What are the materials used for the earbuds/earphones?? Like whats the plastic used and what are the speaker materials and the volume button???

Hello Veronica176
The materials in Apple headphones include Neodymium magnets, oxygen-free electrolysis copper wire and a Nickel plated plug
Apple uses Neodymium magnets in their headphones as it is much more magnetic compared to that of a ferrite magnet. This also further enhances the accoustics of sound and preventing any loss of sound. Because of this, you can get the same sound out of Apple headphones as the good ol' circum-aural headphones (image attached).
Oxygen free copper wire is created through electrolysis which is furthermore considered an above average material for headphones, thus ensuring better sound quality. Oxygen free copper wire ensures a faster transfer time (as copper is one of the best conductors) and because of this, allows a faster transfer time, minimising loss. This means the sound quality of the music/sound playing may actually depend more on the quality of the MP3 file than the headphones.
The nickel plated plug used by Apple is a standard connection and joins to a female connection into the iPod (for example) which is also nickel plated. Where gold plated plugs are renowned to transfer more data and superior sound quality when connected to any device. Connecting the same metals during transfer (nickel plated plugs and nickel female connections) ensures optimum sound as the signal will not be jumping different kinds of metal. The lack of gold plating also helps to reduce the cost in manufacturing and to the customer.

  • Report to Generate Materials Used for the Production of FG/SFG Materiak

    Dear Experts,
    I am working for a Cement Factory. CLINKER is a SFG used for the production of FG Cement.
    RMOPCK1 and FINECOAL are another SFG used for the Production of CLINKER
    RMOPCK1
         +               = CLINKER + (Different Materials) = CEMENT
    FINECOAL
    For CLINKER we will create process order every month similarly for RMOPCK1 and FINECOAL.
    RMOPCK1 is using 5 Raw materials and FINECOAL is using 1 raw material
    Limestone + Silica 1 + Silica 2 + Bauxite 1+ Ironore 1 = RMOPCK1 and
    Rawcoal = FINECOAL
    All the raw materials, SFGs are used for creating different variety of cement.
    I want to know for a certain period how much is the CLINKER produced and How much is the raw materials used for producing the CLINKER.
    When i try through KOB1 with the process orders for CLINKER it is giving me total usage ofr RMOPCK1 and FINECOAL for producing the CLINKER.
    I Want to know for ex:
    the quantity of raw materials (Limestone + Silica 1 + Silica 2 + Bauxite 1+ Ironore 1 )used for producing ex: 1000 TON of CLINKER.
    Please help. Thanks

  • What are type defs used for?

    I am learning about type defs and wanted to ping the community to get a feel for what expanse of things they are useful for.  Any and all comments are welcome.
    Cheers!

    Using LV 2013, 2012
    Don't forget Kudos for Good Answers, and Mark a solution if your problem is solved.

    I found this (from LV Help) enlightening as to the differences between typedefs and strict typedefs:
    Type Definitions and Strict Type Definitions
    Use type definitions and strict type definitions to link all the instances of a custom control or indicator to a saved custom control or indicator file. You can make changes to all instances of the custom control or indicator by editing only the saved custom control or indicator file, which is valuable if you use the same custom control or indicator in several VIs.
    Type Definitions
    Type definitions identify the correct data type for each instance of a custom control or indicator. When the data type of a type definition changes, all instances of the type definition automatically update. In other words, the data type of the instances of the type definition change in each VI where the type definition is used. However, because type definitions identify only the data type, only the values that are part of the data type update. For example, on numeric controls, the data range is not part of the data type. Therefore, type definitions for numeric controls do not define the data range for the instances of the type definitions. Also, because the item names in ring controls do not define the data type, changes to ring control item names in a type definition do not change the item names in instances of the type definition. However, if you change the item names in the type definition for an enumerated type control, the instances update because the item names are part of the data type. An instance of a type definition can have its own unique label, description, default value, size, color, or style of control or indicator, such as a knob instead of a slide.
    If you change the data type in a type definition, LabVIEW converts the old default value in instances of the type definition to the new data type, if possible. LabVIEW cannot preserve the instance default value if the data type changes to an incompatible type, such as replacing a numeric control or indicator with a string control or indicator. When the data type of a type definition changes to a data type incompatible with the previous type definition, LabVIEW sets the default value of instances to the default value for the new data type. For example, if you change a type definition from a numeric to a string type, LabVIEW replaces any default values associated with the old numeric data type with empty strings.
    Strict Type Definitions
    A strict type definition forces everything about an instance to be identical to the strict type definition, except the label, description, and default value. As with type definitions, the data type of a strict type definition remains the same everywhere you use the strict type definition. Strict type definitions also define other values, such as range checking on numeric controls and the item names in ring controls. The only VI Server properties available for strict type definitions are those that affect the appearance of the control or indicator, such as Visible, Disabled, Key Focus, Blinking, Position, and Bounds.
    You cannot prevent an instance of a strict type definition from automatically updating unless you remove the link between the instance and the strict type definition.

