Abstract: A system for betting on fractional times comprises a memory coupled to a processor. The memory stores a first betting option comprising a bet that a particular participant in a race will finish a predetermined length of the race in a first range of fractional times. The memory further stores a second betting option comprising a bet that the particular participant in the race will finish the predetermined length of the race in a second range of fractional times. The processor receives a plurality of bets on at least one of the first betting option and the second betting option and determines an actual time for the particular participant to finish the predetermined length of the race. The processor then determines which of the plurality of bets are winning bets based at least in part upon the determination of the actual time and the corresponding betting options.

Abstract: The disclosure below describes a knowledge pattern machine that goes beyond and is distinct from a traditional search engine as simple information aggregator. Rather than acting as a search engine of the data itself, the knowledge pattern machine use variously layers of artificial intelligence to discover correlations within the queries and historical data, and to derive and recognize data patterns based on user queries for predictively generating new knowledge items or reports that are of interest to the user. Previous patterns and knowledge items or reports are accumulated and incorporated in identification of new data patterns and new predictive knowledge items or reports in response to future user queries, thus providing a stateful machine. The predictive knowledge items are updated in real-time without user interference as the underlying data sources evolve overtime.

Abstract: A two-sided casing chisel has two chisel blades that are mirror images of each other to enable one tool for chiseling and cleaning the doorway casing on either side of the doorway. The two-sided tool simply has to be flipped around to allow cleaning of doorway casing on an opposing side of the doorway. The chisel blades may be coupled to a blade assembly that is detachably attachable to a handle assembly. The blade assembly may have a first end and second end each having a two-sided chisel blade or sanding ends with an abrasive material to allow sanding along a doorway casing. The blade assembly may be reversible to allow a user to flip the blade assembly upside down to expose second end which may have sanding ends for sanding or a second set of chisel blades in the event blades on the first end become dull.

Abstract: A computer system automatically organizes, retrieves, annotates and/or presents media data files as collections of media data files associated with one or more entities, such as individuals, groups of individuals or other objects, using context captured in real time from a viewing environment. The computer system presents media data from selected media data files on presentation devices in the viewing environment and receives and processes signals from sensors in that viewing environment. The processed signals provide context, which can be used to select and retrieve media data files, and can be used to further annotate the media data files and/or other data structures representing collections of media data files and/or entities. In some implementations, the computer system can be configured to be continually processing signals from sensors in the viewing environment to continuously identify and use the context from the viewing environment.
