| 20110191085 | SYSTEM AND METHOD FOR COMMISSIONING OF A BEAM MODEL FOR A THREE DIMENSIONAL RADIATION THERAPY TREATMENT PLANNING SYSTEM - A system and method for commissioning of a beam model for a three dimensional radiation therapy treatment planning system is described. The system includes an intensity modulated radiotherapy (IMRT) unit for generating a two dimensional intensity modulated beam pattern, a two dimensional diode array for detecting a two dimensional dose map for the beam pattern, and a processor configured to execute instructions for iteratively adjusting one or more parameters for the beam model, in order to increase agreement between the detected dose map and a calculated dose map calculated using the beam model. | 08-04-2011 |

| 20090097212 | Optimization of connector density and identification carrier for high density front plates - A high connector density printed circuit board, and high connector density device containing the same, including one or more of the following: a face plate; a plurality of connector ports in the face plate; a tab integral with the face plate label and bent to extend away from the face plate; information printed on the tab; the tab forming a plane at an angle of ninety degrees with respect to the face plate; the tab fabricated from a material having a combination of a thickness and a stiffness minimally able to resist a deformation resulting from a force of gravity; a second tab that is integral with the face plate and bent to extend away from the face plate; and the tabs do not infringe on an adjacent space occupied by another high connector density printed circuit board. | 04-16-2009 |
| 20090168348 | HIGH DENSITY COMPONENT ASSEMBLY METHOD AND APPARATUS - Apparatus and method for providing high density component assemblies, such as electromechanical or electro-optical assemblies. | 07-02-2009 |
| 20100107397 | METHOD OF INSTALLING VENTILATING FANS - An air-cooled electronic device includes a device housing having a bottom surface, and a motorized fan having a fan housing having a mounting hole, and having a hook projection secured to the bottom surface, the hook projection shaped and dimensioned to engage the mounting hole, and having an abutment, with the abutment, the hook and the mounting hole being arranged to secure the fan housing in a position without screws, rivets, or other hardware. | 05-06-2010 |

| 20080314392 | Limb Supporting Device - A device supports the weight of a limb of a person in a sling through a full range of motion in a generally lateral plane to reduce strain to the person during various procedures. The device comprises a base arm arranged to be supported on a supporting surface, a first swing arm pivotally supported on the base arm; a second swing arm pivotally supported on the first swing arm, a support member vertically slidably on the second swing arm, and an anchor supporting the sling thereon which is pivotal about a vertical axis on the support member. Height adjustment of the sling and anchor relative to the swing arms can be accomplished with a single handed lever operation. | 12-25-2008 |

| 20090032661 | Assembly for attaching a securing line to a roof beam structure - An assembly for attaching a securing line to a roof structure beam covered with a panel has a bracket, an attachment member, and a fastener. The attachment member has a hook on the second end thereof which is inserted through a panel aperture in the panel and hooked around the beam supporting the panel in abutment therewith. The first end of the attachment member extends outwardly through the panel aperture when the hook is hooked around the beam in abutment therewith and is extended through a member aperture of the bracket. The fastener is then fastened to the first end of the attachment member in abutment with the bracket and with the bracket abutting the panel, thus securely attaching the bracket to the panel and beam. The secure line, connected to the bracket, is thus secured to the panel. An optional reinforcing block is used for attaching the assembly to corrugated roof panels. | 02-05-2009 |

| 20080236937 | RESONATOR WITH INTERNAL SUPPLEMENTAL NOISE ATTENUATION DEVICE - A resonator for an induction system includes an inlet and outlet with a resonator cavity arranged therebetween. A tube is arranged within the resonator cavity and at least partially extends between the inlet and outlet. In one example, at least one supplemental noise attenuation device is in communication with the arcuate tube, such as a quarter wave tube and/or Helmholtz resonator. A large opening is provided in the tube that opens into the resonator cavity. In one example, the large opening is arranged on an outer radius side and faces a large cavity portion of the resonator cavity. Additional supplemental noise attenuation is provided by a collar arranged concentrically relative to the tube providing an annular quarter wave tube that is coaxial with the direction of flow from the outlet. | 10-02-2008 |
