Nov 16, 2001

Appl. No.:

09/991770

Inventors:

John David Stanhope - Pflugerville TX
Joseph Albert Savage - Cedar Park TX
Gregory Clark Richardson - Round Rock TX

Assignee:

National Instruments Corporation - Austin TX

International Classification:

G06F 1300

US Classification:

713100, 713 1, 713 2, 714 26, 714 46, 714 47, 714 48

Abstract:

A system and method for deploying a hardware configuration with a computer program. The program may perform an instrumentation, measurement/control, industrial automation, or machine vision function, or other type of function utilizing hardware devices, and the behavior of the program may depend on various aspects of the hardware configuration of the computer system. An installation bundle that includes configuration information related to the hardware devices with which the program interacts may be automatically created and used to deploy the program on a new computer system. The installation bundle may include program instructions operable to install the program on the new computer system and automatically modify the hardware configuration of the new computer system so that the program will execute correctly.

Abstract:

System and method for using a graphical user interface (GUI) to generate a measurement task specification (MTS) for performing a measurement task. The measurement task includes measurement and/or signal generation. A measurement task specifier presents a GUI which guides a user in specifying the measurement task. The GUI presents a plurality of GUI elements, e. g. , panels, for specifying a plurality of parameters for the measurement task, including measurement type, devices, channels, timing, and/or triggering. The GUI receives user input indicating values for the parameters, and may provide default values for at least some of the parameters. The GUI stores the parameter values in a memory, analyzes the parameter values, and generates the MTS in response to the analyzing. The MTS is then useable to produce a program which implements the measurement task. The specifier may programmatically generate the program, e. g.

International Classification:

H05B 33/08
G01R 31/44

Abstract:

An illumination device and method is provided herein for controlling individual light emitting diodes (LEDs) in an LED illumination device, so that a desired luminous flux and a desired chromaticity of the device can be maintained over changes in drive current and temperature. According to one embodiment, the illumination device comprises a plurality of emission LEDs, a storage medium, an LED driver and receiver circuit and a control circuit. The storage medium may store a table of calibration values correlating forward voltage and drive current to chromaticity and luminous flux at a plurality of temperatures for each of the plurality of emission LEDs. The LED driver and receiver circuit may apply respective drive currents to the emission LEDs to produce substantially continuous illumination, and may periodically turn the emission LEDs off to measure operating forward voltages that develop across each emission LED. The control circuit may determine whether a target luminance setting or a target chromaticity setting for the illumination device has changed, and if so, may determine new respective drive currents needed to achieve the target luminance setting and the target chromaticity setting using the operating forward voltages measured across each emission LED, the table of calibration values and one or more interpolation techniques.
