Appl. No.:

10/743339

Inventors:

Ronald Zver - Lake Zurich IL, US
Edward Smith - Trevor WI, US
Donald Charles - Wauconda IL, US

Assignee:

Siemens Building Technologies, Inc. - Buffalo Grove IL

International Classification:

H01H 33/59
H01H 47/00

US Classification:

307115

Abstract:

An arrangement that provides power to an electrical device includes an inverter, first and second switches, and a bypass controller. The first switch has open and closed positions, and is operable to connect the inverter to the electrical device when in the closed position. The second switch has open and closed positions, and is operable to connect a utility power line source to the electrical device when in the closed position. The bypass controller is operable to cause a transition sequence in which the first switch changes to the open position and the second switch changes to the closed position. The bypass controller is further operable to: cause continuous actuation of a first indicator when the first switch is closed; cause continuous actuation of a second indicator when the second switch is closed; and cause intermittent actuation of the second indicator during at least part of the transition sequence.

Appl. No.:

10/310459

Inventors:

Ronald Zver - Lake Zurich IL, US
Nicholas Fowler - Hawthorne Woods IL, US

International Classification:

G09G005/00

US Classification:

345/765000

Abstract:

The present invention generally relates to a network based graphical user interface allowing individuals at a facility such as a factory work to efficiently communicate problems at the facility in real time. The graphical user interface of is comprised of one or more icons, with each icon representing a work site in a facility. Using the icons, workers at a work site can quickly communicate problems about the work site. The present invention allows managers at the facility to use the same graphical interface to drill down and quickly obtain information about potential problems in the facility. The present invention also allows managers to predesignate departments or individuals to respond to different types of problems at a work site, so that when a worker at a work site identifies a problem, notifications may be sent out in real-time to the department or individuals that need to respond to the problem.

International Classification:

B08B 1502

US Classification:

454 61

Abstract:

A system for monitoring the operation of laboratory fume hoods includes a local area network for transferring data representing alarm conditions, and other special functions, to a building supervisory control system. The system has a calibrating capability which is adapted to build a database of the operating parameters of the fume hood which can be used to detect any degradation of the operation of the fume hood.
