Abstract
A magnetic field sensor for use in a jaw tracking device. The sensor includes a Hall effect generator (110) and a pair of flux concentrators (112, 114). The Hall effect generator has first (116) and second (118) sensing faces disposed on opposite sides of the generator. Each flux concentrator comprises a strip of concentrator material formed into a U-shape, with a pair of opposed, mutually parallel side members (120, 122, 130, 132) interconnected at one end by a cross member (124, 134). The generator and flux concentrators are positioned such that the cross members are adjacent and parallel to the respective sensing faces, with the side members extending away from one another in a direction normal to the sensing faces. The sensor also preferably includes a metal-filled adhesive (140) having a high thermal conductivity bonding each cross member to its respective sensing face.
