| Abstract: |
A device capable of detecting motion, especially extremely small amounts of motion (micromotion) which has three portions: (a) a sensing portion, (b) a detecting portion, and (c) a warning portion: (A) the sensing portion has (1) a micro- to macromotion pathway having a conformation which permits repeated, reciprocal movement from or about a gravitational resting point, of a ball which is in constant contact with it and which is free to move on it in response to external forces; (2) a terminal domain whose conformation requires the ball to be in constant contact with it when the ball is at the gravitational resting point on the pathway, but which also permits the ball to move away from it in response to external forces; both the pathway and the terminal domain being made of a material whose electrical resistance is between 0.8 and 10 times that of copper, where the resistance of copper is given as 1.0; and (3) a ball disposed for repeated, reciprocal movement from or about the gravitational resting point on the pathway and in constant contact with it, the ball being made of a material whose electrical resistance is at least 1000 times that of copper, where the resistance of copper is given as 1.0; (B) the detecting portion has detection circuitry associated with the sensing portion which detects fluctuations in electrical current passing through the sensing portion, and which activates the warning portion of the device when a predetermined change in the electrical current takes place; and (C) the warning portion, which alerts a user of the device, another person, or both, that a micro- to macromotion has been sensed and detected.

First Claim:
Show all 20 claims |
What is claimed is:
1. A micro- to macromotion sensing, detecting and warning device comprising:
(A) a micro- to macromotion sensing portion of said device comprising:
- (1) a micro- to macromotion pathway having a conformation which permits repeated, reciprocal movement from or about a gravitational resting point thereon of a substantially spherical object in constant contact therewith and free to move thereon in response to external forces, a portion of said pathway which is in contact with said spherical object being made of a material whose electrical resistance is between 0.8 and 10 times that of copper, where the resistance of copper is given as 1.0;
- (2) a terminal domain having a conformation which requires said substantially spherical object to be in constant contact therewith when at said resting point on said pathway, but which also permits said substantially spherical object to move away therefrom in response to said external forces, a portion of said terminal domain which is in contact with said spherical object being made of a material whose electrical resistance is between 0.8 and 10 times that of copper, where the resistance of copper is given as 1.0; and
- (3) a substantially spherical object disposed for repeated, reciprocal movement from or about said gravitational resting point on said micro- to macromotion pathway and in constant contact therewith, the portion of said spherical object being in contact with said pathway being made of a material whose electrical resistance is at least 1000 times that of copper, where the resistance of copper is given as 1.0;
(B) a detecting portion of said device for determining the presence of said micro- to macromotion comprising:
- (1) a source of direct current electromotive force of about 12 volts or less, being substantially negative (-) with a positive (+) component of from about 1% to about 3% thereof;
- (2) said substantially spherical object being in electrical contact with the negative terminal of said source of direct current, said terminal being the ground reference in the system, by way of said terminal domain or by way of said micro- to macromotion pathway, such that when said substantially spherical object is at said gravitational resting point of said micro- to macromotion pathway, it is simultaneously in electrical contact with said pathway and with said terminal domain;
- (3) said micro- to macromotion pathway or said terminal domain being in electrical contact with detection circuitry as defined herein, when the other is in electrical contact with said negative terminal of said source of direct current, thereby forming a complete electrical circuit through said substantially spherical object when at said gravitational resting point; and
- (4) detection circuitry associated with said micro- to macromotion sensing portion which detects fluctuations in electrical current passing through said sensing portion, and which activates a warning portion of said device as defined herein when a predetermined change in said electrical current takes place; and
(C) a warning portion of said device for alerting a user of said device, another person, or both, that a micro- to macromotion has been sensed and detected, comprising:
- means for translating electrical current from said detecting portion into a signal which provides useful information to said user of said device, another person, or both.
