Abstract
Abstract An electronic device particularly useful as a jogging computer comprises presetting means for presetting the size of the user's step, an inertia sensor sensing each step, a central clock, and a microprocessor computing the user's speed and distance travelled, and displaying same on an electronic display. The described device further includes a pacer which produces a tone at a preselected rate to aid the jogger in pacing himself. A second embodiment of the invention is described for attachment to a bicycle for measuring speed and distance travelled of the bicycle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
143 words
An electronic device for measuring distance traversed by a body in motion per unit time, comprising: A. a housing; B. presetting means carried by said housing for presetting a distance constant corresponding to the distance per increment of the motion; C. a sensor carried by said housing for sensing each increment of motion and outputting a sensor signal therefor; D. an electronic display carried by said housing; and E. an electronic data processor disposed within said housing and including: (1) a central clock measuring time in a real-time manner, (2) means for storing said preset distance constant, (3) means including said central clock for computing the time intervals between successive sensor signals, (4) means for computing measurements of speed by multiplying said latter time intervals by the stored distance constant (5) and means for feeding said measurements of speed to said electronic display.
Claim 2
Dependent Claim
143 words
An electronic device for measuring distance traversed by a body in motion per unit time, comprising: A. a housing; B. presetting means carried by said housing for presetting a distance constant corresponding to the distance per increment of the motion; C. a sensor carried by said housing for sensing each increment of motion and outputting a sensor signal therefor; D. an electronic display carried by said housing; and E. an electronic data processor disposed within said housing and including: (1) a central clock measuring time in a real-time manner, (2) means for storing said preset distance constant, (3) means including said central clock for computing the time intervals between successive sensor signals, (4) means for computing measurements of speed by multiplying said latter time intervals by the stored distance constant (5) and means for feeding said measurements of speed to said electronic display.
Claim 3
Dependent Claim
53 words
An electronic device according to claim 1, wherein said means for computing measurements of speed computes same as a weighted average over a predetermined number of increments of motion, by each previously-computed speed by a weighted number "n," adding the instantaneous speed multiplied by another weighted number "m," and then dividing by "n+m."
Claim 4
Dependent Claim
82 words
An electronic device according to claim 1, wherein said presetting means further includes means for presetting a pacer rate constant corresponding to a predetermined number of said increments of motion per unit time, said electronic data processor further including means for storing said pacer rate constant, a tone generator, and means for actuating said tone generator by the stored pacer-rate constant to cause same to sound an audible tone for each of said predetermined number of increments of motion per unit time.
Claim 5
Dependent Claim
46 words
An electronic device according to claim 1, wherein said electronic data processor further includes means for multiplying the total number of sensor signals by the stored distance constant to produce a measurement of total distance traversed, and for feeding said latter measurement to said electronic display.
Claim 6
Dependent Claim
36 words
An electronic device according to claim 1, wherein said sensor is a mechanical inertia device including a mechanical element which is displaced by inertia for each of said increments of motion to output said sensor signal.
Claim 7
Dependent Claim
37 words
An electronic device according to claim 5, wherein said inertia device includes a cantilever-mounted metal leaf biassed out of engagement with a fixed metal contact and displaced thereagainst by inertia for each of said increments of motion.
Claim 8
Dependent Claim
36 words
An electronic device according to claim 1, wherein said presetting means for presetting the distance constant presets information corresponding to the user's step size when jogging, whereby the device may be used as a jogging computer.
Claim 9
Dependent Claim
19 words
An electronic device according to claim 7, wherein said housing carries a clip for attaching same to the user.
Claim 10
Dependent Claim
21 words
An electronic device according to claim 7, wherein said housing is carried by a wrist-band for attaching same to the user.
Claim 11
Dependent Claim
42 words
An electronic device according to claim 1, wherein said presetting means for presetting the distance constant presets information corresponding to the diameter of a wheel in a wheeled vehicle, whereby the device may be used as a speedometer for the wheeled vehicle.
Claim 12
Dependent Claim
26 words
An electronic device according to claim 10, wherein the wheeled vehicle is a bicycle, and said housing includes a clip for clipping same to the bicycle.
Claim 13
Dependent Claim
62 words
An electronic device according to claim 1, wherein said presetting means further includes means for presetting a specified time-delay, said electronic data processor further including means for storing said time-delay, a tone generator, and means for comparing the stored time-delay with the central clock and for actuating said tone generator when the time of the central clock corresponds to the stored time-delay.
Claim 14
Dependent Claim
41 words
An electronic device according to claim 1, wherein said presetting means includes a keyboard comprising a plurality of buttons, said keyboard further including a Start/Stop button which starts and stops all measuring functions, and a Reset button which resets the device.
Claim 15
Dependent Claim
20 words
An electronic device according to claim 1, wherein said electronic data processor is a microprocessor including a preprogrammed control unit.
