Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
An alarm apparatus, capable of being worn by operators of motor vehicles and the like, to signal an undesirable position of one part of the body with respect to another or with respect to a fixed object, comprising: means for providing an electrically produced signal; an electrical power source capable of powering said electric signal means; means responsive to an undesirable position of the body for electrically connecting said electric signal means to said electrical power source, said electrical connection means including two electric switches each being capable of individually electrically connecting said electric signal means to said electrical power source, said switches being positioned to have two distinct planes of operation; and means for securing said electrical connection means to said body.
Claim 2
Dependent Claim
123 words
An alarm apparatus, capable of being worn by operators of motor vehicles and the like, to signal an undesirable position of one part of the body with respect to another or with respect to a fixed object, comprising: means for providing an electrically produced signal; an electrical power source capable of powering said electric signal means; means responsive to an undesirable position of the body for electrically connecting said electric signal means to said electrical power source, said electrical connection means including two electric switches each being capable of individually electrically connecting said electric signal means to said electrical power source, said switches being positioned to have two distinct planes of operation; and means for securing said electrical connection means to said body.
Claim 3
Dependent Claim
84 words
The apparatus of claim 1 wherein said electrical connection means also includes means for maintaining an electrical connection between said electrical power source and said electric signal means for a fixed period of time once a said connection is first provided by one of said switches, independently of further operation of said switches, said maintaining means being connected to the serial connection of said electric signal means and said electrical power source, as well as being connected to said parallel connection of said switches.
Claim 4
Dependent Claim
23 words
The apparatus of claim 2 wherein said electric signal means includes an electric buzzer and wherein said electrical power source includes a battery.
Claim 5
Dependent Claim
66 words
The apparatus of claim 1, wherein said two electric switches include: a soft deformable support; two cavities within said support, each being of similar shape and at a 90° rotated orientation from one another; and two pairs of electrical contacts being situated one pair within each said cavity, said paired electrical contacts being electrically connected in parallel between said power source and said electric signal means.
Claim 6
Dependent Claim
48 words
The apparatus of claim 4, wherein each said cavity includes: a protruding angular projecting wall; a first film of electrically conductive material forming one contact of a said electrical contact pair, said film residing on said protruding wall; and a first electrical connection from said first conductive film.
Claim 7
Dependent Claim
46 words
The apparatus of claim 5, wherein each said cavity further includes a second electrically conductive film covering the wall facing said first film, said second film forming the other contact of a said electrical contact pair; and a second electrical connection from said second conductive film.
Claim 8
Dependent Claim
17 words
The apparatus of claim 1 also including means for anchoring said securing means to said fixed object.
Claim 9
Dependent Claim
39 words
The apparatus of claim 7 wherein said securng means includes a collar having two portions each said portion being connected on an end to said soft deformable support, said portions being connectable to one another on their free ends.
Claim 10
Dependent Claim
46 words
The apparatus of claim 8 wherein said anchoring means includes: a break away hook positionable behind said collar at said connectable free end position when said collar is secured to said body; and a cord attached to said break away hook and to said fixed object.
Claim 11
Dependent Claim
29 words
The apparatus of claim 9 wherein said anchoring means also includes a clamping block, said cord being passed through said block to clamp said cord at a fixed length.
