Abstract: The health of components of an asset is proactively monitored. A sensor network provides a collection of metrics from a plurality of components of an asset. The collection of metrics includes a set of metrics corresponding to each component, and the set of metrics measures at least one operating characteristic, e.g. temperature, of the corresponding component. A component algorithm processing system receives the collection of metrics and determines a relationship between each set of metrics corresponding to each component and the collection of metrics corresponding to the plurality of components. The component algorithm processing system determines if the relationships indicate a health problem with at least one of the components. The metrics can be further analyzed to determine sensor faults, the remaining life, and the short-term and long-term health of each component. For example, the monitoring system can be applied to the plurality of planetaries on a light armored vehicle.

Abstract: An oscillatory rate sensor is described for sensing rotation about the “z-axis”. It is tuning-fork in nature with structural linkages and dynamics such that fundamental anti-phase oscillation of two proof masses is accomplished by virtue of the mechanical linkages.

Abstract: An oscillatory angular rate MEMS sensor is described for sensing rotation about the “Z-axis”. Embodiments are either coupled-mass tuning-fork or single oscillating-mass in nature. The sensor includes mechanical and electrical function integration, and is preferably manufactured by a unique MEMS fabrication process.

Abstract: A sensor for an electrostatic detector including an elongated vibratory element supported at a mechanical node at one end in the manner of a cantilever beam, a sensitive electrode on the vibratory element near the other end and adapted to be disposed toward an electrical charge, field or potential being measured, and a driver transducer on the vibratory element for vibrating the element in a direction to vary the capacitive coupling between the electrode and the electrical charge, field or potential being measured. The driver transducer is at a location along the beam and is operated at a vibratory frequency such that a virtual mechanical node appears along the beam. This, in turn, reduces vibration at the mechanical attachment node so that the degree of stiffness of the mechanical node does not affect the operating frequency and/or the displacement at the free end of the cantilever.
