US Patent:

6547146, Apr 15, 2003

Filed:

May 3, 2000

Appl. No.:

09/565058

Inventors:

Boonphet Meksavan - St. Charles IL
James C. Graves - Rolling Meadows IL
Roman J. Berka - Algonquin IL

Assignee:

iPilot, Inc. - Schaumburg IL

International Classification:

G06K 710

US Classification:

23546246, 23546249, 23547203

Abstract:

A barcode scanning system and method, and hand-held contact scanner are provided. The contact scanner includes a photoemitter, a photodetector, a screen, abutted against the photodetector, for limiting the amount of light reaching the photodetector, a lens placed in front of the screen a memory for storing data related to transitions detected in the reflected beam; an infrared (IR) transceiver for transmitting the stored data to a host, a processor programmed to allow the scanner to read a barcode when the scanner is moved over the barcode at a lineal speed between one inch/second and five inches/second, a first manually-operated switch for activating the photoemitter in order to read the barcode; and a second manually-operated switch for causing the data stored in the memory to be transmitted by the IR transceiver.

Appl. No.:

10/086265

Inventors:

James C. Graves - Lake Forest IL

Assignee:

Watts Regulator Co. - North Andover MA

International Classification:

G05D 2313

US Classification:

236 122

Abstract:

A mixing valve includes a manifold, a temperature-responsive device, a first by-pass mechanism, and a second by-pass mechanism. The manifold defines a cold fluid inlet, a hot fluid inlet, a fluid outlet in fluid communication with the cold fluid inlet and the hot fluid inlet, and a mixing chamber in fluid communication with the cold fluid inlet, the hot fluid inlet, and the fluid outlet. The temperature-responsive device is capable of regulating the relative volumes of flow from the fluid inlets to the mixing chamber. The first by-pass mechanism is responsive to the pressure of cold fluid flow in the manifold to allow cold fluid to flow between the cold fluid inlet and the fluid outlet. The second by-pass mechanism is associated with the temperature-responsive device and is responsive to a temperature in the manifold to allow cold fluid to flow between the cold fluid inlet and the fluid outlet.
