摘要： A vibrating inertial rate sensor has operational elements that define axes that are rotationally offset or "skewed" from a node or anti-node reference axis. The skew may be relative to separate node or anti-node reference axes, or take the form of an element that is "split" about the same node axis. Both the drive signal and the sense signal may be resolved from a common set of sensing elements. The drive elements may also operate on a skewed axis angle to rotationally offset the vibration pattern to affect active torquing of the gyroscope. Skewed drive elements may be combined with skewed or split elements on the same device. The skewed sensing scheme may be applied to vibratory systems having one or more node axes. The skewed drive scheme may be applied to vibratory systems having two or more node axes to affect active torquing.

摘要： A drive circuit apparatus for use in generating a drive signal for energizing an actuator about a natural resonant frequency is disclosed. The circuit has a counter that generates a count sequence derived from a drive sense signal. Additionally, a demodulator is further coupled to the counter and generates a voltage level signal from the drive sense signal based on the count sequence. A digital to analog (D/A) converter is coupled to both the counter and demodulator. The D/A converter generates the drive signal in a substantially constant phase relationship with respect to the drive sense signal as derived from the voltage level signal and based on the count sequence. In addition, a method of generating a drive signal for energizing an actuator about a natural resonant frequency is provided.

摘要： An angular rate sensing gyroscope which includes voltage pick-off conductors (50) which are applied to an area of a surface of a piezoelectric resonating element (10) that is subject to substantially zero stress when the gyroscope is rotationally stationary and actuator conductors (40) applied to the resonating element at a location bounded by areas of the resonating element subject to uniform levels of stress when the gyroscope is rotationally stationary, thereby improving the voltage response of the resonating element.
