Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or off, the user can pulse it for a short period (e.g. 鈥淩eboot remote server鈥?.

摘 要 文章以空間監(jiān)控系統(tǒng)為背景,深入研究了JPEG圖像壓縮標(biāo)準(zhǔn)的實現(xiàn)方法,并基于FPGA對其進行了實現(xiàn)和優(yōu)化。文中給出了詳細的實現(xiàn)方法和優(yōu)化過程,測試表明達到了很好的效果。 簡單介紹了有損靜態(tài)圖像壓縮當(dāng)前有兩種比較流行的標(biāo)準(zhǔn)JPEG和JPEG2000。說明了用JPEG方法壓縮的原因。 介紹JPEG基本原理：JPEG對灰度圖像的壓縮處理過程主要包括:圖像分割,離散余弦變換(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脈沖編碼調(diào)制(Differential Pulse Code Modulation,DPCM)對直流系數(shù)(DC),行程長度編碼(Run-Length Encoding,RLE)對交流系數(shù)(AC),霍夫曼(Huffman)編碼等。 JPEG標(biāo)準(zhǔn)的特點是離散余弦變換。 比較詳細介紹壓縮系統(tǒng)的構(gòu)成和實現(xiàn)。實現(xiàn)提及步驟， JPEG壓縮模塊設(shè)計和編碼模塊實現(xiàn)細節(jié)。

This application report discusses the design of non-invasive optical plethysmography also called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both heart-rate detection and pulsoximetering in this application. The probe is placed on a peripheral point of the body such as a finger tip, ear lobe or the nose. The probe includes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) and the other in the infrared spectrum (940nm). The percentage of oxygen in the body is worked by measuring the intensity from each frequency of light after it transmits through the body and then calculating the ratio between these two intensities.

Some time during my development works I had the need of printing the contents of a ListView control. So I wrote down the code for a custom control, named PrintableListView, that solved the following two problems: * extend the print on multiple pages when the width of the list exceeds the width of the print page, * shrink, optionally, the list in a way that the resulting width fits o
