  • Patent number: 11678941
    Abstract: Medical software tools platform utilizes a surgical display to provide access to specific medical software tools, such as medically-oriented applications or widgets, that can assist those in the operating room, such as a surgeon or surgical team, with a surgery. In particular, an optical sensor located within an endoscopic camera may register the momentary change in the optical characteristics reflected from a tissue surface and in turn transmit the information to a medical image processing system which can also receive patient heart rate data and display relevant anomalies. Changes in various spectral components and the speed at which they change in relation to a source of stimulus (heartbeat, etc.) may indicate the arrival of blood, contrast agents or oxygen absorption. Combinations of these may indicate various states of differing disease or margins of tumors, and so forth. Also, changes in temperatures and the speed of change may indicate subsurface anomalies.

  • Patent number: 11678713
    Abstract: Presented are intelligent electronic footwear and apparel with controller-automated features, methods for making/operating such footwear and apparel, and control systems for executing automated features of such footwear and apparel. A method for operating an intelligent electronic shoe (IES) includes receiving, e.g., via a controller through a wireless communications device from a GPS satellite service, location data of a user. The controller also receives, e.g., from a backend server-class computer or other remote computing node, location data for a target object or site, such as a virtual shoe hidden at a virtual spot. The controller retrieves or predicts path plan data including a derived route for traversing from the user's location to the target's location within a geographic area. The controller then transmits command signals to a navigation alert system mounted to the IES's shoe structure to output visual, audio, and/or tactile cues that guide the user along the derived route.

  • Patent number: 11642070
    Abstract: A device and system for non-invasively measuring wavelength-dependent changes in optical absorption of brain tissue damaged by CTE, TBI, concussion, repetitive trauma, and/or Lou Gehrig's disease in comparison to signals from healthy normal tissue for a subject in vivo. The brain, tissues, and fluids superficial to the brain are trans-cranially illuminated by light source(s) in low-absorption spectral windows for tissue in the visible and/or near-infrared parts of the spectrum. Optode(s) are disposed at predetermined radial distance(s) from a light output to collect the scattered and/or deflected signal from the surface of the head. The predetermined radial distance from the light output to the optode is correlated with the depth of tissue penetration for the light collected by the optode. A spectrometer and computer analyze the collected light for characteristic optical signatures of the brain tissue damage utilizing the absorbance and/or reflectance and/or transmission spectra generated as a result.

  • Patent number: 11600093
    Abstract: Embodiments relate to a sensor system for a brain computer interface (BCI) that enable detection and decoding of brain activity by optical tomography. The sensor system includes an array of pixels arranged as grouped pixel units to provide increased dynamic range. One or more of the grouped pixel units can operate in a saturated mode while providing information useful for decoding brain activity. Furthermore, the grouped pixel units are arranged to enable fast readout by a pixel scanner, thereby increasing detection and decoding ability by systems implementing the sensor design. The grouped pixel units of the sensor system are aligned with optical fibers of an interface to a body region of a user, where the optical fibers can be retained in position relative to the grouped pixel units by an optically transparent substrate that provides mechanical support while minimizing factors associated with divergence of light transmitted through optical fibers.
