Nice.

Engineers at the University of Washington (UW) have devised a new method of wireless communication that converts Bluetooth transmission from mobile devices into Wi-Fi signals. Using this “interscatter” communications technology allows medical devices and implants with limited power sources to gain the ability to send data using low-power Wi-Fi signals to smartphones and smartwatches.

The UW team previously described the technique of “backscattering” ambient RF signals — repurposing existing RF signals in the environment — to enable device-to-device communication without the need for onboard power sources. Now, the team builds on that prior research to introduce “interscattering,” the inter-technology, over-the-air conversion of Bluetooth signals to create Wi-Fi transmissions.

The researchers wrote in a paper that novel medical devices, such as smart contact lenses and neural implants, currently have power constraints that limit their ability to generate Wi-Fi, Bluetooth, or ZigBee transmissions to communicate with smartphones, watches, and tablets. To overcome this, the researchers suggest an interscaterring communication system.

A novel device architecture is used to simultaneously achieve extremely high internal quantum efficiencies, low drive voltages, and long lifetimes, at practical luminance levels.

An LED with an emissive organic thin film sandwiched between the anode and cathode is known as an organic-LED (OLED). The emission mechanism of an OLED is superficially similar to that of a standard LED, i.e., holes and electrons are injected from the anode and cathode, respectively, and these carriers recombine to form excited states (excitons) that lead to light emission.1 In recent years, smartphones and TVs with OLED displays have rapidly become widespread because OLEDs provide high contrast, a wide color gamut, light weight, thinness, and flexibility for the displays. OLEDs also have great potential for the creation of new lighting applications.2 The high power consumption and short lifetime of OLEDs, however, remain key issues.

I have share my own risks on BMI a while back especially that which is connected (net, cloud, etc.)

brain malware 1Short Bytes: For a moment, forget computer and smartphone malware. There’s even a bigger danger in town in the form of brain malware. By exploiting brain-computer interfaces (BCI) being used in medical and gaming applications, hackers can read your private and sensitive data. Recently, a team of researchers from the University of Washington shed more light on the subject, demanding a policy-oriented regulation on BCIs.

Researchers at Queen’s University Belfast and ETH Zurich, Switzerland, have created a new theoretical framework which could help physicists and device engineers design better optoelectronics, leading to less heat generation and power consumption in electronic devices which source, detect, and control light.

Speaking about the research, which enables scientists and engineers to quantify how transparent a 2D material is to an electrostatic field, Dr Elton Santos from the Atomistic Simulation Research Centre at Queen’s, said: “In our paper we have developed a theoretical framework that predicts and quantifies the degree of ‘transparency’ up to the limit of one-atom-thick, 2D materials, to an electrostatic field.

“Imagine we can change the transparency of a material just using an electric bias, e.g. get darker or brighter at will. What kind of implications would this have, for instance, in mobile phone technologies? This was the first question we asked ourselves. We realised that this would allow the microscopic control over the distribution of charged carriers in a bulk semiconductor (e.g. traditional Si microchips) in a nonlinear manner. This will help physicists and device engineers to design better quantum capacitors, an array of subatomic power storage components capable to keep high energy densities, for instance, in batteries, and vertical transistors, leading to next-generation optoelectronics with lower power consumption and dissipation of heat (cold devices), and better performance. In other words, smarter smart phones.”

Starting later this month, Uber will allow customers in downtown Pittsburgh to summon self-driving cars from their phones, crossing an important milestone that no automotive or technology company has yet achieved. Google, widely regarded as the leader in the field, has been testing its fleet for several years, and Tesla Motors offers Autopilot, essentially a souped-up cruise control that drives the car on the highway. Earlier this week, Ford announced plans for an autonomous ride-sharing service. But none of these companies has yet brought a self-driving car-sharing service to market.

Uber’s Pittsburgh fleet, which will be supervised by humans in the driver’s seat for the time being, consists of specially modified Volvo XC90 sport-utility vehicles outfitted with dozens of sensors that use cameras, lasers, radar, and GPS receivers. Volvo Cars has so far delivered a handful of vehicles out of a total of 100 due by the end of the year. The two companies signed a pact earlier this year to spend $300 million to develop a fully autonomous car that will be ready for the road by 2021.

The Volvo deal isn’t exclusive; Uber plans to partner with other automakers as it races to recruit more engineers. In July the company reached an agreement to buy Otto, a 91-employee driverless truck startup that was founded earlier this year and includes engineers from a number of high-profile tech companies attempting to bring driverless cars to market, including Google, Apple, and Tesla. Uber declined to disclose the terms of the arrangement, but a person familiar with the deal says that if targets are met, it would be worth 1 percent of Uber’s most recent valuation. That would imply a price of about $680 million. Otto’s current employees will also collectively receive 20 percent of any profits Uber earns from building an autonomous trucking business.

Hmmmm;

It is an old issue, but with a new revelation by the most credible insider source to date. Recently, I was contacted by Dr. Paul Batcho. Batcho is a former DARPA senior scientist who worked at Los Alamos and held a top secret security clearance. In short, Batcho asserts that clandestine forces are purposely engaging in “acts of terrorism” against the general public through emission of dangerous frequencies from cell phone and microwave towers in the St. Petersburg/Orlando/ Tampa, Florida area.

Before launching into a revelation of the stunning claims presented to me by Dr. Batcho, let’s establish his crediblity as a reliable witness.

Below is the publicly available professional background of Dr. Paul Batcho:

I do wish Tim a lot of luck.

Going by the data from all quarters, the iPhone maker isn’t in the best of shapes when it comes to the China market. It’s the slow down in the China market that seemingly compelled Tim Cook to look at India with hopes. After all, never before has India got mentioned in Apple’s earnings call, and this was also the first time that Tim Cook visited India to make a slew of announcements. Today, we have the first (in Asia) R&D centre for Maps and an incubator in Bengaluru, along other announcements.

If you were thinking that India is finally becoming the ‘apple’ of Tim Cook’s eyes, then the latest announcements will tell you otherwise. Tim Cook has announced that Apple will have an R&D centre in China by the end of the year. And why not, Apple believes that we are where China was 6–7 years ago. But that’s not all, the company may have also miffed officials with its R&D in India announcements.

Tim Cook’s latest visit, and second in the past four months, has led to the announcement of a new R&D center, which is said to be first of its kind in Asia. His previous visit to China was followed by a ‘surprise’ India visit wherein he announced the R&D centre for Maps. This has also led many to believe that Cook’s announcement for China is rather late. But what’s caught everyone’s attention is how Cook called for a media briefing to discuss the new center.
