  • Publication number: 20210074081
    Abstract: The invention provides a control unit and a control system for a vehicle capable of reducing a workload of deleting a record of information of an unintended event detected by a certain control unit by preventing the other control unit from recording the information of the event. Control units (50a to 50d) that are mounted on the vehicle and connected in a mutually communicable manner each include an event processing section (55). The event processing section (55) executes one or both of processing to switch whether to notify a recording request of the information of the event and processing to switch necessity/unnecessity of recording of the information of the event.

  • Patent number: 10641790
    Abstract: Provided is a scanning probe microscope being able to shorten an observation time of a minute observation object. Main measurement is performed to acquire a surface image of a sample based on a detection signal in a measurement range of a plurality of lines by repeating, for each line, processing of scanning a cantilever at predetermined second intervals in a Y-direction after acquiring the detection signal at predetermined first intervals while scanning the cantilever on a line having a predetermined length along an X-direction. Preliminary measurement is performed to acquire a surface image of the sample by acquiring the detection signal at intervals wider than the first intervals or scanning the cantilever in the Y-direction at intervals wider than the second intervals before the main measurement, the surface image of the sample being coarser than the surface image in the main measurement.

  • Patent number: 10598691
    Abstract: A scanning probe microscope includes a light source, a detector, a housing, an opening and closing door, an opening and closing sensor, a control unit, and the like. The opening and closing door is provided in the housing. The control unit 16 also functions as the light intensity change processing unit 164. In the scanning probe microscope, when the opening and closing sensor detects opening and closing of the opening and closing door, the light intensity change processing unit automatically changes the intensity of light irradiated from the light source based on a detection result of the opening and closing sensor. Therefore, it is possible to omit light intensity adjustment work performed manually by the user. As a result, the workability of the user when using the scanning probe microscope 1 can be improved.
