• Re: Satellite P750: the fan rotates at high speed without load

  Hello
  I am a developer of software for the Germany and often uncomfortable in my quiet office. Well, since I got my new P750 I am facing a strange problem: while the CPU load remains very low, fan works suddenly 71% while the cpu temperature is 44% in health monitor. If I unplug the cable that the fan immediately gets quiet at 0%.

  for normal use with connected to the fan cable * always * works 64%, while having temperatures of 40%.

  I checked the settings in the power manager for the parameters of cooling system. If it is set for maximum performance on the cable and balanced on the battery, it seems completely unnecessary to let the fan run all the time, so only ist very low temperature.

  Hello

  As you probably know cooling fans are controlled by sensors on the motherboard and laptop users don t have much influence on the activity of the fan.

  In my opinion for your work you need high performance t n so I recommend you to use the power plan balanced all the time. In the balanced power plan change advanced power options > cooling method optimized battery and it should reduce the activity of fan.

  It is the same on my Satellite P500 and the laptop runs pretty quiet. Also, make sure that the laptop is placed on the desktop and noting may block the ventilation openings.

• back of the motor to the position in which he started?

  Hello

  I am writing an application to control a servo AC motor. It is based on reviews of couple. I use a state machine architecture. The result I'm aiming is,

  (1) the engine operating at a user specified speed and accel/break.

  (2) every time that the couple toggles between the upper and lower, limits the motor direction of rotation is changed.

  (3) at the end (the user specifies no. sometimes he should make this bike) the engine returns to the first zero position in which he started.

  (4) generates the data to the file and stops execution of the program.

  (1) and (2) have been supported. However, I'm still struggling with (3) and (4).

  What I have tried is to take note of the position of the encoder at the beginning of the program, and then after n cycles subtract aware of the position of him and give it as an input in State "Reset postion. Another thing I thought is playing with the tension (the departure of couple cell output voltage is always + 5V) so I thought to call the State "Motor Run" again at the end to move the engine to the original position. I tried some trial and error but am fultile in the efforts.

  No matter who may be likely to help the hand?

  Thank you

  Amandine.

  Hi Sasi,

  in case you have not found your bug by yourself, yet:

  After your state machine has entered the State of the 'RESET' POSITION you start a movement on the 0 position but you should not expect that the move is completed (this should be an additional State). Instead you immediately plug in "STOP ENGINE" and it stops moving without going back to the initial position.

  In addition, there are several things in your code that could be optimized (some examples):

  • By comparing a Boolean value as your STOP button with a constant TRUE is pointless, because the output is always the value of the STOP button. It's sort of a code of Rube Goldberg.
  • Your initialization state runs the same sequence of commands (displacement engine position 0) until button is pressed. There is a large number of redundant orders, sent to the Commission of control of movement.

  Kind regards

• HP Pavilion DV6: at startup BIOS showing CPU fan has stopped working, but I checked the fan is in good condition

  Hello

  I bought my HP Pavilion dv6 laptop 2011 as it starts a is overheating, freezing windows with noisy fan sound etc... but now, on information in BIOS boot indicating that the CPU fan has stopped working so immediately, I checked that I couldn't hear any noise from fan and no symptoms as fan works so I disassembled my laptop and removed CPU cooler fan only. Simply with the help of the battery, I checked the CPU fan it is running perfectly alone. but it does not work with the laptop.

  Note: Alsoft ships DW on a bootable DVD that will boot Mac running Snow Leopard or earlier. He cannot start Mac that came with Lion or later preinstalled, however, DW will work on these models.

  Suggestions for OS X maintenance

  OS X performs certain maintenance functions that are supposed to take place on a daily, weekly, or monthly period. Maintenance scripts that are run at the beginning AM only if the computer is turned on 24/7 (no sleep). If this isn't the case, then a great solution is to download and install a shareware like Macaroni, JAW PseudoAnacronor Anacron utility that will automate the maintenance regardless of whether activity if the computer is off or asleep.  Dependence on third-party utilities to run periodic maintenance scripts has been significantly reduced since Tiger.  These utilities have little or no functionality with Snow Leopard or later version, and must not be installed.

