Patent EP-0395315-A2 (EP)
Inventor: DEPPE DENNIS G
IPC: H01S5/183
Filed: 1990-04-20
Abstract: An electrically pumped vertical cavity laser depends upon reflection as between an unaided distributed Bragg reflector (4) on one side of the cavity and a distributed Bragg reflector (8) supplemented by a metallic reflector (12) on the other. Placement of the shorter supplemented DBR on the p-conductivity type side of the cavity reduces the resistance of the electrical series pump path. Permitted use of an active region (1) of a thickness of 1µm or less in the lasing direction results in low lasing threshold. The structural approach is of significance for laser integration in integrated circuits, whether electro-optic or all-optic.

Abstract: Outbound signals carried over an electric power network are detected and crosstalk is rejected by sampling the waveform (V) in three segments (I, II, III) of each cycle. In the first segment (I) valid signals are always absent. Valid signals appear at the same time in both the second and third segments (II, III). Sample waveform values from alternate half cycles are compared to detect differences indicative of outbound signal information. The energy in each of the three segments (I, II, III) is compared with an energy threshold for that segment and a cycle under test is rejected when the energy in the first segment (I) exceeds the threshold for that first segment (I). A cycle under test is also rejected if the energy in the third segment (III) greatly exceeds the energy in the second segment (II). Signal detection thresholds for both signal strength and energy in the segments (I, II, III) are set recursively using actual samples acquired at the outbound detection site. These thresholds are sensitive to dynamic network changes.

IPC: E21B49/00

Abstract: The evaluation of fluid loss for subsurface fracturing is made through use of two test fracturing or "mini-frac" operations to determine formation parameters. A first mini-frac operation is performed to determine the fluid efficiency of the formation, and a second mini-frac operation is performed to determine a late time fluid leak-off coefficient. The data thus obtained are functionally related to simultaneously solve integral expressions to determine the total volume of fluid lost during pumping and the total volume of fluid lost during shut-in in response to an assumed spurt time. The fluid loss values are then functionally related to the established fluid efficiency to estimate an early time fluid leak-off coefficient. The early time fluid leak-off coefficient thus determined is then applied in a balance equation to verify the accuracy of such value in response to the assumed spurt time. The assumed spurt time may then be varied and the above fluid loss values iteratively reevaluated until the balance equation is satisfied within an acceptable range of tolerance.

Abstract: An image processing system including attenuation estimation logic 6 for estimating local attenuation coefficient values for segments of a scanned image from the amplitude values of scanned image pixels within said segments has micro-segmentation logic 3 for determining average amplitude values for micro-segments of the image, the micro-segments being smaller than the segments of the image and the average amplitude values of the micro-segments being used for estimating the attenuation coefficient values for the segments of the image. The invention enables individual features to be more clearly identified in the attentuation map than with prior images processing systems without the micro-segmentation logic with the result that it is more easy for the operator of the system to interpret the images.
