The Pentominos Patient Registration System

The patient registration system handles the pairing of a patient, an operator and an apparatus at a given location at a given time interval.
This is necessary in order to correctly store the produced data in a way that makes it possible to retrieve it at a later point in time, for further analysis.
The system consists of five basic units:

1. A system A is used by a nurse that binds the patient with an UID, for the day.
2. The Pidio¹⁾ client that retrieves UID from an external reader, and sends it to the Pidiod server, together with its location ID.
3. The Pidiod²⁾ server that:
   • Handles the maps between UID to patient ID.
   • Handles the maps between location ID to UID.
4. The Feed³⁾ data retrieval client that makes the actual apparatus communication.
5. The Artefact data server.

The system works in the following steps:

• The patient arrives.
• The patient identifies him or herself at the desk, by patient ID.
• The patient ID is connected with an UID in the Pidiod server, using A.
• The patient is given a RFID tag containing that UID.
• The patient is sat down in front of an apparatus.
• The operator identifies him or herself to the Pidio client (by using a similar UID).
• The patient identifies him or herself to the Pidio client.
• The operator performs the measurement at the apparatus.
• The apparatus somehow sends its data to the Feed data retrieval client.
• The Feed data retrieval client sends its preconfigured location ID to the Pidiod server.
• The Pidiod server responds with the patient and operator ID.
• The Feed data retrieval client sends the retrieved data, alongside the preconfigured apparatus ID, the newly retrieved patient and operator IDs, a timestamp and its preconfigured location ID, to the Artefact dataserver.
• … jump back to step The patient is sat down in front of an apparatus. and cycle until done …
• The patient optionally returns the RFID tag when leaving.

Currently we have a running implementation of all systems but A (hence the non-name). The current implementation of Pidio utilizes a simple numerical keyboard and a magnetic strip reader, for danish health insurance card.
To improve simplicity on the system, no identification is currently made of the operator (this is at the time being not mission critical data, but must be added at a later point due to documentation procedures) Documentation of all communication protocols between the systems exists but are not yet written in a formal way. These documents will be produced A.S.A.P.

We suggest that a new Pidio implementation is created based on the RFID technology, reusing the rest of the patient registration system.
In order to make it more 'sexy' it is essential that the reader itself is given a sturdy look-and-feel design.
The application A must be designed as a GUI application (and named properly) and implemented at least as a working prototype.
