The interface may include a universal serial bus interface and may be coupled to a data isolation chip and a power isolation chip. A power controlling processor may determine how the supplied power, e.g., voltage, is supplied to other components within the infusion device. Additional circuitry within the system may provide a secure power transfer within the device to ensure user safety and ensure that a high frequency noise is properly attenuated. ## Claims ### Claim 1 An ambulatory infusion pump, comprising: a housing having a front surface and a back surface that are spaced apart and enclosed by side surfaces to define an internal cavity; an electrical connector port fitted to the housing and extending into the internal cavity, the electrical connector port operably connected to a power isolation integrated circuit chip and a data isolation integrated circuit chip disposed within the housing, the electrical connector port adapted to receive electrical power and data via a direct electrical connection, and direct the electrical power to the power isolation integrated circuit chip and the data to the data isolation integrated circuit chip; and wherein the housing and electrical connector port provide a seal preventing passage of moisture into the internal cavity. ### Claim 2 (depends on 1) The ambulatory infusion pump of claim 1, further comprising an electrical connector port door configured to be attached to the housing over the electrical connector port. ### Claim 3 (depends on 2) The ambulatory infusion pump of claim 2, wherein a seal is formed between the electrical connector port and the electrical connector port door. ### Claim 4 (depends on 3) The ambulatory infusion pump of claim 3, further comprising an overmold formed around the power isolation integrated circuit chip and in contact with the electrical connector port that provides the seal between the electrical connector port and the electrical connector port door. ### Claim 5 (depends on 4) The ambulatory infusion pump of claim 4, wherein the overmold is comprised of a non-conductive material. ### Claim 6 (depends on 1) The ambulatory infusion pump of claim 1, wherein the power isolation integrated circuit chip is electrically isolated from the data isolation integrated circuit chip. ### Claim 7 (depends on 1) The ambulatory infusion pump of claim 1, further comprising: a processor disposed in the housing;