  OS X automatically defrags files smaller than 20 MB in size, so unless you have a disk full of very large files it little need to defragment the hard drive.

  Under no circumstances should you install operating MacPaw or ZeoBit software (CleanMyMac/CleanMyDrive or Mac Keeper, respectively.) You don't need special software to keep your computer.

  The following comes from user stevejobsfan0123. I made minor changes to adapt to this presentation.

  Difficulty a few pop ups browser that supported Safari

  Common pop - ups include a message saying that the Government has taken over your computer and you pay release (often called "Moneypak"), or a false message saying that your computer has been infected and you need to call a number of tech support (sometimes claiming to be Apple) to get it to be resolved. First of all, understand that these pop-ups are not caused by a virus and that your computer has not been assigned. This "hack" is limited to your web browser. Also understand that these messages are scams, so don't pay not money, call number, or provide personal information. This article will give an overview of the solution to remove the pop-up window.

  Quit Safari

  Usually, these pop-ups will not go by clicking 'OK' or 'Cancel '. In addition, several menus in the menu bar may become disabled and show in grey, including the option to leave Safari. You'll probably force quit Safari. To do this, press command + option + ESC, select Safari, press on force quit.

  Relaunch Safari

  If you restart Safari, the page will reopen. To avoid this, hold the "Shift" key when opening Safari. This will prevent windows since the last time that Safari was running since the reopening.

  It will not work in all cases. The SHIFT key must be maintained at the right time, and in some cases, even if done correctly, the window is displayed again. In these circumstances, after force quit Safari, turn off Wi - Fi or disconnect Ethernet, depending on how you connect to the Internet. Then restart Safari normally. He'll try to reload the malicious Web page, but without a connection, it will not be able to. Leave this page by entering a different URL, i.e. www.apple.com and try to load it. Now you can reconnect to the Internet and the page that you entered is displayed rather than the malicious.

  An excellent link to read is Tom Reed Mac Guide of malicious programs.

  Also, visit the FAQ XLab and read of detection and avoid malicious software and spyware.

  If you need antivirus protection Thomas Reed recommends to use ClamXAV. (Thanks to Thomas Reed to this recommendation.)

  The user Joe Bailey comes this equally useful advice:

  The facts are:

  1. There is no anti-malware software can detect 100% of malware out there.

  2. There is no anti-malware that can detect all targeting the Mac.

  3. the best way to prevent breaches the most is for you as the user is aware that

  the most successful malware attacks rely on sophisticated social engineering

  techniques preying on human greed, * and fear.

  4 Internet pop-up windows telling the FBI, NSA, Microsoft, your ISP has detected malware on

  your computer is designed to trick you into installing their malware thinking it's a

  protection against malware.

  5. some of the anti-malware market products are worse than malware

  go where they are supposed to protect you.

  6. be careful where you go on the internet.

  7. don't download anything from sites, you know are safe.

  8 avoid links that you receive in email, always be wary, even if you get something

  you think a friend is, but that you did not expect.

  9. If there is any question in your mind, then assume that it is malware.

  Troubleshooting Applications

  I recommend that you download a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaneror hiding a Cocktail that you can use to delete the former newspapers and archives, cleaning, etc. Corrupted cache, logs or temporary files can slow down the application or OS X crashes and panics of the kernel.

  If you have leopard snow or leopard, then for similar repairs install Applejackfreeware utility.  If you do not start in OS X, you can boot into single-user mode , where you can run Applejack to make a set of routines for repair and maintenance of the command line.  Note that it takes 1.5 AppleJack for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later versions.

  Basic backup

  For some people, Time Machine will be more than enough. Time Machine is part of Mac OS X. There are two components:

  1. a panel of Time Machine preferences as part of the system of preferences;

  2. a request for Time Machine, located in the Applications folder. It's

  used to manage backups and restore backups. Time Machine

  requires a backup drive that is at least twice the capacity of the

  drive being backed up.

