Abstract: A low profile, integrated camera wash nozzle assembly 1010 is readily and unobtrusively integrated into a vehicle's exterior trim surfaces 1420 to make a more visually appealing exterior design while not compromising spray performance. A system and nozzle assembly (e.g., 710, 810, 1010) for cleaning an exterior objective lens or wide-angle sensor's exterior surface 1022 to remove accumulated debris sprays washer fluid at a selected shallow angle which is substantially transverse to the lenses central viewing axis 1050. A low-profile conformal housing fixture 101 1 is adapted to receive and aim a very compact fluidic circuit insert 1200 that can generate a wide spray which substantially covers the lens surface, despite being very close to the edge of the lens 1022.

Abstract: A burner or torch system for mixing fuel with air includes a fluid oscillator for forming a jet or sheet of fuel and oscillating the jet in ambient air downstream of the fluid oscillator. This mixes air with fuel and achieves a combustible mixture a distance spaced from any physical structure of the burner or torch whereby a flame front of burning combustible mixture has a shape and distance from the fluid oscillator which is determined by the sweep angle, wave pattern and frequency of the fluid oscillator. Various forms of fluidic oscillators are disclosed.

Abstract: A method and apparatus of maximizing transfer of thermal energy to or from an oscillating or swept air jet (10) propagated over a windshield (21). The air jet is projected through short distances in ambient from a nozzle (11) properly aimed at said windshield. The wavelength μ of the oscillating or swept jet is caused to be greater than the nozzle distance from windshield and smaller than the length extent of windshield in the direction of air jet propagation across it whereby there is less of loss or gain of thermal energy from said air jet in the space between said nozzle and said windshield and a maximum transfer of thermal energy between the windshield and air jet by lessening the thickness of any insulating boundary layer.
