20080320544 | HARDWARE-IMPLEMENTED VIDEO BROADCASTING RECEIVER - A hardware-implemented video broadcasting receiver is described. The hardware-implemented video broadcasting receiver includes a radio frequency (RF) tuner, a demodulator connected to the RF tuner, link layer logic connected to the demodulator, and a power manager connected to the RF tuner, the demodulator and the link layer logic. The power manager is configured to receive delta-T values extracted from a transport stream by the link layer logic, to determine whether each of the RF tuner, the demodulator and the link layer logic can be powered down based on the delta-T values, and to power down the RF tuner, the demodulator and the link layer logic based on the determination, thereby reducing the average power consumed by the video broadcasting receiver. | 12-25-2008 |

20150349563 | SMART VOLTAGE DEDICATED CHARGER SYSTEM - A voltage dedicated charger apparatus includes an AC-to-DC converter circuit, a pair of switches, and a controller block. The AC-to-DC converter circuit converts an AC input voltage to a DC output voltage. The pair of switches is operable to isolate a pair of data ports from the AC-to-DC converter circuit. The pair of data ports includes a DP port and a DN port. The controller block includes a monitor circuit, a transceiver, and a control circuit. The monitor circuit monitors the DP and DN ports of the apparatus. The transceiver receives one or more messages form a charge-receiving device and communicate data to the charge-receiving device. The control circuit controls operation of the pair of switches based on a signal from the monitor circuit. | 12-03-2015 |

20130323822 | Yeast Expressing Saccharolytic Enzymes for Consolidated Bioprocessing Using Starch and Cellulose - The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction. The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured together and used to produce ethanol from biomass feedstock. | 12-05-2013 |
