Toyota’s New Wireless Robot

Today, Toyota announced it’s new wireless robot called T-HR3. This humanoid sized robot can be controlled with a wireless remote with a 5G wireless connection and can be controlled for up to 6 miles.

This is how it works: the operator can control the robot through its hands, arm, and foot movement and can virtually see everything that the robot experiences. Pretty cool huh?

Currently, the T-HR3 is used to help doctors, people with disabilities, the elderly and anyone who needs it medically. The only issue at hand is what good it will do if it’s not on pilot because there would have to be someone ready to control it. Apparently, there is talk that these robots could eventually move on their own and that’s pretty scary.

New Wireless Service Provider? Introducing Google Fi

Back in 2015, Google came out with “Project Fi” which provided phone service, call/text, and internet. The only problem was that it was only capable with android phones. Now with the new Google Fi, any phone can be used with this new provider making it a direct competition with sprint, t-mobile, and other US carriers. All you have to do is download the app!

What makes this new addition to the cellphone provider market is that the prices are relatively in expensive – all with no contract. This includes unlimited call/text for $20 and $10 per gigabyte of data which makes bills not much more than $80 per month at most. The other nice thing about Google Fi is that you can switch between your wireless networks if they seem better at the moment of usage.

The only problem with Google’s new technology is that the coverage might not be anywhere as good as AT&T and Verizon. Therefore if you’re ever in a situation of emergency, you may not be able to reach anyone which would be very unfortunate.

News Briefings and Smart Speakers!

It is a no-brainer that new technological advancements are being implemented day by day. Hence, the question of whether we completely know our current devices or not still reigns. Focusing on the capabilities of voice-activated, internet-enabled speakers, they are still not completely smooth in some domains. News briefing is one such domain.

A new report from the Reuters Institute suggests that the institute’s survey finds that users simply aren’t enjoying the news briefings, and they’re taking a backseat to more concrete functions like information searches and immediate tasks. Moreover, the fact that there are so many features which are aimed at solving this particular problem being used by tech giants like Google has still not amounted to much. For example, Alexa has a bunch of different Flash Briefings designed to give you a quick rundown of everything that’s happened. Google Home has a whole set of custom news commands which allows users to skim through different stories or find stories on particular topics. A lot of time and energy from tech and media companies alike went into making this work, but for whatever reason, it just never came together.

The Reuters report gives us a few hints about why that is. Sometimes the reports would be outdated or mangled through awkward text-to-speech programs. Other reports were too long which caused mental fatigue for some users. Among other users, the audio-only interface made it hard to keep track of whom they were listening to.

But the biggest problem is that we simply don’t know what we want. Though the fact that smart speakers aren’t radios stands true, there are some features which are handled with great efficiency. For example, these smart assistants are great at handling specific questions like “Alexa, what’s the capital of US?” — but walking through the most important events of the day is a different thing. It may be that smart speakers are just not ready for it!

Feel free to share your opinions or ask any question!

Office Chair that cancels noise

Have you ever tried to get work done but were distracted by the noise around you?  The scientists at the Budapest University of Technology and Economics have created an office chair that can cancel out any disturbing noises in the room.  A research film showed that an open office can lose up to 86 minutes of productivity a day from distractions.  The noises can be as simple as the constant humming of machinery or computers.  There have been attempts to combat this in the past, with the example of noise cancelling headphones, but most are uncomfortable to wear for long hours.

These scientists customized a popular gaming chair by attaching flexible error microphones to the headrest of the chair.  Their design is based on the feed-forward control system.  Microphones are placed throughout the room and receive sound waves that send out reference signals, generating signals that make loudspeakers start the cancelling noise.

The scientists tested out how many microphones should be used throughout the room in a classroom.  they also performed computer simulations to see where the error microphones should be placed on the chair.  The microphone should be placed in a certain position where the head will be, so a dummy head with a sound level monitor was placed in the chair to test this.  The chair was effective at cancelling noises of frequencies ranging from 200 to 800 Hz, and the typical hearing range of a human is 20 Hz to 20 kHz. Noises created by things like electric motors, fans or other machines have very predictable frequencies which made it easier to design the chair.  The chair can also cancel random noises about 1 kHz, however the chair couldn’t cancel random noise below 300 Hz.

