The knee protection airbag device includes an airbag which protrudes rearward from a deployment opening of a housing upon inflow of inflation gas, and deploys upward to be located in front of knees of an occupant between a vehicular body and the occupant. Target data from a vision system and a radar system, which are used by an object sensing fusion system, are also stored in a context queue. Administrators may specify a set of class files to be treated as a \u201cbundle\u201d. The computing resource is dynamically allocated to the upstream processing element in response to the input rate of the upstream processing element varying. In another embodiment, when a predetermined tank liquid level or volume is reached during filling, the float actuates an inlet closure valve to increase inlet flow resistance, creating a shutoff signal. An upper case of the keybutton section includes a second connecting portion located, along a hinge axis, on the center side of the first connecting portion, and having a cylindrical hole into which an outer cylindrical portion of the dummy hinge is inserted unrotatably, wherein the second connecting portion protrudes from an end of the upper case.
