HCPL0631 does not work properly please help!
To s Adminitrator.
I try to use the HCPL0631 optocoupler for my simulation. However, this optocoupler may not work properly and will not give me a good result.
I am attaching the wiring in the attachment diagram, please let me know what the problem with my circuit causing components to fail.
Thank you for your kind attention
Actually, nevermind, the model for the HCPL0631 is not very good. It's not real have an open collector output. He also built in 5V VDC, so power that you are joining is not really used. Your problem is grounded. Constructions of Multisim Power equations and node for the simulation of mesh and can not do it with precision if you do not specify the field for your tour.
Try to add a pattern to the GND of the optoisolators Terminal. You must also have a ground attached to the cathode of the optoisolators or the neutral wire from the unit. The LAND component is the database in the Group of Sources and the family of the POWER_SOURCES.

Lightroom to photoshop panorama does not work properly please help!
I do an online tutorial about editing a series of way milky way photos in lightroom and their fusion in a panorama in photoshop. I followed the instructions exactly as they are in the video, with the same settings, but when my panorama created layers (?) are not properly mixed. I don't know what I am doing wrong, or how to solve this problem, since I am quite new to photoshop!
I have synced settings in lightroom, choose "change in" and then "merge to panorama" in photoshop. Once it has opened in photoshop, I left the settings on 'Auto' and 'mix images ".
I hope someone can help. So I'm back on this whole photoshop thing and end up still very confused!
The Photomerge in Photoshop script, which is what you are citing here, can be divided into its essential components - Edit > Auto align first, then Auto Blend. Try this just to check if the basic features are there.
For this you need to have files stacked like layers in Photoshop and all selected layers. Put the central image at the bottom of the stack, it's the other alignment to.
It could be this mixture does not work because you don't have enough overlap from real image data. Yes, there is much overlap in the area here, but white spots on a monochrome background may not be enough, especially if the noise starts to compete with the stars, or the stars are slightly out of alignment. So try another game also.

E280 v2 - My MTP does not work. Please help me.
I got the Sansa since 11/07. I was wrong before, but this is the most frustrating problem to date. Two weeks ago the device quit afford toansfer audio books (via the Overdrive Media Console - WMA software - draws) from my laptop to the device. It gave me an error message in a form that I didn't understand.
I called the support people and a great man helped me to download the updated firmware. I added the function USB and the MSC option. I was able to transfer audio books. Once I started listening to a book, he let me only hear both sides and then I got a message that I had to synchronize to continue my subscription to media. I recalled the support of the people, and they said nothing was wrong with my camera.
I contacted the support of Overdrive. I was told that the books must be downloaded and played through the PSG because of the license. I tried to transfer under the PSG and now my computer does not recognize the device - so I cannot transfer books or even get an error message that the systemwill won't let me transfer books.
I looked and looked for a solution to the problem of the PSG. I am not computer savvy and Sandisk has more support on the weekend, so someone please, please help me. Thank you. CAL
After the second roll back to 10, I decided to uninstall it and download the WMP 10 from Microsoft.com. Once I did, my drive was recognized by the computer, but not as a portable device. I was able to transfer and play audio books, so it seems that my computer is now recognize the MTP driver.
I downloaded more books tonite and everything seems to work very well. Thank you all. CAL

my SQL Developer does not work properly! Help
Hello!!
My problem here is not like I can't live or work, but it's REALLY annoying, see my SQL Developer does not take any different key of letters and the space bar, I mean, if I use the Enter key, does not alter the line, if I use the return key back isn't clear if I use F5/F9 does not execute the msec! and if the keys don't work!
any ideas why this is happening? and if yes how do fix this problem?There is a well known bug but still not solved, causing this type of behavior, if you are a developer SQL 1.5.X you can work around the problem by loading the accelerators by default:
Tools-> accelerators-> load Preset-> by default
If you're on 2.1.X preset may be responsible for
Tools-> preferences->-> others-> load keyboard accelerators
2.1 this problem has not been reported so far, so if you are in 1.5.X you can consider upgrading.

(Vista) computer does not start properly (Please HELP)
My guarded vista stop without known reason. He started up the main login screen and I could connect. After that so long it would just turn off. I did a system restore, system repair at startup and F8 pressed and is entered in safe mode. Now, I have a new problem. He worked for a few hours. Enough to do a bit of homework. Then suddenly it disconnects and begins to do the updates for windows. Then it goes to a black screen and tells me what he planned for a clean disk. So he goes through this process and restarts. Now it is impossible to get pass Part 3 of 3 updates and it just stays at 0%. He will remain on this page for about a minute and just keeps restarting itself. I tried F8 again and cannot get into safe mode. WHAT IS WRONG WITH MY COMPUTER HELP ME! (PS: now I use my laptop which is a XP!) Help, please!

Gradient in Photoshop CS4 will not work properly, please Help!
I just bought a new computer, it has windows 7 quad i7 processor (Q820 1.73 GHz with technology turbo boost to 3.06), operating system and 500 GB hard drive of 64 and 8 GB of Ram, card graph NVIDIA 1 G of Ram. I installed CS4 and when I try to use the gradient tool leading normal mode to transparent and apply it the first time, it seems to work, but when you submit a new application to adjust the angle or what it continues just fill the page and, eventually, the entire page is filled with the foreground color and transparency will disappear. I have unchecked the Open GL in preferences and increased the amount of RAM photoshop can use of 5185 and cache to 6 levels.
That I am I doing wrong and what else can I try? He has a problem with CS4 and there patches there. I looked in the forum and online and I have not really found something about it. The other gradients seem to work very well as long as you're not leading to transparency!
Someone else has this problem and what can I do about it?
I really appreciate your help
Correct behavior. A tool is a tool and a comits activities immediately to the content of a layer pixel. If you need the modified gradients, using gradient overlay layer styles.

I have a HP Pavilion zd7000 that bad on the hard drive. I bought another and used the reinstallation disc to reinstall Windows Home Edition. Everything seemed to go well, but it starts now to a HP Invent logo black screen that says press F10 to go together to the top and F12 at startup of Lan. Then, a second black screen appears that says press F1 to resume or F10 Setup. I press F1 and Windows loads very well. What can I do to have Windows load immediately without going through this? Any help will be greatly appreciated! Thank you much in advance!
