An angular position sensor (24) and method that relies on a stationary- circular array of Hall sensors (18) and a rotatable circular array of magnets (16) arranged about a common axis (22). A periodic and simultaneous reading of all of the Hall sensor outputs is used to determine angular velocity.

An array of optically pumped magnetometers includes an array of vapor cells; and an array of beam splitters. The array of beam splitters is arranged into columns, including a first column, and rows. Each row and each column includes at least two of the beam splitters. The array of beam splitters is configured to receive light into the first column of the array and to distribute that light from the first column into each of the rows and to distribute the light from each of the rows into a plurality of individual light beams directed toward the vapor cells.

A sensor assembly is provided for use in tracking a medical device. The sensor assembly comprises a magnetoresistance sensor capable of providing position and orientation information. In certain implementations, the magnetoresistance position and orientation sensor is originally configured for connection to a substrate using one type of interconnect approach but is modified to be connected using a different interconnect approach.
