20140334643 | DIGITAL MICROPHONE DEVICE WITH EXTENDED DYNAMIC RANGE - The present disclosure refers to a digital microphone device providing a single-bit Pulse Density Modulation PDM output signal. The digital microphone comprises a microphone, arranged to convert an acoustic input signal into an analog electrical signal, and a preamplifier, having a variable gain, arranged to receive the analog electrical signal and to provide an amplified analog electrical signal, depending on the variable gain. The variable gain depends on a gain control signal. The digital microphone further comprises an Analog-to-Digital Converter block, arranged to receive the amplified analog electrical signal and to convert it into a respective digital signal; and a compensation block, arranged to receive the digital signal and to perform a digital operation on such digital signal, on the basis of a compensation signal, to generate a compensated signal. Furthermore, the digital microphone comprises an Automatic Gain Controller block | 11-13-2014 |

20150033413 | GRF3 Mutants, Methods and Plants - The present disclosure provides a novel modified gene, rGRF3, or an orthologue thereof, which is shown to be decoupled from control by miR396, particularly in the presence of over-expression of at least one GIF gene, such as GIF1, AtGIF 2, AtGIF 3, Os11g40100, Os12g31350, Os03g52320 or combinations thereof. When present in a plant, the rGRF3 results in a phenotype of increased productivity (e.g. increased yield, increased biomass, increased stress resistance, increased seed production, increased seed yield, increased root growth, increased root elongation speed, delayed leaf senescence or increased drought tolerance and combinations thereof). | 01-29-2015 |
