摘要:
Data indexing using polyarchical indexing codes and automatically generated expansion paths. For a piece of data, an indexing code is received relating to a particular categorization or other indexing parameter. Based upon the indexing code, one or more expansion sets of codes are retrieved and applied to the piece of data. The expansion sets of codes may include indexing codes that relate to hierarchical levels of indexing. The expansion sets of codes may also include different expansion paths through the hierarchical levels of indexing. The polyarchical codes may include multiple cross-categorization of the data across the same or different levels of categories. They may also include multiple expansion paths in different directions across hierarchical levels of categories or indexing.
摘要:
A device for irrigating soil has a chassis having wheels or tracks for motion, the chassis having one or more water sprinklers with streams directed at the soil, a water storage tank, and a sloped catchment surface having one or more sloped planes or curved surfaces for receiving water from a refill station into the water storage tank, wherein, under the control of an electronic circuit, the irrigation device can refill the water tank by positioning any part of the catchment surface under a water stream from the refill station. A method has the steps of measuring soil moisture at remote locations, refilling the mobile robot using a gravity feed water stream, defining a route for distribution of water, traversing the irrigation routes, refilling water according to soil moisture measurements, storing photovoltaic energy in a battery, and rotating, to a compass heading such that the photovoltaic array is optimally oriented.
