Handheld 3D skin printer comes out, or the best laser engraver?

The Physicist Organization Network reported on the 7th that researchers at the University of Toronto in Canada have developed a hand-held portable 3D skin printer that can print multiple layers of skin tissue to cover and heal deep wounds. This is the first device that can form, accumulate, and solidify skin tissue in place in two minutes or less, and is a new breakthrough in bioprinting technology.

Deep epidermis, dermis, and subcutaneous tissue can be severely damaged. The currently preferred method of treatment is layer thickness skin grafting, where healthy donor skin is grafted onto the epidermis and part of the dermis. Performing a layered thickness graft on a large wound requires all three layers of tissue from a healthy donor's skin so that there are few qualified skin donors. Defective skin donors can make the wound area not completely covered, resulting in poor healing.

Although scientists have developed a large number of tissue engineered skin substitutes, they have not been widely used clinically. At present, most 3D bioprinters are bulky, slow, expensive, and most importantly not suitable for clinical applications. The research team believes that the in-situ skin printer they invented is a platform technology that can overcome these obstacles while improving the skin healing process.

Reported that this handheld skin printer resembles a white tape dispenser, "bio-ink" consists of protein-based biomaterials, including the most abundant collagen in the dermis, protein fibers involved in wound healing, etc. They can follow each "tape" extends. The device is only a shoe box size and weighs less than one kilogram. It also simplifies the use of traditional bioprinters and greatly reduces the amount of operational training required. Now, the research team plans to add some functions to the 3d printer, including expanding the area that can cover the wound. Except for 3D printer, the laser engraver is another gadget that many companies love to use. They hope to conduct more human clinical trials in order to eventually revolutionize burn treatment.

Laser technology is widely been used nowadays, do you know any?

At the end of 2017, China's well-known laser radar start-up company, SAIHE Technology, announced the launch of its solid-state rader, the Pandar GT, which will provide partners with test samples in the first quarter of the year 2019. In April 2017, SAIHE had already launched the Pandar 40, a scanning 40-line laser radar.

According to CEO Li Yifan, Pandar GT started research and development in 2015 and applied a brand-new technology named ZOLO (Zoomable Light Oscillator) to achieve the dynamic adjustment, viewing angle, angular resolution and imaging center area. This laser radar is designed and developed for vehicle gauge and mass production. We then interviewed Li Yifan. He disclosed some undisclosed news to us.

Li Yifan said that the Pandar GT is in the research and development stage, so it has not yet passed the rules of the car. The plan is to pass all vehicle regulations in 2019. Also in 2019, they plan to achieve large-scale production of the Pandar GT, when the price of the Pandar GT is expected to be suppressed to hundreds of dollars.

As for the specific details of the ZOLO technology, it is not disclosed because it involves technical confidentiality. We are not aware of the Pandar GT's resolution for the time being. Judging from the provided sample images, we can judge that the local resolution will be higher than that of the Pandar 40. Li Yifan told us some parameters of the Pandar GT: The maximum vertical field of view of the Pandar GT is 30 degrees, the maximum horizontal field of view is 40 degrees, and the maximum detection distance is 200m. The 200m probing is also the standard that the Pandar GT mass production product will reach.

At present, the prosperity of automatic driving has set off a global R&D and investment boom in laser radars, especially solid-state laser radars, and many players have poured in. In addition to professional equipment such as solid-state laser radar, the laser cutter, laser engraver is a more everyday and easier-to-operate gadget, which is more suitable for more amateurish players.

Do you know the Microsoft and ROOBO R&D Voice Development Board?

May 8, Microsoft Build 2018 opened. Microsoft’s CEO Nadella officially released the multi-MIC voice development board MSDDK jointly developed by Microsoft’s voice team and ROOBO, which is a software and hardware integrated solution for far-field speech recognition. This is the first developer hardware platform Microsoft has ever provided in the AI space.

It is reported that ROOBO has completed the design and implementation of MSDDK in audio, acoustics and hardware, and ROOBO has provided hardware directly to developers, and Microsoft has provided the Speech Service development platform. In conjunction with the cognitive services provided by Azure, it provides a wide range of languages and knowledge skills that can be widely used in smart home appliance, robot, smart audio speaker, android box and other scenarios.

At the Build conference, Microsoft also demonstrated a smart desktop device for multi-person conference equipment, which can simultaneously record the voice and images of multi-person conferences, mark different people's speeches and voice transcription, and separate archives to extract conferences. From the on-site demonstration, the application of this product solves several key technologies in the AI field, such as noise processing in a multi-user dialogue scenario, speaker speech separation in a multi-user dialogue scenario, and voice technology and image technology. This product is also cooperated by Microsoft and ROOBO to tap the technical potential of DDK development board.

For this cooperation, Dr. Xuedong Huang, Microsoft’s chief speech scientist and Microsoft Global Technology Fellow, said, “In the past few months with the joint project development of Microsoft, the ROOBO team has demonstrated strong cooperation spirit and technical strength. I hope ROOBO can play a greater role in artificial application and promotion of smart technologies and platforms with Microsoft. The advanced technology is rewriting the chapter of history."

Everybody is waiting for this 50-inch tablet - Microsoft Surface Hub 2

Maybe it is "mind-connected." Shortly after Luo Yonghao released TNT Workstation + Smartisan OS 6.0, a work-oriented office solution, Microsoft released Surface Hub 2, a large 50-inch tablet PC, in the United States. Microsoft did not disclose the price of Surface Hub 2. It is expected to be officially launched in 2019 (the price of the first generation Surface Hub was 9,000 US dollars).

The Surface Hub 2 uses a 50.5-inch 4K display with a 3:2 aspect ratio and 16:9 aspect ratio, which is 55-77 pounds less in weight than the previous generation and is also thinner than the first generation. Extremely narrow frame and support up to 4 Surface Hub 2 stitched together to create an 84-inch 4K oversized office "whiteboard".

Due to the reduced weight and size, the Surface Hub 2 can be placed on a rack that can be rolled and carried easily or mounted on a wall. Microsoft said that it is working with Steelcase to produce related supporting brackets. Surface Hub 2's specially designed hinges enable it to rotate from 0 to 90 degrees while dynamically adjusting the orientation of the content on the screen.

Based on Windows 10

Surface Hub 2 cheap android tablet is based on an enterprise software suite called "Microsoft 365," of course, it is just relatively cheap, which includes corporate office software such as Windows 10, Office 365, Enterprise Mobility Security, Microsoft Teams, and Microsoft Whiteboard. Of course, "cooperative work" is indispensable, allowing multiple people to use Surface Hub 2 at the same time.

Microsoft said that they are developing a scenario display model called "dynamic collaboration" so that people can use built-in fingerprinting to log in to Surface Hub 2, and pull their work into the cloud already stored in the cloud. In a single "collaboration" document, and place their ideas and documents in a workspace at the same time. After logging in, they can also access colleagues’ history and data.

According to Microsoft, Surface Hub is currently sold to more than 5,000 customers in 25 markets worldwide. More than half of Fortune 100 companies have purchased Surface Hub devices. Google also launched Jamboard, a 4K ultra-large display screen that costs up to $5,000. Cisco also introduced the Spark Board, which sells for $4,990. It also features Cisco's free Spark Flex corporate office suite.
