    Abstract: In a user interface (UI) device, an exclusion part extraction unit excludes an indeterminate part or a dynamically changing part as an exclusion part from a to-be-cached part group among a plurality of UI parts that constitute a screen. A cache information generation unit generates drawing information about the to-be-cached part group excluding the exclusion part, and registers the generated drawing information in a drawing information cache unit. When a screen is drawn using the drawing information about the to-be-cached part group excluding the exclusion part, the drawing information being registered in the drawing information cache unit, the exclusion part combining unit combines drawing information that corresponds to the exclusion part with the drawing information about the to-be-cached part group excluding the exclusion part.

  • Patent number: 9637050
    Abstract: A vehicle collision avoidance assist apparatus is capable of alerting the driver of a host vehicle that is to enter an intersection to the probability of collision or the like at right timing in order to prevent a crossing accident using information acquired from remote vehicles through inter-vehicle communication. The attention of the driver of the host vehicle to the front side including the intersection is increased when a large number of remote vehicles exist around the intersection which the host vehicle is to enter, compared with a case in which the number of remote vehicles around the intersection is small. The vehicle collision avoidance assist apparatus makes the alert, such as a warning, later than reference alert timing (normal alert timing) in consideration of the above situation to suppress excessive alert.
