Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
A radio transmitter for providing broadcast control signals to a remote model craft that are related to the setting of manual controls with there being one manual control for each control signal comprising a first manual control means for producing a first electrical command having a value related to its setting, a second manual control means for producing a second electrical command having a value related to its setting and a third manual control means for producing a third electrical command having a value related to its setting, means interconnecting the first control means and the second control means for altering the value of the second command in accordance with changes in the value of the first command, means interconnecting the first control means and the third control means for altering the value of the third command in accordance with changes in the first command and means for broadcasting control signals related to the values of each of the commands.
Claim 2
Dependent Claim
160 words
A radio transmitter for providing broadcast control signals to a remote model craft that are related to the setting of manual controls with there being one manual control for each control signal comprising a first manual control means for producing a first electrical command having a value related to its setting, a second manual control means for producing a second electrical command having a value related to its setting and a third manual control means for producing a third electrical command having a value related to its setting, means interconnecting the first control means and the second control means for altering the value of the second command in accordance with changes in the value of the first command, means interconnecting the first control means and the third control means for altering the value of the third command in accordance with changes in the first command and means for broadcasting control signals related to the values of each of the commands.
Claim 3
Dependent Claim
64 words
The invention as defined in claim 1 in which the interconnecting means between the first and second control means normally provides a related alteration between the values of the two commands and in which the interconnecting means further includes means for momentarily increasing the extent of alteration of the value of the second command when the value of the first command is changed abruptly.
Claim 4
Dependent Claim
34 words
The invention as defined in claim 2 in which the means for increasing includes means that are rendered operative only for abrupt alterations in the value of the first command in one direction only.
Claim 5
Dependent Claim
48 words
The invention as defined in claim 2 in which the interconnecting means between the first and second control means includes means for inverting the direction of the alteration in the value of the second command with respect to the direction of alteration of value in the first command.
Claim 6
Dependent Claim
65 words
The invention as defined in claim 2 in which the first control means includes means for selecting either direction of alteration of the value of the first command for the same manual movement and in which the interconnecting means between the first and third control means includes means for altering the value of the third command only in one direction for the same manual movement.
Claim 7
Dependent Claim
45 words
The invention as defined in claim 1 in which the interconnecting means between the first and second control means includes means for adjusting the proportion of the altering of the value of the second command with an alteration in the value of the first command.
Claim 8
Dependent Claim
49 words
The invention as defined in claim 1 in which the first control means alters the value of the first command about a neutral value and in which the third control means includes means for adjusting the value of the third command for the neutral value of the first voltage.
Claim 9
Dependent Claim
32 words
The invention as defined in claim 1 in which the interconnecting means between the first and second control means includes switch means for disconnecting the second control from the first control means.
Claim 10
Dependent Claim
34 words
The invention as defined in claim 1 in which the interconnecting means between the first control and the third control includes switch means for disconnecting the third control means from the first control means.
Claim 11
Dependent Claim
31 words
The invention as defined in claim 1 in which the second control means has a manually movable member for altering the value of the second command independently of the first control.
Claim 12
Dependent Claim
31 words
The invention as defined in claim 1 in which the third control means has a manually movable member for altering the value of the third command independently of the first control.
Claim 13
Dependent Claim
141 words
A radio transmitter for providing broadcast control signals to a remote model craft that are related to the setting of manual controls with there being one manual control for each control signal comprising a first manual control means for producing a first electrical command having a value related to its setting, a second manual control means for producing a second electrical command having a value related to its setting, means interconnecting the first control means and the second control means for altering the value of the second command in accordance with changes in the value of the first command, said interconnecting means including means for momentarily altering the second command an extent that is also related to the rapidity of change of the value of the first command and means for broadcasting control signals related to the value of the commands.
Claim 14
Dependent Claim
141 words
A radio transmitter for providing broadcast control signals to a remote model craft that are related to the setting of manual controls with there being one manual control for each control signal comprising a first manual control means for producing a first electrical command having a value related to its setting, a second manual control means for producing a second electrical command having a value related to its setting, means interconnecting the first control means and the second control means for altering the value of the second command in accordance with changes in the value of the first command, said interconnecting means including means for momentarily altering the second command an extent that is also related to the rapidity of change of the value of the first command and means for broadcasting control signals related to the value of the commands.
