Filed: 1999-07-27
Abstract: A method of communicating between a plurality of devices in a controller area network is disclosed. The method includes a first device transmitting a first message over the network, a second device comparing a first value in the first message with a second value, and a third device responding to messages it receives over the network. The method may involve a number of producer devices and a consumer device. The consumer device responds to messages sent as instance zero. The method may involve a number of producer devices, an intermediate consumer and a consumer device.  The producer devices send their messages as instances other than zero. The intermediate consumer receives the messages from the producer devices, compares them, and sends messages as instance zero to the consumer device. The producer devices may be thermostats, actuators, sensors, etc. The consumer device may be a furnace, an air conditioner, etc.

Title: Method for determining barriers to reservoir flow
Inventor: RUNNESTRAND SCOTT A
IPC: G01V1/30
Filed: 1998-01-30
Abstract: A method and apparatus for predicting barriers to fluid flow in a subterranean reservoir using well data (18) and 3-D seismic data (16, 18) are disclosed, where a preferred first step (82) in the method models petrophysical properties of the reservoir to provide model logs which are expressible as continuous curves of a reservoir property as a function of depth. The next step (84) selects individual data points on the continuous curves, which traverse a subterranean layer, and assigns a flow or nonflow state to each data point based on comparing a threshold value of a reservoir property with the value predicted by the data point. The layer is divided into a multitude of subvolumes each containing a single data point, and then a connectivity factor, which considers multiple flow paths around each data point, is calculated for each subvolume. The subvolumes are then grouped into larger volumes called simulation cells, and directional flow numbers are assigned to the cells relative to three mutually perpendicular x, y and z coordinate axes, such that display of the directional flow numbers for a group of cells demonstrates flow barriers and flow paths in the reservoir.

Title: Semantic errors diagnostic operation for multi-agent system
Inventor: CHOI DANIEL
IPC: G06F11/00
Filed: 2000-02-02
Abstract: A method and apparatus for automatically locating sources of semantic error in a multi-agent system based on setup connection tree information, and informing the appropriate agents so that they can avoid using the faulty resources in the future. The setup connection tree model is established based on patterns of agent actions for expressing the logical relationship between available resources in the disjunctive normal form (d.n.f.). A table is used to record different sets of resources for use in the resource selection process. Thus, faulty resources can be located by means of induction. A global database is also maintained for updating information on semantic errors in the system.

Title: Pattern recognition using multiple reference models
Inventor: ARIYAEEINIA ALADDIN MOHAMMAD
IPC: G10L17/00
Filed: 1998-10-14
Abstract: A method and apparatus for pattern recognition comprising comparing an input signal representing an unknown pattern with reference data representing each of a plurality of pre-defined patterns, at least one of the pre-defined patterns being represented by at least two instances of reference data. Successive segments of the input signal are compared with successive segments of the reference data and comparison results for each successive segment are generated. For each pre-defined pattem having at least two instances of reference data, the comparison results for the closest matching segment of reference data for each segment of the input signal are recorded to produce a composite comparison result for the said pre-defined pattem. The unknown pattem is the identified on the basis of the comparison results.  Thus the effect of a mismatch between the input signal and each instance of the reference data is reduced by selecting the best segments from the instances of reference data for each pre-defined pattern.
Patent CA-2304884-A1 (CA)
Inventor: DURNEZ FRANCOIS
IPC: H04B7/26
Filed: 2000-04-07
Abstract: The invention relates in particular to a TDMA transmission system including transmitters synchronized to a single receiver, each of the transmitters being able to transmit to the receiver on a given carrier frequency bursts with lengths which are all multiples of that of a unit burst including a guard time, the unit bursts including at least one guard time and the receiver being adapted to receive simultaneously bursts from different transmitters. According to the invention, each transmitter includes means for inserting a filler sequence into each burst to be transmitted at each location of the burst that is likely to correspond to a guard time in a burst received simultaneously on a different carrier frequency. The invention reduces the harmful effects of interference if the time of reception of the guard time of a burst on a first carrier frequency corresponds to the time of reception of information symbols in another burst received simultaneously on another carrier frequency.

Filed: 1998-10-16
Abstract: This invention relates to methods of reconfigurating a cell. Each signalling channel (SDCCH/8) contains a number of dedicated control channels (SDCCH). The invention can be divided into two parts, an increase condition in which a traffic channel (TCH) is converted to a signalling channel (SDCCH/8) and a decrease condition in which a signalling channel is reconverted to a traffic channel. The increase condition comprises the step of increasing the basic configuration by configure a traffic channel (TCH) to a dedicated control channel (SDCCH/8) if the channel utilization indicates that the basic configuration would have given a certain congestion level. The decrease condition comprises the step of decreasing the basic configuration by configure a dedicated control channel (SDCCH/8) to a traffic channel (TCH) if the channel utilization indicates that the basic configuration would have given a certain congestion level.

Abstract: A fifth wheel ball hitch latching assembly includes a housing, a funnel mounted within the housing and defining a conical-shaped passage for guiding movement of a ball hitch into the funnel through an open bottom end thereof toward an open top end thereof as the housing is lowered onto the ball hitch, a shaft mounted in the housing to undergo movement along a longitudinal axis of the housing between raised and lowered positions, the shaft having a lower end extending through the open top end and into the passage of the funnel and biased toward the lowered position, a pair of latch dogs extending through slots in the funnel and being movable away from and toward the longitudinal axis of the housing between retracted and extended positions, a linkage pivotally connecting the shaft with the latch dogs such that movement of the shaft between the lowered and raised positions causes the latch dogs to correspondingly move between the retracted and extended positions such that insertion of the ball hitch through the open bottom end of the funnel brings the ball hitch into contact with the lower end of the shaft causing the shaft to move from the lowered to raised position and thereby cause the latch dogs to move from the retracted to extended position such that the latch dogs capture the ball hitch within the funnel and thereby couple the ball hitch to the trailer tongue, and a locking mechanism mounted on the housing and extending adjacent to the shaft and after movement of the shaft to the raised position being actuatable from an unlocked to locked condition so as to retain the shaft at the raised position and thereby retain the latch dogs at the extended position.
