  • Patent number: 11914871
    Abstract: An electronic control device includes a nonvolatile memory having allocated two storage areas that are exclusively switchable between an active state and an inactive state, the two storage areas being set such that in a state in which a program is written in the storage area in the active state, a program is written for updating to the storage area in the inactive state in response to an instruction from an external device, followed by switching the storage area in the active state to the inactive state and switching the storage area in the inactive state to the active state. In the electronic control device, when the program written in the storage area in the active state differs from the program written in the storage area in the inactive state, the program written in the storage area switched to the active state is copied to the storage area in the inactive state.

  • Publication number: 20220272963
    Abstract: A cell cryopreservation method including adding a 1 volume % of a composition comprising 0.01 wt % to 20 wt % of a sophorose lipid to cells in a cell culture medium just before or up to 6 hours before cryopreserving the cells; and cryopreserving the cell culture medium, wherein the composition improves cell viability after cryopreservation compared to cells that are cryopreserved with a similar composition that does not contain the sophorose lipid.

  • Patent number: 10960833
    Abstract: A vehicle control apparatus according to the present invention includes a main electronic control unit, and a sub electronic control unit capable of mutual communication with the main electronic control unit. The main electronic control unit outputs a signal for preventing timeout to at least one of the external device and the sub electronic control unit, when mediating data communication between the external device and the sub electronic control unit.

  • Publication number: 20200045955
    Abstract: This composition can be easily added when cryopreserving cells and improves cell viability. 1 volume % of the composition containing 0.01 wt % to 20 wt % of a sophorose lipid is added just before or up to 6 hours before cryopreservation and cells are stored. This composition can improve cryopreservation cell viability as it reduces freezing damage to cells. With this composition, cells can be stored without using DMSO and blood serum. This is a simple and inexpensive storage method as it does not require fine control of the freezing rate during cell cryopreservation.

  • Patent number: 7765041
    Abstract: An electronic control apparatus for a vehicle having an engine control unit 114 controlling an electronically-controlled throttle of an engine and a valve control unit 141 controlling a variable lift mechanism 112 that varies a lift amount of an intake valve are provided. Information of a target lift amount and an actual lift amount is transmitted/received between these control units. Each of the control units diagnoses a state of data transmission from the other control unit, transmits the diagnosis result to the other control unit and, when the diagnosis result of itself and/or the diagnosis result of the other control unit shows an abnormal state, moves to the mode of a fail-safe operation.
