Abstract: A compressed fluid source assembly may comprise: a pressure cylinder configured to receive a compressed fluid source therein; and a surface acoustic wave (SAW) sensor coupled to an external surface of the pressure cylinder.

Abstract: A flow angle sensor includes a sensing element, a background component connected to and movable with the sensing element, the background component having a marker, a lens adjacent the disk, an image sensor axially aligned with the lens, a light source positioned to illuminate the disk, and an image processing system connected to the image sensor. The image processing system provides an angle of attack output based on a location of the marker sensed by the image sensor.

Abstract: A windshield wiper system includes a wiper arm, a wiper blade attached to the wiper arm, an output shaft attached to an end of the wiper arm, an actuator attached to the output shaft, a controller, a first sensor, a second sensor, and a third sensor. The controller is configured to activate the actuator, causing the output shaft to rotate and thus driving the wiper arm with the attached wiper blade in a sweeping motion across a windshield. The controller is also configured to receive signals from the first, second, and third sensors indicating the position of the wiper arm and the wiper blade.

Abstract: A windshield wiper system (WWS) is provided and includes a wiper blade, a motor assembly and a control system. The wiper blade includes a tip. The motor assembly is configured to drive the wiper blade in a sweep pattern across a windshield. The control system is configured to control the driving of the wiper blade by the motor assembly in accordance with positions of the tip of the wiper blade.
