Appl. No.:

10/113114

Jonathan Barsade - New Haven CT, US
Steven Y. Cho - Sherman Oaks CA, US

International Classification:

G06F 21/00

US Classification:

705 1473, 705 1459, 715803, 715808

Abstract:

A network advertising system and method includes a network server, a computer user, an electronic banner advertisement (BA) file, multiple web page files, a BA program, and a monitor. The BA is displayed on the monitor in a window of a browser program from about the point in time that a new web page is requested to about the point in time that the web page file corresponding to the new web page is downloaded onto the user computer and ready for viewing. The BA offers an advertising venue that will serve up a very discernible advertisement, uncluttered by other content that captivates the viewer's interest, at a point of time that a web (Internet or other network) surfer is willing and amenable to review additional data and information. This is typically a down-time, interstitial period, during a browser session. However, by displaying the advertisement as described, most web surfers will pay attention to the BA and the message that it is providing.

International Classification:

US Classification:

Abstract:

The present invention provides a software-based electro-optic modulator bias control system resident in an optical transceiver including an electro-optic modulator that includes an optical-to-electrical converter including a transimpedance amplifier, an analog-to-digital converter, and a software algorithm, wherein the software algorithm is operable for determining an optimum bias voltage applied to the electro-optic modulator by discovering a maximum average optical power transmitted by the electro-optic modulator, or quadrature point, wherein the quadrature point is discovered by determining at what bias voltage the slope of an average optical power transmitted by the electro-optic modulator, defined as an optical power change given an incremental bias voltage change, is equal to zero. The software-based electro-optic modulator bias control system also includes a control loop operable for determining if a radio frequency port of the electro-optic modulator is driven to a peak-to-peak voltage that is greater than (over-driven) or less than (under-driven) the peak-to-trough voltage of a response curve of the electro-optic modulator.
