Abstract: Title:  IMPROVED METHOD AND APPARATUS FOR   RECONSTRUCTING MISSING COLOR SAMPLES      ABSTRACT OF THE DISCLOSURE An improved method and apparatus is provided for sensing scene light and providing sampled image data in three colors in response thereto.  The sampled image data is subsequently interpolated for the non-sampled colors and thereafter subtracted to provide two color difference signals.  The two color difference signals, in turn, are each median filtered and subsequently reconstructed in conjunction with the originally sampled image data to provide an image of the subject with substantially reduced color fringing.  The median filter preferably filters color difference signals corresponding to a select number of image sensing elements separated with respect to each other by non-select image sensing elements.

Abstract: METHOD AND DEVICE FOR MEASURING PERMEABILITY/  PENETRABILITY OF FABRIC IN A PAPER MACHINE                     ABSTRACT OF THE DISCLOSURE     The present invention concerns a method in a paper machine for the measurement of air penetrability or permeability of fabrics penetrable by air, in particular of a wire or felt.  In the method, the fabric penetrable by air such as a wire is passed over at least one roll, where a positive pressure is formed at an inlet side of the fabric with respect to the roll when the fabric runs and in an inlet nip formed between the moving fabric and a face of the roll, and a negative pressure is formed at an outlet side of the moving fabric with respect to the roll and in an outlet nip formed between the moving fabric and the roll face.  The positive pressure and negative pressure depend up on the permeability of the fabric penetrable by air.  According to the method, at least one device is mounted below the fabric penetrable by air such as a wire, this device being sealed relative to the moving roll face so that an at least partially closed pressure space is formed between the device, the roll face, and the fabric.  While the fabric penetrable by air such as the wire moves, the pressure is measured out of the pressure space and the permeability of the fabric penetrable by air is calculated from the measured pressure value.  The present invention also concerns a device for carrying out this method.

IPC: H02P9/00

Granted: 1992-06-16
Abstract: Abstract Method and apparatus of operating a variable speed power generation system in which the generated output of an induction generator is adjusted by controlling current in the secondary side of the induction generator.  Rotation speeds of the induction generator coupled to a prime mover are detected, a secondary current command for controlling the difference between a detected rotation speed and a speed command to zero is generated, and the current in the secondary side of the induction generator is controlled on the basis of the secondary current command.  In addition, the generated output of the induction generator is sequentially detected in order that the command value of the speed command is sequentially changed when a detected generated output shows a tendency to increase and, when a detected generated output shifts from an increasing tendency to a decreasing tendency, the command value of the speed command is once changed in the opposite direction against the changing direction up to that time, thereby maximizing the efficiency of the variable speed power generation system and reducing costs.

Granted: 1992-04-14
Abstract: ABSTRACT OF THE DISCLOSURE         In an adaptive digital  filter for use in an echo canceller or a decision feedback equalizer in a digital data transmission  system,  reduced  storage  and  lower  arithmetic processing speed are attained by subsampling,  in effect, the later parts of the waveform, i.e. the tail portion which changes relatively slowly. Such an adaptive digital filter comprises a storage device, such as a shift register, for storing a group of bits which represent symbols being transmitted in the digital data signal, a first stage for deriving an estimate for a first group of the stored bits, and at least one second stage for deriving an estimate for a second group of stored bits occurring earlier in time than the first group. The second stage has a summing device for summing the second group of bits to generate a quantity  representing  the  cumulative  sum of  the  symbols represented in the group, and a multiplier for multiplying the quantity by a single coefficient to obtain an echo estimate for the second stage.  The estimates for the first and second echo canceller stages are summed, then subtracted from the received digital data signal.  There will usually be a plurality of such second stages, each operative on a different group of bits of the digital data signal.

Abstract: An integral phase shifting network (215,216,217) of a transmitter filter (104) provides a means to reduce the size and increase the efficiency of an antenna coupling network. The network to shift the phase of the transmitter filter (104) is printed by depositing conductive material directly on a ceramic block (230) using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications. By utilizing an integral phase shifting network (215,216,217), either transmit filter (104) or receive filter (112) having a highly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.
