  • Patent number: 11940775
    Abstract: A method for creating metadevices includes receiving, at a computing device, one or more boundary conditions for a metadevice. The method also includes processing, with an inverse-design algorithm stored in a memory of the computing device, the one or more boundary conditions to generate a metadevice structure design that satisfies the one or more boundary conditions. The method also includes converting, by a processor of the computing device, the metadevice structure design into a file that is compatible with an additive manufacturing device. The method further includes providing the file of the metadevice structure design to the additive manufacturing device.

  • Patent number: 11850029
    Abstract: Representative methods, apparatus and systems are disclosed for blood pressure and other vital sign monitoring using arterial applanation tonometry, including ambulatory blood pressure and other vital sign monitoring. A representative system comprises a wearable apparatus. The various embodiments measure blood pressure and other vital sign monitoring using a plurality of pressure sensors of a pressure sensor array, with one or more of the pressure sensors 140 applanating an artery, such as a radial artery. In a first embodiment, a pressure sensor signal is utilized which has the highest cross-coherence with the signals of its nearest pressure sensor neighbors of the pressure sensor array. In a second embodiment, Kalman filtering is utilized for the pressure sensor signals from the pressure sensor array.
