Patent CA-2236965-A1 (CA)
Inventor: YAMADA EIJI
IPC: B60L50/16
Filed: 1996-10-28
Abstract: A power output apparatus (20) of the present invention includes a clutch motor (30), an assist motor (40), and a controller (80). The clutch motor (30) and the assist motor (40) are controlled by the controller (80), so as to enable the power output from an engine (50) to a crankshaft (56) and expressed as the product of its revolving speed and torque to be converted to the power expressed as the product of a revolving speed and a torque of a drive shaft (22) and to be output to the drive shaft (22). The engine (50) can be driven at an arbitrary driving point defined by a revolving speed and a torque, as long as the energy or power output to the crankshaft (56) is identical. A desired driving point that attains the highest possible efficiency with respect to each amount of output energy is determined in advance. In order to allow the engine (50) to be driven at the desired driving point, the controller (80) controls the clutch motor (30) and the assist motor (40) as well as the fuel injection and the throttle valve position. Such control procedures of the power output apparatus (20) enhance the energy efficiency of the whole power output apparatus (20).

Abstract: An assembly for networking a plurality of gaming machines to a central server situated at a remote location from the individual gaming machines. Each of the gaming machines includes a main processor. A plurality of peripheral controllers are provided with each controller being slaved to a selected peripheral operating device associated with the gaming machine. The peripheral controllers are each operable to transmit to the main processor data relative to the operation of each peripheral device. A distributed network architecture and communication protocol is established between the main processor and peripheral controllers which facilitate collection of data by the main controller through reduced internal wiring. A communication network consisting of an existing AC power line network within a facility operably connects each of said main processors associated with separate gaming machines in parallel to a network interface adapter/controller (NIAC) and then to network server. A first network interface adapter unit contained within each of said gaming machine outputs frequency converted signals across said existing AC power line network and the network interface adapter and control unit (NIAC) reconverts the frequency input into a digitized output for transmission to the network server.

IPC: H04M9/08
Filed: 1998-10-21
Abstract: A method of canceling echo signals in a telephone network operating in a double talk mode has been developed.          A system for implementing the method is also presented. In the invention the conventional normalized least mean square (NLMS) algorithm for echo cancellers is modified such that echo path changes continue to be tracked even after a double talk condition has been detected. The modified algorithm, known herein as a double-talk normalized least mean square (DNLMS) algorithm adaptively adjusts the convergence rate based on the power difference between the echo signal or the residual signal and the far end signal.

Abstract: L'invention concerne un principe de taxation visant à facturer entièrement la partie itinérante à l'utilisateur qui effectue un transfert d'appel vers un abonné mobile. Selon une variante, l'appel est d'abord acheminé vers le commutateur de l'abonné B, qui a transféré ses appels. Une fois établie la nécessité de transférer l'appel à un abonné mobile C, le commutateur achemine l'appel vers le centre de commutation mobile tête de ligne GMSC capable d'interroger l'enregistreur de localisation nominal de l'abonné C. Une fois établi le fichier de taxation pour l'appel, l'abonné appelé B est facturé pour la partie de communication entre le GMSC et l'abonné C, lequel n'est donc pas facturé pour les appels adressés à l'abonné B. De manière à réduire au minimum les frais d'appel liés à l'abonné B, on utilise de préférence un trajet aussi direct que possible sur la partie de communication entre le GMSC et l'abonné C.
