Abstract: A lidar photosensor amplification circuit may include light sensors; amplifiers corresponding respectively to the light sensors, in a powered-on state, to amplify output signals of the respective light sensors as amplified outputs; and switches corresponding respectively to the amplifiers, where individual switches may be controlled to pass a respective amplified output in a closed state or disconnect the amplified output in an open state. The lidar photosensor amplification circuit may be controlled by a controller according to timing rules that conserve power supplied to photosensor amplification circuit, reduce heat produced by the light sensor board, and do not aggravate cross-talk between sensors. The timing rules include staging an amplifier for a staging time before the corresponding light sensor is to be read, closing a switch after the staging time has passed, and powering down the amplifier and opening the switch after a reading time passes.

Abstract: An apparatus for translating a series of source words in a first language to a series of target words in a second language. For an input series of source words, at least two target hypotheses, each comprising a series of target words, are generated. Each target word has a context comprising at least one other word in the target hypothesis. For each target hypothesis, a language model match score comprises an estimate of the probability of occurrence of the series of words in the target hypothesis. At least one alignment connecting each source word with at least one target word in the target hypothesis is identified. For each source word and each target hypothesis, a word match score comprises an estimate of the conditional probability of occurrence of the source word, given the target word in the target hypothesis which is connected to the source word and given the context in the target hypothesis of the target word which is connected to the source word.
