【正文】 s National Basketball Association (WNBA) playoffs. And it has also made American heroes out of its player and coach legends like Michael Jordan, Larry Bird, Earvin Magic Johnson, Sheryl Swoopes, and other great players. At the heart of the game is the playing space and the equipment. The space is a rectangular, indoor court. The principal pieces of equipment are the two elevated baskets, one at each end (in the long direction) of the court, and the basketball itself. The ball is spherical in shape and is inflated. Basketballs range in size from in (7276 cm) in circumference, and in weight from 1822 oz (510624 g). For players below the high school level, a smaller ball is used, but the ball in men39。t start planning...

However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。 TH0=0。 T[m]=TH0*256+TL0+65536*COUNT。i5。 ET0=1。 dd[1]=d%1000/100。//5*7 點陣字符 write_cmd(0x0c)。 RW=0。 } void write_cmd(uchar cmd)//寫指令子程序 { RS=0。 MO=0。 for(i=0。 Init()。 void Write_Datas(uchar address,uchar Wdata)。 uchar W[5]={1,2,3,4,5}。 sbit MO=P3^3。 圖 仿真圖（一） 當調(diào)節(jié)信號發(fā)生器改變輸入的頻 率值時，單片機通過對其進行計數(shù)并運算處理，在數(shù)碼管上面對應(yīng)的顯示當前值。 圖 主控芯片仿真 由于汽車上常用的轉(zhuǎn)速傳感器為霍爾式，集成的傳感器其輸出的信號為脈沖信號。最后將所得的值賦給數(shù)碼管顯示。設(shè)計中在輸入端串聯(lián)了一片 74LS04 的六非門芯片，提高輸入的驅(qū)動能力，以便于單片機處理。 圖 系統(tǒng)最小系統(tǒng) 濾波電路及 LM324 芯片 LM324 芯片是 差動輸入的四運算放大器。在 FLASH 編程期間，此引腳也用于施加 12V 編程電源（ VPP）。此時， ALE 只有在執(zhí)行 MOVX， MOVC 指令是 ALE 才起作用。 RST：復位輸入。這是由于內(nèi)部上拉的緣故。當 P1 口的管腳第一次寫 1時，被定義為高阻輸入。其中 作為信號的輸入， P1 口用作 LCD 的數(shù)據(jù)線， 、 、 口用作LCD 的 控制信號。 關(guān)鍵詞： 轉(zhuǎn)速 單片機 顯示 控制 LCD1602 發(fā)動機轉(zhuǎn)速 電控系統(tǒng)程序設(shè)計及仿真 2 1 引 言 問題的提出 目前汽車上轉(zhuǎn)速表顯示過于復雜，并且處于安全的 考慮，要用單片機知識及常見的元器件搭建出能檢測汽車發(fā)動機或者其它裝置的轉(zhuǎn)速，并相應(yīng)的進行控制將其顯示在監(jiān)視員的視野之內(nèi)，這樣將減少因發(fā)動機轉(zhuǎn)速而造成的人身危害。 任務(wù)與分析 本文是應(yīng)用 MCS51單片機原理和控制理論設(shè)計 發(fā)動機轉(zhuǎn)速檢測并 控制的硬件電路，利用 C語言進行程序設(shè)計。 設(shè)計框圖如圖一所示。 P0能夠用于外部程序數(shù)據(jù)存儲器，它可以被定義為數(shù)據(jù) /地址的第八位。 P2 口當用于外部程序存儲器或 16 位地址外部數(shù)據(jù)存儲器進行存取時， P2口輸出地址的高八位。當振蕩器復位器件時，要保持 RST 腳兩個機器周期的高電平時間。另外，該引腳被略微拉高。 XTAL1：反向振蕩放大器的輸入及內(nèi)部時鐘工作電路的輸入。該 運放放 大器可以工作在低到 伏或者高到 32 伏的電源下，靜態(tài)電流為 MC1741 的靜態(tài)電流的五分之一。 圖 信號輸入濾波電路 顯示設(shè)備 發(fā)動機轉(zhuǎn)速 電控系統(tǒng)程序設(shè)計及仿真 8 圖 轉(zhuǎn)速顯示設(shè)備 LCD1602 控制執(zhí)行機構(gòu) 通過汽車理論知識學習，我們知道汽車發(fā)動機不能超過某一轉(zhuǎn)速。當轉(zhuǎn)速值大于設(shè)定值時，控制電機運作，指示燈亮。在仿真中，采用霍爾傳感器的原始信號即正弦信號來作為輸入信號，利用 LM324芯片的比較功能對其進行濾波處理將其轉(zhuǎn)換成對應(yīng)的脈沖信號。調(diào)節(jié)信號發(fā)生器為圖 18HZ時，LCD 顯示值為 1080r/min，其值和 18*60=1080 相同。 bit Flag。 //權(quán)值 void Init(void)。 // // 主函數(shù) // void main(void) { 發(fā)動機轉(zhuǎn)速 電控系統(tǒng)程序設(shè)計及仿真 25 uchar msg1[14]=Current Rev is。 LCD_Init()。i14。 } LCD_Disp(dis_dat)。 RW=0。 P1=date。//整體顯示 ,關(guān)光標 ,不閃爍 write_cmd(0x06)。 dd[2]=d%1000%100/10。 IT0=1。i++) { sum+=T[i]*W[i]。 TH0=0。 TL0=0。t charge you more than 35% of your pensation if you win the case.

There is also evidence of a higher proportion of perinatal plications (plications arising around the time of giving birth) among children with autistic symptoms. These plications include maternal bleeding after the first trimester and meconium in the amniotic fluid. (Meconium is a substance that accumulates in the bowel of the developing fetus and is discharged shortly after birth.) Some evidence suggests that the use of medications during pregnancy may be related to the development of autistic symptoms. As newborns, children with autistic behaviors show a higher rate of respiratory illness and anemia than healthy children. ALLERGIES, INFECTIONS, AND IMMUNIZATIONS. Some professionals believe that autistic disorders may be caused by allergies to particular fungi, viral infections, and various foods. No controlled studies have supported these beliefs, but some parents and professionals report improvement when allergens and/or certain foods are eliminated from the diet. Vi
