  • Patent number: 11968200
    Abstract: An enterprise platform may retrieve, from a collaboration data store, information about a selected enterprise team. The enterprise platform may then transmit, from a set of integration tools to a workflow tool of a remote cloud-based environment, a data payload including a notification request associated with a channel. The enterprise platform may also transmit, from a runtime environment to a business communication platform of the cloud-based environment, a request to post a notification to the channel and arrange for a member of the selected enterprise team to receive an adaptive information card, pushed by the business communication platform via the channel, containing information associated with at least one of the integration tools. The member who receives the adaptive information card may also, via selection of a graphical icon on the card, respond to the business communication platform via bi-directional communication.

  • Patent number: 7622051
    Abstract: A method of etching a substrate in a plasma processing chamber is disclosed. The method includes introducing the substrate having thereon an underlying layer, an anti-reflective layer above the underlying layer, and a photo-resist layer above the anti-reflective layer into the chamber. The method also includes flowing a gas mixture into the chamber, the gas mixture includes a flow of a hydrofluorocarbon gas, a flow of fluorocarbon gas, a flow of a halogen-containing gas other than the hydrofluorocarbon gas, and a flow of oxygen gas. The method further includes striking a plasma from the gas mixture. The method additionally includes etching at least through the anti-reflective layer with the plasma.

  • Patent number: 7477756
    Abstract: An insert earphone comprises a housing and at least one transducer that is located in the housing. The transducer is adapted to receive electrical energy and to responsively convert the electrical energy into acoustic energy for presentation to an eardrum of a user. The transducer is positioned within the housing so as to be in close proximity to the eardrum of the user when the housing is inserted into the ear canal. At least one sealing member is coupled to the housing. The at least one sealing member is adapted to provide an acoustic seal within the ear canal of the user.
