Abstract: A connector for use in a respiratory system. The connector can connect a first respiratory system component such as a filter to a second respiratory system component. The connector has a body defining a bore for receipt of a complementary connector component. The bore has a terminal end that provides an entry into the bore for the complementary connector component. The connector comprises at least one internal retaining feature, at least one internal alignment feature, and/or at least one external alignment feature.

Abstract: A non-penetrating captive bolt device includes a threaded mechanism for retracting a bolt against a biasing force. The bolt includes an elongated rod that projects rearward from the rear end of the bolt through a compression type spring that biases the bolt forward. A trigger actuated catch is mounted on the threaded mechanism with an internal bore, and the rod extends therein. When the threaded mechanism is advanced forward, the trigger actuated catch is advanced forward and engages the elongated rod. Retracting the threaded mechanism retracts the elongated rod and compresses the spring. Actuating triggers on the trigger actuated catch releases the elongated rod and the spring biases the bolt to a forward position.

Abstract: Systems, methods, and apparatus are disclosed that provide in-service traffic and/or resource migration between processing units in a communications network. An example method includes one or more processing units communicating with at least one processing unit of a plurality of processing units, where the communicating corresponds to a plurality of resources and resource requirements of the plurality of processing units. The one or more processing units evaluate resource utilization and projected traffic of a subset of the plurality of processing units. The one or more processing units determine, based on the resource requirements, to migrate one or more selected interdependent resources for a service from one or more processing units to one or more receiving processing units of the plurality of processing units.

Abstract: An audio mixer for mixing audio signals from a plurality of participants, including audio signals of different sample rates; the audio mixer comprising: a plurality of mixing arrangements, each mixing arrangement for a given one of said sample rates; each mixing arrangement comprising: a pre-mixer configured to mix audio signals having the given sample rate; one or more resamplers, each resampler configured to convert pre-mixed audio signals from other mixing arrangements into a signal of the given sample rate; and a post-mixer configured to mix the output of the pre-mixer with the output of each resampler to produce an output at the given sample rate; the audio mixer further comprising a subtractor configured to subtract the participant's input audio signal from the post-mixed output.

Abstract: In one embodiment of the invention, an integrated device is described that employs a mechanism to control power consumption of a graphics memory controller hub (GMCH) through both voltage and frequency adjustment of clock signal received from a clock generator. The GMCH comprises a graphics core and a circuit to alter operational behavior, such as the frequency of a render clock signal supplied to the graphics core. The circuit is adapted to monitor idleness of the graphics core and reduce a frequency level of the render clock signal if the idleness exceeds a determined percentage of time.

Abstract: Methods and devices for power management of graphics or other computer subsystems are disclosed. In one embodiment, graphics software components are configurable in a manner that allows them to place the graphics subsystem is a “safe” state prior to a suspend event, and back into a “working” state after a resume event, without explicit support from an operating system (OS) power management driver. When operating in the absence of an OS-supplied driver, the graphics driver receives notification of power management events, and sends a message to a support application, which then causes the graphics to enter a quiescent state by taking exclusive ownership of the display and issuing standard device-independent OS graphics calls (for a power-down event) or to relinquish display ownership (for a power-up event). From within this quiescent state the graphics may be safely power managed without adverse effects to the graphics chips and without creating any instabilities in other graphics applications.

Abstract: A down-hole well tool is disclosed for removing debris from a well utilizing low pressure/suction. More particularly, the tool is adapted to generate the low pressure within a well bore for removing debris while being interconnectable to the end of a single duct tubing that extends to the surface. Use of the low pressure/suction allows removal of debris without of forcing such debris into the permeable formations of the well. In one application, the tool may be utilized during open-hole completion processes. In another application, the tool may be utilized to clean existing wells.

Abstract: A compact hybrid comprises reactive power-dividers and signal paths coupling the reactive power-dividers to provide a predetermined phase difference therebetween. The signal paths may have 90-degree bends therein to reduce a distance between adjacent reactive power-dividers to less than a physical distance associated with the predetermined phase difference in a stripline medium. The hybrid may be a 180-degree hybrid and may be part of RF circuitry of a wireless communication device to combine signals from a pair of antennas and to provide a sum signal and a difference signal. The RF circuitry may also comprise switching circuitry to select between the sum signal and the difference signal based on a signal quality of the sum and difference signals.
