Abstract: An overshoe that is removably disposable on a user's shoe and provides a tread surface that enhances the user's footing on slippery surfaces. The tread surface has removable spikes that penetrate surfaces and forward-oriented and rearwards-oriented gripping ridges that grip the surface. The ease of pulling on and removing the overshoe is enhanced by using stretch zones that are placed to allow stretching of the overshoe to fit over a shoe or the like without compromising the snugness of the overshoe fit. A spike assembly for use with an overshoe that fits over a person's shoe and enhances a person's contact with the ground, includes a spike having a head operably coupled to a shank; and a button overmolded on the spike and having a neck for removable engagement in a bore defined in the overshoe.

Title: Server agent system
Inventor: DATTATRI KAYSHAV
IPC: G06F11/34
Filed: 2000-05-11
Granted: 2009-07-14
Abstract: A server agent system that provides agents, transmitted to a server by a client, that monitor specific event(s) on the server. When a pre-defined event(s) occurs, an agent performs a set action(s) in response to each event. The actions are pre-defined by the client. The agent requires no further intervention of the client once it is placed on the server and are created by a client or news reader and, when created by a news reader, agents are treated as a value added service provided by the application. The types of actions that an agent performs can be almost anything that the client desires and include the execution of Java and/or Javascript programs which are supplied by the client or the server. An agent's events and actions are subject to the same access control security restrictions as the client that submitted the agent. The types of agents available on a server are pre-defined and are supplied as agent templates and are building blocks for the client to build agents with. A server can only supply agents that it understands and publishes the available agent templates and events on an agent home page where clients select from the list of agent types available on the server and submit an agent to the server. Servers also provide administration services for clients with resident agents where they monitor and manage their agents on the server. Each agent is assigned a unique identifier and token by the server. Names can also be assigned to an agent by the client. Server administration are provided with an administration function to maintain and manage agents resident on that server. Agent objects are created on the server that uniquely identify that agent which is mapped to the proper event and is triggered upon occurrence of that event. When the agent is triggered, its action list is processed, executed and agent information and statistic are logged.

Abstract: The invention relates to a transmit diversity method for a wireless communication system comprising a transmitting element and at least one receiver, wherein a transmission signal is transmitted from the transmitting element to the at least one receiver in accordance with a weight information determined in response to a feedback information.      The feedback information is derived from the response at the at least one receiver to the transmission signal, and is fed back using multiplexed feedback signals.      Multiple feedback signal quantization constellations and/or constellation specific feedback subchannels can be used for channel probing, such that the total feedback resolution and robustness can be enhanced, while maintaining low signaling capacity of the feedback channel.

Abstract: A method and coating are provided for temporarily protecting a substrate or article during shipping, handling or storage by applying a removable protective coating over at least a portion of the substrate. The substrate may be flat or curved and may have zero, one or more functional coatings. A plurality of substrates with the protective coating of the invention may be arranged in a shipping container so that the protective coating reduces the possibility of damage to the substrate or optional functional coating.  In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. In another embodiment, the protective coating is formed by sputtering a substantially carbon coating onto the substrate. The carbon coating is subsequently removed by combustion. The protective coating may have identification materials, such as colorants or fragrance materials, such that different types of substrates and/or functional coatings can be distinguished from each other. Additionally, the temporary protective coating can improve the heating of a functionally coated glass substrate.

Title: Coating an aluminum alloy substrate
Inventor: GUTHRIE JOSEPH D
IPC: C23C26/00
Filed: 1999-11-03
Granted: 2006-07-04
Abstract: An alluminum alloy substrate is pretreated with an aqueous solution containing an organophosphorus compound, preferably a vinylphosphonic acid-acrylic acid copolymer, before coating the substrate with a polymer. Passing the substrate through the solution contaminates it with aluminum and other elements. The pretreatment solution is rejuvenated by removing aluminum with a cation exchange resin that preferably contains a styrene-divinyl benzene copolymer functionalized with sulfonate groups. Rinsing the substrate contaminates the rinse water with the copolymer. The rinse water is concentrated by reverse osmosis or membrane ultrafiltration and retured to the pretreatment solution.
