Application Skills of High Efficiency Boost Converter
Application Skills of High Efficiency Boost Converter
Application Skills of High Efficiency Boost ConverterThe development of power circuits for portable electronic devices requires design engineers to extend battery life by maximizing power and reducing the power consumption of the entire system. This promotes the size of the device itself to become smaller, which is beneficial to the design of end products. High flexibility. One of the most important components of this design is the power management IC or DC/DC converter.High-efficiency DC/DC converters are the foundation of all portable designs. Many portable electronic applications are designed to work with a single AA or AAA battery, which poses a challenge to the power supply design engineer. A constant 3.3V system output is generated from an input voltage of 850mV~1.5V. The synchronous boost DC/DC converter is required to work at a fixed switching frequency, with an on-chip compensation circuit, and requires miniature low-height inductors and ceramic capacitors. It is best to use a miniature IC package to reduce its total footprint in the device design.A proven circuit design consisting of a thin SOT IC package and a small number of external components has realized a single cell to 3.3V/150mA converter with a 90% efficiency of only 7×9mm2 board area. When working under a single battery input (1.5V), a load current between 25mA and 80mA may achieve an efficiency of more than 90%. An external low-current Schottky diode (although not required) will maximize efficiency at higher output currents.This circuit design integrates a high-efficiency DC/DC converter with a low gate electrode voltage internal switch with a rated resistance value of 0.35Ω(N) and a typical resistance value of 0.45Ω(P). In the entire operating temperature range, the switch current limit is generally 850mA, so that the output power of 0.66W and 2.5W can be achieved respectively when the new alkaline AA single-cell battery and two-cell battery are input.Current mode control provides excellent input line and output load transient response. Slope compensation (which is necessary to prevent crossover harmonic instability when the duty cycle exceeds 50%) can be integrated into the converter to maintain the constant current limit threshold along with the circuit, regardless of the input voltage.Main featuresTwo characteristics of advanced power management IC design will affect its efficiency: the integration of internal feedback mechanisms and the addition of power saving modes that can save energy during operation. The increased internal feedback loop compensation no longer requires external components, thereby reducing the total cost and simplifying the design process. By activating the power converter only when needed to keep the output voltage modulation within 1%, the power saving mode of operation improves the converter efficiency at light loads (ILOAD
Aretha Franklin's Detroit Home Is Back on the Market with a Respectable Price Increase
Aretha Franklin's Detroit Home Is Back on the Market with a Respectable Price Increase
Your home is your castle, and now's your chance to own one that belonged to music royalty. A Detroit-area property owned by the late Queen of Soul Aretha Franklin is for sale. The house had been listed at $800,000 in October and was removed from the MLS about six weeks later. Now it's back on the market with a new look and a new price tag: $1.2 million."The home wasn't lived in for 15 years and was in disrepair," says listing agent Michael Hermiz, of RE/MAX New Trend in Farmington Hills, Michigan. "Sabrina Owens [Franklin's niece and estate executor] took it off market and fixed it up. The remodel was very tastefully done."Indeed. The impressive 4,148-square-foot five-bedroom Colonial, which Franklin bought in 1997, is located in a gated community in upscale Bloomfield Hills, Michigan. Its circular drive delivers you and your guests to the home's courtyard entrance. An expansive two-story foyer greets you, featuring elegant marble flooring and a crystal chandelier. It opens to the two-story great room, which currently holds Franklin's own red grand piano, to be auctioned off at a later date. Franklin loved to cook, and the new owner will enjoy her gourmet kitchen, which has white cabinets, black granite counters and an oversized island. The space has all of Franklin's original appliances. "Whoever is so lucky to get this space will be cooking in the Queen of Soul's kitchen," Rodney Howell, a Detroit-area stylist who staged the home, said in an interview with a local Fox news station. The formal dining room includes a stunning custom-made chandelier that Franklin owned and loved. It formerly hung in another of her residences, and was brought here to add more of her personal style. A stately master suite is also on the first floor, featuring the original floors and marble bathroom. Another special touch is the floral etched shower surround, custom made for Franklin. Imagine the bragging rights to sing in the shower where Franklin readied herself for the day? The home has a total of five bedrooms, five and a half bathrooms, library and a finished walkout lower level, with plenty of space for a family or for entertaining. Two oversized cedar closets were installed in the home, with plenty of room for your evening gowns and wardrobe changes.The home backs up to the community amenities, including a pool, tennis court, clubhouse, pond, and walking trail, and has elevated decks from which to take in the view. The renovation also included plenty of practical improvements, including a new roof, furnace and hot water heater, and a restained deck. While the price of this property increased 50% from the last time it was listed, Hermiz says it's in line with similar listings in the area. Zillow lists the home's value at $1.16 million. Another home on the same street is listed for $1.05 million-of course it doesn't have the provenance that Franklin's home does. Previously, the listing was a fixer upper, but the renovations make it move in ready."Some parts were kept original to how she lived, and some things were made newer," says Hermiz. "Remodeling the home preserves Aretha Franklin's legacy. It's a turn key property and a once in a lifetime opportunity."

