The smart hardware is really smarter and more artificial. It is reported that the Apple Watch, which has received wide acclaim in the hardware market, has achieved excellent results in cutting into the medical field. According to the latest research, Apple Watch can now detect diabetes with an accuracy rate of 85%.
At the end of last year, there were reports that Apple intends to vigorously develop the use of Apple Watch in the medical field. Only a few months later, this smart watch has shown its strength. According to a recent study by health technology startup Cardiogram, Apple Watch is able to detect diabetes with an accuracy of 85%. The problem is that this diagnosis is only for users who have been diagnosed with diabetes.
In any case, this study shows that Apple Watch can indeed become a qualified medical accessory in the future. In the study, Cardiogram examined data from 14,000 Apple Watch users and used the watch's built-in heart rate sensor to determine that 462 of them had diabetes.
So how did they do this? According to a study conducted by the Framingham Heart Study in 2015, the heart rate of diabetic patients is different from that of healthy people. So in theory, Apple Watch's heart rate sensor can detect abnormal heart rhythms and identify people with diabetes.
Of course, since heart rate sensors are standard on many fitness wearables, this means they can have similar capabilities.
In addition, diabetes is by no means the only disease that can be detected by wearable devices. Cardiogram has previously used Apple Watch to identify heart rhythm abnormalities, and combined with their own AI algorithms, they achieved 97% high accuracy. At the same time, Apple Watch can detect sleep apnea and high blood pressure with high accuracy.
Cardiogram's team wanted to further study the practicality of Apple Watch (and other fitness wearables) in medical diagnostics, and they wanted to find more diseases that could be identified by heart rate sensors.
If these studies are successful, the health care industry may have an explosive development. After all, early detection is a key part of disease treatment, and it can also reduce the cost of treatment for patients.
Bitcoin mining machines are one way to obtain bitcoins. Bitcoin is an online virtual currency created by open-source peer-to-peer software. Instead of being issued by a specific currency institution, and produced by the massive computation of a specific algorithm, the Bitcoin economy uses a distributed database of nodes throughout the P2P network to identify and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin by producing a large number of coins.
Any computer can become a mining machine, but the returns will be low, and it may not mine a single bitcoin in a decade. Many companies have developed specialized Bitcoin mining machines with special mining chips that are tens or hundreds of times faster than normal computers.
Currency system by the user (the user through the key control wallet), trade (trade will be broadcast to the whole currency network) and miners (generated by competition calculation agreed on each node of the chain block, block chain is a distributed public authority books, contains the currency network of all the transactions happened)
Bitcoin miners manage the Bitcoin network by solving the problem of proof-of-work mechanisms with a certain amount of work -- confirming transactions and preventing double payments. Because hashing is irreversible, finding the number of random adjustments required to match is difficult, requiring a trial-and-error process that can predict the total number of times. This is where the proof-of-work mechanism comes into play. When a node finds a solution that matches the requirement, it can broadcast its result to the whole network. Other nodes can then receive the newly solved data block and check whether it matches the rule. If the other nodes calculate the hash value and find that the requirement (the operation goal required by Bitcoin) is satisfied, then the data block is valid and the other nodes accept the data block.
