Patent number: 10481682Abstract: An electronic system generates at a display virtual writing corresponding to tracked motion of the tip of a pointer with respect to a surface based on proximity of the tip of the pointer to the surface and the gaze of a user's eye. The electronic system determines the location and motion of the tip of the pointer with respect to the surface based on images captured by scene cameras, and determines the focus and gaze direction of the user's eye based on images captured by a user-facing camera. By generating virtual writing at the display corresponding to tracked motion of the tip of the pointer based on proximity of the tip of the pointer to the surface and based on the focus and gaze direction of the user's eye, the electronic system can enable virtual writing and associated collaboration services without the need for a specialized writing surface or pointer.Type: GrantFiled: March 29, 2017Date of Patent: November 19, 2019Assignee: GOOGLE LLCInventors: Lewis James Marggraff, Nelson G.

Publication number: 20140378675Abstract: The invention provides novel oligonucleotides and methods of using the same for detection or measurement of specific nucleic acid molecules. The invention also features nucleic acid arrays comprising the oligonucleotides of the invention. An oligonucleotide of the invention comprises (1) a reporter-binding sequence capable of hybridizing to a fluorophore-labeled reporter sequence and (2) a hairpin-forming sequence capable of forming a stem-loop. Formation of the stem-loop modifies (e.g., quenching) the fluorescence signals of the reporter sequence when the reporter sequence is hybridized to the oligonucleotide. This can be achieved, for example, by bringing one or more guanine based in the oligonucleotide into close proximity to the fluorophore(s) of the reporter sequence by virtue of the formation of the stem-loop. Disruption of the stem-loop, such as by hybridization of a target sequence to at least part of the hairpin-forming sequence, produces a detectable change in the fluorescence signals.Type: ApplicationFiled: September 5, 2014Publication date: December 25, 2014Applicant: Board of Regents of the Nevada System of Higher Education, on behalf of the University of NevadaInventors: Suk-Wah Tam-Chang, Kenneth W.