These chairs could be very important when looking to improve productivity in a work environment.  Some minor modifications to increase the level of noise cancellation could be made, but the idea itself is very strong.

market of iwatch

The market for iWatch is a wearable tech-computing market. Smartwatches are a combination of traditional watch and high-tech. iWatch is also a representative of the internet of things since the network of physical devices embedded with electronics, software which enables connect and exchange data, resulting in efficiency improvements, economic benefits, and reduced human exertions.

We can find that battery life is one of the important factors that smartwatch companies should focus on, From battery life and price these two most significant perspectives, the iWatch does not show great competitive advantages. The battery life is quite short compare with other smart watches and the price is the second highest.

For Samsung, which is the biggest competitor its watches can work independently and there is no need to connect to other devices through Bluetooth. However, its software is a bland look.

From our observation, those who use the apple watch have several characteristics. We summarize these characteristics into 4 categories. Geographically speaking, there is no limit. The users come from all over the world. In terms of demographics, the users are adults around 18 to 45 years old and these people or their family members usually earn a middle to high income. In terms of psychographic, the users often pursue a healthy, productive lifestyle, they involve in many physical activities and they have a desire to keep a good pace with their schedules. They also like to get instant access to any messages and notifications. Also, the users mostly like to seek a device that brings substantial amounts of benefits to them and a large part of them are loyal to the Apple brand.

Phone App Becomes a Valuable Tool to Save Lives

STEMI, short form for ST-Elevation Myocardial Infarction, is a most serious and deadly form of heart attack. At the time of illness, the artery is completely blocked. The block of major artery will stop the transportation of oxygen and blood with nutrient to heart muscle. Under this case, the sooner we get the artery back to open, the better chance patient get back to healthy state. Usually, doctor would use a standard 12-lead electrocardiogram(ECG) to diagnose heart attacks. With AliverCor app, everything can speed up since app is more accessible than equipment in the hospital. But how effective is the app in distinguish STEMI?

In study,  204 patients with chest pain was under the examine from both standard 12-lead ECG and an ECG from AliveCor app. AliverCor app simply working with a smartphone and two-wire attachment. According to the result, app did successfully and effectively in distinguish STEMI patient with high sensitivity compared to the traditional method. The traditional 12-lead ECG can accurately diagnose heart attack since heart attack happens in different part of the heart and each lead monitors different part. For AliverCor app, the two wire leads can moved around the body to trace the movement of 12 parts.

This finding is crucial from two perspective. First of all, for patient who have never experienced STEMI before won’t take chest pain seriously and may miss the golden time for treatment. With this app, patient can detect this problem in time and rush to hospital to receive treatment.

Secondly, the price of the app and two-wire lead is low and is more accessible to anyone who have smartphone. The low price also makes it possible for this technique to spread to third world countries and benefit more people.

Test and feelings about my iphone xs max

After using iPhone XS Max for two months, my friends and I start to do some research and find the differences and advantages of the screen of the xs max.

Our argument about the size of a smartphone screen seems final to have reached a conclusion in 2018. Even if you’re as stubborn as apple, there’s no denying the allure of a big screen. This year, manufacturers have finally put aside their one-handed obsession, with smartphones generally having screens larger than 6 inches after a full screen.

So it’s fitting that the 6.5-inch iPhone XS Max, which is 6.46-inch in rounded corners, has the same OLED screen, which has been upgraded in order to maintain the same 458ppi resolution as last year’s 5.8-inch iPhone X. So visually, the screen is about as delicate as the iPhone X, and at the same level as this year’s iPhone XS, which is only inferior in screen size.

Currently, the only devices that surpass the iPhone XS Max screen indicator are the old rivals Samsung Galaxy Note 9 and S9 series, which have a color accuracy of 0.5 JNCD (smaller is better), a maximum brightness of 710nits, and chicken blood mode even exceeding 1,000 nits. But that’s only a literal difference for the average user, since the iPhone XS Max is, by all accounts, a top-of-the-line OLED screen that, like the Note 9, represents the highest level of the current smartphone industry.

techniques in my hotel in las vegas.

This week, Thanksgiving Day, my boyfriend and I spent in Las Vegas. We booked the most famous hotel wynn encore, the hotel room is very attractive to me, it is a very simple and technical room. On the first day we arrived, the curtain opened automatically when I stepped into the door. I believe this is already a very mature technology. There is a remote control on the coffee table to remotely control the switch of the curtain. This made me think of IOT. There is also an automatic thermostatic bath in the bathroom. We can control it on a small machine on the bedside table. IOT is everywhere in our lives, and it is everywhere in big cities like Las Vegas.

