摘要:
A transducer package 20 includes a substrate 32 having a first axis of symmetry 36 and a second axis of symmetry 38 arranged orthogonal to the first axis of symmetry 36. At least a first sensor 50 and a second sensor 52 each of which are symmetrically arranged on the substrate 32 relative to one of the first and second axes of symmetry 36 and 38.The first and second sensors 50 and 52 are adapted to detect movement parallel to the other of the first and second axes of symmetry 36 and 38. The first sensor 50 is adapted to detect movement over a first sensing range and the second sensor 52 is adapted to detect movement over a second sensing range, the second sensing range differing from the first sensing range.
