Resonant converter tuning for maintaining substantially constant phaco handpiece power under increased load

ActiveUS6997935B2Simple filterReduced transistor switching loss lossEye surgerySurgeryPhacoemulsificationTransducer
A phacoemulsification system includes a phacoemulsification handpiece including a cutting tip ultrasonically vibrated by an ultrasonic transducer. A power supply is provided for driving the ultrasonic transducer at a resonant frequency of the transducer and cutting tip and varying power to the transducer, in response to loading of the cutting tip, by phase shifting drive signals to the resonant converter which supplies power to the transducer.

Actively controlled rotary steerable system and method for drilling wells

An actively controlled rotary steerable drilling system for directional drilling of wells having a tool collar rotated by a drill string during well drilling. A bit shaft has an upper portion within the tool collar and a lower end extending from the collar and supporting a drill bit. The bit shaft is omni-directionally pivotally supported intermediate its upper and lower ends by a universal joint within the collar and is rotatably driven by the collar. To achieve controlled steering of the rotating drill bit, orientation of the bit shaft relative to the tool collar is sensed and the bit shaft is maintained geostationary and selectively axially inclined relative to the tool collar during drill string rotation by rotating it about the universal joint by an offsetting mandrel that is rotated counter to collar rotation and at the same frequency of rotation. An electric motor provides rotation to the offsetting mandrel with respect to the tool collar and is servo-controlled by signal input from position sensing elements such as magnetometers, gyroscopic sensors, and accelerometers which provide real time position signals to the motor control. In addition, when necessary, a brake is used to maintain the offsetting mandrel and the bit shaft axis geostationary. Alternatively, a turbine is connected to the offsetting mandrel to provide rotation to the offsetting mandrel with respect to the tool collar and a brake is used to servo-control the turbine by signal input from position sensors.

Phosphor screen and displays systems

A phosphor screen for image forming including phosphor material being excitable by light in a wavelength λ1. The phosphor screen receives an optical image from an image forming optical system and produces the optical image at a second wavelength λ2. The phosphor screen includes a phosphor layer comprising the phosphor material. A short-pass reflective coating is positioned on a first side of the phosphor layer. The short-pass reflective coating transmits the wavelength λ1 and reflects the wavelength λ2. A long-pass reflective coating is positioned on a second side of the phosphor layer. The long-pass reflective coating transmits the wavelength λ2 and reflects the wavelength λ1. A first substrate is positioned over the short-pass reflective coating. The first substrate is formed of optically clear and thermal conductive material. A second substrate is positioned over the long-pass reflective coating. The second substrate is formed of long-pass absorptive optical filter material that transmits the wavelength λ2 and absorbs wavelength λ1 from ambient light to prevent the phosphor layer from being excited by the ambient light. The phosphor screen may alternatively be used for a direct-view visual display apparatus. These principles can also be utilized for backlighting and general illumination applications.

Apparatus and method for communication

A communication apparatus and a communication method realizing highly amusing features and merchantability. A face image of the sender of a text message changes according to the contents of the message, especially symbols, marks and the like which indicate an emotional state in the message. Thereby, an image suitable for each symbol, mark or the like which indicates an emotional state in the text message is selectively displayed on a screen. Thus, the user of a communication apparatus can immediately understand sender's feeling without reading all the text message.

System and method for predicting consumer credit risk using income risk based credit score

InactiveUS20110078073A1Accurate assessmentImprove acquisitionFinanceIncome lossProspective evaluation
Systems and methods are described for scoring consumers' credit risk by determining consumers' income risk and future ability to pay. Methods are provided for measuring consumers' income risk by analyzing consumers' income loss risk, income reduction risk, probability of continuance of income, and economy's impact on consumers' income. In one embodiment, a method is provided to evaluate an individual's creditworthiness using income risk based credit score thereby providing creditors, lenders, marketers, and companies with deeper, new insights into consumer's credit risk and repayment potential. By predicting consumers' income risk and the associated creditworthiness the present invention increases the accuracy and reliability of consumers' credit risk assessments, results in more predictive and precise consumer credit scoring, and offers a new method of rendering a forward-looking appraisal of an individual's ability to repay a debt or the ability to pay for products and services.
