Abstract: Acoustic echo cancellation systems and methods are provided that improve the quality of the audio transmitted from by an audio device a near end to a far end when a doubletalk condition is present, including allowing certain subbands of an echo-cancelled signal to be less attenuated by overriding certain gains of subbands of the echo-cancelled audio signal in a non-linear processor, and compressing and applying makeup gain to a remote audio signal.

Abstract: This invention relates to a computer-implemented simulation system comprising a needle device having a retractable needle shaft comprising a resistance mechanism which can be activated to vary the resistance of the needle shaft. A processing module is configured to: receive ultrasound image data representative of a subject being scanned, receive position and orientation data representative of an ultrasound probe and a needle device, calculate a projected path for the needle device and generate a simulation needle from the projected path. When the simulation needle is determined to intersect with an identified tissue type, it modulates a signal and sends the modulated signal to the resistance mechanism, thereby to cause a change in the resistive force acting on the retractable needle shaft. The invention also relates to a computer-implemented method for simulating ultrasound guided needling using this system.

Abstract: A scan window for an imaging system includes at least one flexible sheet made of an X-ray transparent material and having a first end and a second end. The scan window also includes at least one tapered joint formed between the first end and the second end and secured via a bonding agent to form a joined member with the at least one flexible sheet.

Abstract: Apparatus and methods for mitigating network attacks, such as by dynamically re-routing traffic. Various disclosed embodiments manipulate path-based routing of the backbone network to insert a scrubbing appliance within the backbone network topology, rather than using traditional network addressed tunnels in the edge network. In one implementation, traffic entering the backbone network ingress peer routers (from either another backbone network, or an edge network) is normally destination-address routed via the backbone to its appropriate egress router based on a path label; however, when a Distributed Denial of Service (DDoS) attack is detected, the ingress peer router inserts an additional hop into the path label that redirects dirty traffic to a substantially centralized scrubbing appliance. The benefits of the disclosed solutions include, among other things, significantly reduced attack response/recovery times without significant capital outlays.

Abstract: Methods and apparatus for resolving resource contention in a content distribution network. In one embodiment, a manager entity at a subscriber premises manages requests for content from various subscriber devices in communication therewith. The manager identifies when there is a conflict, and implements a mechanism to resolve the conflict, such as by determining whether one or more conflicting content items may be provided according to an alternate delivery scheme. In one variant, the apparatus may further implement one or more rules for determining whether to adjust delivery of requested content. In another variant, the disclosed concepts may be utilized to provide efficient delivery of content, by providing alternate delivery prior when doing so would be more efficient than allowing for delivery at a first scheduled date/time. The system may take into account bandwidth or network constraints, whether other requests are pending (although there are still sufficient resources), etc.

Abstract: A component from a substrate processing chamber which has plasma process residues on both its internal and external surfaces, is removed from the processing chamber, and transferred to a cleaning chamber. The component is exposed to an energized cleaning gas in the cleaning chamber, and the cleaning gas is exhausted from below the component so that the cleaning gas cleans off the residues on both the internal and external surfaces of the component. It has been determined that the cleaning gas can also repair surface defects in the component.
