In February 2020, an American architecture student named Caleb Brackney decided to buy a 1995 school bus for $3,000. The vehicle was later converted into a mobile home by Brackney at a cost of $7,000 to upgrade. Caleb Brackney spent the next six months designing and completing his new home by himself, including refurbishing the exterior, removing the old seats, reinforcing the floor and ceiling, and installing convenience equipment. benefits inside the car. Caleb Brackney started moving into his mobile home in August 2020. This mobile home is named The Roamer, after the town where the old bus was purchased. Most of the interior space of the bus is used as a living place with all the necessary facilities of a small house, the total area used is about 20 square meters. Right behind the driver’s seat is a cooking area with an oven, microwave, sink… The space between the car is used as a place to study and work with a wooden table next to the window. This is also where Brackney can play the piano and entertain. Taking up the most space is a resting place with a double bed, next to it is a sofa and TV. Supplying domestic electricity for mobile homes is a generator system, solar batteries and electricity storage batteries. The house’s clean water tank has a capacity of 190 liters, enough for Brackney to live for about 2 weeks. Most of the items and materials that make up The Roamer bus are recycled to protect the environment. Brackney plans to live in his mobile home for the next 2-3 years until he completes his master’s degree. Turn an old bus into a barber shop in Ho Chi Minh City with VND 400 million With the desire to move to many places so that he could cut everyone’s hair, Mr. Nguyen Hoai Thanh converted the bus into a mobile barber shop at a cost of nearly 400 million VND.

Recently, the team upgraded the technique to power and program the multipoint biostimulator from a single transmitter. Thanks to new research, electrical and computer engineer Kaiyuan Yang and colleagues at the George R. Brown School of Engineering (Rice University) won an award at the Society of Electrical and Electrical Engineers’ Custom Integrated Circuits Conference death (IEEE). The researchers performed experiments showing that an alternating magnetic field can be controlled by a battery-powered generator outside the body. The transmitter can be mounted on a belt or harness, powering and programming two or more implants at least 60 millimeters away. The implant can be programmed with a delay measured in microseconds. That could allow them to coordinate the activation of multiple wireless pacemakers in individual heart chambers, says engineer Yang. “Our study shows that it is possible to program the implants to stimulate in a coordinated pattern. We sync every device, like a symphony. That gives us a lot of scope in stimulant treatments, whether it’s for the heart rhythm or the spinal cord.” The scientists also experimented using small implants. Each tissue is about the size and weight of a vitamin. Experiments performed on hydra vulgaris rodents have demonstrated that, for at least a short distance, such devices can stimulate two separate hydras to contract. Then, activate a fluorescent tag to respond to electrical signals and respond at controlled amplitudes along the rodent’s sciatic nerve. “A study on spinal cord regeneration showed that multipoint stimulation in a certain pattern helps restore the nervous system. Several clinical studies are underway, but all are using desktop devices. There is no implantable tool that can do this,” said engineer Yang. Lab devices, called MagNI (for electromagnetic nerve implantation). MagNI was introduced early last year as a cordless spinal cord stimulator for power and programming. That means the wire does not need to be passed through the patient’s skin. Because, putting the wire through the skin is a method that can cause infection.

“We are the first manufacturer in the world to combine the internal combustion engine and the electric motor in a small UAV. In flight, internal combustion engines are not the main engine, they only provide energy. for generators, battery buffers and electric motors with electronic systems working, “said project leader Khamitov. Aero Company’s product. The electric motor increases uptime, making the aircraft quieter enough to perform unexpected secret missions. Meanwhile, similar products using other internal combustion engines can hardly do that. It is known that, before announcing the ZALA 421-16E5G, ZALA Aero Company also made a surprise with ZALA 421-16E5. This UAV is not only capable of operating 16 hours continuously in the air but is also designed to return to base in the event of a loss of contact with the control center. In the UAV’s electronics department there are cameras with high resolution cameras, night vision equipment and thermal imaging equipment. The images are stacked to facilitate terrain monitoring at any time of day. “The design of this UAV model uses unique technology to create a quality and reliable product. The engine management system is completely inside and controls every detail of the aircraft. In addition, the ZALA 421-16E5 can also be deployed from an electrically controlled launch system in special terrain areas. This is a feature that is being developed with attention in new UAV models today. Old drones can only take off at flat runways and are carefully prepared, “said Zala Aero design director Alexander Zakharov. In addition, Mr. Zakharov also ensured that the ZALA 421-16E5 protective and landing gear has a special design to make the process safe. What makes this UAV so special is its ability to return to the base in case something goes wrong with the control system. Zala Aero is a subsidiary of the Kalashnikov group mainly develops and manufactures air reconnaissance and reconnaissance weapons. The company’s main products include UAVs, helicopters and hot air balloons.
