Abstract: A serial data receiver subsystem included in a computer system may include a data detection circuit, a speed detection circuit, and a receiver circuit that includes multiple subcircuits. The data detection circuit performs a comparison a reference voltage to the magnitude of signals received via a communication link that encode a serial data stream consisting of multiple data symbols. Using a result of the comparison, the data detection circuit may activate a indicating the presence of data on the communication link. Once the is active, the speed detection circuit checks the number of transitions to determine a rate at which data is being transmitted. In response to a determination that the rate of the data being transmitted exceeds a threshold value, the receiver circuit activates one or more of the multiple subcircuits.

Abstract: A method of traffic forwarding and disambiguation through the use of local proxies and addresses. The technique leverages DNS to on-ramp traffic to a local proxy. The local proxy runs on the end user's device. According to a first embodiment, DNS is used to remap what would normally be a wide range of IP addresses to localhost based on 127.0.0.0/8 listening sockets, where the system can then listen for connections and data. In a second embodiment, a localhost proxy based on a TUN/TAP interface (or other packet interception method) with a user-defined CIDR range to which the local DNS server drives traffic is used. Requests on that local proxy are annotated (by adding data to the upstream connection).

Abstract: Techniques for control of power switches in a USB Power Delivery (USB-PD) system are described herein. In an example embodiment, an integrated circuit comprises a programmable gate control circuit coupled to a provider field effect transistor (FET) and a consumer FET to provide control signals to the provider and consumer FETs in response to system conditions and application requirements of the USB-PD system. A pulldown current control circuit may provide additional control to slew rate for the slow turn-ON of provider and consumer FETs.

Abstract: Embodiments include nonvolatile a memory (NVM) device that can be configured for logic switching and/or digital computing. For example, embodiments of the NVM device can be configured as any one or combination of a memory cell, a D flip flop (DFF), a Backup and Restore circuit (B&R circuit), and/or a latch for a DFF. Any of the NVM devices can have a Fe field effect transistors (FeFET) configured to exploit the IDS?VG hysteresis of the steep switch at low voltage for logic memory synergy. The FeFET-based devices can be configured to include a wide hysteresis, a steep hysteresis edge, and high ratio between the two IDS states at VG=0.

Abstract: Disclosed are various embodiments for correlating the measured engagement of attendees to an online conference with the content of the online conference. In one implementation, a timeline is displayed in a user interface for at least a portion of the online conference. The timeline correlates the engagement of the attendees with the content of the online conference based on compiling values measured for engagement parameters of the respective attendees at defined time intervals during the online conference. Input is received identifying a point or interval of the timeline of the online conference. In response to receiving the input, content of the online conference associated with the point or interval is identified and displayed. Alternatively or in addition to displaying content, multiple, different ones of the engagement parameters for the point or interval are identified and have the respective values displayed.

Abstract: Users can participate in various different types of online sessions, such as webinars, massive open online courses (MOOCs), social learning sessions, and so forth. A record of interactions that the user has with an online session is maintained. During the online session, the user may become disengaged from the online session for various reasons, such as the user losing interest in the information being presented, the user becoming sidetracked due to other programs running on his or her computer or phone, and so forth. The techniques discussed herein detect that a user is not engaged in the online session and generate dynamic content to attempt to re-engage the user in the online session. This dynamic content is personalized to the user, and is based on the maintained record of user interactions with the online session.