  You can also get an external drive at least equal to the size hard disk internal and make (and maintain) a bootable clone/backup. You can make a bootable clone using the disk utility's restore option. You can also create and maintain clones with good backup software. My personal recommendations are (the order is not significant):

  1 Carbon Copy clone

  2. get backup

  3 already seen

  4 superDuper!

  5. Synk Pro

  6. Tri-Backup

  Visit The FAQ XLab and read the FAQ on the backup and restore.  Also read How to back up and restore your files. For using Time Machine, visit FAQ Time Machine of Pondini for help with all this time Machine.

  Referenced software can be found at MacUpdate .

  Additional tips

  Make sure you have a sufficient amount of RAM installed for the number of applications you run simultaneously. Make sure to leave a minimum of 10% of the capacity of the hard disk as free space.

  Add more RAM. If your computer less than 2 GB of RAM and you use OS X Leopard or later, then you can do it with more RAM. Snow Leopard and Lion works much better with 4 GB of RAM that is their system. Most concurrent applications, that you tend to use the more RAM you should have.

  Always have at least 15 GB, or 10% of the capacity of your hard disk as free space, the largest. OS X frequently accesses your hard disk, so offering enough free space will keep things slow down.

  Check for applications that may be hogging the CPU:

  Before Mavericks

  Open the activity monitor in the Utilities folder.  Select all processes in the drop process .  Click the % CPU column heading twice to display in descending order.  If find you a process that uses a large amount of time processor (> = 70,) then select the process, and then click the quit icon in the toolbar.  Click the force quit button to kill the process.  See if that helps.  Don't forget to mention the name of the runaway process, so you can find the cause of the problem.

  This problem occurs often because of a corrupted cache or the preferences file or an attempt to write in a corrupted log file.

• Problem - edges of digital triggering slows down during the fast rotations

  Hi all. I have problem to understand. I want to measure the pressure with two strain gages on 90 degrees (NI 9237 half bridge II) and I engine with metal plate on it with 52 teeth (gear) to measure on each tooth of the strain. For the rotation, I use NI 9401 digital input.

  I need for example 1000 samples from the first digital edge to the second. (on the metal plate). I try to start trigger. In slow speed (turn around with the hand) of the metal plate, everything is OK. But if I turn around the metal plate digital fast triggers edges slows down. During a cycle on the metal plate on the cost of slow speed me 52 digital edges 1000 sampels by edge (metal plate is with 52 teeth), but rely on fast speed on me 25 edges. This problem is sync of the digital inputs and the analog inputs. I made the example with DAqmx Vi express. I've implemented on digital imput and then count me in each tooth regardless of speed and everything is OK, but when I buid trigger of strain on the edges of quick release rotation speed slows down.

  Can someone help me with this?

  Thanks before.

  So you're collecting samples from 1000 to 10000 samples per second. Which takes 100 Ms. If your triggering edges occur more quickly than the interval of 100 ms, some of them will be missed.  If you run faster than a cycle all 5.2 seconds your gear plate with 52 teeth, some triggers will be produced before the end of the previous data collection.

  What is the fastest speed that you will not sping palte metal?

• Check the development of an Image with Standard of LABVIEW functions

  Hello

  I want to determine the best quality of the development of a series of color images using features standard LABVIEW, an example my images would be KING of coins in copper or similar sample 2 mm x 1 mm. I do not have the Toolbox IMAQ vision, so this will not be an option. Could someone give me an example of this or point me in the direction I must go. Is it better to check the quality of the focus on the image of color or black and white image or perhaps a representation of the intensity of the image? I heard that the gap checking type of a line of pixels in the image would give a good indication of the quality of the development by seeking the higher SD all images?

  Any help is greatly appreciated!

  Convert the image into an array to IMAQ ImageToArray.

  Extract a single line or row of the table by using the table to Index.  Assuming that your image be U8, these will be U8 values.

  Digital conversion to Double can convert the array of double values.

  Use Rotate 1-d array with an offset of 1 to turn the table.

  Subtract the table of rotation of the rotation matrix.

  Deletion of the table to delete the first element of the array.  It's the difference between the first and last items, which is not desired.

  Absolute value to convert the table of all positive values.

