Abstract: A wiper apparatus includes a wiper axis interface (102) configured for mounting a wiper assembly to a wiper drive (106). A lower wiper arm (110) extends from the wiper axis interface to a wiper mount (112) that is configured to connect the lower arm to an upper arm (114). A first end (124) of the lower wiper arm proximate the wiper axis interface has a first airfoil profile and wall thickness. A second end (126) of the lower wiper arm proximate the wiper mount has a second airfoil profile and wall thickness. An intermediate portion (128) of the lower wiper arm extending between the first and second ends has a transitioning airfoil profile and thickness that transitions from the first airfoil profile and wall thickness to the second airfoil profile and wall thickness.

Abstract: A liquid level indicator (14) used for determining liquid levels in a sealed container (10) includes a heat source (24) bonded to the container (10), a first temperature sensor (26) mounted on the container (10) adjacent the heat source (24), and a second temperature sensor (28) mounted on the container (10) spaced from the heat source (24). The temperatures at the first and second temperature sensors are sensed while the heat source (24) is operating, and the differential in the temperatures is measured and used to control power to the heat source (10). Changes in the differential in temperature between the first (26) and second (28) temperature sensors indicates when the heat conductivity between the first (26) and second (28) temperature sensors changes, due to presence or absence of a liquid in the container (10) at the level of the temperature sensors (26, 28).
