Patent CA-2280349-A1 (CA)
Inventor: BURNS GEOFFREY FRANCIS
IPC: H04B1/7075
Filed: 1999-08-18
Abstract: A vector generator generates one or more pseudo-random noise PN sequences as matched-filter PN vectors for a matched-filter correlator of a code division, multiple-access (CDMA) demodulator. The period and clock of the local PN code sequence may be employed as a time reference, and each matched-filter PN vector has a known code-phase offset with respect to the local PN code sequence. Matched-filter PN vectors having a chip-length on the order of a data symbol period, such as 64-chip sequences, are generated within a short period of time compared to the period of the local PN code sequence. A state of the local PN code sequence is periodically captured from the local PN code sequence, which state is employed by a PN generator generating a similar PN code sequence but clocked at a higher rate. Consequently, a series of offset PN  code sequences are generated in advance of the local PN code sequence. Combined with single or parallel offset masking, any desired matched-filter PN vector may be generated from the offset PN code sequences within a short period when compared to the period of the local PN code sequence. The generation time of each matched-filter PN vector may be 1-chip period in duration. A vector correlator of a RAKE receiver may employ the vector generator in a CDMA communication system. Consequently, the vector generator provides the vector correlator with matched-filter PN vectors for a matched-filter, multiple-finger search. The vector generator allows for time-multiplexed generation of the matched-filter PN vectors.
Patent CA-2280529-A1 (CA)
Inventor: WOODRUFF KEITH FLOYD
IPC: A01C17/00
Filed: 1999-08-19
Abstract: A meter assembly provides for dispensing a material, and in particular, a granular chemical agricultural material, from a moving device driven over terrain to be treated with the material. The device has a metering system for dispensing the material including a rotatable apertured disk for metering material from a product container and dispensing the material in controlled metered quantities. The metering disk is removable from its operating position within the dispensing device for inspection, repair or replacement purposes, without disassembling the overall apparatus, and a guide is provided for returning the metering disk to its operating position within the dispensing device. The apertures in the metering disk are oriented so that each aperture partially overlaps each adjacent aperture to result in continuous flow of the metered material through the metering disk as it rotates.

Patent CA-2308526-A1 (CA)
Inventor: JAMES DONALD E
IPC: H01M10/44
Filed: 2000-05-11
Abstract: Apparatus and method are provided for measuring the series resistance of each individual cell of a battery bank for establishing the readiness of the batteries. The invention comprises a switch in series with a load, connected across each cell of the battery. An electronic switch momentarily imposes the load on the cell and the value of the current drawn from the battery and the voltage across it is measured with an A/D device. A controller directs a plurality of the switched loads on a plurality of cells. The A/D device and controller on each cell communicates their measurements to a remote host computer, preferably via an RF serial modem. The host computer calculates the internal resistance and provides alarm and other reporting functions. Further, as the measurement imposes a small energy drain on the cell, through independent adjustment of the frequency of measurement for each cell, over-charging of the individually cells can be equalized.

Title: Method and system for algorithm-based address-evading network snoop avoider
Inventor: GENTY DENISE MARIE
IPC: H04L12/46
Filed: 2000-06-20
Abstract: A method and system for an algorithm-based network snoop avoider is provided.  A first data processing system and a second data processing system communicate on a physical network by transmitting data packets on the network using a virtual private network (VPN). Data packets are transmitted through a first VPN tunnel between the first data processing system with a first network address terminating a first end of the VPN tunnel and the second data processing system with a second network address terminating a second end of the first VPN  tunnel. The VPN is automatically reconfigured to use alternate addresses on the network for the tunnel endpoints by automatically determining, in accordance with a predetermined algorithm, a third network address and a fourth network address and by automatically assigning the third network address to the first data processing system and the fourth network address to the second data processing system. Data packets may then be transmitted through a second VPN tunnel in which a first end of the second VPN tunnel is terminated by the first data processing system using the third network address and a second end of the second VPN tunnel is terminated by the second data processing system using the fourth network address. The data packets may be transmitted using Internet Protocol (IP), and a portion of the network may include the Internet.

Title: Method of removing water and contaminants from crude oil containing same
Inventor: SHAW FRED
IPC: C10G7/04
Filed: 2000-07-10
Abstract: A method for contaminant and water removal from crude oil. The method involves recirculating at least a portion of the dewatered crude into a dehydrator. The dehydrator contains a heated dehydrated crude oil and the surface or adjacent thereto is maintained at a temperature sufficient to vaporize any water contacting the surface from crude oil to be treated in the dehydrator. It has been found important to maintain a substantially uniform temperature at or below the vaporizing surface in order to effectively treat crude oil for dewatering purposes. Significant temperature fluctuations are typically realized by dehydrators since heat enthalpy is removed in order to vaporize the water in the crude oil. Such fluctuations lead to process complications and upset and are therefore undesirable. The instant invention recognizes this limitation and substantially reduces foaming and provides for a smoothly running and efficient dehydration process.

The flexible liner is secured to the respective ends of the tubular body wall by way of an adhesive band between the liner and the inner surface of the tubular body wall. The flexible liner thus has a free medial portion between the end portions which moves inwardly against the expansible food product when a vacuum is applied during packaging, and which also then moves outwardly against the inner surface of the tubular body wall as the product expands. The liner preferably comprises a flexible and stretchable liner formed of at least one polymeric layer without foil and paper layers.
