Abstract: A system for generating a schema representation in a dynamic schema database is provided. At least one processor is configured to identify an initial schema for a target grouping of source data and execute a query to identify source data documents not matching the initial schema. The at least one processor captures attributes from non-matching documents and generates an updated schema by performing a union operation of the initial schema and captured attributes. The at least one processor iteratively re-executes the query to identify documents not matching the updated schema and updates the schema based on attributes from non-matching documents. The at least one processor validates the updated schema when no results are returned from a query identifying non-matching documents.

Abstract: A disrupter unit is used for explosive ordnance disposal by firing a slug into the ordnance to be destroyed. A method is shown to secure the disrupter unit to a sand bag or other stationary location during such firing of the disrupter unit. The present invention may also adapt the disrupter unit to shear wire, such as barbed wire, by attaching a wire cutter element to the disrupter unit through a robust cable during firing. Likewise, the disrupter unit may be used as a remote pull device or further to unearth a buried item via mechanical advantage, wherein a military shovel or another long rod is attached by a robust cable to the disrupter unit.
