ELTA of France is looking for international distributors for its latest range of Argos data transmitters – the HAL-2 and the VHAL-2. These new high-performance products have been designed to operate in the most hostile environments. Argos – with more than 11,000 active platforms throughout the whole world – has become the preferred system for observing and monitoring the environment on a worldwide scale.
The new-generation Argos HAL-2 (High Accuracy Locator) transmitter has an excellent and reliable frequency stability, making it possible to pinpoint objects to an accuracy of between 300 metres and 400 metres. The VHAL-2 (Very High Accuracy Locator) transmitter is fitted with an integrated GPS device. It enables even more accurate pinpointing, to within a few metres, while at the same time retaining the same general characteristics and overall performance as the HAL-2.
The HAL-2 and VHAL-2 have an exceptional frequency stability. Owing to their very low electric-power consumption (less than 50µA), highly elaborate miniaturisation and sturdiness, this new range can be adapted to all environmental applications, even the most demanding and critical.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
