| 20100264311 | DEVICE WITH A SANDWICH STRUCTURE FOR DETECTING THERMAL RADIATION, AND METHOD FOR THE PRODUCTION THEREOF - In a device for the detection of thermal radiation which and a method for production of such a device, a stack is formed with at least one detector support having at least one detector element for the conversion of the thermal radiation into an electric signal, at least one circuit support with at least one read-out circuit for reading out the electrical signal and at least one cover to shield the detector element, wherein the detector support and the cover are so arranged with respect to one another that a first stack cavity bounded by the detector support and the cover is provided between the detector element of the detector support and the cover and that the circuit support and the detector support are so arranged with respect to one another that at least one second stack cavity bounded by the circuit support and the detector support is provided between detector support and the circuit support and that the first hollow stack support and/or the second stack cavity is evacuated or can be evacuated. Preferably, the detector support, circuit support and cover are made of silicon. The manufacturing operation takes place at wafer-level. Functionalized silicon-substrates are stacked upon one another, firmly bonded together and subsequently sub-divided. Preferably, the detector elements are pyro-electric detector elements. The device finds application in motion detector, presence reporters and thermal-image cameras. | 10-21-2010 |
| 20110006211 | DEVICE HAVING A MEMBRANE STRUCTURE FOR DETECTING THERMAL RADIATION, AND METHOD FOR PRODUCTION THEREOF - In a device for detecting thermal radiation, at least one membrane is provided on which at least one thermal detector element is mounted for the conversion of the thermal radiation into an electric signal and at least one circuit support for carrying the membrane and for carrying at least one readout circuit for reading out the electrical signal, the detector element and the readout circuit being connected together electrically by an electric contact which passes through the membrane. In addition, a method of producing the device with the following method steps is provided: a) provision of the membrane with the detector element and of at least one electrical through-connection and provision of the circuit support and b) bringing together the membrane and the circuit support in such a manner that the detector element and the readout circuit are connected together electrically by an electrical contact passing through the membrane. Production activity is preferably carried out at wafer level: functionalised silicon substrates are stacked upon one another, firmly bonded to one another and then divided into individual elements. Preferably, the detector elements comprise of pyro-electrical detector elements. The device finds application in motion detectors, presence detectors and in thermal imaging cameras. | 01-13-2011 |
| 20110049369 | Device to detect thermal radiation with high resolution method to manufacture and use the device - A device to detect thermal radiation has a membrane and at least two detector elements that are respectively set up to transduce thermal radiation into an electrical signal and are mounted situated next to one another on the membrane, wherein at least one heat dissipation path is provided on the side of the membrane facing towards the detector elements and/or on the side of the membrane facing away from the detector elements, which heat dissipation path has a higher heat conductivity than the membrane and is connected with the detector elements in a heat-conductive manner via the membrane so that heat can be discharged from the detector elements with the heat dissipation path, whereby the response time of the detector elements is short; and wherein at least one heat barrier that has a lower heat conductivity than the membrane and extends between the detector elements is provided integrated into the membrane, such that a heat conduction in the membrane from the one detector element to the other detector element is prevented by the heat barrier; whereby the crosstalk of the detector elements is low. | 03-03-2011 |

| 20090045678 | Method and Device for Redundantly Supplying Several Electric Servomotors or Drive Motors by Means of a Common Power Electronics Unit - A method and a device for redundantly supplying several electric servomotors or drive motors by a common power electronics unit particularly in an aircraft, wherein the power electronics unit contains a number of electronic motor control units, and wherein the electric motors are operated with nominal power if the electronic motor control units are fully functional. The motors are operated with the available residual power of the motor control units if partial failure of the motor control units occurs. The motors may be operated sequentially or simultaneously. | 02-19-2009 |
| 20100125380 | Method And Device For Fault Detection In The Load Path Of A Spindle Actuator - A method and a device for fault detection in the load path of a spindle actuator which is provided for actuating an aerodynamically active surface, in particular a high-lift flap of an aircraft, wherein the spindle actuator has a redundant load path which is formed by a spindle and a secondary connection which are connected rotationally fixedly to one another on the driven side and are coupled to the surface to be actuated and which are assigned separate load paths on the drive side, whereof the primary load path contains a primary spindle which is driven by a motor and can be fixed in its rotational movement by a primary brake, and the secondary load path contains the secondary inner connection, which is in particular arranged concentrically in the primary spindle, which can be fixed in its rotational movement by a secondary brake, in which output signals representing the turning position of the spindle, which are generated by means of at least one turning position sensor which is coupled to the primary spindle on the drive side, are detected and evaluated, wherein: fixing the secondary connection in its rotational movement is achieved by means of the secondary brake; the redundant load path is put under load, when the primary brake is released, the load being applied via a predefined torque by the motor as far as the secondary brake is fixing the secondary connection; and the detection of a fault is evaluated when a change in the turning position, which lies outside the tolerance range predefined for an intact spindle actuator, is detected at the turning position sensor coupled to the primary spindle. | 05-20-2010 |

| 20100200222 | Method and apparatus for performing cementing operations - A remotely operated lifting top drive cement head is provided having a high tensile strength, as well as the ability to swivel or rotate about a central vertical axis. The cement head permits selective launching of darts, setting plugs, balls or other objects which can be held in place within the cement head without being damaged or washed away by slurry flow, but which can be beneficially launched into said slurry flow at desired point(s) during the cementing process. The cement head can be remotely operated without requiring the lifting of personnel off the rig floor to actuate the tool or observe tool status. | 08-12-2010 |
| 20110048710 | Method and apparatus for performing cementing operations on top drive rigs. - A remotely operated lifting top drive cement head is provided having a high tensile strength, as well as the ability to swivel or rotate about a central vertical axis. The cement head permits selective launching of darts, setting plugs, balls or other objects which can be held in place within the cement head without being damaged or washed away by slurry flow, but which can be beneficially launched into said slurry flow at desired point(s) during the cementing process. The internal components of the cement head can be easily accessed using interrupted thread connections that can be quickly and easy connected and disconnected in the field without requiring specialized equipment.
