An efficient timer management module design

The timer is one of the basic elements of the normal operation of the communication protocol is mainly used for a variety of digital timer

and frame retransmission task. The communication protocol used in the SCM system timer, timing accuracy is not required, but the number of requirements. Hardware resources are limited, it is impossible for every single task is assigned a hardware timer, only through a single hardware timer simulate a number of software timers to meet the timing needs agreement.


These software timer data structure to organize themselves, and provides a uniform interface, called "Timer". Timer management are mainly two kinds of method:


(1) static array method. Timer node is stored in the array. The advantage is simple logic, occupy less ROM. However, this program has significant disadvantages: when the hardware timer interrupt occurs, the subtraction operation of all timer node, the time overhead and delay uncertainty (related to the timer number).


(2)delta linked list method. Ascending order to form a linked list in accordance with the timing value of the timer. A timer value of timer in front of all the timer value plus the value of the node. Thus, in each clock interrupt handler, only the subtraction operation on a timer node, greatly reducing the time overhead. However, the complex program logic, ROM, dosage, require frequent allocation of recovery of memory, easy to form the memory fragmentation.


The timer management module design is based on a static array method. Use a timer node array to hold all of the timing of the request, a representative of an available timer node of the array. Each timer node has a status indicates that the timer is in idle, or overflow state. Timing value of the timer and the timer expires, the message to be sent is also stored in the timer node, in order to achieve a hardware timer to provide users with a number of software timers.


In order to solve the problem of interrupt processing time overhead, the introduction of an auxiliary timer module, auxiliary timer value is always equal to the minimum timing value of all the timer node. In the hardware timer interrupt processing, only the auxiliary timer subtraction operation, which will greatly reduce interrupt processing time.


Start a timer, the main node to node array in an idle state is set to use. If the new timer is enabled, all timers from time to time to the minimum value, but also to update the auxiliary timer. Function pointer to point to the timer message and time value parameters, start the timer process shown in Figure 2. Successful start-up timer, return the node ID number of the timer.


Software timer is driven by the hardware digital timer. In the hardware timer interrupt, the first auxiliary timer value minus 1. If the auxiliary timer value is 0, then the timer value minimum timer has timed out, the corresponding message should be sent to the user task, the node set to the idle state, and re-calculate the timing values ??of the other nodes, and find the timing value the smallest node, update the auxiliary timer.

Thermometer use after disinfection

The sterilization of a digital thermometer involving soap, water and denatured alcohol is a process that members of the boomer generation know well. But this process has changed and it has changed for reasons unrelated to how effective it was in killing germs.


Wipe off the bulb thermometer with denatured alcohol after its soap and water wash. It should then be placed in a clean protective container. It may also be placed in a covered container of denatured alcohol.


Make sure that you wipe off the ENTIRE AREA of the thermometer that has been touched by the patient. If possible, use denatured alcohol since this is the best bactericidal agent, but you must check with the thermometer's directions since some do not tolerate its use.


Get a new thermometer if you have one with mercury in it. Sterilize other bulb thermometers, using colored alcohol for example, by initially washing it in soap and water.


Use the disposable coverlets on those models designed for their use. Following use, simply wipe off the area of the thermometer that has been exposed to a patient's touch.


Wipe off any area of a digital ear thermometer touched by a patient immediately following use. With the unit's next use, then apply the disposable ear tip. The chances of contamination of an ear thermometer are obviously far less than that for an oral unit, but never underestimate a toddler's ability to slobber over great distances.


Check the instructions that come with a digital thermometer for the way it should be cleaned. This is necessary because different thermometers have different ways of sterilization.

Electronic digital timer automatically sets the heating time

Electronic digital timer capable of automatically setting the time of heating according to the quantity and kind of food being cooked.


The mechanical timer requires the timer needle to be manually rotated whenevercooking time is set, leading to a very much complicated operation. Since indication by the timer is always made solely by means of the needle, an actual lapse of time since the commencement of heating can not be found, if the needle is fixed at a pointof said set time. Conversely where the needle is made to move as time goes on, then it is impossible to trace an originally set time, giving rise to the erroneous observation of time indication on the panel of the timer or the incorrect setting ofcooking time. These errors have often caused the misunderstanding of the initially set time or the wide displacement of a set time from a desired value, resulting in insufficient cooking.


