  • Publication number: 20210207902
    Abstract: A droplet heat exchange system is provided for that includes a heat exchange chamber, at least one injector, and at least one swirler. The chamber is configured to have gas flow through it. The injector can be configured to dispense liquid droplets into the chamber for thermal energy exchange with gas flowing through the chamber. The swirler can disposed within the chamber and can have a body configured to form a spiral gas flow that pushes liquid droplets from the injector, radially outward as gas flows across the body, thereby separating the liquid droplets from the gas flowing across the body and forming a liquid film along an inner wall of the chamber. The collector can be in fluid communication with the heat exchange chamber and configured to collect the liquid film after thermal energy exchange. The collector can be configured to direct at least some of the collected liquid film to the injector for subsequent use.

  • Patent number: 9143132
    Abstract: Apparatuses including termination for complementary signals are described, along with methods for terminating complementary signals. One such apparatus includes a termination transistor including a first node configured to receive a first complementary signal and a second node configured to receive a second complementary signal. A regulation circuit can generate a regulated voltage to render the termination transistor conductive with a substantially constant resistance. In one such method, a first complementary signal is received at a drain of a termination transistor and a second complementary signal is received at a source of the termination transistor. Energy of the complimentary signals can be absorbed when the termination transistor is rendered conductive. Additional embodiments are also described.

  • Patent number: 8416628
    Abstract: Methods for sensing, memory devices, and memory systems are disclosed. In one such memory device, a local sense circuit provides sensing of an upper group of memory cells while a global sense circuit provides sensing of a lower group of memory cells. Data sensed by the local sense circuit is transferred to the global sense circuit over local data lines or a global transfer line that is multiplexed to the local data lines. An alternate embodiment uses the local sense circuit to sense both upper and lower groups of memory cells.

  • Patent number: 5511032
    Abstract: There is provided a memory array including columns of memory cells, source lines and bit lines. The memory array includes precharging apparatus which discharge selected source lines while pre-charging the array. Two embodiments of the pre-charging apparatus are provided. In both, the source lines are connected to a common bit line (CNBL) via groups of source pull-up transistors. The source lines are also connected to a source decoder. In one embodiment, the source decoder discharges selected ones of the disconnected source lines. In another embodiment, the source decoder both discharges selected ones of the disconnected source lines and connects the remaining disconnected source lines to the CNBL line.
