Abstract: Described is a technology in which a platform unifies various social network and alerting mechanisms to provide a relationship-based communication network. An affiliation service allows organizations and individuals to connect, grant permissions and share useful information about themselves in the form of relationship-based and other attributes. A publishing service routes that information to the correct recipients, including by matching desired attributes to attributes of clients recipients. A data exchange service facilitates reporting, routing, monitoring and responding to such information, as well as providing relevant external data feeds to clients. In this manner, users and organizations are able to more easily connect and work together to resolve societal problems via a single platform that facilitates user and organizational participation.

Abstract: In one embodiment, in a power converter system having first and second switches connected in a half-bridge arrangement at a common node from which current flows through an inductor to a regulated output terminal, wherein the regulated output terminal is connectable to a load, wherein the first and second switches are turned on and off in cycles, a method is provided for synchronous rectification. The method includes: initiating a cycle in which the first switch is turned on; developing a timer based on the on-time of the first switch during the cycle; turning off the first switch and turning on the second switch during the cycle; and outputting a control signal to turn off the second switch when either the timer expires or a new cycle is initiated to turn on the first switch, thereby providing synchronous rectification in the power converter system.

Abstract: A heat exchanger for a compressor comprising a housing comprising a plurality of pass chambers, wherein each pass chamber comprises a plurality of tubes for contacting a hot fluid with a cooling media. At least one first flow nozzle introduces a first portion of the hot fluid into a first pass chamber. At least one second flow nozzle downstream of the first flow nozzle introduces a second portion of the hot fluid into at least one downstream pass chamber, forming a reduced rate of fluid flow in the first pass chamber and optimizing contact between the second portion of the hot fluid and the plurality of tubes, to form a cooled fluid. An outlet downstream of the second flow nozzle, in communication with a final pass chamber, is adapted for receiving the cooled fluid.

Abstract: Gas lift valve designs and gas lift systems are described that feature a positive closure mechanism that is highly resistant to significant wear or damage that would result in fluid leakage. A pivotable flapper member is incorporated into a gas lift valve and used as a flow control mechanism. The flapper member provides a positive barrier to fluid flow from the production tubing to the annulus, even after substantial wear or damage.

Abstract: A system for packaging a flat panel product includes a dispensing device for dispensing a length of inner protective packaging material, a folding table for wrapping the inner protective packaging material around the product and folding an outer protective packaging material around the product, and a binding device for binding the outer packaging material, inner packaging material, and product together, suspending the product relative to at least one of the walls of the sidewall and supporting the product laterally. A data entry device provides data related to the length of inner protective packaging material required, and this data is fed to a controller, which controls the dispensing device to provide an appropriate length of material. The data entry device can also provide shipping information, fed to a printer for printing a shipping label.

Abstract: A first prefetch engine from a first plurality of prefetch engines is allocated to a first load instruction in response to a buffer miss of an iteration of the first load instruction in a program stream. The first plurality of prefetch engines include prefetch engines for prefetching data from memory to a buffer based on a predicted stride. A second prefetch engine from a second plurality of prefetch engines is allocated to the first load instruction in response to the buffer miss. The second plurality of prefetch engines include prefetch engines for prefetching data from memory to the buffer based on an instruction loop representative of a sequence of instructions that affect an address value associated with an allocated load instruction. One of the first or second prefetch engines is deallocated if the other prefetch engine achieves a prefetch performance greater than a first threshold value.

Abstract: A program stream is executed at a first processing engine, the program stream including multiple iterations of a first load instruction. An instruction loop is executed at a second processing engine separate from the first processing engine substantially in parallel with an execution of the program stream at the first processing engine for prefetching data from memory to a buffer for one or more iterations of the first load instruction of the program stream. The instruction loop represents a subset of a sequence of instructions between iterations of the first load instruction that affect an address value associated with the first load instruction. A confidence value associated with the instruction loop is modified based on a prefetch performance of one or more iterations of the first load instruction and it is determined whether to terminate execution of the instruction loop based on the confidence value.

Abstract: One or more control lines or other types of lines can be run past a downhole tool such as a side pocket mandrel, for example, in a longitudinal groove with a retaining feature for the control line where the assembly leaves little to stick out and get damaged on run in or on pulling out of the hole. In the preferred version, the groove is a dovetail and at least one retainer can be slipped into the dovetail. Lateral bores into the dovetail allow pins to be driven into a wedge shaped retainer to force it against the control line or lines such that the shape of the dovetail and the shape of the wedge retainer trap the control line within the dovetail. Upon assembly, nothing sticks out from the dovetail or the downhole tool.

Abstract: In systems and methods for production of hydrocarbons fluids from a formation surrounding a wellbore, a production assembly is cemented into place, and excess cement is then cleaned from the production tubing and liner. Thereafter, hydrocarbon fluids are produced and artificial gas lift assistance is provided. All of this may be accomplished in a single trip (mono-trip) of the production tubing.

Abstract: Adjusting the confidence level of prefetch circuitry in generating outstanding prefetch address of a detected strided stream. In one example, the number of outstanding prefetches allowed is adjusted based on a determination of whether a prefetch to a prefetch address is used in a data processing system. With some systems, the higher the confidence level, the more outstanding prefetches are allowed.

Abstract: Prefetching across a page boundary in a data processing system. The system determines whether a prefetch will cross a page boundary of memory, and if so, it determines whether a translation source has an entry corresponding to the virtual address of the prefetch. If the translation source has an entry corresponding the virtual address, a physical address of the virtual address is used to prefetch the information.

Abstract: Generating a hashed value of the program counter in a data processing system. The hashed value can be used for prefetching in the data processing system. In some examples, the hashed value is used to identify whether a load instruction associated with the hashed value has an address that is part of a strided stream in an address stream. In some examples, the hashed value is a subset of bits of the bits of the program counter. In other examples, the hashed value may be derived in other ways from the program counter.