According to this invention there is provided an electronic range fitted with a high frequency generator which comprises a device for setting a value representing the quantity of food being cooked; a device for indicating said set value in theform of digits; a pulse generator; a device for varying the period of pulses generated by said pulse generator according to the quantity and kind of food being cooked; a counter for counting pulses from the pulse generator upon the commencement of afood-heating operation; and a device for bringing the operation of the high frequency generator to an end when a prescribed relationship arises between the counts made by the counter and a value denoting an originally set time.


A general electronic range sets a time of cooking food by a timer. In this case, heating time is set by searching for an optimum length of cooking time for the quantity and kind of food being cooked or by the experience or sense of a personundertaking cooking. Accordingly, the time of cooking the same quantity and kind of food varies from person to person using an electronic range, resulting in a failure to carry out proper cooking.


It is accordingly the object of this invention to provide an electronic range provided with a compact electronic digital timer which can automatically set a proper time of cooking or heating for the quantity and kind of food being cooked and,where required, indicate an originally set time as well as a lapse of time from the initial point of cooking time set in the form of digits.

How to change the different units of the digital thermometer

The digital thermometer is a device that is very good to be at home in the medicine cabinet.There are times when the digital thermometer may not read the temperature in the unit you are familiar with. If you live in the United States,but have a thermometer that reads temperature degrees Celsius, and you want to go to they could turn into units Fahrenheit. How can you change the digital thermometer to different units?


Most digital thermometers have a small menu that you can access by pressing the Start button and hold until the menu flashes on the screen. Some digital thermometers have an additional button on the side of the access to this feature. In order to change the temperature reading on the thermometer must be moved through the list to find the option of conversion. Highlight to read the temperature and want to go out and then in the menu by pressing and pressing the start button again.


If the Digital Thermometer your only reads in Celsius, but you're used to system Fahrenheit, you can also use a similar formula to change the unit of measurement. Using the reading you currently have on the thermometer, you will need to multiply by 9. With that you receive the answer, divide it by 5. Now, you can add 32 to the number in order to reach a temperature reading in Fahrenheit.


With a digital thermometer in hand, you press the button in the upper part of the device. Click on the button until the screen lights up. Will run the version on the button and the digital thermometer in your. Must be set to read on the screen at 0 degrees. Look next to see what the unit of measurement is set. Will have to either type (F 'for Fahrenheit, or' c 'for Celsius.


Another way to change the unit of measurement temperature on the thermometer read your digital standard for the use of mathematical equation. To do this, you will need to have a calculator, a pencil and paper ready.


If you want to use to read degrees Celsius, but the digital thermometer only reads your temperature in Fahrenheit you can change the reading with a formula easy. Take readings you currently have and put 32 of it. The answer is that the gap by 9 and then double what you have at this stage by 7. By following these simple math equation will end up with a degree Celsius.


If you're near a computer, and there to read the temperature with you, you can easily convert the unit converter with temperatures on the Internet. Go to the site on the Internet, such as the National Weather Service, and major figures in the converter. If you have a percentage, then you want to convert to Fahrenheit and vice versa.

How to buy a basal digital thermometer

A regular thermometer is little bit daunting to use as it requires you to keep still for few minutes and moreover it is not perfect in giving readings. A basal digital thermometer is more reliable as it gives you reading by 10th's of a degree. A basal digital thermometer is more accurate than a simple thermometer.


How to use a basal digital thermometer?


Use the basal digital thermometer first in the morning before getting out of bed because it is the best time to measure the temperature. There on you should try to take the temperature from the basal digital thermometer at as close to the same time each day as possible so that you can fill up your daily chart correctly.


The best time to take advantage of digital basal thermometer is when you have taken a five hour uninterrupted sleep. Moreover you can use your digital basal thermometer orally, vaginally or rectally depending on you that which style is best suited to you.


Basal digital thermometer is a latest innovation which can keep you informed of your normal body temperature throughout the day so that you can get to know of the times when your body temperature is high or when your body is going to ovulate.


How to buy a basal digital thermometer?


You can have many options to buy a basal digital thermometer from any route you like. You can have online routes to make purchases of basal digital thermometer. Online stores are widely present in the world but you need to be confident about the route. Moreover you can have another way to buy the basal digital thermometer and that is by visiting the shop on your own.


