A universal base for an electric toothbrush has a body comprising a top surface, a bottom surface, and a side surface therebetween. The base can be coupled with the toothbrush for wireless communication therebetween. The base includes a charging component for inductively charging the electric toothbrush, a Bluetooth component for communicating usage data received from the toothbrush during a brushing session, an analyzing component for instantaneous processing of the usage data received from the toothbrush, a timer-clock component for displaying either a count-up or a countdown of the brushing session during the brushing session and time of day before and after the brushing session, and a multi-functional light component for instantaneously communicating, during the brushing session, at least one element of the usage data.

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.

A toothbrush having one or more light sources with an electronic interlock control device preventing operation of the light source when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of about 400 nm to about 1000 nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head.

A system for detecting blood in an oral cavity during toothbrushing. The system may include a toothbrush having a sensor that is configured to emit first light at a first wavelength and second light at a second wavelength, receive reflected portions of the first and second light, and generate a first signal indicative of a first intensity of the reflected portion of the first light and a second signal indicative of a second intensity of the reflected portion of the second light. The system may include a processor operably coupled to the sensor, the processor being configured to receive the first and second signals and calculate a ratio of the first intensity to the second intensity to determine whether hemoglobin/blood is present in the oral cavity. The processor may be a part of the toothbrush or a part of a portable electronic device such as a smart phone.

An electric toothbrush includes a handle with a motor and a light source located in a proximal end. A brush head is in a distal end of the toothbrush, and a drive shaft conveys kinetic energy from the motor to the brush head. The drive shaft includes a light guide from the light source to the distal end and contains two layers of an optical medium of differing refractive indices to enable TIR within the light guide. The brush has a tuft plate having bristles and is made of a polymer such that the water contact angle of the tuft plate is less than 90 degrees and is at least partially transparent. The handle and the tuft plate have electrical contacts to make a contact sensor and a movement sensor provides movement data. A computing device processes movement and contact data to determine when to activate the light.

An embodiment provides a handheld implement, including: an elongated handle comprising a first end and a second end substantially opposite the first end; an implement head located at and mechanically attached to one of: the first end and the second end; and a light source mechanically coupled to and along a longitudinal axis of the elongated handle, wherein the light source is positioned at a location on the elongated handle such that a least a portion of light that emits from the light source illuminates an area proximate to the implement head. Other aspects are claimed and described.

A device comprises an interdental brush, a delivery component, and a lighting system. The interdental brush is disposed at a first end of the device and includes a working part and a connector. The delivery component includes a guide head and a sliding mechanism that is mechanically connected to the guide head. The guide head includes a bended tube within which the working part of the interdental brush is positioned. An outlet of the bended tube is disposed at an end of the guide head. The sliding mechanism includes a sliding block and an interdental brush connecting mechanism that mechanically connects the interdental brush to the sliding block. The lighting system includes a switch and a light source. The light source is disposed at the first end of the device and is electrically coupled to the switch through the guide head that houses the interdental brush.

Oral hygiene monitoring system is disclosed to track motion and orientation of an oral hygiene device. The control system may process data output from a motion sensor to determine position and orientation of an oral hygiene device with respect to a user's mouth. In some examples, the system may use machine learning techniques to identify position and orientation, brush stroke type, and other specific actions.

Disclosed is a paw cleaning device for pet animals. The paw cleaning device of the present invention is an improved device for cleaning a pet's paws by providing a light source for adequate lighting during the cleaning process. The light source provides a halo-illumination lighting effect such that a 360-degree light encircles the paw, including particular regions of the paw being cleaned. The use of halo-illumination allows a user to see specific regions of the paw being cleaned, thus providing the user sufficient information about the health of the pet.

Disclosed is a toothbrush for cleaning teeth of a pet animal. The toothbrush of the present invention is an appropriate device for cleaning a dog's teeth by providing adequate lighting via the same toothbrush during the cleaning process. The lighting provides a halo-illumination lighting effect such that a 360-degree light encircles the tooth during cleaning. The use of halo-illumination allows a user to see top, bottom, and both sides of the dog's mouth in a particular region, thus providing the user sufficient information as to whether they are effectively performing teeth cleaning of the dog.
