Abstract: An electronic device may include a connector having a connector body and conductive pins extending outwardly from the connector body, and a circuit board having a dielectric layer, and spaced apart female contacts extending therein. Each female contact may include a conductive tubular via, a core within the conductive tubular via, and a conductive cup having a lower end abutting and joined to the conductive tubular via and an upper end defining a recess receiving a corresponding conductive pin of the connector. The conductive cup may have an outer diameter greater than an outer diameter of the conductive tubular via.

Abstract: A putting training device. The device comprises a surface over which a golfer executes a putting stroke, an electric field generator, an electric field detector, a plurality of electrodes responsive to the electric field generator each for producing an electric field and wherein as the golfer executes the putting stroke one or more of the electric fields is perturbed, and wherein the electric field detector detects the perturbed electric field to determine parameters related to putter head movement.
