根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警。-err

本文介绍一种以CPLD[1]为核心、以VHDL[2]为开发工具的时间控制器，该控制器不仅具有时间功能，而且具有定时器功能，能在00：00～23：59之间任意设定开启时间和关闭时间，其设置方便、灵活，广泛应用于路灯、广告灯箱、霓虹灯等处的定时控制。-This article describes a CPLD [1] as the core, VHDL [2] for the development of tools for time controller that features not only has the time, but with the timer function, can be between 00:00 ~ 23:59 arbitrarily set to open time and closing time, and its convenient, flexible, widely used in street lamps, advertising light boxes, neon lights, etc. The timing control.

针对传统快速k-近邻分类算法的缺陷,提出了一种基于近邻搜索的快速k-近邻分类算法―――超球搜 索法。该方法通过对特征空间的预组织,使分类在以待分样本为中心的超球内进行,有效地缩小了搜索范围。 -Rapid response to traditional k-neighbors of the defect classification algorithm, a fast search based on neighbor k-neighbor classification algorithm--- Hyperspherical search. The method of the characteristics of the pre-organization of space, so in order to be classified in the sub-sample of the super-ball as the center to carry out, effectively narrowing the scope of the search.

： 通过 L V D S ( 低压差分信号) 传输方案与单个 L C o S ( 硅基液晶) 分时分色显示， 设计主电路 与头盔结构分离的单 L C o S 硅片彩色头盔显示系统。-: Through the LVDS (Low Voltage Differential Signaling) transmission scheme with a single LC o S (Liquid Crystal on Silicon) color separation time showed that the design of main circuit and the structure of the separation of single-helmet LC o S silicon color helmet display system.

一种关于如何制作稳压电源的方法，详细介绍了稳压电源的各个部分，及参数的设计。-How to make a regulated power supply on the way, described in detail the various parts of the power regulator, and the design parameters.

数控直流稳压电源源程序 本设计由两个电路模块构成：直流稳压源电路（+15V,+5V,-15V），程控电路。并且巧妙得反置使用D/A变换器。使程控输出电压0-9.9手动可调，步距为0.2V。并可预置电压值，采用LED同步显示。-NC DC power source circuit of the design of two modules: the source DC circuit (+15 V,+5 V,-15V), program-controlled circuit. And clever use of a reversal of D/A converter. So that the output voltage programmed manually adjustable 0-9.9, step to 0.2V. And preset voltage value, shows that the use of LED synchronization.
