Abstract

A shoe wear out sensor includes at least one detector for sensing a physical metric that changes as a sole of a shoe wears out, a processor configured to process the physical metric over time to determine if the shoe is worn out, and an alarm for informing a user of the shoe when the sole is worn out. A body bar sensing system includes a housing with at least one detector for sensing a physical metric that indicates a repetition movement of the housing when attached to the body bar, a processor for processing the physical metric over time to determine repetitions thereof, and a display for informing a user of the repetitions. A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

Claims

1-43. -43. (canceled)

44. A system for assessing activity and displaying a unitless activity value, comprising:

a detector for sensing activity of a user;

a processor for processing sensed activity data from the detector;

a display for displaying the unitless activity value; and

an enclosure for housing the detector and the processor;

wherein the processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

45. The system of claim 44, further comprising a battery.

46. The system of claim 44, further comprising a button wherein a user of the system may press the button indicate start of an activity period.

47. The system of claim 44, wherein the button is mounted within the enclosure and accessible externally

48. The system of claim 44, wherein the processor detects the start of an activity period automatically.

49. The system of claim 44, wherein the display is within the enclosure and visible externally to the enclosure.

50. The system of claim 44, further comprising a wireless transmitter for transmitting the unitless activity value to the display, the display being remote from the enclosure.

51. A method for determining a unitless activity value for a desired period of activity, comprising:

clearing a period accumulator prior to the start of the activity period;

sampling a detector periodically to obtain data;

processing the data to determine a number representative of the sampling period;

adding the number to the period accumulator;

determining the unitless activity value based upon the period accumulator, a maximum activity number and a display range; and

displaying the unitless activity value;

wherein the steps of sampling, processing, and adding are repeated until data is sampled for the desired period of activity.

52. A method of assessing activity unitlessly, comprising:

detecting motion of a user;

processing detected motion, over time, to determine an activity value;

ratioing the activity value to a maximum activity value; and

reporting a scaled unitless activity value to the user based upon the ratio and a scale.

53. The method of claim 52, wherein detecting comprises using at least accelerometer.

54. The method of claim 52, wherein processing comprises determining power spectral density over a frequency range.

55. The method of claim 52, wherein the maximum activity value corresponds to predetermined activity value of a professional athlete.

56. The method of claim 52, wherein the scale comprises 0 to 10 or 0 to 100.

57. A software product comprising instructions, stored on computer-readable media, wherein the instructions, when executed by a computer, perform steps for determining a unitless activity value for a desired period of activity, comprising:

instructions for detecting motion of a user;

instructions for processing detected motion, over time, to determine an activity value;

instructions for ratioing the activity value to a maximum activity value; and

instructions for reporting a scaled unitless activity value to the user based upon the ratio and a scale.
