Abstract: A hybrid large-area pressure sensor with a capacitive sensor and a resistive sensor integrated thereinto. The sensor includes a first electrode pattern, a second electrode pattern spaced apart from the first electrode pattern by a predetermined distance, a third electrode pattern spaced apart from the second electrode pattern by a predetermined distance, and a controller, wherein a part of the first electrode pattern, a predetermined unit area of the second electrode pattern, and a predetermined unit area of the third electrode pattern form a single unit sensing cell, a change in distance between the first electrode pattern and the second electrode pattern causes a change in the capacitance of the second electrode pattern, a contact between the second electrode pattern and the third electrode pattern causes a change in the resistance of the second electrode pattern.

Abstract: Hundreds of thousands of concrete bridges and hundreds of billions of tons of concrete require characterization with time for corrosion. Accordingly, protocols for rapid testing and improved field characterization systems that automatically triangulate electrical resistivity and half-cell corrosion potential measurements would be beneficial allowing discrete/periodic mapping of a structure to be performed as well as addressing testing for asphalt covered concrete. Further, it is the low frequency impedance of rebar in concrete that correlates to corrosion state but these are normally time consuming vulnerable to noise. Hence, it would be beneficial to provide a means of making low frequency electrical resistivity measurements rapidly. Further, prior art techniques for electrical rebar measurements require electrical connection be made to the rebar which increases measurement complexity/disruption/repair/cost even when no corrosion is identified. Beneficially a method of determining the state of a rebar without electrical contact is taught.

Abstract: A method includes, at a controller, sensing a magnitude of a first force applied to the thumbstick in a substantially downward direction relative to a top portion of the housing while the thumbstick is in the stationary default position, and a magnitude of a second force applied to the thumbstick in the substantially downward direction relative to the top portion of the housing while the thumbstick is in a position other than the stationary default position. The method includes receiving the magnitude of the first and the second force, and determining whether the magnitude of the first force or the second force satisfies a predefined force value. The method further includes providing haptic feedback to the user in response to a determination that the magnitude of the first force or the second force satisfies the predefined force value.
