20120123272 | ROTARY ULTRASOUND IMAGING SYSTEM - This invention relates to a rotary ultrasound imaging system comprising a control device, an ultrasound probe head and a rotary motor device, wherein the rotary motor device receives ultrasound signals sent from the ultrasound probe head, and outputs the received ultrasound signals to the control device through a 360-degree rotation; and the ultrasound probe head comprises a housing with an installation groove which is provided therein with an ultrasound transducer with a concave focusing surface. Since the concave focusing surface is directly formed on the ultrasound transducer, focusing of the rotary ultrasound imaging system is realized without addition of extra components (e.g. lens). Therefore lateral resolution and performance are improved. Furthermore, since the output shaft of the rotary motor of the rotary ultrasound imaging system is configured as a hollow shaft, ultrasound signals from the ultrasound transducer may be sent to the control device through a path of 360-degree rotation. Therefore, complicated modules are not necessary for position alignment and signal connection for 360 degrees rotary ultrasound transducer. The invention may efficiently shield disturbances arising from electrical noise. | 05-17-2012 |

The fluorogens are nonemissive in organic solution but become highly emissive when aggregated in aqueous solution. The fluorescent molecules can readily pass through cell membranes, stain only the cell cytoplasm, and form highly emissive nanoaggregates in aqueous media without any obvious cytoxicity in the living cells. Furthermore, the molecules can be retained inside the cells without noticeable leakage to the outside. Therefore, these ATE-based compounds can be used as selective and cell-compatible fluroescent bioprobes for long-term live cell tracking and imaging. | 04-11-2013 |

20080284499 | N-STAGE EXPONENTIAL CHARGE PUMPS, CHARGING STAGE THEREOF AND METHODS OF OPERATION THEREOF - An exponential charge pump uses a number of identical or similar charging stages, each having a first and second capacitor. During a first clock phase, the first capacitor of each stage is charged by the second capacitor of the preceding stage, and, during a complementary second clock phase, the positive plate of the first capacitor of each stage is pushed to an increased voltage by the first capacitor of the preceding stage and charges the second capacitor of the next stage to the increased voltage at the same time. A similar mechanism occurs to the second capacitors in each stage, but with complementary timing. The increased voltage of the first capacitor of the last stage is pumped to an output capacitor during the second clock phase, and the increased voltage of the second capacitor of the last stage is pumped to an output capacitor during the first clock phase. | 11-20-2008 |

20120073849 | VARIABLE AMPLITUDE VIBRATORY APPLIANCE - A vibratory appliance includes a tool driven to oscillate by a rotary electric motor. A shaft supported, at an intermediate portion by a pivot, is driven by an orbital drive mechanism. The orbital drive mechanism includes a rotor rotated about a rotor axis by the motor, an elongate part, and a coupler. The elongate part and the coupler are each fixed to a respective one of the inner end and the rotor. The elongate part and the coupler are mutually connected for sliding movement relative to one another, between first and second relative positions in which the inner end orbits about the rotor axis at first and second orbital radii, respectively, to vary the amplitude of oscillation of the tool. | 03-29-2012 |
20120086290 | VARIABLE AMPLITUDE VIBRATORY APPLIANCE - A vibratory appliance includes a tool driven to oscillate by a rotary electric motor.

20120099074 | Dual Lens Eyeglasses - The present invention relates to dual-lens eyeglasses including an eyeglass frame and two lens units permanently installed on the eyeglass frame. Each lens unit includes two lenses arranged in optical alignment with each other. The lenses can be optical lenses or sunglass lenses. The optical lenses can be selected from known lenses such as corrective lenses, myopic corrective lenses, reading glasses lenses, progressive lenses, etc. The sunglass lenses can be selected from polarized lenses, tinted lenses, or photochromic lenses. Without the use of sub-frames, two lens units are permanently installed on eyewires of the eyeglass frames, enhancing the integration effect of the eyeglass frames. In addition, each lens is directly fixed and installed on the eyeglass frames, so that the installation is reliable and the lenses will not fall off easily. Furthermore, the lenses can be easily installed on full-rim, half-rim or rimless eyeglass frame. | 04-26-2012 |
