  • Publication number: 20180288147
    Abstract: Methods and systems are provided to manage display of cardiac signals. The methods and systems receive a first data steam along a first communications path conveyed with first throughput and receiving a second data stream along a second communications path transmitted with second throughput. The first and second throughputs are asynchronous with respect to one another. The first and second data streams carry cardiac signals sensed by external and implanted electrodes, respectively, for one or more common events. The methods and systems store data from the first and second data streams in first and second memory buffers. The methods and systems synchronize the data stored in the first and second memory buffers with one another by performing at least one of: temporally offsetting activation of the storing operation for the first and second data streams with respect to one another; or managing an amount of the data maintained in at least one of the first memory buffer or the second memory buffer.

  • Publication number: 20180104153
    Abstract: An automatic medicine retrieving device includes a medicine tray, a medicine box, and a driving mechanism. The medicine tray includes a bearing plate defining an exit port and a medicine separating member rotatably positioned on the bearing plate. The medicine separating member has medicine separating areas and a positioning area. Medications in the form of pills are positioned on the bearing plate and received in the medicine separating areas. The medicine box is opposite to the exit port. The driving mechanism drives the medicine separating member to rotate from being opposite to the exit port, bringing the medicine separating area to a position opposite to the exit port. A pill in the medicine separating area then passes through the exit port to fall into an accepting mechanism.

  • Publication number: 20180078777
    Abstract: A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.
