IPC: H04N7/30
Filed: 1996-10-18
Abstract: A video signal encoding/decoding system reduces ringing noise by using a post-filter which performs anisotropic diffusion on decoded data. The exemplary system uses an encoding/decoding technique such as that developed by the Moving Picture Experts Group (MPEG). The post-filter processes individual blocks of pixels, assigning an individual edge significance threshold to each block. Noise removal occurs if the edge strength is below the threshold and is inhibited if the edge strength is above the threshold.

Abstract: In an ink jet type head assembly, a plurality of elongate ejection electrodes are formed on a base. An ink chamber has an opening facing one end of the ejection electrodes, and stores liquid ink containing charged toner particles on the base. One end of each ejection electrode is positioned on the base. An ink meniscus is formed between the end of the base where the above end of the ejection electrode is positioned and the opening of the ink chamber. An opposite electrode faces the ends of the ejection electrodes with the intermediary of a recording medium. The base is inclined about its end toward the ink chamber by a preselected angle with respect to a plane perpendicular to the lengthwise direction of the opposite electrode.

Abstract: In a process for the classification of an article such as a banknote described by of a k-dimensional feature vector (AGF) which is prepared by a preliminary processing system (7), a test specimen is either assigned to one of n target classes or classified as a counterfeit. For the n target classes n recognition units (15.1 to 15.n) are used, exactly one of the n target classes being recognisable by one recognition unit (15.j) using a respective feature vector (AGF j ) prepared for that class. A recognised target class is transmitted by an output unit (14) to a service system (11). There are assigned to a target class in a learning phase several k-dimensional target vectors which are compared with the feature vector during the classification. The recognition unit (15.j) is advantageously a neural network, one neuron comparing the feature vector (AGF j ) with one of the target vectors.

Abstract: A searching and block access method on a digitally recorded tape. The method enables a digitally recorded tape (65) to be randomly positioned to access a specific requested data block. This method does not rely on scanning the information recorded on the tape to locate a requested data block. The tape is shuttled at high speeds to randomly requested locations. Tape positioning and control is accomplished by profiling the motion required to position the tape at the requested block relative to any current tape position. A tape directory of contents and tape position is recorded on the tape and cached within the drive controller (68). The cached version of the tape directory is used for random accesses. The random access ability enables the tape implementation to perform disk storage emulation.

Abstract: Herein disclosed are a method and an apparatus for supplying an electrical energy to a pair of discharge electrodes (13a and 13b) spaced apart from each other to cause an electric discharge in a gap between the discharge electrodes (13a and 13b). There are firstly provided an alternating voltage generator (11) for generating, as the electrical energy, an alternating voltage having a frequency, and a capacitor (12) connected to the discharge electrodes (13a and 13b) in series. The alternating voltage generator (11) has a series resonant frequency. The alternating voltage of the alternating voltage generator (11) is applied to the discharge electrodes (13a and 13b) through the capacitor (12). The frequency of the alternating voltage is set approximately to the series resonant frequency of the alternating voltage generator (11) to cause a dielectric breakdown in and allow an electric discharge current to flow through the gap between the discharge electrodes (13a and 13b). Alternatively, the frequency of the alternating voltage may be approximated to the series resonant frequency of the alternating voltage generator (11), for example, from a frequency higher than the series resonant frequency.

Abstract: A method of attenuating an unwanted electric field radiation A2 caused by an electrostatic induction on an internal conductive coating 2 of a cathode ray tube 6 with a pulse voltage A which has a horizontal deflection period and is generated by a deflection circuit 4.

Abstract: The invention provides a trusted agent for anonymous
voice communication using telephones. The trusted agent
includes an access network communications unit, a memory
device and a voice bridge processor coupled to the memory
device and the access network communications unit. The voice
bridge processor receives information through the access
network communications unit from at least one user and
connects the at least one user to a telephone network for
anonymous voice communication. The voice bridge processor
displays to the at least one user a display panel prompting
the at least one user to enter a telephone number and an
identification. The voice bridge processor searches the
memory device for an entry corresponding to the
identification entered by the at least one user. If the
entry corresponding to the identification is found, then the
voice bridge processor connects the at least one user with
another user identified with the identification entered by
the at least one user. If the identification entered by the
at least one user is not found, the voice bridge processor
creates an entry in the memory device corresponding to the at

Abstract: A scheme for depositing a private key used in the RSA
cryptosystem which is capable of maintaining the private
key more safely, without requiring a user to always carry
around a storage medium. In this scheme, a private key of a
user is divided into a first partial private key and a
second partial private key at a user's entity, where the
first partial private key is set to be maintained at the
user's entity, while the second partial private key is
deposited from the user's entity to the other entity. Then,
the second partial private key is delivered from the other
entity to the user's entity in response to a request from
the user's entity, and the first partial private key
maintained at the user's entity and the second partial
private key delivered from the other entity are composed so
as to obtain the private key to be used in a processing
according to the RSA cryptosystem at the user's entity.
This scheme can be generalized to a case of dividing the
private key into a plurality of partial private keys.

Abstract: A sheet feeder, or a printer incorporating the sheet feeder, has
separation pads for separating a sheet to be fed by sheet feed rollers from the
next sheet and a roller spring which produce urging force smaller than that
produced by a spring of the separation pad. Idle rollers are brought into
contact with the separation pads by means of the roller spring, thereby
preventing the lowering of the next sheet. A sheet reset lever is pivoted so as
to return the next sheet to a hopper. As a result, the sheet sheets stacked on
the hopper in an inclined state is fed one by one through use of a separation pad
method without increasing force for driving rollers and a back tension.

Abstract: A method for replacing parts of a digitally coded
picture (11) is proposed. The digitally coded picture
(11) may correspond to a sub-picture which is displayed
on the screen of a television set (10). In the method,
each line of the picture (11) is run length-coded. The
replaceable parts of a line of the picture are run
length-coded separately. The part which replaces the
replaceable, original part of a line of the picture (11)
is run length-coded in such a way that it has the same
number of data units (data bytes) as the original part of
this line of the picture (11). The replacement of the
data for the run length coding words is carried out in a
memory device. The replacement is possible in a
simple manner by virtue of the fact that the original
part of a line of the picture and the new part of the
line of the picture have the same number of data units.
Moreover, a device for carrying out the method is also
proposed.

As such, variations in the distance between the wafer and the electrodes due to variations in dielectric thickness, wafer backside roughness, chuck surface roughness, chuck surface conductivity or other physical variations that may cause changes in the electrostatic force are balanced by having the spacing mask connected to the centre tap of the power supply.
