Virtual reality headsets have gained tremendous popularity. However, one common problem tends to occur— the headsets can make users feel sick. Nausea can be experienced because users’ eyes are being tricked into seeing a 3D scene, when, in fact, they are staring at a 2D fixed-distance display. One possible solution …

Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which …

For decades U.S. warfighters have benefitted from advanced night-vision technology, allowing pilots to fly low-level missions on pitch-black nights and ground forces to conduct operations against adversaries in the dark. Traditional Night Vision Goggle (NVG) systems provide the wearer with enhanced visibility in low-light conditions by exploiting the natural near-infrared …

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Some examples of remote sensing are special cameras on satellites and airplanes taking …
