Abstract: A puzzle with letter placeholders coupled with a plurality of arrow indicia. The arrow indicia may be disposed to associate at least a first letter of the letter indicia with a second letter, thus associating the first letter and the second letter to form a portion of, or a complete word spelled with the first and second letter. Further disclosed is a method to make a puzzle including identifying a first word in a language, said word including a plurality of letters; identifying one or more subwords of the first word; associating the letters of the first word and subwords, said associating including the ordering of letters in the first word and subwords, and presenting an image of the puzzle, with a placeholder for each letter in the first word and a connecting links representative of the order of letters in the first word.

Abstract: Discussed generally are techniques for managing operation of programs in a sequential order. A method can include receiving a query for an image, the query indicating characteristics of the image, selecting a chain of algorithms configured to identify the image based on the characteristics, operating an algorithm of the selected chain of algorithms that operate in increased fidelity order on an input to produce a first result, operating a ground truth algorithm on the input to generate a second result, comparing the first and second results to determine a probability of correctness (Pc) and confidence interval (CI) for the algorithm, and altering the chain of algorithms based on the determined Pc and CI.

Abstract: A battery interface module is provided that includes a housing and a battery interface carried by the housing and configured to interface with a battery. The battery interface may include a first power bus interface, a first fluid interface and a first data interface. The battery interface module may also include first and second transmission interfaces carried by the housing. At least one of the first and second transmission interfaces may be configured to interface with another battery interface module. Each transmission interface may include a second power bus interface, a second fluid interface and a second data interface. Additionally, the first and second power bus interfaces may be in electrical communication, the first and second fluid interfaces may be in fluid communication and the first and second data interfaces may be communicably connected.

Abstract: A modular and hierarchical multiple bus computer architecture in which the master bus and slave bus are substantially identical, and communicate through a combination of an interface controller and a shared dual port RAM responsive to a shared RAM controller. Processor engine modules including a bus, a processor, an interface controller, a shared dual port RAM, and a shared RAM controller are horizontally and/or vertically integrated at multiple levels without major restructuring of the composite system control operations by having each slave processor engine module interface as a peripheral upon the bus of its master. The modularity of the architecture allows the use of standard peripherals and platform processor engines to expand memory or increase functionality without burdening the master bus processor engine. Each slave bus processor engine is fully functional as an independent processor with mastery over its own bus.
