  • Patent number: 11955966
    Abstract: An analog input device including at least one mounting panel and a matrix of analog push button assemblies mounted thereon. Each analog push button assembly including an analog pressure sensor including a pressure reception arrangement having an optical sensing sub-arrangement configured to measure an amount of light varied according to a pressure sensed at the pressure reception arrangement and an output terminal for outputting an analog signal corresponding to the amount of light measured, and a plunger element configured to exert the pressure on the pressure reception arrangement. The analog input device may include a multiplexer including an input side coupled to the push button assemblies and an output side; an analog-to-digital converter coupled to the output side of the multiplexer; a processor coupled to the analog-to-digital converter and configured to output a data packet; and a communication interface configured to transmit the data packet to a host computing device.

  • Publication number: 20240026270
    Abstract: The present invention is directed to a method of making a live cell construct or a support, comprising: (a) providing a non-cellular organic polymer support having a top surface, a bottom surface, and an intermediate portion there between, and (b) contacting a cross-linking agent to one surface of said support for a time sufficient to generate a gradient of cross-linking of said polymer in said intermediate portion. Also provided are live cell constructs, supports, and methods of use of the supports and live cell constructs.

  • Patent number: 11566213
    Abstract: A microfabricated device having at least one gas-entrapping feature formed therein in a configuration that entraps air bubbles upon wetting the feature with a solvent or solution is described. The device includes a sacrificial residue in contact with the gas-entrapping feature, the dissolution of which guides the wetting of the gas-entrapping feature.

  • Publication number: 20220288452
    Abstract: Aspects are directed to visual support for exercise compliance including capturing, via a camera of a user device, images of a first person performing one or more motions. Previously recorded images of a second person performing the one or more motions are accessed via the user device. Combined images are created by overlaying the images of the first person performing the one or more motions on the images of the second person performing the one or more motions. The combined images are output via a display device.

  • Patent number: 11193110
    Abstract: A method of making a live cell construct is carried out by: (a) providing a non-cellular support having a top surface and a bottom surface, (b) contacting live undifferentiated cells to the non-cellular support, and then (c) propagating a gastrointestinal epithelial cell monolayer on said top surface. In some embodiments, the live cells in the monolayer include: (i) undifferentiated cells (e.g., stem or progenitor cells); and (ii) optionally, but in some embodiments preferably, differentiated cells (e.g., enterocytes, Paneth cells, enteroendocrine cells, tuft cells, microcells, intra-epithelial lymphocytes, and/or goblet cells). Constructs formed by such methods and methods of using the same (e.g., in high through-put screening) are also described.

  • Patent number: 11046926
    Abstract: An apparatus for collecting or culturing cells or cell colonies includes: a common substrate formed from a flexible resilient polymeric material and having a plurality of wells formed therein; and a plurality of rigid cell carriers releasably connected to said common substrate, with said carriers arranged in the form of an array, and with each of the carriers resiliently received in one of the wells. A method of collecting or culturing cells or cell colonies with such an apparatus is carried out by depositing a liquid media carrying cells on the apparatus so that said cells settle on or adhere to said the carriers; and then (c) releasing at least one selected carrier having said cells thereon by gradual application of release energy to each carrier from the cavity in which it is received (e.g., by pushing with a probe).
