Abstract:
A wheel comprising means for providing one or more protrusions in a ground-engaging surface of the wheel. In some embodiments, the wheel comprises a first hub, a tire mounted on the first hub, a second hub rotatable with respect to the first hub, and means for deforming the tire in a generally radial direction in response to relative rotation between the first and second hubs. The invention also provides a wheel cover comprising an outer surface having one or more protrusions and, when the cover is fitted to a wheel, the outer surface of the cover provides the ground-engaging surface of the wheel. The wheel and wheel cover of the invention are particularly suited for use with prams and similar vehicles in order to impart a rocking motion to the pram during use.
Abstract:
A tactile sign (30) comprises a baseplate (31), and at least one character tile (32, 33) which is able to be securely mounted on the baseplate (31), wherein the at least one character tile (32,33) includes at least one raised tactile character (34, 35).
Abstract:
A power toothbrush (10) is disclosed having a handle (15) containing a rechargeable battery (12), an ultrasonic drive circuit (14), a sonic component (16) such as a motor, and a control unit (18). The handle is connected to a toothbrush head (20) preferably having a plurality of bristles (26) and an ultrasonic transducer (22) that is operatively connected to a waveguide (24) that extends from the toothbrush head generally adjacent the bristles. The waveguide facilitates the transmission of acoustic energy into the dental fluid. It is contemplated that the waveguide may be utilized in manual or power toothbrushes, and in a combination without the sonic component, or in a combination without the ultrasonic transducer. Toothbrushes disclosed herein achieve improved plaque and stain removal from the teeth as well as interproximal and subgingival regions, while enhancing the user experience, massaging the gums, and stimulating dental tissue.
