What Is the Difference Between System Image and System Repair Disc?

"Create a system repair disc". should repair your computer without you losing your personal files, but still best to back up just in case. "Create a system image" will take your computer back to exactly as it was the day you bought it. It's best to burn the two options to discs, but you will likely have the option to restore factory settings without using the discs. Still best to burn the factory image though in case of hard drive failure, then you will always have the restore discs to install Windows to your new hard drive.

2. Why is home heating wiring so low tech? [closed]

why central heating systems are not more modernBecause the established systems like Honeywell Y-plan or S-plan have many benefits ...So far as I can tell, systems like Nest only have significant benefit if your lifestyle is erratic and you need to remotely instruct your house to keep cold to save money.Why is not there a central controllerThere seems to be a trend where more of the functionality is incorporated into the boiler. For example it is becoming more common for the boiler to control the pump so that it can run-on after the boiler stops, thus removing residual heat from the boiler.Of course, systems like Nest do not change much of the above, they are designed to slot into those types of system. Often they function as a combined programmer and room-thermostat replacement with additional features.Random example showing industry standard backplate interoperability:

3. Would there be any negative consequences from Hurricane Dorian not making landfall in Florida?

The course of Dorian is unpredictable but shows a coastal tract with no landfall in Florida, however a hurricane of this magnitude (4) has a large funnel phenomena. That said it can cause severe damage to eastern coastal areas due to heavy rains, winds and flooding from high water level. I am deeply concerned about potential disruption in transportation, damage from the trees, roofs, lanais, and businesses, food and health care system. It all could be very catastrophic and extremely dangerous.Would there be any negative consequences from Hurricane Dorian not making landfall in Florida?

4. Does it hurt when you have to push the poop out, and it's really hard?

u need some whole grain in ur system asap

5. Why do they install big cooling stacks around nuclear reactors and coal-fired generating plants?

The electric power plants (any technology that generates heat to make steam to turn the turbine) has cooling towers, unless it takes in and discharges directly to a river, large lake or sea. The cooling towers are used to efficiently cool the water that is condensed off of the steam turbine (or cooling system of the Nuke reactor), so that they do not use a lot of water - it is recycled. When the hot water evaporates, it cools off. Similar systems are used even on office buildings and schools, not just in power plants

6. How can I save on my heating bills? Part II?

For where you are at and the temperature range you need to look at two things which are easy. What is the construction of your windows (single pane, metal frame) that may allow a higher temperature transfer and a quick peak into the attic to look at the insulation. Most home that are older than 18 years can use a good shot of 10 to 12" back into the attic space. The insulation should be 8 plus inches above the rafters. Insulation settles over time loosing its "R-Value" and in turn it costs more to keep your home comfortable. Other things would require a service person to come to your home for inspection. Ex; Dirty a/c coil restricting air flow of your central heating and cooling system

