Abstract: The invention describes compounds, compositions, and methods of using the same comprising a chemical moiety covalently attached to amphetamine. These compounds and compositions are useful for reducing or preventing abuse and overdose of amphetamine. These compounds and compositions find particular use in providing an abuse-resistant alternative treatment for certain disorders, such as attention deficit hyperactivity disorder (ADHD), ADD, narcolepsy, and obesity. Oral bioavailability of amphetamine is maintained at therapeutically useful doses. At higher doses bioavailability is substantially reduced, thereby providing a method of reducing oral abuse liability. Further, compounds and compositions of the invention decrease the bioavailability of amphetamine by parenteral routes, such as intravenous or intranasal administration, further limiting their abuse liability.

Abstract: A circuit for improving transient response for a load coupled to a voltage regulator by employing both load current level information and the regulator's output voltage to control a loop that provides relatively faster and accurate regulation of the regulator's output voltage. The circuit includes an error amplifier that is coupled to a reference voltage and feedback resistors connected to the regulator's output voltage. This error amplifier outputs a compensation signal that is subsequently summed at a summing point with additional information regarding the amount of current flowing through the load. Then, this summed compensation signal is subsequently employed by a pulse width modulation (PWM) comparator and other components to regulate the regulator's output voltage with improved speed and accuracy. The circuit can be arranged in different topologies, including buck, boost, and buck/boost.

These nanofibers can be assembled and integrated, and the assembled or integrated association or structure can realize various shapes.

Abstract: A projected on-time (POT) switching regulator is provided. The regulator includes a switching regulator controller and a main switch. The controller includes a feedback comparator and an on-timer. The feedback comparator compares the output voltage to a reference voltage. Whenever the feedback comparator trips, the main switch is turned on, and the on-timer controls the turn-on duration (on-time) of the main switch, where the duration is adjusted by the input and output voltages according to a preset transfer function. The transfer function is applicable to both CCM and DCM operation. However, during CCM mode operation, at least above a minimum on-time, the on-time is adjusted so that the switching frequency of the regulator is approximately constant. The on-timer includes a comparator that compares an adjustable voltage VFQ to a ramp voltage VIFQ generated by providing an adjustable current IFQ to a capacitor CREF.
