Low power operation of electronic apparatus has becomeincreasingly desirable. Medical, REMOTE data acquisition,power monitoring and other applications are good candidatesfor battery driven, low power operation. Micropoweranalog circuits for transducer-based signal conditioningpresent a special class of problems. Although micropowerICs are available, the interconnection of these devices toform a functioning micropower circuit requires care. (SeeBox Sections, “Some Guidelines for Micropower Designand an Example” and “Parasitic Effects of Test Equipmenton Micropower Circuits.”) In particular, trade-offs betweensignal levels and power dissipation become painful whenperformance in the 10-bit to 12-bit area is desirable.

Industrial REMOTE monitoring systems and keep-alivecircuits spend most of their time in standby mode. Manyof these systems also depend on battery power, so powersupply effi ciency in standby state is very important tomaximize battery life. The LT®8410/-1 high effi ciencyboost converter is ideal for these systems, requiringonly 8.5μA of quiescent current in standby mode. Thedevice integrates high value (12.4M/0.4M) output feedbackresistors, signifi cantly reducing input current whenthe output is in regulation with no load. Other featuresinclude an integrated 40V switch and Schottky diode,output disconnect with current limit, built in soft-start,overvoltage protection and a wide input range, all in atiny 8-pin 2mm × 2mm DFN package.

針對(duì)煤礦井下調(diào)度及緊急救援系統(tǒng)的需求，以DTMF編解碼模塊為核心，設(shè)計(jì)了具有自動(dòng)撥號(hào)功能的新型電話系統(tǒng)。該系統(tǒng)利用MT8880對(duì)DTMF信號(hào)的編解碼功能實(shí)現(xiàn)一鍵撥號(hào)和遠(yuǎn)程設(shè)置，通過(guò)檢測(cè)振鈴和忙音信號(hào)，完成自動(dòng)摘機(jī)和掛機(jī)過(guò)程，配合AGC等外圍電路達(dá)到話音清晰流暢的效果。 Abstract: To meet the demand for mine scheduling and emergency rescue system， with using DTMF signal codec as the core， a new telephone system was designed with automatic dialing function. In the system， the DTMF signal encoding and decoding function of MT8880 was used to achieve one-touch dialing and REMOTE setting. The circuit detects the ringing and busy signal， and then completes automatic off-hook and hangup. With AGC(Automatic Gain Control) and other peripheral circuits， the voice was regulated to a clear and smooth effect.

生活中許多目標(biāo)的高度和水平距離需要進(jìn)行測(cè)量。目前主要的測(cè)量方法，仍以傳統(tǒng)的皮尺丈量為主，測(cè)量效率不高，有時(shí)還很不方便，沒(méi)有技術(shù)成熟的數(shù)字式測(cè)高測(cè)距產(chǎn)品。以基本的數(shù)學(xué)方法為理論依據(jù)，利用遙控小車(chē)做為載體，采用角度傳感器測(cè)量角度、霍爾傳感器測(cè)量水平距離等，通過(guò)單片機(jī)LM3S615進(jìn)行數(shù)據(jù)計(jì)算，實(shí)現(xiàn)了對(duì)待測(cè)目標(biāo)物體的高度、水平距離等數(shù)據(jù)的快速、精確和數(shù)字式的測(cè)量，高度測(cè)量精度可達(dá)99.06%，水平測(cè)量精度則可達(dá)98.06%。 Abstract: In our lives， the height and horizontal distance of some goals are needed to be measured. Because the currently used methods are still traditional tape-based measuring methods， and the measuring efficiency is low and inconvenient so some kinds of digital and portable measuring methods or instruments are needed. Based on the basic math theory， this paper designed and manufactured a portable， digital and REMOTE controlled measuring mobile small vehicle， which assembled with angle measuring sensor for angle measurement and Hall sensor for horizontal distance measuring. MCU LM3S615 calculated the height and horizontal distance data gotten from these sensors. The measuring process is simple， the measuring results are more accurate and the measuring efficiency is higher than traditional measure instruments. The accuracy of height and distance measurement can reach 99.06% and 98.06%.
