Merged Search Algorithms for Radio Frequency Identification Anticollision

Nowadays, the Radio Frequency Identification (RFID) system enables the control of many devices over an open communication infrastructure ranging from a small home area network to the global Internet. Moreover, a variety of consumer products are tagged with remotely low-cost readable identification electromagnetic tags to replace Bar Codes. Applications such as automatic object tracking, inventory and supply chain management, and Web appliances were adopted for years in many companies. The arbitration algorithm for RFID system is used to arbitrate all the tags to avoid the collision problem with the existence of multiple tags in the interrogation field of a transponder. A splitting algorithm which is called Binary Search Tree (BST) is well known for multitags arbitration. In the current study, a splitting-based schema called Merged Search Tree is proposed to capture identification codes correctly for anticollision. Performance of the proposed algorithm is compared with the original BST according to time and power consumed during the arbitration process. The results show that the proposed model can reduce searching time and power consumed to achieve a better performance arbitration

The Development of a Mobile Emergency Healthcare Information System in Taiwan

[[abstract]]Nowadays the quality of healthcare has been improved gradually. However, the time consuming pre-hospital emergency process could sometimes cause many regrets. Therefore, the minimization of time required for providing primary care and consultation to patients is one of the crucial factors when trying to improve the healthcare delivery in emergency situations. If the Emergency Medical Technician (EMT) can hold on signs of life of patients immediately when accidents happened, higher quality of healthcare could be achieved. Mobile healthcare is a new paradigm that combines the evolution of emerging wireless communications and network technologies to connect healthcare anytime and anywhere. The purpose of the study is to develop a Mobile Emergency Healthcare Information System (MEHIS). A Standard Operation Procedure of Emergency Healthcare (SOPEH) is first planned. Then, the system is developed for EMT or families of patients to communicate with physicians in hospitals. Users can use their 3G mobile phone to transfer symptoms and information of the situation to JSP server which then quickly delivers information while providing proper emergency care at the prime time. Meanwhile, MEHIS can shorten emergency healthcare time and therefore enhance quality of emergency healthcare
