Title: Personalized information service system
Inventor: BACKAUS MARJORIE SUSAN
IPC: H04M3/42
Filed: 1994-07-18
Granted: 1998-12-15
Abstract: A high-speed information service system is provided which uses a unique identifier received during call setup to retrieve automatically a personalized profile for an information service subscriber. The identifier uniquely identifies the subscriber, thereby allowing the information retrieval process to begin immediately after the call is setup. The system utilizes Integrated Services Digital Networks (ISDN) signaling and temporary, "out-of-band" signaling to improve information retrieval capability. ISDN signaling permits electronic addressing of information requested by the subscriber, thereby eliminating the delays which accompany DTMF signal processing. Communications between an information service provider and an individual information source are conducted using out-of-band signaling. That is, call setup and information request are processed using a channel other than the channel which carries data between the information service provider, the information source and the subscriber.

Title: A cdma communications method and system
Inventor: ADACHI FUMIYUKI
IPC: H04W76/00
Filed: 1994-11-02
Granted: 2002-03-26
Abstract: A CDMA communications method capable of multiplex transmission of data over a wide range from a low rate to high rate such as image data without a considerable increase in a circuit scale. A fundamental transmission rate is determined, for example, at 32 kbps, a rate higher than 8 kbps conventionally used. The data whose transmission rate is equal to the fundamental transmission rate is transmitted in frames including no vacant portion. Data whose transmission rate is lower than the fundamental transmission rate (16 kbps, for example) are transmitted in frames including vacant portions. The vacant portions are not transmitted. This makes it possible to receive data through other channels during a time period associated with the vacant portions. Data of a higher transmission rate, 128 kbps, for example, can be multiplexed and transmitted through four channels using different spreading codes.

Title: Dynamic queue length thresholds in a shared memory atm switch
Inventor: CHOUDHURY ABHIJIT KUMAR
IPC: H04L12/56
Filed: 1995-08-22
Granted: 2001-08-07
Abstract: A dynamic threshold system and method is disclosed for allocating memory among different output queues in a shared-memory ATM switch. The maximum permissible length for any individual queue at any instant of time is a function of the unused buffering in the switch. The dynamic threshold system and method deliberately reserves a small amount of buffer space, not allocating it to any currently active output queue, but attempts to equally share the remaining buffer space among the currently active output queues. The dynamic threshold system and method improve fairness and switch efficiency by guaranteeing access to the buffer space for all output queues, and by preventing any single output queue from monopolizing the memory at the expense of the others. The dynamic threshold system and method adapt to uncertain or changing load conditions. The packet losses that occur with dynamic thresholds tend to be clustered at a few offending queues, which is desirable in ATM systems, since it results in fewer messages being disturbed at higher protocol layers and, hence, fewer message retransmissions.      The dynamic threshold system and method are also extendable to handle traffic with multiple space priorities.

Abstract: A pair of travel rails 46 each having an upper surface and a lower surface are laid to extend from on the land 44 into the water 45. Main tires 12 are rotatably disposed on opposite sides of a vehicle body 1, so that they are located between the upper and lower surfaces of the travel rails 46, and so that they abut against the lower surfaces of the travel rails 46 during traveling of the vehicle body on the land. Auxiliary tires 13 are disposed on upper portions of the main tires 12 to abut against the main tires 12. The auxiliary tires 13 are adapted to abut against the upper portions of the travel rails 46 under influence of the buoyancy of the vehicle body 1 during traveling of the vehicle body in the water. Thus, the travel vehicle body 1 can continuously travel on the land and in the water by rotatively driving the main tires 12 to move the travel vehicle body 1 along the travel rails 46.

Patent CA-2188369-C (CA)

Granted: 2005-01-11
Abstract: Described is a method and an arrangement for classifying speech on the basis of wavelet transformation for low rate speech coding methods. The method or arrangement as a robust classifier of speech signals for the signal-matched control of speech coding methods for lowering the bit rate at a constant speech quality, or to increase the quality for an identical bit rate is characterized in that after segmentation of the speech signal a wavelet transformation is calculated for each frame, from which--with the help of an adaptive threshold--a set of parameters is determined, this set of parameters controlling a status model that divides the frame into shorter subframes and then assigns each of these subframes into one of several classes that are typical for speech coding. The speech signal is classified on the basis of the wavelet transformation for each time frame. Thus, it is possible to achieve a high level of resolution in the time range (localisation of pulses) and in the frequency range (good average values). This method and the classifier are thus suitable, in particular, for controlling or selecting code books in a low rate speech coder. In addition, that are not sensitive to background noise, and display a low level of complexity.

Les moyens de retenue empêchent la chute ou le retour vers l'arrière en position fermée du panneau après son ouverture. Lesdits moyens de retenue sont conçus de telle façon que le panneau peut passer depuis sa première position ouverte à une deuxième position ouverte sous l'effet d'une deuxième force prédéterminée exercée sur le couvercle. Ceci empêche la boîte de basculer quand une force trop importante est exercée sur le couvercle ou que celui-ci est arraché accidentellement de la boîte.

Title: Communication system and method using two-way paging to provide call control
Inventor: FOLADARE MARK JEFFREY
IPC: H04W88/02
Filed: 1996-11-19
Granted: 2001-01-16
Abstract: A system and method of using two-way paging to establish communications with a mobile party having a Personal Telephone Number.  The mobile party is equipped with a two-way pager which the party may use to provide call control. The pager is periodically queried by a network and/or paging service to determine whether or not the pager is reachable.  If the pager becomes unreachable, and thereafter a call is placed to the party's Personal Telephone Number, the network routes the call to a default station.  If the pager is reachable, any one of a number of alternative call routing procedures may be invoked including: registration type routing, call-by-call routing, revertive calling, call examination routing, and subsequent routing. In one possible embodiment, a Customer Routing Point is used to store the pager status along with other call routing information, and a Network Control Point is used to carry out the appropriate routing procedure.  Other possible embodiments include: using an adjunct to perform the functions of the Customer Routing Point and Network Control Point; and combining an adjunct with a Customer Routing Point and Network Control Point.

Abstract: A radially expandable stent-graft and method of making the same, including at least one stent member encapsulated between at least two longitudinally expanded polytetrafluoroethylene (ePTFE) coverings. The at least one stent member (22) has openings through wall surfaces of the stent to permit radial expansion. The at least two longitudinally expanded ePTFE coverings (24, 26) are circumferentially applied over the at least one stent member in their unsintered state, and sintered during application of a circumferential pressure to bond the ePTFE around and through the wall surfaces of the stent (22). The sintered ePTFE forms a substantially continuous, monolithic and integral encapsulation of the at least one stent. Upon radial expansion of the stent graft (10), the stent and the ePTFE node-fibril microstructure radially deform. Radial deformation of the ePTFE encapsulation results in nodal elongation in the axis of radial expansion. After radial expansion of the stent-graft (10), a substantial bonded area remains intact and maintains the encapsulation of the stent in vivo.
