Abstract: A network device that can be implanted in a subject is described. The device is configured to communicate over a computer network. In one embodiment, the device of the invention includes an internal interface in physiological communication with the subject. The internal interface is coupled with, and configured to send signals to, a processor. The processor is configured to receive and process the signals, and is further configured to communicate over a computer network with another such device. Such devices can be used to monitor and communicate information regarding a host's physiological status, monitor and/or control artificial organs and prosthetic devices, and/or dispense medication.

Abstract: The present invention comprises a method for providing feedback to the user of a graphical user interface using visual and operational clues. In an embodiment of the invention, the user is provided visual clues that inform the user in what direction the display area can be scrolled. The display area may contain a list, a text box, a pop-up menu or any kind of data. Operational clues help the user determine what actions move the list and what actions do not move the list. The invention can be implemented in the form of a list. A list is comprised of one or more fields. At the top of the list and at the bottom of the list is a blank space that functions as one of the visual clues. The purpose of the blank space is to inform the user they are at the top of the list and cannot scroll any further up or that they are at the bottom of the list and cannot scroll any further down. Another form of visual clue is provided through the use of partially visible fields.
