Abstract: Internet-of-Things (IoT) devices can be used to perform authentication related operations because IoT devices are prevalent in our society and because a server performing an authentication operation can communicate with IoT devices via the Internet. In a first example authentication technique, a server determines whether a person can perform an operation requested by the person based on whether the person performed an action on an IoT device, where the action is selected by the server and send to the person's user device. In a second example authentication technique, a server determines whether a person can perform an operation based on whether a person accurately identified an action performed by an IoT device, where the IoT device performs the action based on a command sent by the server.

Abstract: A system may include a first vehicle and a first control system that may control one or more vehicle operations of the first vehicle. The first control system may perform operations including receiving a first vehicle operation signal from a second control system associated with a second vehicle, sending one or more requests to one or more computing systems for a confirmation of the first vehicle operation signal, and determining a set of vehicle instructions to control the one or more vehicle operations based on whether one or more responses from the one or more computing systems provide the confirmation. The first control system may then control the first vehicle based on the set of vehicle instructions.

Abstract: A polarization scrambler using a retardance element (RE) is disclosed. The polarization scrambler may include an optical fiber input to transmit an optical signal, and a beam expander to receive and expand the optical signal to create an expanded optical signal. The polarization scrambler may include a retardance element (RE) to cause a polarization scrambling effect on the expanded optical signal and to create a scrambled expanded optical signal. The polarization scrambler may include a beam reducer to receive and reduce the scrambled expanded optical signal to create a scrambled optical signal. The polarization to scrambler may include an optical fiber output to receive scrambled optical signal. The optical fiber output may transmit the scrambled optical signal to one or more downstream optical components.

Abstract: The present disclosure relates to preventing laser access to microphones of smart devices. In one embodiment, a microphone of the smart device may be covered with an opaque material such as a cloth cover. The opaque material may serve as a barrier that is impenetrable to light, thereby preventing laser light to reach the microphone. In a further embodiment, a smart device may prevent the one or more microphones of the smart device from receiving an audio command embedded in a light signal by disrupting the light signal, ignoring the audio command, or both. In another embodiment, the smart device may block the audio command from being received at a microphone of a smart device by determining a frequency of the light signal, instructing a laser jammer to transmit a counter light with the frequency to interfere with the light signal.

Abstract: The method for dirty camera detection including: detecting a first predetermined state change event; sampling a set of cavity measurements; optionally determining a set of features of the set of cavity measurements; determining a class label based on the cavity measurements; optionally verifying the classification; and facilitating use of the appliance based on the classification.

Abstract: Authentication techniques are described to allow a person to be authenticated to interact with an organization, where a type of authentication can be determined based on an environment in which the person is located. For example, an authentication server can collect a status information related to a safety setting of a mobile device. The safety setting can be enabled, e.g., if a person is driving a vehicle. When enabled, the safety setting can prevent the person from performing one or more operations on the mobile device. Based on the collected status information, the authentication server can request the person to provide user information via the mobile device so that the authentication server can determine whether the person is authenticated to interact with an organization.

Abstract: In various implementations, a device surveys a scene and presents, within the scene, a extended reality (XR) environment including one or more assets that evolve over time (e.g., change location or age). Modeling such an XR environment at various timescales can be computationally intensive, particularly when modeling the XR environment over larger timescales. Accordingly, in various implementations, different models are used to determine the environment state of the XR environment when presenting the XR environment at different timescales.

Abstract: A method and system of providing guidance and information to an end-user during an emergency situation. A network of one or more enrolled devices can obtain infrared data that will be used by the system to determine whether there is a high likelihood of a fire in a building. When an emergency situation such as a fire is detected, alerts can be generated at the enrolled devices that provide navigation cues based on user preferences and suggested evacuation routes to safely guide the end-user to the nearest designated exit.

Abstract: A system and method for improving the download time of emails in an environment in which a server distributes emails to persons working in close proximity to each other. When these persons receive multi-recipient emails intended for several or all of these persons, the server distributing the emails delivers the multi-recipient emails to the first one of the persons who logged on to read his or her emails on his or her personal computer, for distribution to the other persons over a personal area network. This reduces the download time for the persons downloading their emails at a subsequent time.

Abstract: The disclosed wearable device systems include several features for alerting and guiding persons who are approaching or near to potentially hazardous or high-risk conditions in their nearby environment. Sensor data from wearable devices (also referred to herein as “wearables”) are used to determine the presence of various unsafe environmental conditions and phenomenon, including dangerous terrain or other unusual conditions. The wearable would be used to warn a person, for example via auditory or haptic-based feedback, if the person is about to encounter an unsafe condition. In particular, the proposed systems can be of great benefit to the visually impaired, those persons with physical disabilities, or persons otherwise vulnerable to particular environmental conditions.
