Abstract: A gesture-based wake process for an AR system is described herein. The AR system places a hand-tracking input pipeline of the AR system in a suspended mode. A camera component of the hand-tracking input pipeline detects a possible visual wake command being made by a user of the AR system. On the basis of detecting the possible visual wake command, the AR system wakes the hand-tracking input pipeline and places the camera component in a fully operational mode. If the AR system, using the hand-tracking input pipeline, verifies the possible visual wake command as an actual wake command, the AR system initiates execution of an AR application.

Abstract: Embodiments of the invention are directed to an automated account restoration system. In some embodiments, the system determines a state of an account based on a likelihood that the account has been compromised. If the account is determined to be in a low-risk state, then upon an successful login to that account, a verification cookie may be generated which is unique to a user device used to access the account. If the account is determined to be in a high-risk state, then system may prevent access to the account except by user devices that include a valid verification cookie.

Abstract: A two-piece seal assembly includes first and second seal subassemblies, each shaped as a semicircular ring. The first seal subassembly has a first stator subassembly and a first rotor subassembly that cooperate to form a first semicircular segment of a labyrinth. The second seal subassembly has a second stator subassembly and a second rotor subassembly that cooperate to form a second semicircular segment of the labyrinth. The first and second stator subassemblies, when affixed to each other, form a ring-shaped stator that encircles a rotation axis. The first and second rotor subassemblies, when affixed to each other, form a ring-shaped rotor that encircles the rotation axis and can rotate about the rotation axis relative to the stator. When the first and second seal subassemblies are affixed to each other, the first and second semicircular segments meet such that the labyrinth encircles the rotation axis.

Abstract: A method of operating a vehicle, such as an autonomous vehicle, includes the steps of receiving a message from roadside infrastructure via an electronic receiver and providing, by a computer system in communication with said electronic receiver, instructions based on the message to automatically implement countermeasure behavior by a vehicle system. Additionally or alternatively, the method may include the steps of receiving a message from another vehicle via an electronic receiver and providing, by a computer system in communication with said electronic receiver, instructions based on the message to automatically implement countermeasure behavior by a vehicle system.

Abstract: A device for detecting stray electrical currents in fluid mediums comprises at least two probes for partially disposing in a fluid medium and a control unit. The control unit comprises at least one analog-to-digital signal converter in electrical communication with at least one of the probes, at least one audio-visual alarm, and a processor operably coupled to the at least one converter and to the at least one audio-visual alarm. The processor is operable to measure an electrical potential difference between the two probes, to calculate at least one frequency-dependent characteristic associated with a plurality of said measurements, and to transmit an alert signal if the at least one frequency-dependent characteristic satisfied a threshold. Advantageously, by monitoring for the frequency, the device more consistently and more reliably detects the presence of stray alternating currents.

The strap assembly includes an elongated strap extending from the body; a fastener protrusion extending from a surface of the elongated strap; and a faster housing extending from an outer surface of the back side of the body.

Abstract: A method and system for remediating vulnerable code libraries, including open source libraries, in a software application. An application, that uses code libraries, and information regarding known library vulnerabilities are received, then it is determined if one or more libraries in the application are vulnerable based upon the information. For each of the one or more vulnerable libraries, a library version that minimizes risk is determined. The determined library version is incorporated into the application to form a test application, and an application test is performed on the test application. If an application test score on the test application is below a predetermined threshold, the determined library version is incorporated into a final application precursor. A final application can be determined from the final application precursor for each of the one or more vulnerable libraries.

Abstract: A modular seating assembly includes a top backrest portion, a seat support structure, and a bottom seating portion. The top backrest portion includes a backrest frame, a first backrest cushion, a backrest gap, and a second backrest cushion. The seat support structure includes a pair of supports connecting the top backrest portion and the bottom seating portion to one another to form the modular seating assembly. The bottom seating portion includes a seat apex section including the second backrest cushion, and a seat base section on which the seat apex section is disposed when the bottom seating portion is in a closed position.
