Title: Processing of memory access exceptions along with prefetched instructions within the instruction pipeline of a virtual memory system-based digital computer
IPC: G06F12/08
Filed: 1990-01-31
Abstract: A technique for processing memory access exceptions along with pre-fetched instructions in a pipelined instruction processing computer system is based upon the concept of pipelining exception information along with other parts of the instruction being executed. In response to the detection of access exceptions at a pipeline stage, corresponding fault information is generated and transferred along the pipeline. The fault information is acted upon only when the instruction reaches the execution stage(20) of the pipeline. Each stage of the instruction pipeline is ported into the front end of a memory unit (16) adapted to perform the virtual-to-physical address translation; each port being provided with means for storing virtual addresses accompanying an instruction as well as means for storing corresponding fault information. When a memory access exception is encountered at the front end of the memory unit, the fault information generated therefrom is loaded into the storage means and the port is prevented from accepting further references.

Title: Dual parison extrusion head for multi-layer blow moulding
IPC: B29C48/09
Filed: 1990-04-20
Abstract: Dual parison extrusion head (10) for multi-layer 
extrusion blow molding in which a die body surrounds two 
parallel spaced mandrels to form two cylindrical passages (12, 14) from 
which parisons are extruded. A series of resin supply 
conduits are provided for directing each resin to both 
passages. The series of conduits are axially spaced in the 
extrusion head to direct a plurality of plastic resins to each 
of the passages to form a multi-layer parison. The resin 
supply conduits (20, 22) are symmetrical about a vertical plane 
transversely bisecting the extrusion head between the two 
passages to produce flow and thermal symmetry in the resin to 
balance the resin flow to both passages. The resin supply 
conduits are configured so as to produce the dual parisons 
with the resin weld line of the multiple resin layers being 
located on the blow mold parting line. The resin conduits are 
positioned to minimize the center distance between parisons to 
reduce the size of the extrusion head. This is accomplished 
in part by feeding the resin downwardly before the resin flows 
into the cylindrical passages to form the parisons.

Patent EP-0653645-A3 (EP)
IPC: G01S15/88
Filed: 1991-05-27
Abstract: A distance sensing system (10) includes an ultrasonic transducer 
(XM1), a transceiver (12) and a microcontroller-based signal 
processing unit (14). The transducer (12) periodically generates 
and directs towards the terrain a dual frequency ultrasonic 
signal. Echo signals from the ground and/or any intervening crop 
or trash are reflected back to the transducer (12) and are 
processed. The system generates amplified and filtered echo 
envelope signals. Leading and trailing edge times are determined 
as the times the echo signals cross a threshold value which is a 
certain proportion of a maximum echo amplitude value. A near 
distance value is derived from the leading edge time of the first 
echo which exceeds a minimum amplitude. A far distance value is 
determined as the trailing edge time of the last echo signal which 
has an amplitude which exceeds a certain value. Multiple echo 
time and amplitude values are derived from the maximum amplitude 
echo. These values are used to prevent echoes which occur after 
the multiple echo time with less than a certain amplitude from 
being used in the determination of the far distance value. This 
far distance value represents the distance to ground and weaker, 
earlier echoes from trash or crop and later, multiple echoes may 
be ignored.

Title: Printing estimation method and apparatus
Inventor: SHIBATA MASARU
IPC: B41J2/01
Filed: 1992-05-13
Abstract: A table having a plurality of holding portions for holding recording heads to be tested is arranged to be pivotal between a printing position and a changing position, so that the recording head located at the changing position can be changed during estimation of the recording head located at the printing position. An estimation pattern in which dots are arranged so as not to contact each other is printed on a recording medium by the recording head held by the holding portion located at the printing position. The printed estimation pattern is read by an image pick-up device, and character amounts in units of dots are extracted from image data obtained by the image pick-up device. Pattern estimated values are calculated according to the dot character amounts, and whether or not the recording head is normal is judged on the basis of the calculated pattern estimated values. Another estimation pattern is printed on the recording medium. The printed pattern is read by the image pick-up device, and an edge image is extracted from density image data obtained by the image pick-up device. After enlargement/reduction processing is performed for the edge image, an edge image is extracted again. Shape character values in units of areas separated by edge lines of the edge image are obtained, and the pattern and a stain if any are discriminated based on the shape character values, thereby detecting a stain state.   A one-dimensional average density in the line direction of the pattern is obtained from the density image data, and a line width is obtained based on the average density. A stain is detected on the basis of the line width. Thus, whether or not a recording head is normal is estimated. <IMAGE>   <IMAGE>

Inventor: HORST ROBERT W
IPC: H04L12/56
Filed: 1996-06-05
Abstract: A data communicating device, having a number of
inputs whereat data is received for communication from one of
a number of outputs of the device, includes apparatus for
providing two levels of arbitration to select one of the
inputs for data communication to an output. The first (lower)
level of arbitration bases selection upon a round-robin order;
the second (higher) arbitration level selects inputs based
upon an indication from an input of an undue wait for access
to the output over a period of time. Each input is provided a
modulo-N counter, and a digital counter. Each time an input
contends for access to an output and loses to selection by the
output to another input, the modulo-N counter is incremented
by an assigned value for that input. When N is exceed without
access, the digital counter is incremented. The content of
the counter operates to force the high-level arbitration.

Abstract: An optical amplifier (e.g., 14) having high overall gain and low gain tilt, useful in an
optical transmission system or the like. The amplifier has a doped optical fiber (e.g.,
20) as the amplification medium and two pumps (e.g., 25, 26), the shorter
wavelength one propagating with the signal being amplified and the longer
wavelength one propagating opposite the signal being amplified. A wavelength
selective reflective fiber grating (e.g., 30) is disposed along the doped fiber to reflect
the second pump signal. The addition of the grating allows the amplifier to have a
higher gain with a lower gain tilt than amplifiers without the grating. Positioning the
grating along the fiber allows for the control of the overall gain with respect to the
gain tilt for a given fiber length.
