Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A force measuring system for a ground traversing vehicle adaptable to measure either acceleration, deacceleration and inclination, or centrifugal force, said force measuring system comprising, in combination: a vehicle; motion sensing means mounted in said vehicle for sensing lateral or fore-and-aft forces within the vehicle and creating pneumatic pressure in response thereto, said motion sensing means including a generally horizontally disposed, U-shaped fluid filled tube having upturned end portions; a pneumatic pressure indicating means mounted within said vehicle; means interconnecting one end portion of said generally U-shaped tube with said pneumatic pressure indicating means, wherein the transverse orientation of said tube relative to the longitudinal axis of said vehicle results in the pressure indicating means indicating centrifugal force acting on said vehicle, and wherein orientation of said tube generally parallel to the longitudinal axis of said vehicle results in said pneumatic indicating means indicating acceleration, deacceleration and inclination, and; an orifice means in said interconnecting means for bleeding the pressure therein to atmospheric pressure over an extended period of time when the force measuring system is in a static condition.
Claim 2
Dependent Claim
180 words
A force measuring system for a ground traversing vehicle adaptable to measure either acceleration, deacceleration and inclination, or centrifugal force, said force measuring system comprising, in combination: a vehicle; motion sensing means mounted in said vehicle for sensing lateral or fore-and-aft forces within the vehicle and creating pneumatic pressure in response thereto, said motion sensing means including a generally horizontally disposed, U-shaped fluid filled tube having upturned end portions; a pneumatic pressure indicating means mounted within said vehicle; means interconnecting one end portion of said generally U-shaped tube with said pneumatic pressure indicating means, wherein the transverse orientation of said tube relative to the longitudinal axis of said vehicle results in the pressure indicating means indicating centrifugal force acting on said vehicle, and wherein orientation of said tube generally parallel to the longitudinal axis of said vehicle results in said pneumatic indicating means indicating acceleration, deacceleration and inclination, and; an orifice means in said interconnecting means for bleeding the pressure therein to atmospheric pressure over an extended period of time when the force measuring system is in a static condition.
Claim 3
Dependent Claim
29 words
The force measuring means of claim 1 wherein one of said up-turned ends is open to the atmosphere and the other end is operatively connected to said connecting means.
Claim 4
Dependent Claim
25 words
The force measuring means of claim 1 wherein the means for operatively connecting the sensing means to the indicating means is a tube like line.
Claim 5
Dependent Claim
59 words
A force measuring system, as recited in claim 1, wherein the portion of said generally horizontal, U-shaped tube extending between the two upturned ends is substantially longer than either of said two upturned ends thereby being of relatively shallow depth and particularly suitable for mounting in either traverse or longitudinal orientations relative to the longitudinal axis of said vehicle.
Claim 6
Dependent Claim
29 words
The force measuring system, as recited in claim 4, wherein in the longitudinal orientation, said generally horizontally disposed tube is disposed adjacent a central console formed within the vehicle.
Claim 7
Dependent Claim
30 words
A force measuring system, as recited in claim 4, wherein in the traverse orientation said generally horizontal tube is aligned with and disposed adjacent the rear axis of said vehicle.