  • Tables to get the hierarchy used for the global Variable

    Hello,
    we are using a characteristic Reporting Unit "ZCS_RDRUN" with a input ready variable "ZCS_RV_MM_REPUNITHIER_RDM".
    The reporting unit is a hierarchy characteristic and the variable is a hierarchical variable of type Hierarchy node variables fixed to a hierarchy we are using for this query. We do have selected a hierarchy for the input ready variable e.g. Total Group. My question would be is it possible to read out the selected hierarchy of the input ready variable from a table? If YES, from which table? I know that we could read out all input ready variables but i dont know how to read out the hierarchy selected for the input ready variable of type "Hierarchy node variable".
    I would be very thankful for all your help
    Thanks and kind regards,
    Muri

    You check the query run times and other details in the work load analysis (ST03) or using the table RSDDSTAT .
    inorder to check the information using the above two methods -make sure the Bi stats are maintained in your system

  • What font did Adobe use for the Layer names and context bar (OSX PS CS1)?

    I have a problem with my Snow Leopard install. When I disabled the font protection of OSX, to install the full Helvetica Neue set (not just the limited DFont set in OSX), I damaged something. All text in Photoshop CS1 that is used in the input fields of the context bar, and for the names of layers, paths etc is wrong. As text is too big now, the program is harder to use.
    What font is normally used in these locations? I need to know what files to put back.

    Things change.
    Adobe changes things that don't really need changing so they can call it a new .0 version and sell it for a bunch of money.  They also change things to follow modern trends in UI design.
    Sometimes, they want to push other tools to do some of the things Photoshop used to do.  This is so they can make even more money by selling more products!
    Have you been through every intermediate version, or are you making a several version jump?  I ask because the total amount of change in each .0 version has been manageable.  And I personally feel the changes have been worth the money, though perhaps just barely.  That's the key in business.

  • What criteria should I use for the monthly updates

    I am just starting to setup Software Update for SCCM 2012 R2. The configuration is done with the Classifications and Products selected and working.  I selected the Classifications:
    Critical Updates
    Definition Updates
    Security Updates
    Service Packs
    Update Rollups
    Updates
    Now I am just looking for the criteria to use for my Software Update Groups.
    I watched this GREAT VIDEO "SCCM 2012 SP1 and the new way handling Software Updates explained", URL: 
    http://technet.microsoft.com/en-us/video/sccm-2012-sp1-and-the-new-way-handling-software-updates-explained.aspx regarding the "new way" we are to be doing the groups and updates.  The video is
    very informative and explains a lot, but it does not say what criteria is used.
    This is the breakdown from the video, but again it doesn't say what criteria may be:
     • Keep Software Update Groups (SUG) Limited to 1,000 updates
     • Don't split products into different SUG's
     • Enabled Delta replication for the Software Update Points (SUP)
     • Set High priority for the Software Distribution Group
    Software Update Groups
     • Exceptions group (not to deploy)
     • TMG Definition Updates
     • SCEP 2012 Definition Updates
     • Outlook Definition Updates
     • 2003-2010_All Updates
     • 2011_All Updates
     • 2012_All Updates
     • 2013-01_All Updates
     • 2013-02_All Updates
    Deployment Packages
     • TMG Definition Updates
     • SCEP 2012 Definition Updates
     • Outlook Definition Updates
     • 2003-2010_All Updates
     • 2011_All Updates
     • 2012_All Updates
     • 2013_All Updates
    Automatic Deployment Rules
     • Microsoft Outlook 2010/2013 Definition Updates

      ○ Uncheck "Enable the deployment after this rule is run
     • SCEP 2012 Definition Updates
      ○ Run after synchronization
     • TMG Definition Updates
      ○ Run after updates
    I am specifically looking mostly for the Monthly updates and to make sure they are only those needed.  Most I have seen use:
    Superseded:  No
    Expired:  No
    Bulletin starts with "MS"
    I don't really know what the "MS" limits things to.  Sorry a lot of information and not very clearly laid out.

