abstract:In a multielement antenna array (such as a Yagi-Uda antenna), the driven element or active element is the element in the antenna (typically a metal rod) which is electrically connected to the receiver or transmitter. In a transmitting antenna it is driven or excited by the RF current from the transmitter, and is the source of the radio waves.
The other, the "speculative element, " is driven by sentiment and emotion: hope and greed and thrill-seeking in bull markets, fear and regret and revulsion in bear markets.
Driven by Lumus' patented Light-guide Optical Element, a micro-display pod, and the Optical Engine which projects light into the lens -- where it is reflected back to the user's eye via reflectors embedded in the lens -- the Lumus' DK-32 delivers a bright 720p 3D-capable display that only weighs 27 grams.
