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 1011 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 method is presented for controlling operation of a power tool having an electric motor drivably coupled to an output spindle. The method includes: receiving an input indicative of a clutch setting for an electronic clutch, where the clutch setting is selectable from a plurality of driver modes; setting the value of a maximum current threshold in accordance with the selected one of the plurality of driver modes; determining rotational speed of the electric motor; determining an amount of current being delivered to the electric motor; comparing the amount of current being delivered to the electric motor to the maximum current threshold; and interrupting transmission of torque to the output spindle when the amount of current being delivered to the electric motor exceeds the maximum current threshold and the rotational speed of the electric motor is decreasing.

Abstract: A power tool includes a motor housing defining a first air chamber with a first air inlet that receives a motor. A handle extending from the motor housing defines a second air chamber with a second air inlet that receives an electronics control module. A third air chamber with an air outlet receives a fan coupled to the motor output shaft. The fan: (a) pulls a first ambient airstream through the first air chamber from the first air inlet and into the third air chamber, bypassing the second air chamber, to cool the motor; (b) pulls a second ambient airstream through the second air chamber from the second air inlet and into the third air chamber, bypassing the first air chamber, to cool the electronics module; and (c) exhausts the first and second airstreams from the third air chamber via the air outlet.

A user selectable and user changeable fluidic plate or fluidic circuit member 152, 372 is configured to allow the user to configure a particular combination of components to create precise 2-D or 3-D spray pattern when spraying or dispensing a liquid product from a trigger sprayer or aerosol sprayer. A spray kit with a user configurable modular nozzle assembly and a method for configuring a trigger or aerosol sprayer for a selected spray pattern includes a reconfigurable nozzle assembly with a replacement nozzle cap 150, 346 having modular fluidic circuit insert element retaining features 170, 172 or 376 and at least one detachable modular fluidic circuit insert element 152, 372 which a user may attach to the fluidic modular element retaining nozzle cap 150, 346.

Abstract: For those spray applications that use a fluidic oscillator of the type that generates a spray by having a pressurized liquid flow through the oscillator and exhaust into a surrounding environment, and where such an oscillator has a boundary surface which has fabricated into it a channel in the form of what is referred to herein as fluidic circuit, an improved enclosure for this oscillator includes: a body having an interior and an exterior surface, wherein a portion of this interior surface is configured to attach to the oscillator boundary surface so as to form with the oscillator's channel an enclosed pathway through which the to-be-sprayed liquid may flow, and wherein a segment of this interior surface is configured so as to yield specified properties of the resulting spray.

Abstract: A fluidic nozzle, for use with a trigger spray applicator that issues a desired spray pattern of fluid droplets, and wherein the applicator has a liquid delivering orifice and an exterior surface proximate the orifice that is configured to receive a spray nozzle, includes in a first preferred embodiment a member having a front and a rear surface and a passage that extends between these surfaces. A portion of this passage is configured in the form of a fluidic circuit, and the configuration of this fluidic circuit is chosen so as to provide the desired spray pattern. Additionally, the passage's rear portion may be configured so as to allow this member to fit on that portion of the spray head which is configured to receive a spray nozzle.
