Abstract:

An acoustic-drum tuning assembly includes a single adjustment feature to vary the drumhead tension uniformly around the drumhead's periphery. The tuning mechanism includes multiple rings located between the end of the drum shell (or support ring) and the “underside” of the drumhead, which is otherwise restrained with respect to the drum shell by a hoop or rim fixed in place by threaded tension rods and lugs or other hoop-fixing mechanism. The single adjustment feature varies the circumference of a wedging ring, which generates an axial force “expanding” or “retracting” the tuning assembly along the central axis of the drum. When the tuning assembly axially “expands”, it pushes increasingly “upward” against the drumhead, variably increasing its tension and the musical pitch of the drum. When the tuning assembly axially “retracts”, it decreases the “upward” push, variably decreasing the drumhead tension and lowering the musical pitch of the drum.

Abstract:

Technologies are disclosed for monitoring network traffic using traffic mirroring. According to some examples, traffic mirroring allows customers to monitor traffic at different sources within a VPC. For example, a source may be any Elastic Network Interface (ENI) in their VPC, including elastic network interfaces (ENIs) on virtual machine instances, Network Address Translation (NAT) Gateways, Load Balancers, VPC endpoints, Internal Gateways, Transit Gateways, and more. Filters can be utilized to determine the network traffic to mirror. A customer may also configure to monitor real-time traffic with a monitoring appliance of their choice. With traffic mirroring, data traffic may be identified and sent to one or more target devices. Customers may monitor traffic within a VPC for content inspection, forensic analysis, troubleshooting, record keeping, and the like. Using traffic mirroring, customers can replicate VPC traffic, along with full payload data, without installing and managing agents on virtual machine instances.
