In one embodiment, a medication dispensing device of a system for controlling and monitoring medicine dispensation includes means for securely containing a medication to be dispensed to a specific patient, means for confirming an identify of the patient, means for determining whether or not the patient is eligible to receive a dose of the medication at a time the dose is requested, and means for dispensing the dose of medication only if the patient's identity is confirmed and the patient is eligible to receive the dose.

A power state management system of an electronic system is coupled to a plug load device and a method for operation of the same. The system includes a context clock to adjust a duty cycle of the electronic system for controlling the power states of the electronic system for more efficient use of electricity. The context clock is responsive to user input, multiple event driven activities or an external protocol determined policy or command. Interface circuitry communicates user input, multiple event driven activities or an external protocol determined policy or command to the context clock. Interface circuitry also communicates commands to the managed plug load device or devices.

Devices, systems and methods for delivering pre-determined quantities of an active ingredient to a biological system are provided. In various embodiments, a device for controlled release of an active ingredient is provided, including a release aperture operably associated with a deflectable member, a base with a porous membrane substrate layer, and at least one chamber juxtaposed between the release aperture and the porous membrane layer. The chamber may contain a matrix including one or more active ingredients and an agent that expands when contacted with an aqueous solution. The device is suitable for implantation in a biological system and can be used for delayed and/or time release of specific drug dosages for various indications.

A low loading capacitance on-chip electrostatic discharge (ESD) protection circuit for compound semiconductor power amplifiers is disclosed, which does not degrade the circuit RF performance. Its principle of operation and simulation results regarding capacitance loading, leakage current, degradation to RF performance are disclosed. The design, loading effect over frequency, robustness over process and temperature variation and application to an RF power amplifier is presented in detail. The ESD circuit couples an input to ground during ESD surges through a diode string coupled to the input, and a transistor switch or Darlington pair having its gate coupled to and triggered by the diode string. The Darlington pair couples the input to ground when triggered through a low impedance path in parallel to the diode string. A reverse diode also couples ground to the input on reverse surges.

A micropump fabricated in a planar substrate is provided with a valving chamber which is communicated to a pumping chamber. The valving chamber has an inlet and outlet port. Both the valving chamber and pumping chamber have a liquid, electrically conductive piston disposed therein, which liquid piston is nonmiscible with the pumped working fluid and nonreactive with the substrate in which the chambers are formed. The valving piston is magnetohydrodynamically driven to selectively close either the inlet port or the outlet port. The pumping piston is magnetohydrodynamically driven to pull or push the working fluid through one of the inlet or outlet ports, through the valving chamber, into the pumping chamber, back out of the pumping chamber and through the other one of the inlet or outlet ports after activation of the valving piston. Both direct current and inductive magnetohydrodynamic drives are contemplated. The valving and/or pumping chambers may be shaped or narrowed in their dimensions to impose a mechanical bias on the respective valving and/or pumping pistons to assume a preferred position in their respective chambers when the magnetohydrodynamic drive is turned off.
