  • Publication number: 20230128641
    Abstract: Disclosed are example purge valve assemblies for a printing system and related methods. In an example, the purge valve assembly includes a valve body to couple to a carriage of the printing system. In addition, the purge valve assembly includes an actuator, an arm, and a diaphragm coupled to the arm and the valve body. The purge valve assembly is to transition between: a first position in which the actuator is disposed at an initial position and the diaphragm is extended outward from the valve body; and second position in which the actuator is translated along an axis from the initial position to slidingly engage with the arm to rotate the arm and depress the diaphragm toward the valve body.

  • Patent number: 11012437
    Abstract: Embodiments disclosed provide access to Traversal Using Relays around Network Address Translation (TURN) servers using trusted single-use credentials, and related methods, systems, and computer-readable media. In one embodiment, a method comprises receiving, by a TURN authentication agent, a request for a TURN server credential. Responsive to determining that the request is authorized, the agent generates a trusted single-use credential and transmits it to the requestor. Using this trusted single-use credential allows untrusted clients to access a TURN server without exposing a userid/password combination. In another embodiment, a method comprises receiving, by the TURN server, a request for a TURN service. The server challenges the request, and receives a userid and a password. Responsive to determining that the userid and the password constitute a trusted single-use credential and responsive to determining that the request is authorized, the server provides the TURN service for the requestor.

  • Patent number: 10893008
    Abstract: A method for generating and communicating communication components over a messaging channel is provided. The method includes (i) presenting a structured micro block based on a conversation in a form of unstructured natural language in the messaging channel between a user and an agent (ii) incorporating the structured micro block that collects strongly typed information from the user as a part of the conversation in the messaging channel, (iv) generating a structured workflow by interleaving the structured micro block with the unstructured natural language, and (v) communicating the structured workflow over the messaging channel for enabling the user to perform one or more operations.

  • Patent number: 10263952
    Abstract: Providing origin insight via Session Traversal Utilities for Network Address Translation (STUN) messages for web applications, and related methods, systems, and computer-readable media are disclosed herein. In one embodiment, a method for providing origin insight for web applications via STUN messages comprises determining an origin identifier for a web application attempting to send a STUN message to a STUN server; generating the STUN message incorporating the origin identifier for the web application; and transmitting the STUN message to the STUN server. In another embodiment, a method for providing STUN services to web applications comprises receiving a STUN message from a web client, and extracting an origin identifier for a web application. Provision of a STUN service to the web application is determined based on the origin identifier. If the STUN service should not be provided, the STUN message is rejected or disregarded; otherwise the STUN message is processed.

  • Publication number: 20180240162
    Abstract: Communications often require the prior selection of a particular mode of communications. A voice call requires initiation of a telephone connection (e.g., dialing a number) in a telephone application or interface, an email communication requires selection of an email address in an email application or the launching of such an email application. Omni-channel communications, as described herein, enable a connection to be initiated in a unified platform for any available mode of communication. Communications may incorporate workflow management and widgets to dynamically present or receive information from a user or access other device hardware (e.g., camera, GPS receiver, etc.) or data (e.g., images, videos, documents, etc.).
