Abstract: A transistor structure that includes multiple heterojunction layer sets, each generating a two-dimensional electron gas (2DEG), such that the transistor structure has a stack of 2DEGs that may be used to conduct between source and drain. A terminal is provided proximate an uppermost 2DEG to control whether the uppermost 2DEG is continuous between a source contact and a source plug. A source plug connects the uppermost 2DEG with the next 2DEG, and a drain plug also connects the uppermost 2DEG with the next 2DEG. Thus, the gate terminal may control the flow of current in sub-surface 2DEGs between the source and drain.

Abstract: A speech processing system includes an input for receiving an input utterance spoken by a user and a word alignment unit configured to align different sequences of acoustic speech models with the input utterance spoken by the user. Each different sequence of acoustic speech models corresponds to a different possible utterance that a user might make. The system identifies any parts of a read prompt text that the user skipped; any parts of the read prompt text that the user repeated; and any speech sounds that the user inserted between words of the read prompt text. The information from the word alignment unit can be used to assess the proficiency and/or fluency of the user's speech.

Abstract: Wafer testing of a power transistor for a current property of the power transistor. Wafer testing of a power transistor is performed by using a sense transistor constructed using the same epitaxial stack as was used to construct the power transistor. The current property of the sense transistor is then measured, and the current property of the power transistor can be determined from that measurement. Furthermore, the sense transistor is pre-conditioned prior to the measurement by alternately turning on and off the sense transistor multiple cycles while allowing a source terminal of the power transistor to float. This simulates operating conditions of the power transistor, thereby allowing for measurement of the current property of the power transistor as it would likely be in operation.

Abstract: The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. One or more computing devices can install malware code into a network device after exploiting a vulnerability of the network device.

The monitoring and mitigation service can identify the internet protocol (IP) address or any routing information regarding the computing devices that sent the malware code. Based on the identified information, the monitoring and mitigation service can identify and implement the network mitigation information in the form of null routing addresses that will cause network communications associated with the identified computing device to be terminated or otherwise not delivered to the intended network-based resources.

Abstract: A continuous variable planetary (CVP) system includes a CVP hub, which includes a shift mechanism including a shift driver element, and a processing server system to calibrate the CVP system and detect errors within the CVP system. The processing server system performs continuously monitoring or obtaining a transmission speed ratio of the CVP hub. Upon detecting that the transmission speed ratio reaches a particular value, the processing server system records a corresponding position of the shift driver. The processing server system calibrates the CVP system based on the particular value, the corresponding position, and a known relationship between transmission speed ratios and positions of the shift mechanism. The processing server system determines or verifies a full underdrive (FUD) position by iteratively reducing a transmission speed ratio from the particular value until an onset of a backlash condition is detected and determines or verifies a full overdrive (FOD) position.
