Publication number: 20230180924Abstract: An oral care system includes an oral care implement and motion tracking attachment configured to allow tracking of the implement during an oral care activity such as tooth brushing. The oral care implement may include a handle and head. The tracking attachment is coupled to the implement and comprises colored tracking markers detectable by a programmable visual-based motion tracking unit. The tracking attachment in one configuration may comprise a housing with plural insertable tracking colored wedges. In another configuration, a colored tracking portion colored panels and optional colored neck band may be formed on or attached to the oral care implement. Both the tracking attachment and tracking portion embodiments as applicable facilitate tracking at least one of a position, orientation, movement, and the like of the oral care implement to which it is attached. The tracking attachment may be non-electric in nature without any onboard electronics in some embodiments.Type: ApplicationFiled: December 5, 2022Publication date: June 15, 2023Applicant: Colgate-Palmolive CompanyInventors: Takahide OKAI, Vincent EL KOUBY-BENICHOU, Olivier GIROUD, Yanmei JI, Fan Gang XIE

Publication number: 20230149140Abstract: An oral care refill head (300), the oral care refill head (300) may be detachably coupled to a handle (200). The handle (200) may include a stem (250) that is received within a connection cavity (326) of the oral care refill head (300). The stem (250) and the connection cavity (326) may have specific geometries and structures to ensure an adequate coupling therebetween. An oral care implement (100), the oral care implement (100) have a pressure sensing assembly, excessive pressure applied onto the oral care refill head (300) will cause the motor (140) and a motor chassis (401) to rock. As the motor chassis (401) rocks, a contact element (456) thereon will actuate a pressure actuator element (455). In response, a control unit (150) may initiate generation of a user perceptible signal to inform the user of the excess pressure.Type: ApplicationFiled: April 30, 2020Publication date: May 18, 2023Applicant: Colgate-Palmolive CompanyInventors: Jiang ZHOU, Yanmei JI, Wen Jin XI
