US Patent:

6396484, May 28, 2002

Filed:

Sep 29, 1999

Appl. No.:

09/408818

Inventors:

Robert Adler - Northbrook IL
Arie Ravid - Newark CA
Geoffrey D. Wilson - Oxnard CA

Assignee:

Elo Touchsystems, Inc. - Fremont CA

International Classification:

G09G 500

US Classification:

345177, 345173, 345176

Abstract:

A method and apparatus for adapting an acoustic touchscreen controller to the operating frequency requirements of a specific touchscreen are provided. The adaptive controller can either utilize look-up tables to achieve the desired output frequency or the it can use a multi-step process in which it first determines the frequency requirements of the touchscreen, and then adjusts the burst frequency characteristics, the receiver circuit center frequency, or both in accordance with the touchscreen requirements. In one embodiment, the adaptive controller compensates for global frequency mismatch errors. In this embodiment a digital multiplier is used to modify the output of a crystal reference oscillator. The reference oscillator output is used to control the frequency of the signal from the receiving transducers and/or to generate the desired frequency of the tone burst sent to the transmitting transducers. In another embodiment that is intended to compensate for both global and local frequency variations, the adaptive controller uses a digital signal processor.

US Classification:

705/038000, 705/035000

Abstract:

An exemplary embodiment of the invention is a method for providing online commerce. The method includes receiving a request for credit functionality from a customer and establishing credit account if the customer meets credit worthiness requirements of a credit provider. An account identifier is associated with the credit account. The method also includes receiving a request for debit functionality that includes debit source information. The debit worthiness of the debit source is verified and the account identifier is associated with the debit source.

Appl. No.:

8/485351

Inventors:

Geoffrey Robert Wilson - Pittsburgh PA
Norman L. Carr - Wexford PA

Assignee:

Wexford P.A. Syncrude Limited Partnership - Pittsburgh PA

International Classification:

B01J 2300
C07C 2700

US Classification:

518714

Abstract:

A catalyst and slurry reactor Fischer-Tropsch conversion process utilizing novel catalysts comprising cobalt promoted with molybdenum or molybdenum and zirconium on a small diameter inorganic oxide support. The catalysts have been found to be highly selective for production of liquid hydrocarbons while minimizing production of less desirable oxygen-containing products such as alcohols. The preferred catalysts contain from about 5% to 50% cobalt and from about 0. 1% to 10% molybdenum or molybdenum and zirconium.

Gulf Research & Development Company - Pittsburgh PA

International Classification:

C07C 510

US Classification:

260667

Abstract:

Aromatic hydrocarbons are hydrogenated in the presence of hydrogen and a catalyst composite comprising at least two hydrogenating agents and an alumina support having a controlled bayerite concentration, average pore radius, and pore volume distribution and further having been calcined at a temperature in the range of 800. degree. - 1600. degree. F. (427. degree. - 871. degree. C. ) prior to impregnation of the hydrogenating agent.
