Title: Seamless roaming across wireless subnets using source address forwarding
Inventor: KOEHLER YANNICK
IPC: H04L69/14
Filed: 2006-12-29
Abstract: To enable devices to detect L3 roaming users and to take appropriate forwarding actions, L3 knowledge is introduced inside a bridge in a non-intrusive way. In particular, as a client moves from a subnet associated with a first network element to a subnet associated with a second network element, a determination is made regarding whether the client is roaming. This is done by evaluating a source IP address within a L3 packet header within a first frame received at the second network element. If, as a result of the evaluating step, it is determined that the client is roaming, an L2 bridge forwarding table in the second network element is configured to include a source MAC address of the client together with information identifying at least a destination interface for use in directing client data traffic back towards the subnet associated with the first network element. The first frame is then forwarded. In one embodiment, the traffic is directed back towards the subnet associated with the first network element via a GRE encapsulation tunnel, although any convenient tunneling mechanism can be used. According to another feature, given information cached at the foreign access point is used to enable the roaming client to continue to seamlessly receive inbound traffic prior to or during the configuration of the L2 bridge forwarding table (i.e., before any outbound traffic is actually sent from the client).

Abstract: An automatic focusing system comprises at least one micromirror array lens, an image sensor, and a signal processor. The micromirror array lens images an object and focuses the image on the image sensor. The image sensor receives the light and converts the photo energy of the light to electrical energy in the form of an electrical signal. The image sensor sends the electrical signal, which carries image data concerning the object, to the signal processor. The signal processor receives the electrical signal, compares the image quality of the image data to its focus criteria, and generates a control signal, which it sends to the micromirror array lens to adjust the focal length of the micromirror array lens. This interative process is continued until the quality of the image data meets the focus criteria, and the process is completed within the afterimage speed of the human eye.

Abstract: The outer space laser speedometer is designed to be carried aboard a space vehicle either manned or unmanned for the purpose of measuring its speed through space by comparing the wave front angles of two separate laser beams at a 90 degree angle to each other and also in phase with each other, both light beams having been created by a single laser by means of a partially silvered mirror beam splitter or optic fibers diverting the light into two separate beams. Speed detection is accomplished by diverting both beams from their 90 degree angle back to parallel where they result in interference patterns which can be viewed through an eye piece or recorded with an electronic camera linked to a computer that calculates the pattern drift into speed.

Abstract: Titled "Graham Power, A New Method of Generating Power" inventor David Graham.    Graham power is a power plant. In its simplest form, it is an air conditioning /refrigerant system which also produces power. This is accomplished by adding a turbine to an air-conditioning system.  The evaporation process extract heat from the air and the turbine converts that heat into power. In fact it is a power generating system. Graham Power recycles the very fuel that it uses. Graham Power does not consume fuel nor does it release CO2 gas to the environment. It simply draws heat from the surrounding air and transforms it into useful power. In the process of extracting heat from the environment it cools the air. This cooling effect is beneficial to the atmosphere which is currently overheating.

Abstract: The subject application relates to a gas arrestor system(s) and/or methodology that facilitate sensing and shutting down a gas-burning appliance via a circuit that can perform both functions. In particular, the system and method can detect specific gases and at specific concentration levels by way of a sensory-power circuit. The circuit performs vapor detection and provides power to various ignition-related portions of the appliance. When gas or gas vapors are detected in the ambient air of the circuit and satisfy a threshold for that particular type of vapor, the circuit is shorted which results in a power loss to at least the ignition--related portions of the appliance. As a result, undesirable ignition of such vapors is mitigated.
