I'm not sure what the formal definitions of IsStatic and IsSensor are, but one should ask whether ALL of the following four states are allowable:
IsSensor = true, IsStatic = true
IsSensor = false, IsStatic = false
IsSensor = false, IsStatic = true
IsSensor = true, IsStatic = false
If they are not all valid (as I suspect is the case) then it would be clearer and more correct to create an enum that represents the allowable states (Normal, Sensor, Static), and block public access to the IsStatic and IsSensor members.
Can you explain the intent of IsSensor?
