20100132798 | CONTROL VALVE ACTUATION - A hydraulic system includes a power source, a fluid displacement assembly, a plurality of actuators, a plurality of control valves and an electronic control unit. The fluid displacement assembly is coupled to the power source. The plurality of actuators is in selective fluid communication with the fluid displacement assembly. The plurality of control valves is adapted to provide selective fluid communication between the fluid displacement assembly and the plurality of actuators. The electronic control unit is adapted to actuate the plurality of control valves, the electronic control unit receives a rotational speed of the power source, determines a firing frequency of the power source based on the rotational speed, selects a frequency of the pulse width modulation signal for the plurality of control valves based on the firing frequency of the power source, and actuates the plurality of control valves in accordance with the frequency of the pulse width modulation signal. | 06-03-2010 |

20090174935 | SCANNING MICROSCOPE HAVING COMPLEMENTARY, SERIAL SCANNERS - Described is a scanning microscope that includes at least two scanners disposed in series within an excitation beam, wherein one of the scanners is a two-axis galvanometer-controlled scanner, and the other of the scanners is a single-axis resonant scanner. The device may also include a spatial detection system disposed within the excitation beam at a point downstream of the at least two scanners, wherein the spatial detection system is configured to detect a sum of deflections generated by the at least two scanners, or to detect angular differences in the excitation beam when two or more illumination sources are used. | 07-09-2009 |
20130050792 | Z-AXIS OPTICAL FOCUSING MECHANISM - A Z-axis focusing mechanism having a scanner and a prism whose front and rear faces are not normal to the direction of travel of a light beam prior to the light beam impinging upon the front face of the scanner. The scanner and the prism are oriented with respect to one another such that when a light beam is scanned onto the front face of the prism, a scanned beam having varying Z-axis focus points at distinct lateral locations exits the rear face of the scanner. Alternatively, the rear face of the prism may be normal to the light beam as it passes through the prism, which generates a retro-reflected, scanned light beam that exits the front of the prism | 02-28-2013 |
