Abstract: Patients with substance abuse problems may be prescribed regular medication that dulls the positive effects of the substance. However, one of the largest challenges for substance abuse patients is that many do not regularly take their medication as they want to experience the high of the substance. Accordingly, systems and methods have been developed for medication sessions that distract the patient from taking the medicine by incorporating the reminder and other med actions in close temporal proximity.

Abstract: A method of and apparatus for accelerating data retrieval on a widely dispersed content distribution network such as the World Wide Web. The system associates a concept URI with a resource which can then serve as a reference for a group of resources. When the system receives a request from a client calling for a resource in this group, it prepares a delta encoded responses based on the difference between the reference document and the response it has obtained from an origin server (the identity response). The system then sends the client the delta encoded response, an identification of the reference document used to prepare the delta encoded response, and an address where the reference document may be obtained if a client does not already have a copy.
