Abstract: A method of preparing an aqueous dispersion of opacifying polymer particles containing inorganic pigment particles therein is disclosed. The method yields hollow polymer particles containing pigment particles therein using a non-RAFT emulsion polymerization process by free radical polymerization. The technique is much faster and simpler than known RAFT methods.

Abstract: Providing context to a target minimizes the amount of information that a user must input. Context transfer pages receive context and reformat for the target. Selection of links to such pages provide context which is then reformatted and provided to the target to pre-populate information for the user. A return link can be specified to enable the target to return further context upon user interaction completion. The return link can specify further context transfer pages which can use the returned context to direct the performance of convenience actions, including invoking other applications on the user's computing device and entering information into them. The context transfer pages can themselves collect information from the user to provide appropriate interfaces without requiring resource investment from the target.

Abstract: To accommodate different types and versions of execution environments on mobile devices, requests for applications from a programmable device, such as a smart phone or other mobile device include status data about the characteristics of the device. Information about the display, memory, storage, and/or script engine may be forwarded with a request. At a fulfillment server, the information is evaluated so that an appropriately versioned and configured application can be custom built, or selected from a pre-built inventory of applications. This allows a user to postpone an upgrade and still receive appropriate versions of executable, optimized to the particular mobile device.

Abstract: A method of managing software issues includes receiving issue data from a remote host, where the issue data is related to an issue associated with a software application installed on the remote host. The method identifies a potential solution for the issue and sends solution data to the remote host, where the solution data is related to the identified potential solution. Feedback data may be received from the remote host, where the feedback data is indicative of a degree to which the identified potential solution was effective in resolving the issue.

Abstract: An environmentally friendly stable aqueous optionally structured water-resistant architectural coating composition (especially a paint) containing a film-forming binder polymer composed of a starch modified by the presence of carboxylic acid or inorganic carboxylate groups and bonded (probably grafted) to chains of copolymerized mono-ethylenically unsaturated monomers (e.g. “acrylic”, “vinyl” or “styrenic” copolymers) permitting a stable aqueous dispersion of the binder polymer to be made which retains good water-resistance in the dried paint. The modified starch allows paints to be made with less dependence on materials obtained from non-renewable resources whilst retaining a low water-sensitivity.
