Mobile phone embedded in teeth

19.08.2002

British engineers D. Auger and D. Loizo proposed the idea of creating mobile phones built into the teeth of their owners.

The miniature size of microcircuits that process radio signals makes it possible to implement this idea in the near future. The "dental telephone" will be implanted directly into the teeth during a routine visit to the dentist. The messages received by such a phone, after being converted into acoustic signals through the bones of the head, will enter the inner ear.

Information transmitted in this way is heard only by one person - the one to whom it is addressed. Therefore, it will be possible to use the "dental telephone" at any time and in any place, even in cinemas and museums.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Chip for cheap car surround view cameras 08.04.2014

Freescale Semiconductor and Broadcom have jointly developed a microprocessor for electronic systems that make driving easier. We are talking about parking assistants, rear-view and all-round cameras, tracking systems for "dead" zones.

The novelty called Qorivva MPC5606E is a microcontroller (MCU) with a physical layer transceiver (PHY) for BroadR-Reach networks (automotive Ethernet). The latter are promoted by the Open Alliance SIG, which, in addition to Broadcom and Freescale, includes such large companies as NXP, BMW, General Motors, Renault and Daimler.

Using BroadR-Reach technology, the announced chip receives compressed video data from multiple cameras installed on the vehicle and sends the picture to the screen of the infotainment system. The video stream coming from the camera to the data network is compressed using the Motion JPEG algorithm.

According to the developers, thanks to the new solution, automakers will be able to reduce the costs associated with connecting the network in the car by 80%, as well as reduce the total weight of the cables involved by 30%. This, in turn, will allow the use of all-round cameras in low-cost cars.

Freescale says the tiny 8mm x 8mm chip is designed to reduce the size of automotive camera modules by up to 50%, and therefore reduce their cost and production time. Such cameras are easier to hide behind the grille, side mirrors or bumper.

The Qorivva MPC5606E is equipped with 96 kilobytes of SRAM and 512 kilobytes of flash memory. The core in the processor was created using Power Architecture technology and operates at a clock frequency of 64 MHz.

The first samples of Qorivva MPC5606E have already been sent to automakers for testing. Serial production of the microchip will begin at the end of 2014. It is expected that next year affordable cars with all-round cameras and other electronic assistants will appear on the roads of the world.
