A vehicle wash system includes a vehicle treatment area and an overhead frame portion supporting a pair of side brushes. The side brushes are configured to treat the lateral sides of the vehicle and may also treat the front and back of the vehicle. The side brushes are configured to pivot between a vertical position and an outwardly angled position, in which the side brushes are generally aligned with the side glass of the vehicle windows. The side brushes may travel along the side of the vehicle in both the vertical and pivoted orientations. The side brushes may make multiple passes along the side of the vehicle, and the side brushes may change orientation during or between passes to treat different segments of the vehicle.

A personal-care device has a rechargeable energy storage, a charging circuit for receiving energy from an external energy source and for charging the rechargeable energy storage, a first charging mode in which the rechargeable energy storage is charged to a predetermined maximum voltage value, and a user-selectable second charging mode in which the rechargeable energy storage is charged until the voltage at the rechargeable energy source has reached a first predetermined voltage value that is lower than the predetermined maximum voltage value. The present disclosure is also concerned with a system having such a personal-care device and a charger.

A method for monitoring the position of an oral care device in the mouth of a user, the method comprising emitting energy towards the user's face, receiving reflected energy from the user's face corresponding to the emitted energy, and determining the position of an oral care device in the mouth of the user using the received reflected energy and facial characteristics information of the user which relates to one or more facial features of the user.

The present invention describes a method for a U-shaped teeth brush device having a conformable shape adjusting U-shaped teethbrush module and one or more individual tooth brushes coupled to the power drive mechanism, each brush having a sensor, piezoelectric crystal and transducer and each tooth brush having a block anchor coupled to the power drive, under smart controls, an electronic control system for sensing individual tooth pressure and controlling motor transmission of vibration to prior positioned brushes, whereby a users unique mouth features can be accounted for by adjusting U-shape distal ends to fit through the users mouth and align with users teeth arch for programmatically brushing more than one tooth simultaneously.

A method and system for identifying an attachment of a personal care device (10). The method includes attaching an attachment (14) containing a memory (16) to a body portion (12) of a personal care device. The personal care device is powered up. Data is retrieved from the memory of the attachment. Information about the attachment attached to the personal care device is extracted from the retrieved data, the information including at least an association of the attachment to a specific user. An output characteristic of a status indicator (30) of the personal care device is associated with the ID (22) of the attachment. The status indicator is operated in accordance with the output characteristic when the attachment is coupled to the body portion of the personal device.

A personal care device including at least one sensor (28) configured to obtain sensor data including information about a user; a controller (30) having a feature extraction module (230) and a classifier (240), the feature extraction module configured to extract one or more features from the obtained sensor data, the classifier configured to determine a status of a user based on the extracted one or more features; and a personal care device (10) configured to provide a personal care function and receive one or more control signals to adjust the personal care function based on a determined status of at least a portion of the user's body.

A computer system receives user-specified settings for a custom formulation of a personal care product, obtains manufacturing parameters for the custom formulation based at least on part on the user-specified settings for the custom formulation; and transmits the manufacturing parameters to a manufacturing computer system. The manufacturing parameters are configured to initiate or guide a manufacturing process to produce the custom formulation of the personal care product. The computer system also receives user-specified settings for a personal care device having at least one computer-controlled component, obtains operational parameters for the personal care device based at least in part on the user-specified settings for the personal care device; and transmits the operational parameters to a remote computing device in communication with the personal care device. The operational parameters are configured to modify at least one operational characteristic of the at least one computer-controlled component of the personal care device.

A personal care device comprises at least one treatment application unit configured to apply a treatment to user; a human-machine interface (HMI) comprising a speaker; and a personal care unit operably coupled to the HMI and to the at least one treatment application unit. The personal care unit includes circuitry for presenting voice cues via the HMI in a computer-guided care routine to guide user operation of the personal care device, and circuitry for controlling the at least one treatment application unit. In an embodiment, the circuitry for presenting voice cues via the HMI includes circuitry for generating a random selection from a set of voice cues stored in memory and/or computational circuitry including one or more processors operably connected to a speaker and configured to enable one or voice cues via the HMI that sequence in concert with a computer-guided care routine stored in memory.

A vibrating toothbrush and an eccentric shaft are proposed. The vibrating toothbrush includes a head in which bristles are planted, and a handle from which a head coupler protrudes, the head being detachably coupled to the head coupler. The toothbrush includes an electric motor accommodated in the handle to generate rotating force; and an eccentric shaft rotatably connected to the electric motor, at least a portion thereof being eccentric to generate vibration and thereby transmit vibration to the head coupler. The eccentric shaft includes a motor fixing part connected to the electric motor; an eccentric weight configured to be offset from a rotation center of the electric motor; and a rotating shaft formed of a metal material, and connecting the motor fixing part and the eccentric weight.

This invention relates to a drive system which automatically disengages when a loading above a certain threshold limit is applied to the driven component, thus preventing damage to the drive system and foremost to the gearing between the drive system and the driven component when such a load is applied.
