Abstract: Example approaches for associating relevant tags for facilitating searching and extracting relevant medical documents, are described. In an example, a document characteristic field of the documents extracted from a database repository are tagged with tag values to obtain a tagged document. Thereafter, the tagged document is stored in the database repository. To search the tagged document, a target value for the document characteristic field is obtained and compared with the tag values of the tagged documents. Based on the result of comparison, a list of tagged documents is extracted from the database repository and displayed for user's review.

Abstract: A method is disclosed for generating data encoded RF (radio frequency) waveform without a separate memory device/chip. The hardware in the proposed method consists of entities performing the operations of time-delay (B), phase shifting (C), attenuation, power dividing (D) and power combining (E). An integral part of the invention is the application of the the method in designing radio frequency identification devices or RFID-tags.
