Patent number: 11856408Abstract: Methods of pairing devices wirelessly that include matching received-signal-strength information regarding signal-strength patterns received by differing devices desired to be paired. In some embodiments, signal-strength patterns are based on a user moving an object so as to intentionally create multipath Fresnel-zone propagation disturbances. During pairing, the devices exchange their received-signal-strength information with one another and compare the received-signal-strength information that they receive from another device to the received-signal-strength information that they generated themselves based on the multipath Fresnel-zone propagation disturbances. When the two sets of receive-signal-strength information substantially match one another, the devices determine the presence of a trusted relationship. Methods for assisting with the wireless pairing are also disclosed.Type: GrantFiled: October 29, 2021Date of Patent: December 26, 2023Assignee: Trustees of Dartmouth CollegeInventors: Timothy J. Pierson, Jonathan F. Alter

Patent number: 11786283Abstract: 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.Type: GrantFiled: May 23, 2022Date of Patent: October 17, 2023Assignees: Dartmouth-Hitchcock Clinic, The Trustees of Dartmouth CollegeInventors: Matthew C.
