Appl. No.:

10/709351

Inventors:

Philip L. Campbell - Millbrook NY, US
Francis F. Szenher - Fishkill NY, US
Uldis A. Ziemins - Poughkeepsie NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04B 1/69
G06F 19/00

US Classification:

701 23, 375130

Abstract:

Communication between a controller and a set of automated vehicles is improved by use of an RF link that employs a high frequency spread spectrum modem that establishes a low noise link in a high noise industrial environment and also shares the relevant frequency range with a wireless telephone system.

International Classification:

H03L 7/06

US Classification:

327157, 327148

Abstract:

A method includes phase-shifting an output signal of a phase lock loop (PLL) circuit by applying an injection current to an output of a charge pump of a the PLL circuit. A circuit includes: a first phase lock loop (PLL) circuit and a second PLL circuit referenced to a same clock; a phase detector circuit that detects a phase difference between an output signal of the first PLL circuit and an output signal of the second PLL circuit; and an adjustable current source that applies an injection current to at least one of the first PLL circuit and the second PLL circuit based on an output of the phase detector circuit.

International Classification:

H01L023/02

US Classification:

257783000

Abstract:

An integrated circuit (IC) chip module includes at least one integrated circuit chip mounted upon a substrate, and a plurality of passive components mounted upon the substrate. A polymer based bib has at least one opening formed therein, the at least one opening configured to accommodate the at least one integrated circuit chip therein, and the bib further configured for attachment to one or more of the plurality of passive components. A protective cap is mounted over the at least one integrated circuit chip and attached to the substrate, wherein the bib is configured to retain thereon a thermally conductive paste initially applied to at least one of the integrated circuit chip and the protective cap.
