Frequently Asked Questions

Can the DS3 Light Grids measure objects with a 0.5 mm precision?

DataSensor Sensors FAQs Infra Photoelectric Area Color Laser...
No, the objects can only be detected in the crossed-beam scanning, the measurement can be made only in the parallel beam mode.

What is the difference between the absolute and relative measurement in DS3 light grids?

DataSensor Sensors FAQs Infra Photoelectric Area Color Laser...
The absolute measurement provides a voltage signal proportional to the last optic interrupted and can be useful, for example, with objects presenting holes or openings. The relative measurement provides a signal proportional to the number of optics interrupted, and so the object width.

What is the difference between the relative and absolute detection in DS3 light grids?

DataSensor Sensors FAQs Infra Photoelectric Area Color Laser...
In the first mode the object can be detected in any position inside the measurement field. In the second mode, in one pre-established position. These modes can thus solve many different applications, ranging from presence and orientation control, object identification as well as guide control.

Can objects move away from us faster than the speed of light?

Frequently Asked Questions in Cosmology
Again, this is a question that depends on which of the many distance definitions one uses. However, if we assume that the distance of an object at time t is the distance from our position at time t to the object's position at time t measured by a set of observers moving with the expansion of the Universe, and all making their observations when they see the Universe as having age t, then the velocity (change in D per change in t) can definitely be larger than the speed of light.

Will I be able to reduce the width of the hider lip from 0.5 mm?

FAQs - 3M(TM) Acrylic Plus Tapes US automotive auto autos au...
Hider lips are generally added for styling and cosmetic purposes. Because our 3M Acrylic Plus Tapes are black and provide a tighter bond line than conventional 3M AFTs (stress distribution), the tapes should provide for reduced or eliminated hider lips. It's part of our overall system cost advantage to providing a sleeker product.

Can one measure low magnitude residual stresses with good precision?

Slitting: FAQ
Definitely, that is one of the strengths of slitting measurements. See the measurement results in the stress relieved aluminum for a good example. There the stress magnitudes are under 20 MPa (3 ksi, σ/E < 0.0003) and the uncertainty was about ± 1-2 MPa. See also the paper by Aydiner at al. (reference) where the stress magnitudes in a bulk metallic glass were less than 15 MPa (2 ksi , σ/E < 0.0002) and the uncertainty was about ± 1-2 MPa. Back to top

What Are Grids?

Answers for your questions.
Grids are decorative bars that are inserted between the panes of glass to resemble a window that has been divided into smaller lites. They are available in multiple styles and configurations. Grids are cosmetic only and are not a factor in the operation or performance of the window. See an example of grids. In some brands, a cosmetic grid is applied to the exterior giving a more divided lite appearance.

How do I measure a Xennon or flashing light?

Frequently asked questions
With a camera, when you take a flash photo, the shutter opens at a fixed (typically 1/60 sec) speed, then the flash is triggered electronically a few milliseconds later. The flash is over in a less than 1 mS, then the shutter closes. If the picture is over exposed, one can only reduce the f-stop (according to a table e.g. on the flash unit), or reduce the 'guide number' of the flash unit, or by moving further away.

Can you measure the hardness of our 0.8 mm diameter wire?

Material Testing - Frequently Asked Questions, FAQ, TCR Engi...
We can measure Vicker's Hardness by MICRO VICKERS HARDNES TESTER with 50 or 100 gm load after mounting the specimen in Plastic Mould. The charges per sample will be Rs. 400/- plus 12.24 Service Tax and we will report hardness by 3 indentations. Please mark the location where hardness is needed. Mechanical Strength means one of several tests including Impact, Hardness, Compression, Fatigue, and more.

After I turn on lighting, everything is lit. How can I light only some of the objects?

OpenGL FAQ / 18 Lights and Shadows
Remember that OpenGL is a state machine. You'll need to do something like this: glEnable(GL_LIGHTING); // Render lit geometry. glDisable(GL_LIGHTING); // Render non-lit geometry.

Q - What are subdural grids?

The California Pacific Epilepsy Program
A - A subdural grid is an array of up to 64 contact points from which we can record the brain's electrical activity. It is placed on the surface of the brain through a craniotomy incision. The grid can also be used to map out speech and motor areas to help guide the surgeon in the resection. A circle of skull (craniotomy) is temporarily removed in order to place grid electrodes.

OK, so how do you measure the quality of light?

Energy Efficient Lighting FAQ
Colour (Correlated Colour Temperature - CCT), measured in Kelvin (K). This varies from the warm tones of a candle, at about 2200K to the cool-blue light of the northern sky, at about 9500K (somewhat counter intuitively, the "cooler" colours have a higher K number). Colour Rendering, or how true-to-life does the colour of lit objects appear. This is measured by the Colour Rendering Index (CRI), which varies from 0 to 100.

How can I move objects within my Forest?

Environment settings set by a batch file are not working.
The Windows 2000 Resource Kit ships with the MOVETREE.EXE utility which can be used to move organization units, users or computers between domains in a single forest. This is useful for the consolidation of domains or to reflect organization restructuring.

What are Tombstone objects?

Environment settings set by a batch file are not working.
Because of the complex replication available in Windows 2000 and the Active Directory just deleting an object would result in it potentially being recreated at the next replication interval and so deleted objects are 'Tombstoned' instead. This basically marks them as deleted and applies to all objects.

Some objects are slower?

Frequently Asked Questions (FAQ)
Install DirectX 7 (or later) and just click "Ok" when it looks for dx61eng.exe in the default directory and then click "No" when it asks if you would like to try another directory during the Art-o-matic install to ignore that prompt. Position the mouse over anything and press F1 key. Position the mouse over a menu item, button, check item, slider, window, object, ... anything! Then read the message at bottom of screen.

WHAT IS MM?? OR TT??

Hallmark Frequently Asked Questions
MM is the common abbreviation for Merry Miniatures. The popular line of small mini resin/plastic figurines available at most Hallmark stores. As of 1996 Hallmark will be issuing them as boxed sets although some stores will still offer them individually. TT is a common abbreviation for Tender Touches. This was a Gallery Line Hallmark recently retired. The figurines/sculptures were done by Hallmark artist, Ed Seale and were/are really popular.

How do I measure light sources with a high proportion of visible?

Frequently asked questions
When measuring a light source with a very high proportion of visible present, a filter will be required to reduce or exclude the un-measurable light. Solatell are able to supply 2 different filters (DUG11 and UG5) which filter a specified wavelength range, especially UVC and visible wavelengths. The purpose of this filter is to decrease the stray lights and obtain a more accurate measurement in the unfiltered region.

Q] What is the problem with memories and DS3?

Gigabyte DS3 FAQ - Overclock.net - Overclocking.net
A] Some memories require 2.0V to boot. Standard DS3 stock VDimm is 1.8V. Simply after a CMOS reset the system won't boot... If you happened to have such mem, replace them. Or buy some shi++y lowcost mem and put it in to boot, change VDimm and replace with your modules to continue o/c.
