Publication number: 20230218376Abstract: An oral care device (8) adapted to generate an RF field for performing an oral cleaning function. The device includes a cleaning unit (10) for receipt in the mouth which includes a conductor arrangement (18, 19) which is driven with a drive signal to generate an RF field which cleans surfaces in the mouth. Means is further provided for sensing an electrical or electromagnetic signal arising from interaction of the RF energy with bodies in the mouth, for performing a sensing function with the same RF system components used for generating the RF field for cleaning or treatment.Type: ApplicationFiled: May 20, 2021Publication date: July 13, 2023Inventors: Lutz Christian GERHARDT, Neil Francis JOYE, Mark Thomas JOHNSON, Achim Rudolf HILGERS, Amir Hussein RMAILE

Patent number: 11564582Abstract: 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.Type: GrantFiled: December 14, 2018Date of Patent: January 31, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Cornelis Petrus Hendriks, Mark Thomas Johnson, Achim Rudolf Hilgers, Franciscus Johannes Gerardus Hakkens, Daan Anton Van Den Ende, Manfred Müller, Arjen Van Der Horst

Publication number: 20220149264Abstract: An actuator device has an ionic electroactive material actuator unit includes a unitary membrane with first and second actuation electrodes on the unitary membrane. A DC drive signal is applied between the actuation electrodes to cause migration of charges from one part of the unitary membrane towards another part of the unitary membrane. In addition, a pair of closely spaced measurement electrodes is provided on the first surface of the unitary membrane. In particular, the measurement electrodes are spaced apart by a spacing which is less than ten times the thickness of the unitary membrane at a location between the measurement electrodes. A local surface-effect impedance change is used as the basis of a signal measurement, for providing feedback relating to the state of actuation of the device.Type: ApplicationFiled: January 17, 2020Publication date: May 12, 2022Applicant: KONINKLIJKE PHILIPS N.V.Inventors: Eduard Gerard Marie Pelssers, Mark Thomas Johnson, Daan Anton Van Den Ende, Achim Rudolf Hilgers

Publication number: 20210046219Abstract: An implantable device includes an EAP actuator and a sensor. The sensor is configured to monitor a force external to the implantable device acting in a direction either with or counter to a direction of actuation of the actuator, and a controller is adapted to control the actuator to actuate at a moment when force counter to the direction of actuation is sensed to be at its lowest within a given time window or force with the direction of actuation is sensed to be at its highest within a given time window. In this way, actuation is effected at a moment of least resistance force, reducing the power needed for deployment of the actuator, and permitting actuation to occur even in conditions experiencing large variable forces.Type: ApplicationFiled: February 5, 2019Publication date: February 18, 2021Inventors: Cornelis Petrus Hendriks, Mark Thomas Johnson, Alexander Franciscus Kolen, Marjolein Irene Van Lieshout, Achim Rudolf Hilgers, Arjen Van Der Horst

Publication number: 20210020822Abstract: An actuator device comprises an actuator member (62) which incorporates an electroactive polymer material. A controller (72) controls supply of an actuation signal and a superposed AC signal, which has the effect of inducing heating. The actuator member has a known set of deformation or deflection responses to applied actuation signals of different levels, and a known set of oppositely direction deformation or deflection responses to applied AC signals of different levels. To achieve accelerated actuation response, an actuation signal is supplied of higher signal level than known to be necessary to realize a given desired actuation level, and an AC signal is supplied of a level sufficient to reduce the resultant actuation response to the desired level. In examples, the overdrive part of the actuation signal and the AC signal may be tapered off after realizing the desired actuation level.Type: ApplicationFiled: March 20, 2019Publication date: January 21, 2021Inventor: Achim Rudolf Hilgers

Publication number: 20210007610Abstract: A monitoring system comprises an intra-vascular support device and a sensor mounted to the support device and projecting into the vessel. The sensor generates a signal which is dependent on the level of deformation of a free end. The sensor signal is interpreted to enable detection of changes in the length of a deformable part of the sensor thereby to determine a level of bio-layer formation and also determine a level of flow. The sensor remains able to detect flow even when a bio-layer is formed and it can also detect the presence (and thickness) of the bio-layer, because part of the sensor becomes rigid when constrained by the bio-layer.Type: ApplicationFiled: March 15, 2019Publication date: January 14, 2021Inventors: Cornelis Petrus Hendriks, Achim Rudolf Hilgers, Manfred Mueller, Arjen Van Der Horst, Mark Thomas Johnson, Franciscus Johannes Gerardus Hakkens, Daan Anton Van Den Ende

Publication number: 20200405163Abstract: A blood pressure monitoring system is for mounting around a body limb or digit, in which an array of electroactive material actuators provides an inward force. One or more electroactive material actuators are identified which are best located for performing blood pressure monitoring and these are then used to apply a pressure. By performing pulse monitoring while controlling the identified one or more electroactive material actuators, the blood pressure may be determined.Type: ApplicationFiled: March 6, 2019Publication date: December 31, 2020Inventors: Achim Rudolf Hilgers, Kiran Hamilton J. Dellimore

Publication number: 20200345246Abstract: A system for determining a pulse wave velocity comprises a body lumen insertable device with an actuator for providing a pulse in the vicinity of a vessel wall and a sensor for sensing arrival of the pulse. A pulse wave velocity is obtained from the time difference between actuation of the actuator and sensing of the pulse. This system is used to create an artificial pulse which is transmitted along a vessel by a known distance before detection by a sensor.Type: ApplicationFiled: November 22, 2018Publication date: November 5, 2020Applicant: KONINKLIJKE PHILIPS N.V.Inventors: Achim Rudolf Hilgers, Cornelis Petrus Hendriks, Marjolein Irene Van Lieshout, Gerhardus Wilhelmus Lucassen, Eduard Gerard Marie Pelssers, Mark Thomas Johnson, Daan Anton Van Den Ende
