Abstract: Described herein are electrode active materials useful as the positive electrode in lithium or lithium-ion batteries. The disclosed electrode active materials comprise lithium phosphates uniquely suited for mixing with lithium layered oxides, as well as the resulting mixture. For example, compositions of matter are described herein. The disclosed materials exhibit high energy density with reduced cobalt and nickel content.

Abstract: Techniques for processing lithium-ion cathode active materials, such as cathode active materials comprising lithium-based materials, such as lithium metal oxide materials (e.g., lithium transition metal oxide materials) are provided. The techniques process the lithium-ion cathode active materials after an initial preparation step to remove residual lithium species, such as lithium hydroxide and/or lithium carbonate, present in the lithium-ion cathode active materials. Cathode materials comprising low residual lithium species are also described, as well as cathodes and batteries comprising such cathode materials.

Abstract: A system includes: an objective lens; a first light source to feed first illuminating light through the objective lens and into a flowcell (e.g., with a relatively thin film waveguide) to be installed in the system, the first illuminating light to be fed using a first grating on the flowcell; and a first image sensor to capture imaging light using the objective lens, wherein the first grating is positioned outside a field of view of the first image sensor. Dual-surface imaging can be performed. Flowcells with multiple swaths bounded by gratings can be used. An auto-alignment process can be performed.

Abstract: The disclosure provides for structured illumination microscopy (SIM) imaging systems. In one set of implementations, a SIM imaging system may be implemented as a multi-arm SIM imaging system, whereby each arm of the system includes a light emitter and a beam splitter (e.g., a transmissive diffraction grating) having a specific, fixed orientation with respect to the system's optical axis. In a second set of implementations, a SIM imaging system may be implemented as a multiple beam splitter slide SIM imaging system, where one linear motion stage is mounted with multiple beam splitters having a corresponding, fixed orientation with respect to the system's optical axis. In a third set of implementations, a SIM imaging system may be implemented as a pattern angle spatial selection SIM imaging system, whereby a fixed two-dimensional diffraction grating is used in combination with a spatial filter wheel to project one-dimensional fringe patterns on a sample.

Abstract: A computer vision dating system analyzes combinations of face features of the system's user's photographs and recommends potential dating partners. A user selects preferred and not-preferred faces from a sample of other user's pictures. The system analyzes the features of the preferred and not-preferred faces comparing the combinations of features in both categories with the features of other users in the database to find the users that most match the collective features preferred by the user. These pictures are presented to the user. Data from the user's profile input are analyzed to automatically generate the sample pictures from which the user selects his/her preferences. As the users are presented pictures after their sample selection, they can continue to select and reject pictures allowing the system to learn and refine the combinations of features and better locate those that most conform to a user's most preferred photo images.
