Patent EP-0675657-A2 (EP)
Inventor: KLINK KRISTOPHER ALLYN
IPC: H04N9/77
Filed: 1995-03-18
Abstract: A composite video input signal is delayed by a delay element (60) and the delayed composite signal is applied to luminance and chrominance inputs (40,50) of a picture processor (10) for received signals of an NTSC format. For received signals of a PAL format, the delayed composite signal is applied only to the luminance input of the picture processor and the chrominance component of the received signal is transcoded (80) to the NTSC format and applied, without passing through the composite signal delay element, to the chrominance input of the picture processor. The delay of the delay element for the composite video signal is selected to be equal to the transcoding delay whereby luminance and chrominance components of received signals of either NTSC or PAL format are delay compensated. Advantageously, the delay applied to the luminance component is constant and of the same value for signals of either format and so there is no need for switching of delay elements in the luminance path when changing from one format to the other and so undesirable switching artifacts (e.g., DC offset or transient effects) are avoided.

Abstract: The IF signal is pre-processed by a complex half-band filter and frequency-shifted by a complex mixer followed by identical low-pass filters for real and imaginary parts of the complex signal. The output is divided between a first branch for picture signal demodulation and another branch for the sound component. Each branch contains a complex mixer (FUTV;FUTT) and complex digital demodulator (DMF;DMT) with frequency- and/or phase-locked loops (AFC) for the picture component and the complex PM demodulators (FMDE1,FMDE2) of the two sound carriers. The sound carrier branches end in decimation filters (DZ4,DZ5) operating pref with factors of 2 and 11/81 for a standard sampling frequency of 32 kHz. <IMAGE>

Abstract: An electrophotographic image forming method including a toner image transfer step but eliminating an exclusive step for cleaning transfer residual toner is operated without causing ghost images and with good gradation and dot reproducibilities. In the method, the photosensitive member is exposed at an exposure intensity which is at least a minimum exposure intensity and below a maximum exposure intensity. The minimum exposure intensity is determined on a surface potential-exposure intensity characteristic curve of the photosensitive member by determining a first slope S1 of a straight line connecting a point giving a dark part potential Vd and a point giving a value of (Vd + a residual potential Vr)/2, determining a contact point between a tangent line having a slope of S1/20 and the surface potential-exposure intensity characteristic curve and determining the minimum exposure intensity as an exposure intensity at the contact point. The maximum exposure intensity is determined as 5 times a half-attenuation exposure intensity.

Abstract: Even when a plurality of cards have entered an communication area, the cards within the communication area may be accessible, and, if a data collision occurs, the order of accessing to the cards is expeditiously determined to perform an efficient communication. Each card determines a timing for returning a response block containing an ID code based on conditions directed by a read/write device and the ID code of its own. The read/write device is caused to receive the response block returned by the contactless IC card and to detect a data collision. Based on this result, the conditions are changed so that a respective response block containing an ID code is returned again, thereby concurrently processing the plurality of contactless IC cards.

Abstract: The invention is for a process to manufacture liquid crystal polymer films having balanced physical properties. The process includes feeding an oriented liquid crystal polymer material (1) into a melt region (8) formed between support membranes (3,3') passing over the surface of and through an opening between heated rolls (6,6'). The orientation of the liquid crystal polymer material is randomized and passed through the opening with the support membranes to form a laminated sandwich structure consisting of an unoriented liquid crystal polymer film between the support membranes. In another embodiment of the invention laminated sandwich structure is stretched to impart multiaxial orientation to the liquid crystal polymer film. The support membranes can be optionally removed to produce a film having a desirable surface finish.

Abstract: A development apparatus (100) for developing images, such as xerographic images, with particulate material. The apparatus includes a plate member (122) for dispersing and transporting particles such as toner particles that may be prone to agglomeration in a particle dispensing system. Movement and/or vibration of the dispersing and transporting plate member by a motor (125) serves to break up, clear and prevent particle agglomerations. Perforations, slits or mesh areas in the upper surface of the plate member can prevent oversize particles/agglomerations from passing through the system, while side walls, fins or disposing the plate member at a angle can channel the dispersion of the particles contacting the upper surface of the plate member, ensuring the required distribution of the particles.

Abstract: As a public key, a character string which can be easily reasoned by a person, e.g., a character string obtained by adding a specific character string, e.g., "?", of which code is an odd number to the end of a name, is used. A signature given to a document to be sent is encrypted by using a secret key generated from the public key, and the encrypted signature is sent together with a plaintext document. On the reception side, the encrypted signature is decrypted by using a public key obtained by adding a character string, "?" in this case, whose code is an odd number to the end of the name of the sender. The decrypted signature is compared with a signature included in the plaintext document, so that authentication can be performed. Since the public key need not be stored in an electronic dictionary file or the like, illegal authentication is not easily established by falsifying the public key in the electronic dictionary file.

Abstract: A method and system for supporting private branch exchange features over a public switched network is provided. The proprietary private branch exchange call and feature control information is separated into standard ISDN public network protocol elements and proprietary ISDN protocol elements. The interface between the originating private branch exchange and the public switched network inserts the proprietary protocol elements into a UUS service data packet for transparently transmission to the destination private branch exchange. Thus, the proprietary private branch exchange feature control information can be recovered and utilized by the destination private branch exchange, thus permitting PBX-PBX feature transparency through a switched public ISDN network.

Abstract: The invention relates to the area of register renaming and
allocation in superscalar computer systems. When a multitude
of instructions in the instruction stream reads from or
writes to a certain logical register, said logical register
will have to be represented by a multitude of physical
registers. 
     Therefore, there have to exist several physical rename
registers per logical register. The oldest one of said
rename registers defines the architected state of the
computer system, the in-order state. 
     The invention provides a method for administration of the
various register instances. Both the registers representing
the in-order state and the various rename instances are kept
in one common circular buffer. There exist two pointers per
logical register: The first one, the in-order pointer,
points to the register that represents the in-order state,
the second one, the rename pointer, points to the most
recent rename instance.
