Abstract
Abstract An improved system of the type having a ball or sphere and within it a remote-control powered vehicle, has provisions for determining vehicle orientation for more efficient control including one or more of: transparent ball portions, color ball portions and forward-illuminating spotlight; ability to store the vehicle with the ball inflated is provided by a mercury switch which turns off power when the vehicle is inverted; angle strips improve traction externally and a soft, semi-inflated ball is used for better internal traction between vehicle and ball wall; charging of vehicle batteries through the ball wall is disclosed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
In a system of hollow ball and vehicle with wheels, steering and a power circuit for same, and means for remotely controlling steering and forward-reverse direction of the vehicle, the improvement comprising: means for increasing wheel traction on the ball inner surface comprising: said ball being inflatable and of soft flexible material which when the ball is partially inflated can wrap partially around said wheels for increasing traction area, means for indicating forward orientation of said vehicle for purposes of said remote control, including said ball being at least in part light-conductive, means for illuminating said light conductive part of said ball when said light conductive part is at a particular location generally ahead of said vehicle, said means for illuminating comprising a light on a forward part of said vehicle, and said means for indicating also indicating rotation of said ball and comprising means for modulating said illuminating when the ball is rotating.
Claim 2
Dependent Claim
154 words
In a system of hollow ball and vehicle with wheels, steering and a power circuit for same, and means for remotely controlling steering and forward-reverse direction of the vehicle, the improvement comprising: means for increasing wheel traction on the ball inner surface comprising: said ball being inflatable and of soft flexible material which when the ball is partially inflated can wrap partially around said wheels for increasing traction area, means for indicating forward orientation of said vehicle for purposes of said remote control, including said ball being at least in part light-conductive, means for illuminating said light conductive part of said ball when said light conductive part is at a particular location generally ahead of said vehicle, said means for illuminating comprising a light on a forward part of said vehicle, and said means for indicating also indicating rotation of said ball and comprising means for modulating said illuminating when the ball is rotating.
Claim 3
Dependent Claim
99 words
In a system as recited in claim 1, said means for modulating including color modulation by means of a light conductive ball portion of a different color from said light conductive part, said means for modulating further including ball-traction improving fin structure at spaced locations on the outside of the ball, said fin structure producing less light conduction than said light conductive part when at said particular location, and said means for modulating further including closable opening structure on the ball, said closable opening structure producing less light conduction than said light conductive part when at said particular location.
Claim 4
Dependent Claim
33 words
In a system as recited in claim 2, said closurable-opening construction including a tongue and groove type closure, a guard thereover, and means affixing said tongue and groove type closure to said ball.
Claim 5
Dependent Claim
18 words
In a system as recited in claim 3, said guard and said means affixing including an adhering tape.
Claim 6
Dependent Claim
46 words
In a system as recited in claim 1, a control switch on an upper part of said vehicle, and means for actuating said control switch without deflating said ball, comprising said control switch being accessible for manual operation through the ball when said vehicle is inverted.
Claim 7
Dependent Claim
62 words
In a system as recited in claim 5, said vehicle power circuit including a rechargeable battery, and means for recharging said battery without deflating said ball, comprising first inductive means on said vehicle adjacent a lower portion of said ball, a charging source, and second inductive means on said charging source positionable adjacent said first inductive means for charging said rechargeable battery.
