Title: Optical equipment of fiber laser doppler velocimeter
IPC: G01S17/58
Filed: 1990-02-13
Abstract: A beam expander (32,33) is used with a perforated concave lens (32) 
and a plano convex lens (33) to expand a beam diameter to make a small 
measurement volume (0) to increase an intensity of light scattered, 
which contributes a reduction of a number of an optical 
components and a complicated optical adjustment, and makes a 
small probe diameter. The perforated part of the expand lens (32b) 
plays a role of a space filter to cut off troublesome light 
scattered when a beam passes through a lens. A three points 
supporting mechanism adjustment of the focused beam positioning 
into the fiber core and the incident beam aperture adjustment in 
the fiber's numerical aperture are used. A high resolution of 
the adjustment is achieved so that a high transmitting efficiency 
of a laser power into the fiber is achieved.

Title: Method and apparatus for optimizing element placement and deciding the optimal element placement
IPC: G06F17/50
Filed: 1990-03-15
Abstract: Element placement optimizing method and apparatus 
for determining an optimum placement of constituent elements 
for an LSI or the like. A parallel processing type computer 
system (14) including a plurality of CPUs is used. Initial 
placement setting means (10, 11) are establishing an initial 
element placement and a selecting means (12, 13, 14) selects 
a number of paired element candidates for position exchange 
from the initial placement, the number being equal to that of 
CPUs. A cost improvement value resulting from the exchange is 
determined for each of the paired candidates by the associated 
CPU (14). The exchange of the elements is performed for the 
paired element candidates for which the cost improvement value 
is maximum of those determined by the CPUs. By repeating the 
exchange, an optimum element placement is determined and 
output by output means (16).

Title: Adaptive interframe prediction coded video communications system
IPC: G06T9/00
Filed: 1990-05-11
Abstract: At the transmit end of a video communications system, a first motion 
vector is derived from successive frames during a frame transmit mode 
and a second motion vector is derived during or immediately following a 
frame discard mode. An interframe predicted error signal is generated 
which is representative of the difference between each input frame and a 
motion-compensated, previous frame during the frame transmit mode, 
the difference being zero during the frame discard mode. The predicted 
error signal and the vectors are transmitted to the receive end of the 
system. In a first embodiment, the second motion vector is derived at the 
transmit end from frames spaced apart by a discarded frame, and at the 
receive end, original frames are recovered from the predicted error signal 
as well as from the first and second motion vectors, and the second 
motion vector is down-scaled and evaluated whether it is valid or not. 
During frame discard mode, motion compensation is performed on the 
recovered frame using the down-scaled vector in response to a valid 
evaluation, but no compensation is performed if invalid evaluation is 
made. In a second embodiment, the second motion vector is derived at 
the transmit end from successive frames using a larger block size than 
that used in the first motion vector. At the receive end, the first motion 
vector as well as the error signal are used in recovering original frames. 
During the frame discard mode, the second vector is simply used for 
motion compensation.

Patent EP-0403267-A3 (EP)
Title: Semiconductor device
IPC: H01L27/088
Filed: 1990-06-13
Abstract: The semiconductor device of the invention possesses 
a combined structure of several transistors. Hitherto, 
sharing of gate in the circuit composition or sharing of 
drain of preceding transistor and source of succeeding 
transistor has been known, but the invention includes 
plural transistors in which the transistors themselves 
share a channel region. In other words, the semiconduc­
tor device of the invention is compounded in a form 
of sharing the gate and source by plural transistors, 
and possesses three or more sources and drains.  
     In such constitution, not only the drain current 
is determined depending on the potential difference 
of the pair of source and drain, but also the individual 
drain current increases or decreases depending on the 
voltage application condition (potential difference) 
of all source and drain terminals. In the invention, 
having three or more sources and drains, the drain cur­
rent increases or decreases depending on the magnitude 
of the voltage applied to them. Therefore, assuming 
one of the plurality of source and drain terminals to 
be a control terminal (disturbance terminal) of the 
transistor having other pair of source and drain, by 
applying a proper voltage to the source and drain termi­
nals, instability or drift of the transistor operation 
may be intentionally produced.

Patent EP-0605244-A3 (EP)
Inventor: HAUCK JOHN A
IPC: A61N1/37
Filed: 1993-12-24
Abstract: A cardiac pacemaker signal processing circuit adapted
to obtain an evoked ECG signal. The circuit senses the
electrical signals of the ring and tip electrodes in the
unipolar mode from the bipolar lead after the electrical
pacing stimulus has been applied to contract the ventricle
of the heart. The residual oppositely polarized potentials
at the ring and tip electrode, as well as the sensed evoked
ECG signals, are added together to cancel out the opposing
residual potentials, but to add the common polarized ECG
signal. Thus, a high quality evoked ECG signal is
obtained, free of the residual potentials, and subsequently
utilized by R-wave detection circuits for sensing the QRS
complex. The circuit includes compensating signal
processing circuits to provide time domain signal
processing weighting functions to match exponential time
delay of the tip and ring electrodes, and includes
amplitude adjusting compensation as well. Thus, the
absolute amplitudes of the opposite polarized residual
potentials will be adjusted to be equal, are summed, and
canceled or nulled at the appropriate time in the time
domain. Both biphasic and triphasic pace pulse techniques
are not required, the pace pulse amplitude can be reduced
to extend the battery life of the pacemaker. Further, the
post pace re-charging cycle is only interrupted and
undertaken passively to, again, reduce current drain on the
battery. Classic R-wave detection circuits are adaptable
to the signal processing circuit of the present invention.
