Method And Device For High Speed Scale Conversion

US Patent:
6446102, Sep 3, 2002
Filed:
May 21, 1999
Appl. No.:
09/316892
Inventors:
David L. Kryger - Chelmsford MA
Steven Webster - Raymond NH
Assignee:
Schneider Automation, Inc. - North Andover MA
International Classification:
G06F 501
US Classification:
708208, 341 96
Abstract:
A method and a device for high-speed scale conversion wherein a value N within a range of N1 and N2 is converted into a small value M within a range of M1 and M2. The method includes the step of obtaining an approximate value of M by loading the value (N-N1+2 ) into a multi-bit shift register and right-shifting p bits. A binary search process is then used to determine the error value between the actual value of M and the approximate value of M. By avoiding actual multiplication processes, the conversion can be carried out using low-cost electronic hardware such as a microprocessor or a PROM to carry out the binary search process, a shift-register to obtain the approximate value of M, a multiplexer to receive an analog input data N and an A/D converter to convert the analog input data N into a digital data N.

Method And Apparatus For An Active Standby Control System On A Network

US Patent:
6968242, Nov 22, 2005
Filed:
Nov 7, 2000
Appl. No.:
09/707604
Inventors:
Nan Shan Hwu - Carlisle MA, US
Jay Ward - Stratham NH, US
David L. Kryger - Chelmsford MA, US
Assignee:
Schneider Automation Inc. - North Andover MA
International Classification:
G05B009/02
US Classification:
700 82, 714 4, 714 11
Abstract:
A method and apparatus for providing an active standby control system comprising the steps of providing a first and second controller, each controller having an operating state. Each controller is operably connected to a network. Assigning a network identifier, i. e. , Internet Protocol, Media Access Control address, etc. , to each controller and sensing the operating state of each controller. The network identifier of each controller is determined by the operating state of each respective controller.

Mask Analysis

US Patent:
4218142, Aug 19, 1980
Filed:
Mar 8, 1978
Appl. No.:
5/884606
Inventors:
David L. Kryger - Chelmsford MA
R. William Killam - Tewksbury MA
Assignee:
Aerodyne Research, Inc. - Bedford MA
International Classification:
G01N 2132
US Classification:
356394
Abstract:
Masks used in the production of integrated circuits are analyzed and tested by a scanning spot from a laser beam comparing the position signal of the scan from a mask against a data base representing another mask which may be selected at random. Apparatus includes a laser, means to form and scan a minute spot from said laser, an x-y stage to move a mask under the scan, a detector, and means to compare scan results.
