Title: Half tone printing or display apparatus
IPC: B41J2/52
Filed: 1988-12-19
Abstract: A method and apparatus for effecting enhanced 
digital half-tone reproduction using a binary 
displaying device promotes good colour tone fidelity 
while retaining high spatial resolution. The input 
image is subdivided into a matrix of component pixels 
each representing an intensity value at a 
corresponding image location. The intensity is 
related to the maximum possible intensity of the pixel 
and the decision to print is made on the basis of the 
intensity relation of the pixel and an internally 
generated pseudo-random number. In one embodiment a 
number of display deciding matrices are stored in 
memory and one matrix is selected in accordance with 
the intensity relation of the pixel and a location in 
the selected matrix is accessed in accordance with a 
pseudo-random number with the information at that 
location used to decide whether or not to display the 
pixel.

Title: Fiber-optic physiological probes
IPC: G01N21/76
Filed: 1989-07-19
Abstract: Fiber-optic sensors suitable for monitoring physiological analyte 
concentration. An analyte-permeable matrix is disposed in the light path defined 
by the axial core at one end of an optical fiber segment. The matrix contains an 
indicator molecule covalently linked to a polymer, preferably methyl 
methacrylate/methacrylamidopropyltrimethylammonium chloride, N-vinyl­
pyrrolidone/p-aminostyrene, methyl methacrylate/hydroxymethyl methacrylate, 
methyl methacrylate/N-vinylpyrrolidone, or methyl methacrylate/acrylic acid. In 
representative embodiments, the polymer is approximately 94:6 mole/mole 
percent of either methyl methacrylate/methacrylamidopropyltrimethylammonium 
chloride or N-vinylpyrrolidone/p-aminostyrene copolymer. Drift-free 
performance is obtained with such sensors having analyte-permeable matrices of 
significantly less than about 70 microns in thickness. The indicator molecule may 
be covalently linked to the polymer through an aminoarylalkylamine, such as 
4-(aminophenyl)-ethylamine or 4-(aminophenyl)-propylamine. The indicator 
molecule may be an absorptive molecule, such as phenol red or 
carboxynaphthophthalein (hydrogen ion analyte), in which case the indicator 
molecule may be covalently linked to the polymer through either an azo-amide or 
an amidyl-amide linkage. The indicator molecule may be a luminescent molecule, 
such as carboxynaphthofluorescein (hydrogen ion analyte) or an oxygen-quenchable 
porphyrin derivative. The sensor may have a reflector disposed in the light path 
distal with respect to the optical fiber segment to the analyte-permeable matrix. 
Suitable reflectors include gold foil or films of titanium dioxide, zinc oxide, or 
barium sulfate. A pCO₂ sensor is configured with a gas-permeable but ion-­
impermeable membrane encapsulating an analyte-permeable matrix that includes 
a base having a pKa ranging from about 6.0 to about 7.8. The outer membrane 
may be a silicone, polycarbonate, or urethane. The base may be an inorganic salt, 
such as bicarbonate, in which case the analyte-permeable matrix should include an 
antioxidant. Alternatively, the base may be a polymeric base containing, e.g., 
2-vinylpyridine, 4-vinylpyridine, histamine, 1-vinylimidazole, or 
4-vinylimadazole. Gas-permeability is afforded to the matrix by a minor 
component of hydrophilic polymer such as polyethylene glycol. A plurality of the 
pH, pO₂, and pCO₂ sensors may be disposed together in substantially coterminal 
array to make a multi-variable probe, which may also include a thermocouple 
wire.

Title: Method of manufacture of an electrical terminal on an injection molding nozzle
IPC: H01R9/00
Filed: 1989-08-09
Abstract: A method of making an electrically insulated terminal (12) in an injection nozzle (10). After the heating element (44) is wound in a spiral channel on the outer surface (36) of the main body portion (14) of the nozzle the rear end (104) projects radially out an opening (80) in the collar portion (16). The casing (102) is stripped from the heating element to expose the resistance wire (112) adjacent the rear end. A steel plug (78) having a central bore (76) therethrough is slipped over the projecting rear end and welded into place in the opening. A steel terminal body (82) is made with a central bore (106) and a threaded front portion (84) to receive an external power lead (118). The casing (102) of the portion of the heating element (104) projecting from the plug and a rear portion (88) of the terminal body (82) are coated with insulating material (92). A protective cap (94) is securely swaged over the coating on the rear portion. The assembled cap and body are slipped over the rear end of the heating element and welded to the matching front face (100) of the plug (78). The exposed resistance wire (112) is welded to the terminal body (82). This structurally secures the terminal body against torque from connecting and disconnecting the external lead and electrically insulates it from the rest of the nozzle, while electrically connecting it to the resistance wire. In an alternate embodiment, the connections are made while integrally brazing the nozzle in a vacuum furnace.

