Memos - A Mobile Extensible Memory System

Memory disturbances are a frequent outcome of brain damages. Maintenance or enhancement of the pa- tients' life quality requires an enormous eort of caregivers or family members. To support patients with brain injuries the mobile distributed care system named MEMOS (Mobile Extensible Memory System) was designed, implemented and tested in the daycare clinic for cognitive neurology at Leipzig University. MEMOS is implemented as a distributed sys- tem, using CORBA technologies and Enterprise Java Beans. A special palmtop computer, the Personal Memory Assis- tant (PMA), reminds the patient of important tasks and supervises the patients actions. The PMA communicates with the stationary care system via a bidirectional cellular radio connection. The stationary care system was developed under the angle of dependability and scalability and the as- pect of unreliable cellular phone connections to the mobile device. This paper describes the design and function of the MEMOS system as well its application to the practical care of patients.
