Patent number: 9118559Abstract: Methods and apparatuses described herein are configured to calculate the instantaneous bit rate of a network connection. According to certain aspects, conventional solutions measure average bit rate of a network, whereas the techniques described herein are configured to measure the instantaneous bit rate. According to further aspects, structurally, conventional solutions require external devices (hosts or servers) and a plurality of data packets for measurement, whereas the present invention is self-referenced and requires, in principle, only two network packets, of any type, for measuring the instantaneous bit rate. The instantaneous bit rate can then be used to adjust the transmission bit rate of network packets to optimize the network connection such that the bandwidth of the network connection is fully utilized and packet loss is avoided.Type: GrantFiled: April 6, 2012Date of Patent: August 25, 2015Assignee: SEJENT CORPORATIONInventors: Edward J. DeWath, Loc T. Le

Patent number: 6522794Abstract: A flat panel display is based on a new switching technology for routing laser light among a set of optical waveguides and coupling that light toward the viewer. The switching technology is based on poled electro-optical structures. The display technology is versatile enough to cover application areas spanning the range from miniature high resolution computer displays to large screen displays for high definition television formats. The invention combines the high brightness and power efficiency inherent in visible semiconductor diode laser sources with a new waveguide electro-optical switching technology to form a dense two-dimensional addressable array of high brightness light emissive pixels.Type: GrantFiled: January 31, 2000Date of Patent: February 18, 2003Assignee: Gemfire CorporationInventors: William K. Bischel, Michael J. Brinkman, David A. G. Deacon, Edward J. DeWath, Mark J. Dyer, Simon J. Field

Patent number: 5911018Abstract: An extremely low-loss optical switch element includes a first waveguide segment having first and second regions longitudinally-adjacent with each other and having an index of refraction difference which is greater when the switch element is in an "on" state than when it is in an "off" state. The two regions have a common boundary which is oriented at an angle in the first waveguide so as to redirect optical energy through total internal reflection when the switch element is in the "on" state. The switch element further includes a second waveguide segment spaced from the first waveguide segment and disposed and oriented to guide optical energy redirected from the first waveguide segment when the switch element is in the "on" state.Type: GrantFiled: November 18, 1997Date of Patent: June 8, 1999Assignee: Gemfire CorporationInventors: William K.
