Methods and apparatus for compressing and decompressing a higher order ambisonics representation
Higher Order Ambisonics represents three-dimensional sound independent of a specific loudspeaker set-up. However, transmission of an HOA representation results in a very high bit rate. Therefore, compression with a fixed number of channels is used, in which directional and ambient signal components are processed differently. The ambient HOA component is represented by a minimum number of HOA coefficient sequences. The remaining channels contain either directional signals or additional coefficient sequences of the ambient HOA component, depending on what will result in optimum perceptual quality. This processing can change on a frame-by-frame basis. |

Acoustic chambers to improve sound reproduction between left and right earcups
This application is directed to acoustic chambers that can be incorporated into headsets to improve consistency of sound reproduction between a left and right earcup. Headsets, especially wireless headsets, need to hold many different components within the earcups (e.g., batteries, wireless components, etc.). As earcups are required to hold more components, imbalances between left and right can result. For example, a left earcup might hold a battery, while a right earcup holds wireless charging components. Differences between left and right components can ultimately result in sound reproduction inconsistencies between left and right earcups. Embodiments of the inventive subject matter create consistent acoustic chambers for both left and right earcups so that sound reproduction between the earcups is unaffected by components housed within each earcup. |

Client controlled domain name service (DNS) resolution
In one embodiment, a domain name system (DNS) server processes a DNS query based on a policy statement that is attached to the DNS query. Upon receiving the DNS query, the DNS server executes one or more commands specified in the policy statement to generate a query state. The query state controls DNS resolution behavior that the DNS server implements as part of processing the DNS query. The DNS server then performs one or more DNS resolution operations based on DNS query and the query state to generate a response. Advantageously, because the semantics of the policy statement are encapsulated within the policy statement, the policy statement enables a client to unambiguously control DNS resolution behavior. By contrast, conventional DNS resolution guidance mechanisms that rely on DNS servers to infer policies based on client data may not reflect the preferences of the clients. |

Health checking in a distributed load balancer
A distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer nodes.

Rather than advertising itself, however, a load balancer node may be advertised to the router by one or more neighbor load balancer nodes; the neighbor nodes may terminate the BGP sessions with the router in response to determining that the load balancer node has failed. |

Non-orthogonal multiple access for uplink data transmission for 5G or other next generation network
The gains with non-orthogonal multiple access (NOMA) for uplink data transmissions can be high when chosen codes are orthogonal. However, when codes are non-orthogonal, the gains can be low. NOMA can be used when there is more than one mobile device using the same resources. Since orthogonal codes cannot be possible for every length, codes which have low cross-correlation properties can be used. However, when there are a large number of mobile devices using the same resources, the cross-correlation between the codes can cause interference to the mobile devices. Reducing the gains of a NOMA system can reduce the overall throughput. Thus, transmitting data on the same resources in a NOMA can occur in spite of the interference to the UEs transmitting data on the same resources. Therefore, a non-orthogonal multiple access design for a 5G network can mitigate interference. |
