数码绘图板

Multi tool use數位繪圖板(英语:Graphics tablet、Digitizer),又叫作數位板或手寫板,早期是一種使用電磁技術的電腦週邊的輸入裝置,它的使用方式是以專用的電磁筆在數位板表面的工作區上書寫。電磁筆可發出特定頻率的電磁信號,數位板內部具有微控制器及二維的天線陣列,微控制器依序掃描天線板的X軸及Y軸,然後根據信號的大小計算出筆的絕對座標,並將每秒約一百到二百組的座標資料傳送到電腦去。後期技術的演變,當出現電阻式觸控,電容式觸控的技術,可以使用非專用的筆(非電磁式)在數位板上書寫,可以多點輸入,可以大幅降低數位繪圖板的成本。
原理
依照專用的電磁筆內部有無電池供電,可將數位板的技術分成主動式(Active Pen)及被動式(Passive Pen)二種。主動式的電磁筆內部具有以電晶體、線圈、電容所構成的振盪電路。被動式的電磁筆內部則僅有線圈、電容所構成的共振電路。
:無電池的電磁筆:由於電磁筆內部沒有能量來源,所以必須先由數位板的天線發射電磁波能量給筆,無電池的電磁筆內部具有一共振電路,可經由電磁共振效應而接收到能量,並將接收到的能量儲存於共振電路的線圈及電容之中,然後,數位板的天線會停止發射電磁波,此時,無電池的電磁筆便會自動開始發射電磁信號直到共振電路中所儲存的能量被消耗完為止。由於被動式數位板的工作分成二階段:先發射、後接收,且需如此週而復始的不停循環,所以被動式的數位板較為耗電,也必須注意週遭環境的電磁波干擾(EMI)。
:有電池的電磁筆:電磁筆內有能量來源,所以筆會持續地供應電能到振盪電路而發射特定頻率的電磁波。在此同時,由於數位板的天線不再需要發射能量給筆,天線只需用於接收信號,所以主動式的數位板不僅較為省電,同時座標資料率(Report Rate)也可快上約一倍。

手寫板
用作識別文字的專用數位繪圖板稱為手寫板。原理跟數位繪圖板差不多,但通常不能像它們般靈敏,而且面積較小。

1 I having trouble getting my ResourceDictionary.MergedDictionaries to load from app.xaml. My WPF app has a static class with a Main defined and startup object set to it. Within Main I created an instance of App and run it. The override OnStartup fires and the mainwindow.cs InitializeComponent gives the error "Message "Cannot find resource named 'MaterialDesignFloatingActionMiniAccentButton'. If I put the resources in the mainwindow.xaml everything is fine, but I wanted them to load at the app level so I they are not in each page. Any help appreciated. public partial class App protected override void OnStartup(StartupEventArgs e) base.OnStartup(e); var app = new MainWindow(); var context = new MainWindowViewModel(); app.DataContext = context; app.Show(); from the Main.. var app = new App(); app.Run(); app.xaml.. <Application x:Class="GS.Server.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:...
up vote 2 down vote favorite There is a clear pattern that show for two separate subsets (set of columns); If one value is missing in a column, values of other columns in the same subset are missing for any row. Here is a visualization of missing data My tries up until now, I used ycimpute library to learn from other values, and applied Iterforest. I noted, score of Logistic regression is so weak (0.6) and thought Iterforest might not learn enough or anyway, except from outer subset which might not be enough? for example the subset with 11 columns might learn from the other columns but not from within it's members, and the same goes for the subset with four columns. This bar plot show better quantity of missings So of course, dealing with missings is better than dropping rows because It would affect my prediction which does contain the same missings quantity relatively. Any better way to deal with these ? [EDIT] The nullity pattern is confirmed: machine-learning cor...