Title: Image transformation method and device
IPC: H04N7/36
Filed: 1989-09-14
Abstract: A rectangular source image formed by pixels in a two-­
axis coordinate system is transformed to a destination image 
by mapping vertices of the source image onto vertices of the 
destination image, then mapping edges of the destination 
image onto edges of the source image, mapping scan lines in 
the destination image onto the source image, and assigning 
to pixels on these scan lines the values of corresponding 
pixels in the source image. DDA algorithms are employed for 
the edge mapping and scan line mapping steps. This method 
enables arbitrary affine transformations, including 
combinations of a rotation with an enlargement or reduction, 
to be executed without introducing image defects.
Patent EP-0363970-A3 (EP)
IPC: H04N5/95
Filed: 1989-10-12
Abstract: Intermediate vertical synchronizing signals are generated 
to occur between the vertical synchronizing signals normally 
included in a conventional video signal. A first counter (19; 
31) counts clock signals which are synchronized with the hori­
zontal synchronizing signals (H s ) normally included in the 
conventional video signal to provide a count representing 
the number of clock signals which are present in one-half 
of a field interval of that conventional video signal. The 
count provided by the first counter (19; 31) during the second 
preceding field interval is temporarily stored and compared 
to a count produced by a second counter (20; 36, 40) which 
counts the clock signals from the beginning of the field in­
terval. An intermediate vertical synchronizing signal is ge­
nerated when the count of the second counter (20; 36, 40) 
is equal to the stored count.

Patent EP-0326216-A3 (EP)
Title: Counter with glitchless terminal count indication
IPC: H03K21/12
Filed: 1989-01-23
Abstract: A glitchless terminal count indication digital counter (100) 
having a clock signal (LK) 
as an input thereto is disclosed and comprises a 
state logic means (120) comprised of 
a plurality of DQ flip-flops (303,305,307,309) for 
providing a digital count with the clock signal being sent to an input 
thereof, a next state decode means (115), 
a next terminal count decode means (125) 
for providing an indication at its output that the digital output count 
will reach a terminal count at the next clock cycle, and a terminal 
count logic means (130) 
for obtaining the indication from the next terminal 
count decode means (125) 
and providing therefrom at the next clock cycle a 
glitchless terminal count indication. 
The next state decode means (115) has 
inputs (D0...D3) and outputs, with the digital 
count being an input thereto,and 
the state logic means (120) and the next 
terminal count decode means (125) being 
coupled to the output thereof. the terminal count logic means (130) is 
preferably comprised of at least one D-type flip-flop having both a 
clock signal (LK) and the next terminal count 
decode means (125) as inputs thereto, 
and logic circuitry for forcing the output terminal to indicate the 
reaching of a terminal count. When the next 
terminal count decode means (125) 
senses the penultimate count, it changes the value of its signal which 
is supplied to the flip-flop of the 
terminal count logic means (130). Thus, 
upon the next rising clock signal, the terminal count flip-flop will 
change its output and, via the logic circuitry, will force the output 
terminal of the counter to assume a terminal count value.

Title: High efficiency disk format and synchronization system
IPC: G11B27/30
Filed: 1989-04-24
Abstract: A disk drive system provides all required 
synchronization, positioning, validation, and data functions 
within each disk sector. All of these functions are 
provided within two zones, a header section and a data 
section. The header section includes a preamble, a 
synchronization character and an address field, as well as 
servo information for track following. The data section of 
each sector includes a data preamble, a data synchronization 
character, a bad sector bit map, the data and data 
redundancy information. The header section of at least one 
sector in a track includes a short DC-erase field, a 
transitionless segment which is used in synchronization. To 
synchronize a read/write head to the disk, the system first 
detects the DC-erase field. The system next searches for 
the header preamble and synchronization character. If it 
finds them within predetermined times, it then looks for a 
valid sector address to complete the synchronization. If 
the system does not detect the preamble and synchronization 
character within the predetermined times, it looks for 
another DC-erase field and continues the synchronization 
process. After the preamble and synchronization character 
are found, the desired sector is located by reading the 
addresses of the succeeding sectors.

Patent EP-0342967-A3 (EP)
Title: Electrostatic information recording medium and electrostatic information recording and reproducing method
IPC: G03G15/05
Filed: 1989-05-17
Abstract: An electrostatic information recording medium (3) 
in which a charge retaining layer (11) having high insula­
ting properties is laminated on an electrode (13) is 
disclosed, as is an electrostatic information recording/­
reproducing process wherein, while the electrostatic 
information recording medium (3) is positioned in oppo­
sition to a photosensitive member (1) in which a photo­
conductive layer (2) is laminated on a transparent electrode 
(7), the recording medium (3) is subjected to information 
exposure with the application of voltage (1 7) between 
the electrodes (13 and 7) to accumulate electrostatic 
charges thereon depending upon the dosage of said informa­
tion exposure, and the electrostatic information thus 
accumulated is reproduced by potential reading.  
     The electrostatic information recording medium 
(3) has an information density as expressed in terms 
of a high recording capacity of the order of 8 × 10⁸ 
bits/cm², and makes it possible to process information 
in a planar state so that analog or digital information 
such as characters, line pictures, images, (0.1) informa­
tion and sounds can be accumulated in the form of electro­
static charges. With this electrostatic information 
recording medium (3), it is possible to obtain information 
of high quality and resolving power because of the inform­
 
 
ation being accumulable in electrostatic charge units. 
Due to its high charge retainability, it is further poss­
ible to store information permanently. Still further, 
it is possible to make inexpensive and simple recording/­
reproducing systems, since information can be output 
by reading local potentials of electrostatic latent images 
at any time and any scanning density.
