Abstract: A rehabilitation footwear device for assisting in controlling weight application to an injured lower appendage includes a shoe that is configured to position around and reversibly couple to a foot of a user. A control module that comprises a power module and a microprocessor is coupled to the shoe. The microprocessor is operationally coupled to the power module. A plurality of sensors is coupled to and positioned in a sole of the shoe. The sensors are operationally coupled to the microprocessor. The sensors are configured to measure pressure applied to the sole from the foot that is positioned in the shoe and to relay a pressure measurement to the microprocessor. A speaker is coupled to the shoe. The speaker is operationally coupled to the microprocessor. The microprocessor is positioned to compel the speaker to emit an audio alert should the pressure measurement exceed a threshold limit.

Abstract: Methods, systems, and computer program products for determining an expected value of generating an agency debit memo and/or inquiry, scheduling a task of generating the memo and/or inquiry, and determining optimal operator staffing levels. An optimizer module determines if an agency debit memo should be generated based on a probability the memo will be disputed by a travel agency and the expected value of generating the memo, and whether an inquiry should be generated in response to the dispute. Tasks of generating agency debit memos and inquiries are ranked and scheduled based on benefit density to optimize the cumulative net return for a given operator staffing level. Data is collected on execution of the tasks and ultimate outcomes and used to determine operator efficiency and to update expected value parameters. Optimum staffing levels may be determined by performing virtual task scheduling for different staffing levels.
