Abstract: A wiper arm assembly has a load member, a wiper arm, and a blade load cam with a cam slot. The load member mates with a joint disposed between first and second ends of the wiper arm. Changes in length of the load member impose a force in a lengthwise direction of the load member. The wiper arm is configured to rotate relative to the blade load cam about an axis proximate to the first end of the wiper arm. The cam slot is configured to vary the length of the load member as a function of a wiper angle in which the wiper angle is defined as the angle between the wiper arm and a starting position of the wiper arm.

Abstract: A multi-element thermocouple circuit includes at least two temperature measuring junctions. A first temperature measuring junction is formed by first and second thermoelements, each of the first and second thermoelements being formed of a noble metal or a noble metal alloy. The second temperature measuring junction, which connects to the distal end of the first thermoelement, is formed by third and fourth thermoelements, neither of which is formed from a noble metal or a noble alloy. A fifth thermoelement connects to the distal end of the second thermoelement and is formed of the same material as the fourth thermoelement. During operation, the distal ends of the third and fourth thermoelements define therebetween a first voltage difference corresponding to a temperature at the second temperature measuring junction, while the distal ends of the fourth and fifth thermoelements define a second voltage difference from which a temperature at the first temperature measuring junction may be obtained.
