Publication number: 20120287229Abstract: A method for generating a video output signal that may receive a plurality of input video signals from a number of participants. The input video signals may have a plurality of input frames. The video output signal may comprise a plurality of output frames. A first of the output frames generally has at least a first slice having (a) a first coded portion carrying the image from a first of the participants and (b) a first unencoded portion for the image from a second of the participants. A second of the output frames generally has at least a second slice having (a) a second coded portion carrying the image from the second participant and (b) a second unencoded portion for the image from the first participant. The frames of the video output signal are generated as soon as one of the frames of the video input signal are received.Type: ApplicationFiled: April 18, 2012Publication date: November 15, 2012Inventors: Chih-Lung Yang, Lars Chapsky

Patent number: 8207323Abstract: A nanoscale motion detector attaches a gold nanorod (30) to the rotating arm (26) of a molecular structure (10) to cause the nanoparticle to rotate. The molecular structure is an F1-ATPase enzyme. The gold nanorod is exposed to a light source. The long axis of the gold nanorod scatters red light when the nanorod is in a first position. The short axis of the gold nanorod scatters green light when the nanorod is in a second position. A polarizing filter filters the red and green light to detect the rotational motion by observing alternating red and green lights. A detection DNA stand (50) is coupled between the gold nanorod and the molecular structure. The detection DNA strand hybridizes with a target DNA strand (58) if the target DNA strand matches the detection DNA strand to form a structural link between the molecular structure and gold nanorod.Type: GrantFiled: May 9, 2011Date of Patent: June 26, 2012Assignee: Arizonia Board of Regents for and on Behalf of Arizonia State UniversityInventors: Wayne D. Frasch, Lars Chapsky

Patent number: 8164618Abstract: A method for generating a video output signal. The method may include receiving a plurality of input video signals from each of the participants. Each of the input video signals may have a plurality of input frames. Each of the input frames may have a source slice carrying an image. Each of the input frames may be encoded using the respective reference frame at an encoding time. The method may include a step for generating the video output signal for transmission to the participants. The video output signal may comprise a plurality of output frames. A first of the output frames generally has at least a first slice having (a) a first coded portion carrying the image from a first of the participants and (b) a first unencoded portion for the image from a second of the participants. A second of the output frames generally has at least a second slice having (a) a second coded portion carrying the image from the second participant and (b) a second unencoded portion for the image from the first participant.Type: GrantFiled: February 13, 2009Date of Patent: April 24, 2012Assignee: Exedra Technology, LLCInventors: Chih-Lung Yang, Lars Chapsky
