| 20090061369 | Multi-response time burner system for controlling combustion driven pulsation - A combustion system having at least one wall enclosing a combustion chamber and forming a plurality of burner or burner nozzle openings. Disposed within each of the openings is a premix burner or burner nozzle, each of which has a premixed fuel/oxidant outlet proximate the combustion chamber and a fuel/oxidant inlet distal from the combustion chamber. At least a portion of the premix burners or burner nozzles are sized to produce different fuel/oxidant delivery disturbance response times in response to a pressure disturbance within the combustion system. Differences in fuel/oxidant delivery response times are achieved by using burners or burner nozzles having different internal dimensions, different volume flow rates, and, optionally, by varying the fuel/oxidant ratios of the mixtures flowing through the burners or burner nozzles. | 03-05-2009 |

| 20090153242 | METHOD AND APPARATUS FOR DIRECT DIGITAL TO RADIO FREQUENCY CONVERSION - A method and apparatus for direct conversion of digital data to high power RF signals, known as DDRF. The method and apparatus receive a digital signal, create a digital modulated signal therefrom, and amplify the modulated signal with an H-bridge Power Amplifier for transmission. DDRF uses a multi-level H-bridge amplification circuit to establish a more power efficient digital transmitter. | 06-18-2009 |
| 20100001701 | CIRCUIT WITH ONE OR MORE DEPLETION MODE TRANSISTORS - An H-bridge circuit formed from two sub-circuits coupled to each other by a load network across a respective load node of each of the sub-circuits. Each sub-circuit of the two sub-circuits comprises a depletion mode upper transistor with a second electrode coupled to a first electrode of a lower transistor. The load node of the sub-circuit is disposed between the second electrode of the upper transistor and the first electrode of a lower transistor. There is a first voltage supply node coupled to a first electrode of the upper transistor and a second voltage supply node is coupled to a second electrode of the lower transistor. An upper driver transistor selectively couples a gate electrode of the upper transistor to an upper drive voltage node, the upper driver transistor having a control electrode coupled to an upper switched voltage supply circuit. There is also a lower switched voltage supply circuit coupled to a gate electrode of the lower transistor and a voltage dependent non-linear resistor is coupled across the gate electrode and second electrode of the upper transistor. In use, when the lower transistor and upper driver transistor are in a non-conductive state a potential difference across the voltage dependent non-linear resistor is sufficiently small enough to control the upper transistor into a conductive state. Conversely, when the lower transistor and upper driver transistor are in a conductive state the potential difference across the voltage dependent non-linear resistor provides a negative bias to the gate electrode of the upper transistor that has a negative potential sufficient to control the upper transistor into a non-conductive state. | 01-07-2010 |

| 20090147440 | LOW INDUCTANCE, HIGH RATING CAPACITOR DEVICES - Methodologies and structures are disclosed for providing multilayer electronic devices having low inductance and high ratings, such as for capacitor devices for uses involving faster pulsing and higher currents. Plural layer devices are constructed for relatively lowered inductance by relatively altering typical orientation of capacitors such that their electrodes are placed into a vertical position relative to an associated circuit board. Optionally, individual leads may be formed so that the resulting structure can be used as an array. Internal electrodes may be arranged for reducing current loops for associated circuits on a circuit board, to correspondingly reduce the associated inductance of the circuit board mounted device. Leads associated with such devices may have added tab-like structures which serve to more precisely place the lead, to improve the lead to capacitor strength, and to promote lower resistance and inductance. Disclosed designs for reducing associated inductance may be practiced in conjunction with various electric devices, including capacitors, resistors, inductors, or varistors. | 06-11-2009 |

| 20100267867 | BLENDS OF BIODEGRADABLE POLYMERS AND ACRYLIC COPOLYMERS - The invention relates to a blend of one or more biodegradable polymers with one or more acrylic copolymers, for the purpose of improving the properties of the biodegradable polymer(s). The biodegradable polymer contains at least 10 weight percent of a biopolymer that is in less than ideal condition for processing. The “compromised” biopolymer may be undried biopolymer, may have a heat history (be “reprocessed”, “regrind” or “recycled”), or both. The acrylic copolymer(s) are present in the blend at a level of 0.1 to 15 weight percent, based on the weight of the total blend. | 10-21-2010 |

The biodegradable polymer is preferably a polylactide or polyhydroxy butyrate. The composition comprises 30-99.9 weight percent of degradable polymer and 0.1 to 15 weight percent of one or more impact modifiers. | 04-07-2011 |
