Flat panel display technologies for portable and personal information systems are reviewed. The display sub-system performance requirements, and the metrics for evaluating display technologies for portable systems are discussed. The current display technology choices for high performance portable systems are active matrix liquid crystal display (AMLCD) and field emitter display (FED). AMLCD is at the forefront at an advanced state of development, and it is already in mass production for notebook computer applications. Because of the huge market size, AMLCD technology continues to be developed at an aggressive pace to address the needs of the future portable systems. On the other hand, FED technology is not currently in mass production, but it is being developed at rapid pace; Impressive technology capabilities and demonstration displays have already been shown. This review focuses on the current status and future development trends in both the these display technologies for application to portable systems. The current status of the reflective LCDs and their future development trends are also reviewed. 相似文献

The aim of this paper is to introduce the main software module of the DIABCARD Chip Card Medical Information System (DIABCARD CCMIS) that provides an online, portable diabetes medical record information system based on a high performance object-oriented rapid application development language such as Borland Delphi. A chip card based medical information system was developed as a good possibility to create a portable electronic patient record. In particular the patient data card makes the up-to-date patient's record available whenever needed. The developed DIABCARD Core System, described in this paper, includes a patient record management system that has the ability to handle topics such as administrative and medical data, medical anamnesis, and physical examination data. Issues tackled were simplicity, data security and reporting, customization, and internationalization. Especially for the two last issues (customization and internationalization) a novel approach based on using native initialization table files is presented. Proper care has been addressed during the development of the software modules for matters of security, data integrity and confidentiality. 相似文献

Recent studies conclude that early and specialized prehospital management contributes to emergency case survival. We have developed a portable medical device that allows telediagnosis, long distance support, and teleconsultation of mobile healthcare providers by expert physicians. The device allows the transmission of vital biosignals and still images of the patient from the emergency site to the consultation site using the GSM mobile telephony network. The device can telematically “bring” an expert specialist doctor to the site of the medical emergency, allow him/her to evaluate patient data, and issue directions to the emergency personnel on treatment procedures until the patient is brought to the hospital. Legal reasons mandated the inclusion at the consultation site of a multimedia database able to store and manage the data collected by the system. The performance of the system has been validated in four different countries using a controlled medical protocol and a set of 100 patients per country treated has been collected and analyzed 相似文献
