Title: Access technique of channel hopping communications system
Inventor: HAARTSEN JACOBUS
IPC: H04W52/02
Filed: 1999-10-01
Abstract: Etablishing a connection between a paging unit and a standby unit in a channel hopping communications system includes activiting the standby unit for an activation time period out of every standby time period. During each activation time period, the standby unit monitors a selected channel for receipt of a paging message. The selected channel is selected from a plurality of channels, and, for each subsequent activation time period, the selected channel is a subsequent one of the plurality of channels as specified by a hopping sequence and an internal clock. A page train is repeatedly transmitted from the paging unit to the standby unit, until a response is received from the standby unit. Each page train includes a plurality of paging messages, each paging message being transmitted on a different one of a subset of the plurality of channels. Selection of a page train for transmission by the paging unit may be based on an estimate of the standby unit's internal clock.  The generation of page trains can be further optimized for those cases in which more than two page trains will be transmitted. The purpose of the optimization is to generate page trains that, when transmitted, are most likely to elicit an early response from the paged unit.

Patent CA-2352723-A1 (CA)
Inventor: MCNAMARA JASON A
IPC: B65G23/40
Filed: 2001-07-09
Abstract: A conveyor ratcheting apparatus for advancing a conveyor in one direction in discrete steps. A ratchet arm is pivotally supported on a frame.  A ratchet actuator drives the aim reciprocally between first and second positions. A ratchet wheel is rotatably supported on the frame. Circumferentially spaced teeth are formed around an outer rim of the ratchet wheel. The ratchet arm sequentially engages each of the teeth and causes the ratchet wheel to rotate in one direction each time the ratchet arm engages one of the teeth and moves toward the second position from the first position. The ratchet arm disengages whenever the ratchet arm moves from the second position back toward the first position. A detent engagement member is supported on the frame and is moveable into engagement with one of four stop detents in the ratchet wheel when the first ratchet arm is in the second position. The detent engagement member positively holds the ratchet wheel and allows ratchet wheel rotation out of the second position only after being disengaged. An actuator is operatively connected to the detent engagement member and disengages the detent engagement member in response to ratchet arm movement and before the ratchet wheel is rotated out of the second position.

Title: Illegal access data handling apparatus and method for handling illegal access data
Inventor: MIYAGAWA AKIKO
IPC: H04L29/06
Filed: 2001-10-25
Abstract: To provide a centralized control system for defending and taking countermeasures against an illegal access. A network device 3 detects an illegal access packet P1 transmitted from an illegal accessor's terminal 6, and transfers an encapsulated packet P2 of the illegal access packet P1 to a data center 1. A control system 11 in the data center 1 analyzes the packet P2, encapsulates a response packet P4 from a decoy server 13 pretending to be a response from a target server to be attacked 5 to acquire a packet P3, and then transmits the packet P3 to the network device 3. The network device 3 decapsulates the packet P3 so as to extract a response packet P4, and transmits the response packet P4 to the illegal accessor's terminal 6. The illegal accessor's terminal 6, upon reception of the response packet P4, would believe that the response packet P4 should be transmitted from the server 5, and start to illegally access the decoy server 13.

The chemical customer may order chemical products online which are categorized based on the degree of hazard they pose. A defined set of criteria is applied to all products offered for sale, such as high risk, low risk, custom or no risk. The degree of screening of the customer prior to the sale is based upon the degree of regulation an ordered product is given by some government agency, or the level of safety and environmental concern the product may pose to workers, the public and a general environment. The system of the present invention provides for the screening of customers of hazardous products to ensure that the customers have procedures in place for handling emergencies related to the products. Furthermore, the system and method of the present invention allows the screening of customers to ensure that information relative to the customers preparedness to handle emergencies is gathered and stored prior to shipping of the product.

Abstract: This invention relates to a system and method of exchanging first points held by a customer for second points, wherein the first points that are issued by a first point issuer differ from the second points that are issued by a second point issuer. This method comprises the steps of permitting the customer to set a first number of first points to be exchanged and permitting the first and second point issuers to set the point withdrawal and deposit rates of their first and second points respectively. Next, an equivalent number of the second points is determined based upon the point withdrawal and deposit rates of the first and second point issuers respectively, and the first number of the first points. Then, she first number of points is exchanged for a second equivalent number of second points.
Patent CA-2380060-A1 (CA)
Title: Gain flattening with nonlinear sagnac amplifiers
Inventor: DIGONNET MICHEL J F
IPC: G02F1/365
Filed: 2000-07-12
Abstract: An apparatus and a method provide gain flattening in communications systems wherein a large number of optical signals at different wavelengths must be amplified while maintaining signal power within an acceptable range. Because of differences in gain of typical optical amplifiers as a function of wavelength and input power, the signals at different wavelengths are not amplified by the same amounts. Thus, when amplified multiple times, certain signals tend to become severely attenuated to the point of being no longer useable. The present gain flattening apparatus and method cause signals having higher gain-power products to be attenuated by a greater amount in response to Kerr-induced phase shifting such that after multiple stages of amplification, all the signal powers converge toward a small range of acceptable output powers. The apparatus provides amplification, multiple times, of a series of signals with a plurality of wavelengths covering a very wide spectral range, while maintaining the power of all the signals within a small range. The spread of this signal power range is robust against changes in the signal power, against changes in the number of signals, and, to some degree, against changes in the amplifier's pump power. The apparatus design is also robust against manufacturing changes in the parameters of the apparatus' components.  The apparatus and invention are preferably implemented as multiple nonlinear Sagnac amplifiers having erbium-doped fiber amplifiers positioned asymmetrically in an interferometer loop.

Inventor: MARINO RONALD A
IPC: H01P1/18
Filed: 2000-09-13
Abstract: An antenna arrangement is provided with a variable parasitic element whose position is varied as a function of the scan angle. According to an exemplary embodiment of the invention, a variable scanning array dual polarized antenna provides different scan angles by varying phase elements of the array.  According to this embodiment an adjustable phase shift mechanism is used to modify the phase of the antenna array. The adjustable phase shift mechanism used changes the antenna's phase as a function of a moveable dielectric slab.  The dielectric slab slides over a microstrip line that results in a phase change that is a function of line coverage. A parasitic element is also connected to the dielectric slab such that the position of the parasitic element is varied in response to a change in the phase shift mechanism thereby varying the canceling signal of the parasitic element to optimize port isolation for the dual polarized antenna.
