Abstract: An improved user interface and query method permits a computer user to quickly specify field names, operators, and desired values for a database query. One or more of the desired values can be specified as an “ask me” value that will cause the user to be prompted (each time the query is to be executed) for a desired value prior to executing the query. A “wizard-like” set of dialog boxes guides the user through prompts to supply values for all such “ask me” values in a compound query. Rather than presenting the user with arcane logical operators and a formalistic query language, logical operators are converted into ordinary English phrases. The user can save the query for later re-use or modification. Another feature prompts the user with a constrained list of possible values that a field can assume, forcing the user to select from among the constrained values rather than requiring the entry of a discrete value.

Abstract: A cat litter box with a mechanism for screening and draining reuseable, liquid-impervious granular material contained in the box, the box having a housing with a container, the container having an inner compartment with holes for holding the granular material and draining liquids, and an outer compartment for receiving drained liquids, the inner compartment having a screen, wherein the mechanism both raises the screen through the granular material to separate solid wastes, and tips the container to drain the liquid wastes and separated solids into a collection box for removal, and lowers the container, returning the screen to the inner compartment and redistributing the granular material over the screen before the container seats in the housing for reuse.
