Newer model vehicles typically have touchscreen displays, but some vehicles may have displays without an associated touchscreen. In those cases, …

Encrypted Memory Access By Peripheral Devices Of A Confidential Virtual Machine, Marc S. Orr, Rachit Mathur, Erdem Aktas, Andrew Honig

Defensive Publications Series

A confidential virtual machine (CVM) uses a hardware-rooted key to encrypt customer data written to memory. For enhanced security, the CVM makes the plaintext-to-ciphertext map depend on the physical address (PA) of the memory location. Peripheral devices operate not in PA space but in input-output address space. Currently, peripherals can only perform memory accesses without encryption, or need to use a two-pass, high-latency, power-intensive encryption procedure involving a transport key distinct from the hardware-rooted key.

This disclosure describes techniques to enable a peripheral device of a confidential virtual machine to access encrypted memory using a single encryption pass. The techniques …

Automatically Splitting And Routing Foreground And Background Audio To Different Output Devices For Immersive Surround Sound, D Shin

Defensive Publications Series

In the head-lock mode, headphones operate such that the directionality of sound sources within the audio is locked to the location of the headphones and not to locations within a physical scene. The head-lock mode can reduce the realism of the surround sound simulation due to failure to take into account the rotation or tiling of the user’s head to adjust the directionality of the sound sources. This disclosure describes techniques to automatically provide a more physically accurate surround sound experience by splitting the foreground and background parts of an audio stream. The foreground audio is routed to the user’s …

Sleep Mode Activation Based On Detecting Laptop Lid State Via Ultrasonic Ping Signal, D Shin

Defensive Publications Series

Sleep mode conserves laptop battery when the device is not in active use. A quick mechanism to put a laptop in sleep mode is simply to close the lid. Most laptops include a Hall Effect magnetic sensor to detect whether the laptop lid is closed. This imposes additional costs and can increase thickness. This disclosure describes the use of existing speakers and microphones of a laptop to detect lid state. An inaudible ultrasonic ping is emitted via built-in speakers and reflection of the ping is captured using the built-in microphone(s). The sound signature is analyzed to determine lid state. Distinct …

Audio Signature Based Hotkeys For Smart Glasses And Other Wearable Devices, Joshua Moore, D Shin

Defensive Publications Series

Techniques are described for augmenting user interaction with smart glasses or other wearable devices that receive audio input. In a configuration phase, a user records an audio signature and links the audio signature to action(s) and/or features to be activated when the audio signature is detected. The audio signature patterns are parameterized based on a number of audio events, a time interval between the events, and the type of audio events. Entropy aware coding is utilized such that the most commonly utilized features are linked to audio signature patterns (codes) that are easier to generate. A trained local audio event …

Adjusting Augmented Reality Text Display For People With Presbyopia, Michael David Lubrano

Predictive Activation Of Device Components Based On Partially Decoded Command, D Shin

Defensive Publications Series

Users often invoke a virtual assistant to quickly accomplish routine tasks that require the corresponding components of a device to be woken up from an idle state prior to performing the desired action. Activating the components introduces an inherent latency that can noticeably raise the task completion time and degrade the user experience. This disclosure describes techniques to reduce the latency involved by proactively waking up idle device components by predicting the intended task based on the initial words in a user’s spoken command to a voice based virtual assistant. The net effect of starting the wake-up process based on …

Identifying A Color With Sufficient Contrast Against Two Distinct Background Colors, Peter Kasting, Peter Boström

Defensive Publications Series

A good user interface design provides user interface elements that contrast sufficiently with their surroundings. While color contrasting is relatively simple to do when there is one surrounding color, when choosing foreground colors between two background colors, the foreground must simultaneously contrast with both background colors. Given two background colors and an initial foreground color, this disclosure describes techniques to automatically select a foreground color that contrasts with both background colors and is similar in hue to the initial foreground color. The choice of colors can be constrained to a palette of valid colors grouped by similar hue. Given a …

Machine Learning Driven Under Display Ambient Light Sensor Calibration, D Shin

Defensive Publications Series

An under-display ambient light sensor (ALS) can be employed in devices that have small bezels which cannot accommodate an ALS. However, the lux detected by an under-display ALS can deviate from the true lux levels of the environment because of the impact of the light from the display pixels. This disclosure describes the use of a calibrated machine learning model to obtain the true lux measurement for ambient light by adjusting the value measured by the ALS to compensate for the influence of display light.

Upscaling Image Resolution Using Optical Zoom And Rotation, Dmitrii Boiarshinov

Defensive Publications Series

This disclosure describes techniques to capture images or videos of high resolution with cameras and optical components of ordinary size and specification as found in typical webcams or smartphones. Per the techniques, one or more cameras perform an optical zoom to sections of the field of view, capturing high-resolution sub-images of the field of view. The cameras raster across the field of view, rotating as necessary, to capture high-resolution sub-images that are integrated to reconstruct a high-resolution image of the entire field of view.
