Patent number: 12110743Abstract: During extension, the reamer block of an expandable reamer pushes on an upper plate. Extension is limited by contact with a spring retainer. To adjust the maximum extension of the expandable reamer, a spacer is placed between the expandable block and the spring retainer. The spacer reduces the amount of longitudinal travel of the expandable reamer, thereby reducing the extension of the expandable reamer.Type: GrantFiled: January 5, 2024Date of Patent: October 8, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Stuart Johnston

Publication number: 20160220331Abstract: A method and apparatus for correcting Class II and Class III malocclusions is disclosed. More specifically, the described orthodontic bite corrector may be installed on multiple points of attachment, including an archwire or an orthodontic band. Preferably, the bite corrector is comprised of a coil spring wrapped around a push rod, the coil spring and a portion of the push rod being contained within a spring housing. A mechanism of attachment is also provided on both the rod and the housing. The mechanism of action is such that the majority of corrective forces are the result of spring expansion, rather than spring compression.Type: ApplicationFiled: February 2, 2015Publication date: August 4, 2016Inventor: Michael Stuart Johnston

Patent number: 8622738Abstract: An orthodontic brace system includes brackets having a diamond-shaped tie-wing configuration that defines two parallel, horizontal slots, each of which is adapted to receive an archwire. Each slot is angled with respect to the base of the bracket to produce a specific, maximum torque value, and generally, the maximum torque value of the gingival slot is less than the maximum torque value of the incisal slot. The brackets provide multiple force vectors in different directions simultaneously, which decreases the amount of time required for a patient to wear braces, reduces the number of costly and time consuming visits to an orthodontist, and reduces time and effort required of an orthodontist for installation and adjustment of the braces on a per visit basis. A self-ligating bracket with a sliding door is disclosed in another embodiment.Type: GrantFiled: December 7, 2012Date of Patent: January 7, 2014Inventor: Michael Stuart Johnston

Patent number: 8147420Abstract: An apparatus and method can be configured to detect respiratory air temperature information and respiratory air pressure information from a patient using a first piezoelectric film and a second piezoelectric film, wherein at least a portion of the second piezoelectric film overlaps at least a portion of the first piezoelectric film. In an example, the first and second piezoelectric films can be sized and shaped to be disposed on an upper lip of a subject. In certain examples, the first piezoelectric film can include a non-overlap portion exposed to nasal respiration, and the second piezoelectric film can include a non-overlap portion exposed to oral respiration.Type: GrantFiled: June 24, 2009Date of Patent: April 3, 2012Assignee: Dymedix CorporationInventors: Reinhold Henke, Evan Stuart Johnston, Alan Bradley Jones
