20090102547 | FLYBACK CURRENT CONTROL - One embodiment of the invention includes a power driver system. The power driver system comprises a power transistor that is activated to provide power to a load and a switching circuit configured to control the power transistor based on a control signal. The power driver system further comprises a control circuit configured to detect a flyback current from the load upon deactivation of the power transistor and to cause the switching circuit to steer the flyback current from a first flyback current path to a second flyback current path in response to detecting the flyback current path. The second flyback current path can have an impedance that is greater than the first flyback current path. | 04-23-2009 |

20100264981 | CHARGE PUMP WITH SELF-TIMING AND METHOD - With conventional charge pumps, significant noise is present due at least in part to large changes in the supply current. To combat this problem, a charge pump is provided that includes a number of stages. These stages are coupled to receive periodic alternating voltages having a phase shift with respect to each other so that the changes in the supply current are reduced, which reduces noise. | 10-21-2010 |

20100148875 | CIRCUIT FOR COMPENSATION OF LEAKAGE CURRENT-INDUCED OFFSET IN A SINGLE-ENDED OP-AMP - An electronic device includes an operational amplifier, with the operational amplifier having an amplifier input stage coupled with a first output node to an amplifier output stage. A compensation capacitance is connected between an output node of the amplifier output stage and the first output node of the amplifier input stage, thereby operating as a compensator for stabilizing the operational amplifier. The compensation capacitance provides a parasitic diode drawing a first leakage current from the first output node of the amplifier input stage, a leakage current compensation circuit being coupled to the first output node of the amplifier input stage and coupled to a second output node of the amplifier input stage for drawing a first current from the first output node and a second current from the second output node. The leakage current compensation circuit is adapted such that the second current is greater than the first current by an amount corresponding to the first leakage current. | 06-17-2010 |

20100037673 | APPARATUS AND METHOD FOR MONITORING TANKS IN AN INVENTORY MANAGEMENT SYSTEM - A method includes lowering a sensor unit in a tank, where the tank is capable of receiving a material. The method also includes determining a first distance between the material and the sensor unit and determining a second distance between the sensor unit and a main unit that lowers the sensor unit. In addition, the method includes determining a level of the material in the tank using the first and second distances. The method could further include calibrating the sensor unit to compensate for variations in a medium within the tank, where the sensor unit transmits wireless signals through the medium to determine the first distance. Determining the first distance could include using an ultrasonic measurement technique, and determining the second distance could include using a non-contact servo measurement technique. | 02-18-2010 |
