Title: Method for controlling memory consumption in router-based virtual private networks
Inventor: ROSENBERG ERIC
IPC: H04L9/32
Filed: 2006-06-27
Abstract: A method to determine the maximum number of VPNs assignable to plurality of routers in a VPN network. The first step in the method can be specifying a tolerance which is a probability that consumed router memory will exceed available router memory for each router i n a plurality of routers. The second step can be computing the consumed router memory on each router in a plurality of routers by summing a route memory, an interface memory, a VPN memory, and a constant memory. The third step can be computing a number [V] of VPNs assign ed to the router to insure that, with the specified probability tolerance, the consumed router memory will not exceed the available router memory for each router in a plurality of routers.</SDOA B>

Title: Arrangement in connection with crosscutting saw of harvester
Inventor: HUTTUNEN MARKKU
IPC: A01G23/091
Filed: 2004-12-21
Abstract: The present invention relates to an arrangement in connection with a crosscutting saw of a harvester (1). Herein, a lattice-like structure composed of strips (17) is provided in a saw casing (10) of the crosscutting saw, the structure being substantially on the same section plane as the rotational movement of a chain (12) of the crosscutting saw. The strips are arranged in the saw casing in such a manner that substantially each movement path tangent generated at a lower edge (16) in a guide bar (13) of the chain or at an outer track (20) on the side of the saw casing in the chain wheel is arranged to encounter a surface (19) in the strip. This provides a structure that enhances a controlled removal of sawdust or other pieces flowing to the saw casing (10) during sawing.
Patent CA-2551727-A1 (CA)
Inventor: BELL DOUGLAS N
IPC: C25B1/04
Filed: 2006-07-06
Abstract: An electro-hydrogen generator consisting of a rotary-driven cylindrical vessel which produces gravities of sufficient magnitude to promote the elimination of the bubble blanket that causes increased resistance in standard electrolysis. A high speed movement of electrodes is used to facilitate the separation of hydrogen gas and oxygen from an electrolytic solution. The external electrodes, comprising a cathode nearer the center and an anode nearer the periphery separated from each other by a fixed bar within a slot, move outward from the center of the cylindrical vessel toward the periphery of the vessel as the cylinder spins centrifugally. The movement of the charges creates increased potential difference with the electrolytes, facilitating the dissociation and migration of the hydrogen and oxygen molecules within the solution. Water is added peripherally to replace the spent electrolyte, maintaining electrolyte concentration and conductivity at suitable levels. Safety measures are also disclosed due to the explosive nature of hydrogen gas. These measures include shunting the hydrogen gas via vents, blowers, venturi outlets and turbines; using domed or slanted ceilings to collect leaked hydrogen from enclosed spaces; and using a secondary bag or chamber to trap escaped hydrogen.

Patent CA-2552808-A1 (CA)
Title: Lighting control device having improved long fade off
Inventor: KEAGY JON MICHAEL
IPC: H05B39/08
Filed: 2004-12-30
Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes a microcontroller and a user-actuatable switch controller that is operatively coupled to the microcontroller. The microcontroller causes the light intensity level of the lamp to fade at a first fade rate when the switch controller is actuated. If the microcontroller determines that the switch controller has been actuated for at least a predefined actuator hold time, the microcontroller causes the light intensity level of the lamp to fade at a second fade rate for a predefined long fade time. After the long fade time elapses, the microcontroller causes the light intensity level of the lamp to fade to off at a third fade. The first fade rate is based on a predefined fade-off time that represents a time allotted for fading the ligth intensity level of the lamp from its initial light intensity level to off. To prevent the light intensity level from fading to off before the actuation time elapses, the fade off time may be defined to be longer than the actuation time. The second fade rate may be slower than the first fade rate and have an exponential fade profile. The third fade rate may be a predefined rate at which the microcontroller is programmed to cause the light intensity level to fade from full on to full off. The third fade rate may be quicker than the second fade rate.
