Abstract: A printing apparatus which appropriately deals with a medium jam occurring on the transportation belt is provided.

Abstract: A teeth cleaning assembly includes a housing. A first wheel and a second wheel are each rotatably mounted to the housing. A belt is continuous and is positioned on the first and second wheels. The belt rotates the second wheel when the first wheel is rotated. A plurality of bristles is attached to the belt and extends away from the first and second wheels such that the bristles extend outwardly of the housing. A handle is attached to the housing and a motor is mounted within the handle. The motor is in mechanical communication with the first wheel. The motor rotates the first wheel when the motor is energized.

Abstract: In an embodiment of the disclosed technology, a toothbrush head formed of a bristled tread is rotatable about at least one vertically disposed sprocket. The toothbrush head has an elongated neck with sprockets extending axially therefrom. Bristles are wrapped around either or both sprockets. The bristles may be on a single belt wrapped around both sprockets. Alternatively, the bristles may extend from two spindles, each fitted around a sprocket. The sprockets rotate circumferentially within an upper head portion of the device. The bristles spin 360 degrees (full rotation) around the sprockets and within the stationary head. The head portion itself is replaceable or changeable, such that a handle portion may be used by multiple users or replaced.

Abstract: The self-contained intraoral appliance includes first and second substantially rigid bands (12, 14) configured to fit along the outer and the inner surfaces of a row of teeth in the mouth. A motor (20) driven by a battery is connected to the bands through a connecting assembly (2, 24, 28, 34, 40 and 44) in such a manner that one end of the first band moves through a displacement to brush the teeth while the other end remains substantially stationary, and such that an opposing end of the second band moves through a displacement while the other end remains substantially stationary. Brush elements (16, 18) are mounted on the surfaces of the bands to provide cleansing of the teeth.

Abstract: A dedusting device and method is disclosed for the dry or moist dedusting (i.e., cleaning, dusting, or removal of dirt, dust, or other debris) from components, e.g., of motor vehicles. An exemplary method may generally include positioning a dusting tool driven by a drive motor in a predetermined dusting position such that the tool contacts or touches the component, and determining a first operating variable of the drive motor of the dusting tool when positioning the dusting tool in the predetermined dusting position. The first operating variable may reflect a mechanical load of the drive motor due to the contact with the component to be dusted. The method may further include calculating a corrected dusting position as a function of the predetermined dusting position and the first operating variable of the drive motor, and positioning the dusting tool in the corrected dusting position.

Abstract: A whole mouth toothbrush with an elongate hollow handle portion, and attached U shaped brush retaining portion. The housing holds an electric motor, a battery power supply, a microprocessor, a printed circuit board and an on-off switch. A primary drive belt connects the motor shaft to a first brush spindle. A plurality of secondary drive belts connect the first brush spindle to the remaining brush spindles. Each spindle terminates in a rotating brush head. Upper brush heads brush the user's top teeth and the lower spindles brush the user's bottom teeth. The microprocessor is programmed to cause the brush retaining shafts to cycle back and forth from a clockwise rotation to a counter clockwise rotation.

Abstract: A rotating hair brush with a fins or similar implement projected into the moving path of the brush bristles. The fins automatically remove the hair/fur from the brush bristles. The amount of exposed bristles can be varied and completely concealed inside of the housing. The brush core can contain the batteries and/or motor to reduce the overall size of the assembly. A suction device can be attached to remove dislodged debris. The overall structure contains all of the components such as the motor, power source, brush and hair removal fins in a single housing. The brush is removable and can be exchanged for another with a different bristle configuration.

Abstract: A hairbrush and method of brushing are provided in which tangled hair may be brushed out at a better rate and with less pain. The hairbrush includes bristles that are mounted on revolving track portions so that when the bristles encounter a tangle or a resistance in the hair, the bristles are free to rotate. The hairbrush further includes a thumb button to adjust the resistance of the revolving track portion from a freely rotating position to a fixed position.

Abstract: A powered toothbrush includes a handle having a neck. A head is mounted to the neck and has a first portion and a second portion. A plurality of tuft blocks is mounted to the second portion, with each tuft block having a tooth cleaning element. At least one projection is positioned on one of the first and second portions, each projection engaging one of the tuft blocks and pivoting the tuft block with respect to the second portion. A drive assembly is operably connected to one of the first and second portions to drive the one of the first and second portions in an oscillating manner.

Abstract: A game ticket scratching device and method includes an elongated tubular member that has an open first end and a closed second end. An axle is mounted within the tubular member adjacent to the first end. A plurality of bristles is attached to and radially extends outwardly away from the axle. A motor is mounted within the housing and is mechanically coupled to the axle. A power supply electrically coupled to the motor. An actuator is operationally coupled to the power supply for selectively turning the power supply on or off. The power supply is turned on so that the axle rotates. The bristles are abutted against a lottery ticket concealing layer so that the bristles scrape the concealing layer off of the game card.

Abstract: Bristles for brushing a user's hair extend outwardly from a closed loop conveyor. The loop is multi-sided (preferably three sides defining a triangular or egg-shaped configuration) and has curved apices at the extremities of adjacent pairs of sides. The curved apices define different angles. The conveyor brushes the user's hair at the position of an apex with a large curvature angle when the user's hair is relatively long, the conveyor brushes the user's hair at the position of an apex with a small curvature angle when the user's hair is relatively short. The conveyor has relatively straight sides between the apices. The conveyor smoothes the user's hair when the straight sides are applied to the user's hair. The triangular configuration may be isosceles. However, the triangular configuration may have different curvature angles at the different apices. A stationary handle attached to the conveyor 58 houses a motor for driving the conveyor.

Abstract: A multifunction apparatus for engaging a surface is particularly suited for removal of snow and ice from the windshields and hoods of vehicles. The apparatus includes a support frame having two pulleys and a handle for manipulating the apparatus. An endless belt is entrained on the pulleys for movement along a continuous path. A bi-directional electrical motor is mounted on the frame and has forward and reverse modes for driving the endless belt along the continuous path. A plurality of surface engaging device assemblies having a first end connected to the endless belt and a second end extending outward from the endless belt provide for the multifunction operational modes. More specifically, each surface engaging device assembly includes first and second heads such as a scraper for removing ice and a brush for removing snow.
