An analyte monitor includes a sensor, a sensor control unit, and a display unit. One side of the flexible substrate is used to mount the discrete components, while the remaining side of the flexible substrate comprises a releasably-adherent surface that allows the display device to be releasably mounted to an external receiving surface. User identification data, inclusive of all operator IDs and owner IDs correlated to the data processing device, are stored in a storage device each time image data is captured by the data processing device. The depot-to-depot plan module may be configured to compute a depot-to-depot transportation plan for packages transferred between the origin depot and a destination depot. The current starved inverters are controlled by a single voltage, which causes the current starved inverter’s delay to degradeimprove on only one transition to effect a change in the duty cycle.
