  • Publication number: 20030014336
    Abstract: With respect to a current quarter of unreported revenue for certain Internet companies, by processes performed by a computer revenue to date is analytically determined and future revenue for the remaining quarter is statistically projected by modeling revenue based on “Internet metrics”. Actual revenue performance is obtained and one or more “Internet metrics” are measured for a given Internet company. Using the revenue and measured Internet metric data from prior quarters, a regression analysis is performed in order to generate multiple models that reflect the relationship between the Internet metrics and revenue. From these models, one is selected that will most likely yield the best revenue estimates. This resultant model and current Internet metric data are subsequently used to estimate the company's revenue for the current day, week, month, or quarter. These estimates are also used to project the company's revenue for future days, weeks, months, and quarters.

  • Patent number: 6506098
    Abstract: A self-cleaning apparatus for use in a chemical mechanical polishing tool. The apparatus includes a slurry-dispensing arm with a first end suspended over a polishing pad, and a second end for mounting to the chemical mechanical polishing tool. A slurry-dispensing nozzle is positioned under the first end for dispensing a polishing slurry against the polishing pad. The first end has a compound slanted top surface, a front face and adjoining side surfaces. The compound slanted top surface forms a longitudinal peak slanting from center to both sides and from the back end to the front face. The top surface of the first end has a liquid distribution manifold that is mounted distally from the front face and has a plurality of nozzles directed to spray deionized water to wash away slurry splatter from surfaces of the first end of the slurry dispensing arm during the water polishing cycle.

  • Publication number: 20020189352
    Abstract: Disclosed is a MEMS sensor including a sense element and a single anchor that supports the sense element arranged in a central hub-like fashion that reduces the effects of thermal stress. Usually, two or more anchors are required to suitably constrain the sense element's motion. The anchor disclosed herein, however, supports the sense element with connection elements having a connection geometry that substantially limits the motion of the sense element to a single-degree-of-freedom. The connection elements may include, for example, converging flexures, an extender bar, or both.

  • Publication number: 20020194621
    Abstract: A consumer electronics device includes a universal control logic unit to interface a plurality of input controls, a display and an antenna to a host system via a bus. The host system is located within a shielded enclosure, while the remaining components (e.g., input controls, display, antenna, universal control logic) are located outside the shielded enclosure. Because a single bus preferably is used to interface the various input/output components located outside the shielded enclosure to the shielded host system, the host system can be more easily and effectively shielded than if numerous separate electrical lines and busses were used to directly connect the various input/output devices to the host system.

  • Publication number: 20020124883
    Abstract: A modular gas control device for use with a compressed gas cylinder (111) comprises a primary module (152) and a secondary module (252) mounted on the primary module. The primary module comprises a first supporting body (154) having a first main gas flow path (155) through the body. The supporting body has input connecting means (156) for mounting the body on the cylinder (111) and connecting the gas flow path (155) to communicate with the gas cylinder through a first flow path (157). Pressure reducing means (166) provides gas in the flow path at a lower pressure than in the container. Output connecting means (170) downstream of the pressure reducing means provides a low pressure outlet from the main gas flow path. A high pressure shut-off valve (164) is positioned upstream of the pressure reducing means, and filling means (161, 160) allows filling of the cylinder with compressed gas through the input connecting means (156) along a second flow path (159) separate from the input flow path (157).
