New car steering angle sensor

15.05.2007

In the automotive industry today, the development of electrical and electronic systems such as hybrid electric vehicles and electric power steering meet the challenges of fuel economy and driving comfort.

In this case, the electric power steering should be equipped with angle sensors to determine the angle of rotation and torque. In the past, magnetic sensors have been used for this purpose, such as sensors based on a hall element or a coordinate converter. However, most of these devices are installed inside and near electric motors or generators that require protection from magnetic noise.

Sumida's rotor angle sensor is designed by its German VOGT Electronic Components division using a non-ferromagnetic structure and has a high operating frequency. This unique development makes it possible to achieve immunity to magnetic interference noise of electric motors. The product does not need to be fixed on a rotary axis, and is suitable for a different number of pole pairs, therefore, it allows to achieve greater application flexibility.

Main applications: hybrid electric vehicle, electric power steering, ISO, X-by-wire (a safety system that allows you to keep the car working if individual elements fail), active suspension, passenger weight sensor.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Neutrino mass at rest measured 22.04.2024

Neutrinos, mysterious elementary particles, continue to be a fascination for particle physics researchers. They represent the key to understanding many fundamental aspects of nature. Recent measurements of the mass of neutrinos open new horizons in our understanding of their properties and role in the Universe.

A team of scientists from the Max Planck Institute for Nuclear Physics in Heidelberg, led by Klaus Blaum, carried out a landmark study aimed at measuring the resting mass of neutrinos. This measurement was key to determining the value of Q with high accuracy, which helps eliminate possible systematic errors in estimating the neutrino mass.

Neutrinos, as elementary particles, have a significant impact on physical processes, and their mass is becoming one of the central aspects in scientific research. Solar neutrinos, for example, are an integral part of cosmic radiation, and their interactions with matter can provide valuable information about the properties of these particles.

One of the important discoveries related to neutrinos is the phenomenon of "neutrino oscillations", which confirms that neutrinos have mass at rest, which contradicts the standard model of particle physics.

Neutrino mass studies are conducted using a variety of techniques, including tritium beta decay and electron capture from artificial isotopes. Experiments such as Katrin and ECHo aim for maximum precision in these measurements.

The Heidelberg pentatrap experiment used the Penning trap method, which allows one to determine the value of Q with high accuracy and eliminate systematic errors.

Measuring the mass of neutrinos is a complex and important task in modern physics. New research results, such as the one in Heidelberg, are helping us move closer to understanding the nature of these mysterious particles and their role in the universe.
