  • Patent number: 8786520
    Abstract: Various embodiments of the present invention provide for systems and apparatuses directed toward using a display panel to processes display information and non-display information. Further embodiments, utilize a display panel in conjunction with a contact lens assembly configured to process the display information. In one embodiment of the invention, a display system is provided, comprising: a display panel disposed on a head-borne apparatus such that when a viewer is wearing the head-borne apparatus, the display panel is positioned in close proximity to an eye of the viewer such that the eye is unable to focus on the display panel unassisted; and a contact lens having focusing optics that assists the eye in focusing on the display panel. Within the display system, the display panel has pixels and is configured without focusing optics, thereby allowing light emitted by the pixels to diverge in an unfocused manner.

  • Publication number: 20080042052
    Abstract: A MEMS oscillator, such as a MEMS scanner, has an improved and simplified drive scheme and structure. Drive impulses may be transmitted to an oscillating mass via torque through the support arms. For multi-axis oscillators drive signals for two or more axes may be superimposed by a driver circuit and transmitted to the MEMS oscillator. The oscillator responds in each axis according to its resonance frequency in that axis. The oscillator may be driven resonantly in some or all axes. Improved load distribution results in reduced deformation. A simplified structure offers multi-axis oscillation using a single moving body. Another structure directly drives a plurality of moving bodies. Another structure eliminates actuators from one or more moving bodies, those bodies being driven by their support arms.
