Abstract: The present invention provides an antenna interlock system comprising an upper housing and a lower housing. The upper housing has first and second interlock tabs disposed along its interior wall, which correspond to third and fourth interlock tabs disposed along the interior wall of the lower housing, the interlock tabs each having an aperture shaped to closely receive the antenna unit. The interlock tabs are disposed relative to each other such that when the upper and lower housings are assembled together, the apertures in the interlock tabs together define a pathway for receiving the antenna unit, and such that when the antenna unit is inserted through the antenna opening and into the receiving apertures, the antenna unit and the interlock tabs hold the upper and lower housing together.

Abstract: This invention pertains to an apparatus for a drug delivery system to administer topical ophthalmic drug preparations. The apparatus relates to an optical gauging assembly which, when combined with or coupled to any standard topical ophthalmic drug dispensing unit, enables the user to view a target, visually align the dispenser tip, and administer an eye drop with precision. There is also a visual mechanism by which the dispenser tip is prevented from gaining too close proximity and contacting the eye, thus preventing contamination of the medication and its dispenser.

Abstract: A lighting system for use in a conveyer system used for work piece assembly comprising a lifting means (285) having one or more transparent upper lifting members (260) for lifting the work piece (270) and a lighting means (230) positioned below the transparent members and rotatably coupled to the lifting means (285) by a rotating means. The lighting means rotatably extends when the lifting means (285) is raised, thereby providing illumination to the work piece (270), and rotatably retracts when the lifting means (285) is lowered.

Abstract: An apparatus to display images with partitionable regions allowing visible, invisible, and narrow field of view of displayed information includes a polarizing means to form a plane polarized light background from incident light, a liquid crystal panel capable of forming cross-polarized images against a plane polarized background, and a proximal movable polarizing means to distinguish images on liquid crystal panel from its plane polarized background. Linear translation of the movable polarizer partitions the liquid crystal panel into regions that are visible where there is optical alignment of the liquid crystal panel, background polarizer, and movable cross-polarizer. An optional remote polarizer complements the movable polarizer and provides a narrow viewing angle of images not visible on the liquid crystal panel.

Abstract: An optically readable matrix (100) has four intersecting sides of approximately equal length defining a perimeter and includes a binary code formed from light and dark squares of substantially equal sizes located within the perimeter. The matrix (100) comprises first and second orientation squares (105, 110) included in the light and dark squares and located in opposite corners of the matrix (100). Each of the orientation squares (105, 110) preferably includes a contrasting circular area (115, 120) located in a predetermined position within the orientation square (105, 110) and having a predetermined size relationship with the orientation square (105, 110). Such a matrix (100) may be formed on a printed circuit board (505) for use in an electronic device (500) to convey information about the printed circuit board (505). An apparatus (600) for decoding the matrix (100) includes an optical scanner (610) for scanning the matrix (100) and for locating the orientation squares (105, 110).

Abstract: A housing assembly (100) for enclosing a battery (108) and electrical circuitry (107) comprises a housing element (105) formed to enclose the battery (108) and the electrical circuitry (107) and a battery door (110) for providing access to the battery (108) enclosed by the housing element (105), wherein the battery door (110) comprises mounting means (115) for pivotally mounting the battery door (110) to the housing element (105) such that the battery door (110) rotates between an open and a closed position. The housing assembly (100) further comprises a conductive element (125) mounted to the battery door (110) for engaging the housing element (105) to secure the battery door (110) in the closed position, wherein the conductive element (125) electrically contacts the battery (108) and the electrical circuitry (107) to provide battery power to the electrical circuitry (107) when the battery door (110) is in the closed position.

Abstract: An apparatus (10) for visually aligning parts (13) for placement using one camera (18) comprises a device (12) for picking and placing a part on an object (15), a device (24, 26 & 28) for moving and removing optics (30, 36, 38) into and out of a work envelope having the object, a device (18, 40, 42 & 44) for locating landmarks on the object within the work envelope, and a device for aligning the part with the landmark in the work envelope.

Abstract: In an apparatus for depositing flux onto a solder work surface, a chamber having a plurality of openings therein is heated by means of a U-shaped current conducting heating element within which the flux chamber resides. This heating element heats the flux within the chamber until it vaporizes and is forced from the chamber through the openings onto the solder work surface.

Abstract: An automated component placement device (100) includes an automated robotic transporter (108) that transports a component (106) into an illuminated area (104) on a translucent compliant surface (102) upon which components (104) are placed in a three dimensional orientation such that a silhouette of the components, leads, coplanar or non-coplanar are created on the translucent compliant surface (102) when the translucent compliant surface (102) is flexed. The position of silhouette of the component (106) is used to determine the orientation of the component held by the robotic transporter (108) to facilitate the placement of the component (106).

Abstract: An apparatus is described for the magnification of an information display on a selective call receiver. The apparatus comprises an optical lens system coupled in a manner which provides for its easy attachment and removal from the selective call receiver.

Abstract: A dispenser (100) for solder flux includes a first solder flux reservoir (110) with a dispensing tip (118) at one end thereof for dispensing solder flux (112) in response to a frictional pressure applied to the tip. A second solder flux reservoir (102) is also included having a dispensing channel (106) for dispensing solder flux (104) responsive to a pressure applied to the flux (104) within the second solder flux reservoir (102).

Abstract: A hollow tube (3) supports a spring (5) coaxially positioned within the tube (3) and free to rotate within it. The tube (3) has a longitudinal slot (4) through which components (2) threaded onto the coils of the spring (5) hang down. A motor 6 rotates the spring (5) causing the components, constrained by the slot (4), to move longitudinally along the slot (4). When they reach the end of the slot (4), they are orientated by the end of the spring (5), which has been suitably shaped, to the correct orientation to be presented for automatic mounting on a printed circuit board.
