A position sensor determines the relative positions of two objects and comprises an elastic deformable member provided with a first conductive track and a second conductive track and arranged such that when the objects move relative to each other the resistances of the first conductive track and of the second conductive track vary differently; and means for making a comparative electrical measurement of the first and second conductive tracks. The first and second conductive tracks are substantially coplanar.

In a method for printing a strain gauge on an instrument for force measurement, a deposition mask is applied to a surface of an instrument. With the deposition mask on the surface of the instrument, a strain gauge material is deposited on at least one portion of the surface exposed by aperture(s) in the deposition mask. Additionally, electrically conductive material is deposited along pathways that connect with the deposited strain gauge material. In one embodiment, the strain gauge is printed on surgical forceps.

A linear hot-electron injection technique is provided for a non-volatile memory arrangement. The non-volatile memory is comprised of: a floating gate transistor; a capacitor with a first terminal electrically coupled to the gate node of the floating gate transistor; a current reference circuit electrically coupled to the source node of the floating gate transistor; and a feedback circuit electrically coupled between the source node of the floating gate transistor and a second terminal of the capacitor. The feedback circuit operates to adjust a voltage at the gate node of the floating gate transistor in accordance with a source-to-drain voltage across the floating gate transistor.
