| 20100075347 | METHODS OF DETECTION USING ACOUSTO-MECHANICAL DETECTION SYSTEMS - Methods for detecting target biological analytes within sample material using acousto-mechanical energy generated by a sensor are disclosed. The acousto-mechanical energy may be provided using an acousto-mechanical sensor, e.g., a surface acoustic wave sensor such as, e.g., a shear horizontal surface acoustic wave sensor (e.g., a LSH-SAW sensor). The detection of the target biological analytes in sample material are enhanced by coupling of the target biological analyte (e.g., through the use of magnetic particles), application of a magnetic field to draw the target analyte to the sensor surface, and subsequent removal of the magnetic field before measuring detection. | 03-25-2010 |

| 20090015229 | Bi-directional DC power converter - A bidirectional power converter is presented. The power converter includes a circuit having a first and second power node and a first and a second internal node. Energy storage components are coupled between the power nodes and ground. A first switch is coupled between the first power node and the first internal node. A second switch is coupled between the first internal node and ground. A third switch is coupled between the second internal node and ground. A fourth switch is coupled between the second power node and second internal node. An inductive component is coupled between the first internal node and second internal node. A controller controls the switches in a manner such that power conversion occurs from the first to the second power node, from the second to the first power node, or power conversion is disabled and the power nodes are isolated from each other. | 01-15-2009 |
| 20090256539 | Circuits and Methods for Sensing Current - Embodiments of the present invention include techniques for sensing current. In one embodiment, a switch in a switching regulator is coupled to a power supply. Input current from the supply is translated into an output current of the switching regulator. A signal corresponding to the output current is generated. The signal is selectively turned off with the input switch is open. Accordingly, the signal tracks the input current into the regulator. The signal may be used to determine the input current. In one embodiment, the signal is a voltage signal generated by a current corresponding to the output current provided into a resistor. | 10-15-2009 |
| 20110018451 | Single Inductor Serial-Parallel LED Driver - An LED driver circuit is disclosed that can drive a plurality of LED strings that are arranged in parallel, each LED string having a plurality of component LEDs that are series-connected. The LED strings can be the same type of LEDs in each string, or have different types of LEDs from one string to another. The LED driver includes a voltage control loop that dynamically regulates the output voltage across the parallel arrangement of LED strings. The output voltage is dynamically adjusted to accommodate the LED string with the largest operational voltage drop. This enables LED displays to constructed using different types of LEDs strings, but still supply the LED strings in a power efficient manner. Further, each LED string also includes its own individual current regulation loop so that the current, and therefore brightness, of each LED string can be individually adjusted. | 01-27-2011 |
