World’s first single-panel antenna to simultaneously support multiple 5G communications

Figure 1: Configuration of equipment developed to communicate simultaneously with four users with one antenna panel. Credit: Fujitsu Fujitsu Laboratories Ltd. today announced the development of the world’s first equipment technology to enable simultaneous communications to four users with a single antenna panel in the 28-GHz band, in the world’s most compact structure. The equipment delivers high-speed communications in excess of 10 Gbps, as required by 5G mobile communication formats. The use of 5G is premised on deployment of base…

Artificial joint restores wrist-like movements to forearm amputees

An implant is placed into each of the two bones of the forearm — the ulna and radius — and then a wrist-like artificial joint acts as an interface between these two implants and the prosthetic hand. Credit: Biomechatronics and Neurorehabilitation Laboratory/Chalmers University of Technology A new artificial joint restores important wrist-like movements to forearm amputees, which could dramatically improve their quality of life. A group of researchers led by Max Ortiz Catalan, Associate Professor at Chalmers University of Technology,…

Online Payments with React + Square – Square Corner Blog – Medium

Create a custom payment form using React and Square There are a lot of ways to accept payments online. Wouldn’t it be nice to implement a single form that could accept as many payment methods as we want at a single time? Let’s take a look at implementing a custom payment form using Square and React. This form will enable us to take credit cards online, and give us support for Apple Pay, Google Pay, and Masterpass in a single payment…

The future of flight is now

Ion-propelled device. Credit: Case Western Reserve University Many experts agree the future of flight will rely on zero-emission and/or renewable energy technology. That is, aircraft will be propelled by ions—electrically charged molecules—that create thrust in their wake. But Northeast Ohio inventor Ethan Krauss says the technology is already here. In fact, he’s invented an aircraft that flies silently, with no moving parts, and no emissions. “People think this is something that we will do in the future,” he said.…

A Guide to Temperature Sensor Selection

In putting together any circuit for temperature detection, part of your job as a designer is keeping costs under control. This responsibility can and should influence your choice of a temperature sensor. Let the application requirements guide your selection and make the most affordable decision that meets all your needs for reliability, accuracy, and performance. Many practical considerations influence your sensor selection. Temperature Range Temperature range is one of the first matters to consider when picking out a temperature sensor.…

Materials that harvest heat and turn it into electricity could lead to more cost-effective devices

Credit: Dr Song Yun Cho, Korea Research Institute of Chemical Technology Scientists are getting closer to designing thermoelectric materials that efficiently harvest heat from the surrounding environment and convert it into electricity to power various devices and appliances, according to a review of the latest research in the journal Science and Technology of Advanced Materials. Devices made with these materials could avoid the need to recharge,…

New fingertip sensors to help veterans feel through their prosthetics

Credit: University of Colorado at Boulder Today’s prosthetic limbs are tools – literal attachments to the body. They help with the daily activities that impact quality of life, but they are not integrated into the user’s body like our intact limbs. That caveat presents a challenge for engineers, scientists and doctors – make a prosthetic hand that is just as capable as the one that was lost. The missing link? The sense of touch. Engineers at CU Boulder…

Engineering faculty member earns Inclusive Teaching Award

Assistant Professor of Electrical Engineering and Computer Science Fang Wang is looking to make MU classrooms more inclusive — and with her recent UM System Inclusive Teaching Award win, she’s on her way to achieving her goal. Fang Wang Prior to earning her doctorate from the University of Missouri and joining the faculty, Wang worked as a senior device modeling and characterization engineer at Motorola, Inc. and Freescale Semicondutor, Inc., before transitioning into software engineering in research and development at Ansys,…

Inferring Label Hierarchies with hLDA – Square Corner Blog – Medium

The Problem: Organizing Square Support Center Articles At Square, we get businesses up and running quickly. We also work hard to make sure sellers get their questions answered quickly. When Square sellers encounter a problem with a Square product, one of the first lines of defense is Square’s Support Center, which has hundreds of articles to help sellers find answers to their questions. Square’s Content team routinely adds articles to the Support Center. This set of articles has been growing organically…
