摘要： A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from a relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.

摘要： Oral hygiene devices employing an ultrasound transducer are disclosed. The device is user-activatable to commence an operating cycle, and has a controller that may provide a timing function and may provide a variable level of ultrasound transducer output during an operating cycle. The controller may provide a monitoring function that is capable of detecting an ultrasound transducer fault condition and alert a user, through a user interface, when an ultrasound transducer fault condition is detected. The controller may be programmed to count the number of device operating cycles or accumulate the total device operating time and activate a transducer replacement signal following a predetermined number of uses or a predetermined accumulated operating time. The ultrasound transducer assembly may be provided in operative communication with an ultrasound drive circuit and power supply by means of a transformer assembly that inductively couples and transfers power from the ultrasound drive circuit to the ultrasound transducer.

摘要： Disclosed are methods and related compositions for altering the physical and chemical properties of a substrate used in hydrocarbon exploitation, such as in downhole drilling operations. In a preferred embodiment a method involves formulating a fluid, tailored to the specific drilling conditions, that contains one or more inactivated enzymes. Preferably the enzyme is inactivated by encapsulation in a pH responsive material. After the fluid has been introduced into the well bore, one or more triggering signals, such as a change in pH, is applied to the fluid that will activate or reactivate the inactivated enzyme, preferably by causing it to be released by the encapsulation material. The reactivated enzyme is capable of selectively acting upon a substrate located downhole to bring about the desired change in the chemical or physical properties of the substrate.

摘要： A wellbore fluid including a peroxide degradable polymer and an encapsulated peroxide source. The peroxide degradable polymer may be a polysaccharide. The peroxide source may include an inorganic peroxide, including zinc and alkaline earth metal peroxides, such as magnesium peroxide. The encapsulating material may be a polymer, including enteric polymers. The release of peroxide, from peroxide sources generally, can be controlled by means of pH such that peroxide source can be activated, and peroxide released, by a change in pH. In a wellbore, this pH change can be effected by using produced fluids to lower the pH of a more basic wellbore fluid.

摘要： A method and apparatus for controlling the tension in a tape (16, 18) along a feed path between a reel (84, 112) and a processing station (20) is disclosed. A motor (146, 162) having a controllable torque is coupled to the reel. An advancement mechanism (22, 142) advances the tape through the processing station. Sensors (190, 192) produce signals proportional to the advancement of the tape through the processing station as well as the advance of the reel. These signals are compared to produce an indicia of the present operating radius of the tape on the reel, which is dependent upon the amount of tape wound upon the reel. With this indicia determined, empirically derived data can be consulted to determined the energization of the motor necessary to produce a torque that will compensate for the changing tape diameter on the reel, maintaining the tension in the tape substantially constant independent of the transfer of tape with respect to the reel. In a preferred embodiment, this arrangement is employed to control the tension in thermal transfer ribbon (16) and receiving paper (18) between a print roller (22) and their respective reels (146, 162) in a thermal transfer printer (10).
