Patent number: 9410593Abstract: A nodal-mounted spring arrangement for an electronic toothbrush includes a V-shaped spring member secured at both ends so that it can operate in out-of-phase torsion mode along the axial dimension thereof. In one embodiment, the V-shaped spring member includes two extended end regions, which extend below a longitudinal edge of the middle portion of the V-spring. The free ends of the extended portions are joined by a flat cross-piece. This “closed end” region is present at both ends of the V-spring.Type: GrantFiled: June 27, 2011Date of Patent: August 9, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Tyler G.

Patent number: 8418300Abstract: A workpiece system with a reciprocating motion which includes a motor assembly for producing an output drive signal with a periodic force pulse. The drive signal is coupled to a driven member assembly through a magnetic arrangement, wherein the driven member assembly has a workpiece mounted thereon with a return spring assembly. The driven member assembly has a resonant mechanical frequency. As the RPM of the motor increases from zero following startup, the drive signal frequency increases to the point very near resonance, where the energy from the drive signal is transferred into the reciprocating motion of the driven assembly, producing an effective amplitude of workpiece motion.Type: GrantFiled: June 30, 2006Date of Patent: April 16, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Kevin A.
