摘要:
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.

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).

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.
摘要:
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. By creating a user defined visible, invisible, and narrow field of view of displayed information on an LCD assembly, electronic devices incorporating such a display can be made to provide computing privacy, accessibility to the device, strategic information separation, and information separation to multiple users.

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.
摘要:
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). Determination circuitry (710) coupled to the scanner ( 610) determines the size and distance between the circular areas (115, 120) relays the information to computing circuitry (715), which computes the size, orientation, and density of the matrix (100). A controller (705) thereafter translates the binary code.
摘要:
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).
摘要:
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.
