This is the first-ever iPad with which Apple has introduced trackpad support
Posted by Quinn Sena in categories: computing, electronics
Apple’s latest iPad — the iPad Pro — is its most-powerful and comes with several first-time features. This is the first iPad with a a dual-camera, a trackpad, a Magic keyboard and LiDAR scanner. It is the most-powerful iPad Apple has made and is set to give tough competition to a lot of Windows-powered laptops. Here are 15 things you should know about the new iPad Pro:
This could used to emp laser missiles or other targets.
The electromagnetic pulses (EMPs) generated during the interaction of a focused 1.315-μm sub-nanosecond laser pulse with a solid hydrogen ribbon were measured. The strength and temporal characteristics of EMPs were found to be dependent on the target density. If a low density target is ionized during the interaction with the laser, and the plasma does not physically touch the target holder, the EMP is weaker in strength and shorter in time duration. It is shown that during the H2 target experiment, the EMP does not strongly affect the response of fast electronic devices. The measurements of the EMP were carried out by Rohde&Schwarz B-Probes, particularly sensitive in the frequency range from 30 MHz and 1 GHz. Numerical simulations of resonant frequencies of the target chamber used in the experiment at the Prague Asterix Laser System kJ-class laser facility elucidate the peaked structure of EMP frequency spectra in the GHz domain.

Graphene forms under microscope’s eye
Posted by Omuterema Akhahenda in categories: electronics, materials
You don’t need a big laser to make laser-induced graphene (LIG). Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns.
Scientists record the formation of foamy laser-induced graphene made with a small laser mounted to a scanning electron microscope. The reduced size of the conductive material may make it more useful for flexible electronics.

Excalibur S GPS/laser-guided artillery shell homes in on moving target

Raytheon and the US Navy have successfully fired a precision-guided munition that can be fired from a howitzer and zero in on a moving object. The recent test of the Excalibur S round not only demonstrated its ability to switch from GPS to laser guidance to find its target, but also that its electronics and sensors can withstand the shock of being fired out of a gun.
The Excalibur S is the latest variant of Raytheon’s Excalibur line of smart projectiles. Developed by Raytheon and BAE Systems Bofors, it uses the GPS technology from the Excalibur Ib, and combines it with a semi-active laser seeker that allows it to home in on moving land and maritime targets with a miss radius of under two meters (6.5 ft).

Maxar says last year’s unnamed GEO order is new Intelsat satellite
Posted by Genevieve Klien in categories: electronics, satellites
WASHINGTON — Maxar Technologies says the geostationary satellite order it disclosed in November without naming the customer is a high-throughput Intelsat spacecraft that will also carry a pollution sensor for NASA.
Intelsat announced Feb. 3 that it had selected Maxar to build Intelsat-40e, a satellite that will provide high-throughput coverage of North America and Central America.
Intelsat-40e will also carry NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) hosted payload under a NASA contract with Maxar.

Rare ‘floating city’ deep-sea creature caught on camera by stunned scientists
Posted by Genevieve Klien in categories: electronics, governance
A creature so rare that it has only a few recorded sightings across the world has been caught on camera by stunned scientists.
The benthic siphonophore, which looks like a single animal, is actually a “floating city” of many smaller organisms working together.
The creatures are so rarely seen that their ecology is almost unknown, though they are thought to make their home at depths of up to 3000m.
