Patent number: 11917888Abstract: Cameras are located within the display area of a display. In-display cameras allow for thinner display bezels. In-display cameras allow for the creation of ultra-high resolution images. The ability to capture an object from multiple perspectives allows for holographic image recording and playback. Multiple views of an image can be captured with varying depths of focus, allowing an image's depth of field to be adjusted during post processing. In-display cameras can also be used for user authentication, touch detection and three-dimensional gesture recognition. Thermal sensors located within the display area allow for control of the display temperature, improved control over system performance, and compensation for micro-LED degradation that can occur due to aging or increased temperature. Microlens assemblies located above pixels can adjust the viewing cone angle of the display or a portion of the display and microassemblies located under individual pixels or pixel arrays can adjust a viewing angle.Type: GrantFiled: November 5, 2021Date of Patent: February 27, 2024Assignee: Intel CorporationInventors: Ramon C.

Patent number: 11849279Abstract: Microphones are located between pixel display elements (e.g., micro-LEDs and OLEDs) in a display. Display-integrated microphones allow displays to have thinner bezels. Audio processing components can also be incorporated into the display and allow audio processing offloading from processors external to the display. Arrays of microphones allow for the beamforming of received audio signals to enhance the detection of sound from remote audio sources. Piezoelectric elements can also be integrated into a display to allow for localized haptic feedback. Integrated piezoelectric elements can act as speakers and beamforming techniques can be used to activate sets of piezoelectric elements in coordination to direct sound to a specific location external to the display. Piezoelectric elements can aid in display thermal management by creating acoustic waves to move heated air within a display to create a more uniform thermal profile within the display or to remove excess heat from the display.Type: GrantFiled: April 20, 2021Date of Patent: December 19, 2023Assignee: Intel CorporationInventors: Vivek Paranjape, Satish Prathaban, Vishal Ravindra Sinha, Ramon C.

Patent number: 10551900Abstract: A first optimal CPU frequency that produces minimal power consumption for a CPU/platform combination may be calculated by using an Efficiency Aware Race to Halt (EARtH) algorithm, which ignores the power efficiency curve of the voltage regulator (VR). These results may then be modified by applying the power efficiency curve of the associated VR to determine a second optimal CPU frequency that produces power consumption that is less than the value calculated by the EARtH algorithm.Type: GrantFiled: March 28, 2017Date of Patent: February 4, 2020Assignee: Intel CorporationInventors: Vijayakumar A.

Patent number: 9329656Abstract: An apparatus and method is described herein for reducing noise in a power distribution network for an interface. The power distribution network is characterized. And based on that characterization, worst case patterns for the interface are predicted and avoided. As one example, characterization includes providing a stimulus, such as a step function stimulus, and determining a mathematical function response, such as a step function response. Then, based on the step function response, a resonant frequency for the power distribution network is determined; from which patterns that cause the resonant frequency are identified/predicted. And when identified patterns are detected, they are scrambled or manipulated to avoid causing a worst-case noise scenario in an interface's power distribution network.Type: GrantFiled: March 24, 2014Date of Patent: May 3, 2016Assignee: Intel CorporationInventors: Satish Prathaban, Ramaswamy Parthasarathy, Maynard C.

Publication number: 20160020621Abstract: The present application is directed to a bidirectional voltage converter for multi-cell series batteries. A power module may comprise a battery including at least two cells and a converter module to generate a single-cell voltage and a two-cell series voltage from battery power while controlling charging and/or discharging of the cells to be at substantially the same rate. A converter module may comprise a first capacitor coupled across a first cell, a second capacitor coupled across a second cell and a third capacitor that may be flexibly coupled. When balancing charge and/or discharge rate, the third capacitor may be coupled across the second capacitor for a set on time and then coupled across the first capacitor for the set on time. A variable off time between couplings may be determined based on the difference between the voltage in the third capacitor and first capacitor.Type: ApplicationFiled: July 15, 2014Publication date: January 21, 2016Applicant: Intel CorporationInventors: ANIL BABY, SATISH PRATHABAN
