Abstract: Various embodiments relate to an electronic device with a first panel and a second panel coupled by a hinge mechanism. The electronic device may include a first wire that communicatively couples components of the first panel with components of the second panel. The wire may pass through the hinge mechanism, and be tensioned by a tensioning mechanism that provides tension to the first wire when the electronic device is in an open position and a closed position. Other embodiments may be described and/or claimed.

Abstract: Techniques for overlay components for compute devices are disclosed. In one embodiment, an overlay component on a base portion of a compute device can be moved from a folded or closed position (in which it does not cover the keyboard) to an unfolded or open position (in which it covers part of the keyboard). The base portion includes a touch sensor that allows the overlay component to be used as a touch surface. In another embodiment, an overlay component of a compute device is movable from one position adjacent a display of the compute device to another position adjacent a base of the compute device. The overlay component is electrically switchable from a transparent state to an opaque state, allowing the display to be seen through it in one position and allowing it to be used as an opaque drawing surface in another position.

Abstract: Systems, apparatus, articles of manufacture, methods are disclosed to reshape fan noise of a fan of an electronic device. An example system includes a microphone to detect a first acoustic signal including fan noise. The example system also includes a processor to: identify a tone in the first acoustic signal; and determine a gain to add to the first acoustic signal to mask the tone. In addition, the example system includes a sound transducer to present a second acoustic signal including the gain.

Abstract: The techniques taught in this application include, generally, a brush stylus that includes a number of active bristles. When the brush stylus is in contact with a touchscreen on the computing device, the active bristles provide data to the brush stylus, a computing device the other brush stylus, or both.

Abstract: Systems and methods for the use of a brush stylus are provided herein. In one example, a system includes a brush stylus, wherein the brush stylus includes a plurality of active bristles. The active bristles provide data to the brush stylus, a computing device the other brush stylus, or both, when the brush stylus is in contact with a touchscreen on the computing device.

Abstract: Embodiments are generally directed to a touch sensitive screen with dynamically modifiable writing surface. An embodiment of a display includes a dynamically modifiable writing surface, the writing surface including one or more configuration mechanisms; a touch sensitive element coupled with the writing surface; and a display element coupled with the touch sensitive layer, wherein the one or more configuration mechanisms are configurable to modify one or more characteristics of the writing in response to an activation received by the display.

Abstract: Techniques for tuning in a wireless power transmitter in a system, method, and apparatus are described herein. An example of a wireless power transmitter may include a transmitter coil configured to generate a magnetic field for wirelessly charging a battery, and a tuning circuit coupled to the transmitter coil configured to retune the transmitter coil in response to a reactance shift of the transmitter coil. The wireless power transmitter may also include a tuning control circuit to detect the reactance shift and control the tuning circuit to retune the transmitter coil. The tuning control circuit is to detect the reactance by measuring a drain voltage of a power amplifier.

Abstract: In one example an electronic device comprises a first section comprising a first image input device to generate a first image output, a second section comprising a second image input device to generate a second image output, a hinge assembly to couple the first section and the second section such that the second section is rotatable about the first section and a controller comprising logic, at least partially including hardware logic, to determine when the hinge assembly is in a position in which the first section and the second section are substantially coplanar and in response to a determination that the hinge assembly is in a position in which the first section and the second section are substantially coplanar, route the first image output and the second image output to a depth sensor module. Other examples may be described.
