摘要: Embodiments describe a receiving element that includes a ferromagnetic structure axially symmetrical around a central axis disposed along a length of the ferromagnetic structure. The ferromagnetic structure includes a groove region defining two end regions on opposing sides of the groove region, where the groove region has a smaller length than the two end regions. The receiving element also includes an inductor coil wound about the groove region of the ferromagnetic structure and in between the two end regions.

摘要: Disclosed herein is an input device having variable make points. More specifically, the various embodiments described herein are directed to an input device having a key, a first button member and a second button member. A dielectric may be positioned between the first button member and the second button member. The key is also associated with a capacitive sensor that is configured to determine a change in capacitance as a distance between the first button member and the second button member changes.
