Camera-based application that identifies and interprets user motions.
Industry:Technology
Gesture control is the ability to recognize and interpret movements of the human body in order to interact with and control a computer system without direct physical contact. The term “natural user interface” is becoming commonly used to describe these interface systems, reflecting the general lack of any intermediate devices between the user and the system.
Industry:Technology
Geothermal power is a highly geographically variable renewable energy source. Traditionally, energy is produced from geothermal resources that have a combination of three attributes: high temperature rock, saturation of the rock mass and high permeability to allow water (the heat transfer agent) to move throughout the target geothermal field. Since geothermal power output can be maintained at a steady rate, it can be used as a renewable source of base load, unlike wind and solar.
Industry:Technology
Geothermal cooling is different from using geothermal energy to generate power. It uses the near-constant temperature of the earth just below the surface to provide cooling capability. Geothermal cooling is not new; throughout history, people have kept foods and beverages, such as wine, cool by storing them below ground in cellars. For data centers, geothermal cooling is implemented using a closed-loop piping system filled with water and/or a coolant that runs through vertical wells under the ground, filled with a heat-transferring fill.
Industry:Technology
Orbital plane that is geosynchronous with the earth’s equatorial plane (that is, zero inclination), also known as the Clarke Belt, named after Arthur C. Clarke. It is also an object orbiting the earth at the earth’s rotational speed and with the same direction of rotation.
Industry:Technology
Satellite that appears to be located at a fixed point in space when viewed from the earth’s surface. Satellites located in geosynchronous orbit move in time with the rotation of the earth. Geostationary satellites are located 22,237 miles above the earth’s surface. Most VSATs and DBS satellites are placed in geosynchronous orbits (GEOs). See also DBS and VSAT.
Industry:Technology
Geospatial mashups are applications that can display many sources of information and the geographical relationships among them. A mashup is a lightweight, Web-based, composite application, with no native data store or content repository. What makes a mashup geospatial is the ability to view multiple data repositories or even real-time data streams within a consistent geospatial context. Vendors may embed business intelligence (BI) functionality and in-memory online analytical processing (OLAP) in more comprehensive product offerings.
Industry:Technology
A geographic information system (GIS) is a collection of computer hardware, software and geographic data for capturing, managing, analyzing and displaying every form of geographically referenced information, often called spatial data.
Industry:Technology
Creating a virtual boundary in which a device, individual or asset can be tracked and monitored or detected if the boundary is violated. Examples are the tracking of pets, children and Alzheimer’s patients, criminals sentenced to home detention, trucks and high-value cargos.
Industry:Technology
Previously known as unlicensed mobile access (UMA), a GAN (generic access network) is a network architecture designed to support seamless connectivity between wide-area cellular networks, such as GSM/GPRS, and LAN technologies, such as Wi-Fi or Bluetooth — it is an example of fixed-mobile convergence.
