Abstract: A computer-implemented method of map data processing, comprising generating, for a grid-based representation of map data, raw grid features; building a grid map by reading from a memory that stores the raw grid features; and processing the grid map using one or more post-processing operations including a smoothing operation applied across zero or more grid lines of the grid map according to a rule.

Abstract: A system and method for determining a critical suspension speed of an impeller in a solid-liquid stirred tank belongs to the technical field of critical speed determination. A relationship is established between a voltage of a measurement electrode and a solid-liquid suspension state to avoid the problems of strong subjectivity and large deviation appearing in existing critical suspension speed determination based on empirical formulas and human eye observation. An electrode voltage ratio is taken as a determination criterion, which is only related to a spatial density of solid particles in a liquid phase.

Abstract: The present disclosure provides a fixing device and an image forming apparatus. Fixing device includes a device main body, including a heater, where the device main body includes a driving end connected to a power outputting part of the image forming apparatus and a non-driving end opposite to the driving end; a locking element, disposed on the non-driving end of the device main body; and a chip, including a contact part. When the device main body is installed on the image forming apparatus, the locking element is connected to the image forming apparatus, and the contact part of the chip is electrically connected to the image forming apparatus; and a projection of the contact part of the chip in an axial direction of the heater intersects a projection of the locking element in the axial direction of the heater.
