    摘要: A one-way optical communication system adapted for vehicular use. A light-readable indicia (35) is embedded in a window or mounted on an exterior portion of a moving motor vehicle (10). The indicia (15) is transparent to visible light and is reflective to infrared or ultraviolet light, making it generally invisible to the unaided human eye. A beam (30) of infrared or ultraviolet light located in a fixed position remote from the moving vehicle illuminates the indicia and portions of the beam are reflected from the illuminated indicia in a representative pattern. The reflected beam is detected by a fixed sensor (25), which provides an electrical signal. The signal is analyzed to determine the identity of the motor vehicle.

    摘要: A multipoint electrical interconnection (10) provides a plurality of electrical pathways between electrically conductive hooks (15) on a substrate (12) and an electrical component (50). A plurality of electrically conductive hooks generally formed in the shape of a `J` have a head portion (20) affixed to the substrate such that a hook portion (17) protrudes above the substrate. An electrically conductive portion of a component is disposed against the substrate such that it contacts at least three of the electrically conductive hooks and deforms the hooks. The deformed hooks provide a spring force to effect a multipoint electrical connection.

    摘要: An automated method of predicting the number of defects that will occur during the manufacturing of a new electronic assembly design on a specific assembly line. Defective components are counted (214) as they are manufactured on an assembly line (210). The counted defects are stored in a historical database (220) and the defect rate is calculated. A bill of material for the new electronic design (230) is enumerated and information associated with each component is extracted from a library database (240) into a quality forecasting engine (250). The quality forecasting engine imports the enumerated bill of material and imports the stored defect rate from the historical database to perform a calculation of a predicted number of defects (260) for said new electronic assembly using the extracted library information.

    摘要: A liquid crystal display device (11) is made by sputtering a layer of indium-tin oxide and copper on a transparent substrate. This metal layer is photodelineated to form a pattern of electrodes (17) and heating elements (81), the heating elements being interlaced between the electrodes. The heating elements are converted to a more resistive form by applying a constant voltage signal to only the heating elements in an oxygen-containing atmosphere. The assembled LCD has the heating elements on the inside of the display, so that when the heating elements are pulsed, they heat only a portion of the liquid crystal fluid in the immediate proximity. The heaters are activated by a signal from a display driver.

    摘要: The preferred housing includes an integrally molded thermoplastic base (102) and cover (104) assembly. The cover is joined to the base by a living hinge (106) and a peripheral wall (108) extends around the perimeter of the base. In one embodiment, the antenna is a wire loop (204), the wire being wound in an external circumferential groove (202A) in the peripheral wall or, alternatively, integrally molded into the peripheral wall. Other embodiments use printed circuit loop antenna patterns that are preferably vacuum deposited directly onto the thermoplastic base and/or cover. When the antenna pattern is disposed on both the cover and the base, a portion of the antenna (e.g., 1002K) is also disposed on the hinge to join the main portions of the antenna on the base and cover. In one embodiment of the printed circuit loop antenna, the plane of the loop lies parallel to the base and may include one or more turns or loops (e.g., 402C, E, G and J). In another embodiment, the loop includes a 90 degree bend (e.g., 504) and both planes of the loop lie perpendicular to the base. In still another embodiment, the loop includes three 90 degree bends, a crossover at one of the bends (e.g., at 704), and all four planes of the loop lie perpendicular to the base.

    摘要: A portable battery charger (102) for use with a variety of battery packs (106) is capable of determining and applying the appropriate charge voltage and current. Electronic circuitry (128) within the portable battery charger identifies the type of battery pack to be charged and selects the appropriate set of battery banks (120) in the charger. Sensors (132) determine the state of charge of the battery pack and a controller (128) controls the functions of the charger. A multiplicity of connectors (314) on the portable battery charger are provided to allow connection to a variety of battery packs. The charger first identifies the type of battery pack and determines the charging profile to be used to charge the battery pack. The charging profile is set in the portable charger by selecting the appropriate sources of electrical power, and the battery pack is then appropriately charged.

    摘要: Printed circuit patterns are photolithographically defined on a three dimensional "projection" surface (204) of a printed circuit substrate (202) using a projection image aligner and a photomask (210) having a planar image (210A). The geometry of the projection is restricted such that the slope of the projection surface, as measured at any point on the projection surface and relative to a reference plane which is parallel to the focal plane of the projection image aligner, is less than 90 degrees. A solution of photoresist includes a photoresist solvent, a fluorosurfactant and an aromatic hydrocarbon solvent, and is preferably sprayed over the projection surface. In one method of manufacture, the printed circuit substrate is moved from one position to another during the exposure of the photoresist layer (206). In another method, after a first portion of the projection surface is exposed by a first photomask (502), a second photomask (504) is substituted and the remainder of the projection surface exposed. In still another method, a photomask having a plurality of planar images (604A, 604B and 606A) each image being positioned parallel to the others but separated by a small distance, is used to simultaneously exposed the entire projection surface.

    摘要: A process for designing and optimally fabricating a plastic object begins by creating a surface model (215) of the object on a digital computer. The surface model contains information about the exterior of the product. A set of constraints (222) that are based on physical attributes of the product and resources available to make the product is defined, and is used to determine an optimum path (223) through a set of manufacturing processes (230) by selecting certain of those processes. A precedence relationship between the selected processes creates a set of interconnected activities. The surface model is processed (224) to convert the databank supporting the model to information that is usable by the selected processes, and this information is sent to the selected processes. Each process performs an activity in accordance with the defined precedence relationship, so that an output of the last one of the selected processes is the plastic object (235). Techniques such as surface modeling, solids modeling, stereolithography, CNC machining, and RIM molding are linked together and a common database is used to create a process of rapidly realizing a product.

    摘要: A process for molding dimensionally accurate plastic articles using a low pressure injection molding technique. The process utilizes a two-piece silicone rubber mold having a cavity representative of the shape of the article to be molded. The mold is substantially encased on all sides in a rigid mold box to prevent deformation of the cavity during the molding process (10). The mold box and the encased mold are placed in a vacuum chamber, and a vacuum is drawn on the chamber to evacuate the cavity (20). A predetermined amount of a reactive mixture is simultaneously mixed and injected under pressure into the mold to form the plastic article (30). The amount of material injected is sufficient to fill the cavity but not sufficient to distort the cavity. The chamber is vented (40) and the mold is removed from the mold box (50). The mold is flexed in order to remove the plastic article from the mold (60).
