Title: Apparatus and method for reducing speech recognition vocabulary perplexity and dynamically selecting acoustic models
Inventor: WONG CHI
IPC: H04M3/42
Filed: 1997-01-09
Abstract: A method of reducing the perplexity of a speech recognition vocabulary and dynamically selecting speech recognition acoustic model sets used in a simulated telephone operator apparatus. The directory of users of the telephone network is subdivided into subsets wherein each subset contains the names of users within a certain location or exchange. A speech recognition vocabulary database is compiled for each subset and the appropriate database is loaded into the speech recognition apparatus in response to a requested call to the location covered by the subset. Furthermore, a site-specific acoustic model set is dynamically loaded according to the location of a calling party. An apparatus for carrying out the method is also discussed.

Title: Drying of atomized metal powder
Inventor: LARSSON RUTGER
IPC: F26B21/14
Filed: 1997-04-18
Abstract: Metal powder, particularly iron/steel powder with low oxygen content, is atomized in an oxygen-free atmosphere by means of a hydrocarbon in liquid form such as paraffin, and the moist powder, still hot (60-80 °C), is transferred to a container (1) and supported therein on a screening member (2). A negative pressure is first applied below the screening member (2) so that liquid is drawn from the powder mass. An inert gas, substantially free from oxygen, is then circulated through the powder mass, whereupon vapour absorbed by the gas is condensed before the gas is recirculated to the container (1). A circulation circuit (70) for liquid atomizing medium joins the gas-circulation circuit (20) at a liquid jet pump (30).

Inventor: PETIT GUIDO HENRI MARGUERITE
IPC: H04L12/54
Filed: 1999-02-04
Abstract: The present invention relates to a method and related devices to be used for cell discard in a communications-network through which cells arranged in frames are transmitted. This communications-network exists of a first discarding device which is coupled to a second discarding device. This first discarding device can be a traffic policer or alternatively a network buffer.  The second discarding device is a network buffer. A cell stream is supplied to the first discarding device.      The system determines if the incoming cells are in accordance with the predetermined criteria and discards this cell, if the cell is not in accordance with the criteria. By discarding cells of a frame, this frame is corrupted and marked with a corrupted frame indicator, by the first discarding device. Afterwards the second discarding device may discard the remaining cells of the marked frame.      If the first discarding device is a traffic policer, the traffic policer checks the conformance of the incoming cells according to conformance criteria and alternatively if the first discarding device is a network buffer it checks the conformance of the incoming cells according to some congestion determining criteria.

Inventor: VALLEE RICHARD
IPC: H04L12/26
Filed: 1997-08-14
Abstract: In ATM networks, digital data in ATM cells are sent to a destination node over more than one transmission link in round robin fashion. This is called inverse multiplexing. At connection start-up, the source node informs the destination node of the specific round robin fashion of the transmission links so that the ATM cells are reassembled in a proper sequential order. Inverse multiplexing control cells are used to communicate between the source node and destination node for connectivity testing of transmission links. Cell stuffing is also provided in one embodiment to accommodate non-synchronized links among transmission links. In a particular embodiment, two consecutive control cells indicate a stuffing cell. A start-up procedure is described when not all the transmission links are usable.

Inventor: KAWADA KOJI
IPC: C01B5/00
Filed: 1998-06-12
Abstract: Process for generating moisture for use in semiconductor manufacturing, the process comprising feeding hydrogen and oxygen into a reactor provided with a platinum-coated catalyst layer on an interior wall, thus enhancing the reactivity between hydrogen and oxygen by catalytic action and instantaneously reacting the reactivity-enhanced hydrogen and oxygen at a temperature below the ignition point to produce moisture without undergoing combustion at a high temperature, wherein the amount of unreacted hydrogen occurring in the generated moisture in starting up or terminating the moisture generating reaction is minimized and wherein undesired reactions such as undesired silicon oxide film coating are avoided. When the generation of moisture is started up by feeding hydrogen and oxygen into the reactor provided with a platinum-coated catalyst layer on the inside wall thereof, oxygen first starts to be fed and, some time after that, the supply of hydrogen is begun. In terminating the moisture generating operation by cutting off the supply of hydrogen and oxygen into the reactor, the feeding of hydrogen is first stopped and, some time after that, the supply of oxygen is shut off.

Inventor: KOENIG ROBERT H
IPC: G01F23/24
Filed: 1999-04-12
Abstract: An automatic sub-floor pumping system, having a controller box, sensor wires, suction hose and pump. Two or three sensor probes are used - the lowest, or ground, probe can be omitted, and the circuit referenced to earth or wiring ground. The pump evacuates water from beneath the basement floor through a hose inserted into a small hole drilled into the basement floor. The sensor probes can be simply wires with the last 1/8" to 1/2" bared, attached to the outside of the pump suction hose at two locations an inch or two apart. The hose, with wires attached, is inserted down the one-inch evacuation hole bored through the floor. The control uses a very low current on the wires, which are negative relative to ground so as to be cathodically protected from corrosion. An optional sensing circuit monitors lower probe wire voltage and warns of possible corrosion effects.

Title: Talking remote control with display
Inventor: CHANG ALLEN
IPC: H04N5/44
Filed: 1997-10-08
Abstract: A remote controller includes a display screen (12) and a speaker (14). The remote controller receives and stores transmitted television program information, preferably including an electronic program guide (EPG).  Preferably the program information is transmitted over a wireless paging system (Fig. 6) at a preferred frequency of about 900 MHz. A microcontroller (46) in the controller includes a digital signal processor for sorting and storing the retrieved program information. In response to a viewer command input through a keypad (15) on the remote controller, the microcontroller selectively retrieves and displays at least a portion of the program information on the display screen of the remote controller. The display changes as the viewer changes channels or scrolls through the EPG. The remote controller also has a voice message function. When the voice message function is activated, the microcontroller retrieves and processes a voice message for announcement through the speaker. The voice message corresponds to the television program currently displayed on an associated television system or a selected program in the EPG.
