  • Patent number: 8935753
    Abstract: A network based healthcare management system is provided. The system includes a plurality of client workstations and a plurality of healthspace service processors. The healthspace service processors access at least one database remotely disposed relative to the client workstations with the healthspace service processors providing access to predetermined healthspace resources. The system further includes a healthspace service interface unit operably coupled to the client workstations and healthspace service processors to selectively actuate at least one of the healthspace service processors responsive to the client workstations. The healthspace service interface unit including an efficiency module which adaptively maintains a plurality of parametric indicia with respect to optimum healthspace resource utilization.

  • Patent number: 8805759
    Abstract: A system and method are provided for psychographically profiling a target population of individuals, programmably implemented in a server apparatus. The psychographic segmentation portion includes a questionnaire processing part, a segment solution part, and a typing tool part. The questionnaire processing part acquires a plurality of responses to a predetermined set of questionnaire questions by an initial pool of target population members. The questionnaire processing part uses a combination of weighted statistical methodologies to arrive at a rule-based decision on whether the question would serve as a good wedge variable. Optionally, the rule based decision is then compared to an expert's opinion and the weights and threshold parameters of the weighted statistical combination are adjusted accordingly to more accurately match the expert's decision. The identified wedge variables are used for effectively segregating the target population into groups of homogenous individuals.
