  • Publication number: 20170003908
    Abstract: A memory system comprises a memory controller and a memory device having one or more memory ranks and multiple memory electrically connected to the one or more memory ranks. The memory controller includes at least one analysis module and at least one switching determination module. The analysis module analyzes states of multiple memory control commands corresponding to a particular memory rank to generate a control parameter. The switching determination module determines whether at least one switching command is sent according to the control parameter, a current operation mode of the particular memory rank, and an operation state of the particular memory rank. When the memory device receives a first switching command of the at least one command, the particular rank and at least one part of the memory internal circuits are switched from the normal voltage operation mode to the low voltage operation mode.

    Abstract: A fluid heat exchange apparatus including a casing, and a heat-dissipating device is provided. The casing includes a chamber, an inlet, and an outlet. The chamber includes a first channel including a first entrance and a first exit and a second channel including a second entrance and a second exit. The cross-sectional area of the first channel decreases from the first entrance to the first exit and the cross-sectional area of the second channel decreases from the second entrance to the second exit. The heat-dissipating device is located between the first exit and the outlet. A first fluid flows from the inlet and flows through the first channel and the heat-dissipating device and then flows to the outlet. Part of the first fluid flowing through the heat-dissipating device absorbs heat and forms bubbles moving to the second channel and then forms a second fluid converging into the first channel.

  • Publication number: 20160258691
    Abstract: A heat dissipation module including an evaporator, a copper tube communicated with the evaporator to construct a loop, and a heat-transmitting medium flowing in the loop is provided. The evaporator includes an upper cover and a lower cover connected with each other and constructing a cavity. The lower cover has a heat-isolating wall protruded toward the cavity, so as to separate a heat-isolating region and a heating region at the lower cover. The upper cover has a slope inclining toward the cavity. A heat of an electronic element is transmitted to the heat-transmitting medium through the heating region, so that the heat-transmitting medium flows out of the evaporator towards a single direction along the slope after absorbing the heat, flows in the copper tube to transmit the heat outward through the copper tube, and then flows back to the evaporator through the copper tube after dissipating the heat.

  • Publication number: 20160209980
    Abstract: A process determines touch orientation of touches on a sense array of a touch-sensing device. The process obtains first touch data and second touch data of a conductive object proximate to the sense array at two temporally proximate times. The first and second touch data are then used to determine a first touch orientation, and the second touch data is used to determine a touch area and a provisional touch orientation. A touch orientation change is then determined as an absolute difference between the first touch orientation and the provisional touch orientation. The touch orientation change is compared with a threshold change, and the touch area is compared with a threshold area. In accordance with comparison results, the first touch orientation, the provisional orientation, or a weighted combination of them is designated as a second touch orientation corresponding to one of the two temporally proximate times.
