| 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 |

| 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 |
