Title: Moving object and transient event detection using rotation strip aperture image measurements
Inventor: RAFANELLI GERALD L
IPC: G01S17/90
Filed: 1997-04-19
Abstract: A spinning aperture imaging radiometer sensor system (10) and data processing methods (20) for detecting moving objects derived from a plurality of image frames acquired by a strip aperture imaging sensor. A moving object in any invididual image frame results in a motion smear signature in the total synthesized image. The motion smear signature is processed to detect the moving objects. One embodiment of the system comprises a rotating strip aperture telescope (11), a two dimensional detector array (17) that detects images in the telescope's focal plane, a rotation compensation device (19) that prevents rotational smear during integration time of detectors of the array, a signal processor (18) that records a plurality of image frames of a scene imaged by the telescope as it rotates around its optical axis, and that implements method(s) (20) for detecting the moving objects present in the recorded images. A hierarchy of moving object detection processors (18) and methods (20) is disclosed that includes spatial, temporal, spatial frequency, and temporal frequency domain detection processors, and is compatible with multi-spectral background rejection techniques. Selection of the appropriate processing procedure and method depends upon the scenario, and the effective signal to noise ratio characteristics of the moving object. The present invention may be used for transient event detection.

Abstract: An interlayer insulation layer (20) is formed on a semiconductor substrate (1) and a groove of a wiring shape is formed in the interlayer insulation layer (20). Then, the groove is buried with conductor. A part of the conductor is covered with a mask material, and a part of the conductor not covered with the mask is etched to form a recess. Thus, a first wiring (25) is defined at a part of the conductor under the recess, and a columnar projection (26) to be a connecting portion of wirings is defined at a side of the recess on the first wiring (25). An insulation layer (28) is buried in the recess except for the upper surface of the columnar projection (26). A second wiring (30) covering at least a part of the exposed upper surface of the columnar projection (26) is formed.

Abstract: A digital broadcasting system capable of causing any of physical
channels selected by a broadcaster to be received as one of the channels
available to users which is different from the physical channel selected by the
broadcaster. For each of programs of each of the channels available to said
users, a program information record comprising PSI (program specific
information) is stored in a data base. The broadcaster is permitted to include,
in the PSI, channel mapping information whose mapping destination is a
channel (or a program) to be received instead of the channel for which said
program information is intended. The program information records is inserted
in broadcast transport streams on schedule and, if necessary, immediately
after the broadcaster have included the channel mapping information in the
PSI data.

Abstract: The disclosure relates to a plasma applicator (40) having a double-walled sapphire sleeve assembly (42,44) to provide a high efficiency cooling mechanism that is adapted for use with high power applications and aggressive plasma chemistries in the generation of a plasma. Plasma contained within a highly thermally emissive first sapphire member (42) heats the member, causing it to radiate thermal energy. The radiated thermal energy crosses a narrow gap and passes through an infrared-transparent second sapphire member (44). An infrared absorbing coolant fluid that exhibits negligible microwave absorption is flowed in a second gap (52) between the second sapphire member and a third member (36) and absorbs most of the infrared radiation over the fluid's bulk. The use of a bulk fluid optimizes the cooling of the plasma to reduce ion and use of a bulk fluid optimizes the cooling of the plasma to reduce ion and electron density and maximize reactive species output from the applicator to a vacuum process chamber (62).

Abstract: A felt (14) for use in a papermaking machine includes a
woven base fabric (18) and a batt layer (22) for supporting a
paper web. A flow control layer (20) is interposed between the
base fabric and the fibrous batt layer (22), to impede rewetting
of the paper web as the paper web exits a press nip of the
papermaking machine. The flow control layer (20) is formed of
a porous hydrophobic material. In use, pressure exerted by the
press nip forces water from the paper web through the batt layer
(22) and the flow control layer (20) into the base fabric (18),
and when the pressure is relieved, the hydrophobic properties of
the flow control layer (20) impede back-flow of water to the batt
layer (22) and thence to the paper web, thereby impeding
rewetting of the web. A preferred flow control layer (20) is
formed of a spunbonded filamentary nylon material which is non-circular
in cross-section, such as tri-lobed/triangular, and may
be treated with a hydrophobic chemical composition to enhance its
hydrophobic properties. The batt layer (22) and the base layer
(18) are preferably secured into the felt by a needling process.

Abstract: A process and a corresponding apparatus for improving the efficiency of an evaporation process are characterised in that by simulating the boiling process the advantages of negative pressure evaporation and steam compression are combined in a mode of operation similar to that of a heat pump. As illustrated in figure 1, a gas or gas mixture is compressed (3, 4) and pressed through a porous bottom (10) in the form of bubbles into the bottom of the liquid column, is aspirated at its surface, dried by compression and/or cooling and recirculated. The thus obtained energy balance makes it seem possible to cover most heat transport and transfer losses with the power dissipated by the compressor (3), in so far as the thus designed plant is correctly optimised. The plant was developed to solve the problems found in a desalinisation plant, but can be used for all concentration and evaporation processes. In the illustrated model, both fresh water and brine can be used.                           00000

behavior processor in the scheduler (14) that a cell is due for
transmission. The scheduler than issues a transmit credit for
