Infrared and 3D Sensing: How Machines Are Learning Human Senses
Rudimentary infrared products and applications, recognizable by their characteristic red lights that respond to gestures, are a familiar sight to many. Touchless household garbage cans that open on their own in response to hand gestures and autonomous robotic household vacuum cleaners that dodge walls and other barriers, or even recharge on their own, are examples […]

Next-Gen Encryption to Confront Next-Gen Threats
The digital underworld is employing increasingly sophisticated technologies to penetrate enterprise infrastructure, but in the continual game of one-upmanship new encryption technologies to thwart these efforts are emerging from the lab at a steady clip. In this never-ending battle, however, we can expect to see occasional victories on both sides, so the question for data […]

Chromatic Aberration
What Does Chromatic Aberration Mean? Chromatic aberration is an optical phenomenon in which correct images cannot be produced due to the inability of the camera lens to focus the wide range of wavelengths of light on the same plane. In other words, the colors are wrongly refracted/bent by the camera lens, causing a mismatch at […]

Duplexer
What Does Duplexer Mean? A duplexer is an essential component in modern gadgets using radio communications. It permits duplex communications, which allows bidirectional transmission on a single path. There are many different types of duplexers. An example of a duplexer based on frequency is a wavelength filter, while a duplex based on polarization is an […]

Doppler Effect
What Does Doppler Effect Mean? The Doppler effect is a phenomenon related to the effects of moving objects on an electromagnetic field. In this, an observer in relative motion to a wave experiences a change in the frequency or wavelength of the wave. For example, consider a person standing near a road. A honking vehicle […]

Digital Audio Tape
What Does Digital Audio Tape Mean? Digital Audio Tape (DAT) is a recordable digital audio format. It was introduced in 1987 by Sony and looks similar to compact cassettes, but is smaller in size. Used primarily for playing and recording audio and intended as a replacement for analog audio compact cassettes, Digital Audio Tape was […]

Computer-To-Plate
What Does Computer-To-Plate Mean? Computer-to-plate (CTP) is an imaging technology which helps to transfer a digital image generated in a computer directly to a printing plate. Before CTP, the technology used was computer-to-film (CTF), where the image output was passed to a photographic film, and the output film was then used to make the printing […]

Extremely Low Frequency
What Does Extremely Low Frequency Mean? Extremely low frequency (ELF) is the designation given by the International Telecommunication Union (ITU) for radio waves or electromagnetic radiation with frequencies that range from just 3 Hz to 30 Hz and with corresponding wavelengths. But in atmospheric science, ELF is alternatively given a range of 3 Hz to […]

Ground-Plane Antenna
What Does Ground-Plane Antenna Mean? A ground-plane antenna is a form of dipole antenna designed to work with an unbalanced feed line. A ground-plane antenna is more of less one half of the dipole and mounted above the ground plane. Ease of fabrication and cost makes the ground-plane antenna one of the popular antennas in […]