Definately, if it's bright and in the dark it can strain your eyes1. please help me buy a mobile phone?Wait just a little, soon the Iphone 4g will come out and it will be the best mobile ever. REMEMBER: Iphone> Other touch screens.2. Phoning a mobile phone from the UK?The code for the USA is 001 (then enter the 10 digit american mob number)3. anyone who doesn't use a mobile phone?Very rarely, I think they are often an invasion of privacy. Mine and those around me. I doubt I could teach today as students phones are probably ringing in class. I did not permit that in my day but would be overwhelmed today. Cell phones should be used in the same way fire extinguishers are used, especially in cars. From the cell phone users I have learned that seldom is anything of consequence is discussed. I had some student complain about the price of text books but had the latest, do all, devices in their possession.4.

How does focus work on mobile phone cameras?Regarding "always wastes huge amount of time", this is not unlike many compact cameras using the contrast-based AF, the focusing algorithm has to blindly try various lens positions and compare the results, because it has no other way to know what the correct focus distance could be.Some smartphones, having specialized focusing hardware, can also use faster methods, that often give near zero shutter lag:More about auto focusing methods: How does autofocus work?7. How do I unlock my mobile phone?There are three ways your phone could be locked: How to activate your SIM card How to unlock your phone How to unlock your home screen Note: Devices sold on or after December 1, 2017 must be unlocked by default. How to unlock your mobile phone Insert the Fizz SIM card in your mobile phone. Your phone will ask you for an unlock code. Your unlock code will be provided free of charge by the mobile service provider who originally sold your phone. After you correctly type the unlock code, your phone will display a confirmation message that the network lock has been removed. Note: Some phone settings may be misconfigured following this process. After unlocking your phone, reboot it (power cycle) by holding down your phone's start button for 10 seconds. Then check the configuration of your device's APN (see below). How to configure your phone's APN APN information for Fizz is as follows: APN type: default, mms OR internet mms (Depending on the device) Other fields should be filled by default or not essential.

Al-Qaeda Video Claims London Bombings
Al-Qaeda Video Claims London Bombings
One of the four London suicide bombers, in a posthumous message broadcast by the al-Jazeera channel today, said he was driven to his actions in response to the "atrocities" committed against Muslims.Speaking in English with a northern English accent, a man said by the channel to be Mohammad Sidique Khan outlined his motivations for taking part in the attack, which was accompanied by a separate message by al-Qaeda's number two Ayman al-Zawahri."I and thousands like me have forsaken everything for what we believe in. Our driving motivation does not come from tangible commodities that this world has to offer. Our religion is Islam," he said.Looking relaxed but gesticulating with a pen as he spoke, Sidique was filmed wearing a turban and a waterproof jacket and against the background of a coloured tapestry."Your democratically elected governments continue to commit atrocities against my people over the world."Their support makes you directly responsible just as I am directly responsible for protecting and avenging my Muslim bothers and sisters," he said, in an apparent message to Western countries "Until we feel security you will be our targets. Until you stop the bombing the gassing, the imprisonment and torture of my people we will not stop this fight."We are at war and I am a soldier, now you too will face the reality of this situation," he said.The suicide bombings on London's transportation network on July 7 killed 56 people and injured hundreds.In his message, Zawahri warned there would be more attacks like the London suicide bombings on Western countries that took part in the US-led wars on Iraq and Afghanistan.Zawahri said the July 7 attacks on London's transport system were a "slap in the face" for British Prime Minister Tony Blair, adding that they had "moved our battle right to the enemy's doorstep".The tape appeared to be an extract from a videotape already partly aired by al-Jazeera on August 4, in which Zawahri warned Britain and the United States of more attacks."We have repeated again and again, and here we are warning one more time - all those who took part in the aggression on Iraq, Afghanistan and Palestine, we will respond in kind," Zawahri said in the tape, which bore English subtitles."And as they have let rivers of blood run in our countries, we will, God willing, erupt volcanoes of anger in their countries," he said in the tape, which showed him wearing a turban with an automatic rifle propped behind him."The blessed London raid was a slap in the face of the arrogant, crusader British rulers," Zawahri said."This glorious raid, like the others before it in New York, Washington and Madrid, has moved our battle right to the enemy's doorstep," he said, referring to the September 11, 2001 attacks in the United States and last year's bombing on Madrid trains which were blamed on al Qaeda."People of the crusader alliance, behold the disasters the policies of (US President George W) Bush and Blair will bring upon you," he said.British police said they would look into the videotape.A spokeswoman for London's Metropolitan Police said: "We are aware of the tape, we will consider it as part of our ongoing investigation." British Prime Minister Tony Blair's office refused to comment on the video.- AFP/Reuters/Kyodo/AP
