| 20100186179 | RECIPROCATING WORKPIECE DEVICE WITH A DRIVE SYSTEM SEEKING THE RESONANCE OF THE DRIVEN SYSTEM PORTION THEREOF - 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. | 07-29-2010 |

| 20100072684 | NODAL SPRING ASSEMBLY FOR AN ELECTRONIC TOOTHBRUSH - 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. A mounting plate is connected between a node point along the V-shaped spring member and the housing of the toothbrush. In one embodiment, the V-shaped spring member includes opposing slots on opposite sides of the node point, the slots extending in an axial direction, creating an integrated torsion bar node spring, while reducing stress in the vicinity of the nodal point. In another embodiment, a nodal assembly comprises a diamond shaped or round insert having an upper surface configured generally to fit flush with the lower surface of the V-shaped spring member, a V-block shaped or flat shim member which is configured to mate the upper surface of the V-shaped spring member and the node spring, and an attachment member, such as a screw and nut combination, which tightly connects the mounting plate, the shim, the V-shaped spring member and the insert. | 03-25-2010 |
