  • Publication number: 20230266962
    Abstract: A control system for a vehicle includes: a power source; a first power line; a second power line; a first relay; a second relay; at least one first control device; and at least one second control device. The first control device is configured to transmit a trigger signal to the second control device on condition that the first control device has detected that the first relay has been turned from off to on, and enable a first update program after transmitting the trigger signal. The first update program is an updated version of the first current program. The second control device is configured to enable a second update program on condition that the second control device has received the trigger signal from the first control device. The second update program is an updated version of the second current program.

  • Patent number: 11022907
    Abstract: An image forming apparatus includes a first image forming unit for forming a first image on a sheet using a first toner. The first toner includes at least two fluorochromes which have a fluorescence peak in a wavelength range different from one another. A second image forming unit is configured to form a second image on the sheet using a second toner. The second toner includes a visible colored pigment. A softening point temperature of the first toner, as measured by differential scanning calorimetry, is higher than a softening point temperature of the second toner, as measured by differential scanning calorimetry.