Fire Rescue Quad-Rotor(Final Blog)
Fire Rescue Quad-Rotor(Final Blog)
Introduction-This is the 3rd and final blog post for this project. We have as far seen how the quad-rotor gets itself into an unknown world with a laser sensor and tries to get sense of the unknown world. As the blog progresses we will dive into the concepts behind the progress made during each milestone that is covered. Milestones covered during this project are-Milestones Covered:We were able to obtain an occupancy grid from the rviz for the given environment.Successfully controlled the Quad rotor all around gazebo world and mapped it on rviz through slam.The Quad-rotor was able to locate humans and fire(heat-zones) with blue and red cubes on the rviz. From the rviz, we extracted occupancy grid in one dimensional form.Converted the occupancy grid into 2-D.Filtered the noise from the obtained grid to make it useful.Implemented A star algorithm to get a shortest and safest path to the exit from the safe zone. OCCUPANCY GRIDAn occupancy grid is an output which we obtain from the rviz based on what the quadrotor had observed in the gazebo environment. It is nothing but a 1-D array of the environment it has observed once it has been taken through the entire course. This would be useful in making the quadrotor to perform specific functions as this is the environment in which the drone has realised its environment and not the gazebo one. But before we can take these values and perform further manipulation we need to filter out certain values of the grid.FILTERING OCCUPANCY GRID:The values if printed from what is saved in the occupancy grid we will be able to see a 1-D array which comprises of basically three values :Zero(0):-It depicts free space in the map.(Negative 1):-This is showing up in the array of value because of the fact that the Laser sensor which has been used to perform the SLAM module will have higher ranges than the environment in which it has been confined and these are representation of blocks which are beyond the environment and the quad-rotor is unaware of its possibilities whether it is free or occupied, So, technically it depicts unknown. (Numerical 100) :-This depicts that there is 100% probability of having an obstacle.Thus we need to filter out the values of -1 from the array as it will only make further complications in the processing of the map. We neglect -1 and convert the 1-D array into a 2-D array such that it represents the exact boundary of the environment. A star implementation:A star is one of the many available path finding algorithms which are available. The reason for choosing the A star algorithm over other algorithms is the fact that it gives quicker results as this can also consider diagonal path for movement and not only up and down movement. Thus we will be able to attain the shortest path in the quickest time period. But to implement the A star path we need two specific points between which the path is to be generated. One point would be the exit , so the other point should be within the environment . We should declare a point within the environment as the gathering point in the event of any catastrophic event such as Fire. Thus when we implement the A star algorithm we will obtain the safest and shortest path to the exit.FUTURE ENHANCEMENTS:There is a lot of opportunity for further enhancements in the project such as:Identifying sensor which would differentiate between obstacle fire and humans trappedOnce able to differentiate we could also be able to bring up markers in the rviz indicating the environment as it is to people who are viewing it from outside.Make the drone autonomous , that is once introduced to a new environment it must be able to move on its own and perform SLAM on its own. Final Comparison of Results-Initially we thought the quad-rotor as a global path planner such that it can sense the environment and output us a safe path to and fro the safe zone and exit and we were successful in achieving this goal.We were also successful in getting the unknown environment of the gazebo world on rviz along with humans and fire zones shown on the rviz with robots knowledge of them.We tried implementing a camera over the drone and tried to implement image recognition so as to differentiate between humans and other obstacles but we couldnt achieve it, although we didnt mention implementation of image recognition in our fundamental milestones. Instead we used basic lists for humans and heat zones and used programming algorithms to get the desired output.We wanted to have an algorithm and distinction system for the robot so as to make it more cognizant of its atmosphere and to predict the probability of danger to every human in its vision but we due to nonavailability of time we couldnt achieve this goal.Over-all if we look towards the progress of this project we can see that almost all the fundamental goals of this project are covered in the course of this project.