Analysis and Introduction of Mobile Phone Application Integrated into Vehicle System
Analysis and Introduction of Mobile Phone Application Integrated into Vehicle System
For motor vehicle drivers, they always face various obstacles if they want to obtain all kinds of information and entertainment content through smartphone applications. But now, the "demolition action" against this obstacle is finally in high gear.Facing the continuous complaints of consumers and the new income generation prospects, automobile manufacturers and major enterprises in the smartphone and application market are making full use of their own software and hardware to eliminate various obstacles that hinder the perfect integration of automobile display screen and application content.Now a number of new products have emerged, which makes it very convenient for the electronic equipment of the car center console to use the data provided by the Smartphone Application, so as to obtain the information of real-time traffic map, parking lot entrance and weather forecast."This year is a turning point," said Thilo Koslowski, an on-board technology analyst at Gartner, an American market research company. "There has been a lot of discussion about on-board applications before, but from 2014, this revolution will really take place."GM has cooperated with Pandora to integrate this streaming music service on the center console of most Chevrolet, Buick and Cadillac models. Honda also integrated AHA radio into its own car. If you buy the 2014 Mercedes Benz, you will find the tunein Internet broadcasting application on the center console, which can listen to broadcasts around the world through your smartphone. Next year, GM and Audi will also launch models equipped with 4G Internet service, so that drivers can even completely abandon smartphones.BMW is also developing an app store in the way of Apple iTunes to provide users with their own car applications. The app store is expected to open later this yearLaunched, and will land in the United States in 2015.New selling pointFor automobile manufacturers, electronic and communication functions have become key selling points. For many buyers, this is even more important than engine power or handling, especially for young consumers and first-time car buyers. "This is a major transformation of the entire industry in the digital environment," said Mathias Haller, Audi's chief infotainment system architect.We can call today's trend "Automotive Application 2.0". The new models manufactured in the past few years have helped users realize hands-free mobile phone calls with technologies such as USB interface, microphone and Bluetooth. Some models can even listen to podcasts or streaming music on smartphones. However, the interface of the first generation products is usually bulky, which may distract the driver's attention and cause danger. Because the voice commands are confusing, the driver has to pick up the mobile phone and use his fingers to operate the screen to select songs, view addresses or enter destination information.But that will soon change. At the New York International Auto Show last month, a car displayed by Mercedes Benz was equipped with an on-board infotainment system using apple Carplay system. As like as two peas, the interface and feel of the system are exactly the same as iPhone. The icon on the car display is exactly the same as the iPhone icon."The fewer things the driver needs to learn, the higher the safety," said Carl MOS, director of online information and entertainment of Mercedes Benz. Moss said that the system will be assembled into Mercedes Benz by the end of this year.Christine Bickley, a computer expert in New Jersey, found that when she recently drove home with the 2014 Kia Freddy, the car's UVO infotainment system would automatically synchronize with her Samsung Galaxy mobile phone, and then play streaming music in the mobile phone application through the car. In all operations, you don't need to leave your hand off the steering wheel, and your eyes can always stare at the road."That's cool. As soon as I get into the car, Bluetooth connects automatically. There's a button on the steering wheel to change playlists. I don't need to touch my cell phone - it's always in my bag," Bickley said. The singer, song and playlist information originally displayed on the mobile phone screen will be projected onto the screen of the center console."When I bought the car, I immediately called my friends and asked them to come and see it," Bickley said.Great potentialMobile technology providers and carmakers are still wary of each other, but they will benefit a lot if they can attract more consumers like Bickley.Security experts also hope that the new electronic devices in the center console can simplify the operation mode with the help of smart phones and reduce the dispersion of drivers' energy. Adrian Lund, President of the Insurance Institute for highway safety, said that early studies had shown that such technologies would at least not lead to further distraction. Although drivers can do more things with smart phones, they can "keep their eyes on the road and hands on the steering wheel" when using these functions because the operation is simpler."Drivers don't seem to be distracted by technologies as before," Lund said.Streaming music and navigation applications are just the beginning, and people will soon be able to achieve more functions through cars. Ford has demonstrated a feature that can order pizza from the nearest Domino's store through the application in the company's car infotainment system. Recently, car manufacturers have also begun to allow software developers to directly obtain data on the car itself, such as fuel consumption. Developers even envisage using applications to record the fuel consumption of each journey, and even let relatives and friends view their own data to understand each other's driving efficiency.
Select the Converter According to the System and Technology
