Ultrasonic water-agnostic touch detection sensor
An ultrasonic touch sensing system that uses both compressional and shear waves for touch and water detection is disclosed. When no touch or water is present, less shear and compressional wave energy is absorbed, so both shear and compressional wave reflections do not have significant amplitude decreases. When a finger is in contact with the sensing plate, both shear and compressional wave energy is absorbed, so both shear and compressional wave reflections have significant amplitude decreases. When water is in contact with the sensing plate, compressional energy is absorbed but little or no shear wave energy is absorbed, so while compressional wave reflections have significant amplitude decreases, shear wave reflections do not. From these amplitudes, a determination can be made as to whether no touch is present on the sensing plate, whether a touch is present on the sensing plate, or whether water is present on the sensing plate. |

Techniques for accurately determining the temperature at various locations of an operating integrated circuit
Integrated circuits (ICs)—depending on a current workload—may exceed thermal cooling budgets. As a result, ICs often implement thermal sensors to measure temperatures at junctions or hot spots along the IC. Due to a distance between the thermal sensors and the various junctions, a thermal offset may be added to the temperature readings from the thermal sensors to more accurately estimate the temperature at the junctions. To account for different workload distributions—e.g., asymmetric or symmetric—the systems and methods described herein may dynamically adjust the thermal offsets. As a result, the efficiency of the IC may be increased as thermal settings for the IC may take into account the ability of the thermal cooling budget to effectively cool the IC under a current operating condition—thereby reducing premature throttling back or shutting down of power to the IC. |
