20080203778 | Seating Implement with Tablet - A seating implement has a base frame, a sitting surface, a back rest, and a tablet. The tablet is fastened to a support element provided on one side of the base frame by way of a linkage mechanism, so that the table can swivel between a substantially horizontal position of use and a position of non-use. The tablet is dimensioned to support a notebook computer and the support element has a section running in a substantially horizontal plane, on which the tablet is pivotally fastened by way of the linkage mechanism. The substantially horizontal section is oriented at an angle to the direction of the sitting surface, and the tablet can swivel about an axis substantially parallel to this section. | 08-28-2008 |
20120146367 | SWIVEL JOINT FOR SEATING IMPLEMENT - A swivel joint for pivotably coupling a tray to a support element of a seating implement. The swivel joint includes a tubular inner structure arranged substantially coaxially with and non-rotatably connectable to the support element, and a mounting structure at least partially surrounding the tubular inner structure in a radial direction. The mounting portion is pivotable relative to the tubular inner structure and rigidly coupled to the tray. The tubular inner structure includes at least one opening extending in the peripheral direction between two angular positions, and the mounting structure has at least one projection which projects in a radial direction and engages with the at least one opening of the tubular inner structure. The swivel joint provides additional structural integrity to compensate for loads on the tray and also provides a pivoting point to allow the tray to move easily between positions of use and non-use. | 06-14-2012 |

20090235727 | Sensor for a transmission-shift control, in particular of a motor vehicle - A sensor for a transmission-shift control of a motor vehicle is described. The sensor is connectable to a supply voltage (Vs) and to ground (GND). The sensor generates a signal voltage (Vout). The signal voltage (Vout) may assume two signals (high, low), both signals (high, low) being different from the supply voltage (Vs) and from ground (GND). | 09-24-2009 |
20100052214 | Assembly having a component enclosed by a housing, and device and method used in its manufacture - To provide an assembly which is as small as possible which contains a well-protected component and effectively dissipates heat, and to provide a device and a method for use in the rapid manufacture of such an assembly, an assembly includes a component and a housing from which the component is partially separated by narrow casting gaps filled with a casting compound containing a relatively large amount of filler. For the manufacture of such an assembly, a device is used for filling with casting compound and which includes a mounting for securing the assembly in a position which permits air to escape from the casting gaps, which have an external connection during filling. Also there are supply containers and supply lines for the casting compound which open into the casting gaps, and an apparatus for generating pressure. A method which is used to fill narrow casting gaps with casting compound by using such a device. The method involves introducing a casting compound of predetermined viscosity under pressure through the supply lines into the casting gaps, from which the air is displaced. | 03-04-2010 |

20100123072 | DETECTOR WITH MOUNTING HUB TO ISOLATE TEMPERATURE INDUCED STRAIN AND METHOD OF FABRICATING THE SAME - An imaging device and method of fabricating the same is disclosed. The imaging device may include an imaging sensor base, an image detector and a multilayer board. The imaging sensor base has a bonded hub having uniform flatness. The mounting hub sized to fit into a receptacle in the multilayer board. The image detector sized to match a size of the imaging sensor base and bonded to a top surface of the imaging sensor base. The imaging device may also include a readout integrated circuit (ROIC) sized to substantially match the size of the imaging sensor base and disposed on the image detector. A plurality of equi-spaced flexures and receptacles for receiving the plurality of flexures may also be used to maintain positional stability and minimize thermal strain. | 05-20-2010 |

20150292943 | OPTICAL SENSOR AND FILTER ASSEMBLY WITH EPOXY MOUNTING STRUCTURE AND METHOD OF ASSEMBLY - A mounting structure between the spectral filter and optical sensor includes one or more beads of epoxy that are bonded to the face of the sensor at locations adjacent and bonded to the edge of the spectral filter around its perimeter. Placement of the epoxy so that it bonds to the edge of the spectral filter improves the robustness of the package to sheer stresses. Placement of the epoxy at the edge, suitably in discrete spot bonds, also avoids putting epoxy in the optical path, contaminating the optically active area or using epoxy to control the gap height. Alignment of the spectral filter in the plane (x,y) may be achieved using fiducial marks on the sensor and filter. Alignment of the spectral filter out of the plane (z) may be achieved using incompressible spacer balls that set the gap height precisely to the diameter of the ball. Alternately, the spectral filter may be placed in direct contact with the optically active area of the sensor. | 10-15-2015 |
