20100102672System and Method of Driving Ultrasonic Transducers - A transducer is optimally driven at or near its resonant frequency by a driver system that adapts to variations and/or changes to the resonant frequency of the transducer due to variations in piezo materials, manufacturing, assembly, component tolerances, and/or operational conditions. The system may include an output controller, a phase track controller, a frequency generator, a drive, circuitry to determine a phase angle between the transducer voltage and transducer current, and circuitry to obtain transducer admittance from the transducer voltage and transducer current.04-29-2010
20100228089Endoscopic Light Source - A light source assembly includes multiple light emitters having output that are focused and mixed onto a optical fiber leading to an endoscope or other device. The emitters can be LEDs or solid state lasers that emit different colors. A driver circuit controls the relative output intensities of the light emitters so as to produce a desired light spectrum. A driver circuit includes a buck topology connected to a controller that provides current mode control. Pulse width modulation of the buck current is provided by a semiconductor switch across a solid state laser. A second order filter, formed by the an external inductor and the output capacitance of the buck topology, minimizes AC current ripple to the laser.09-09-2010
20100241116Method and system for adjusting source impedance and maximizing output by RF generator - An electrosurgical system includes an electrosurgical probe connected to a control console, wherein the probe is capable of coagulating and ablating tissue depending on a selected operating mode. Before operating the system, probe-specific data stored in a memory device associated with the probe is read by a processing device in the console. The data includes source impedance values specific to a coagulation or cutting mode of operation. A constant duty cycle value for a modulated cutting mode also is provided. Depending on the operating mode selected, an RF generator adjusted to have a predetermined source impedance value provides a voltage value to the probe. During the duty-cycled mode, the RF generator generates an instantaneous voltage value output for a duty cycle portion that is less than 100% of a time period, which value is no less than a maximum continuous average voltage value for the electrosurgical probe.09-23-2010
