  • Patent number: 10551243
    Abstract: 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.

  • Patent number: 10551195
    Abstract: 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.

  • Patent number: 10539584
    Abstract: A CTS nozzle achieves the object of reducing rubber chips produced when the CTS nozzle is inserted into and extracted from a rubber plug of a sample container during dispensing of a sample, thereby inhibiting the wear of the tip of the CTS nozzle. The CTS nozzle has two cut surfaces at its tip, and the pressure applied from the rubber when the nozzle is inserted into the rubber plug is dispersed onto the two cut surfaces without being deflected onto one of the cut surfaces. The pressure applied to the nozzle due to the resilience of the rubber being pushed away by the nozzle is thus dispersed and the rubber chips produced by the friction between the cut surfaces of the nozzle and the rubber are reduced. As a result of the reduced friction, the wear of the tip of the nozzle is minimized.

  • Patent number: 10539643
    Abstract: Systems and methods that provide a portable, verified voltage source that allows safe testing of separate contact and non-contact voltage measurement devices. A proving unit of the present disclosure selectively provides a known or specified direct current (DC) voltage, a contact alternating current (AC) voltage, and a non-contact AC voltage, which voltages may be fixed or may be user-selectable. The proving unit may include a visual indicator and/or an audible indicator that provides the user with an indication confirming that the proving unit is supplying the selected output voltage within the specifications of the proving unit, so the user will know that the proving unit is operating normally and is ready for testing the operation of a contact or non-contact voltage measurement device. If the proving unit cannot provide the specified voltage output, the indicator(s) provides a signal to the user that the proving unit is currently non-functional.
