IPC: H03M13/29
Filed: 1987-05-07
Abstract: A possible block diagram (Figure 1) makes up the system subject 
of this invention, in which the digital signal to be transmitted 
(TXSG) is coded through an external code device (EXCD); digital 
signal TXSG' so obtained (with a bit rate greater than 
TXSG) is used to modulate through modulator MOD 1, a transmission 
carrier later amplified by transmitter TEQ 1 and radiated 
by antenna ANT1. The R.F. carrier sent by the transmitter is received 
by the intermediate transponder through antenna ANT2, receiver 
REQ2 and demodulator DEM1 which reconstitute signal 
TXSG', save for transmission errors. The signal so received is 
once again coded by internal coder INCD, obtaining a new digital 
signal TXSG'' which has a bit rate even higher than TXSG' 
Such TXSG" signal is then used to modulate a second RF carrier 
by means of MOD2 modulator, later amplified by TEQ2 and radiated 
by antenna ANT3.  
     The RF carrier sent by the transponder is received by the receiver 
terminal through ANT4 and through receiver (REQ2) and demodulation 
(DEM2) units, a RXSG'' signal is rebuilt, coinciding, 
save for transmission errors, with signal TXSG" . Such signal is 
decoded by internal decoder INDC, obtaining a signal RXSG' 
which, save for transmission errors, coincides with signal 
TXSG'  
     This last signal is decoded by external decoder EXDC so as to 
rebuild signal RXSG, which save for transmission errors, coincides 
with transmitted signal TXSG.

Patent EP-0259659-A3 (EP)
IPC: G06F15/177
Filed: 1987-08-18
Abstract: A driver mechanism implemented in software and loaded in a computer 
supports multiple adapter cards in the computer under a single 
application programming interface. The driver mechanism enables multiple 
software subsystems in the computer which operate under a common 
application programming interface to be implemented on a plurality of 
different adapter cards resident within the computer. The driver 
mechanism is supported by data structures including an I/O address file 
containing information as to the addresses of each card installed in the 
computer, the card type and name of a corresponding directory file in the 
application programming interface. Directory files for the application 
programming interface comprise one file for each different card type 
installed in the computer. Two key functions performed by the driver 
mechanism are the INITIALIZE function and the OPEN function. The 
INITIALIZE function initializes the required adapter card hardware and 
tests its acceptability, and it also initializes a software control block 
structure for such adapter card to provide for the loading and concurrent 
execution of some number of processing functions. The OPEN function 
enables an application program to gain access to a required hardware 
resource on one or more of said adapter cards. Each of the hardware 
resources of an adapter card may be concurrently accessed by some 
predetermined number of applications.

IPC: H04L25/32
Filed: 1987-10-23
Abstract: The invention concerns a code with variable length of a type 
prefix/suffix ( [px..] sx), suitable for the parallel treatment 
of the words of said code, in particular for the compactation of 
said words into constant length packets at the transmission end 
and to the successive extraction at the receive end.  
     The code permits to separate at the receive end, the two 
operations of EXTRACTION and DECODING; essentially this may 
result in high speed applications wherein these operations cannot 
be performed within the clock cycle.  
     Besides said code permits the EXTRACTION operation to be 
simplified by considerably reducing the dimensions of the 
necessary hardware.  
     Its efficiency with particular distributions of messages is 
particularly high (97-98%).  
     Finally a detailed analysis is given of an application with a 
particular step code [px..] sx.

Filed: 1987-10-28
Abstract: To minimize the effects of magnetohydrodynamic 
surge forces acting on the liquid metal (32) in the collector 
gap (31) of an acyclic generator (10), fluid flow impedance members 
in the form of annular, axially spaced compliant brushes (44) 
are disposed in the outboard liquid metal containment gap (40b) 
defined between closely spaced, stator and rotor stepped 
surface formations (36, 38). These brushes (44) impede the 
communication to the liquid metal (32) in this containment 
gap (40b) of pressure fluctuations generated in the liquid 
metal (32) in the collector gap (31) resulting from variations in 
the generator current transiting the collector gap (31). A 
hydrostatic pressure head may thus be maintained 
consistently at a location intermediate the collector and 
containment gaps (31, 40b) for pumping the liquid metal (32) in a 
recirculating path.

