  • Publication number: 20210105840
    Abstract: Devices, systems and methods are provided to improve pairing between two devices by employing an inductive antenna circuit (e.g., 13.56 MHz) in addition to another wireless communication antenna circuit (e.g., 2.4 GHz) and a pairing protocol to minimize pairing between unintended devices. Communications via inductive antenna circuit (e.g., 13.56 MHz) require that the devices to be paired to be in close proximity to each other, which increases the likelihood of intended pairing between these devices. When the inductive pulses of the first device are detected by the second device, the second device commences advertising signals with time stamps. The inductive pulses and the time stamps facilitate synchronizing scanning windows of the first device with the advertising signals of the second device to lessen the likelihood of interference of advertising pulses from an unintended device.

  • Publication number: 20200384190
    Abstract: A medical device controller is provided that avoids unintended user inputs and unwanted medical device operation(s). A controller sends display commands to a graphical user interface (GUI) display to generate a first screen having a swipe field with no moving icons that prompts a user to initiate a designated operation by the medical device. When a valid swipe gesture is inputted, the controller generates a second screen with confirm button that requires a valid user press before the controller undertakes the designated operation, the controller generating and sending a command for the designated operation to the medical device when the controller determines that a valid user press has been inputted to the confirm button. The controller also sends commands to generate a status screen that transitions a rotating progress ring symbol and level indicator in accordance with a selected event to clearly indicate the status of medical device operations.
