Title: Network access system including a programmable access device having distributed service control.
Inventor: THOMAS HOWARD LEE
IPC: H04L12/56
Filed: 2001-11-28
Abstract: A distributed network access system in accordance with the present invention includes at least an external processor and a programmable access device. The programmable access device has a message interface coupled to the external processor and first and second network interfaces through which packets are communicated with a network. The programmable access device includes a packet header filter and a forwarding table that is utilized to route packets communicated between the first and second network interfaces. In response to receipt of a series of packets, the packet header filter in the programmable access device identifies messages in the series of messages upon which policy-based services are to be implemented and passes identified messages via the message interface to the external processor for processing. In response to receipt of a message, the external processor invokes service control on the message and may also invoke policy control on the message.

Patent MX-PA03005452-A (MX)
Title: Method to configure a bluetooth logical link control and adaptation protocol channel.
Inventor: GILBERTO LOUIS J
IPC: H04L29/06
Filed: 2003-06-17
Abstract: A technique to simplify L2CAP channel creation/configuration for a node is presented. The method enables a node to determine how involved it is in the L2CAP channel connection creation and management process. There are three levels of participation that the node may specify. The three levels are no involvement at all, minimal involvement, and total involvement. In no involvement, the channel is dropped if a remote node does not accept all node specified parameters. In minimal involvement, the channel is dropped if a remote node does not accept all node specified parameters and the node is notified when the connection has been disconnected by a remote disconnect or HCI link loss. In the total involvement level, the node is fully involved in the channel creation/configuration. The node provides a function pointer that is called to confirm or reject parameters. If a parameter is unacceptable, the connection is disconnected.

Title: Method for coating the wet perimeter of a channel traditionally coated with concrete, with glass fiber-reinforced polyester.
Inventor: MENDIVIL FIERRO RAFAEL
IPC: C08L67/00
Filed: 2004-12-13
Abstract: Described herein is a channel traditionally coated with cement which wet perimeter is coated with polyester reinforced with glass fiber, so as to obtain a totally hermetic channel. Nowadays, within the engineering technical sector pertaining to the management of hydraulic resources, channels coated with cement are not hermetically manufactured, thereby presenting conduction losses (of about 15% of the conducted flow). The advantage of the channel of the present inention is that it eliminates conduction losses, it is also useful for waterproofing already existing hydraulic structures, such as dams, concrete gravity dams, weirs or rollways, impounding structures, siphons, sewers, sheet piles, derivative dam bridges, outlets, piping and in general all structures useful for working with liquids (particularly water) and supporting the action thereof.
