Abstract: A control device for a vehicle including an operation unit that receives an operation for setting ON or OFF of a plurality of driver assistance functions, wherein at least two or more driver assistance functions among the plurality of driver assistance functions are driver assistance functions classified into a specific group in which the degree of intervention of control for the driving operation is smaller than other driver assistance functions, and the operation unit includes a main switch for collectively setting ON or OFF of the driver assistance functions classified into the specific group.

Abstract: An optical waveguide includes a diamond layer including a first surface, a second surface and a diamond layer including a complex defect; a first clad layer in contact with the first surface; a second clad layer in contact with the second surface and including a polarity; and a metal layer in Schottky contact with the second clad layer.

Abstract: An operational data storage device mounted on an hydraulic excavator is programmed to store operational data including stroke data and movement quantity data. The stroke data represent input operations by the operator of the hydraulic excavator through electric operating levers, and the movement quantity data represent movement quantities of operating members for a front working device equipped with the hydraulic excavator, the operating member being operated according to the input operations. The operational data storage device stores, in an initial state, the operational data in the volatile storage section, generates a save and exit signal if a posture parameter detected at a posture detection sensor included in the hydraulic excavator exceeds a predetermined posture threshold, and responsive to the save and exit signal, switches a write destination of the operational data from the volatile storage section to the non-volatile storage section.
