Title: Device and method for exchanging frame messages of different lengths in cdma communication system
Inventor: KIM YOUNG-KY
IPC: H04W76/02
Filed: 1999-03-15
Abstract: In a transmission device and method for a CDMA communication system, when a shorter frame message is generated during transmission of a longer frame message, the transmission of the longer frame message is interrupted, whereupon the shorter frame message is immediately transmitted in place of a portion of the longer frame message. In one embodiment, after the longer frame message is interrupted and the shorter frame message is transmitted, only the tail portion of the longer frame message is transmitted thereafter. That is, the replaced portion of the longer frame message is not transmited following the shorter frame message transmission. In an alternative embodiment, following the shorter frame message transmission, the remainder of the longer frame message, from the point of interruption, is transmitted in its entirety. In the latter case, the longer frame message is delayed by the length of the shorter frame message.

Title: System, apparatus, and method for geographic positioning of marine fauna
Inventor: GUDBJORNSSON SIGMAR
IPC: G01S19/42
Filed: 1999-02-23
Abstract: A system, apparatus, and method for determining positions of underwater animals involves emplacement of an acoustic transponder on the animal and establishing communications with a transponder carried by a vessel whose position can be determined by receiving signals from an external source such as a GPS satellite in order to establish proximity of the animal to the vessel, the position of the vessel then being adopted as the position of the animal. Communications can be established either by communicating the position of the transceiver to the equipment on the animal for storage therein, or by communicating the identity of the animal to the vessel whose position has been determined for association with the position, and subsequent local storage on the vessel and/or communication to a central station.

Title: Process for the polymerisation of olefins in the gas phase
Inventor: MADDOX PETER JAMES
IPC: C08F10/02
Filed: 1997-06-27
Abstract: A process for the polymerisation of olefins in the gas phase is carried out in the presence of a supported transition metal catalyst. The process involves a prepolymerisation step which may be performed in-situ and in particular the prepolymer may be prepared in the dry phase. The catalyst may for example comprise a constrained geometry transition metal complex supported on silica and used in the presence of an activator. The prepolymerisation step unables the activity of the catalyst to be improved.

Abstract: Nozzle jet drill bits for drilling drainholes from a wellbore are provided in a 4 1/2-inch or larger casing. The drills are small enough to allow use of a bit diverter to turn the bits about 90 degrees in the casing when attached to an elastomeric high-pressure tube. Pumping of fluid, which may contain abrasive particles, through the bits allows drilling though the wall of casing, if present, and continued drilling into a formation surrounding the well without withdrawing the bit from the well. Direction-indicating instruments and geophones may be used to measure or monitor direction and location of the bit. One type of jet drill that may be used can change direction of drilling by controlling pressure at the bit.

Patent CA-2307911-A1 (CA)
Inventor: DAWES NICHOLAS W
IPC: H04L47/27
Filed: 2000-05-09
Abstract: Methods which determine network performance by determining not only the transit delay between nodes in a network but also the variance, or jitter, of such transit delays. A common node, usually a network management computer (NMC), sends out a signal to a first node of interest and measures the time before it receives an acknowledgment from the first node. The NMC then sends out a similar signal to a second node of interest and similarly measures the time required to receive an acknowledgment. Based on these two measurements, the transit delay between the first and second nodes can be calculated if the first node lies on the path between the NMC and the second node or vice versa. For a multiple node communications path, the total transit delay between any two nodes is the sum total of the transit delays between adjacent nodes lying on the path. In the case of meshed networks, where a path to a node may be ambiguous, additional measurement nodes strategically positioned in the network can be used such a way that the transit delay between any adjacent pair of nodes can be calculated unambiguously from at least one of these measurement nodes, i.e., the portion of the network being measured will be reduced to a hierarchical one with respect to at least one of the measurement nodes.
