Title: Recursive noise reduction filter for video components
IPC: H04N5/21
Filed: 1989-09-13
Abstract: A recursive noise reduction filter for video 
components reduces the noise bandwidth of a signal 
without degrading the signal spectrum. Demodulated 
chrominance or peak detected chrominance from a video 
signal output by a video system in response to a video 
test signal is input to the recursive noise reduction 
filter (24) which acts as a comb filter to suppress noise 
significantly at frequencies other than harmonics of 
the horizontal line rate. The signal is scaled by a 
first attenuator (30) having a scaling factor of (1-a), 
where (a) is less than one, and input to a summing 
circuit (32). Also input to the summing circuit is a 
delayed signal from a prior horizontal line scaled by 
the scaling factor (a). The output of the summing 
circuit is a filtered output signal. The signal is 
sampled only during horizontal lines that have the 
video test signal and is stored for subsequent 
accumulation with other horizontal lines also having 
the video test signal. The filter serves to add the 
vertically correlated part of the signal corresponding 
to the video test signal while averaging out the 
noise, thus improving the overall signal to noise 
ratio without degrading the signal spectrum and, 
hence, enhancing differential gain and phase 
measurements.

Title: Method of magneto-optically recording/erasing information and magneto-optical information storage medium
IPC: G11B11/105
Filed: 1989-09-29
Abstract: A magneto-optical recording medium including a 
recording layer (2) and a bias layer (4) being stacked 
one upon the other to apply coupling interaction which 
is mainly magnetostatic interaction to each other, the 
bias layer (2) having a magnetization-reversing tempera­
ture higher than that of the recording layer. The 
medium is irradiated with laser beam pulses having a 
recording level and an erasing level lower than the 
recording level, thereby recording and erasing the 
information. When the medium is irradiated with the 
laser beam pulse having the recording level and the 
irradiated region is cooled to the magnetization revers­
ing temperature T rR , the magnetization of the beam-­
irradiated region of the recording layer (2) is aligned 
with a direction of the leakage magnetic field leaking 
from the recording layer (2). When the medium is irra­
diated with the laser beam pulse having the erase level 
and the irradiated region is cooled to T rR , the direc­
tion of magnetization of the beam-irradiated region of 
the recording layer (2) is aligned with a direction of 
the leakage magnetic field applied from the bias layer 
to the recording layer.

Title: Remote agent operation for automatic call distributors
IPC: H04M3/42
Filed: 1989-12-08
Abstract: This invention relates to an automatic call distributor (ACD) 
arrangement for economically providing ACD service from remote ACD agents. A 
remote ACD agent position is located near a local switching system which connects 
to an ACD host switch via a telecommunication network comprising a common 
channel signalling facility. The remote ACD agent position and an ACD process at 
the host switch communicate with each other by sending data messages via the 
common channel signalling facility and the local switching system. A front-end 
process at the host switch acts as a data message interface between the remote ACD 
agent position and the ACD process by performing protocol conversion between the 
common channel signalling facility message format and the ACD process message 
format. The front-end process also establishes a voice connection between the host 
switch and the remote ACD agent position. The ACD process connects incoming 
customer calls to the remote ACD agent position for servicing of the call by the 
remote ACD agent. Advantageously, this arrangement permits the complex ACD 
software to treat remote and local agent positions alike and uses an economic 
communication arrangement for connecting the remote agent position to the host 
switch.

Title: Apparatus for dry treatment of a fabric
IPC: F26B13/10
Filed: 1989-05-03
Abstract: An apparatus for the dry treatment of a fabric (4) in 
which the fabric passes repeatedly from a first chamber (2) 
to a second chamber (20) and back again through a passage 
(38) in which air is blown in the appropriate direction. 
Within each chamber (2, 20) facing the port (40) of the 
passage, there is a fabric receiving device (96) which 
allows the air therethrough and receives the fabric (4) 
without retaining it, whereby the fabric is piled in 
orderly fashion on a platform (92) of the corresponding 
chamber. The device (96) avoids irregular piling and 
entanglement of the fabric (4) in the lengthwise direction.  
     Adjustment of the control means (60, 62) of access of 
the air to the passage (38) opposes a main current to a 
secondary current of air, producing compacting of the 
fabric (4).

Title: On-line reconstruction of a failed redundant array system
IPC: G06F11/14
Filed: 1991-10-15
Abstract: A method for on-line reconstruction of a failed storage unit in a redundant array system. After providing a replacement storage unit for the failed storage unit, reconstruction begins for each data stripe in the array. General reconstruction consists of applying an error-correction operation (such as an XOR operation on data blocks and a corresponding parity block) to the data blocks from the remaining storage units in the redundancy group, and storing the result in the corresponding block of the replacement storage unit. If a Read operation is requested by the CPU for a data block on the replacement storage unit, then a concurrent Read task is executed which reconstructs the stripe containing the requested data block. If a Read operation is requested by the CPU for a data block not on the replacement storage unit, a concurrent Read task is executed which performs a normal Read. If a Write operation is requested for any data block, then a concurrent Write task is executed which performs a Read-Modify-Write sequence in the general case (the Read operation being performed in accordance with the above rules).
