Hearing device comprising a GSC beamformer
The application relates to a hearing device comprising a beamformer of the generalized sidelobe canceler (GSC) type. The application further relates to a method of operating a hearing device. The disclosure addresses a problem which occurs when using a GSC structure in a hearing device application. The problem arises due to a non-ideal target-cancelling beamformer. As a consequence, a target signal impinging from the look direction can—unintentionally—be attenuated by as much as 30 dB. To resolve this problem, it is proposed to monitor the difference between the output signals from the all-pass beamformer and the target-cancelling beamformer to control a time-varying regularization parameter in the GSC update. This has the advantage of providing a computationally simple solution to the non-ideality of the GSC beamformer. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems, or combinations thereof.

Systems and methods for caching HTTP post requests and responses
With an idempotent POST request, the URL (and headers) cannot be used as an HTTP cache key. To cache idempotent POST requests, the POST body is digested and appended the URL with the digest and used as the cache key. Subsequent requests with the same payload will end up hitting the cache rather than the origin server. A forward cache proxy at the client end and reverse cache proxy at the server end are deployed. The client sends the request to the forward proxy that looks up the cache. If there is a cache miss, the forward cache proxy digests the body and sends only the digest to the reverse proxy. The reverse cache proxy looks up request cache to find if there is a match for the request and send that request to the server.

Method and system for managing user state for applications deployed on platform as a service (PaaS) clouds
The REsilient LOosely Coupled (ReLoC) system and method implement a session-state management architecture for cloud computing that uses loosely-coupled services and platform agnostic scalable messaging technology to propagate and save session states. Maintaining the state of applications and user sessions is difficult in large scale web-based software systems, particularly in the context of cloud computing (e.g., platform as a service (PaaS) vendors, do not explicitly support state management infrastructure, such as clustering). In a PaaS environment, a user has little or no access and control over the server platform and session management layer. The platform tiers are generally loosely coupled and service-oriented, which make traditional session-state management techniques non-usable. The ReLoC system and method provides a high level of tolerance to failures of the platform tiers without corresponding disruptions in user sessions. In the context of PaaS Clouds, the ReLoC system provides greater scalability compared to traditional clustering environments.

Low latency live video streaming
Techniques are disclosed for low latency live video streaming. A client can be configured to send a single HTTP request for live video streaming to a server. The server can be configured to push one or more video segments to the client in response to the request, following a pre-defined push strategy. For example, using a so-called all-push strategy, the client sends only one request to the server, and in response, the server sends all of the video segments to the client as soon as each segment is complete. The HTTP 2.0 protocol may be used for pushing the video from the server to the client. This technique eliminates the request explosion problem when small segments are used. Further, the number of segments pushed with each request can be varied, which is to facilitate adaptive bitrate switching.
