Patent number: 9591996Abstract: A system and method are described herein for detecting a user's transition between sitting and standing postures. Transitions between sitting and standing states are reliably detected using an accelerometer attached to the user. By modeling error introduced by the accelerometer, and correcting for this error, transitions between sitting and standing states are reliably detected. A microprocessor coupled to the accelerometer converts the captured accelerometer data to approximate vertical acceleration. Vertical velocity, which includes accelerometer error, is determined from the approximate vertical acceleration. The vertical velocity is corrected, and the corrected vertical velocity used to determine vertical displacement. Transitions between sitting and standing states are determined from the vertical displacement.Type: GrantFiled: June 7, 2013Date of Patent: March 14, 2017Assignee: Lumo BodyTech, IncInventors: Andrew Robert Chang, Andreas Martin Hauenstein

Patent number: 9517027Abstract: An advancement mechanism of a lancing device operates to sequentially advance lancets in a cartridge. The advancement mechanism includes a rotary drive gear assembly with a first gear and a second gear that co-rotate in a first angular direction by operation of an inter-gear unidirectional drive mechanism such as a ratcheting mechanism. A second-gear unidirectional lock mechanism, such as a ratcheting mechanism, locks the second drive gear from co-rotating with the first drive gear in a second opposite angular direction without impeding rotation in the first direction. The second gear directly or indirectly rotationally drives a pinion gear, which rotationally drives a cartridge gear to advance the lancets in indexed increments for use. The first drive gear is rotated in the first and second directions by a rack gear of a translating operating handle. In addition, a rotary-gear cap-displacement mechanism and a rotary-gear charging/actuation mechanism are provided in other embodiments.Type: GrantFiled: September 28, 2010Date of Patent: December 13, 2016Assignee: FACET TECHONOLOGIES, LLCInventors: Gil Kan, Brian M.
