Abstract: Some embodiments described herein cover a machine learning architecture with a separated perception subsystem and application subsystem. These subsystems can be co-trained. In one example embodiment, a data item is received and information from the data item is processed by a first node to generate a sparse feature vector. A second node processes the sparse feature vector to determine an output. A relevancy rating associated with the output is determined. A determination is made as to whether to update the first node based on update criteria associated with the first node, wherein the update criteria comprise a relevancy criterion and a novelty criterion. The second node is updated based on the relevancy rating.

Abstract: A system for measuring a polarization extinction ratio (PER) using a reference master test jumper (MTJ) is disclosed. The system may include an optical source to transmit an optical signal via an optical fiber. The system may also include a device under test (DUT) communicatively coupled to the optical source via the optical fiber to receive the optical signal from the optical source. The system may also include an optical measurement component communicatively coupled to the device under test (DUT). In some examples, the optical fiber may be configured or initialized to be a reference master test jumper (MTJ) that minimizes inherent polarization extinction ratio (PER) of the optical fiber when measuring a polarization extinction ratio (PER) during a measurement action.

Abstract: Techniques for interacting with a three-dimensional (3D) virtual environment including receiving a first user input for selecting a first virtual object; identifying, in response to the first user input, the first virtual object as a currently selected virtual object; receiving a second user input for activating an object reorientation mode; activating, in response to the second user input, an object reorientation mode; receiving a third user input indicating changes in pose of a hand; receiving, while the first virtual object has remained a currently selected virtual object the object reorientation mode has remained active, a fourth user input; identifying a first orientation of a reference virtual object; and changing, in response to receiving the fourth user input, an object space orientation of the first virtual object to having the first orientation from a different second orientation.

Abstract: Methods and systems are provided for an alert system for reducing a risk of an adverse health event in a firefighter or first responder. In one example, the alert system may comprise a wearable sensor and an alerting device, where the alerting device may be operable to receive physiological and/or environmental data from the wearable sensor and where the alerting device may be further operable to issue an alert based on the received physiological and/or environmental data. In some examples, the alert may be a function of one or more personalized thresholds for evaluating a stress level of the firefighter or first responder. In some examples, the alert may be issued via multiple communication channels.
