Filed: 2003-07-24
Abstract: La présente invention concerne un procédé, une fonction de commande d'état d'appel par proxy (P-CSCF) et un réseau de données par paquet permettant de créer des filtres de paquet destinés au mappage de flux de données dans la fonction P-CSCF et permettant leur transmission à un noeud d'accès de données par paquet (PDAN) tel qu'un noeud de service de données par paquet (PDSN) d'un réseau CDMA 2000. Une session de données par paquet est établie entre un terminal tel qu'une station mobile (MS) et un noeud correspondant (CN) au moyen d'un protocole de début de session (SIP). La fonction P-CSCF recueille des informations relatives aux adresses IP et au numéros de port des parties, aux flux de données de la session de données ainsi qu'aux instances de service entre le terminal et le noeud PDAN. A partir de ces informations, la fonction P-CSCF crée un filtre destiné à mapper chaque flux de données du noeud CN aux instances de service disponibles. Le filtre est envoyé au noeud PDAN, lequel installe et utilise ce filtre et effectue l'acheminement approprié des flux de données entrants.

Patent CA-2001277-A1 (CA)
IPC: H04B3/23
Filed: 1989-10-24
Abstract: In a hands free communications terminal apparatus, a loudspeaker and a microphone are permitted to be simultaneously active.  A controller monitors signals in transmit and receive paths to direct operations of transversal filters to provide two echo canceler functions, one for the microphone and one for a telephone line so that most unwanted echo and feedback is removed, to prevent the howling and squealing sounds that commonly occur when the loudspeaker and the microphone are both active.  Remaining echoes are removed by voice switching of loss between transmit and receive paths, wherein the amount of loss is determined in response characteristics of the telephone line and the operating environment of the terminal apparatus.
Patent CA-2001712-A1 (CA)
Inventor: KOS JOSEPH F
IPC: B60W20/00
Filed: 1989-10-27
Abstract: This invention is a hybrid engine employing a reciprocating  piston  in  conjunction  with  an electromagnetic transducer for control and power output.   The transducer is  essentially a specialized linear motor/ generator.  The piston is rigidly connected by means of a rod to a permanent magnet (or equivalent).  The piston-rod-magnet unit is constrained by bearings to move translationally along one axis.  The magnet can move linearly into and out of the yoke of the magnetic transducer to generate an electric current in the windings of the yoke.          At the same time computer control of the effective impendences of these windings as well as computer controlled currents  (provided by  an  electric  storage battery or electrical energy storage indicator) flowing through some (or all)  of these windings control the motion of the magnet and hence of the piston.  Computer control is also exercised over other devices to regulate ignition timing, fuel injection, air intake, valve motion, etc.  The power output may be used to drive A.C.,  D.C.  or A.C./D.C. motors or it may be wholly or partially rectified to charge batteries and/or power A.C./D.C. or D.C. motors or to power other devices.

Abstract: A method and system for the dispatch of resources to remote sites in response to alarm signals. A preferred embodiment particularly relates to a system for the dispatch of field service engineers to a plurality of remote sites in response to fault conditions detected in systems for the storage and retrieval of voice signals. A processor accesses a database of field service engineers designated to provide services to particular remote sites in response to alarm signals received from those sites and then attempts to establish a telephone connection with the field service engineer. Once communication is established, the processor provides the field service engineer with information by means of synthetic voice messages. In a preferred embodiment of the subject invention, the system may also execute remote diagnostic programs and where the results of the diagnostic programs are not within predetermined limits, the system will again attempt to contact a field service engineer.

Title: Message generating communication apparatus having a message preamble format allowing parts of certain messages to be ignored
Inventor: AGGERS JOHN R
IPC: H04J3/16
Filed: 1989-12-18
Abstract: ABSTRACT OF THE DISCLOSURE        A communication system has a first node which transmits on a data bus messages each having a preamble having a predetermined format including a message type and the message length, and a plurality of second nodes receiving messages from the data bus and including elements which can determine that the preamble in each message has the predetermined format.  The preamble is particularly useful for allowing the second nodes to quickly detecting messages not directed to those nodes of which the elements form a part, allowing the node to ignore the remainder of the message.  This allows the individual nodes to exclude the message interpretation for detecting messages directed to them, from their processing tasks thereby improving the effective processing speed of the network.

IPC: A63F9/24
Filed: 1990-03-29
Abstract: An electronic baseball game is presented which permits the human operators to input individualized attributes or statistical information relative to the batter, runner and pitcher based on real or fictionalized baseball players.  In a preferred embodiment, this statistical information is encoded as a bar code printed on a sticker.  In turn, the sticker is placed on the edge of a card, preferably a standard baseball card.  The bar code contains information as to the batting average, right or left handed batting and pitching, pitching speed, running speed and hitting power.  The statistical information on the bar coded card is then entered into the electronic baseball game by sliding the card through a slot containing a conventional photo optical bar code reader.  The statistical information is then used by the computer program in the game to regulate and interact with the playing activity of the human players.  Thus, in accordance with the present invention, a baseball card can act as a programmable means to enter supplementary information into an electronic baseball game to thereby effect the gameplay.  The electronic baseball game of the present invention also includes a scoreboard, liquid crystal display (LCD) playing field and a plurality of switches which allow the human player to select a desired type of pitch (e.g. change-up, off-speed or fast ball); to steal a base or pick-off a base runner; to send in a relief pitcher; to bunt or execute a double play and of course, to initiate the actual pitching and batting actions.

Abstract: CONTROL METHOD OF CLUTCH-TO-CLUTCH POWERED DOWNSHIFT IN AN AUTOMATIC TRANSMISSION            Abstract of the Disclosure In an automatic transmission, clutch-to-clutch powered downshifting is controlled by filling the on-coming clutch at a low pressure while ramping down the off-going clutch pressure until turbine speed is pulled up due to off-going clutch slippage, and then increasing the off-going pressure stepwise to compensate the change from static to dynamic coefficients of friction.  Then the on-coming pressure is gradually ramped up and a closed-loop profile control period starts wherein the slip of the on-coming clutch is measured and controlled to a slip profile by controlling the off-going clutch pressure.  When synchronization of the on-coming clutch is first detected, a closed-loop sync control period starts wherein the off-going pressure is controlled to minimize the slip and the on-coming pressure is ramped up at a steeper rate to begin clutch engagement during the sync control period.
