The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

OmniVision OV12890 sensor with 1,55 micron pixels 05.06.2016

OmniVision has introduced the OV12 12890-megapixel image sensor for high-end smartphone and phablet cameras.

The 1/2,3 inch sensor has 1,55 x pixels. 1,55 microns. The solution is made using proprietary PureCel Plus-S volumetric technology.

The OmniVision OV12890 sensor captures 12 MP (4096 x 3072 dots), 4K (3840 x 2160 dots), 1080p (1920 x 1080 dots) and 720p (1280 x 720 dots) resolutions. When working at maximum resolution, the shooting speed can reach 45 frames per second. When recording 4K material, this figure rises to 60 frames per second, and when using the 1080p format - up to 240 frames per second.

The sensor can be enclosed in a 10 x 10 x 6 mm module. In cameras based on it, a phase detection autofocus (PDAF) system can be used.

Trial deliveries of the OmniVision OV12890 sensor have already begun, and mass production is scheduled for the last quarter of this year.