Title: A method and apparatus for contextual data enhancement
IPC: G06T5/20
Filed: 1987-01-06
Abstract: A fingerprint classification and identification method and apparatus including circuitry to analyze a fingerprint image in the form of an N x M matrix of data elements, such data being analyzed in three basic scan windows which are clocked through a matrix array of data elements each containing either intensity data, direction data or both. The first window and its associated circuitry (114,140,200,220) serve to estimate data element directions by analyzing the intensity data in selected direction slits in the window to establish the slit having the ieast summed contrast between data elements spaced apart in the slit by a selected number of data elements. or to establish that there does not clearly exist such a slit. The second window passes through the matrix such that its data elements have already been passed through the circuitry (114,140,200,220) associated with the preliminary direction estimate window and have a preliminary direction estimate of one of the slit directions or "no direction". This second window and its associated circuitry (114,230) enhance the direction estimates made during passage of the first window according to various logic tests which generally seek to identify a slit direction which, along with the directions adjacent to it, are the directions of the predominant number of data elements in the window, or which is the average of the two slit directions which comprise the largest and second largest number of data elements, if they are sufficiently close in direction. The final window examines data elements having enhanced directions and with its associated circuitry (240,210,114), enhances the intensity data of a center data element in the third window, provided the center data element has an enhanced direction other than "no direction", according to an analysis of the center data element and the neighboring slit data elements in the slit with the direction of the enhanced direction of the center data element. The center data element and the neighboring slit data elements are compared with each other for direction data and intensity data and are compared with a mean intensity value for the scan window to derive a correction value for the center data element intensity to arrive at an enhanced intensity value. Separate logic is used to enhance the center data element intensity when it has a direction of "no direction", after which the data is passed into classification and matching circuitry (161).

and segments of that beam (23) are individually pulse 
width modulated at each of a number of sampling 
intervals during the sweep by monostable or bistable 
shutter pins (20) which either completely block or com­
pletely uncover the sectors which they control (22). An 
alternate embodiment adds beam width modulation as 
well, by making the shutter pins either completely 
block their sectors or uncover them only to the 
degree necessary for beam width modulation.

Title: Zoom lens driving apparatus
IPC: G02B7/10
Filed: 1988-12-28
Abstract: A zoom lens driving apparatus always detects a 
position (d;) of an image magnification varying lens section, 
and drives the image magnification varying lens section 
in accordance with a preset relationship between the 
position of the image magnification varying lens section 
and a zoom driving speed in such a manner that the driving 
speed becomes higher on one side where the focal length (fi) of 
the zoom lens corresponding to the position of the image 
magnification varying lens section is smaller than on another 
side where the focal length is large. Accordingly, the 
amount of focal shift, which in the zoom lens of the inner 
focusing system would otherwise abruptly increase with 
increasing focal length, is remarkably suppressed, so that 
an auto focus adjusting mechanism or a focus correcting 
device effective during zooming, provided in the zoom lens, 
can function satisfactorily as to follow the focal shift 
of the zoom lens, whereby the lens control of superior 
response can always be achieved.
Patent EP-0299823-A3 (EP)
IPC: G01V5/10
Filed: 1988-06-27
Abstract: A method for determining the porosity of a subsurface 
geological formation traversed by a borehole is provided. The 
method generally comprises obtaining a means which relates ranges 
of apparent formation porosity ( a ) as determined by a 
neutron-neutron log, formation fluid salinities, formation total 
capture cross sections (Σ), formation matrix and fluid 
constituents, and true formation porosity ( T ) according to 
a predetermined equation. The predetermined equation relates 
the apparent porosity to a function of a modified migration 
length which is obtained in a semi-empirical manner (i.e. physics 
modified by data). The modified migration length includes a 
slowing down length and a diffusion length, but causes at least 
the diffusion length to be a function of the slowing down length. 
The means which relates the apparent porosity to salinity, Σ, 
matrix and fluid constituents, and  T  solves a forward 
problem. Thus, the inverse problem of determining true porosity 
may be solved by obtaining determinations of salinity, formation 
matrix and fluid constituents, Σ, and  a , and using the 
relating means to provide the true porosity. The provided method 
properly and separately accounts for the effects of capture cross 
section and salinity, and can be used to correct the apparent 
porosity determination of a neutron-neutron tool, regardless of 
the formation matrix or formation fluid constituents.
