BPTO was considered the sixth most innovative IP institute in the world in 2021, according to an annual ranking released by the World Trademark Review (WTR), which analyzed 60 national or regional IP institutions.

The ranking was led by the IP institutes of the European Union and South Korea. The third position was Singapore, followed by the United Kingdom and Mexico. In sixth place, alongside the BPTO, were the IP institutions of Australia and Chile.

In relation to Brazil, the publication highlighted that the BPTO had significant growth in the ranking in recent years, leaving 41st place in 2018 and rising about 20 positions in 2021. WTR highlighted the Institute’s actions to reduce the backlog, modernize its systems electronics, as well as stimulate innovation and economic development through IP assets.

Use of fingerprints on smartphone screens has been used for a long time. The technology serves well and has stagnated in recent years. However, Xiaomi intends to change that and has now filed a patent application for a fingerprint sensor that can be used across the entire screen of the device.

Xiaomi patents fingerprint recognition technology anywhere on the screen

According to the latest data from the Chinese Patent Office, the company has obtained a patent for fingerprint scanning technology. The technology allows you to use the scanner more freely without having to place your finger on a certain point on the screen.

In the patent, Xiaomi described the operation of a network of integrated infrared LED elements located between an AMOLED display and a capacitive touch layer. The network of “receivers” will be under the display. These elements will form the basic building blocks of the new scanner, which will serve the entire screen of the device.

Xiaomi’s patented fingerprint sensor

When the user touches the screen with their finger, the touch layer records the touch, its location, and the shape of the fingerprint, after which the LED elements begin to emit infrared light in the desired area. In this case, elements elsewhere on the screen will remain inactive.

Infrared light is then reflected off the fingertip and projected onto the receivers. The system will process the data to obtain a “card” of the fingerprint and the smartphone will compare it with the sample saved in memory. Once the fingerprint is identified, the user can unlock the device by touching any part of the screen.

Xiaomi’s patent is a major advance in fingerprint recognition and a smartphone, which currently has small screen spaces for this recognition. In addition, users increasingly seek convenience, and this patent brings that too.

In August, Huawei patented its technology for a similar purpose in several markets, including China, Europe, USA, Japan, Korea, and India, but the development did not find commercial use, which, according to the site, must have been due to US sanctions that seriously restrict the company’s technological capacity. As Xiaomi has not yet faced such sanctions, new scanners may be launched shortly.

The Walt Disney Company obtained a patent for a device capable of producing virtual reality and augmented reality without the need for glasses, headsets, or digital devices. Virtual World Simulator had its name registered with the US Patent and Trademark Office on December 28 and should bring something unprecedented until then.

The patent suggests that Disney intends to raise the level of digital simulation to something unprecedented, far beyond virtual reality and augmented reality, two of the main production focuses of large technology companies. The Disney theme parks metaverse must connect digital, data, and physical elements in a “virtually enhanced physical reality and physically persistent virtual space,” according to the documentation.

Disney would be willing to create a virtual universe inspired by Disneyland that would allow the simulation of animated characters and theme park attractions in a virtualized, 3D, and realistic way. The technology would use three-dimensional images generated by multiple projectors capable of generating a high rate of images per second.

How does Virtual World Simulator work?

The premise of Virtual World Simulator would be the use of the SLAM (Simultaneous Localization and Mapping) technique, which tracks in real-time the user’s point of view and implements changes in the images, which gives a sensation similar to being in motion.

The 3D virtual effects would be projected onto real park locations and could bring animated characters to life or simulate animated objects, props, and artwork. If all goes well, the experience of visiting Disneyland and Walt Disney World parks could deliver an even more enchanting and unique experience.

According to Founders Legal’s technical and patent technology consultant, John DeStefano, the entertainment giant would come out ahead of competitors by bringing simulations independent of the phone screen or headphones. “Disney has developed a system that is almost similar to a movie projector to project onto a real surface what humans see on a screen,” he explained in an interview with SiliconValley.

There’s still no time frame for Disney to deploy the Virtual World Simulator technology, but it likely won’t take that long, as the patent is often one of the last processes performed in the development of a product.

A study by researchers at the Augusta University School of Medicine, Georgia, USA, found that cannabidiol (CBD), one of the active ingredients in marijuana, was able to reduce, in mice, the size of a highly aggressive brain tumor and lethal. After inhaling the compound, the animals began to produce fewer substances that favor the growth of glioblastoma.

To simulate brain cancer in mice, the researchers used modified human glioblastoma cells (adapted for animals), creating what is called “orthotopic glioblastoma”, the most realistic possible model for the tumor, produced artificially outside the human body.

After eight days, the disease was already active and aggressively in the animals’ brains. On the ninth day, the team of researchers started the treatment with daily doses of inhaled cannabidiol, while some animals received a placebo, to control the work. The experiment lasted seven days and the study was published in the specialized journal Cannabis and Cannabinoid Research.

Scientists observed a significant decrease in tumor size in imaging tests done in mice that inhaled cannabidiol, not seen in animals that ingested a placebo.

Currently, the treatment of glioblastoma-type brain cancer is surgery followed by chemotherapy and radiation therapy. However, the results are usually not satisfactory, as this type of tumor is resistant to drugs.

The scientists’ idea is to use cannabidiol — if its beneficial effects are proven in further studies — in conjunction with the treatment already used in people diagnosed with glioblastoma.
