Patent number: 10980624Abstract: A toothbrush (10) includes a brushhead (18), a first force sensor (30A) for measuring a first force exerted by the brushhead at a first angle relative to a tooth and a second force sensor (30B) for measuring a second force exerted by the brushhead at a second angle relative to the tooth, the second angle being different than the first angle, and a processing unit (26). The processing unit is structured to: (i) receive first information indicative of the first force as measured by the first force sensor, (ii) receive second information indicative of the second force as measured by the second force sensor, and (iii) determine information regarding a current brushing angle of the brushhead based on the first information and the second information.Type: GrantFiled: September 19, 2018Date of Patent: April 20, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Mark Thomas Johnson, Johannes Hendrikus Maria Spruit, Okke Ouweltjes, Edgar Martinus Van Gool, Menno Willem Jose Prins

A controller (225) processes signal readings sensed by the parameter sensor (P, P1 or P2) and determines whether the signal readings are indicative of a substance (116) obstructing the passage of fluid (130) through the open port of the distal tip (112, 112?) of a distal probe portion (110) of the detection apparatus (100, 100?, 100?, 100?a, 100?b, 100?c, 100?d, 100c). The controller (225) transmits a signal that changes dynamic pressure at the distal tip (112, 112?) upon determining that the signal readings are indicative of a substance (116) obstructing the passage of fluid (130) through the open port of the distal tip (112, 112?).Type: ApplicationFiled: January 21, 2015Publication date: November 24, 2016Inventors: MARK THOMAS JOHNSON, JOHANNES HENDRIKUS MARIA SPRUIT, MENNO WILLEM JOSE PRINS, STEVEN CHARLES DEANE, PIETER HORSTMAN, EDGAR MARTINUS VAN GOOL, OKKE OUWELTJES
