Description
Diffractive optical elements, DOEs, were designed for applications with lasers and high-power lasers. Used as multi-spot beam splitters, in beam shaping, and beam profile modification, such elements offer endless possibilities in different application fields.
Diffractive optical element uses a thin micro structure pattern to alter the phase of the light propagated through it. When a laser beam is transmitted through a diffractive optical element (DOE), it can be transformed into an almost arbitrary light pattern in the observation plane.
Description
High-frequency inductors consist of ceramic materials made of glass and internal/external electrodes made of silver. These inductors can be applied usefully for high frequency of 100 MHz or higher because they have high Q characteristics in high frequency, the SRF characteristics in a high-frequency band, and low resistivity. They are mainly used for impedance matching circuits in RF systems.
Description
A hearable device is a kind of microcomputer that is positioned in the ear and is fitted in the ear canal of the user. This kind of device makes the use of wireless technology to enhance and complement the hearing experience of the wearer. There are many exciting and limitless possibilities of the hearable devices that are experiencing an excellent reception in the market. An area of application which has enormous applications in the field of hearable devices is the area of augmented hearing.
The word “hearables” is coined at the beginning of 2014, referring anything that fits in or on an ear that contains a wireless link or Bluetooth, whether that’s for audio, or remote control of audio augmentation (qv).
Description
An HDTV antenna is a piece of electronic equipment designed to receive television broadcasts in the form of electromagnetic signals that are being transmitted "over the air". When a television station broadcasts its programming, it is converted from audio and video information into these electromagnetic signals.
Description
Hard drives store information magnetically on a spinning platter about 30% smaller than a CD. They also keep small amounts of data stored within RAM (Random Access Memory) chips found elsewhere in the casing. The only method of completely eliminating that information is to blast the hard drive with a magnetic field. The machines that do this are called Degaussers.
Hard Drive Degaussers are used to de-magnetize a hard drive and therefore erase the data on it. Degaussing is an NSA approved method of data erasure for hard drives. It is recommended that after using a degausser, a drive destroyer device is used to complete the secure data destruction.
Degausser is a machine used to eliminate data stored on computer and laptop hard drives, floppy disks and magnetic tape, by randomly changing the alignment of magnetic domains on the medium.
Degaussing takes its meaning from Johann Gauss (1777-1855) a mathematician who studied and worked on electro-magnetic fields. Data is stored on magnetic media by making very small areas called magnetic domains change their magnetic alignment to be in the direction of an applied magnetic field. Degaussing magnetic media leaves the domains in random patterns with no preference to orientation, thereby rendering previous data unrecoverable. A degausser is therefore used to completely erase all audio, video and data signals from magnetic storage media.
Description
Geotechnical sensors can provide information about the physical properties of the subsurface environment, for example, density, competence, and thickness of layers of soil or sediment. Sensors can provide information about stratigraphy, estimate depth to groundwater, or approximate hydraulic conductivity. An investigator must understand the properties and structure of soils and sediments to characterize a site accurately, as these conditions will affect sampling strategies and selection of technologies. Knowledge of the subsurface will also be critical when determining the location, extent, fate and transport, and attenuation of subsurface contaminants.

Increased use of flexible OLED displays in smartwatches and rising demand for OLED displays for use in smart wearable devices to drive the growth of the wearable display market.
Description
Gallium Arsenide (GaAs) is a compound semiconductor: a mixture of two elements, Gallium (Ga) and Arsenic (As). Gallium is a byproduct of the melting of other metals, notably aluminum and zinc, and is rarer than gold. Arsenic is not rare, but it is poisonous.
Description
Flex LED Strip Lights are thin flexible printed circuit boards with LEDs and resistors attached that populated by surface mounted light-emitting diodes (SMD LEDs) that usually comes with an adhesive backing. These Flex LED Strip Lights come in many configurations meaning one can be very bright to light an entire room and another less bright for accent lighting. LED flexible strips can also be made to use any usable wavelength or color that is desired for your home or business project.
