20150211895 | INDUCTIVE SENSING INCLUDING INDUCTANCE MULTIPLICATION WITH SERIES CONNECTED COILS - Inductive position sensing uses inductance multiplication with series connected sensor coils. In one embodiment, a first sensing domain area is established in a first target plane using first and second sensor coils disposed on a longitudinal axis, on opposite sides of the first target plane and connected in series, so that a series-combined inductance is a multiple of a sum of the respective first and second coil inductances. Target position within the first sensing domain area of the first target plane is detected based on the series-combined inductance of the first and second coils, which changes as the target moves within the first sensing domain area of the first target plane. Further sensitivity can be achieved by additional coils, series connected on the same longitudinal axis, each coil pair defining a sensing area on a respective target plane intermediate the coils. | 07-30-2015 |
