  • Publication number: 20240120062
    Abstract: In one implementation, an insulin delivery system using an on-body network includes an insulin delivery device that is adapted to administer dosages of insulin to a patient; a controller that is adapted to control operation of the insulin delivery device, to establish a first network connection in which the controller acts in a central role, and to establish a second network connection in which the controller acts in a peripheral role; one or more peripheral devices that are adapted to generate patient data related to blood glucose levels and to transmit the patient data wirelessly over the first network connection, the peripheral devices acting in a peripheral role over the first network connection; and a mobile application installed on a mobile computing device that is programmed to communicate with the controller over the second network connection, the mobile application communicating in a central role over the second network connection.

  • Patent number: 5303042
    Abstract: An apparatus of the present invention includes a viewer response system comprising a host site and at least one remote site interconnected by a satellite channel for host-to-remote video, an X.25 communications channel for message exchanges establishing a virtual circuit between each remote and the host site, and a dial-up public phone network channel that allows the host site to dial a remote site in response to a person at the remote site wanting to speak on the system to another person at the host site. A touch screen monitor at the host site allows the other person to sequence through electronic notecards that function as presentation cue cards. Questions can be formatted on remote site monitors and keypad terminals for each person at each remote site to allow real-time responses to be entered. A computer supporting the host site computes and displays remote site status and person's responses.
