Abstract
Abstract A freestanding multidirectional control device for use in controlling video display images in electronic game machines comprises a handle member connected by a multiconductor cable to electric circuitry in the game machine. The handle member contains two pairs of gravity switches electrically connected to separate output signal conductors in the cable. The pairs of switches are mutually normal along the vertical axis of the handle member. The switches in each pair are oppositely inclined from vertical so that tilting the handle member one way produces an output signal on one of the conductors and tilting it in the opposite direction produces such a signal on a different conductor. The pairs of switches can be either single-ended, two-position tilt switches or double-ended, three-position tilt switches. At least one of the liquid contact switches may contain at least one electrode comprising a length of electrically resistive material to form a variable resistance electrical conduction path.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
335 words
A multidirectional control device for generating electrical control signals for a spatially controlled electrical apparatus, comprising: a handle member having a nominal vertical axis defining a handle position such that the control device is not actuated; a first gravity switch having a first switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle member in a first direction away from said vertical axis and toward said first switch axis actuates said first switch; a second gravity switch having a second switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle member in a second direction away from said vertical axis and toward said second switch axis actuates said second switch; a third gravity switch having a third switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle oppositely of said first direction actuates said third switch; and a fourth gravity switch having a fourth switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle oppositely of said second direction actuates said fourth switch; said switches each including an electrode electrically connected to a separate output signal line to said controlled apparatus and mutually-independent switch closure means operable for actuating each switch independently of the other; said first and second switches having their axes extending at an angle to one another such that their output signal lines provide separate directional control signals to the controlled apparatus which correspond to X and Y variables in an X-Y plane and simultaneously provide both of said separate control signals when the handle is tilted in a direction angularly intermediate said first and second directions; and said third and fourth switches having their axes positioned at an angle to one another such that their output signal lines provide separate directional control signals to the controlled apparatus which correspond to negative X and Y variables in said X-Y plane.
Claim 2
Dependent Claim

A multidirectional control device for generating electrical control signals for a spatially controlled electrical apparatus, comprising: a handle member having a nominal vertical axis defining a handle position such that the control device is not actuated; a first gravity switch having a first switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle member in a first direction away from said vertical axis and toward said first switch axis actuates said first switch; a second gravity switch having a second switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle member in a second direction away from said vertical axis and toward said second switch axis actuates said second switch; a third gravity switch having a third switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle oppositely of said first direction actuates said third switch; and a fourth gravity switch having a fourth switch axis positioned in said handle at an angle from the vertical axis such that tilting the handle oppositely of said second direction actuates said fourth switch; said switches each including an electrode electrically connected to a separate output signal line to said controlled apparatus and mutually-independent switch closure means operable for actuating each switch independently of the other; said first and second switches having their axes extending at an angle to one another such that their output signal lines provide separate directional control signals to the controlled apparatus which correspond to X and Y variables in an X-Y plane and simultaneously provide both of said separate control signals when the handle is tilted in a direction angularly intermediate said first and second directions; and said third and fourth switches having their axes positioned at an angle to one another such that their output signal lines provide separate directional control signals to the controlled apparatus which correspond to negative X and Y variables in said X-Y plane.
Claim 3
Dependent Claim
17 words
A device according to claim 1 in which each of said switches is a liquid contact switch.
Claim 4
Dependent Claim
34 words
A device according to claim 2 in which the first and third switches and the second and fourth switches are defined by two double-ended, three-position liquid contact switches positioned substantially normal to one another.
Claim 5
Dependent Claim
82 words
A device according to claim 3 in which at least one of said double-ended liquid contact switches comprises a tube concavely curved in an upward direction, and at least one of said electrodes comprises a length of electrically resistive material positioned and arranged in the tube so as to be bridged by a pool of liquid conductor at different lengthwise positions to form a variable resistance electrical conduction path as the handle member is tilted at angles of different magnitudes from vertical.
Claim 6
Dependent Claim
76 words
A joystick controller according to claim 1, in which the handle member comprises a freestanding elongated handle member having a nominal vertical axis extending along its length; the switches each being normally deactuated when the vertical axis of the handle member is parallel to the force of gravity; and at least one of the switches being positioned in the handle member so as to tilt therewith substantially about an axis of rotation of the human hand.
Claim 7
Dependent Claim
37 words
A controller according to claim 5 in which said first and third switches are positioned within a vertically central portion of the handle so as to lie within the palm of said hand when gripped for operation.
Claim 8
Dependent Claim
48 words
A controller according to claim 1 including a pushbutton switch means positioned atop the handle member for thumb manipulation, the pushbutton means being connected to a fifth output signal line to said controlled apparatus for providing a control signal thereto which is independent of the directional control signals.
