DARPA’s new 1.8-gigapixel camera is a super high-resolution eye in the sky

“DARPA recently revealed information on its ARGUS-IS (Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System), a surveillance camera that uses hundreds of smartphone image sensors to record a 1.8 gigapixel image. Designed for use in an unmanned drone (probably an MQ-1 Predator), from an altitude of 20,000 ft (6,100 m) ARGUS can keep a real-time video eye on an area 4.5 miles (7.2 km) across down to a resolution of about six inches (15 cm).”

Army tests vehicle-mounted laser against multiple targets

The Army used a vehicle-mounted high-energy laser for the first time to successfully engage more than 90 mortar rounds and several unmanned aerial vehicles in flight. 

This was the first full-up demonstration of the HEL MD in the configuration that included the laser and beam director mounted in the vehicle, according to officials of the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command. They said a surrogate radar, the Enhanced Multi Mode Radar, supported the engagement by queuing the laser.

The demonstration and testing confirms the capability of a mobile solid-state laser weapon system to counter mortars, UAVs, and intelligence, surveillance and reconnaissance sensors mounted on the UAVs, officials said.

The recent testing utilized a 10-kilowatt class laser.”

Implantable Device Manipulates and Records Brain Activity

“For the first time, researchers have implanted an electrode that can record neural activity while it simultaneously delivers electric current to the brain.

Minneapolis-based medical device company Medtronic developed the device, which can also adjust its electrical output in response to the changing conditions of the brain. This automated control could one day improve deep brain stimulation treatment and even enable doctors to use the device to treat more conditions, experts say.

..The patient trials that launched on Wednesday will test whether Medtronic’s new device can safely record electrical activity in a patient’s brains while also delivering electric currents. These tests will explore how patients’ brains respond to deep brain stimulation therapy. However, according to lab animal tests, the device is capable of not only sensing the electrical activity of the brain tissue it sits in but of also changing its output accordingly.”
