Abstract: An electrowinning cell for extracting metals from an electrolyte solution, the electrowinning cell comprising a housing, a solution inlet, a solution outlet, a plurality of anodes, a plurality of cathodes and a product outlet, wherein at least one anode is substantially impermeable and configured to maintain a gap between a lower edge of the anode and the housing, so that fluid flow of solution is directed below the anode, and wherein at least one cathode is secured at a lower edge to the housing to prevent fluid flow below the lower edge of the cathode.

Abstract: The present invention is a system and method for handling location information. The goal of the present invention is to allow users to collect and evaluate information from multiple sources, and thus make proper use of all available location information. Location sources for the present invention include mobile electronic devices such as mobile telephones, cell phones, hand-held computers, personal digital assistants, pagers, Global Positioning System (GPS) devices, and other pervasive computing devices. Satellite-based or network-based positioning technologies make it possible to determine the geographic location of these wireless electronic devices and their users (e.g. location-based services for users of mobile telephones use such positioning technologies). Location sources for the present invention also include computer-based models, schedules or calendars that give a person's expected location depending on the date and time.

Abstract: Provided is a system and method that acquires and aggregates information to determine the location of a user. Information from multiple sources is collected and evaluated. Location sources include mobile electronic devices such as mobile telephones, cell phones, hand-held computers, personal digital assistants, pagers, Global Positioning System (GPS) devices, and other pervasive computing devices. Satellite-based or network-based positioning technologies make ti possible to determine the geographic location of these wireless electronic devices and their coresponding user. Location sources also include computer-based models, schedules or calendars that gave a particular user's expected location depending on the date and time. Provided is a method for aggregating information to determine a user's location. Also provided is a system for executing the claimed method. Also provided is a service for providing the claimed method.

Abstract: A method, apparatus, and computer instructions for synchronizing a database used by a client device with at least one server. A locally unique identifier is associated with each record in the database at the client. The locally unique identifier for a deleted record is changed to a selected value. This value is selected in a manner to indicate that a record has been deleted. This locally unique identifier may be a negative value and may be selected by multiplying the locally unique identifier by a negative one. The selected value is used in synchronizing the database and is used to track records deleted since a last synchronization of the database. In the depicted examples, this selected value is unique and allows for mapping back to the locally unique identifier for the record.

Abstract: A method, apparatus, and computer instructions for synchronizing a database utilized by a client device with a set of servers in which one server has the database. A change log is used with a client database for synchronizing the database. Dirty bits set in the client database are identified and a change log is modified based on the identified dirty bits. This change log is used to synchronize the database on the server with a client database on the client device.
