Patent number: 11264920Abstract: The invention provides an energy generation system comprising a generator having charged mutually rotating plate elements, and comprising an integrated drive mechanism for precisely controlling a separation distance between the plates. The drive mechanism provides a separation which varies as a function of the speed of rotation, hence assimilating separation control within the natural operation of the device. Embodiments provide plates comprising self-generating bearings, both hydrodynamic gas and fluid bearings and centrifugal regulator solid bearings, the bearings providing a supporting force between the plates of a magnitude which increases as the rotational speed of the plates increases. Methods of energy generation are also provided.Type: GrantFiled: June 16, 2020Date of Patent: March 1, 2022Assignee: Koninklijke Philips N.V.Inventors: Steven Ernest Franklin, Lutz Christian Gerhardt, Willem Potze, Hans Kroes, Mark Thomas Johnson

Publication number: 20220049740Abstract: As gantry speeds experienced in CT scanners increase, so too does the radial load force exerted on components attached to the gantry. A self-lubricating sliding bearing used inside a rotary X-Ray source of a CT scanner is particularly susceptible to increasing radial load force, because in operation, a self-lubricating bearing floats on a film of liquid lubricant. Thus, the radial load force will tend to act on the floating portion of the bearing to develop an eccentricity in the longitudinal axis of the floating portion of the bearing as compared to the longitudinal axis of the stationary part of the bearing. The eccentricity will eventually cause the floating portion of the bearing to contact the stationary part of the bearing in operation, thus limiting the load carrying characteristic of the self-lubricating sliding bearing.Type: ApplicationFiled: September 10, 2019Publication date: February 17, 2022Inventors: CHRISTIAN HERBERT BLOME, WILLEM POTZE

Patent number: 10532172Abstract: A patient interface device uses a pressure flap which extends inwardly from an outer edge of a mask of the device. The pressure flap is for contacting the skin of the patient to provide a seal or partial seal between the mask volume and the ambient surroundings. The pressure flap includes a cavity area which is exposed to a reduced pressure compared to the mask volume. This assists in keeping the pressure flap pressed against the patient's skin, and thereby maintain a large contact area. This in turn gives a reduction in local high pressure areas.Type: GrantFiled: May 7, 2013Date of Patent: January 14, 2020Assignee: Koninklijke Philips N.V.Inventors: Rudolf Maria Jozef Voncken, Cornelis Petrus Hendriks, Nicolaas Petrus Willard, Mareike Klee, Joyce Van Zanten, Jacob Roger Haartsen, Willem Potze, Sima Asvadi

Patent number: 10094425Abstract: The present invention relates to hydrodynamic bearings, X-ray tubes, X-ray systems, and a method of manufacturing a hydrodynamic bearing for an X-ray tube. The rotor of a hydrodynamic bearing is supported, in steady-state operation, by the pressure of lubricant which is pumped through grooves in the rotor. When the rotor is speeding up or slowing down, the pumping force will not be sufficient to lift the rotor clear of a stationary bushing, and damage, caused by direct contact of the metal surfaces of the bearing, can occur. Providing special coatings on the bearing surfaces can ameliorate this effect.Type: GrantFiled: April 1, 2015Date of Patent: October 9, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Peter Klaus Bachmaan, Anand Kumar Dokania, Wilhelmus Cornelis Keur, Gereon Vogtmeier, Willem Potze, Christian Herbert Blome

Patent number: 10046131Abstract: A patient interface and a patient interface system comprise a responsive material and a method for preventing the formation of red marks due to wearing a patient interface that is pressing against the skin of a patient for a longer time and/or for reducing air leakages of the patient interface that may result from an unintended shift of the patient interface on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element on the patient and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.Type: GrantFiled: June 6, 2013Date of Patent: August 14, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Cornelis Petrus Hendriks, Susanne Maaike Valster, Marc Matysek, Sander Theodoor Pastoor, Roland Alexander Van De Molengraaf, Nicolaas Petrus Willard, Richard Johannus Maria Van De Ven, Joyce Van Zanten, Willem Potze, Sima Asvadi, Rudolf Maria Jozef Voncken, Jacob Roger Haartsen, Mareike Klee, Matthew John Lawrenson, Julian Charles Nolan
