    摘要: Fluid-handling methods and devices for ultrasonic manipulation of fluid-borne particles comprise a fluid-handling manifold and an ultrasonic particle manipulator defining an ultrasonic cavity within the manifold. Fluid-borne particles introduced into the manifold are manipulated by controlling ultrasonic standing waves at the ultrasonic cavity. Cavities having non-uniform configurations, asymmetric standing waves and/or multiple ultrasonic cavities within the manifold are operative to control the movement of the fluid-borne particles, optionally including collecting and holding such particles, transferring particles through an intersection from one channel to another, etc. Solid phase extraction (SPE) particles, biological particles and other fluid-borne particles can be manipulated within the fluid-handling manifold.

    摘要: PPP frame encapsulation of IP frames—including FCS calculation, character escaping, and HDLC flag insertion—is performed by hardware acceleration circuits within a DMA module as part of a DMA transfer autonomously of a processor. Software may preprocess the IP packets prior to the hardware-accelerated processing. The hardware acceleration in the DMA module may additionally decapsulate PPP frames—including FCS calculation and comparison for error detection, escaped character recovery, and frame boundary detection—to assist in the formation of IP packets. The hardware-accelerated PPP framing may be particularly useful when a mobile terminal provides internet access, through a wireless communication network over packet data channels, to an attached peripheral device, such as a computer.

    摘要: Embodiments of a computer-implemented method of calculating estimates of a joint posterior probability of class membership given combinations of attribute values of a pair of attributes are disclosed. The calculating is performed on the basis of data representing a training set of a plurality of instances defined by attribute values for a plurality of attributes together with a class membership outcome. Embodiments of the method comprise calculating first and second estimates of a posterior probability of class membership given attribute values of a first and second attribute of the pair, respectively, and binning the first and second estimates into a respective plurality of first and second probability range bins. Instances of the training set are mapped to combinations of one of each of the first and second pluralities of probability range bins, and on the basis of the mapping, calculating estimates of a joint posterior probability of class membership.

    摘要: An integrated circuit includes a DMA controller for performing conventional DMA transfers and for backing-up and restoring data during low power events. The integrated circuit includes one or more processor components, one or more peripheral components, a power management circuit and the DMA controller. The power management circuit manages power control within the integrated circuit. The DMA controller includes a DMA engine for executing DMA transfers between different ones of the components and memory based on configuration parameters provided to the DMA engine. A detection circuit configured determines if the power management circuit initiates a power state change. The DMA controller also has circuitry for providing a first set of configuration parameters to the DMA engine if no change in power state is detected and overriding the first set of configuration parameters with a second set of configuration parameters if a change in power state is detected.
