Wavecom Wireless Processor

27.10.2009

The Wavecom wireless processor from Sierra Wireless works with the CAN bus. The C-CAN solution allows the Q26xx or WMP100 wireless processor to work with the CAN bus. The "C-CAN Application Note" application example uses an external inexpensive CAN 78k0 controller (NEC) and communicates via the SPI interface.

To access the CAN transceiver, a free library with a set of simple APIs is offered. Data transmission can be carried out both at low (Low Speed CAN - up to 125 kbps) and high (High Speed CAN up to 1 Mbps) speeds. CAN 2.0A and CAN2.0B interface supported (11 or 29 bit message ID); it is possible to receive up to 15 "message ID" (up to 4 masks); an interrupt signal is provided to wake up from a low bus power state.

For rapid CAN-bus prototyping, the "C-CAN 78k0 Development Kit" is available, which includes an additional CAN transceiver board for Q2786 DK/Q2687 DK/WMP100 DK debug kits.

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 ... >>

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, ... >>

Ford smart suspension with pothole protection 01.07.2018

Bad roads are one of the main causes of accidents worldwide. In addition, potholes often lead to serious damage to the chassis and wheels of vehicles. Ford sees a partial solution to the problem in the introduction of "smart" suspension, which recognizes bumps on the road and reduces the negative consequences of hitting them.

The pothole protection system is based on an active suspension with continuously variable damping force (Continuously Controlled Damping). The electronic unit, coupled with a special software module, continuously analyzes data from 12 sensors. Sensors are polled every 2 milliseconds, which allows you to instantly respond to changing traffic conditions.

The system recognizes the moment when the wheel begins to fall into the pit, and the adaptive suspension instantly adjusts the stiffness of the shock absorbers in such a way that the wheel, when it hits the pothole, practically does not touch the bottom of the depression and, thus, “jumps over” it. In other words, the wheel remains in a “compressed” state, due to which, when exiting a pothole, it does not beat so much against its edge, which makes the passage of bumps more comfortable for passengers and reduces the load on the suspension.

When driving through a pit with the front wheels, the rear wheels are prepared for unevenness in advance, which additionally protects them from impact.

The system is already available on select Ford models, including the Mondeo business sedans, Galaxy minivans and S-MAX minivans in Europe. In addition, the company is starting to offer this solution for the C segment for the first time: active suspension with pothole protection is available for the new version of the Focus.
