Abstract: Systems, methods, and apparatuses can detect whether an electrical cable between a source device and a sink device has become disconnected. The source device and/or the sink device can be compliant with a version of a Universal Serial Bus (USB) standard, for example, USB 3.x. These systems, methods, and apparatuses can monitor peak voltage swings of data signals flowing between the source device and the sink device. The peak voltage swing of these data signals can be at a first value when the electrical cable is connected to the source device and the sink device or at a second value greater than the first value when the electrical cable is disconnected from the source device or the sink device. The peak voltage swing can switch from the first value to the second value in response to the electrical cable being disconnected from the source device or the sink device.

Abstract: Systems and methods are disclosed to enable performance of a lens distance test in head-mounted displays (HMDs) to determine the distance between a user's eye and a lens of the HMD (e.g. the display lens in a virtual or augmented reality device). In embodiments, the HMD is configured to determine a current pose of the eye based on a series of captured eye images. The pose information is used to determine the distance from the apex of the cornea to a closest point on the lens. If the determined distance is too small or too large, an alert or notification is generated instructing to adjust the HMD or change the light seal to achieve better distancing, in order to reduce the risk of eye injury and/or improve user experience. In embodiments, the lens distance test may be repeated during a user session to reevaluate and/or monitor the lens distance.

Abstract: Structures, methods, and apparatus for protecting interconnections between components and boards in an electronic device from damage resulting from a physical shock. This damage can occur due to differential tensile forces being applied between the component and the board during a drop or other shock event. An example can reduce or prevent damage by providing differential compression forces between the component and board that can cancel differential tensile forces between the component and board during the shock event. Another example can reduce or prevent damage by reducing differential tensile forces between a component and board. Another example can secure a component to the board to directly reduce the differential force in order to prevent damage.

Abstract: Methods and apparatus for correcting the gaze direction and the origin (entrance pupil) in gaze tracking systems. During enrollment after an eye model is obtained, the pose of the eye when looking at a target prompt is determined. This information is used to estimate the true visual axis of the eye. The visual axis may then be used to correct the point of view (PoV) with respect to the display during use. If a clip-on lens is present, a corrected gaze axis may be calculated based on the known optical characteristics and pose of the clip-on lens. A clip-on corrected entrance pupil may then be estimated by firing two or more virtual rays through the clip-on lens to determine the intersection between the rays and the corrected gaze axis.
