Abstract: A method for providing device support to a user using an augmented reality (AR) interface includes establishing, by a computer system, a real-time communication session streaming audio and video between (i) a local application executing on a local user device and (ii) a remote application executing a remote user device. The method further includes transmitting, via the real-time communication session, images depicting equipment captured by the local application. Annotations to the images are received from the remote application. Each annotation is anchored to user-selected positions on the equipment. The annotations are presented on the remote user device overlaid on the equipment at the user-selected positions. The real-time communication session is used to transmit audio or video instructional information related to the equipment and referencing the annotations. The computing system stores a new session record that includes the images, the annotations, and the audio or video instructional information.

Abstract: A system for validating workflow task completion, includes a computer in communication with a user device that provides instructions related to a workflow and obtains an indicator input associated with a state of a monitored device, the computer having a deep learning module that receives the indicator input. The system includes a reference database storing reference data associated with different states of the monitored device, and a task database storing a plurality of workflow task steps. The deep learning module identifies an object of the monitored device within the indicator input, detects a state of the object by comparing the indicator input to at least one reference datum, and validates whether a current task step is completed based on the detected state of the object. The computer obtains another task step of the workflow based on a result of the validation and adjusts the instructions provided by the user device.

Abstract: An amplifier system includes a power divider for dividing an input RF signal into M RF signals of equal power and phase. The system has M low power selectable phase shifters each for phase shifting one of the M RF signals. M high power amplifiers are coupled to respective ones of the phase shifters. The system includes an M×N power distribution network having M input ports and N output ports, such as a Butler matrix. The M high power amplifiers are connected to a respective one of the M input ports of the distribution network. The phase of the M phase shifters may be adjusted to obtain a maximum output at the desired output with all the other outputs nulled.
