Abstract:The monitoring and treatment of patients in a care unit is a complex task in which even the most experienced clinicians can make errors. A hemato-oncology department in which patients undergo chemotherapy asked for a computerized system able to provide intelligent and continuous support in this task. One issue in building such a system is the definition of a control architecture able to manage, in real time, a treatment plan containing prescriptions and protocols in which temporal constraints are expressed in various ways, that is, which supervises the treatment, including controlling the timely execution of prescriptions and suggesting modifications to the plan according to the patient’s evolving condition. The system to solve these issues, called SEPIA, has to manage the dynamic, processes involved in patient care. Its role is to generate, in real time, commands for the patient’s care (execution of tests, administration of drugs) from a plan, and to monitor the patient’s state so that it may propose actions updating the plan. The necessity of an explicit time representation is shown. We propose using a linear time structure towards the past, with precise and absolute dates, open towards the future, and with imprecise and relative dates. Temporal relative scales are introduced to facilitate knowledge representation and access.

Abstract A network-based real-time control architecture has been developed which integrates a haptic interface (the Sarcos Dextrous Arm Master) with an advanced CAD modeling system (Utah’s Alpha_1). New algorithms have been developed and tested for surface proximity testing, fast updates to local closest point on a surface, and smooth transitions between surfaces. The combination of these new algorithms with the haptic interface and CAD modeling system permits a user to actively touch and manipulate virtual parts as well as passively view them on a CRT screen.
