20110005328 | BI-AXIAL ELECTROMAGNETIC ACTUATOR - A biaxial electromagnetic actuator for a materials testing apparatus comprises a first electromagnetic actuator for imparting a linear force to an output shaft and a second, direct drive electromagnetic actuator for imparting a rotational force to the shaft. The shaft is mounted in two combination bearings which permit the shaft to move axially and rotationally. One of the bearings is located within a hollow cylindrical member which constitutes the armature of the direct drive actuator in order to provide a compact and symmetrical arrangement. | 01-13-2011 |
20110288791 | APPARATUS, CONTROLLER AND METHOD FOR ADAPTIVE CONTROL OF AN ELECTROMAGNETIC ACTUATOR - Provided are a structure testing apparatus, a controller for such an apparatus and a method for controlling a structure testing apparatus in which operation of a direct drive electromagnetic actuator is continuously auto-tuned during a test, so that the test load applied to a specimen during the test is the correct, desired load according to the current specimen parameters including stiffness. Forward and feedback control gains are repeatedly recalculated during the test in response to monitored specimen parameters. | 11-24-2011 |

20140331780 | MATERIAL TESTING APPARATUS AND METHOD - A method of operating a material testing apparatus comprises conducting a test by applying a fluctuating load to a material specimen at a variable test frequency, measuring the temperature of the specimen during application of the load, and varying the test frequency on the basis of the measured temperature whereby to prevent the specimen from exceeding a predetermined maximum temperature during the test. A corresponding material testing apparatus is also provided. | 11-13-2014 |

20120317856 | Caliber Conversion for Pistol - A robust and convenient caliber conversion kit is described, for example, for the higher-caliber GLOCKĀ® semi-automatic pistol. The caliber conversion kit has an internalized spent round extractor for more reliability. In addition, the firing pin safety relies on a set of two-dimensional surfaces, rather than on a one-dimensional line or edge, for cooperation (interaction and support) with the firing pin and with a recess in the firing pin housing that receives the safety, resulting in more security. Also, the spent round ejector is snugly fastened around an outwardly-extending abutment of steel on the barrel, the abutment being within a recess also snugly fitting the perimeter of the front end of the ejector, resulting in a quieter ejector mechanism. | 12-20-2012 |

20110011380 | METHOD FOR FUNCTIONAL DIAGNOSIS OF A SEPARATOR - A method for functional diagnosis of a separator for separating oil present in a blow-by has from a crankcase in a combustion engine is provided. The crankcase includes a crankcase pressure sensor, and is in fluid communication with the separator. The method includes the steps of detecting a first output signal of the crankcase pressure sensor at a first operational point or interval, and comparing the first output signal of the crankcase pressure sensor with at least one reference value or signal, wherein the comparison between said first output signal of the crankcase pressure sensor and the at least one reference value or signal provides the functional diagnosis of the separator. A method can perform a functional diagnosis without the use of additional sensors or complex algorithms and as a consequence manufacturing costs can be held at a minimum. | 01-20-2011 |

20080276938 | Method and Device For the Treating Sleep Apnea - An improved treatment of obstructive sleep apnea is disclosed. A method and various device combinations are presented. The device combinations describe optimal adjustments to properly position a nasal pillow in each of a patient's nares. A novel swivel joint is described to which a nasal pillow is slip-fit over. The swivel joint prevents loss of a proper seal between the nasal pillow and nare which may otherwise occur as a result of head movement. Also presented is an improved obturator mouthpiece design which substantially eliminates air flow through the oral cavity resulting from leakage in the oropharynx. | 11-13-2008 |
