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.

Technologies for interfacing an input overlay device with a touch screen of a computing device are disclosed. A computing device includes a touch screen and at least one processor to execute instructions to: determine parameters associated with an input overlay device overlying the touch screen, the input overlay device separate from the computing device, the parameters to identify a first area of the touch screen and a second area of the touch screen different than the first area, the first area corresponding to an area of the touch screen covered by the input overlay device; detect a position of a touch on the touch screen; if the position of the touch is in the first area, determine an input for the computing device based on the position of the touch; and if the position of the touch is in the second area, ignore the touch.

Technologies for interfacing an input overlay device with a touch screen compute device

Technologies for interfacing an input overlay device with a touch screen display of a compute device are disclosed. A compute device may detect that an input overlay device has been placed on top of its touch screen display. After detecting the input overlay device, the computing device determines one or more parameters for the input overlay device. The computing device may then detect an additional touch on the portion of the touch screen display currently covered by the input overlay device. The compute device can then determine an input of a user based on the position of the touch and the one or more parameters of the input overlay device.

Technology for an electronic circuit is described. The electronic circuit can include one or more timed general-purpose input/output (GPIO) pins and a controller. The controller can receive touch sensor data pulses from a plurality of touch sensor integrated circuits (ICs) that are each communicatively coupled to the electronic circuit. A first touch sensor data pulse received from a first touch sensor IC in the plurality of touch sensor ICs can be time synchronized with a second touch sensor data pulse received from a second touch sensor IC in the plurality of touch sensor ICs using the one or more timed GPIO pins. The controller can combine the touch sensor data pulses received time synchronously from each of the plurality of touch sensor ICs to produce joint touch sensor data. The controller can perform joint processing of the joint touch sensor data.

Dynamic on-demand joint processing of touch sensor data from multiple independent touch sensors at an electronic circuit

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.

Power-efficient touch input processing

Methods and apparatus to implement aging compensation for emissive displays with subpixel rendering are disclosed. An example apparatus includes a converter to convert red-green-blue (RGB) data to subpixel rendering (SPR) data. The RGB data is indicative of an image to be rendered on an emissive display screen. The apparatus includes a compensator to apply pixel correction values to the SPR data to generate corrected SPR data to compensate for pixel degradation. The apparatus further includes a usage accumulator to track pixel usage based on the corrected SPR data. The apparatus also includes a correction calculator to calculate the pixel correction values based on the pixel usage.

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.

System standby emulation with fast resume

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.

Fast inking a touch display

Methods and systems may include a human interface device (HID) and logic to place the HID in a blocked state in response to a request to power off the system. The logic can also use a speculative start-up heuristic to establish one or more subsequent operating states for the system while the HID is in the blocked state, wherein the background automatic state transitions may maximize battery life when a user is not present. In addition, the HID may be removed from the blocked state in response to a request to power on the system. Accordingly, the speculative start-up heuristic can make system 'ready-to-use' before the user actually interacts with any inputs (e.g. power button, or touch screen) of the system.

Speculative system start-up to improve initial end-user interaction responsiveness

Described herein is an alteration of the normal reset sequence of a programmable microprocessor to perform a cryptographic verification of a block of memory before executing any instructions from the memory. A programmable processor initializes its state, then computes and verifies a hash of a boot code region of memory before executing any user instructions in the memory. Systems using similar processors, and software to control such a processor's operation, are also described and claimed.

Method and apparatus for verifying authenticity of initial boot code

In one embodiment, the present invention provides for extended memory protection for memory of a system. The embodiment includes a method for associating a protection indicator of a protection record maintained outside of an application's data space with a memory location, and preventing access to the memory location based on the status of the protection indicator. In such manner, more secure operation is provided, as malicious code or other malware is prevented from accessing protected memory locations. Other embodiments are described and claimed.

Providing extended memory protection

A programmable processor calculates a hash value of a memory region, then monitors program operation to detect a security monitoring system initialization. The hash value is added to extend a security measurement sequence if the security monitoring system initialization clears a security state. Processors that implement similar methods, and systems using such processors, are also described and claimed.

Method and apparatus for establishing processor as core root of trust for measurement

A programmable processor initializes its state, then computes and verifies a hash of a boot code region of memory before executing any user instructions in the memory. Systems using similar processors, and software to control such a processor's operation, are also described and claimed.
