IPC: C10J3/72
Filed: 1998-06-05
Abstract: The system for controlling oxygen flow in a gasification process of the instant invention comprises a suction control valve located between the oxygen source and the oxygen compressor. The suction control valve is adapted in order to open to deliver oxygen from the source to the compressor through the first pipe and to move to a reduced flow positon to prevent excess delivery of oxygen from the source to the compressor. The system also comprises a second pipe which operably connects the oxygen compressor to a port of a gasifier. The system comprises a normally closed vent valve located between the oxygen compressor and the port of a gasifier. The system comprises a means located in the gasifier or in the gasifier effluent for detecting when it is necessary to change the oxygen flow to the gasifier and to actuate the suction control valve sufficient to change the oxygen flow.  Finally, the system comprises a means for a means of controlling the suction control valve and the vent valve to regulate the quantity of oxygen delivered to the gasifier.

Title: System and method for selecting and accounting for value-added services with a closed system meter
Inventor: ALLPORT ROBERT W
IPC: G07B17/00
Filed: 1999-12-10
Abstract: System and method are provided for selecting and accounting for value--added services with a closed system metering device. A scanning device coupled to the closed system postage meter scans information, including recipient address, printed on a mailpiece. From the scanned information or manual selection, a selection of value-added services is made and the closed system metering device performs accounting related to the selected value--added services. The recipient address is combined with other information relating to postage payment for the mailpiece to obtain postal data relating to the mailpiece. The postal data is used to generate an indicium, which includes cryptographic evidencing of postage payment. A graphical representation of the selected value-added services is added to the generated indicium to generate a value-added indicium, which is then printed on the mailpiece.

If the agent is determined to be busy on a video call (102, 104) or busy on a telephone call (106, 108), an Agent Busy result is returned (116). If the agent is determined not to be busy on either a video call (102, 104) or on a telephone call (106, 108), a determination is made as to whether the number of unanswered mails (e.g., electronic mail (e-mail) messages, voice mail messages, and video messages) for the agent exceeds a preset limit (110, 112). If the number of unanswered mails for the agent is determined to exceed the preset limit (110, 112), the Agent Busy result is returned (116). If the number of unanswered mails for the agent is determined to be equal to or less than the preset limit (110, 112), an Agent Available result is returned (114).

Inventor: EGUCHI TAKAHIRO
IPC: B60W10/105
Filed: 2000-07-10
Abstract: A vehicular transmission comprises an engine E, a continuously variable transmission CVT and a starting clutch 5. The driving force from the engine E is conveyed through the continuously variable transmission CVT with a speed change to a countershaft 2, and the starting clutch 5 is used to convey this driving force from the countershaft 2 to wheels of a vehicle. The continuously variable transmission CVT is hydraulically controlled by a control valve CV which receives control signals through a line 35 from an electrical control unit ECU. When the temperature of the oil used for engaging and disengaging the starting clutch 5 is equal to or higher than a predetermined temperature, the transmission allows the engine E to stop operating. This control to terminate the operation of the engine is an idling elimination control and is achieved by terminating the fuel supply to the engine and by maintaining the resulting condition of non-fuel supply while the vehicle is being decelerated and brought into a halt.

Abstract: The invention relates to a method for controlling the acceptance or refusal of a new connection on an ATM communications device having a maximal capacity R max which already handles a plurality M  of connections that can be statistically multiplexed, whereby the new connection has a peak cell rate PCR and a sustainable average cell rate SCR. The inventive method comprises the following steps: Determining the sum P M+1 = .SIGMA.PCR1 of the peak cell rate PCR, the sum S M+1-.SIGMA.SCR1 of the sustainable cell rate SCR of the M existing connections, and the new connection; determining the variance V of the cell rates of the M+1 connections;  determining the required capacity load M+1 for the M connections according to P M, S M and V, and; accepting the connection in the case when load M+1 is less than or equal to R max. The connection acceptance control can be carried out faster, more effectively and independent of the sequence of accepted connections by the exact calculation of the required capacity of the communications connections.

Filed: 2000-11-22
Abstract: A method for use in a block transform-based coding system of processing (e.g., encoding and/or decoding) one or more block transform coefficients associated with at least one block of visual data (e.g., an image and/or video sequence) comprises the following steps. First, one or more previously reconstructed block transform coefficients associated with the visual data are identified. Then, a context selection value is computed for use in processing a block transform coefficient associated with the at least one block, the context selection value being based on the one or more previously reconstructed block transform coefficients. The context selection value may be computed as a function of one or more values respectively associated with one or more previously reconstructed block transform coefficients in near proximity, with respect to a scanning order, to the block transform coefficient to be processed. Further, the context selection value may be computed as a function of a spatial frequency associated with the block transform coefficient. Still further, the context selection value may be computed as a function of both the one or more values respectively associated with the one or more previously reconstructed block transform coefficients in near scanning order proximity and the spatial frequency associated with the block transform coefficient.
