Abstract: A system and method for exploiting spectral absorption properties of water is disclosed. The system and method use spectral absorption properties of water to improve Short Wave InfraRed (SWIR) sensor (camera) performance in the presence of clouds. This is achieved partly by limiting the spectral passband of a sensor to a water absorption band, thereby improving Signal to Noise Ratio (SNR). Higher SNR permits improved CSO resolution. Further, higher SNR reduces the uncertainty in matching observations in one sensor to the epipolar lines of another sensor thus reducing the time needed to achieve unambiguous matches.

Abstract: A system for stitching images together is disclosed. The images are sometimes referred to as frames, such as frames in a video sequence. The system comprises one or more imagers (e.g. cameras) that work in coordination with a matching amount of custom code modules. The system achieves image stitching using approximately one third the Field of View (FOV) of each imager (camera) and also by increasing the number of imagers to be above a predetermined threshold. The system displays these stitched images or frames on a computer monitor, either in a still-image context but also in a video-context. Normally these tasks would involve a great detail of computation, but the system achieves these effects while managing the computational load. In stitching the images together, it is sometimes necessary to introduce some image distortion (faceting) in the combined image. The system ensures no gaps in any captured view, and assists in achieving full situational awareness for a viewer.

Abstract: A progressing cavity device operates as a motor to impart torque to a bit. A stator of the device defines an internal profile having uphole stages with a first dimension being less than a second dimension of downhole stage. A rotor has an external profile with a constant outer dimension along its length. Disposed in the stator, the rotor defines cavities with the stator and is rotatable with pumped fluid progressing in the cavities from the uphole to downhole to transfer torque to the drive toward the downhole end. Although the rotor is subjected at the downhole end to a reactive torque from the bit, the interference fit of the rotor's constant dimension with the stator's downhole stages is less than with the uphole stages, which can mitigate issues with heat buildup in the downhole stages. The device can also operates as a progressing cavity pump.
