Patent CA-2414097-A1 (CA)
Title: Apparatus for intermittent liquid dispersal
Inventor: MCKENNA QUENTIN M
IPC: B05B1/08
Filed: 2001-06-20
Abstract: Valve (10) for the periodic and cyclic or otherwise intermittent release of a fluid is described along with an irrigation sprinkler (5) incorporating the valve (10). The valve opens when a critical pressure level is reached in a reservoir (12) attached to the valve, thereby permitting a portion of the fluid contained within the reservoir (12) to be released through the valve. As the fluid is released, the pressure in the reservoir decreases. The valve does not close until the pressure level in the reservoir reaches a second pressure level that is below the critical pressure level. When the reservoir (12) is refilled from a pressurized source at a controlled rate that is less the rate at which the fluid is expelled through the valve when open, the valve (10) will cycle repetitively.

Abstract: Disclosed is a system providing a VPN service by connecting a VPN (Virtual Private Network) to a mobile communication network. A home agent (HA) stores location information of a mobile node (MN) and information on whether the MN  is registered in the VPN. A foreign agent (FA) transmits a location registration request message to the HA by receiving location registration information of the MN, and transmits data to an ISP (Internet Service Provider) router in the same subnet upon receiving a VPN service request. A  server provides the VPN service and a router network connects the VPN to the FA. The router network includes a server for searching an edge IP router in the network using an address of the FA. The HA prevents an MN from accepting a call request received from a specific node in an IP network while the MN is performing a VPN service.
