Title: Opto-electronic directional switch
IPC: G02F1/29
Filed: 1987-03-10
Abstract: An opto-electronic switch which shows a good signal rejection ratio between modes is also of particularly small dimensions. The switch comprises a semiconductor laser 1 having four contacts 12, 12', 13, 13' which provide gain guiding under two stripe windows 18, 19. By varying the bias currents supplied to the individual contacts 12, 12', 13, 13', or by inputting optical control signals to the waveguiding channels under the stripe windows 18, 19, different configurations of optical output from the laser 1 can be achieved. The two contacts, 12, 12' and 13, 13', associated with each stripe window 18, 19 are effectively a single stripe contact with a discontinuity. It is thought that diffractive transverse coupling at the discontinuity allows the use of a shorter device than in known directional switches. With feedback, the switch operates as a memory device. The switch finds particular application in optical communications, for instance in signal routing.

Abstract: Improved catoptric reduction imaging systems of a 
quassi-Cassegrainian type are presented wherein light 
from an object enters an imaging system through an 
aperture in one mirror of an imaging system and leaves 
the imaging system through an aperture in another 
mirror of the imaging system to form an image. In 
each imaging system, the sums of the inverses of the 
radii of the mirrors effecting each reflection are 
constrained to be substantially zero.  
     In a first improved catoptric reduction imaging 
system, two mirrors (12, 14), one convex and one concave of 
equal base radii, are disposed axially, light from the 
object (16) enters the imaging system through an aperture in 
the concave mirror (14), reflects from the convex mirror (12) to 
the concave mirror and reflects from the concave 
mirror to form the image (20) positioned beyond the convex 
mirror through an aperture (22) in the convex mirror.  
     Three alternative arrangements are disclosed.
Patent EP-0278187-A3 (EP)
IPC: G01G21/00
Filed: 1987-11-26
Abstract: A dual -range analog-to-digital convertor for the 
improved operation of an electronic computing scale provides 
significantly increased resolution in a first weight sub-range 
(0-12 pounds in the illustrative embodiment) and e coarser 
resolution in a second weight sub-range (11-100 pounds). The 
raw load cell voltage is communicated along first and second 
branches (27,30 ; 27,32), and subjected to a different trans­
formation in each branch to produce first and second transformed 
voltages. In the first branch (27,30), raw voltages correspon­
ding to weights in the low sub-range are mapped onto a desired 
sub-range of voltages. In the second branch (27,32), raw 
voltages corresponding to weights in the high sub-range are 
mapped onto a second sub-range of voltages. Depending on the 
weight on the scale, one or the other of the transformed 
voltages is applied through switch means (35) to the ADC input 
terminal (22), and the digital output is scaled accordingly. 
The circuitry includes a range flag (37) and logic circuitry 
(25) for sensing the digital ADC output, and controlling the 
range flag. When the range flag is in a first state (signi­
fying that the low weight sub-range is selected) and the ADC 
output signifies a weight above the low sub-range, the range 
flag is set to a second state (high weight sub-range). 
Similarly, when the range flag is in the second state and the 
ADC output signifies a weight below the high sub-range, the 
range flag is set to the first state.

Patent EP-0281946-A3 (EP)
IPC: E21B47/01
Filed: 1988-03-03
Abstract: An inflatable attenuator (40) having an inflatable resilient 
bladder (46) enclosed by a perforated protective cylindrical housing 
is positioned in a liquid column in a well (10) below (and if desired 
another inflatable attenuator is also positioned above) an impul­
sive energy source (20) in the liquid column. The housing (42) has an 
exterior diameter slightly less than the interior diameter of the 
well (10). The bladder (46) is inflated when in the liquid column by gas 
supplied from a pressurized gas container attached to the attenu­
ator or is supplied with pressurized gas through a hose line 
from a source of pressurized gas located on the surface of the 
Earth near the mouth of the well. A pressure-regulator respon­
sive to the ambient hydrostatic pressure in the liquid column 
near the pressure regulator serves to maintain the pressure of 
the gas within the bladder at a regulated pressure at least 
equal to the ambient pressure in the liquid column where it is 
located. A pressure-relief valve (50) releases pressurized gas from 
the bladder to prevent the pressure inside of the bladder from 
exceeding a predetermined differential in pressure between the 
inside of the bladder and ambient hydrostatic pressure so that 
the bladder (46) will not rupture when the attenuator (40) is being 
elevated in the well. The inflated bladder (46) attenuates tube waves 
(32) traveling along the liquid column in the well (10) from an impulsive 
source (20) of seismic energy waves when employed in the liquid col­
umn above or below the energy source. The upwardly traveling 
tube waves (35) may alternatively be dissipated by releasing numerous 
gas bubbles (72) in the upper portion of the liquid column to generate 
a bubble barrier in the upper portion of the liquid column. 
A further embodiment includes two bladders, including a tapered 
upper bladder which flares outwardly and downwardly and a 
cylindrical lower bladder. The perforated protective housing 
is omitted, and enlarged annular shoulders protect these 
bladders from abrasion against the wall of the well.

