Abstract: Quiescent currents in a circuit that includes a regulator are reduced by disabling selected portions of the circuit. A window comparator is selected activated to evaluate the input voltage such that a first operating mode is activated when the input voltage is within a predetermined voltage range and a second operating mode is activated when the input voltage is outside of the predetermined voltage range. The battery voltage is used a reference signal when the first mode is selected such that a voltage reference circuit can be disabled to reduce power, while the voltage reference circuit is enabled when the second mode is selected. Another comparator circuit is periodically activated to compare the reference signal to the output voltage. The regulator is disabled after the output voltage exceeds a first level. The output voltage collapses below a second level associated, the evaluation and regulation process is repeated.

Abstract: A method for a modified “Washers” tossing game are revealed. The method includes using modular panels with slots, colored washers, and stakes. Using the kit, a simple or complex course consisting of different target areas can be constructed. Sample rules for the new game are also disclosed.

Abstract: A switching regulator circuit is arranged to provide a constant current to a load. The switching regulator circuit is operated in discontinuous current mode such that an inductor stores energy in a first part of an oscillation cycle, and discharges in a second part of the cycle. The trigger mechanism for the oscillator is disabled when the charged inductor couples energy to the load, and enabled after the inductor is detected as discharged. The energy stored in the inductor is proportional to the square of the on-time associated with switching regulator. Constant voltage load devices such as LEDs for a display can be driven by the switching regulator in an open-loop mode such that the current in the load devices is a linear function of the on-time.
