Power management for Universal Serial Bus (USB) type-C port
A power management scheme for USB systems. For Mobile systems that has re-timer, a handshake is used between power delivery (PD) controller, re-timer and embedded controller (EC) so that the PD controller can end higher wattage power contract on USB-C connector after TBT/USB4 link is in low power (CLd/U3) and during system low power transition allowing Dynamic Platform and Thermal Framework (DPTF) framework to boost CPU performance and enhance battery capacity respectively. The same solution can be extended to desktop segment to allow PD controller to lower the USB-C power contract with connected devices before switching to standby rail. For mobile systems that are without re-timer, a handshake is used between BIOS, PD controller and EC so that PD controller can end higher wattage power contract on USB-C connector after TBT/USB4 link is in low power (CLd/U3) and during system low power transition. |

High-resolution radar target signature smearing correction
A radar apparatus at a vehicle may transmit a set of radar energy that is reflected off an object after which the reflected radar energy may be received at the radar apparatus. When relative motion of a radar apparatus and an object include movement in two different directions, power of the reflected radar signals may be spread out in a manner that makes data associated with the reflected radar signals difficult to interpret. This spreading out of the radar signals can make mappings of the received radar data appear to be smeared or distorted. To compensate for this smearing effect, mappings of this smeared radar data may be compared with curves from which compensation factors may be identified. These compensation factors may allow a processor to perform calculations to generate updated mappings of the radar data that may allow the processor to more accurately identify characteristics of the object. |
