An oral care product array includes a handle component and multiple refill components therefor. The handle component includes a power source. A first refill component includes a first light generating module which emits light in a first spectrum from the first refill component. A second refill component includes a second light generating module which emits light in a second spectrum from the second refill component. Each refill component has a coupled state, when coupled to the handle component, and a decoupled state, when decoupled from the handle component. When the first refill component is in the coupled state, the first light generating module is powered by the power source to emit light in the first spectrum. When the second refill component is in the coupled state, the second light generating module is powered by the power source to emit light in the second spectrum.

Devices, systems and methods for cleaning and disinfecting footwear items are disclosed herein. In an aspect, an apparatus is disclosed comprising an ultraviolet light element configured to emit ultraviolet light toward a top covering element configured to receive one or more contaminated item, wherein the ultraviolet light element is located within a lower frame element. In another aspect, a grating element is disclosed comprising a frame of bars configured to support the one or more contaminated item; wherein the grating element is a ceiling enclosure portion of the lower frame element. In yet another aspect, a brush frame element mounted to an underside of the grating element is disclosed, wherein the brush frame element comprises a set of brush strips configured to protrude through at least one space between the frame bars.

A hair condition-determining device can have a device body having at least one first region and one second region, wherein the first region and the second region are designed in such a way that the hair of the user can be moved between the first region and the second region, at least one optional light source arranged in or on the device body for illuminating the hair of the user, at least one optical sensor arranged in or on the device body for sensing light that has been emitted by the light source and has interacted with the hair and/or ambient light that has interacted with the hair, and an electronic circuit device arranged in or on the device body, wherein the electronic circuit device is coupled to the optical sensor in order to receive the detected light.

A diagnostic toothbrush comprising, in combination, a toothbrush body, a standard brush head containing toothbrush bristles for brushing teeth, a diagnostic brush head containing a transducer that can detect a dental pathology, and a camera brush head that can produce video images of dental and oral structures. The standard brush head, the diagnostic brush head and the camera brush head can be interchangeably mounted on the toothbrush body. Data from the diagnostic brush head is transferred to the toothbrush body when the diagnostic brush head is mounted on the toothbrush body, data from the camera brush head is transferred to the toothbrush body when the camera brush head is mounted on the toothbrush body, and the data from the diagnostic and camera brush heads is transmitted from the toothbrush body to a computing device.

End effectors and systems including end effectors including embedded batteries and auxiliary components powered by the batteries are described. In an example, the end effector includes a base portion coupleable to a motor carried by an appliance that is separate from the end effector; and a battery disposed in the base portion configured to power an auxiliary component of the end effector.

In one aspect, a system for detecting blood in an oral cavity during toothbrushing is disclosed. A toothbrush includes a sensor configured to emit first light at a first wavelength and second light at a second wavelength, and receive reflected portions of the light, the reflected portions having a first intensity and a second intensity, respectively. For each of a plurality of different times of a brushing session, a processor calculates a ratio of the first intensity to the second intensity. The processor identifies peaks in the ratio over the different times and, based on the number of peaks in the ratio, determines whether hemoglobin is present in the oral cavity.

A pet care device may include a head having a sterilizer and a handle extending from the head. The head may be formed of an outer body and an inner body positioned in an inner region of the outer body. A first space may be formed between the outer body and the inner body in which the sterilizer is provided. The sterilizer may include at least one light emitting device, and a light device may cover the first space. A second space partitioned from the first space may be at least partially located inside the inner body. Hair and/or debris may be collected in the second space.

A pet care device may include a removable or swappable care tool mounted on a head. The head may include a sterilizer and a sensor to determine what kind of care tool is mounted. A controller may identify the type of care tool mounted on the head based on a sensing value of the sensor and control the sterilizer based on the identified care tool.

The Total Kleen is a toothbrush innovated with floss dispensed through it to clean between teeth and a LED inside of it that with a tooth whitening agent can be used to brighten teeth.

An oral care system includes an oral care implement and a smart device removably retained in a cavity of the oral care implement. The smart device may have a plurality of sensors for sensing conditions of the oral cavity and/or for sensing various parameters associated with the movement of the oral care implement within the oral cavity during use. The smart device may also include a transmitter for transmitting data/information obtained by the sensors to an electronic device, such as a smart phone.
