  • Patent number: 11234802
    Abstract: A toothbrush includes a head with a new design and a handle that operates to move the head. The toothbrush head has multiple types of purpose-designed bristle-bundles precisely mapped to target specifically all dental-gingival surfaces and anatomically niches, including various dead-corner niches/surfaces that are usually not accessible by currently existing toothbrushes. Each cluster of bristle-bundles contains bristles of different sizes, diameters, hardness, lengths, angulations and colors. The head is designed to be inclined to accommodate both lingual and palatal surfaces. This toothbrush head also functions uniquely by coupling over dental arches and rotating so that the brush does not need to be lifted during movement from one end to the other. Further, moving the handle with respect to the brush head causes the width of the brush head to change to accommodate the different widths of the teeth along the dental arch.

  • Patent number: 10978881
    Abstract: A charging device includes a charging assembly for imparting a charge on a mobile device, a housing for receiving the mobile device to be charged, and for defining a cavity therein for housing the charging assembly. There is at least one air intake port in the housing for allowing air to be drawn into the cavity and at least one air exhaust port in the housing for allowing air to be exhausted from the cavity. There is an ionic wind generator, for generating an airstream to draw air into the housing through the at least one air intake port, through the cavity, and push air out of the housing through the at least one air exhaust port. The ionic wind generator comprises an emitter and a collector, such that when a voltage is applied to the emitter, air ionizes around the emitter and is drawn toward the collector, thereby creating the airstream.

  • Patent number: 10952924
    Abstract: A lip augmentation assembly and method of selectively plumping the lips provides a housing having a first end forming a grip, and a second end. The housing encases a motor and a vibrating member. A vibrating head snugly couples to the second end of the housing. The head engages the inner surface of the lips. The head has an irregular oval shape, opposing wide sidewalls, opposing narrow sidewalls, and a concave-shaped terminus. Vibration nodules are arranged in a grid-like pattern on the wide and narrow sidewalls of the head. The vibration nodules receive vibrations from the vibrating member. An epidermal cell growth serum is topically applied to the lips before, and after, engagement with the vibration nodules. Pressing the wide sidewall of the head against the inner surface of lips, applies a deeply focused pressure on the lip. Pressing the narrow sidewall against the lips augments selected segments of lips.
