Abstract: A magnetically operated display unit includes a frame of a color, a plate pivotably mounted on the frame which includes a first surface of a color different from that of the frame and a second surface of a color identical to that of the frame, a magnet embedded in the plate, a U-shaped ferromagnetic element mounted on the frame so that two tips of the magnet are located between two tips of the U-shaped ferromagnetic element, a solenoid mounted on the U-shaped ferromagnetic element and a light emitting diode mounted on the frame. The plate contains a cutout designed for receiving the light emitting diode and one of the tips of the U-shaped ferromagnetic element. The tip of the light emitting diode is located on a level between the plate and the tips of the U-shaped ferromagnetic element. The light emitting diode is visible sufficiently above the surface of the plate so that its light can shine on that surface. Two opposite currents are selectively directed through the solenoid.
Abstract: A motor vehicle headlight reflector and a headlight constructed therefrom, wherein the reflector comprises a plurality of laterally juxtaposed zones bounding transition lines with a break of slope. Each zone has a smooth reflective surface and is adapted to spread light horizontally between two limits obtained in the immediate vicinity of the transition lines. The limits of horizontal spread in each zone varies progressively with displacement along the transition line concerned. The invention also includes a method of making the motor vehicle headlight reflector.
Abstract: A communication system includes a control communication network for transferring control data, and a data communication network for transferring stream data. A communication node is set on the communication system in response to a request on the stream transfer. The communication node is connected to both of the above networks and transfers data via the data communication network under the control based on the control data. The communication node controls access by an application and transfer of stream data by referring to a transfer control table which holds the relation of connection with another control communication node which transfers the common data and the corresponding relation to a control node (application) associated with data transfer defined by the connecting relation.
Abstract: An illumination method and apparatus for machine-vision systems, including a ring-light source (e.g., LEDs arranged in one or more circular rows), and a reflective-ring focusing element. The illumination source exhibits multidirectional ring-illumination properties which are useful for illumination of small components (which are being inspected or measured) without unwanted shadows. One embodiment provides a darkfield illumination system. One embodiment of the present invention uses a strobed (or pulsed) power supply to drive the LEDs. Yet another embodiment of the present invention uses a xenon strobe ring-light source and a backplane slit in place of the row of LEDs 25. In one such xenon strobe embodiment, a color filter is also placed in series with the light path in order to obtain a monochromatic light.
Abstract: A method and a support for supporting a package in a steam sterilizer, featuring support members configured and positioned to support only at least a portion of at least two opposed side edges, but not a side face, of the package. A diamond shape is particularly preferred for the support members as, when rotated at an angle, its facets provide line contact with appropriate side edges of the package.

