Abstract: Described embodiments provide systems and methods for resolving Domain Name Service (DNS) requests. An authoritative DNS server may receive, from a recursive resolver, a DNS request to resolve a query on behalf of a client. The authoritative DNS server may determine whether the recursive resolver is classified as a non-client representative resolver or a client representative resolver. The authoritative DNS server may identify a redirect server based on the recursive resolver classified as the non-client representative resolver or the resolved server based on the recursive resolver classified as the client representative resolver. The authoritative DNS server may transmit, to the recursive resolver, a response to the DNS request including an address of one of the redirect server or the resolved server.

Abstract: According to one example, a tibial replacement assembly for a knee arthroplasty can be configured to couple to a resected proximal surface of a tibia of a human knee. The tibial replacement assembly can include a tibial tray and a first spike. The tibial tray can include a proximal surface and a distal surface opposing the proximal surface. The distal surface can be configured to be disposed on a resected proximal surface of a tibia. The first spike can be removably secured to the tibial tray and can extend generally distally away from the distal surface. The first spike can be configured to extend beneath the resected proximal surface of the tibia.

Abstract: The disclosure is directed at a method and apparatus for configuring and powering light fixture loads for a LED low voltage distribution system. The method and apparatus include converting power being supplied for powering the set of light fixture loads and then limiting this converted power to a set of multiple current outputs supplied to the light fixture loads. The multiple current outputs are then split or regrouped prior to being delivered to the light fixture loads.

Abstract: Techniques and systems are described for enabling local independent failure domains in a host server or datacenter environment. Included is a locally-attached independent failure device (LA-IFD) with an independent data buffer and a local communications bus for attaching to a host server. Techniques for a communications protocol between the LA-IFD and its host server are provided, including: receiving a request to write a data segment to persistent storage; synchronously storing the data segment in a buffered data segment at the LA-IFD and initiating an asynchronous update of the data segment at a remote storage system; sending a write acknowledgement indicating completion to the requestor; and, after receiving a completion notification from the remote storage system, removing the buffered data segment from the LA-IFD. In some cases, techniques allow a host server and LA-IFD pair to monitor one another for failures and implement a modified protocol in the event of unavailability.

Abstract: A bootstrap assist circuit and a startup circuit comprising a voltage controlled switch and a startup ramp voltage generator connected to the voltage controlled switch that will control a high side switch, a dimming interface or an enable/disable input function. Said system is used to provide a bootstrap technique to continuously switch a floating high side switch (MOSFET) by continuously charging a capacitor and then “level shifting” said capacitor voltage across the gate and source of the said high side switch to turn the switch on.
