Abstract: A novel database query and writing engine for rapidly storing, retrieving and modifying large amounts of data on mobile devices is disclosed. The innovative database engine software comprises the creation of a set of files for each table in a database, wherein CRUD (create-retrieve-update-delete) operations are streamlined for mobile or other devices by organizing memory for efficient read and write operations. The set of associated files segregate fixed length and variable length data types for faster seek, read and write operations, and keep track of changes to values and database table schema changes in terms of deletions and insertions of rows and columns. The innovative database engine manages complexities associated with storage and retrieval of large amounts of data, which comprise CRUD operations. In addition, the database engine introduces a dual buffer system to more rapidly process blocks of database memory.

Abstract: A virtual image display system is provided which comprises a non-emissive, reflective microdisplay which forms a source object; an optical system which forms a magnified, virtual image of the source object from light reflected off the microdisplay; a light source system which produces light to illuminate the display system; and an illumination system which forms at least two virtual light sources to illuminate the display system.

Abstract: A display matrix is provided for forming a composite image from a series of sub-images. The display matrix includes a plurality of display elements, each display element including a pixel, and a display circuit electrically connected to the pixel. Each display circuit includes a plurality of memory cells, and a selector for outputting to the pixel data from one memory cell at a time where the plurality of memory cells are non-addressably connected to the selector.

Abstract: A phone accessory which include an insert which can be positioned between a phone and power source. The insert has a first side with a set of electrical contacts which align with electrical contacts on the phone when the phone is attached to the insert. The insert also has a second side with a set of electrical contacts which align with electrical contacts on the power source when the power source is attached to the insert. When the insert is positioned between the phone and the power source, the phone is in electrical communication with the power source through the insert. The insert also includes an insert dataport which couples with a dataport on the phone when the phone is attached to the insert. A virtual image display is attached to the insert and in electrical communication with the insert dataport for receiving image data from the phone through the phone and insert dataports.

Abstract: A display matrix is provided comprising a plurality of display elements, each display element including a pixel, and a display circuit electrically connected to the pixel and at least partially positioned outside of a footprint of the pixel, the display circuit including a plurality of memory cells, and a selector continuously electrically connected to more than one of the plurality of memory cells, the selector outputting to the pixel data from one memory cell at a time.

Abstract: A synthesized virtual image electronic display is provided that includes a microdisplay for forming a source object, a first magnification optic for magnifying the source object to produce a magnified real image, an image synthesizing optic upon which the magnified real image is projected, and a second magnification optic for providing a magnified virtual image of the magnified real image projected on the synthesizing optic. The image synthesizing optic is a diffractive element which provides the display of the present invention with significant optical and ergonomic advantages over that which can be achieved using prior art simple magnification and compound magnification systems.

Abstract: A virtual image display system is provided which is made thinner through the use of an immersed beam splitter, and in one embodiment, total internal reflection. The display system includes an imaging surface on which a source object is formed, a first optical element having a reflective function and a magnification function, a second optical element having a magnification function and an immersed beam splitting element positioned between the first and second optical elements, the immersed beam splitting element including a beam splitter surrounded by an optically transparent material having a refractive index greater than air. An illumination source projects the source object formed at the imaging surface through the optically transparent material to the beam splitter. The beam splitter reflects the projected source object to the first optical element. The first optical element magnifies the projected source object and reflects a magnified virtual image of the projected source object to the beam splitter.

Abstract: A compact virtual image display system is provided which includes a microdisplay; a first magnification optic consisting of three surfaces: a display input surface; a reflective/transmissive surface, and a reflective first magnification element surface; and a second magnification optic. Light forming the source object enters the first magnification optic at the display input surface. The light travels within the first magnification optic such that it is projected to an area on the reflective.backslash.transmissive surface that is at least partially within the full field of view provided by the second magnification optic. The light is directed to the reflective/transmissive surface at a first angle of incidence .theta..sub.SO relative to the reflective/transmissive surface such that the light is internally reflected by the reflective/transmissive surface and directed to the reflective first magnification element surface.
