  • Publication number: 20240367137
    Abstract: A method of registering a location of a dispenser array in relation to a microfluidic array is provided. One of the dispenser array and the microfluidic array can be movable in relation to the frame, and the other can be fixed relative to the frame. Their relative positions can be identified by a set of coordinates. Identification of a fiducial marker can occur in a manner permitting the fiducial reference to appear in a first position of a field of view of a first camera when the dispenser array or the microfluidic array is in an alignment position. Quantities related to a vector displacement from the alignment position to a fixed position on the microfluidic array or the dispenser array can be identified. Quantities determined can be used to guide positioning of the dispenser array relative to the microfluidic array.

  • Patent number: 11154834
    Abstract: A differentially coated device for conducting a plurality of nano-volume specified reactions, the device comprising a platen having at least one exterior surface modified to a specified physicochemical property, a plurality of nano-volume channels, each nanovolume channel having at least one interior surface in communication with the at least one exterior surface. Methods for preparing and using such devices are also provided, as well as a method of registering a location of a dispenser array in relation to a microfluidic array. Quantities related to a vector displacement from the alignment position to a fixed position on the one of the dispenser array and the microfluidic array is determined. The quantities thus determined are used to guide positioning of the dispenser array relative to the microfluidic array.

  • Patent number: 10056078
    Abstract: Speech-controlled searching and browsing for content using speech-controlled devices, or other input-limited devices, is described. A user may audibly indicate to a speech-controlled device whether the user wants to search or browse for content, along with a topic of the content/results to be retrieved. A server, located remotely from the speech-controlled device determines an appropriate endpoint device for displaying results of the requested search or browse. The server also determines an appropriate content source for the requested content, and sends a request for the content to the content source. The server receives search or browse results from the content source and forwards them to the determined endpoint device.
