Patent number: 7954243Abstract: Hair cutting apparatus having at least one cutting unit (2) with a stationary cutting member (3) and reciprocable movable cutting member (4) each having cooperating bearing surfaces (7,8) with cutting edges (9,10). To minimize the friction between the bearing surfaces a visco-elastic element is provided between the coupling element (14) and the movable cutting member (4) resulting in a small cutting gap between the bearing surfaces. During cutting of hairs the visco-elastic element behaves as a stiff element whereas during periods in which no hairs are cut the element behaves relatively soft so that the cutting gaps between the cutting edges are closed.Type: GrantFiled: June 10, 2005Date of Patent: June 7, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Bastiaan Johannes De Wit, Fokke Roelof Voorhorst, Geert Veenstra

Publication number: 20110100944Abstract: The peristaltic teat is a cleanable teat which rewards the baby for making the same natural peristaltic tongue movement it makes at the mother's breast. The reward is that the baby gets (more) milk when making the correct movement. The consequence is that the baby will use the same drinking mechanism as at the breast. Hence bottle feeding will become closer to breast feeding which makes the combination of bottle feeding and breast feeding easier.Type: ApplicationFiled: July 2, 2009Publication date: May 5, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Johannes Tseard Van Der Kooi, Fokke Roelof Voorhorst

Patent number: 7698819Abstract: A shaving apparatus includes at least one cutting unit having an inner cutter rotationally drivable with respect to an outer cutter by driving shaft of a driving device. The driving shaft exerts a prestress force on the inner cutter in the direction of the outer cutter. During cutting of a hair, the hair exerts a cutting force on the inner cutter directed opposite the driving force. The driving shaft bears axially on the outer cutter via at least one driving surface of a coupling element which is rotationally drivable. The inner cutter includes at least one driven surface for cooperating with the driving surface for exerting the driving force. The direction of the driving force is substantially perpendicular to the driving surface and the driven surface.Type: GrantFiled: July 9, 2003Date of Patent: April 20, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Bastiaan Johannes De Wit, Simon Eme Kadijk, Fokke Roelof Voorhorst, Sieds Bosch

Publication number: 20090036795Abstract: In a technique for substance sampling and/or substance delivery via the skin barrier, the skin is domed and then a portion removed. Typically a contact portion of the apparatus effects doming of the skin and a cutting, grazing or scraping arrangement removes a portion of the domed skin. The doming of the skin and hence the skin removal is closely controlled. Samples may be taken via the removed portion of the skin and/or substances delivered therethrough.Type: ApplicationFiled: September 22, 2006Publication date: February 5, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Paulus Cornelis Duineveld, Fokke Roelof Voorhorst, Michel Allan Aurelius Schallig, Anke Sinnema
