This provides a plurality of novel features that can be applied variously to a reader. In one embodiment, the light pipe is constructed from durable polycarbonate for increased shock resistance and can define a rectangular cross section. The chamfered end of the light pipe is textured or frosted to further diffuse refracted light passing through the end so as to present a more even effect. The conical / tapered diffuser within the light pipe is illuminated by a reflector with a white textured surface that reflects a plurality of rearward-directed illumination sources back into the diffuser. The reflector can define a predetermined cross section that directs further light into the forwardmost, remote regions of the diffuser to generate a better spread of light and alleviate spotting effects. The textured surface on the chamfered light pipe end can be employed to better project indicator light. The illumination sources are arranged in a ring at the inner end of the pipe, and can be multi-colored sources that respond to the controller to project and appropriate color and / or blink in an appropriate pattern to indicate various conditions, such as read success or failure. The controller is adapted to provide indications between image acquisitions. The controller can operate individual portions of the ring so that only corresponding portions of the light pipe perimeter are illuminated in a particular color (quadrants, for example) at a given time. Different quadrants may be simultaneously illuminated in different colors in one example

Various embodiments of the invention allow for increased shock robustness in gyroscopes. In certain embodiments, immunity against undesired forces that corrupt signal output is provided by a chessboard-pattern architecture of proof masses that provides a second layer of differential signals not present in existing designs. Masses are aligned parallel to each other in a two-by-two configuration with two orthogonal symmetry axes. The masses are driven to oscillate in such a way that each mass moves anti-parallel to an adjacent proof mass. In some embodiments of the invention, a mechanical joint system interconnects proof masses to suppress displacements due to mechanical disturbances, while permitting displacements due to Coriolis forces to prevented erroneous sensor signals.

A head suspension assembly couples a baseplate to a rotatable load through a planar triangular piezo microactuator for effecting hingeless rotation of the load. The microactuator expands, responsive to an excitation voltage, with greater magnitude in one direction than in another direction normal to the first direction, resulting in an angular movement of the hypotenuse thereby rotating the load. The upper surface of the microactuator is grounded to a bottom surface of the baseplate or load beam to position the microactuator lead connection surface closest to the load to facilitate trace routing. A load beam grounding surface may be raised to accommodate the microactuator and fix the lead connection surface on a common plane with the unraised surface to further minimize trace routing and provide access for bonding the trace to the load beam.
