Tooth brushing monitoring system is disclosed that includes a toothbrush with sensors and a base station. The sensors record data regarding the quality, quantity and location of brushing and the system can analyze the data to provide feedback on the quality of brushing. This feedback provides motivation for users to increase their brushing habits, leading to a decrease in plaque, tooth decay and gingivitis.

A vehicle washing system includes a frame disposed above a vehicle treatment area, and an extendable and retractable scissor mechanism coupled to the frame. A rotatable top brush is coupled to a bottom end of the scissor mechanism, and the scissor mechanism is extendable downward to lower the top brush into engagement with a vehicle body and retractable upward to remove the brush from engagement with the vehicle body. The scissor mechanism may include a brush support flange coupled to a bottom end of the scissor mechanism. An anti-spin member may extend from the support member to the scissor mechanism to prevent bending of the scissor mechanism in response to rotating to the top brush. The anti-spin member may be in the form of a fork that slidably engages a protrusion of the scissor mechanism.

A method (200) for determining a position and an orientation of a portion of a handheld personal care device relative to a user's body (50), comprising: providing (210) a handheld personal care device comprising at least one energy source (20) and at least one detector (22), both the at least one energy source and the at least one detector located within the handheld personal care device, the at least one energy source arranged at a first position and having a first orientation within the handheld personal care device; emitting (220) energy in a three dimensional space surrounding the handheld personal care device; detecting (230) a portion of the energy emitted; generating (240) sensor data; extracting (250) one or more features from the generated sensor data; and estimating (260) a position and an orientation of a portion of the handheld personal care device relative to the user's body based on the extracted one or more features.

A method (400) for modifying a user's oral care program. The method includes the steps of: (i) providing (410) a network (200) comprising a first personal care device (10a) in communication with a second personal care device (10b); (ii) cleaning (420) at least a portion of the oral cavity using the first personal care device; (iii) obtaining (440), while cleaning with the first personal care device, sensor data for the at least a portion of the oral cavity; (iv) communicating (450) the obtained sensor data to the second personal care device; and (v) modifying (460), based on the communicated sensor data, a function of the second personal care device.

A brush head assembly comprising: a hard platen; a plurality of bristle tufts, each of which comprises a plurality of bristle strands, each bristle tuft having a proximal end and a free end; and a flexible matrix at least partially comprised of a shear-thickening material for coupling the plurality of bristle tufts to the hard platen, wherein the flexible matrix is arranged such that there is shear-thickening material between the proximal ends of the plurality of bristle tufts and the hard platen. A method of manufacturing the brush head assembly for use with a personal care appliance.

An oral care system may include: an oral care device including: at least one teeth cleaning element; and at least one sensor configured to detect motion of the oral care device during a brushing routine of a user and to generate sensor data corresponding to the detected motion; and a programmable processor configured to: receive the sensor data generated by the at least one sensor; and determine a target brushing time based on the sensor data.

A comb with a laser function includes a main body, a laser irradiation portion, a vibration portion and a controlling portion. The laser irradiation portion, the vibration portion and the controlling portion are disposed on the main body. The controlling portion is connected to the laser irradiation portion and the vibration portion. The main body includes a brush portion and a handle portion. The brush portion includes a comb tooth portion, and the comb tooth portion includes multiple comb teeth. The laser irradiation portion is adjacent to the comb tooth portion and irradiates a laser beam to a scalp according to the control of the controlling portion. The vibration portion is disposed on the brush portion to generate a vibration according to the control of the controlling portion. The comb with the laser function is capable of irradiating the laser beam to the scalp and massaging the scalp.

A substrate treatment apparatus includes a brush moving mechanism which moves a shaft to which a cleaning brush is attached. The brush body includes a substrate contact portion of a pillar-shaped portion. The substrate treatment apparatus further includes a correcting member and a relatively-positioning mechanism. When the correcting member is placed in a target position, a contact portion of the correcting member overlaps an object portion which is a combination of a design contact portion and a belt-shaped annular portion in an outer surface of a design pillar-shaped portion of a design body of a design brush. The contact portion is formed to have an inverted shape of the object portion of the design brush, and a portion of the contact portion, which corresponds to the belt-shaped annular portion, is a center-axis facing surface which faces a center axis of the shaft.

The amplitude control assembly for an oral care appliance includes a capacitance-sensing touch array (26) responsive to the position of a user's touch thereon to change the value of capacitance from the array, as determined by a sensor (30). A control assembly (24), responsive to the change of capacitance, changes an operating characteristic of the drive signal for the appliance, to change the amplitude of motion of a workpiece portion of the oral care appliance.

The present invention discloses an electric pet hair brush. The electric pet hair brush. comprises a shell, a roller, a control module and a power module. The shell has an accommodation space. The control module and the power module are electrically connected and are accommodated in the accommodation space. The roller is arranged at the front end of the shelf and is connected with the power module. The roller can be driven by the power module to rotate. The roller comprises a roller main body and multiple comb assemblies. The power module drives the roller main body to rotate, and the multiple comb assemblies can alternatively and circularly extend from the roller main body or retract into an accommodation space of the roller main body with the rotation of the roller main body.
