| 20120062730 | AERIAL CAMERA SYSTEM AND METHOD FOR CORRECTING DISTORTIONS IN AN AERIAL PHOTOGRAPH - The invention relates to a method for correcting a distortion in an aerial photograph caused by a flight movement in the forward direction. The aerial photograph is captured by a surface sensor, the sensor lines of which sensor are exposed at different, successive exposure times, so that each individual sensor line senses a strip of terrain of the terrain flow over at the different exposure times. A relative flight altitude above the strips of terrain captured by the respective sensor line is assigned to the individual sensor lines. Furthermore, a compensation factor is separately determined for each of the individual sensor lines, wherein the factor depends on an air speed of the flying object, a focal length of the aerial camera and the relative flight altitude assigned to the respective sensor line, and corrects the distortion in the aerial photograph for the lines based on the respective compensation factor. | 03-15-2012 |
| 20110108312 | Shock damping system for a surface mounted vibration sensitive device - The inventive shock damping system for vibration sensitive surface mounted devices consists of an elastomeric material having conductive fiber material disposed between a printed circuit board (PCB) and a surface mounted device. Once disposed between PCB and surface mounted device, the elastomeric material, the PCB and the surface mounted device are compressed together with a component restraining system, to provide a secure electrical connection between one or more interconnect pads conductively attached to surface mounted device and the PCB. The elastomeric material allows signals and current to flow between surface mounted device and PCB without the use of any attached wires or leads while at the same time providing a system for damping any shocks or vibrations that may be transferred to surface mounted device through the PCB or through the protective component restraining system that encloses the device and the elastomeric material. | 05-12-2011 |
| 20090012712 | Assisted Seismic Measuring System Including GPS Receivers - A system for analyzing three-dimensional seismic data includes a plurality of digitizer units, each with a configuration of geophones, a data recording and control center, a base GPS receiver with an associated antenna with a substantially unrestricted view of the sky and at the respective digitizer units low-power slave GPS receivers that acquire and track GPS satellite signals using tracking assistance information provided by the base GPS receiver. The slave GPS receivers use the tracking assistance information to acquire and track GPS satellite signals that may be relatively weak at the receivers, due to conditions at the site, such as foliage canopies and so forth. The system processes range information provided by the slave GPS receivers over an extended period of time. In this way, the precise positions of the respective slave GPS receivers, and thus, the digitizer units, can be calculated, even if the slave GPS receivers are able to observe and collect data from sets of two or more satellites for only three or four relatively short time intervals at various sky positions during the extended period. The slave GPS receivers then locally produce for the digitizer units timing signals that are based on the GPS codes and synchronized across the system. If a given slave GPS receiver cannot, at a given time, track any GPS satellite signals, a nearby slave GPS receiver supplies the timing information required for the geophone data gathering operations. | 01-08-2009 |
