Abstract: In one embodiment, an endpoint in a network sends a Session Initiation Protocol (SIP) registration request to a device. The device generates a first key using information included in the SIP registration request. The device also writes the first key to a storage location accessible by a Traversal Using Relays around Network address translators (TURN) server. The endpoint generates a second key based on the information included in the SIP registration request. The endpoint sends an allocate request to the TURN server that includes the second key. The TURN server authenticates the endpoint based in part by comparing the second key to the first key. The endpoint receives an allocate response from the TURN server, after the TURN server authenticates the endpoint.

Abstract: In one embodiment, a request to join an electronic chat room is received from a requester. A selection of an access control level for the requester is received via a user interface in order to grant the requester access to the electronic chat room according to a condition for granting access. The user interface is used to assign a selected access control level to the requester, thereupon granting access to the requester. The requester's access to content available in the electronic chat room being limited based on the selected access control level. Related methods, apparatus, and systems are also described.

Abstract: Absorbent laminates and folded multi-layer absorbent cores including one or more of the present absorbent laminates The present absorbent laminates comprise an absorbent layer between two laminate layers, at least one of which absorbent laminates including a spunlace nonwoven. Some of the present multi-layer absorbent cores are folded to define a channel running longitudinally along the core to enhance liquid distribution and absorption.

Abstract: Various embodiments describe controlling usages of channels of a user experience ecosystem. A computer system provides a user interface to a computing device, generates data entries based on user interactions with the user interface, and stores the data entries in a data store. The data entries identify the channels and specify dependencies between the usages of the channels. The computer system adds, to the data store, identifiers of storage locations of content. The computer system provides, to channel systems, access to the data entries and the identifiers of the storage locations in the data store. A usage of a channel by a channel system includes a content publication based on the data entries and the identifiers of the storage locations. The usage of this channel is coordinated with a usage of a different channel by a different channel system based on the dependencies specified in the data entries.

Abstract: Technologies for engine fluid quality monitoring are disclosed herein. An engine system includes a sensor and an engine controller. The sensor generates sensor data indicative of a fluid property of engine fluid of a gas turbine engine of the engine system. The engine fluid may be engine oil or fuel. The fluid quality may be viscosity, water content, calorific content, specific gravity, heating value, or the presence of contaminants in the engine fluid. The engine controller determines the fluid property based on the sensor data and outputs the fluid property. The fluid property may be stored in non-volatile storage. A user alert such as a cockpit alert may be generated based on the fluid property. A control law of the gas turbine engine may be modified as a function of the fluid property. The engine controller may include the sensor.

Abstract: Technologies for engine fluid quality monitoring are disclosed herein. An engine system includes a gas turbine engine having one or more mechanical components, a fluid quality sensing system, and an engine controller. Each mechanical component includes a tracer material embedded in the mechanical component during manufacture. The fluid quality sensing system applies a laser beam to debris captured in an engine fluid of the gas turbine engine and detects a light signature generated by tracer material in the debris in response to application of the laser beam. The engine controller identifies the tracer material as a function of the light signature. The engine controller determines a potential wear state of a mechanical component as a function of the tracer material. The engine controller may select the mechanical component from multiple mechanical components based on the tracer material. Each mechanical component has a predetermined association with a corresponding tracer material.