Select the Converter According to the System and Technology
How do you decide which ADC technology to use in your application before you conduct a thorough system evaluation? You may prefer SAR converters (sar-adcs) because you think they are easy to use and faster than others Δ-Σ The converter should be faster. Second, you may choose to use one ΔΣ Converters, because you feel that although they are slower, they have better accuracy. Or without thinking about it at all, you may choose the ADC you often use. When selecting a converter, you usually make some decisions about the converter selection based on the significant digits (ENOB), accuracy, repeat positioning accuracy (noise), and output data rate. Your assumption may be that sar-adc uses medium output speed to produce accurate output, while DS converter uses lower output data rate to produce lower noise output signal. These assumptions may no longer guide you to choose between sar-adc and ds-adc. Think about how to change your design paradigm - shift your attention from a single device to the entire system. You will find that both ADC architectures may be suitable for a specific application. For example, if you know the system ENOB, an analog gain stage combined with sar-adc can match the performance of a high-speed DS converter. The system evaluation includes checking the system sampling speed (a detailed system accuracy analysis) and comparing the repeat positioning accuracy (noise level) performance of your system. Some problems affecting the sampling speed of the system are the selection of single clock frequency and the time allowed for the analog components to completely stabilize before conversion. In terms of system accuracy, you can compare the DC performance characteristics with the overall unadjustable error (Tue) quality factor. Repeat positioning accuracy is different from accuracy evaluation. It defines the consistency between the value obtained from one conversion and its next repetition. With repetitive positioning accuracy, you can combine the noise performance of signal link devices according to the effective resolution (ER). In the next article, we will study some specific differences between 12 bit SAR and multiplexed PGA (pga-sar) and 24 bit multiplexed DS converter. The gain range (analog or digital) of all systems is 1 to 128 V / V, and the supply voltage is 5V.When we study the accuracy and repeat positioning accuracy of these two systems, we can use table 1 as a starting point. In Table 1, the system gain ranges from 1 to 128. The second column of the table shows the full scale range (FSR) of the ideal system, which is the equivalent input (RTI) of the system. Finally, the system least significant bit (LSB, column 3 of the table) is equal to the FSR of the system divided by the number of system codes (4096).STM32/STM8STMicroelectronics / St / STM
Conventional Field Measurement Scheme and Purpose of Digital TV System
Conventional Field Measurement Scheme and Purpose of Digital TV System
This paper introduces some conventional field measurement schemes and purposes of digital TV system. Its working range includes receiving, demodulating and restoring transmitted data. The test of digital TV often focuses on several specific aspects, and the test scheme focuses on the following objectives.(1) Determine the environment variable and its minimum variable range.(2) Measure the coverage corresponding to the actual service.(3) Collect useful data to improve the performance of digital TV system.1. Classification of field surveyThe ad Hok broadcasting team defines four reception modes: fixed reception, portable, walking and mobile reception.(1) Fixed reception refers to reception by a fixed antenna and receiver.(2) Portable receiving is defined as the receiver can be moved from one place to another. It uses a set of fully equipped antennas for receiving, but it is already fixed when receiving.(3) Walking receiving is defined as receiving at low speed, with speed ≤ 5 kph (3.1 mph).(4) Mobile reception refers to receiving at high speed, generally > 5 kph (3.1 mph).According to four different receiving modes, the field measurement also has four aspects, as shown in Table 1.This paper mainly describes the outdoor reception, and the field test is mainly divided into the following aspects:(1) Coverage test.The meaning of coverage is to determine that the actual electromagnetic intensity reaches a specified index. Generally, coverage measurement has two purposes: the first is to detect the function of transmitting antenna; The second is to provide auxiliary data for transmission algorithms in different terrain for frequency band planning and estimation of potential interference.These test schemes first place the antenna at a place about 10 m above the ground, then correct the antenna to a standard dipole to verify its coverage and the transmission mode of the transmitting antenna, and provide measured data to develop transmission algorithms based on these factors in the allocated frequency band.(2) Service test.Service test, also known as acceptability test, is defined as the minimum condition for testing that digital TV signals can be correctly received and decoded in a variety of practical environments.Service testing usually connects the receiver to a data recording device, and then uses the latter to obtain signal level, edge threshold, bit error rate, adaptive equalization parameters and other information. These results are obtained by testing different times with various antennas. Generally, they are not repeatable in formal tests.(3) Obtain channel characteristics.Capturing channel characteristics has special significance. This paper refers to obtaining channel parameters by using specific fixed or mobile antennas at a specific time and place and measuring with known signals. The influence of channel on the known signal includes the change of signal level, impulse noise, boundary interference and multipath effect.

