Abstract: The current document is directed to methods and systems for automated generation of evaluation and management medical codes (“E/M codes”). In one implementation, a series of processes are applied to a medical document in order to generate annotations and concepts, extract metadata, and, using the annotations and concepts, and, in certain cases, the extracted metadata, to generate a set of feature/feature-value pairs that parametrically represent the contents of the medical document. Models for E/M codes and E/M-code components are generated to contain sets of weights, each weight corresponding to a feature for which a feature-value is automatically generated from medical documents. These weights are used as multipliers, in certain implementations, of the feature values generated for a medical document. Multiplication of feature values by corresponding weights produces terms that are used to generate scores for each of various different E/M codes.

Abstract: A unique, multi-cartridge, easily re-configurable ambient air filter assembly (air contaminant control system) that removes particulate and gaseous chemical/biological contaminants from the incoming cathode air stream on a fuel cell or similar devices is described. The filter assembly is composed of individual filter cartridges (sub-assemblies) of various filtration media that are targeted at removing specific airborne contaminants. Combining specific sets of cartridges enables the filter assembly to be readily/rapidly configured (and re-configured) for specific applications—such as urban, rural, industrial, or military battlefield environments. Selection of correct media ensures complete removal of potential contaminants, enables rapid re-configuration to different environments, quick replacement of spent cartridges without disposal of non-spent media (reducing waste and cost).
