The communication module 172 facilitates communication with other devices via one or more external ports 122, and it also includes various software components for processing data received by the RF circuitry 120 and/or the external ports 122.

In some embodiments, the touch module 174 may selectively detect contact with the display system 160 or other touch-sensitive device (e.g., touch buttons, touch pads). For example, the touch module 174 in conjunction with the display controller 140 detects contact with the display system 160. The touch module 174 includes various software components for performing various operations associated with detection of contact (which may be by a finger or stylus, etc.) by the display system 160, such as determining whether contact has occurred (e.g., detecting finger press time), determining the strength of contact (e.g., force or pressure of contact), determining whether the contact has moved (e.g., detecting one or more finger drag events), tracking movement on a display screen, or determining whether the contact has ceased (e.g., detecting finger lift time or contact break). The operation in which the movement of the point of contact is determined may include determining a velocity (magnitude), a velocity (magnitude and direction), and/or an acceleration (including magnitude and/or direction) of the point of contact. These operations may be applied to single point contacts or multiple simultaneous contacts. In some embodiments, the touch module 174 in conjunction with the display controller 140 detects contact by other touch devices.

The touch module 174 may be used to detect gesture input by a user. Different gestures by the user on the touch-sensitive device have different contact patterns (e.g., one or more combinations of locations, times, or intensities at which contacts are detected). For example, detecting a single-finger tap gesture includes detecting a finger-down event and then detecting a finger-up event at the same or a similar location as the finger-down event. For example, detecting a finger swipe gesture on the surface of the touch device includes detecting a finger-down event, then monitoring for one or more finger-dragging events, and then detecting a finger-up event. Similarly, taps, swipes, drags, and other gestures of the stylus are optionally detected by detecting a particular contact pattern of the stylus.

The tactile feedback module 176 includes various software components for generating instructions to produce tactile outputs at one or more locations of the infusion pump 100 using one or more tactile output generators (not shown) in response to user interaction with the infusion pump 100. For example, after detecting contact with the surface of the touch device, the color of the graphics or text of the touch device changes, or sound or vibration is generated.

The location module 180 includes software components for performing various operations related to detecting device location and detecting changes in device location.

Graphics module 182 includes various known software components for rendering or displaying graphics on a display screen of display system 160 or other external device, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual attributes) of the displayed graphics. In embodiments herein, the term "graphics" includes any object that may be displayed to a user, including without limitation text, web pages, icons (e.g., user interface objects for soft keys), digital images, videos, animations, and the like. In some embodiments, the graphics module 182 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The graphic module 182 receives one or more codes for specifying a graphic to be displayed from an application program or the like, and also receives coordinate data and other graphic attribute data together if necessary, and then generates screen image data to output to the display controller 140.