BI Intelligence estimates that there will be more than 24 billion iot devices on earth by 2020, about four per person. When we get close to this stage, $6 billion will flow into iot solutions, including application development, device hardware, system integration, data storage, and so on. Yet these investments will yield $13 trillion in benefits in 2025.

 

Dead Celebrity Holograms

Modern holograms are a confusing concept. They’re not quite the same as what we’ve come to expect from movies.

Six years ago, the “hologram” that created Tupac Shakur at Coachella wasn’t even a hologram at all, but rather something known as “Pepper’s Ghost,” which used glass and tricks of the light to make a fabricated video seem 3D. That performance seemed new and innovative, since “Tupac” reacted to the crowd’s applause and the actions of the others on stage, but much of that was pre-determined and pre-programmed. “Pepper’s Ghost” itself is a technique that was invented 150 years ago.

There are three big companies in the field of holographic dead celebrities (Hologram USA, Pulse Evolution, and Base Hologram), and all of them seem to approach the creation of holograms in a slightly different way. They also have tremendous legal trouble even gaining the rights to use posthumous celebrities’ mannerisms and character.

None of the three companies is keen to give away its secrets, either. Facial tracking, high-frequency animation, and CGI are likely and in some cases confirmed. In the case of recreating Amy Winehouse, pictures of her from many different angles and longer videos of her talking are being stitched together in a meticulous process. 3D scans can be used on celebrities available (read: alive) to make the hologram happen. Chatbots and AI technology can also be used to generate how the “performers” ad lib and talk.

No matter how the celebrity is created, it seems very unlikely that it’s viewable from a variety of different angles, or able to even move around much. Videos of the holographic act are taken from one angle — straight forward. Despite the chatbots and AI that can be used, the talking ability of the hologram is limited. It can’t react to the crowd any more than the programmers can predict applause. “Thanks for coming,” is pretty much it.

There are other methods of creating holograms, like Light Fields Lab’s work with light fields, but of course their methods are under lock and key considering they plan on being ready to sell services/products in 2020. However, they’re going a different route than that of dead celebrities, looking towards integrating their work into movie theaters and casinos.

Holograms have been a point of interest in culture, given their depiction in movies. Currently the real thing isn’t exactly stacking up, and it begs the question of if we’ll ever see a version quite like Princess Leia’s.

Sensors put in fish to monitor stress levels

A new study that researchers put together at the Swedish University of Agricultural Sciences includes implanting bio-loggers into farmed rainbow trout to monitor them in the wild.  The researchers measured the stress hormone cortisol before and after introducing stressors to see how their heart rate is affected when put in a stressful situation.

The bio-loggers implanted are small, bullet shaped sensors that are about 13 cm or 1.5 inches long.  Their function is to measure heart rate and temperature from inside an animals for 18 months.  Most researchers would go about this study by looking at fish when taken out of water, but this is unsustainable because their research can only last a few minutes and the fish will eventually die. The purpose of monitoring stress in farmed animals is related to their health and to ensure quality production.  Stress can negatively affect the quality of final products in the category of taste and texture.

To implant the bio-loggers in the fish, a preliminary study was required to fine the best position for the sensor.  It was found that the optimal position for the sensors was when it was placed horizontally between the two front fins, pointing towards the head.  the sensors were put into 20 fish and placed in a net cage.  After 4 days, they noticed that the fish had fully recovered from the stress of the implantation surgery.

The results were very interesting. “The researchers then took measurements of heart rate and cortisol over a 2 day period. The fish were recorded when they were swimming normally around the sea cage, experiencing a moderate increase in the density of fish, an additional increase in density, after being scooped into a transport boat, in the boat while moving and after it stopped, after being moved to the slaughterhouse holding tank, while in the holding tank right before slaughter, and while they were being euthanized with CO2.” (Erica Curles).

An increase in heart rate was shown during stressful events.  Their stress levels decreased when being loaded into the boat when it wasn’t moving.  They believe that this was due to the oxygen level being low during those times which causes fish to decrease their heart rate.  When the oxygen was increased, their heart rates also increased.  These events were stressful to the fish and showed that the holding time before slaughter was not long enough for fish to recover to normal levels.

This technology is an important thing for farmers so that they can increase the quality of their products and become more popular.  They need to pay attention to recovery times to produce the best quality and most relaxed fish.
