Abstract: A method includes: via a user interface of a hub device, receiving a first set of user credentials associated with a first operator, the hub device connected to a set of mobile devices; accessing a first operator schedule defining a first manufacturing operation and a first observer of the first manufacturing operation, the first observer characterized by a first set of observer credentials; detecting disconnection of a first mobile device in the set of mobile devices from the hub device, the first mobile device associated with a first device ID; in response to detecting disconnection of the first mobile device from the hub device, associating the first device ID with the first operator; and serving a first video feed from the first mobile device to the first observer based on the first device ID and the first set of observer credentials.

Abstract: A cathode structure for use in an OLED device having one or more OLED layers includes a thin light-transmissive layer having a top surface and a bottom surface and including silver (Ag) wherein the Ag acts as a conductor for the cathode structure, and a light-transmissive electron-injecting layer disposed in contact with the bottom surface of the thin light-transmissive layer and with an underlying OLED layer. The structure also includes an oxide layer disposed over the thin light-transmissive layer, and a separation layer disposed between the top surface of the thin light-transmissive layer and the oxide layer.
