Abstract: Disclosed is a waterproof shoe with an improved ventilation mechanism, designed to circulate air from the outside environment through the shoe in order to provide convective cooling to a wearer's foot. In a desired embodiment, the shoe may incorporate a pump-ventilation mechanism which, coupled with airflow channels incorporated in the upper, acts to establish continuous substantially one-way airflow through the shoe in a heel-to-toe direction while a user walks.

Abstract: A variety of devices for protecting a user's foot from injury are disclosed. In one instance, the device is an external metatarsal protection device for a shoe or boot, having a sole with a first surface for supporting a wearer's foot and a second surface for contacting a ground area, an upper affixed to the sole, and an integral toe cap. An interior surface of the upper and the first surface of the sole define a receptacle for receiving the wearer's foot. The external protection device is incorporated along an exterior surface of the upper and is positioned to protect at least a metatarsal region of the wearer's foot. In an instance, the external protection device has injection-molded first and second layers of material, with the cushioning elements formed on a surface of the first layer and a plurality of grooves defined on a surface of the second layer.

Abstract: A system and method for managing form-generated data related to a patient encounter involves translating location information related to a user writing on a form into a contextualized data element that includes contextual information. The contextual information helps to explain and/or give meaning to the user writing. Contextual information may include a descriptive name, an identification of data type, healthcare classification information, taxonomic information, an indication of the patient, an indication of the person that wrote on the form, and/or an indication of the date and time at which the writing occurred. The contextual information is then used by an Electronic Medical Record (EMR)/Electronic Health Record (EHR) application to perform a function such as patient/insurance billing, case management, or order fulfillment.

Abstract: A method for optimizing the performance of a time-critical computation component for a real-time interactive application includes the use of an algorithm having a precise logical thread and at least one fast estimation logical thread. The computation errors generated by the fast estimation thread are imperceptible by humans and are frame specific such that the errors are corrected within a graphical frame's time by the data from the precise logical thread.