Patent EP-0276170-A3 (EP)
IPC: H05G1/36
Filed: 1988-01-22
Abstract: A voltage signal (29,42) proportional to the 
brightness of an x-ray image is derived. In a mA loop 
the ratio of a reference voltage to brightness is 
determined (in 70). If the brightness ratio does not 
equal 1 it causes the x-ray tube current controller 
(21,61) to adjust current (mA) to eliminate the error. 
A command proportionate to the ratio is stored (in 71) 
until the next image frame. In a kV loop a ratio of 
the last mA command and a set limit for mA is taken (in 
80). This error ratio is multiplied (in 83) by the 
brightness ratio to provide a kV control ratio 
indicative to how much of the brightness error the kV 
loop is obliged to correct. The kV control ratio is 
corrected for nonlinearity between kV change and 
brightness change and the resulting command is used to 
adjust the kV applied to the x-ray tube anode. In a 
video gain control loop a ratio is taken (in 110) 
between the stored last brightness ratio of mA command 
and maximum mA command limit and the brightness change 
resulting from the last kV control command is ratioed 
(in 114) to the maximum brightness factor limit. The 
result of multiplying (in117) the last two mentioned 
ratios and the brightness ratio is the new video gain 
(VG) control signal. The VG signal is used to adjust 
the f-stop of the video camera and the electronic gain 
to change brightness.

is formed as woven sheets from filament yarns resistant to high 
temperatures. Balanced fabric sheets are sectioned at a 
predetermined angle to the filament yarns to form balanced fabric 
plies. The yarns of the balanced fabric plies are orientated at 
the predetermined angle with respect to the longitudinal axis of 
the composite hose such that the composite hose has a 
predetermined longitudinal flexibility to compensate for stress 
effects resulting from high temperatures, high pressures and/or 
vibrations. Concomitantly, the balanced fabric plies restrict the 
radial flexibility of the composite hose to preclude collapse or 
ballooning of the hose during start up, irregular or steady state 
operation.

Title: Integrated cache unit
IPC: G06F12/0804
Filed: 1989-01-18
Abstract: Methods and apparatus are disclosed for realizing 
an integrated cache unit (ICU), that is a cache unit comprising 
both a cache memory and a cache controller on a single chip. 
The novel ICU is capable of being programmed, supports high 
speed data and instruction processing applications in both 
Reduced Instruction Set Computers (RISC) and non-RISC archi­
tecture environments, and supports high speed processing 
applications in both single and multiprocessor systems. 
According to the preferred embodiment of the invention, an ICU 
is disclosed which includes 8k bytes of data, 512-20 bit words 
of tags, and the necessary control to fully implement cache 
functions. The preferred ICU has two buses, one for the 
processor interface and the other for a memory interface. The 
ICU supports single, burst and pipelined processor accesses 
and is capable of operating at frequencies in excess of 
25 megahertz, achieving processor access times of two cycles 
for the first access in a sequence, and one cycle for burst 
mode or pipelined accesses. It can be used as either an 
instruction or data cache with flexible internal cache 
organization. A RISC processor and two ICUs (for instruction 
and data cache) implements a very high performance processor 
with 16 k bytes of cache. Larger caches can be designed by 
using additional ICUs which, according to the preferred embodi­
ment of the invention, are modular. Further features include 
flexible and extensive multiprocessor support hardware, low 
power requirements, and support of a combination of bus 
watching, ownership schemes, software control and hardware 
control schemes which may be used with the novel ICU to achieve 
cache consistency.
