20080223119 | Fast-Scanning SPM Scanner and Method of Operating Same - A high-bandwidth SPM tip scanner is provided that additionally includes an objective that is vertically movable within the scan head to increase the depth of focus for the sensing light beam. Movable optics also are preferably provided to permit targeting of the sensing light beam on the SPM's probe and to permit the sensing light beam to track the probe during scanning. The targeting and tracking permit the impingement of a small sensing light beam spot on the probe under direct visual inspection of focused illumination beam of an optical microscope integrated into the SPM and, as a result, permits the use of a relatively small cantilever with a commensurately small resonant frequency. A high-bandwidth tip scanner constructed in this fashion has a fundamental resonant frequency greater than greater than 500 Hz and a sensing light beam spot minor diameter of less than 10 μm. Images can be scanned on large samples having a largest dimension exceeding 7 mm with a resolution of less than 1 Angstrom and while scanning at rates exceeding 30 Hz. | 09-18-2008 |
20090032706 | Fast-Scanning SPM and Method of Operating Same - A method and apparatus are provided that have the capability of rapidly scanning a large sample of arbitrary characteristics under force control feedback so has to obtain a high resolution image. The method includes generating relative scanning movement between a probe of the SPM and a sample to scan the probe through a scan range of at least 4 microns at a rate of at least 30 lines/sec and controlling probe-sample interaction with a force control slew rate of at least 1 mm/sec. A preferred SPM capable of achieving these results has a force controller having a force control bandwidth of at least closed loop bandwidth of at least 10 kHz. | 02-05-2009 |

20130102968 | Intravenous catheter securement device - An intravenous catheter securement device to secure an IV cannula, IV tubing, and attachments in place and to reduce the need for adhesive tape application, including a protective dressing body that secures an intravenous catheter between a cover flap and a lower portion thereof; a continuous pocket disposed between cover flap and the lower portion inner sides for securing a splint for immobilizing an IV site with minimal interference of the dressing body; an opening centrally disposed on the lower portion that serves as a viewing port over an IV site; a vertical slit centrally disposed on the lower portion between the front side and the opening that permits the dressing body to pass either side of a cannula and IV tube; and various attachment strips and tabs that secure an IV line to prevent kinking thereof and to prevent the IV line from weighing down on the cannula. | 04-25-2013 |

20150330282 | TURBOGENERATOR SYSTEM AND METHOD - A turbogenerator system for extracting energy from a fluid stream is described. The system comprises a turbogenerator arranged to be driven by the fluid, the turbogenerator comprising a turbogenerator turbine having an inlet for receiving the fluid and an outlet for exhausting the fluid. The turbogenerator further comprises an alternator arranged on an output shaft of the turbogenerator turbine for the conversion of shaft power into electrical power. A control arrangement is provided for controlling operation of the turbogenerator in dependence upon operating conditions for the turbogenerator system. | 11-19-2015 |
