摘要： A self-processing film unit including a sheet-like photosensitive film component as provided with a liquid applicator holding a supply of low viscosity processing liquid that is to be applied to a given area of an outer surface of the film component, following its exposure, to initiate processing. The applicator comprises a liquid and air impervious sheet carrying on one surface thereof means holding a substantially uniformly distributed supply of processing liquid. The applicator is initially provided on one end of the film component in a releasably sealed folded configuration wherein the impervious sheet forms an impervious enclosure about the liquid holding means and it is movable therefrom to an unsealed extended configuration to locate the liquid holding means in liquid yielding contact with the given area of the film component outer surface.

摘要： A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data rack and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.

摘要： Variable power eyeglasses of many shapes can be manufactured having a frame, a pair of lens assemblies and a linear actuation mechanism. Each lens assembly includes: a rigid substrate; a membrane support spaced from the rigid substrate; a flexible seal extending between the rigid substrate and the membrane support, where the flexible seal acts as a hinge at a first section and acts as a spring by allowing relative motion between the rigid substrate and the membrane support at a second section; a transparent elastomeric membrane sealed around a periphery to the membrane support; and a transparent liquid filling the space between the rigid substrate and the membrane forming a liquid lens. The linear actuation mechanism causes relative motion between the membrane and the rigid substrate so that both optical and prismatic power of the liquid lens changes by varying a force applied to the flexible sealing means at the second section. The linear actuation mechanism is positioned within a plane of the lens assemblies and includes: a pair of sliders connected via a wire passing through a tube mounted onto the frame; a pair of cams with one of the cams attached to each end of the pair of sliders; and a pair of cam followers responsive to the cams causing relative motion in response to movement of the sliders.

摘要： A plurality of electrostatic discharge protection devices are disclosed for use with semiconductor chip packaging such as surface mount chip packages wherein the electrostatic discharge protection devices have shorting arms that extend outward from the electrostatic discharge protection device to make contact with connector pins on the semiconductor chip package such that an electrical connection is made between all of the connector pins of the semiconductor chip package thereby creating a short circuit across the connector pins of the semiconductor chip package to protect the semiconductor chip package from electrostatic discharge. In one embodiment, the electrostatic discharge protection device automatically withdraws the shorting connection upon insertion of the semiconductor chip package onto a printed circuit board. In other embodiments the electrostatic discharge protection device is manually operated to remove the short upon mechanical movement of the device.

摘要： In a laser light pump, a multiplicity of micromanipulators adjust the positions of a cylindrical lens and line of optical fiber ends relative to each other and relative to a light source composed of a line of laser diode facets. Each micromanipulator achieves extremely fine resolution by imposing a vernier or differential screw arrangement into a flexure ratio divider, and thereby multiplying its resolving capability. The vernier screw arrangement spreads two members of different stiffnesses, and the stiffer one of the members moves the lens or the line of fiber ends.

摘要： A device is provided including a flexible sheet having extents encompassing at least a circular area, said flexible sheet doubled-over upon itself through the center of the circular area such that the resultant respective halves of said circular area overlap and form a semicircular field of view; and a sleeve for maintaining the overlapping configuration of said doubled-over flexible sheet, yet allowing said flexible sheet to be displaced about the center of said circular area within the doubled-over configuration. In a particular embodiment, the encompassed circular area of said flexible sheet has at least one light-transmissive region within the circular area, such that transmission of light through the aforementioned field of view can be varied by said displacement of the flexible sheet within said doubled-over configuration. Such embodiment, when employing a polarizing sheet as said flexible sheet, can be used as a variable light transmission device.

摘要： An electrostatic discharge protection device is disclosed which automatically connects selected connector pins of a semiconductor chip package ("SCP") or connectors on printed circuit boards such that the connector pins are held at a common voltage until insertion of the SCP into a receptor or until insertion of a cable into the connector which overcomes an internal resilient bias of the electrostatic discharge protection device causing the common connection to be removed. Removal of the SCP from the receptor or the cable from its connector removes the force which overcomes the bias, thereby reestablishing the common electrical connection thus automatically moving the electrostatic discharge protection device between inoperative and operative positions.

摘要： An electronic imaging module is disclosed which is removably insertable into a photographic camera for reversibly converting the camera into an electronic imaging camera. The electronic imaging module includes a sensing unit, a processing unit, and a coupling unit. The sensing unit detects an object image and converts the image to a corresponding electrical signal. The processing unit, which is configured for location within the camera's film cassette holder, includes a storage unit for storing the electrical signal and a transmission link for transmitting the electrical signal to external devices such as a control unit or a base unit. The coupling unit couples the sensing unit to the processor unit. The coupling unit is adjustable to ensure that the sensing unit is in alignment with the camera optical path and the film plane and the processing unit is secured within the film cassette holder.