Design of Rainwater Detection System Based on Arduino
Design of Rainwater Detection System Based on Arduino
By using Arduino development board and rain sensor connection, a simple rain detection system can be easily made. The sensor will detect any rainfall and the Arduino development board will sense it and perform the required operations. Such a system can be used in many different fields, such as agriculture and automobile. Rainfall detection can be used to automatically adjust the irrigation process. Moreover, continuous rainfall data can help farmers use the intelligent system to automatically water crops only when needed. Similarly, in the automotive field, the wiper can be fully automated by using the rain detection system. Moreover, the home automation system can also use the rain detection function to automatically close the windows and adjust the room temperature. In this article, we will use Arduino and buzzer to make a simple rain sensor. You can then make whatever you want based on this setting. In addition, please note that the rain sensor module is also called raindrop sensor or rain sensor according to the use, but in this paper, they all refer to the same sensor and the working principle is the same.Materials required● Arduino uno development board● rain sensor● buzzer● bread board● connecting wiresrain sensor The rainfall detection module consists of two circuit boards, namely, the rainfall sensor circuit board and the control board.The rain sensor circuit board module (rain sensor) consists of two copper wires, which are designed so that they can provide high resistance to the power supply voltage under dry conditions, and the output voltage of the module is 5V. With the increase of humidity on the circuit board, the resistance of the module decreases gradually. As the resistance decreases, the output voltage will also decrease relative to the humidity on the module. The rain sensor circuit board module consists of two pins for connection to the control board, as shown below.The control board module controls sensitivity and converts analog output to digital output. If the analog value is lower than the threshold of the control board, the output is low level; If the analog value is higher than the threshold, the output is digital high. For comparison and conversion, LM393 operational amplifier comparator is used. Operational amplifier comparator is an interesting circuit that can be used to compare two different voltage values.As shown below, the rainfall control module consists of four pins for connecting Arduino, namely VCC, GND, d0 and A0, and the other two pins are used to connect the rainfall sensor circuit board module. In short, the rain sensor circuit board module detects rain, and the control board module is used to control sensitivity and convert analog values into digital values.Working principle of rain sensorThe working principle of the rain sensor module is easy to understand. During sunny days, because the module is dry, it has a high resistance to the power supply voltage. The voltage is 5V on the output pin of the module. If read by the analog pin of Arduino, this 5V reads 1023. During rain, rain will increase the humidity of the rain sensor module circuit board, resulting in a decrease in resistance. As the resistance decreases, the output voltage begins to decrease.When the rain sensor module is completely wet and the resistance provided by it is the smallest, the output voltage will be as low as possible (about 0). If read by the analog pin of Arduino, this 0V will be read as a value of 0. If the module is partially wet, the output of the rain panel module will depend on the resistance it provides. If the output of the resistor supplied through the rain shield module is 3V, the analog value read will be 613. The formula for finding ADC can be obtained by the following formula: ADC = (analog voltage value x 1023) / 5. By using this formula, you can convert any analog voltage to an Arduino analog read value.Circuit diagramThe following circuit diagram shows the circuit connection between Arduino and rain sensor.The rain sensor module shown in the circuit diagram is connected to the control board. The VCC pin of the control board is connected to the 5V power supply. The ground pin is grounded. If necessary, the D0 pin can be connected to any digital pin of Arduino, and the pin must be declared as an input pin in the program. Since d0 pin outputs high and low level signals, we cannot obtain the exact output voltage value of d0 pin. If the output pin exceeds the threshold voltage, the control module can monitor the change of the output. Even if the output voltage in the rain sensor module changes a little, we need to operate the buzzer. For these reasons, we use the A0 pin and connect it to the analog pin of Arduino, which makes it easy to monitor output changes. The buzzer can be connected to any digital pin of Arduino. If the buzzer requires more than 5V, try using relay circuits or transistors.Code descriptionThe Arduino code of the rain sensor is written using the Arduino ide. The complete code of the project is given at the end of this article.