  Use the mean or the standard deviation to measure the development.  I usually have better results with the standard deviation, but sometimes means gives good results also.

• How to use Labview to control the motorized turntable?

  Hello

  I am new to Labview and do a project that requires the use of labview to control the motorized turntable (XYZ axes). I need to use the Labview programming and have no idea at all. Need help, thank you very much!

  Lei,

  Everything said by others is correct and to do because they describe, at a given time. But I always approached these projects of motion control first by looking at the 'motion controller' (I hope you have a) and 'drivers' (what you need) between the computer/LabVIEW and engines decide what communications will be required for these devices and get an idea of the syntax of command and the language to use with them.  In some cases, the controller and the motor driver are integrated in a single unit. Heck, in some cases, they are even integrated with each engine.

  The motors can be the stepper motors or perhaps servomotors.

  In the case of drivers stepper (devices that provide power electronics to run the engines), many of them are run using only two control signals for digital called 'step' (a pulse train) and 'direction' (high-low level) and if it is possible to generate directly with the PC, it's an order of magnitude easier (if you have not already a library of available motion control to manage the generation of these signals and) the execution of the stepper motors) of having a "Motion Controller" between the PC and the "motor".  Engine drivers step by step usually can be configured that current engine and the size of the stage and sometimes for the other plus-moteur/driver-parameter setting. The configuration of these can be made with jumpers, switches or, for some drivers, with orders ASCII on some sort of port of communication, but in general these are values you download the installer once at the beginning and then never touch again if you do not need generally to have a full time available on their change communication path.

  In the case of the actuator drivers (once again the devices that provide power electronics to run the engines), many use a +/-10V control input analog signal, and, again, while it is possible to generate the signal directly with the PC hardware, a separate axes controller is usually much simpler and more robust.  In the case of a servo system, there is also a signal back to an encoder or resolver attached to the engine to be used by any device will exercise the motion controller in the system.  There are once again associated with the driver configuration parameters (and controller in this case, since it is part of the servo feedback loop) which must be configured at the start but once set up properly, they rarely need to be changed again.

  A movement controller which is separated from the PC often manage several drivers, and can often coordinate a movement between them. It will load the rise up/down of the engine speed as that changes. It will be followed by position of each motor. The servo system, but it will take the feedback signal and use it to adjust the speed/position/torque of the engine. The motion controller also deal with race and home or index of signals is usually on most lines of movement and provide information of the State of the switch to the PC.   To run the motor controller is then just a matter of chaining a set commands of (usually ASCII) to indicate how fast to run and how far to go (and direction) and by sending a command "do it." Then, ask you to keep track of the status of the process and the States of the switches.

  In many cases the builders of controllers of movement are a primitive way to communicate with the controllers of a PC with no additional software other than what they offer. With this you can at least have an idea of how different the controller commands and responses they produce. That you can start to build sequences of commands to perform the actions you want.

  You can then add LabVIEW to the mix and to understand how you can get it to send sequences of similar orders on the paths of communication that are available and respond intelligently to the information it receives in return for motion control.

  I'm not sure what a certificate of authenticity of the situation - I think nothing.  What you need is a product key (an alphanumeric code of 25 digits in 5 groups of 5 digits separated by dashes), usually affixed to the botton, back, or on the sides of the computer - unless you are fairly well watered and the disc will be useless since you will not be able to activate.  As well as the product key you need an Installation of Vista genuine disc (any disk of the same size of the ILO will be - maybe you know someone you can borrow an of) or an OEM Installation disc or a recovery disc from the manufacturer (at a small fee) or maybe there is a Partition of Recvery (depending on the manufacturer and the make and model of computer) - you can ask when you contact the manufactrer and their ask how to access - it will be a keyboard command any (not a BIOS change) assuming that it was not erased when they cleaned the disc.

  There is no download legal, free to a Vista installation disc, and you cannot use the recovery disk from another computer, because pilots and other information will be wrong and it will mess up of the facility and maybe even cause damage.

  Here is the Microsoft policy about lost or missing software: http://support.microsoft.com/kb/326246.

  I hope this helps (or at least, clarifies the situation).

  Good luck!
