According to an aspect there is provided a motor () for a personal care device (). The motor () comprises: a stator () comprising a stator surface; a rotor () comprising a rotor surface disposed opposite the stator surface; and a spacer () projecting between the stator surface and the rotor surface so as to define a minimum airgap between the stator () and the rotor (). The spacer () is disposed on or at one of the rotor surface and the stator surface, and has a contact surface configured to engage with the other one of the rotor surface and the stator surface.

Motor for a personal care device

According to an aspect there is provided a drivetrain assembly () for a personal care device (). The drivetrain assembly () comprising: a shaft (); a frame () comprising an opening in a surface () of the frame () through which the shaft () extends; and an abutment () provided in cooperation with the shaft (). An engagement surface () of the abutment () is configured to engage with the surface () of the frame () such that relative movement between the frame () and the shaft () in a given direction (d) is inhibited past a threshold distance.

Drivetrain assembly for a personal care device

An oral cleaning device () for characterizing a position of a brush head of the device. The oral cleaning device includes: a body portion (); a brush head () extending from the body portion, where at least a portion of the brush head is configured to move relative to the body portion; a controller (); and an optical sensor () positioned relative to the brush head member and body portion and being in communication with the controller, where the optical sensor is configured to obtain optical sensor data resulting from a deflection or rotation of the brush head member relative to the body portion; the controller being configured to receive the optical sensor data and determine the deflection or rotation of the brush head member relative to the body portion.

Methods and systems for optical sensing of forces in a toothbrush

A drivetrain assembly () for a personal care device (), the drivetrain assembly including a primary resonator (); a secondary resonator () configured to reduce vibrations transmitted from the motor to a body () of the personal care device; a fixed point () positioned between the primary resonator and the secondary resonator; a first spring member () connected at a first end to the primary resonator and at a second end to the fixed point; a second spring member () connected at a first end to the secondary resonator and at a second end to the fixed point; a coupling spring () connected at a first end to the primary resonator and at a second end to the secondary resonator; and an actuator () configured to exert force on at least one of the primary resonator and the secondary resonator.

A temperature conditioning system for a lithographic apparatus. Temperature variations in an object cause object deformation which prevents the object being accurately positioned. Temperature condition systems use conduit systems, provided with fluid, in or on the object to control the temperature of the object to reduce object deformation. In this way, parts of the object can be more accurately positioned. However, acceleration of the object and the temperature conditioning system induces variation in pressure within the fluid inside the conduit system on or in the object, which may also cause object deformation. To provide an improved conduit system, the lithographic apparatus further includes a control system which is used to control the movement of the object based on measurements indicating pressure variation in the conduit.

Lithographic apparatus, object positioning system and device manufacturing method

A lithographic apparatus includes: an object that is moveable in at least one direction; a control system to move the object in the at least one direction, wherein the control system is arranged to control movement of the object in the at least one direction in a frequency range of interest; and a conduit provided with a fluid, wherein the conduit is arranged on or in the object in a pattern, and wherein the pattern is such that an acceleration of the object in the at least one direction causes an acceleration pressure profile in the fluid along the conduit, the acceleration pressure profile not matching with a resonance pressure profile that corresponds to a standing wave mode in the fluid with a resonance frequency in the frequency range of interest.
