    Abstract: A compact and inexpensive method and apparatus for illuminating and acquiring a digital image of a biometric feature such as a fingerprint, palm print, footprint, or some subset or multiple of such features. A source of illumination (11) is introduced into an exposed edge of a transparent optical window (13) that is essentially smooth and generally flat with spaced apart surfaces. The illumination propagates between the surfaces of a flat or slightly curved transparent window (13) via total internal reflection (15) to obliquely illuminate a biometric feature (12) when in contact with the window (13). A digital camera (17) views the obliquely illuminated biometric feature (12) to record an image of it which can then be compared with registered images for matching and control purposes.

    Abstract: An electro-optic display (100) comprising a backplane (102), a layer (112) of electro-optic material and a protective layer (128) capable of absorbing ultra-violet radiation and disposed on the opposed side of the layer (112) of electro-optic material from the backplane (102), is provided with an edge seal (130). The protective layer (128) extends beyond the layer (112) of electro-optic material, thus leaving a peripheral gap between the protective layer (128) and the backplane (102). To form the edge seal (130) an uncured edge sealing material curable by radiation transmitted by the protective layer (128) is placed in the gap and cured by transmitting radiation through the protective layer (128).

    Abstract: An electro-optic display comprises a bistable electro-optic medium, a plurality of pixel electrodes, with associated non-linear elements, and a common electrode, disposed on opposed sides of the electro-optic medium. The display has a writing mode, in which at least two different voltages are applied to different pixel electrodes, and a non-writing mode in which the voltages applied to the pixel electrodes are controlled so that any image previously written on the electro-optic medium is substantially maintained. The display is arranged to apply to the common electrode a first voltage when the display is in its writing mode and a second voltage, different from the first voltage, when the display is in its non-writing mode.
