Abstract: An apparatus and method for controlling an oscillating device is presented. In particular, a controller for adjusting the frequency of a drive signal driving a haptic actuator is presented. The controller contains a calculator adapted to receive a first and a second measurement of the electrical parameter and to calculate a difference between the first measurement and the second measurement. The first measurement is obtained at a first sampling time and the second measurement is obtained at a second sampling time. The controller is adapted to provide a control signal to adjust a frequency of the drive signal based on the difference.

Abstract: A haptic system with a haptic actuator and a voltage sensor coupled to the haptic actuator, to sense a voltage across the haptic actuator. The voltage across the haptic actuator has a back electromotive force component. There is a current regulator coupled to the haptic actuator and to the voltage sensor. The current regulator is adapted to provide a current signal to drive the haptic actuator and to adjust the current signal based on the back electromotive force component. For example, the voltage across the haptic actuator may be a direct voltage or a representation of the voltage such as a filtered value of the voltage.

Abstract: A vibrating oral care device for cleaning interdental spaces includes a housing which can be gripped by human fingers. A battery is located within the housing. An electric vibrator is also located within the housing. A switch on the housing is used to electrically connect the battery to the vibrator. A rigid element extends from one end of the housing. When the switch is operated to connect the battery to the vibrator, the vibrator vibrates and causes the rigid element to vibrate.

Abstract: Oral care treatments are provided, including multi-component oral care compositions and methods for delivering such compositions to the oral cavity. Oral care devices and systems for implementing such oral care treatments are also provided.

Abstract: Tooth whitening compositions, tooth whitening films, and methods of whitening teeth are described. The tooth whitening compositions and tooth whitening films include a tooth whitening agent and a cellulose polymer of formula (I) wherein; R is H, C1-6 alkyl, (C1-6 alkylO)mR2, or —C(O)R1, wherein at least one R is H, one R is C1-6 alkyl or (C1-6 alkylO)mR2, and one R is —C(O)R1; R1 is C5-10 aryl or C1-6 alkyl, optionally substituted with at least one CO2H; R2 is H or C(O)R1; m is 1-5; and n is 2-350. The tooth whitening compositions are may be, for example, liquids or films that are applied to a tooth for a time sufficient to whiten the tooth.

Abstract: Oral care compositions are described herein. The oral care compositions generally have Theological properties that are desirable for use in a dispensing toothbrush. In some instances, the oral care composition has a yield point of y Pa and a shear slope of x Pa/Sec, wherein the ratio of yield point to shear slope is less than y/(74?370x+470x2). In some instances, the oral care composition has a Newtonian viscosity at 400 Pa of less than 1.0 Pa.s.
