Abstract: Apparatuses, devices, and methods for operating a voltage converter are described. A semiconductor device can include a switching circuit and a controller. The switching circuit can include a plurality of switching elements. The controller can determine an operation mode of the switching circuit. In response to the operation mode indicating a two-level operation mode, the controller can program the switching circuit to operate as a two-level voltage converter. In response to the operation mode indicating a three-level operation mode, the controller can program the switching circuit to operate as a three-level converter.

Abstract: Techniques are described for generating user customized simulation instances for testing and evaluation of software applications and services. In some cases, the system may generate user specific simulation instances to replicate in the simulation a user experience of each user when the user is engaged with the live version of the software application or service.

Abstract: A platform configured to provide a simulated content consuming environment or application accessible to one or more test users in order to determine one or more metrics associated with the user interface and/or overall experience of the streaming service and/or content that may be provided by the streaming service.

Abstract: An induced flow reciprocating double disc pump assembly includes a rotating frame supporting a double disc pump, the rotating frame has a plurality of supports and a shaft defining a horizontal axis of rotation. A stationary frame supports the rotating frame and includes a plurality of bars and uprights and a flange bearing assembly engaged each of the shafts permitting rotation between the rotating frame and the stationary frame. A locking pin positions the rotating frame and the stationary frame at a plurality of positions relative to each other. A rotation crank is engaged to the shaft. The rotating frame has a first position relative to the stationary frame supporting the double disc pump in a vertical direction and a second position where the double disc pump is in a horizontal direction.

Abstract: Disclosed herein are methods for identifying antigenic variants from cryptic lineages arising in a virus population and methods of using the identified antigenic variants.

Abstract: A platform configured to provide virtual glass in order to augment and improve focus group sessions for each actor within the ecosystem. The platform may be configured to allow a moderator, one or more test subjects, and one or more client users to participate in a focus group session at geographically diverse locations. The platform may also be configured to supplement the focus group experience by allowing for dialog and communication between the client users. In some cases, the platform may also be configured to generate and provide real time status indicators associate with the tests subject, real time text-based transcripts of the sessions, and recommendations as to the focus group direction to the moderator.
