Abstract: A controller for use with a mobile device is provided. The controller includes a video game controller; and a mobile device holder including a frame, a lock member, and a spring. The frame is pivotably coupled to the video game controller to rotate between a range of setting angles with respect to the video game controller. The frame member is coupled to the lock member via a spring, such that the lock member is slidably moveable to a retracted and an extended configuration. The lock member is biased toward the retracted configuration by the spring to retain the mobile device in the mobile device holder during use. Other related controllers and systems for use with mobile devices are also provided.

Abstract: Disclosed is a coating system for the selective application of coatings to substrates to apply a uniform coating to selected areas of the substrate without the need for masking. The system comprises a first coating applicator for coating large areas of the substrate, a second coating applicator for coating small areas of the substrate, a motion and positioning system for both coating applicators and a system controller. Also disclosed is an ultrasonic spray coating system comprising an ultrasonic transducer with spray forming head, integrated fluid delivery device with air and liquid supply passage ways, support brackets and an ultrasonic power generator.

Abstract: A printed circuit board ("PCB") is moved on a conveyor towards an ultrasonic spray head ("head") that is mounted below the PCB on a guide rail. The guide rail and the direction of motion of the PCB define an acute angle. When the PCB reaches a predetermined position, the head begins a motion across the PCB, spraying a rectangular swatch of soldering flux. The velocity of the head is controlled such that the swatch of flux is substantially perpendicular to the direction of motion of the PCB. After spraying, the head deactivates and reciprocates back across the PCB such that no flux is sprayed. The cycle repeats after a predetermined delay whereby adjacent swatches of flux do not substantially overlap.
