Abstract: A readily reconfigureable cash dispensing system for providing change, such as coins of different values and bills or currency of different denominations needed by a retail store, grocery store, busy convenience store, or the like. A tray or trays for storing and delivering multiple rolls of coins or bills of a first value, as well as, a tray or trays for storing and delivering stacks of bills are described herein. A bill acceptor may be employed to accept bills used to purchase rolls of coins and stacks of bills, and a system controller can sense restocking and dispensing events to maintain an accurate inventory of cash in the bill acceptor, as well as, the total cash stored in the form of coin rolls or rolls bills, as well as, bill stacks.

Abstract: Novel methods are disclosed for designing and constructing miniature optical systems and devices employing light diffractive optical elements (DOEs) for modifying the size and shape of laser beams produced from a commercial-grade laser diodes, over an extended range hitherto unachievable using conventional techniques. The systems and devices of the present invention have uses in a wide range of applications, including laser scanning, optical-based information storage, medical and analytical instrumentation, and the like. In the illustrative embodiments, various techniques are disclosed for implementing the DOEs as holographic optical elements (HOEs), computer-generated holograms (CGHs), as well as other diffractive optical elements.

Abstract: Apparatus for deflecting a light beam, comprising: a scanning element having a base portion, a light beam deflecting portion, and a gap region disposed therebetween. The base portion is anchored with respect to an optical bench to permit the light beam deflecting portion to pivot about a fixed pivot point defined between the base portion and the gap region. The light beam deflecting portion has a natural resonant frequency of oscillation about the fixed pivot point and is mechanically-damped at the gap region. A permanent magnet and right beam deflating portion are mounted on the light beam deflecting portion. A magnetic-field producing coil produces a force field that interacts with the permanent magnet and forces the light beam deflecting portion to oscillate about the fixed pivot point at a controlled frequency of oscillation that is substantially different from the natural resonant frequency of oscillation of the light beam deflecting portion.

Abstract: A bar code symbol reading system is disclosed comprising a hand-supportable bar code symbol reading device which embodies an electronically-controlled bar code symbol reading engine for producing a raster-type laser scanning pattern in either a hands-free or hands-on mode of operation for scanning 1-D and 2D bar code symbols. The electronically-controlled bar code symbol reading engine has (i) a high-speed/high-resolution raster scanning mode of operation, during which a high-speed, high-resolution raster-type scanning pattern is precisely generated under electronic control, and (ii) a high-speed/low-resolution raster scanning mode of operation during which a high-speed, low-resolution raster-type scanning pattern is precisely generated under electronic control.

Abstract: A power supply enclosure device and method for suppressing the radiation of EMI from a power supply along power lines and for suppressing the entry of RF EMI into the power supply through the use of multiple tuned waveguides.

Abstract: A chassis divides vertically, with front and rear sections of the chassis joined immediately adjacent a midplane printed circuit board that supports interconnectivity of electronic circuits. Wiring within the chassis is eliminated through directed connections of all components to the midplane. Minimal hardware is required for securing the front and rear sections together, and therefore accessing the midplane for assembly and service is convenient. All components except the midplane are installed and removed from either the front or rear of the chassis without opening or disassembling the chassis. The chassis layout and features facilitate effective cooling of the components in the chassis.

Abstract: A flexible slotting system in a chassis easily accommodates printed circuit board assemblies having varying widths. A rib assembly is removably attached to the chassis frame to yield slots of the desired width. EMC gaskets over the entire length of the rib to prevent electromagnetic energy from leaking from the chassis.

Abstract: A self-aligning guide pin has two tapered protrusions. The protrusions seat in recesses in a printed circuit board to properly position and align the guide pin as it is mounted by a screw to the printed circuit board during assembly.

Abstract: A fan module includes a shell molded from plastic in a unitary construction. In the shell is mounted one or more fans, a printed circuit board assembly and a latching member.

Abstract: A surrogate card assembly is configured to mimic the profile of a printed circuit board. The surrogate card assembly takes the place of a printed circuit board in an array of boards in a chassis or housing and mimics the active printed circuit boards with respect to directing air flow and providing EMC shielding.

Abstract: Disclosed is laser beam scanning apparatus in the form of an electronically-controlled mechanically-damped off-resonant laser beam scanning mechanism. The scanning mechanism comprises an etched scanning element having a small flexible gap region of closely-controlled dimensions disposed between an anchored base portion and a laser beam deflecting portion The light beam deflecting portion supports a permanent magnet and a light beam deflecting element (e.g., mirror or hologram). A reversible magnetic force field producing device (e.g., an electromagnet) is placed in close proximity with the permanent magnet so that it may be forcibly driven into oscillation in response to electrical current flowing through the electromagnet. The resonant frequency of oscillation of the laser beam deflecting portion relative to the anchored base portion is determined by the closely controlled dimensions of the flexible gap region set during manufacture.
