Patent number: 10551195Abstract: The invention relates to a portable device with improved sensor position change detection. It aims at detecting a change of position of a mobile device relative to a user and, based on this change of position, a change of orientation of the mobile device relative to the user. This allows, when the orientation of the mobile device suddenly changes relative to a user, to keep track of this change. This is particularly useful for position tracking techniques such as Pedestrian Dead Recognition (PDR), which rely on an iterative determination of the orientation of a mobile device relative to the user, and may be affected by a sudden and important change of this relative orientation.Type: GrantFiled: August 19, 2016Date of Patent: February 4, 2020Assignee: MoveaInventor: Antoine Lemarchand

Power efficient machine diagnostic monitoring using multiple vibration sensor wireless configuration
Patent number: 10551243Abstract: A wireless monitoring unit performs condition monitoring associated with a test point location of a host machine. The unit includes a high performance vibration sensor useful for monitoring the host machine for fault conditions and the like. The unit includes a second vibration sensor that has poorer metrological performance, but draws a comparatively insignificant amount of power from the battery. The second sensor takes a vibration measure periodically, which measure is processed to evaluate whether the machine is in a state eligible to undergo a health assessment. Diagnostic monitoring using the high performance vibration sensor is enabled only when the host machine it is in the eligible state. A low power temperature sensor provides additional data for guarding against a false trigger, in effect allowing the processor to distinguish against vibration from another machine propagating to the host machine causing the host machine to vibrate while the host machine is not running.Type: GrantFiled: November 28, 2016Date of Patent: February 4, 2020Assignee: ACOEM FranceInventors: Bertrand Wascat, Thierry Mazoyer, Patrick Labeyrie, Guillaume Lavaure, Philippe Poizat -
