Patents by Inventor Christopher Chase

Christopher Chase has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260113284
    Abstract: A resource allocation network data store data store contains information about a plurality of resource allocations. Each allocation is associated with a multi-level hierarchical resource identifier. A pre-processing cache periodically retrieves information from the resource allocation network data store, pre-aggregates the information for multiple combinations of selectable analysis options, and stores the pre-aggregated data. An analysis server receives an analysis initiation request (including a plurality of selected analysis options) from a network point. The server then determines a first value of resource amounts based on the selected analysis options, information in the cache, and allocation amounts for the network point initiating the analysis. The server also determines a second value of resource amounts based on allocation amounts for points including points other than the point initiating the analysis.

  • Patent number: 12514472
    Abstract: A glucose detection or monitoring system that includes a VCSEL laser with one or more active regions having quantum wells and barrier. The active regions are surrounded by one or more p-n junctions. The one or more active regions can include a selected shape structure, and one or more tunnel junctions (TJ). One or more apertures are provided with the selected shape structure, one or more buried tunnel junctions (BTJ) or oxide confine apertured, additional TJ's, planar structures and or additional BTJ's created during a regrowth process that is independent of a first growth process with a VCSEL output determined in response to a monitoring application of the VCSEL, the VCSEL having an HCG grating and a bottom DBR. A housing of a smartwatch interior houses the VCSEL laser. The smartwatch includes one or more of a display, an optical sensor, one or more electrodes, SIM card slot, speaker, microphone, charging pins, and a band.
