Patent EP-0310431-A3 (EP)
Title: Method and apparatus for providing enhanced tissue fragmentation and/or hemostatis
IPC: A61B17/00
Filed: 1988-09-30
Abstract: An apparatus having a vibratable tip (22) for ultrasonically disintegrating tissue in a surgical procedure and for aspirating the disintegrated tissue and fluid away from the surgical site (12) through an opening (24) in the tip. A connection (42) to the electrosurgical unit provides for delivery of RF cutting current, RF coagulating current or a blend thereof to the tip so that electrosurgical procedures can be conducted separately or simultaneously with ultrasonic aspiration through the tip. It thus is now possible, for example, to electrocauterize simultaneously with ultrasonic fragmentation with a single handheld surgical device. The simultaneous delivery of ultrasonic vibrations and RF current to the tip also has been found to increase the tissue fragementation rate.

Title: Mechanism for adjusting the stitch density in circular knitting machines
IPC: D04B9/02
Filed: 1988-06-23
Abstract: The mechanism allows the stitch density to be varied 
simultaneously with the knitting process. It is achieved 
by way of a single stationary main control (28) with which 
rotating controls (54), one for each cam set, successively 
align. Control (28) is provided with a motor (30) 
regulated by a controller, a first sliding member (38) and 
a proximity detector (52) and each rotating control (54) 
comprises a second vertical sliding member (56) attached 
to the stitch cam (20). According to a programme, for each 
cam set, the motor (30) drives the sliding member (38) and 
the movement of the latter is applied to the second 
sliding member (56) through transmission means (49, 62, 
60, 68).

Filed: 1989-01-18
Abstract: Methods for producing a secreted receptor analogs 
and biologically active peptide dimers are disclosed. The 
methods for producing secreted receptor analogs and biologi­
cally active peptide dimers utilize a DNA sequence encoding

biological activity joined to a dimerizing protein. The 
receptor analog includes a ligand-binding domain. Polypep­
tides comprising essentially the extracellular domain of a 
human PDGF receptor fused to dimerizing proteins, the 
portion being capable of binding human PDGF or an isoform 
thereof, are also disclosed. The polypeptides may be used 
within methods for determining the presence of and for puri­
fying human PDGF or isoforms thereof. Pharmaceutical and 
diagnostic compositions utilizing the polypeptides are also 
disclosed.

Title: Formation of metallic interconnects by grit blasting
IPC: B24C3/32
Filed: 1989-05-13
Abstract: This invention relates to a ceramic module and to 
methods for forming protruding, upstanding electrically 
conducting pins by the selective abrasion of a surface 
(18) of a multilayered ceramic module (10). An abrasive 
blasting device (40) is disposed adjacent to the surface 
(18) for directing a stream of abrasive particles (42) 
against the surface. The particles (42) strike both 
metallic conductors (20) and (22) and also the ceramic 
material of the layer (14). Inasmuch as the ceramic 
material is relatively hard and brittle as compared to 
the ductile metallic conductors the abrasive particles 
(42) abrade away the ceramic layer (14) at a faster 
rate than the ductile metallic material of the con­
ductors (20) and (22). The abrasive particles (42) may 
be comprised of any suitable abrasive, such as Al₂O₃, 
SiC or WC. The module may be rotated beneath a nozzle 
of the grit blasting device, the nozzle being linearly 
translated above the surface being abraded.

Title: Method for downloading a scrambled television signal and receiver therefor
IPC: H04N7/16
Filed: 1989-04-24
Abstract: A scrambled television signal is downloaded for recording 
on a video cassette recorder (VCR) (10) by receiving a 
scrambled signal via an antenna (2) and a tuner (4). A 
descrambler (6) determines whether or not the signal contains 
a predetermined data code and if the data code is present 
enables operation of the descrambler (6) as well as generating 
an "access granted logic signal" to enable operation of a 
microprocessor/logic control circuit (8). The 
microprocessor/logic control circuit generates control signals 
for the VCR (10) and these may be via an infra-red control 
unit (18). The control signals cause the VCR (10) to record 
the descrambled output of the descrambler (6).

Title: An interactive dynamic range adjustment system for printing digital images
IPC: G06T5/00
Filed: 1989-12-20
Abstract: An interactive dynamic range adjustment 
method for printing digital images, and an 
implementation system, are disclosed. The method is 
based on experimental findings about visual 
photoreceptor adaption and human visual contrast 
sensitivity. The system adjusts the contrast of the 
low-frequency component only of the image, preserving 
(or if one wishes, enhancing) the high-frequency image 
component in its contrast. The adjustment is 
controlled by a mapping curve which the user 
manipulates interactively. The simulated optical 
print image (44) and the dynamic range adjusted image (44') are 
displayed side by side on a monitor screen (30) so that the 
user can make proper selection of parameters to 
achieve the desired effect. For many images, the 
system automatically computes good parameters and no 
further adjustment is needed.

In the fork head (23.1), a transverse pin (24) is mounted, which extends through the slot (22) and in this manner holds the two last parts (11, 12) together. A two- part receiving plate (30.1, 30.2) serves to fix the last (10) in the working stations of the transfer installation. In order to guarantee a secure and lasting adjustment of the receiving plate (30.1, 30.2) in a last made of plastic also, there is in each case made below and parallel to said plate in the last parts (11, 12) a bore (31.1, 31.2). These bores (31.1, 31.2) each receive a metal part (32.1, 32.2) which is provided with threaded bores (34). The fastening screws (33.1, 33.2) of the receiving plate (30.1, 30.2) engage in these threaded bores (34).

Title: Signature verification method
IPC: G06T7/00
Filed: 1990-02-13
Abstract: A signature verification method which a signer is checked whether an identical person or not by comparing a true signature preliminary registered to a signature electrically inputted by a true signer. To eliminate errors on time and space particular to the input pattern, dynamic programming matching is performed on the input pattern in this verification system. In order to distinguish a true signature from forgeries, a pattern matching is executed by obtaining divergencies between the information of the input pattern and that of the registered pattern distributed on a two-dimensional map composed of two major elements; shape axis and movement axis. Said two-dimensional map includes a genuine signature area, a false signature area, a forgery signature area and a boundary signature area.
