Samsung TV remote control charges itself by harvesting Wi-Fi signals

INTRO: Samsung has created a television remote control that doesn’t require batteries, as it draws power by harvesting otherwise wasted energy emitted by Wi-Fi routers.
The firm originally launched the Eco Remote as a solar-powered device last year. Samsung said at the time the remote could prevent 99 million AAA batteries going to landfill over the next seven years. Now, at the 2022 CES technology trade show in Las Vegas, the firm has revealed a new version of the device that includes a tiny antennae that can capture Wi-Fi signals from a distance of up to 40 metres, allowing it to charge even in dark rooms.
The company says it will include the remote control with new televisions and other home appliances. Samsung didn’t respond to a request for comment on the exact technical specifications of the device... (MORE - details)
Researchers at UCLA develop computer-free technology for deciphering holograms

INTRO: UCLA researchers developed a computer-free system that can instantaneously reconstruct holograms, helping further technology in the field of optical processing, according to an Oct. 27 study.
Holograms are a form of data storage that house the information required to recreate 3D objects on a digital screen, which are commonly used to visualize microscopic objects such as algae and bacteria, air pollution particles and viruses.
The Ozcan Research Group has been researching new methods of retrieving the information stored in holograms that does not require the processing power of a computer, said Aydogan Ozcan, the senior author of the study and a distinguished professor of electrical and computer engineering.
The researchers’ approach to deciphering holograms involves replacing computers with a physical network of five 3D-printed layers of screens, said Sadman Sakib Rahman, the lead author of the study and a graduate student in electrical and computer engineering. The screens allow light to pass through, bending the light particles to specific locations on the final layer, he added. The location of light particles on the final layer corresponds to the type and physical shape of the object, allowing the network to recognize and reproduce the scene in the hologram...
