Physical Device (umbel:SubjectConcept)
device, apparatus, apparatuses, devices, equipment, implement, implements, instrument, instruments, physical device, physical devices
Definition
A specialization of SolidTangibleArtifact and ObjectWithUse. Each instance of PhysicalDevice is an artifact with a relatively rigid, set shape, designed for a specific use or to perform a specific function. Specializations of PhysicalDevice thus include (among others) RoadVehicle, Motorboat, HandTool, and PlumbingFixture. Note that artifacts which are only to be viewed or can only be "used" in a very loose or metaphorical sense, such as instances of Buoy, Sculpture, FlowerBed, or Billboard, are not instances of PhysicalDevice. Moreover, artifacts which have a specific use or function, but which do not have a relatively rigid, set shape are not instances of PhysicalDevice; for this reason, neither GasolineFuel nor AntiFreeze are specializations of PhysicalDevice.
