Abstract: A concrete circuit configuration is proposed of a multiplex transmitter for loading a standard ATM cell with multiplexed micro-frames which are each shorter than the standard ATM cell. The input micro-frames are delivered to a distributor 504 in the input order through an interface 503. The distributor 504 distributes the input micro-frames using distributing information input. The distributing information accords with the service condition of each connection or micro-frame. An extracting circuit 506 selects buffers in accordance with predetermined buffer selection logic. A cell cancellation monitor circuit 508 relinquishes micro- frames exceeding cell tolerable time periods T2-1 -  T2-m. A multiplexing processor 507 transfers the cell or a idle cell to a sender 511 in accordance with the cell transfer timing of the sender 511.

Abstract: A digital waveform generator complies with different vertical blanking interval (VBI) standards, and is inserted into VBI portions of a digital component video signal. A buffer receives symbols carrying VBI data for a particular VBI service according to a user data syntax, which identifies a television line into which the VBI data is to be inserted. A symbol processor is responsive to information provided by the syntax. This information indicates the number of pixels represented per symbol, a symbol transition time, and the number of symbols carrying data to be inserted into the VBI portion. The symbol processor provides the VBI data in a format according to the particular VBI service. A timing circuit is responsive to a start time provided by the syntax for inserting the VBI data. A level control circuit adjusts the level of the VBI data prior to insertion into the VBI portion in response amplitude values provided by the syntax.

Title: Method and system for providing answer supervision in a switched telephone network
Inventor: O'BRIEN WILLIAM G
IPC: H04Q3/00
Filed: 1998-02-06
Granted: 2000-12-05
Abstract: A method and system for providing answer supervisuon in a switched telephone network are described. The method involves monitoring signaling links in a common channel signaling system to track call progress. If a called number is determined to be suspect with respect to providing call answer indications, the system may route calls to monitored facilities which measure the commencement of payload traffic. When payload traffic is detected, a call answer message can be sent through the signaling network to initiate billing, or call release messages may be sent in each direction to cancel the call. Both inter-network and intra-network calls coin be monitored to provide answer supervision and ensure that toll calls are properly billed in accordance with actual toll facility usage.

Abstract: Compositions de liant inorganique durcissant à froid utilisées pour lier de la matière particulaire et procédés de durcissement de ces liants inorganiques. Les compositions de liant inorganique sont formées de constituants silicate et phosphate. Les compositions durcissant à froid renferment également un catalyseur de durcissement tel qu'un catalyseur sélectionné dans le groupe formé par les carbonates aliphatiques, les carbonates d'alkylène cyclique, les esters d'acide carboxylique aliphatique, les esters d'acide carboxylique cyclique, les esters de phosphate et les mélanges de ces derniers. La composition produit un liant présentant les propriétés de résistance recherchées d'un liant au silicate associées aux propriétés de décomposition dans l'eau d'un liant au phosphate. Par conséquent, par rapport à un liant entièrement au silicate, cette invention se caractérise par un effondrement mécanique amélioré et une meilleure aptitude au débourrage dans l'eau. De même par rapport à un liant entièrement au phosphate cette invention se caractérise par une meilleure résistance à chaud c'est-à-dire que les noyaux et les moules de fonderie ne se ramollissent pas à des températures élevées. Les procédés de préparation et d'utilisation de ces compositions de liant ainsi que les produits résultants sont particulièrement intéressants pour l'art de la fonderie.

Title: Pll circuit for digital display apparatus
Inventor: NISHIMURA EIZO
IPC: G09G3/20
Filed: 1996-11-20
Granted: 2002-05-28
Abstract: A PLL circuit is provided with a lock/unlock detecting circuit which detects  the locked or unlocked state of the PLL circuit by comparing the phases of a  horizontal synchronizing signal and a comparing signal with each other and a n internal synchronizing signal generating circuit which outputs the comparing  signal as an internal synchronizing signal when the locked state is detected  or outputs the horizontal synchronizing signal as the internal synchronizing  signal when the unlocked state is detected. Another mode of a PLL circuit is  provided with a skew detecting circuit which resets a frequency dividing circuit upon detecting a skew which is deviated from a normal period in an external synchronizing signal, generates a dummy pulse upon detecting that n o skew occurs in the external synchronizing signal in the normal period, and generates a reference signal in combination of the dummy pulse with the external synchronizing signal. When the skew detecting circuit detects a ske w, the circuit also resets a phase comparator circuit. A digital display device  having such a PLL circuit prevents distortion of the picture when the PLL circuit is in an unlocked state or a skew occurs.
