Patent number: 10925655Abstract: Bone reduction forceps provide both continuous and discrete adjustment of force. A worm gear rotatably attached to one arm of the forceps engages a rack attached to another arm of the forceps to provide both the continuous and discrete force adjustment. Buttress threads on the worm and/or the rack allow for rapid closure by squeezing the handles of the forceps. Rotating the worm gear allows for fine adjustment of closing force. A five-bar linkage provides increased mechanical advantage and an extra degree of freedom, compared to conventional forceps. Interchangeable tips provide flexibility, allowing a user to customize the forceps to a task or the user's preferences.Type: GrantFiled: July 6, 2017Date of Patent: February 23, 2021Assignee: Massachusetts Institute of TechnologyInventors: Alexander Henry Slocum, James Francis Connor, Jr., Jacob Alexander Mooney, Nicholas Wing-Ping Kwok

Patent number: 8881594Abstract: A pressure measuring device includes a resilient expandable pressure sensor element having an open end and an opposite closed end. The pressure sensor element includes spiral flutes extending between the open and closed ends defining spiral bellows. The pressure sensor element is tapered over at least a portion of its length from the open end to the closed end. The pressure measuring device also includes a supporting structure having a pressure indicating scale. The supporting structure holds the pressure sensor element such that the open end of the pressure sensor element is in communication with a fluid whose pressure is to be measured and pressure applied by the fluid causes the pressure sensor element to expand axially and be visibly displaced relative to the pressure indicating scale by a distance related to the pressure applied by the fluid.Type: GrantFiled: January 17, 2012Date of Patent: November 11, 2014Inventors: Alexander Henry Slocum, Alexander H. Slocum, Jr.

Publication number: 20140069723Abstract: A method or corresponding apparatus in an example embodiment of the present invention relates to penetrating a particulate substrate using a compact, lightweight, low-energy, reversible, and dynamic device for burrowing through particulate substrates. In one preferred embodiment, the apparatus includes at least one vessel and a displacement module coupled with the vessel. The actuation of the displacement module fluidizes the particulate substrate proximate to the vessel and thereby reduces resistance of the particulate substrate to movement of the vessel and causes further penetration of the apparatus through the particulate substrate. The example embodiment utilizes volume contraction and localized fluidizing to efficiently move through substrates.Type: ApplicationFiled: July 29, 2013Publication date: March 13, 2014Applicant: Massachusetts Institute of TechnologyInventors: Amos Greene Winter, V, Anette E.

Patent number: 8397577Abstract: A system for measuring and indicating pressure that uses as its pressure sensing element an outer resilient tube, an inner resilient tube, and a rolling diaphragm connecting the inner and outer tubes, and held inside a protective enshrouding structure where pressure applied to the annulus between the tubes causes the diaphragm to deform and roll to axial extend the outer tube by an amount proportional to the applied pressure. The structure has features that enable visual correlation of the partially rolled tube's unrolled state with the applied pressure. The system can be incorporated into a syringe to create a pressure measuring syringe for inflating endotracheal cuffs while providing a reading of the cuff pressure.Type: GrantFiled: March 6, 2011Date of Patent: March 19, 2013Inventors: Alexander Henry Slocum, Sr., Alexander Henry Slocum, Jr.
