Abstract: Various examples described herein relate to an HMD which comprises an HMD body positioned against a face of a user which includes an IMU to track user location data in an environment. The HMD also comprises a detachable headband assembly including a tracking feature module to construct a map of the environment based on the user location data. The HMD further includes a mechanical mount feature attaching the detachable headband assembly to the HMD body. The mechanical mount feature includes a connection interface to exchange the user location data between the IMU in the HMD body and the tracking feature module in the detachable headband assembly.

Abstract: Various examples described herein relate to a head mountable device (HMD) which comprises an input device to receive captured user data, a connection interface to exchange the user data with a host device, a privacy data switch to route the user data between the input device and the connection interface in the HMD, and a controller. The controller determines whether the user data is restricted data, directs the privacy data switch to block the exchange of the user data when it is determined that the user data is restricted data, and directs the switch to allow the exchange of the user data when it is determined that the user data is not restricted data.

Abstract: A computing system for supporting a plurality of different types of memory devices includes a memory voltage regulator. The memory voltage regulator adjusts a supply voltage to a requisite voltage for a detected memory device based on serial presence detect (SPD) data. The computing system further includes a memory controller that supports a plurality of types of memory devices. The memory controller receives data regarding the type of the detected memory device, and controls input/output signals relative to the type of the detected memory device based on the SPD data and the GPIO data of the detected memory device.

Abstract: Example implementations relate to detection circuits. In one example, a detection circuit includes a power supply, a transistor coupled to the power supply, a port coupled via the transistor to the power supply, where the port is to transmit power received via the transistor from the power supply to a corresponding port included in an external device when the corresponding port is coupled to the port, and a detection circuit to detect a voltage between the port and the corresponding port when the port is coupled to the corresponding port and interrupt, via the transistor, power supplied to the port when the detected voltage satisfies a threshold voltage.