    I am specifically looking mostly for the Monthly updates and to make sure they are only those needed.  Most I have seen use:
    Superseded:  No
    Expired:  No
    Bulletin starts with "MS"
    I don't really know what the "MS" limits things to. 
    I use a similar approach, as one part of my routine.
    When you filter/search on Superseded=NO, that discards the updates which are flagged as superseded, but this depends totally upon your routine and understanding of the nature of supersedence, and it's also time-sensitive, since CM12 will by default, kill off
    superseded updates after a time. A Superseded update *is* deployable, but you'd likely only do that, if the superseding update is unsuitable for your environment for some reason, e.g. it introduces a bug or regression that you can't afford.
    Expired=NO, well, again that's to limit your filter/search results. Since an expired update is not deployable, why bother to have it in your results list, if you are building a deployment. It's handy to know that something is, or has become, expired, if
    you are troubleshooting or analysing a "why did/didn't xyz happen?", but for deploying, expired updates are just useless clutter.
    Bulletin starts with "MS" can be handy to filter out the "non-security" updates, since "security" updates are always issued with an MSyy-nnn bulletin ID.
    Note that the bizarre MS definition of "security update" does not mean that security bulletins cover *all* security-related updates, since there are updates that are released, which do provide security fixes, enhancement, etc, but they don't always attract
    a security bulletin ID, so it really pays to look at "starts with MS" and also "does not start with MS" - I use both, when searching/filtering, as a way to slice the assessment/analysis task in "half" (not evenly sliced ;).
    And also note that some updates (security advisories, hotfixes, rollups) may not fall into the classification you might expect, or, might not be published into the MU/WSUS catalog feed at all..
    An example of a unexpected classification, is the recent 2917500, which is classified under "Feature Packs", even though it is an updated set of revoked root certificates (due to yet another compromised root CA cert). [I noted you didn't mention the Feature
    Packs classification, you might want to revisit that choice...]
    Personally, I'm not yet using ADRs, not because I don't like them, but because our security ops team are being especially painful at the moment and keep changing their mind about stuff, plus, we are undergoing a massive application change cycle and the change/release
    team are hypersensitive just now.
    One method I also use, is to periodically run the "updates needed but not deployed" report, as it reveals to me where I need to sync a new product, or have overlooked an update or misunderstood/incorrectly assessed as "we don't need that, or that doesn't
    apply to us". it also reveals where I have mucked up and not been diligent about taking a templated approach to deployments, e.g. if I forget to distribute to all DPs or whatever.
    I find that even though I might take what I consider to be a very generic approach, others in the forums clearly have different environments/operational models to me, and different needs. For patching, I mainly focus on Windows client OS and Office,
    and not really on Windows server OS, since somebody else handles server builds and patching in my org.

  • What are compatible media files for the Tungsten E2

    I have a video clip that I'd like to put on my Tungsten E2.  The current file is saved as a .wmv.  When I attempt to sync using the Palm desktop software's media feature, I get the message that the file format is not compatible.   I can't find any information as to what are compatible file formats.  Any advice for me?

    Avi's and mpg's are pretty safe.  Wmv's and .mov's won't sync.

  • What does the password stored in the JAGENT wallet do, and what JAVA_HOME should I use for the pw_agent_util.sh command?

    I am configuring the GoldenGate Plugin for OEM. There is a step to create the wallet. The documentation is not clear about the role of the password supplied. If I run the JAGENT as oracle user, should it match the password for the oracle user, or is this password separate? Also, should I use the OEM agent jdk for the JAVA_HOME setting?
    ./pw_agent_util.sh -jagentonly

    Pat,
    Morning.  Good to see that someone is working on using the plug-in for GoldenGate within OEM12c.
    If you are using the plug-in 12.1.0.2, you will be much better off with reporting on GoldenGate processes.  In order to get the 12.1.0.2 plug-in to work, the JAgent 12.1.3.0 is needed and can be downloaded in the Oracle GoldenGate Monitor distribution (Configuring Oracle #GoldenGate Monitor Agent | DBASolved) .  If you are using the old plug-in 12.1.0.1, then the JAgent is embedded with the GoldenGate software (Oracle GoldenGAte (11.2.1.0.1 and later) and Oracle Enterprise Manager 12c | DBASolved).  I recommend taking the new plug-in!
    Now to address you question about the password. The password is stored in the wallet under the GoldenGate home ($OGG_HOME/dirwlt) and is used directly for the JAgent to login to the EMAgent and communicate with OEM.  The user name associated the password is configured in the $JAGENT_HOME (different depending on version, look for Config.properties).  Then in OEM, the username defined in Config.properties and the password in the wallet needs to be provided before OEM will pick up the GoldenGate targets.
    The $JAVA_HOME setting depends on the version of JAgent you are going to run.  The JAgent 12.1.3.0 using JDK 1.7 or higher.  The embedded JAgent using JDK 1.6. 
    Thanks

  • What connection should I use for the Change Management feature?

    I'm trying to evaluate the Change Management feature in SQL Developer 3.2.20.09 (Build MAIN-09.87), but whichever connection I use I get an error: "This is not a valid Enterprise Manager connection."
