  • Publication number: 20190336682
    Abstract: A drug delivery system is provided. The drug delivery system can include a drug delivery device configured to store and deliver a drug to a user and a drug delivery management device for managing operation of the drug delivery device. The drug delivery management device can determine information relating to the drug that is to be provided to the user. The information relating to the drug can be provided by an indicator coupled to a container configured to store the drug. The drug delivery management device can determine a software program for controlling operation of the drug delivery management device based on the determined information relating to the drug. Other embodiments are disclosed and described.

  • Patent number: 8924911
    Abstract: Circuit simulation can be performed on digital, analog, and mixed signal types of circuitry. Phases of operation are identified for a circuit and transient behavior is analyzed. Multiple time points are identified and the circuit is replicated for those time points with evaluation of the circuitry performed at those various time points. Simultaneous optimization is performed across the time points. Transistors and other devices can have their lengths, widths, and number of fingers optimized. Simulation can include determining Kirchhoff current law equations for various nodes within the circuit. Equations describing device operation can include non-convex signomial equations and convex polynomial equations.

  • Publication number: 20080077890
    Abstract: Methods for optimizing design parameters of a circuit are disclosed. In one aspect, an optimization problem includes one or more performance specifications that represent an exponent of a design parameter to be optimized. Various parameters of passive and active circuit devices may be efficiently and accurately optimized as a result. In another aspect, linear performance specifications are included for accurately calculating voltages. In yet other aspects of the invention, three special types of convex optimization problems are disclosed for enabling the above use of exponents of design parameters which provide efficient and accurate calculations of a virtually unlimited array of circuit parameters and performance characteristics.
