Abstract
Abstract An inertial performance indicator comprises A. a carrier having a downwardly dished upper surface, B. a ball supported on said surface in a rest position, the ball adapted to be bodily displaced out of said rest position in response to predetermined acceleration of the carrier in a generally horizontal direction, and C. means to adjustably support and level said carrier so that said upper surface is approximately level relative to horizontal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
An inertial performance indicator, comprising (a) a carrier having a downwardly dished upper surface, (b) a first ball supported on said surface in a rest position, the ball adapted to be bodily displaced out of said rest position in response to predetermined acceleration of the carrier in a generally horizontal direction, and (c) means to adjustably support and level said carrier so that said upper surface is approximately level relative to horizontal, said means including ball and socket joint elements forming a universal joint below the level of the carrier, (e) said means including a leveling ball rollably supported on a downwardly dished interior surface associated with the lower hemisphere, there being a pointer integral with the carrier and projecting downwardly therefrom to point toward the leveling ball.
Claim 2
Dependent Claim
128 words
An inertial performance indicator, comprising (a) a carrier having a downwardly dished upper surface, (b) a first ball supported on said surface in a rest position, the ball adapted to be bodily displaced out of said rest position in response to predetermined acceleration of the carrier in a generally horizontal direction, and (c) means to adjustably support and level said carrier so that said upper surface is approximately level relative to horizontal, said means including ball and socket joint elements forming a universal joint below the level of the carrier, (e) said means including a leveling ball rollably supported on a downwardly dished interior surface associated with the lower hemisphere, there being a pointer integral with the carrier and projecting downwardly therefrom to point toward the leveling ball.
Claim 3
Dependent Claim
27 words
The indicator of claim 1 wherein said upper surface defines an upwardly opening local recess receiving a lower portion of the first ball at said rest position.
Claim 4
Dependent Claim
20 words
The indicator of claim 1 wherein said recess is defined by locally downwardly tapering annular extent of said upper surface.
Claim 5
Dependent Claim
15 words
The indicator of claim 1 including a transparent upper housing extending over said upper surface.
Claim 6
Dependent Claim
21 words
The indicator of claim 4 wherein said upper housing and said carrier have rim portions which extend in mutually adjacent relation.
Claim 7
Dependent Claim
32 words
The indicator of claim 1 including holder means to hold the ball and socket elements in a selected position of adjustment after relative universal swiveling of one element relative to the other.
Claim 8
Dependent Claim
20 words
The indicator of claim 1 wherein the ball element has the shape of a lower hemisphere peripherally supporting the carrier.
Claim 9
Dependent Claim
136 words
An inertial performance indicator, comprising (a) a carrier having a downwardly dished upper surface, (b) a first ball supported on said surface in a rest position, the ball adapted to be bodily displaced out of said rest position in response to predetermined acceleration of the carrier in a generally horizontal direction, and (c) means to adjustably support and level said carrier so that said upper surface is approximately level relative to horizontal, said means including ball and socket joint elements forming a universal joint below the level of the carrier, (d) the ball element having the shape of a lower hemisphere peripherally supporting the carrier, (e) the socket element comprising an annulus having an annular rim seating the ball element, the ball element being transparent, and there being a level sensor within the transparent ball element.
Claim 10
Dependent Claim
136 words
An inertial performance indicator, comprising (a) a carrier having a downwardly dished upper surface, (b) a first ball supported on said surface in a rest position, the ball adapted to be bodily displaced out of said rest position in response to predetermined acceleration of the carrier in a generally horizontal direction, and (c) means to adjustably support and level said carrier so that said upper surface is approximately level relative to horizontal, said means including ball and socket joint elements forming a universal joint below the level of the carrier, (d) the ball element having the shape of a lower hemisphere peripherally supporting the carrier, (e) the socket element comprising an annulus having an annular rim seating the ball element, the ball element being transparent, and there being a level sensor within the transparent ball element.
