Abstract: An oral care device has a field generator adapted to generate an electric field in a mouth of a user, responsive to an input control signal. The electric field is for imparting a force upon particles forming a biofilm to be removed by the oral care device or upon cleaning agent particles. A cyclic control signal is generated for intermittent generation of an electric field at a first RF frequency. The use of an intermittent generation of an RF electric field means the force applied to particles (in particular polarized particles) by the field is itself cyclic. The cyclic nature of this applied force is found to be more effective in the disintegration of a biofilm to be removed, and hence makes subsequent mechanical removal, e.g. by brushing, easier.

Abstract: The present invention relates to body fluid monitoring. It is proposed to incorporate a reagent-free calibration method into a patch or wearable.

Abstract: The invention provides a mouthpiece for dental cleaning system and the dental cleaning system itself. The mouthpiece has a base and inner and outer arches. An actuator is for applying motion to the inner arch and/or the outer arch, relative to the base. A coupling arrangement converts motion of one of the inner and outer arches in one direction relative to the base to motion in an opposite direction relative to the base of the other of the inner and outer arches. By forming the mouthpiece as a central stationary base enveloped by two contour-following and moving arches, an anti-phase brushing motion at opposite tooth sites along the tooth arch is enabled, giving increased reach toward the molars as well as a reduction in device vibration in the mouth.

Abstract: A monitoring system includes an implantable intra-vascular support device for positioning against a vessel wall and an implantable sensor-actuator mounted to the support device. The sensor-actuator is drivable between a non-deployed position in which it is against the support device and a deployed position in which it is displaced away from the support device. Sensor signals are generated when in the deployed position. This system is able to monitor flow away from the edge of a vessel by deploying the sensor-actuator towards the center of the vessel. When flow monitoring does not need to take place, it can be non-deployed so that it does not present an occlusion to the flow.
