Abstract
Abstract A rate integrating device includes a torquer in open loop configuration for torquing the device to null and a load connected to the device in closed loop configuration for maintaining the device at null. The load loop includes electrical means whereby the maintenance of the device at null is controlled independent of its dynamic characteristics for increased accuracy and stability.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A sensor system, comprising: a sensor for providing a first torque in response to a sensed condition; means for providing a second torque; a displaceable load; means for combining the first and second torques and the load displacement; a signal generator connected to the combining means and responsive to the combined first and second torques and load displacement for providing a corresponding signal; means connected to the signal generator and responsive to the signal therefrom for providing another signal; means connected to the last mentioned means and connected to the load, and responsive to the signal from the last mentioned means for displacing the load; and the means for providing a second torque including means for providing a third torque in response to command and bias signals, means connected to the signal generator and responsive to the signal therefrom for providing a fourth torque, and means for combining the third and fouth torques to provide the second torque.
Claim 2
Dependent Claim
158 words
A sensor system, comprising: a sensor for providing a first torque in response to a sensed condition; means for providing a second torque; a displaceable load; means for combining the first and second torques and the load displacement; a signal generator connected to the combining means and responsive to the combined first and second torques and load displacement for providing a corresponding signal; means connected to the signal generator and responsive to the signal therefrom for providing another signal; means connected to the last mentioned means and connected to the load, and responsive to the signal from the last mentioned means for displacing the load; and the means for providing a second torque including means for providing a third torque in response to command and bias signals, means connected to the signal generator and responsive to the signal therefrom for providing a fourth torque, and means for combining the third and fouth torques to provide the second torque.
Claim 3
Dependent Claim
34 words
A sensor system as described in claim 1, wherein: the means connected to the signal generator and responsive to the signal therefrom for providing another signal includes the means for providing the fourth torque.
Claim 4
Dependent Claim
69 words
A sensor system as described by claim 1, wherein the means connected to the last mentioned means and connected to the load, and responsive to the signal from the last mentioned means for displacing the load includes: means for integrating the signal from the last mentioned means; and displacing means connected to the integrating means and to the load, and responsive to the integrated signal for displacing the load.
Claim 5
Dependent Claim
30 words
A sensor system as described by claim 1, wherein: the means for combining the first and second torques and the load displacement includes means for summing said torques and displacement.
Claim 6
Dependent Claim
32 words
A sensor system as described by claim 1, wherein: the means for combining the third and fourth torques to provide the second torque includes means for summing said third and fourth torques.
