  • Patent number: 10478337
    Abstract: A system for performing an ocular surgical procedure is provided. The system includes a multiple frequency signal source, a configurable tuned output filter connected to the multiple frequency signal source, and a multiple frequency ultrasonic handpiece. The multiple frequency signal source operates at a first frequency and is configured to drive the configurable filter and the multiple frequency ultrasonic handpiece at the first frequency. The multiple frequency signal source operates at a second frequency and is configured to drive the configurable filter and the multiple frequency ultrasonic handpiece at the second frequency, and the design addresses third harmonic frequency issues for the multiple frequency ultrasonic handpiece. Switchable passive components, such as inductors, resistors, and/or capacitors may be employed in the configurable tuned output circuit, or alternately multiple similar circuits may be employed. Alternately, a multi-tap transformer may be provided.

  • Patent number: 10009254
    Abstract: A method in a flow controller for selecting optimal path is provided. A plurality of potential flow paths in the network for a particular pair of source and destination switch ports is determined in a flow controller. A plurality of cost factors associated with each of the plurality of potential flow paths is identified. Individual cost values are determined for each of the identified plurality of cost factors for each of the plurality of potential flow paths by multiplying the identified cost factors by a stratification factor. A single cost value for each of the plurality of potential flow paths is determined based on the determined individual cost values. One of the potential flow paths is selected in the flow controller for the particular pair of source and destination switch ports based upon the determined single cost value.

  • Publication number: 20090299835
    Abstract: Method for advertisers to improve ad metrics through performance based prize Competitions. A business method that enables advertisers to host prize competitions that attract and motivate ad-writers to create better ads, resulting in higher click-through-rates (CTR). Advertisers challenge writers to beat the performance of their existing ads by offering cash prizes tied to the annual CPC savings their ads generate. The method automatically advertises competitions, queues submitted ads, A/B tests them, selects the ad with the highest CTR, oversees payouts (if any), and restarts the competition with the next submission. The present invention builds a base of professional writers who specialize in multiple categories of businesses. These writers are motivated by the cash prizes but also by improving their skills over multiple challenges.
