Abstract: The present disclosure relates to a fuel-air premixer for a turbine system. The fuel-air premixer includes a swirler and a centerbody. The swirler is configured to direct a flow of air through the premixer, and the centerbody is configured to inject fuel into the flow of air. Additionally, the centerbody includes an airfoil shape that reduces and/or substantially eliminates recirculation pockets to prevent autoignition and/or flame holding in a combustion chamber. Accordingly, the turbine system may produce fewer NOx emissions.

Abstract: This disclosure describes systems, methods, and apparatus for reducing power consumption and improving performance on a computing device. A method includes scheduling, with a driver on the computing device, one or more activity times that indicate when the driver will be active and storing the one or more activity times that indicate when the driver will be active. When a request to suspend a system of the computing device is received, the stored activity times are accessed to identify when the driver will be active, and a determination is made whether any of the one or more activity times is scheduled to occur within a suspend time window. If the driver will not be active during the suspend time window, suspension of the system is initiated.

The punch can be removed, a powder precursor of the second cap loaded onto that surface, the first punch assembled to the die, and a third pre-load applied to form a third pre-pressed structure. The third pre-pressed structure can be sintered to form the thermoelectric material; the first or second cap can be coupled to an electrical connector.

Abstract: During a storage redundancy giveback from a first node to a second node following a storage redundancy takeover from the second node by the first node, the second node is initialized in part by receiving a node identification indicator from the second node. The node identification indicator is included in a node advertisement message sent by the second node during a giveback wait phase of the storage redundancy giveback. The node identification indicator includes an intra-cluster node connectivity identifier that is used by the first node to determine whether the second node is an intra-cluster takeover partner. In response to determining that the second node is an intra-cluster takeover partner, the first node completes the giveback of storage resources to the second node.

Abstract: Systems and methods for improved implementation of low power modes in a multi-core system-on-a-chip (SoC) are presented. A cache memory of the multi-core SoC not being accessed by other components of the SoC is identified and a number of dirty cache lines present in the cache memory is determined. For a low power mode of the core, an entry latency based on the number of dirty cache lines is determined, and an exit latency is determined. An entry power cost for the low power mode is also determined based on the number of dirty cache lines A determination is made whether the low power mode for the cache memory results in a power savings over an active mode for the cache memory based at least on the entry power cost and the entry latency of the cache memory entering the first power mode.

In one embodiment, data associated with user of viewing interactive infomercial content may be received on a mobile viewing device.

Abstract: A printed quasi-tapered tape helical element and printed helical array antenna. The helical element comprises a thin helix conductor having a uniform section associated with a tapered section. The helix conductor can be printed on a thin dielectric sheet and bonded to a hollow composite dielectric support. A solid copper conductor is configured to provide electrical connection between a feeding point of the helix conductor and a microstrip line of a microstrip feed network. The uniform and tapered helix turns are respectively wrapped around the uniform and tapered sections, which enables impedance matching, axial mode excitation, gain and radiation patterns, and damping out of standing waves generated in current distribution over the helix conductor. Conductive composite cups surrounding each helical element reduces mutual coupling in array environment. Thus, the helical element and the array antenna achieve low on-axis and off-axis axial ratio performance over the wideband for global coverage.

Abstract: A dynamic cache extension in a multi-cluster heterogeneous processor architecture is described. One embodiment is a system comprising a first processor cluster having a first level two (L2) cache and a second processor cluster having a second L2 cache. The system further comprises a controller in communication with the first and second L2 caches. The controller receives a processor workload input and a cache workload input from the first processor cluster. Based on processor workload input and the cache workload input, the cache controller determines whether a current task associated with the first processor cluster is limited by a size threshold of the first L2 cache or a performance threshold of the first processor cluster. If the current task is limited by the size threshold of the first L2 cache, the controller uses at least a portion of the second L2 cache as an extension of the first L2 cache.
