  • Publication number: 20240196120
    Abstract: A loudspeaker system can have first and second loudspeakers selectively operable in a single-channel mode or in a multi-channel mode. In the single-channel mode, the first and the second loudspeakers are configured to simultaneously reproduce a substantially identical signal. In the multi-channel mode, the first loudspeaker reproduces a first-channel signal and the second loudspeaker reproduces a second-channel signal. The first-channel signal and the second-channel signal can constitute respective portions of a multi-channel signal. Such loudspeaker systems can also have a mode selector configured to select one of the single-channel mode and the multi-channel mode. In some embodiments, such selection can occur in response to one or more detected proximities of another loudspeaker system. Multi-zone loudspeaker systems are also disclosed.

  • Patent number: 10441764
    Abstract: The applicator includes a housing and a motor contained therewithin which includes an output member, such as a shaft, which in operation moves in a reciprocating manner. A contact member is mounted for operation and moves in response to the action of the output shaft, such that the contact element in operation repeatedly contacts a selected skin area, moving toward and away from the skin area, substantially perpendicularly thereto. The contact member moves at a frequency within the range of 50 Hz to 200 Hz and with an amplitude of 0.010 to 0.075 inches. The repeated tapping action of the contact member against the skin increases the absorption of a skin formulation into the skin area being contacted.

  • Patent number: 8740917
    Abstract: The apparatus includes at least two skin-contacting elements, the elements having narrow end faces and a mounting assembly for holding the elements closely adjacent to each other. A driving assembly reciprocally moves one element relative to the adjacent element(s) at a frequency that produces an action on the pores of the skin to loosen sebaceous plugs present in the pores, by permitting their ready removal from the skin.

  • Patent number: 7267673
    Abstract: The acne treatment devices use an array of LEDs, which emit monochromatic light substantially at a wavelength of 405 nanometers, which is coincident with the peak absorbance of light by acne porphyrins. The emitted light is directed from the light source to an acne area of the skin. The device can either be hand-held, with the LEDs mounted on a handle portion, or an LED can be mounted on a patch-like mounting element, which is adapted to be secured to the skin for longer exposure at less intensity.

  • Patent number: 7157816
    Abstract: The motor assembly which produces an oscillating action for a personal care device includes a horizontally positioned U-shaped stator portion, and an armature portion which includes a torsion spring shaft which is anchored at one end thereof. The armature portion also includes a U-shaped magnet mounting member which is fixed near the upper end of the spring shaft, the U-shaped member including two opposing legs which extend along a substantial part of the length of the spring shaft, away therefrom. At the tips of each leg are magnet assemblies, which interact with the stator portion in alternating torsion, to produce a back-and-forth oscillation of the armature and a brushhead or other workpiece attached thereto.

  • Patent number: 5815872
    Abstract: A power toothbrush has a brushhead mounted at one end thereof, the brushhead including a base mounting element for bristles which extend from one surface thereof. Extending from the opposing surface of the base mounting element is a pressure contact member. A substantially rigid brushhead shield extends along and is adjacent to the opposing surface of the brushhead. The brushhead has a hinge-like portion which permits the brushhead to move or swivel in response to pressure being placed on the brushhead, while the brushhead is moving back and forth at its operating frequency of its normal brushing action at over 150 Hz. Thin electrical switch contacts, which are part of an electrical circuit, are positioned on the brush shield, spaced from the contact member on the brushhead.

  • Patent number: 5784742
    Abstract: An electric toothbrush (10) with an adaptive load sensor (12) is disclosed. The toothbrush of this invention includes a brushhead (16) that is vibrated by a drive assembly (18). The load sensor monitors the current drawn by the drive assembly to determine the mechanical load to which the toothbrush is exposed. The load sensor assembly produces an adaptive threshold signal that represents the instantaneous maximum pressure load. If the sensed load voltage exceeds the adaptive threshold signal, the load sensor assembly deenergizes the drive assembly and generates an alarm signal so as to give the user a warning that the toothbrush has been excessively loaded.

  • Patent number: 5544382
    Abstract: A vibrating toothbrush, which includes a handle member, an elongated arm which has a brushhead at the distal end thereof, and a drive assembly for moving the brushhead at a selected velocity. Responsive to an on/off switch on the toothbrush is an on/off variable, which enables a master clock to produce a drive signal, the on/off variable being reset by a 120-second timer. A quadtimer variable, when in the enabled state, is responsive to the on/off switch to produce an audible signal and a difference in brush velocity at 30-second intervals within the 120-second period.

  • Patent number: 5476384
    Abstract: A vibrating toothbrush which includes a brushhead (18) mounted for vibrating movement, a reservoir (30) for containing dentifrice which is located in the handle (14) of the toothbrush, and fluid connecting means (32) connecting the reservoir (30) to the brushhead (18). The brushhead (18) includes either hollow bristles (80) or nozzles (87) in the brushhead (18) to permit egress of the dentifrice from the brushhead (18) in the area of the bristles. The brushhead (18) is driven so as to provide a scrubbing action for the teeth and to provide acoustical energy for acoustical cleansing as well. The action of the brushhead (18) and the load thereon will result in dentifrice being released out of the brushhead (18) or bristles (80) as needed, supporting cavitation and streaming for the acoustical energy, as well as providing the cleansing/therapeutic effect of the dentifrice.

  • Patent number: 5378153
    Abstract: The dental hygiene apparatus includes a body portion (12) from one end of which extends a elongated resonator arm (32). The arm (32) is mounted for oscillating action about a torsion pin (38), by means of a electromagnet (16) in the body acting in combination with two permqanent magnets (34, 35) which are mounted on the rear end (31) of the resonator arm (32). On the forward end (44) of the resonator arm (32) is mounted a set of bristles (47). The arm (32) is driven such that the tips of the bristles operate within ranges of amplitude and frequency to produce a bristle tip velocity greater than 1.5 meters per second, producing a significant cleansing effect beyond the tips of the bristles.
