High-speed Precision Numerically Controlled Tapping Using Dual Predictive  Control

12V or Adjustable, High-Efficiency,Low IQ, Step-Up DC-DC Controller

A major societal challenge for the decades to come will be the delivery of effective medical services while at the same time curbing the growing cost of healthcare. It is expected that new concepts-particularly electronically assisted healthcare will provide an answer. This will include new devices, ...

12bit 低功耗DAC 数模转换器 The MAX5302 combines a low-power, voltage-output, 12-bit digital-to-analog converter (DAC) and a precision output amplifier in an 8-pin µMAX package. It operates from a single +5V supply, drawing less than 280µA of supply current.

The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium- ...

Low-power Solution for DSP Intensive Audio Applications

1．Describe a Θ(n lg n)-time algorithm that, given a set S of n integers and another integer x, determines whether or not there exist two elements in S whose sum is exactly x. (Implement exercise 2.3-7.) #include<stdio.h> #include<stdlib.h> void merge(int arr[],int low,int mid,int high){   ...

在本课中，我们要用一个按键来实现跑马灯的 10 级调速。这又会涉及到键的去抖的问 题。  本课的试验结果是，每按一次按键，跑马速度就降低一级，共 10 级。  这里我们又增加了一个变量 speedlever，来保存当前的速度档次。  在按键里的处理中，多了当前档次的延时值的设置。  请看程序：  ―― ...

Lithium–sulfur batteries are a promising energy-storage technology due to their relatively low cost and high theoretical energy density. However, one of their major technical problems is the shuttling of soluble polysulfides between electrodes, resulting in rapid capacity fading. Here, we present ...
