  • Publication number: 20220262561
    Abstract: In one aspect, described is a magnetic-core inductor design approach that leverages NiZn ferrites with low loss at RF, distributed gaps and field balancing to achieve improved performance eat tens of MHz and at hundreds of watts and above. Also described is an inductor design which achieves “self-shielding” in which the magnetic field generated by the element is wholly contained within the physical volume of the structure rather than extending into space as a conventional air-core inductor would. This approach enables significant reductions of system enclosure volume and improvements in overall system efficiency.

  • Patent number: 11406290
    Abstract: Systems and methods for monitoring a range of motion of a joint are described. For example, in one embodiment, a first set of sensors may sense accelerations of a first body portion located on a first side of the joint and a second set of sensors may sense accelerations of the second body portion located on a second opposing side of the joint. The acceleration data may then be used to compute the relative motion of the first and second body portions to determine movement of the joint. This joint movement may then be used to determine one or more range of motion movement metrics which are output for viewing by a subject or medical practitioner.

  • Patent number: 11337744
    Abstract: A system and method for installation of a k-wire through a scaphoid or other fractured bone can include a guide block for accurate trajectory of a k-wire. A support frame for a guide block can be casted and/or secured into place, and a CT scan is obtained, so the fractured bone and the location of the window can be known in the same three-dimensional space. An ideal k-wire trajectory can be plotted through the fractured bone, and a guide block with a lumen can be designed and printed using a three-dimensional printer. The guide block can be inserted into the frame so the lumen aligns with the ideal k-wire trajectory, and a k-wire can be inserted through the lumen into the fractured bone. The net effect would be ideal placement of the k-wire that would facilitate the ultimate insertion of a percutaneous screw to provide fixation of the fractured bone.

  • Patent number: 11307656
    Abstract: View-through sensors each locatable proximate to an eye of a user and for use while the user is engaged in viewing activity. Each view-through sensor has a view-through region that allows the user to view through the sensor. An active peripheral region at least partially surrounds the view-through region and includes multiple light-sensing regions for sensing light reflected from an eye. In some embodiments, the view-through sensor is configured to use environmental light for eye tracking. When the view-through sensor uses environmental light, spatial and temporal information about the intensity of the environmental light can be used to enhance eye-tracking performance. This information can be obtained, for example, from light-sensing regions on the reverse side of the view-through sensor, from an electronic display, or from a forward-facing camera. In some embodiments, the view-through sensor includes light-emitting regions that emit the light that the sensor uses to track eye movement.

  • Patent number: 11153026
    Abstract: Apparatuses that provide for secure wireless communications between wireless devices under cover of one or more jamming signals. Each such apparatus includes at least one data antenna and at least one jamming antenna. During secure-communications operations, the apparatus transmits a data signal containing desired data via the at least one data antenna while also at least partially simultaneously transmitting a jamming signal via the at least one jamming antenna. When a target antenna of a target device is in close proximity to the data antenna and is closer to the data antenna than to the jamming antenna, the target device can successfully receive the desired data contained in the data signal because the data signal is sufficiently stronger than the jamming signal within a finite secure-communications envelope due to the Inverse Square Law of signal propagation. Various related methods and machine-executable instructions are also disclosed.

  • Publication number: 20210220665
    Abstract: While clinical treatment of actinic keratosis by photodynamic therapy (PDT) is widely practiced, there is well-known variability in response, primarily caused by heterogeneous accumulation and PDT-induced photobleaching of the photosensitizer protoporphyrin IX (PpIX) between patients and between lesions. One of the key factors in regularizing this treatment would be to have an easily accessible indicator of PpIX present in the lesions at the time of light delivery. Described herein, a smartphone-based fluorescence imager was developed to allow simple quantitative photography of the lesions and their PpIX levels.
