  • Patent number: 11222723
    Abstract: The invention relates to a method and system that uses ultra-high frequency (UHF) radio frequency identification (RFID) for counting and identifying a variety of objects during medical or surgical operations. The method includes passive UHF RFID tag, a RFID scanner to communicate with host equipment and storage in a database cloud. The method includes a water-proof antenna and microchip supported by a substrate with covering overlay materials. The invention further discloses a tracking method for counting process, with software implementation, to assist the count-in count-out function to track multiple medical devices, resulting in reduction of counting errors during surgical procedures when the current UHF RFID process is utilized.

  • Publication number: 20060143007
    Abstract: An iterative process is provided for interacting with a voice information service. Such a service may permit, for example, a user to search one or more databases and may provide one or more search results to the user. Such a service may be suitable, for example, for searching for a desired entity or object within the database(s) using speech as an input and navigational tool. Applications of such a service may include, for instance, speech-enabled searching services such as a directory assistance service or any other service or application involving a search of information. In one example implementation, an automatic speech recognition (ASR) system is provided that performs a speech recognition and database search in an iterative fashion. With each iteration, feedback may be provided to the user presenting potentially relevant results. In one specific ASR system, a user desiring to locate information relating to a particular entity or object provides an utterance to the ASR.
