Abstract: Systems and methods may provide for assuming control over a processor in response to an operating system (OS) request to transition the processor into a sleeping state and transitioning the processor into an intermediate state that has a shorter wake latency than the sleeping state. Additionally, the processor may be maintained in the intermediate state until a wake event is detected. In one example, one or more power lowering operations may be reversed in response to the wake event.

Abstract: An apparatus for fast inking a touch display is described herein. The system for fast inking a touch display can include receiving touch input and generate touch sensor data. The system can include a graphics processing unit (GPU) including a fast inker and a display pipeline. The GPU can transmit human interface device (HID) data generated from the touch sensor data to a writing application memory and the fast inker. The fast inker can convert the HID data into inking data to be sent to the display pipeline through a direct hardware path. The writing application can convert the HID data into inking data to be sent to the display pipeline. The system can also include a touch display to display pixels marked according to the inking data received by the display pipeline.

Abstract: A lid controller hub (LCH) comprising processing components located in the lid of a mobile computing device, such as a laptop, processes sensor data generated by input sensors (microphones, cameras, touchscreen) and provides for improved and enhanced experiences over existing devices. For example, the LCH provides hardened privacy and the synchronization of touch display activities with the display refresh rate, the latter providing for a smoother and more responsive touch experience over existing designs. The LCH enables continuous gestures comprising touch gesture and in-air gesture portions as well as multi-plane gestures in which an initial touch gesture places the device into a mode or context in which it recognizes and acts upon subsequent in-air gestures. Touch operations of a mobile computing device can be based on user presence, user engagement, and a level of user interaction with the device.

Abstract: A method for power-efficient touch input, in which touch sensor data from a touch input is obtained by touch circuitry. Touch sensor data is obtained from touch input at touch circuitry included in a device that also includes a system-on-a-chip (SOC) and a display controller stack outside of the SOC. The touch sensor data is stored in a buffer. When the SOC is in a low-power state, the touch sensor data is communicated to the display controller stack for immediate display.

Abstract: System and techniques for predicting a stylus position while interacting on a surface are described herein. The prediction begins by obtaining a set of points that are derived from a stylus moving on a surface. An artificial neural network (ANN) may be invoked on an input set. Here, the input set is based on the set of points from the stylus. The ANN is configured to output a next point from the input set, and the ANN is trained to minimize angular error for the next point over other errors. Once the next point is provided by the ANN, the next point may be communicated for rendering on a display.

Abstract: A system includes a processor in a lid portion of a computing device. The processor is communicatively coupled to a plurality of input/output (I/O) devices according to a plurality of I/O communication protocols via a first number of wires. The system includes a first memory coupled to the processor to store instructions that can be executed by the processor and cause the processor to receive, from a first I/O device of the plurality of I/O devices, a first message according to a first I/O communication protocol of the plurality of I/O communication protocols, convert the first message to a second message according to a host communication protocol, and send the second message over a bus containing a second number of wires traversing a hinge movably coupling the lid portion to a base portion of the computing device. The second number of wires is less than the first number of wires.
