Abstract: Disclosed embodiments are related to techniques for powering compute platforms in low temperature environments. Embodiments include a preheating stage that is added to a power up sequence. The preheating stage may include a force-on stage and a force-offstage. During the force-on stage, all power rails of target components are forced to an ON state so that the target components consume current. When a target operating temperature is reached, the power rails of the target components are turned off, which causes the target components to revert back to their initial (pre-boot) state allowing the normal boot process to take place. Since the target components are now heated up, the boot process can execute faster than when the target components were cold. Other embodiments may be described and/or claimed.

Abstract: The present invention discloses an urban traffic velocity estimation method based on multi-source crowd sensing data. This method, based on roadside pedestrian data and road navigation data collected by smart phones, obtains a final estimated velocity through the steps of missing data filling, self-view velocity aggregation and multi-view velocity fusion. This fine-grained large-scale urban traffic velocity estimation method can achieve velocity estimation on all types of roads, including suburban road sections and paths, instead of just focusing on main roads in a city center. According to the present invention, based on data driving, the urban traffic velocity estimation method does not need to install additional devices on roads, and is low in cost and high in universality. Compared with the prior art, the urban traffic velocity estimation method has higher practicability, theoretical property and applicability, and is of great significance for improving traffic management and planning.
