    Currently, the holster used with the advisor pager bears a single clip mount (see Figure 1). FIG. 1 FIG. 3 Adding an additional clip mount on the opposite end of the holster gives the user an alternate way of removing his pager from the holster. If the wearer opts to use the reverse clip mount, he removes the pager...

    The current technique of ascertaining microcracks in packages comprises of penetrating dye into the pack- age. The dye is typically fluorescent under UV light. The package is decapped, typically by grinding, mechanic- ally removing or milling off the top or bottom half of the package. The dye traces identify the...

    A classical problem in integrated circuit design is controlling the slew rate of digital output signals. Signals that are too slow result in low operation speeds and signals which are too fast result in such effects as EMI noise and ringing of signals due to transmission line effects. Typical CMOS processes result in...

    In computer operation, a high speed intermediate cache memory enhances computation throughput. For example, on a RISC processor with a small on-chip pri- mary cache, a larger second level off-chip cache may be used. Cache memories may be used similarly with CISC processors. Instructions and data must flow to and from...

    SENSE cur Transistors Ql and Q2 shown in the above sche- matic are the output devices of an operational amplifier that is capable of a large dynamic output voltage swing. The function of the remaining circuitry is to accurately reproduce a fraction (l/N) of the amplier's output cur- rent (Iout) at the SENSE OUT...

    State-of-the-art RF Power Amplifier Modules used for portable communication transmitter applications use discrete, recessed gate, gallium arsenide (GaAs) MESFET devices for the driver and foal output stages as opposed to the silicon bipolar transistors used just a few years ago. Advantages of discrete recessed gate...

    For high speed bipolar and BiCMOS transistors, parasitic capacitances must be minimized. Base and col- lector side-walls add sign&ant capacitance to substrate. Reducing side-wall capacitances therefore improve tran- sistor speed and performance. In addition, new chip pack- ages require die front side contact to...

    This report describes a circuit technique for the design of Digital to Analog Converters (DACs) which provides an improved output voltage compliance for pre- cision DACs, typically those with 7-10 bits of resolution. The technique has been used for 7 and 8 bit DACs on a 3GHz bipolar process and produced untrimmed 11...

    The SOLDER STENCIL VACUUM CLEANING SYSTEM is a device used by a solder printing mecha- nism to clean its printing stencils. It utilizes a vacuum plus wiping tire to ensure cleaning of the solder sten- cils (Fire 1). The vacuum head is mounted on a self- leveling fixture to allow it to follow along the bottom of the...
