  • Publication number: 20160220773
    Abstract: A laryngeal mask airway is provided. The laryngeal mask airway mainly includes a handle. A front end of the handle is connected to a mask body, and the handle and the mask body are formed of a flexible polymer material (e.g., polyvinyl chloride, PVC) for medical use. A guiding hole is formed at a side where the mask body and the handle are connected, and a working area is formed at an external opening of the guiding hole. With the working area, after an endotracheal intubation procedure is completed, a medical staff is able to hold the endotracheal tube with fingers throughout the whole procedure when the laryngeal mask airway is being removed, to prevent an improper movement of the endotracheal tube.

  • Publication number: 20150339611
    Abstract: A system, and computer program product for minimizing undesirable user responses in automated business processes design are provided in the illustrative embodiments. A user response is identified in an interaction between a user and an automated business process. Using sentiment analysis, a determination is made that the user response comprises an undesirable response based on an undesirable emotional state of the user. A modification is selected, wherein the modification causes a change in the interaction to minimize the undesirable response. The modification is applied to the automated business process to cause the change in a future portion of the interaction.

  • Patent number: 9125032
    Abstract: A method, system, and computer program product for caching data in a cellular network is provided. Information from a cellular network regarding location, speed, direction of travel, and bandwidth for a user can be used to determine how much data should be cached for the user. More specifically, the time period for how long a user will be in a cell of a cellular network can be calculated using information received from the cellular network. The calculated time period can be used to calculate how much data will be used by a user for the calculated time period with only the amount of data needed for the time period being cached.

  • Patent number: 8897766
    Abstract: The present invention is a method and system that reduces the amount of data traffic across communication links in a cellular network. In this system, the cellular device of a user receives and stores state information about a byte of data. During the implementation of the method of this invention, when a user desires to retrieve data from the Network Core, tokens containing a description of the state information for the requested data are sent to the cellular device. The cellular device can then have these tokens resolved by a Node B cell site that has stored the requested data. This approach reduces the need to resend the data from the Network Core over communications links. Further, the cellular devices can freely move from cell site to cell site with little interruption or loss of information.
