Provided are a neurovascular unit (NVU)-on-a-chip and a method of fabricating the same, which 3-dimensionally integrates various human brain cells in a microfluidic platform by using a brain cell co-culture technique so as to simulate a similar environment to the human brain in vitro. The NVU-on-a-chip includes an extracellular matrix (ECM) simulation material () in a gel state; and at least one channel () which passes through the ECM simulation material () and perfuses a culture medium, in which the ECM simulation material () contains a plurality of types of human brain cells on an outer side of the channel (), a brain microvessel endothelial cell lining () is formed on an inner side of the channel (), and the plurality of types of human brain cells and the brain microvessel endothelial cell lining () contact each other through the channel () to simulate a blood brain barrier (BBB) of a human brain and a neurovascular unit (NVU) of the human brain including the BBB.

Various embodiments of a warning indicator for use with wiper blades are provided. In one embodiment, the warning indicator has a housing, a counting unit disposed in the housing, an indicating unit exposed on the housing and an electrical source. The housing is coupled to an oscillating wiper blade of a windshield wiper device. The counting unit is configured to detect oscillating movements of the wiper blade one at a time. The counting unit is configured such that an oscillating number of the wiper blade is accumulatively increased. The indicating unit indicates a warning under control of the counting unit when the oscillating number comes to a predetermined value. The electrical source supplies an electrical power to the counting unit and the indicating unit.
