  • Patent number: 11982539
    Abstract: A display system applied to a vehicle includes a navigation device guiding a route to a destination and a display control device displaying multiple route guidance contents in superimposed manner on a road surface using a head-up display. When the navigation device determines that a first route guidance and a second route guidance included in route guidance information are successive guidance, (i) the navigation device concurrently displays images of the first route guidance and the second route guidance, and (ii) the display control device activates display of a first guidance content that performs the first route guidance, and then activates display of a second guidance content that performs the second route guidance after deactivating the display of the first guidance content.

  • Patent number: 11933234
    Abstract: An engine is provided with a turbo charger including a wastegate valve. A first setpoint of opening of the wastegate valve is set in accordance with a target boost pressure. While a difference between the target boost pressure and a real boost pressure is large, the opening is controlled to a second setpoint, wherein the second setpoint is smaller than the first setpoint. While the opening is controlled to the second setpoint, it is determined whether a condition for limitation is satisfied in which an intake air quantity is above an intake air quantity criterion and an engine rotation speed is above an engine rotation speed criterion. When the condition is satisfied, the opening is controlled in a direction to increase from the second setpoint. The engine rotation speed criterion decreases as the intake air quantity increases. The intake air quantity criterion decreases as the engine rotation speed increases.

  • Publication number: 20230096511
    Abstract: A medication support apparatus includes a storage, a medicine delivery part, an extraction device, a transfer device, a pack information reader, and processing circuitry. The storage stores a medicine pack with first medication-related information. The medicine pack is arranged at a specific position in the delivery part. The extraction device extracts the medicine pack from the storage. The transfer device transfers the medicine pack extracted from the storage to the specific position in the delivery part. The pack information reader reads the first medication-related information before the transfer device transfers the medicine pack extracted from the storage to the specific position in the delivery part.
