Provided is a cloud server including an information acquisition unit that acquires location information indicating a location where dangerous driving occurred, a dangerous road determination unit that generates dangerous road information indicating a dangerous area specified according to a plurality of pieces of location information, and a dangerous road information transmission control unit that transmits dangerous road information to a display device.

System, system control method, and information providing server

In a position measurement apparatus, to maintain accuracy of a trajectory even when the frequency of acquisition of absolute position information is reduced, a movement information generation unit generates movement information including a movement distance and a movement direction of a device of interest based on a sensor value, and a reliability generation unit generates reliability information indicating a reliability value of the movement information. An amount of distance correction and an amount of angle correction to be made every predetermined number of steps are determined based on the reliability information and the movement information, and the distance and the angle are corrected every predetermined number of steps starting from the latest already-corrected position information.

Position measurement apparatus, position correction method, and position information acquisition system

A well voltage setting circuit has a P-MOS transistor for applying erase pulse, a first N-MOS transistor for applying a reference voltage Vss to a P-well in a shutdown sequence after erase pulse application, and a second N-MOS transistor for forcing the P-well to the reference voltage Vss during write and read. The first N-MOS transistor has a driving capacity set to about {fraction (1/50)} of that of the second N-MOS transistor, so that a time for forcing the P-well to the reference voltage Vss is long enough to prevent occurrence of local latch-up during erase.
