Abstract
Abstract This invention relates to devices for detecting motion of the human body, and more particularly, to means for detecting when selected portions of the human body start into motion as, for example, to monitor the ''''timing'''' of athletes, such as baseball players. In one embodiment of the device there is included means for changing the on-off state of an electrical switch in response to the selected portion of the body going through a change in state of motion, the output of the associated electrical circuit controlled by the switch actuating a means of sensory stimulation, such as an auditory device or a light signal. A preferred form of this embodiment is a tubular mercury switch affixed to the body portion which is connected through an electrical circuit to a buzzer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
A device for indicating that a selected portion of the human body has come into motion in a selected direction comprising an electrical switch means adapted for affixation to said portion of said human body which changes its on-off state in response to motion of said selected portions of said body in said selected direction but not counterdirectionally thereto, and electrically actuated means for producing a sensory indication that the on-off state of said switch means has changed.
Claim 2
Independent Claim
78 words
A device for indicating that a selected portion of the human body has come into motion in a selected direction comprising an electrical switch means adapted for affixation to said portion of said human body which changes its on-off state in response to motion of said selected portions of said body in said selected direction but not counterdirectionally thereto, and electrically actuated means for producing a sensory indication that the on-off state of said switch means has changed.
Claim 3
Dependent Claim
34 words
The device described in claim 1 in which said switch means is a switch in which electrical contact points become electrically interconnected as a result of the change in position of an associated ball.
Claim 4
Dependent Claim
16 words
The device described in claim 1 in which said sensory indication means produces an auditory response.
Claim 5
Dependent Claim
34 words
The device described in claim 3 in which said switch means is a switch in which electrical contact points become electrically interconnected as a result of the change in position of an associated ball.
Claim 6
Dependent Claim
19 words
The device described in claim 1 in which the response sensitivity of said switch means may be selectively varied.
Claim 7
Dependent Claim
34 words
The device described in claim 1 wherein said switch means is a tubular switch, the response sensitivity of which may be selectively varied by varying the inclination of said tube with respect to horizontal.
Claim 8
Dependent Claim
15 words
The device described in claim 6 wherein said sensory indication means produces an auditory response.
Claim 9
Dependent Claim
25 words
The device described in claim 7 wherein said sensory indication means as well as said switch means is adapted for affixation to said human body.
Claim 10
Dependent Claim
96 words
The device described in claim 1 in combination with a second device for indicating that a second selected portion of the human body has come into motion in a selected direction, said second device comprising an electrical switch means adapted for affixation to said second portion of said human body which changes its on-off state in response to motion of said selected portion of said body in said selected direction but not counterdirectionally thereto, and a second electrically actuated means for producing a sensory indication that the on-off state of said second switch means has changed.
Claim 11
Dependent Claim
28 words
The combination described in claim 9 in which said second sensory indication means produces a response which is distinguishable to the senses from said first sensory indication means.
Claim 12
Dependent Claim
19 words
The combination described in claim 10 in which at least one of said sensory indication means produce auditory responses.
Claim 13
Dependent Claim
22 words
The combination described in claim 10 in which the response sensitivity of at least one of said switches may be selectively varied.
Claim 14
Dependent Claim
30 words
The combination described in claim 10 in which both of said sensory indication means produce auditory responses and the response sensitivity of both of said switches may be selectively varied.
