Abstract: Aspects relate to techniques for controlling signal voltage levels across a wired data link for data communication between apparatuses. A first device can advertise multiple supported signal voltage levels to a peer device connected by the wired data link. The devices can implement the same signal voltage level(s) or different signal voltage levels. The peer devices can compare and select a compatible signal voltage level for data communication. The first device can provide a signal voltage indication signal that is configurable to a plurality of voltage levels corresponding to a plurality of signal voltages. At least one of the plurality of voltage levels can indicate that the first device can operate the data link at a plurality of signal voltages. In some examples, the wired data link can be a peripheral component interconnect express (PCIe) link.

Abstract: Systems and techniques are provided for an adjustable camera system for mouth tracking. An example apparatus can include a housing with an opening formed in a first side of the housing, wherein one or more surfaces of the housing are configured to engage a head of a user; and a structure including a lens configured to receive incident light, wherein the structure is configured to move from a retracted state where at least a portion of the structure is retracted into the opening in the first side of the housing, to an extended state where at least a portion of the structure that includes the lens structure extends from the first side of the housing.

Abstract: A device that includes a board, a package and a patch substrate. The board includes a cavity. The package is coupled to a first side of the board. The package includes a substrate and an integrated device coupled to the substrate. The integrated device is located at least partially in the cavity of the board. The patch substrate is coupled to a second side of the board. The patch substrate is located over the cavity of the board. The patch substrate is configured as an electromagnetic interference (EMI) shield for the package.

Abstract: A method of controlling signal termination includes providing first logic for selectively terminating signals received at a first device on a bidirectional data bus, providing second logic for selectively terminating signals received at a second device on the bidirectional data bus, sending first signals from the first device to the second device on the bidirectional data bus at a first speed, stopping the sending of the first signals, after stopping the sending of the first signals, enabling the second logic and shifting a reference voltage of the second device from a first level to a second level, after enabling the second logic at the second device, sending second signals from the first device to the second device on the bidirectional data bus at a higher speed, and controlling the first logic based on a speed of signals received at the first device on the bidirectional data bus.
