Communication system for the remote control of equipment (Hewlett-Packard): U.S. Patent No. 5,805,812

A communication system has a first computer, central controller and controlled equipment.

An operator may enter a desired performance by equipment on first computer which is placed in a communications packet with a device number, channel number, and one or more parameters and then sent to central controller for processing.
Central controller loads the parameters into memory and calls an appropriate function that uses the parameters to carry out the desired performance of the equipment.
The receipt and processing of the communication packet may be acknowledged by the central controller to computer.

Computerized shipment error proofing system and method (Hewlett-Packard): U.S. Patent No. 5,923,014

The invention includes a method for error proofing shipments where users are presented with the options of parts marking, parts verification or pack verification using an output device.

A user option choice is received using an input device. If the user chooses the parts making option, then a first part number is received from the user and causes the printing of a first quantity of labels in response to the first part number.
If the user chooses the parts verification option, then a second part number is received from the user, an identification symbol is scanned using a scanner to identify an identification number associated with the identification symbol, and the identification number is then compared to the second part number.
An indication is provided to the user if the identification number and second part number do not match. If the user chooses the pack verification option, then a third part number and quantity is received from the user.
Each of a plurality of identification symbols are scanned using the scanner to identify an identification number associated with each identification symbol. Each identification number is compared to the third part number and an indication is provided to the user if the identification number and third part number do not match.
A running total of the number of identification symbols having identification numbers matching the third part number is maintained.

System and method for device sequencing using discrete PLC control (Hewlett-Packard): U.S. Patent No. 6,897,675

A system and apparatus for discrete PLC control using word sequences in a data table for controlling a device on an assembly line.

The data table contains sequencing information which defines, for each station on the line, a series of operations with corresponding setup and operation parameters.
By placing the sequencing information in a data table, programming or changing the series of operations for a PLC is made much more simple and efficient.

Metal-Ligand and Process (Air Products and Chemicals): U.S. Patent Nos. 6,238,734 and 6,503,561“Liquid precursor mixtures for deposition of multi-component metal containing materials”

These patents cover a composition for deposition of a mixed metal or metal compound layer, comprising a solvent-less mixture of at least two metal-ligand complex precursors, wherein the mixture is liquid at ambient conditions and the ligands are the same and are selected from the group consisting of alkyls, alkoxides, halides, hydrides, amides, imides, azides cyclopentadienyls, carbonyls, and their fluorine, oxygen and nitrogen substituted analogs.

Low Dielectric Constant (Air Products and Chemicals): U.S. Patent Nos. 7,122,880, 7,294,585 and 7,482,676 “Compositions for preparing low dielectric materials”

These patents relate to a material suitable for use, for example, in electronic devices. More specifically, the invention relates to a composition for making a low dielectric performance material or film comprising 15 same having an improved elastic modulus and a low dielectric constant.

Equipment and Analytical Instrumentation (Air Products and Chemicals): U.S. Patent Nos. 6,639,214 and 6,686,594

Patent No. 6,639,214, “Method of improving the performance of an ion mobility spectrometer used to detect trace atmospheric impurities in gases,” is a method for eliminating interference when analyzing a test sample of a bulk inert gas in an ion mobility spectrometer is disclosed which includes the steps of providing an ionization source for the spectrometer to form ions of the bulk inert gas, mixing a reagent gas with the test sample prior to entry into the spectrometer to alter the nature of the ions formed by the bulk inert gas to shift the location of a bulk inert gas mobility peak such that a bulk inert gas mobility peak does not overlap with an impurity mobility peak of the ions of a trace impurity of interest, whereby bulk inert gas ions are quenched and a clusters of the reagent gas and the bulk gas are formed.

Patent No. 6,686,594, “An on-line halogen analyzer system and method of use for semiconductor processing effluent monitoring,” is a system that includes sampling the effluent stream into an absorption cell, and passing UV-Visible light through the effluent sample in the cell. After passing through the sample the light is collected by a photo detector for real-time wavelength-selective absorption analysis.
