Patent number: 11860413Abstract: Described herein are photonic communication platforms that can overcome the memory bottleneck problem, thereby enabling scaling of memory capacity and bandwidth well beyond what is possible with conventional computing systems. Some embodiments provide photonic communication platforms that involve use of photonic modules. Each photonic module includes programmable photonic circuits for placing the module in optical communication with other modules based on the needs of a particular application. The architecture developed by the inventors relies on the use of common photomask sets (or at least one common photomask) to fabricate multiple photonic modules in a single wafer.

Publication number: 20230078133Abstract: A system for performing advanced spectrometry using a camera of a personal electronic device. Light from a sample is captured via a light dispersion device that diffracts the light in accordance with the wavelength of that light. A sample spectrum image is captured using a camera of a personal electronic device. Spectral data is extracted from the sample spectrum image and the spectral data is wavelength calibrated by mapping each pixel position in the sample spectrum image to a wavelength. Features are extracted from the wavelength calibrated spectral data and used by classification module, trained on a dataset of features extracted from spectral data of known samples, to classify the sample. In some embodiments, a calibration spectrum image captured from a calibration light source having a known spectrum (e.g., in the same image frame using a bifurcated fiber optic cable) is used to wavelength calibrate the spectral data.Type: ApplicationFiled: September 12, 2022Publication date: March 16, 2023Inventors: Richard John Koshel, Travis Sawyer, Justina Bonaventura, Thomas Graham Knapp

Publication number: 20230085600Abstract: A self-calibrating spectrometer that captures a sample spectrum image of a sample via a light dispersion device and a calibration spectrum image of a calibration light source having a known spectrum (e.g., in the same image frame using a bifurcated fiber optic cable). Spectral data is extracted from the sample spectrum image and wavelength calibrated by matching calibration spectral data extracted from the calibration spectrum image to the known spectrum of the calibration light source, mapping each pixel position of the calibration spectrum image to a wavelength of the known spectrum of the calibration light source, and mapping each pixel position of the sample spectral data to a wavelength based on the pixel position-to-wavelength mapping. In some embodiments, extracted features from the wavelength calibrated spectral data are used by classification module, trained on a dataset of features extracted from spectral data of known samples, to classify the sample.Type: ApplicationFiled: September 12, 2022Publication date: March 16, 2023Inventors: Richard John Koshel, Travis Sawyer, Justina Bonaventura, Thomas Graham Knapp

Patent number: 11550638Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reducing latency in presenting content. In one aspect, a system includes a native application that presents an interactive item and a latency reduction engine. The latency reduction engine detects interaction with the interactive item that links to a first electronic resource that is different from the native application and provided by a first network domain and in response to the detecting, reduces latency in presenting the first electronic resource, including executing a first processing thread and a second processing thread in parallel. The first processing thread requests a second electronic resource from a second network domain and loads the second electronic resource and, in response to the loading, stores a browser cookie for the second network domain. The second processing thread requests the first electronic resource and presents the first electronic resource.Type: GrantFiled: March 31, 2020Date of Patent: January 10, 2023Assignee: Google LLCInventors: Tuna Toksoz, Thomas Graham Price
