20130332111 | GENERATING INFORMATION CONDITIONAL ON MAPPED MEASUREMENTS - Processing a measurement includes receiving a first set of at least one measurement. The first set of at least one measurement is processed to generate conditional information corresponding to the first set of at least one measurement. The processing includes: generating a plurality of possible samples, each possible sample representing a sample from a prior probability distribution, mapping at least each measurement in the first set, and each possible sample, according to a nonlinear mapping procedure, into corresponding vectors in a target space, and generating the conditional information according to an error probability density function that is based at least in part on differences between the mapped vectors in the target space. | 12-12-2013 |

20120062190 | DC-DC CONVERTERS - This application relates to switch mode DC-DC converter circuitry having a power switch operably connected between a supply node and an inductor node. The DC-DC converter has switch control circuitry for driving the power switch which is configured to controllably vary the rate of at least one of turn-on or turn-off of the first power switch. The rate may be based on the operational conditions of the converter, e.g. inductor current, one or more supply voltages and/or operating mode or activity level of a host device. By increasing the rate at which the switch turns-on or off switch transition power losses can be reduced. However a faster switching speed can lead to an increased voltage stress on the circuitry. Embodiments of the present invention varying the rate or turn-on and/or turn-off of the switch to reduce power losses but remain with the safe operating limits for the circuitry. | 03-15-2012 |