#define rainfall A0#define buzzer 5int value;int set=10;Define pin A0 as raincall, pin 5 as buzzer, declare variables "value" and "set" as integers, and set its variable set value to 10. You can change this value according to the actual situation. If you want to start the buzzer even if it rains very little, set the variable value to the minimum value.void setup() Serial.begin(9600);pinMode(buzzer,OUTPUT);pinMode(rainfall,INPUT);Initialize the serial communication, set the buzzer as the output pin and the raincall pin as the input pin.void loop() value = analogRead(rainfall);Serial.println(value);value = map(value,0,1023,225,0);In the loop function, the function analysisread reads the value of the rain sensor. Serial.println (value) prints the value on the serial port monitor, which is very helpful in debugging. The map function maps the value of the rain sensor on the output pin and assigns a value to the variable, ranging from 0 to 225.if(value>=set)Serial.println("rain detected");digitalWrite(buzzer,HIGH);If the read sensor value is greater than the set value, the program enters the cycle, prints a message on the serial port monitor and turns on the buzzerelsedigitalWrite(buzzer, LOW);Only when the value is less than the set value, the program enters the else function. When the set value is greater than the value of the sensor, the buzzer will be turned off, indicating that there is no rain.Work of rainwater detection system based on ArduinoThe working mode of the system is: when it rains, the rain acts as a trigger to trigger the buzzer. In the Arduino code of the raindrop sensor, we define pin 5 as the buzzer and A0 as the raindrop sensor pin.This is one of many application scenarios of rain sensor, and the same principle will be seen in wiper, other home automation, agricultural departments, etc. I hope you understand the project and like to make it.Editing: hfy
Build an AR / VR Software Ecosystem, and the next Generation IPhone Will Be Equipped with a TOF Came
Build an AR / VR Software Ecosystem, and the next Generation IPhone Will Be Equipped with a TOF Came
Although it is reported that Apple may cancel the development of augmented reality (AR) glasses, Apple's interest in Ar / VR software and ecosystem construction has not decreased.Recently, it is reported from the supply chain that Apple has asked its supply chain partners to provide VCSEL vertical cavity surface emitting laser components for the rear TOF camera lens of its mobile device to be released in 2020. The 2020 iPhone will include a rear camera with TOF components, which will greatly improve the AR experience.It is estimated that Apple's highlight will be in 2020. First, 5g iPhone will be officially launched, and A14 processor will adopt TSMC's most advanced 5nm process technology. Second, the face ID structured light scheme will continue to be used until 2020. Third, lumentum recently received an instruction from apple and hopes to mass produce VCSEL components for post lens TOF by the end of 2019.For the supply chain, apple, TSMC, lumentum and other companies have never made public comments on market forecasts.Although it is said that Apple may cancel the production plan of AR glasses, AR glasses are mainly based on the iPhone and iPad. Meanwhile, Apple has updated the software of AR ecosystem in WWDC 2019, including arkit3 with motion capture, which will make the single lens native induction camera have stronger functions through people occlusion, Ar virtual objects can appear in front of and behind humans, and the front lens can track three faces, which are helpful to develop AR applications with better experience.Apple's face ID module is indeed about two years ahead of the industry, and its performance potential is basically much higher than the current face recognition function only. The original design of face ID includes various AR / VR applications for rear lens.Relevant personnel recalled that at the beginning, for the mass production of iPhone x 3D sensing module, the leading manufacturer of Apple's supply chain in Taiwan, the big boss sat in the production line supervision and worked hard to complete the hard battle expected by apple. Many first-line personnel who worked hard at that time were impressed.However, many relevant personnel believe that the key lies in the application of AR / VR software and ecosystem, which is the development direction of Apple's combination of software and hardware, and can also give full play to 3D sensing functions such as face ID and TOF.
