head information-
At present, the most of vtr which are used in watch - control occasion for speciality are short of a uniform control - check - alarm system, which brings on the discommodiousness of operation and the user can not know the time of occurring a fault, which reduces the reliability of the watch - control system. therefor, at first, i carefully analyze the servo theory of the vtr which had been produced by chmavc with k mechanism to find out the work rule of the control signal ; second, take out some right control signal ; then for dealing with the problem of vtr in use for watch - control, i choose some right components to design the uniform control system for many special vtr with protel software. it mainly includes the following functions : operation functions of all vtr ( for example : power, play, ff, rew, stop, rec, eject, fwd, rwd, sp, lp ) was controlled by line at the same time ; in, the process of recording, when the tape walks to the end or stops by itself, the system gives an alarm and shows the number of the wrong vtr ; in the process of recording, the system gives an alarm and shows the number of the wrong vtr when the video signal from vidicon is losed ; the system controls all vtr to record on the non - working time when there is something wrong in the guarding section ; the system controls the video from vtr to switch to right monitor
目前，用在監控場合的業務用錄像機普遍缺乏一個統一的控制及檢測報警系統，這就導致了操作的不方便和出現了故障用戶不知道，降低了監控系統的可靠性，為此，我首先對華錄松下生產的k機芯的錄像機伺服原理進行仔細分析，找出各個伺服控制信號的控制變化規律；然後從中選出合適的控制信號；針對目前錄像機在實際監控使用過程中存在的問題，選用合適的元器件；運用protel繪圖軟體，設計了這個多臺業務用錄像機的統一控制系統，她主要包括以下功能：錄像機操作功能（如power play ff rew stop rec eject及正尋反尋帶速設定等）的統一線控控制功能；磁帶在記錄過程中，磁帶到頭和磁帶自己「偷停」的報警，並要能顯示出具體是哪一臺錄像機；在記錄狀態下，攝像頭輸入信號丟失報警，並要能顯示出具體是哪一臺錄像機；在休息或其他不需要記錄時，一旦警戒區有情況，則控制所有機器自動進入錄像狀態的功能；從錄像機輸出的監控圖像信號對監視器的切換功能。Eeg ( electroencephalography ) and meg ( magnetoencephalongraphy ) are noninvasive methods for exploring the neural electrical activities of brain. brain segmentation is a very important and difficult part in eeg / meg research, and many researchers have been working on this field
腦電圖eeg和腦磁圖meg研究屬于無創傷性的腦功能成像技術，主要研究由頭皮測得的腦電或腦磁信號如何獲取腦內源定量的三維信息。When the page is read from disk, the torn bits stored in the page header are compared to the actual page sector information
從磁盤中讀取頁時，頁頭中存儲的殘缺位將與實際的頁扇區信息進行比較。In mass tape storage, an access mode of operation in which the rotating head rotates in a direction that is at an angle ( neither parallel nor vertical ) with the tape movement direction
在海量磁帶存儲裝置中，旋轉磁頭沿與磁帶運行方向構成某一角度（既不平行，也不垂直）的方向旋轉，以進行存取信息的一種工作方式。分享友人
