  • Patent number: 11460607
    Abstract: An apparatus includes a substrate, a first patterned layer, and a second patterned layer. The first patterned layer may be coupled to the substrate and may have a first metasurface pattern. The second patterned layer disposed separately from the substrate and the first patterned layer, and may have a second metasurface pattern. Movement of the first patterned layer relative to the second patterned layer may be controllable via control circuitry such that a gap distance of a gap between the first patterned layer and the second patterned layer is changed to cause a transmittance for radiant energy of a selected wavelength passing through the apparatus to change from a first transmittance value to a second transmittance value.

  • Patent number: 11459619
    Abstract: A method for identifying a predefined target organism includes extracting a nucleic acid from a sample to form an extracted nucleic acid, amplifying the extracted nucleic acid to form a nucleic acid amplicon, tagging the nucleic acid amplicon with a capture probe and a detector partner to form a detector partner-nucleic acid amplicon-capture probe complex, and performing a detection assay on the detector partner-nucleic acid amplicon-capture probe complex to identify whether the predefined target organism is present in the sample.

  • Patent number: 11459611
    Abstract: The identification of mutations that are present in a small fraction of DNA templates is essential for progress in several areas of biomedical research. Though massively parallel sequencing instruments are in principle well-suited to this task, the error rates in such instruments are generally too high to allow confident identification of rare variants. We here describe an approach that can substantially increase the sensitivity of massively parallel sequencing instruments for this purpose. One example of this approach, called “Safe-SeqS” for (Safe-Sequencing System) includes (i) assignment of a unique identifier (UID) to each template molecule; (ii) amplification of each uniquely tagged template molecule to create UID-families; and (iii) redundant sequencing of the amplification products. PCR fragments with the same UID are truly mutant (“super-mutants”) if ?95% of them contain the identical mutation.

  • Publication number: 20220310243
    Abstract: An implant customization platform may receive image data associated with a bone of a patient. The implant customization platform may convert the image data to a structural representation of the bone. The implant customization platform may identify, based on the structural representation, a placement for an orthopaedic implant relative to the bone. The implant customization platform may determine a performance characteristic for a combination of the bone and the orthopaedic implant. The implant customization platform may determine, using an implant customization model, a data representation of the orthopaedic implant based on the structural representation, the placement, and the performance characteristic. The implant customization platform may perform an action associated with the data representation to permit the orthopaedic implant to be formed.

  • Publication number: 20220304897
    Abstract: A gastric drainage device includes a tube with a drainage lumen and a hub to receive an inflation device. The tube includes an intragastric portion having a set of holes to permit gastrointestinal contents to pass from a stomach cavity into the drainage lumen. The gastric drainage device includes a bolster with a cylindrical port to receive the tube and a disc to hold the tube in place on a skin side of a gastrostomy site. The gastric drainage device includes a balloon formed around the intragastric portion of the tube, wherein the balloon and the intragastric portion of the tube may be passed through the gastrostomy site into the stomach cavity while the balloon is deflated. Accordingly, the balloon is inflatable within the stomach cavity using the inflation device to secure the gastric drainage device at the gastrostomy site while the gastrointestinal contents are drained from the stomach cavity.

  • Patent number: 11452193
    Abstract: Some embodiments present wearable devices that communicate with other like devices via wireless signals and respond to them based on criteria that the wearer controls. According to some embodiments, the wearable devices are bracelets that allow wearers to identify, primarily by way of multicolored light displays, others based on specific criteria relating to an event or specific need. These criteria are also useful for allowing the bracelets to be controlled by a single coordinator who creates an event for the wearers to opt into (e.g. the arena manager at a sports game, the emcee at a wedding, the coordinator of a meet and greet event, etc.).
