Abstract
Abstract An inclination sensitive hand controller comprises a generally cylindrical handle having liquid contact switches mounted at different angles of orientation within the handle. The switches are actuated dependent upon the tilting of the handle from a preselected position. A squeeze responsive control switch is mounted in a non-exposed position within the handle. This switch is activated or deactivated upon squeezing of the handle to control connection and disconnection of electrical power to the tilt switches. An exposed finger- depressible switch is mounted at one end of the handle which independently controls other circuits than the circuits controlled by the tilt switches and the squeeze responsive control switch.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
An inclination sensitive control handle, comprising: a generally cylindrical handle controllable by an operator by tilting of said handle from a preselected position, said handle being at least slightly compressible radially inwardly in response to manual squeezing thereof; a plurality of tilt switches mounted within said handle, each of said tilt switches being oriented for actuation or deactuation upon tilting of said handle away from said preselected position; and a squeeze responsive control switch in a nonexposed position within said handle for controllably connecting and disconnecting supply of electrical power to said tilt switches in response to squeezing of said handle.
Claim 2
Dependent Claim
101 words
An inclination sensitive control handle, comprising: a generally cylindrical handle controllable by an operator by tilting of said handle from a preselected position, said handle being at least slightly compressible radially inwardly in response to manual squeezing thereof; a plurality of tilt switches mounted within said handle, each of said tilt switches being oriented for actuation or deactuation upon tilting of said handle away from said preselected position; and a squeeze responsive control switch in a nonexposed position within said handle for controllably connecting and disconnecting supply of electrical power to said tilt switches in response to squeezing of said handle.
Claim 3
Dependent Claim
21 words
The inclination sensitive control handle of claim 1 further including a finger-depressible switch mounted generally at one end of said handle.
Claim 4
Dependent Claim
159 words
An inclination sensitive control handle, comprising: a generally cylindrical handle controllable by an operator by tilting of said handle from a vertical position, said handle being at least slightly compressible radially inwardly in response to manual squeezing thereof; a first tilt switch mounted within said handle for activation upon tilting of said handle generally toward one of four horizontal, orthogonal directions; a second tilt switch mounted within said handle for activation upon tilting of said handle generally toward the second of said directions; a third tilt switch mounted within said handle for activation upon tilting of said handle generally toward the third of said directions; a fourth tilt switch mounted within said handle for activation upon tilting of said handle generally toward the fourth of said directions; and a squeeze responsive control switch in a nonexposed position within said handle and responsive to squeezing of said handle for controlling connection and disconnection of electrical power to said tilt switches.
Claim 5
Dependent Claim
159 words
An inclination sensitive control handle, comprising: a generally cylindrical handle controllable by an operator by tilting of said handle from a vertical position, said handle being at least slightly compressible radially inwardly in response to manual squeezing thereof; a first tilt switch mounted within said handle for activation upon tilting of said handle generally toward one of four horizontal, orthogonal directions; a second tilt switch mounted within said handle for activation upon tilting of said handle generally toward the second of said directions; a third tilt switch mounted within said handle for activation upon tilting of said handle generally toward the third of said directions; a fourth tilt switch mounted within said handle for activation upon tilting of said handle generally toward the fourth of said directions; and a squeeze responsive control switch in a nonexposed position within said handle and responsive to squeezing of said handle for controlling connection and disconnection of electrical power to said tilt switches.
Claim 6
Dependent Claim
27 words
The inclination sensitive control handle of claim 3 wherein said tilt switches are securely mounted within said handle at respective preselected angles relative to a vertical axis.
Claim 7
Dependent Claim
30 words
The inclination sensitive control handle of claim 4 wherein said first and third tilt switches are disposed generally at a right angle relative to said second and fourth tilt switches.
Claim 8
Dependent Claim
29 words
The inclination sensitive control handle of claim 3 wherein said squeeze responsive control switch is responsive to squeezing of said handle to connect electrical power to said tilt switches.
Claim 9
Dependent Claim
29 words
The inclination sensitive control handle of claim 3 wherein said squeeze responsive control switch is responsive to squeezing of said handle to disconnect electrical power to said tilt switches.
Claim 10
Dependent Claim
21 words

Claim 11
Dependent Claim
102 words
An inclination sensitive control handle, comprising: a generally cylindrical handle controllable by an operator for tilting movement from a generally vertical orientation to a tilted position disposed angularly relative to a vertical axis, said handle being at least slightly compressible radially inwardly in response to manual squeezing thereof; at least three tilt responsive switches mounted within said handle for actuation and deactuation in response to tilting movement of said handle; and a squeeze responsive control switch in a nonexposed position within said handle and responsive to squeezing of said handle for controlling connection and disconnection of electrical power to said tilt switches.
Claim 12
Dependent Claim
102 words
An inclination sensitive control handle, comprising: a generally cylindrical handle controllable by an operator for tilting movement from a generally vertical orientation to a tilted position disposed angularly relative to a vertical axis, said handle being at least slightly compressible radially inwardly in response to manual squeezing thereof; at least three tilt responsive switches mounted within said handle for actuation and deactuation in response to tilting movement of said handle; and a squeeze responsive control switch in a nonexposed position within said handle and responsive to squeezing of said handle for controlling connection and disconnection of electrical power to said tilt switches.
