in response to rate of change of measurements of an impact; and respond to a present rate of change of measurements of an impact exceeding the baseline threshold level by generating an audible warning through a sound generation device and/or a visual warning through a display device. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)

17. A foot impact monitoring system comprising:
-
an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; and an impact alert circuit that is configured to; monitor the measured impacts while the person is walking/running over the life of at least one of the person'"'"'s shoes; respond to a calibration signal from a person by generating a baseline threshold level in response to rate of change of measurements of impacts; and generate an indication of when the shoe has become worn-out in response to a comparison of rate of change of measurements of at least one impact to the baseline threshold level. - View Dependent Claims (66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80)

19. A foot impact monitoring system comprising:
-
an impact measurement circuit configured to measure impact from a foot repetitively striking a surface while a person is walking/running; and an impact alert circuit that is configured to; determine from characteristics of the measured impact when the person is placing the foot improperly forward when striking the surface and resulting in excessive undesirable slowing forces exerted on the foot and retarding forward movement of the person; and generate an audible/visual warning to the person that a first improper foot placement condition exists responsive to the determination that the person is placing the foot improperly forward when striking the surface. - View Dependent Claims (20, 21, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110)