A basal digital thermometer is extra sensitive thermometer which tracks your body temperature minutest shift or basal temperature. A basal temperature is the normal temperature of the person after awakening in the morning. The basal temperature rises at times of ovulation that is hormonal changes. A basal digital thermometer is easy to use near the middle of the menstrual cycle.

Difference between basal digital thermometer and a regular thermometer


A basal digital thermometer is often used by women when they want to know about their fertile period or ovulation. You can find different types of basal thermometers but a basal digital thermometer is best for the usage especially when you want to make a chart of your basal digital thermometer.

Argentina to protest British "militarization" of the United Nations in recent Falklands

Argentina will lodge a complaint with the United Nations Security Council over the U.K.’s “militarization” of indoor-outdoor thermometer the southern Atlantic Ocean around the Falkland Islands, President Cristina Fernandez de Kirchner said.


The dispute between Argentina and the U.K., which went to war over the islands in 1982, deepened in 2010 after four British companies announced plans to search for oil around the archipelago, located about 480 kilometers (280 miles) from the South American mainland. The explorers are targeting 8.3 billion barrels in the waters this year, three times the U.K.’s reserves.


“This is a regional and global issue because they are militarizing the South Atlantic once again,” Fernandez told an audience at the presidential palace that included her Cabinet and the nation’s military chiefs. “There is no other way to interpret the decision to send a destroyer, a huge and modern destroyer, to accompany the Royal heir, whom we would have loved to see in civilian clothing instead of a military uniform.”


The Foreign Ministry will protest Britain’s decision to send one of its newest destroyers, HMS Dauntless, to the islands, to replace an older ship at the same time Prince William is deployed to the archipelago, Fernandez said last night in Buenos Aires. The 58-year-old president has rounded up fresh support in Latin America for her position in recent weeks.



London-based Borders & Southern Petroleum Plc will drill the Stebbing prospect this month, one of three Falkland areas that Morgan Stanley ranks among the world’s top 15 offshore roller blind prospects this year.


Rockhopper Exploration Plc, based in Salisbury, England, is seeking partners for the $2 billion development of its Sea Lion field, the islands’ first economically viable oil find.


Argentina traces its ties to the Falklands to 1820 when Colonel David Jewett claimed possession of the islands in the name of the United Provinces of the Rio de la Plata. England assumed military control of the archipelago in 1833, evicting Argentine authorities the following year.


Tensions between the two countries escalated over William’s arrival at the islands last week for a tour of duty as a military pilot. Argentina’s Foreign Ministry said in an statement last week that Argentines regret that William traveled to the islands with the “uniform of a conqueror.”


“We are people that have suffered too much violence in our country, we are not attracted by games of guns and wars,” Fernandez said at the ceremony, in which she ordered a three- decade old report on the war to be reviewed and declassified.


In a show of support for Argentina’s claim, Brazil, Uruguay, Paraguay, Nicaragua, Cuba and Antigua and Barbuda have agreed to ban ships flying the Falkland Islands flag from their ports.



Argentine military dictator Leopoldo Galtieri ordered the solenoid valve invasion of the Malvinas, as the Falklands are known in Argentina, on April 2, 1982. Argentine troops were defeated by British forces on June 14, 1982. The war bolstered the government of then-U.K. Prime Minister Margaret Thatcher, known as the “The Iron Lady,” and helped her win elections the following year.

American football, NBC, I'm sorry "obscene gestures": singer flip birds in the Super Bowl halftime show

The NFL and NBC issued apologies late Sunday after a performer extended her middle finger on camera during the Super Bowl halftime show starring Madonna.



M.I.A., a British singer who was performing alongside Madonna tomato paste, flipped the bird on air just seconds after a digitized blurring occurred on screen. The performer also may have uttered an expletive on camera, according to various published reports, but it was not clearly heard during the telecast.



The statements issued after the game hinted at some tension between NBC and NFL over who was more responsible for the mishap, with NBC acknowledging its screening technology didn't work fast enough--but also noting the network left the hiring of M.I.A. to the league.



An NBC spokesman explained that a system in place during the telecast attempted to blur the image but was late by two-third of a second, or 20 frames. He could not identify how many seconds of delay were in place during the broadcast.



"The NFL hired the talent and produced the halftime show," the network said in a statement. "Our system was late to obscure the inappropriate gesture and we apologize to our viewers."



The spokesman could not confirm that there was hydraulic hose fittings any audible expletive from M.I.A. that was heard on camera.



