A Computer-On-Module, or COM, is a Module with all components necessary for a bootable host computer, packaged as a super component. A COM requires a Carrier Board to bring out I/O and to power up. COMs are used to build single board computer solutions and offer OEMs fast time-to-market with reduced development cost. Like integrated circuits, they provide OEMs with significant freedom in meeting form-fit-function requirements. For all these reasons the COM methodology has gained much popularity with OEMs in the embedded industry. COM Express® is an open industry standard for Computer-On-Modules. It is designed to be future proof and to provide a smooth transition path from legacy parallel interfaces to LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA on the one hand and PCI Express and Serial ATA on the other hand.

Convert C to F (Ex1).vi – Exercise 1 solution VI. Convert C to F (Ex2).vi – Exercise 2 solution subVI. Thermometer-DAQ (Ex2).vi – Exercise 2 solution VI. Temperature Monitor (Ex3).vi – Exercise 3 solution VI. Thermometer (Ex4).vi – Exercise 4 solution subVI. Convert C to F (Ex4).vi – Exercise 4 solution subVI. Temperature Logger (Ex4).vi – Exercise 4 solution VI. Multiplot Graph (Ex5).vi – Exercise 5 solution VI. Square Root (Ex6).vi – Exercise 6 solution VI. State Machine 1 (Ex7).vi – Exercise 7 solution VI. The slides can be presented in two three hour labs, or six one hour lectures. Depending on the time and resources available in class, you can choose whether to assign the exercises as homework or to be done in class. If you decide to assign the exercises in class, it is best to assign them in order with the presentation. This way the students can create VI’s while the relevant information is still fresh. The notes associated with the exercise slide should be sufficient to guide the students to a solution. The solution files included are one possible solution, but by no means the only solution.

Abstract: This application note helps system designers choose the correct external components for use with the MAX16948 dualremote antenna LDO/switch, thus ensuring that automobile-regulated phantom antenna supply and output-current-monitoring circuitrymeet performance objectives. An electronic calculator is provided that helps specify the critical external components for theMAX16948, thus reducing design time. The calculator also determines the device's analog output voltage, output current-limitthreshold, and output current-sensing accuracies. The calculator includes new automatic Step By Step feature that assists designerswith component choice. To use the new automatic feature, click on the Step By Step button relative to the desired section.

This paper provided network topology of ZigBee technology by analysing the component of the nodes and researched ZigBee routing algorithm. Aiming at different requirements of transmission mode to choose the different network topologies form can most likely reduce the system cost. And aiming at different network to choose the correct ZigBee routing algorithm can effectively reduced the network energy consumption and improved the reliability of the system. Results show that the communication which used ZigBee mode can improve the transmission rate， cover more area and reduce 40% cost compared with traditional wired communications mode.

1. 簡介 ISIS中的屬性有非常大的用處。一個(gè)特定的對象的屬性是由一些關(guān)鍵字組成，比如，在ISIS中，我們使用封裝的屬性與PCB的封裝關(guān)聯(lián)。 對象，管腳，電路圖都有自己的屬性，如果你想很把這個(gè)功能強(qiáng)大的軟件用好你必須很清楚他們之間的聯(lián)系，這個(gè)軟件和以前你所用過的畫電路的軟件有些不同。 2. 對象屬性 對象屬性有兩個(gè)類型—系統(tǒng)屬性和使用屬性。在ISIS中的這些功能是由一些保留字所組成，不管是內(nèi)部的程序比如ARES和VSM，或者你自己所使用的軟件都是有關(guān)聯(lián)的。 (1)系統(tǒng)屬性 系統(tǒng)屬性在ISIS中是由一些特殊含義的關(guān)鍵字所夠成。比如，一個(gè)元件中的DEVICE屬性是根據(jù)元件庫在分配時(shí)候定義的。這些屬性一般是文本的—比如元件的REF和VALUE屬性可以直接從Edit Component對話框中訪問，但是別的比如DEVICE屬性就是做為圖形操作所生成的結(jié)果。