Abstract: A self-gettering electron field emitter has a first portion formed of a low-work-function material for emitting electrons, and it has an integral second portion that acts both as a low-resistance electrical conductor and as a gettering surface. The self-gettering emitter is formed by disposing a thin film of the low-work-function material parallel to a substrate and by disposing a thin film of the low-resistance gettering material parallel to the substrate and in contact with the thin film of the low-work-function material. The self-gettering emitter is particularly suitable for use in lateral field emission devices. The preferred emitter structure has a tapered edge, with a salient portion of the low-work-function material extending a small distance beyond an edge of the gettering and low resistance material. A fabrication process specially adapted for in situ formation of the self-gettering electron field emitters while fabricating microelectronic field emission devices is also disclosed.
Abstract: A motor vehicle headlamp has a discharge lamp, a reflector and a smooth or nearly smooth cover lens, the reflector being adapted to generate a beam below a cut-off line. At least two masks are associated with the discharge lamp, and define two shadow zones on the reflector; the reflector includes at least two reflective zones for forming portions of the beam below the cut-off line, with different amounts of sideways spreading of the light; and these zones of the reflector are separated by generally radial transition planes, at least some of which extend into the shadow zones. A particular application is to enable wide cruising beams to be produced to European standards without any optical anomalies.
Abstract: A phakic intraocular lens (IOL) for the correction of visual disorders such as myopia, hyperopia, astigmatism and presbyopia. The lens is made from a biocompatible, elastomeric material such as silicone. The lens further includes one or more annular surfaces that protrude from the anterior surface of the lens or surrounds the lens such that when placed in the eye, it makes contact with the iris. As the iris dilates and constricts, the contact with the iris places a centering force on the implanted lens. The lens is not in contact with the natural lens of the eye and floats in the posterior chamber without insult or abrasion to surrounding tissue.
Abstract: A data card, such as a credit or debit card, having first and second sides, wherein the first side includes data card information stored on a magnetic strip and embodied in embossed alpha-numeric indicia, and the second side includes a surface having a series of optically related image lines thereon, and an optically transparent layer attached thereto and forming a lenticular lens, the optically transparent layer and optically related image lines forming a lenticular optical system capable of alternately displaying images.
Abstract: A device useful as a display element has an electron emitter and an anode disposed to receive electrons emitted from the emitter. The anode has surface portions differing in resistivity, providing an electron sink portion at the surface portion of lowest resistivity. A preferred embodiment has a lateral field-emission electron emitter and has an anode formed by processes specially adapted to provide anode portions of differing resistivity, including the electron sink portion. The electron sink portion is preferably disposed at a position laterally spaced apart from the emitting tip of the device's electron emitter.
Abstract: An electron field-emission display comprises one or more display cell structures, each having a field-emission cathode and an anode comprising at least one of several cathodoluminescent phosphors disclosed which are stimulable by electrons of very low energy. The display cell structures may also have gate elements for controlling electron current flowing from cathode to anode when suitable electrical bias voltages are applied. A preferred fabrication process integrates an etch stop with an in situ phosphor formation process. The etch stop precisely defines the depth of an opening in the display cell structure.
Abstract: The invention relates to a headlamp for an automobile vehicle comprising an elliptical reflector, a light source positioned in a region of the first focus of the reflector, a lens, the focus of which is in a region of the second focus of the reflector, and a mask interposed between the reflector and the lens to effect a cut-off of the light beam emitted. A mirror is located in front of the mask and adapted to return direct light rays emitted by the light source onto the front face of the mask which thereby diffuses them towards the lens.
Abstract: An electroluminescent display system for displaying images having an electroluminescent display unit with a plurality of electroluminescent pixels, a receiver for receiving a signal that contains information regarding an image to be displayed on the unit, a signal processor for processing the information contained in the signal and a signal cable to convey the processed signal to the electroluminescent display so as to activate selected pixels. Because of its light weight, small size and flexibility, the electroluminescent display system is conformable to any shaped surfaces and transportable.

Abstract: An automated means for hydrating and packaging a molded hydrophilic contact lens in one of the mold parts used to mold the lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. The hydration carrier is then transported through a plurality of flushing or extraction stations wherein fresh deionized water is introduced into the hydration chambers at each hydration station to flush leachable substances from the hydration chamber. At each flushing station, fresh deionized water is introduced into the hydration chamber to remove previously extracted impurities and the products of hydrolysis.

Abstract: A device for correcting the orientation of a motor vehicle headlight beam has a casing containing an electric motor, a rotatable output shaft and a speed reducer working between the motor shaft and the output shaft of the device, for the purpose of making running adjustments to the beam orientation. The device also includes a manual adjusting knob which is rotatable in the casing, with a selective transmission means between the manual knob and the output shaft, for putting the latter into a reference position when the knob is rotated. The speed reducing motor drive is coupled to the output shaft through a dog clutch which is disengaged, to convert the device from electrical to manual operation, by axial declutching movement of the manual knob.
Abstract: A laser scanning method and system for determining an outline of an object. A laser beam is projected at the object and a surface underlying the object. The surface is configured to reflect the laser beam differently than the object. The laser beam is reflected off the object and the surface producing reflected beams. The reflected beams are received by a control which determines whether the beam was reflected from the object or the surface. By identifying this with the laser position the control can identify the part outline. As the laser beam is scanned over successive positions along the surface, the outline of the object is precisely determined. In a preferred embodiment, the laser scanning system further includes a transparent support for supporting the object a predetermined distance from the surface thereby increasing the scanning resolution and improving the accuracy of the system.
Abstract: Disclosed are thin, flexible electroluminescent lamps. The lamps comprise bubbles of a light emitting material distributed in a matrix.