The NFL issued a statement of its own regretting the incident, but used a far more loaded adjective to describe the on-air gesture. "There was a failure in NBC's delay system. The obscene gesture in the performance was completely inappropriate, very disappointing, and we apologize to our fans," read the statement.



"Obscene" is a far more dangerous word than "inappropriate" given it borrows from the term the FCC employs in its monitoring of language and imagery used on broadcast TV.



The incident could mean NBC is headed for the kind of controversy CBS found itself in eight years ago as a result of the infamous "wardrobe malfunction" that occurred during the halftime show, when singer Janet Jackson's nipple was gas thermocouple exposed on the air as she performed with Justin Timberlake.



Sources suggested that the NFL didn't see any sign of M.I.A. making such a gesture during rehearsals preceding the Super Bowl.

For Woods, Early Lesson in Pressure Resonates

Before Tiger Woods became the Mariano Rivera of golf, he struggled to close out a victory on the PGA Tour the way Kyle Stanley and Spencer Levin have in recent weeks.



At the 1996 Quad City Classic, his third event after ac power cord turning professional, Woods started the final round with a one-stroke advantage that he stretched to three after two holes. But he was derailed by a quadruple bogey on one hole and a four-putt on another.


Woods wound up tied for fifth, four strokes behind Ed Fiori, a 43-year-old who had gone 14 years between victories. Afterward, the runner-up, Andrew Magee, observed: “You know, we are not going to lie down out there. I think this was a blessing in disguise for Tiger.”


On Tuesday, speaking in advance of his first Pebble Beach National Pro-Am appearance since 2002, Woods echoed Magee.


“What that allowed me to do is understand and feel the heat at this level,” Woods said, adding: “So that helped a lot going through that one tournament. It showed me that, one, I could get there, and two, where I needed to improve.”


The next month, Woods charged from four strokes back to defeat Davis Love III in a playoff in Las Vegas for the first of his 71 tour victories. Since the 1996 Quad City tournament, Woods has taken at least a share of the lead into the final round of 51 PGA Tour events and won 48 of them. He held a piece of the lead in his opening event of the 2012 season, in the United Arab Emirates, and finished tied for third.



“I think for me, personally, I’ve always been excited about gas thermocouple being in that position,” Woods said. “One, I know I’ve played well to get there, so just trying to do the same things I did to get there and hopefully, it will be enough.”


Woods has won the Pebble Beach National Pro-Am once, in 2000 when he erased a seven-shot deficit in the final seven holes to reel in the rookie Matt Gogel, the 54-hole leader. Gogel demonstrated he learned from the experience by carving out a victory here in 2002.


For those who find themselves carrying the lead into the final day, experience is the best caddie. On that day in 2000, Gogel played the front nine in 31 strokes. That was the same score Woods posted in the pressure cooker that is the back nine, where Gogel carded a 40.


Recalling his mind-set, Woods said, “Matt had never won a golf tournament at the time, and I figured if I could just somehow get within one or two of him with a few holes to go, that was kind of the goal.”



Stanley employed the same thinking on Sunday in Scottsdale, Ariz., when he caught and passed Levin, who has not won on the tour, in much the same way that Brandt Snedeker had tomato paste caught and passed Stanley in La Jolla, Calif., the previous week.


“It’s very hard to win out here,” said Woods, who once made it look easy. From 1997 to 2009, he averaged nearly six wins a year.


Woods’s last official PGA Tour title came at the BMW Championship in September 2009, as his path to the winning circle has been diverted by personal issues and injuries. (Woods won the Chevron World Challenge, an unofficial PGA Tour event that he hosted, in December.)


“I feel very at peace where I’m at,” he said. “I had to make some changes, and that took time, and I’m starting to see the results of that now, which is great.”



Woods feels pressure to win this week, but not for the solenoid valve obvious reason. He knows there are a lot of people eager to see him win again, but there are also two fans who simply desire to see him.



“My kids are becoming at an age now where they want to see Daddy on TV,” Woods explained, referring to his daughter Sam, 4, and his son, Charlie, who turns 3 Wednesday.


He said he tells them that to be on TV, he has to play well. Their response, Woods said, smiling, is always, “Well, Daddy, can you please play well?”


Woods added, “I get more satisfaction out of that part of my life now, so golf is more enjoyable than it used to be, for sure.”
