The document discusses two embedded ubiquitous systems for hospital information systems: an ubiquitous echograph and a networked digital camera. The ubiquitous echograph replaces the echograph's bus with an information network, allowing the mobile probe to send echo signals to a server for image reconstruction and display. This increases doctor mobility and reduces costs. A prototype uses 1-D probes and compresses echo signals. The networked digital camera replaces its bus with the hospital LAN, taking photos identifiable by patient barcodes for quality assurance and storage to the patient file. A prototype uses Eye-Fi to connect to the network for automatic patient ID recognition and file storage. Both prototypes aim to embed medical devices into the hospital information system for anytime, anywhere access and use.
