20140180275 | METHOD AND SYSTEM FOR CONTROLLING AN OUTPUT OF A RADIO-FREQUENCY MEDICAL GENERATOR HAVING AN IMPEDANCE BASED CONTROL ALGORITHM - A system for performing an electrosurgical procedure at a surgical site is disclosed. The system includes a sensor configured to continually sense an electrical and/or a physical property of tissue at a surgical site and to generate a sensor signal as a function thereof. The system also includes a control module configured to process the sensor signal using a processor, an algorithm, and a map having one or more predetermined values. The control module is further configured to compare the sensor signal to a predetermined level to determine reliability of the sensor signal and to signal an electrosurgical generator in response to a reliable sensor signal such that the electrosurgical generator enters energy control mode, wherein the electrosurgical generator matches an output of the control signal with a predetermined value from the map. | 06-26-2014 |

20110303515 | ELECTROSTATICALLY ACTUATED MICRO-MECHANICAL SWITCHING DEVICE - An electrostatically actuated micro-mechanical switching device with movable elements formed in the bulk of a substrate for closing and releasing at least one Ohmic contact by a horizontal movement of the movable elements in a plane of the substrate. The switching device has a drive with comb-shaped electrodes including fixed driving electrodes and movable electrodes. A movable push rod is mechanically connected with the movable electrodes, extends through the electrodes, has a movable contact element at one side, and at least one restoring spring. A signal line has two parts interrupted by a gap. The micro-mechanical switching device is in shunt-configuration with low loss, high isolation in a wide frequency range, low switching time at low actuation voltage and sufficient reliability. The line impedance of the signal line and its variation is as small as possible. The switching device is in shunt-configuration for closing and releasing the Ohmic contact between a ground line and the signal line. The contact element has a movable contact beam extending at least partially opposite to the signal line and being electrically and mechanically connected to both parts of the signal line, respectively. The ground line is formed with a contact bar that leads through the gap of the signal line for forming the Ohmic contact between the contact beam and the ground line. A contact metallization is provided at least on top and on the side walls of the contact beam, of the signal line and of the ground line. | 12-15-2011 |

20150160543 | MOBILE MICROPROJECTOR - A mobile microprojector is provided to include at least one deflectable micromirror for scanning a projection surface with the aid of a light beam, as well as a control unit for controlling the movements of the micromirror, the control unit being configured to effectuate at least one deflection of the micromirror via a first amplitude in a first operating state for scanning the projection surface. The control unit is configured to effectuate the deflection of the micromirror via a second amplitude in a second operating state, the second amplitude being smaller than the first amplitude. | 06-11-2015 |
