Publication number: 20210287416Abstract: An exemplary character interaction system located at a first site receives character behavior data representative of captured behavior of a real-world performer located at a second site. Based on the character behavior data, the system presents, to an interactive user at the first site, a representation of a virtual character avatar that performs, in real-time synchrony with the real-world performer at the second site, the captured behavior of the real-world performer. During this presentation of the virtual character avatar, the system provides user video data representative of captured behavior of the interactive user for presentation to the real-world performer to allow the real-world performer to interact in real time with the interactive user via the virtual character avatar. The system also generates an augmented representation of an interaction between the virtual character avatar and the interactive user for presentation to a non-interactive observer.Type: ApplicationFiled: March 13, 2020Publication date: September 16, 2021Inventors: Colleen Elizabeth O'Hagan, Benjamin Michael Roffee, Ian Nelson, Patrick Ian Moss, Alastair D Macleod, Kevin Gorgonia, Adnan Nabeel Ghani, Eric Day

Patent number: 6868099Abstract: A high power diode laser system utilizes an external cavity to narrow the spectral width of a high power multimode diode laser to change the output power normally produced by the diode from a broad spectrum to a very narrow spectrum. The power output of the laser system is concentrated over a narrow spectral range which falls within the useable range for particular applications, such as optical pumping of noble gas samples for magnetic resonance imaging. The output of the diode is received by a collimating element which directs the light on a beam path to a diffraction grating which is oriented at an angle to the incident beam. A portion of the beam may be directed from the diffraction grating to provide useable output light, and a portion of the light incident on the grating is directed back to be focused on the diode to provide feedback to cause the diode to preferentially lase at the wavelength of the light that is fed back.Type: GrantFiled: November 3, 2000Date of Patent: March 15, 2005Assignee: Wisconsin Alumni Research FoundationInventors: Thad G.
