Title: Technique for reading bar codes
IPC: G06K7/00
Filed: 1989-05-22
Abstract: A technique for reading a bar code representative of 
message information is stored electronically in bit-map form. 
The bit map is obtained by optically scanning a document 
carrying non-bar code information also to convert pixel 
information into bit information. A row is identified in the 
bit map which is the most likely one to pass through an area in 
the bit map containing bar code information. The data stored 
in the bit map is compared with assigned data corresponding to 
designated bar code components. Once such a row is identified, 
processing of rows above and below it in the bit map reveals 
whether rows more likely to agree with the coded message 
information can be found. Initially, a fast processing mode is 
selected involving processing of only a few rows to maximize 
processing speed in case acceptable data can be found. If 
acceptable bar code data is not found, then the processing is 
switched into a slow processing mode which involves processing 
of a greater number of rows. Once a row likely to contain the 
bar code data of interest is identified, the information it 
contains is converted into signals which are used for 
converting the coded bar code data into the message represented 
thereby.

IPC: A61P7/08
Filed: 1989-08-11
Abstract: Agents for inhibiting adsorption of proteins on 
the liposome surface and liposomes which are agglutination-­
free by binding said inhibiting agent on the surface are 
disclosed. The above-mentioned inhibiting agents comprise a 
hydrophobic moiety and a hydrophilic macromolecular chain 
moiety. Adsorption of plasma proteins on the liposomes is 
inhibited due to the hydrophilic moiety exposed on the 
liposome surface with a result that agglutination of the 
liposomes in plasma is prevented. Therefore, there is no 
danger of embolism in blood vessels inhibiting blood flow 
when the liposomes are introduced into the living body. 
Accordingly, the liposomes are especially highly useful as 
artificial erythrocytes for which a large dose of liposomes 
is needed for administration.  
     Moreover, when liposomes are introduced into the 
living body, antibody protein (immunoglobulin) to the lipo­
some which is an antigen will be adsorbed on the liposome to 
produce foreign body recognition in the phagocytes (macro­
phage) with a result that the liposome will be included in 
the macrophage and disappear within a short period of time. 
Thus, inhibition of the protein adsorption on liposome can 
delay disappearance of the liposome in plasma.  
     In addition, a method for preparing the above-­
described liposomes is disclosed.

Title: Method for the transmission of 1544 and/or 6312 kbit/s signals over 2048 and/or 8448 kbit/s links in the synchronous digital multiplex hierarchy
IPC: H04J3/16
Filed: 1990-11-26
Abstract: A method for transmitting 1544 or 6312-kbit/s signals via a 2048 or 8448-kbit/s link is not known in the synchronous digital multiplex hierarchy and is to be specified. A 1544-kbit/s signal is inserted in the direction of multiplexing, using a gapped 2048-kHz clock (LT11) into a container C-111 which is completed by means of a path overhead V511 to form a virtual container VC-1111. This is transmitted via a 2048-kbit/s link (L11) with a link container (S-1111) to which a header (OH11) and pointer bytes V111 to V411 are allocated for the transmission. After adding stuffing bytes (FS11), the 1544-kbit/s signal can be fed into a subsystem unit TU-121. In the direction of demultiplexing, stuffing bytes (FS12) must be removed from a subsystem unit TU-122 and pointer bytes V112 to V412 must be inserted with the aid of a gapped 2048-kHz clock (LT12) and a header (OH12) must be inserted with the aid of a 2048-kHz clock (T12) for the transmission via a 2048-kbit/s link (L12). After the transmission, the header (OH12), the pointer bytes V112 to V412 and a path overhead V512 are removed so that the 1544-kbit/s signal can be taken from a container C-112. A 6312-kbit/s signal is transmitted correspondingly. <IMAGE>

Patent EP-0409326-A3 (EP)
Title: Rotary speed sensor
IPC: G01P3/488
Filed: 1990-07-12
Abstract: A rotary speed sensor system uses a permanent 
magnet (14) and a Hall cell (16) sensitive to the changing 
tangential component of magnetic field caused by the 
interrupted surface profile of a rotary element (10). In 
order to avoid anomalies caused by the variation of the 
base value of the tangential component of magnetic field, 
the output of a differential amplifier (OP1) fed by the 
Hall cell (16) is connected to a voltage averaging means 
(OP2, R5, C1) which stores the average voltage on a single 
capacitor (C1). The output of the differential amplifier 
(OP1) and the voltage across the capacitor (C1) are 
respectively coupled to the differential inputs of a 
Schmitt trigger (19) exhibiting hysteresis. The Schmitt 
trigger (19) thereby establishes operate and release points 
relative to the average voltage signal. The voltage 
averager (OP2, R5 C1) is a non-linear circuit in which the 
voltage across the capacitor (C1) is fed back to the 
negative input of an operational amplifier (OP2). A power-­
up circuit (OP5, R10, D1, Q2) is also provided for rapidly 
charging the capacitor (C1) initially to approximately the 
average voltage.

Title: Cordless telecommunications apparatus
IPC: H04M1/733
Filed: 1991-01-23
Abstract: Telecommunications apparatus is provided for use in the cordless telephone environment where a number of handsets are arranged to communicate with a plurality of base stations. When a handset indicates that it wants to communicate with a base station it may be recognised by a base station which is not necessarily the nearest one for best reception. The base station, before setting up a link, compares the received signal strength with a predetermined stored threshold level. If the signal strength is above the level, the base station immediately attempts to set up a link. If it is below the level, the identity of the handset is stored and if the same base station receives a subsequent request from the same handset it then attempts to set up a link with that handset. <IMAGE>

Patent EP-0571892-A3 (EP)
IPC: G06K7/10
Filed: 1993-05-19
Abstract: The camera system (10,100) of the present invention simultaneously searches for a number of differing optical acquisition targets (44). Upon detecting an acquisition target (44) it decodes according to corresponding differing decoding algorithms. To facilitate this operation there is a system bus (170) as well as a dedicated data bus (172) for applying a scan signal of an optical scanning device (154) to differing detection circuitry. This system may decode, for example, both bar codes and concentric rings. The scan signal is constantly adjusted according to both a dark reference for correcting offset and a white reference for correcting gain. The gain is also corrected according to the scanning rate as well as the amount of illumination present. A measure of this illumination may be applied directly to the optical scanning device (154) by way of a fiber optic cable (402) which transmits light from the illumination source (15). When detecting concentric rings the system of the present invention uses stored templates which represent a number of transformations of the target (44), for example, a number of magnifications. When the transformation of a target (44) is determined, the corresponding stored template is correlated with the scan signal from the optical scanning device (154). To detect concentric rings the scan signal is applied to interleaving circuitry (180) which correlates more than one scan at a time to provide constant throughput even though the stages of the detector operate at different speeds. Optical calibration is eliminated by fixed optics wherein all optical elements are rigidly mounted at very close tolerances. The illumination source (15) is disposed on one focus (22) of an ellipse (18) wherein the other focus (24) is disposed at the maximum scanning distance and the reflector (14) is formed to define the illumination ellipse (18) to maximize the light applied to the object (42). The various heat producing elements are disposed in sealed compartments (40a,b,c) which are cooled by forced air which is circulated through a heat exchanger. A real time focusing system is provided wherein the distance from the scanning device to an opposing surface is constantly monitored and the system is constantly focused according to the distance. <IMAGE>
