Abstract: Device and method for providing inertial indications with high accuracy using micro inertial sensors with inherent very small size and low accuracy. The device and method of the invention disclose use of the cluster of multiple micro inertial sensors to receive from the multiple sensors an equivalent single inertial indication with high accuracy based on the multiple independent indications and mathematical manipulations for averaging the plurality of single readings and for eliminating common deviations based, for example, on measurements of the deviation of the single readings.

Abstract: A Helmet Mounted Display (HMD) system, to be mounted on a helmet of a user, includes a tinted visor, coupled with the helmet, located in front of the face of the user when the tinted visor is in an operative position. The tinted visor further includes a patch, which is located in front of an eye of the user. The patch has greater light transmission than the rest of the tinted visor. The HMD system includes an image generator, coupled with the helmet, generating an image to be displayed to the user. The HMD system further includes an optical combiner, coupled with the helmet, and located substantially on the optical axis of the user's eye. The combiner reflects the generated image toward the eye, and transfers light rays of an outside scene toward the eye.
