Intertial sensor that includes fluids

A sensor system comprising:

• a container having a first end and a second end that is opposite the first end, where the container comprises:
• a first fluid that is adjacent to the first end of the container;
• a second fluid that is adjacent to the second end of the container;
• a third fluid that is positioned between the first fluid and the second fluid, where density of the third fluid is greater than densities of the first fluid and the second fluid, and further where the first fluid is separated from the second fluid in the container by the third fluid;
• and
• a sensor apparatus including a pressure transducer adapted to output data that is indicative of acceleration of a platform that includes the sensor system, the pressure transducer at least partially seals the container at the first end of the container, and further where the data is pressure data that is representative of a pressure at the first end of the container.

A sensor system comprising:

• an accelerometer, where the accelerometer comprises:
• a container that has a first end and a second end that is opposite the first end, where the container comprises:
• first fluid that is adjacent to the first end of the container, where the first fluid has a first density;
• second fluid that is adjacent to the second end of the container, where the second fluid has the first density;
• and
• third fluid that is positioned between the first fluid and the second fluid in the container, where the third fluid has a second density that is greater than the first density, and further where the first fluid is separated from the second fluid in the container by the third fluid;
• and
• a first sensor apparatus that that is adapted to output data that is indicative of acceleration of a platform that includes the accelerometer in a direction that extends through the first end and the second end, where the data is based upon compression of one of the first fluid or the second fluid by the third fluid;
• a gyroscope, where the gyroscope comprises:
• a hollow ring, where the hollow ring comprises a fourth fluid and a fifth fluid, where the fourth fluid has a third density, the fifth fluid has a fourth density, where the third density is greater than the fourth density;
• and
• a second sensor apparatus that is adapted to output location data that is indicative of locations of the fourth fluid in the hollow ring relative to the second sensor apparatus over time;
• and
• processing circuitry that is adapted to:
• compute acceleration data for the platform, where the acceleration data is indicative of acceleration of the platform in the direction based upon the first signal output by the first sensor apparatus;
• and
• compute motion data that is indictive of at least one of direction of rotation or velocity of rotation of the platform about an axis that extends orthogonally through a center of the hollow ring.
