3. Ubiquitous Computing
Coined by weiser
“ubiquitous computing” as “access anytime
anywhere”
enhancing computer use by making many
computers available throughout the physical
environment, but making them effectively invisible
to the user

4. Introduction
Paper discuss about two embedded systems
Ubiquitous Echograph
Networked digital camera
Hospital Information System
Computational servers processing EMRs
Innumerable terminals
Information networks
Medical device embedded into hospital which is a
gigantic computer system

5. Ubiquitous Echograph
Echograph
Sensing unit
Computation unit
Display unit
embed the medical device by simply replacing the
bus with the information network supporting the
HIS

6. Continued..

7. Continue..
Working
Mobile probe obtain echo signal ,send it via wi-fi
Server software reconstruct echogram and send to
display
Advantages
Increases mobility of doctor
No need to move patients
Decreases maintenance cost

8. Prototype of Ubiquitous Echograh

9. Two types of sensors
Mechanical scan 1-D echo probe
Compress resampled echo signal by LZ-77 compression
Generate B-mode images
SonoSite SonoHeart Echograph

11. Networked digital camera
Digital camera
Charge-coupled device(CCD)
Storage(PACS)
Display
system can be embedded by replacing bus with
LAN of HIS

13. Working
Photos taken by camera
Stored in temporal server
After QA process confirmed photos stored in PACS
To smoothen the process HIS use barcode to
identify the patient

14. The system works as a state machine

15. Prototype of networked digital camera

16. Continued..
Clinician set camera to barcode reading mode
Take barcode of clinician and patient
Check in QA interface
Confirmed photos are sent to PACS

17. Commercial networked digital camera

18. Continued..
System utilizes Eye-Fi to connect to network
checks all incoming images and recognize patient
id by barcode
Following images stored to patients temporal
folder
Finally confirmed images are stored

19. Conclusion
proposed to embed medical device, a small
computer system, into HIS, a gigantic computer
system.
