The present disclosure generally relates to systems and devices for spraying fluid materials such as paints, stains, and the like, and more specifically, but not by limitation, to a fluid level indicator for an airless fluid sprayer. In one example, an airless fluid sprayer is provided and includes a fluid container, a controller, and a fluid level indication module implemented by the controller to generate an indication of a level of fluid material in the fluid container.

A two (or more) piston pump system () is provided with both pumps () being crank () driven. The system does not have a mechanical camshaft, but a software algorithm, which acts like one in controller (). The algorithm will LEARN and create a unique speed profile, which will mimic the mechanical camshaft. For practical purposes the speed profile of output gear is called Cam profile with software acting as an imaginary camshaft. The algorithm utilizes Crank Angle Estimation, Learn Curve Generation, Smoothing and Advance Timing Calculation.

An adjustable angle cutting jig device and associated method of using the device for use with a table saw having a circular blade, a rip fence and a miter groove is disclosed. The device comprising the interconnected elements of a rip fence guide, a first shank, a second shank, a cross member, a first rotating arm, a first threaded bolt, a second rotating arm, a second threaded bolt, cross brace, a first angle guide, a first wingnut, a second angle guide, a second wingnut, and at least one clamp. The method of using comprises the steps of adjoining, affixing, aligning, angling, cutting, fastening, grabbing, identifying, inserting, loosening, obtaining, placing, pushing, raising, sliding, tightening, turning, and untightening.

An apparatus and method for treating sleep apnea includes a bilevel flow generator having an alternating current (AC) synchronous motor coupled to a low inertia centrifugal rotor/impeller. The process of acceleration and deceleration of the rotor involves moving from frequency A, amplitude A to frequency B, amplitude B in an optimal linear fashion using the so-called Bresenham algorithm. This is coupled with a tuned increase of the amplitude during the acceleration process which will produce the acceleration using minimum current allowing the use of smaller power supplies. During deceleration the process is accomplished in reverse fashion using a tuned decrease of the amplitude coupled with a special shunt circuit to prevent power supply voltage changes. These changes in amplitude overlay a current feedback mechanism used to prevent loss of synchronization of the motor by changing amplitude. Speed changes can also be timed so as to prevent desynchronization.

An adaptor for coupling rapid exchange-type catheters to a catheter re-sterilizing system. Specifically, the adaptor fluidly couples the guidewire lumen of a rapid exchange-type catheter to a source of sterilant so that the sterilant may be positively directed to and through the guidewire lumen, thereby allowing the catheter to be properly 'reprocessed' or sterilized for reuse.

Catheter sterilizing cassette

A system for reprocessing and sterilizing a previously used catheter having at least one lumen is disclosed. The catheter is provided with a housing and enclosed within the housing. Heated sterilant is provided to the housing and the catheter. The lumen is tested during the reprocessing and sterilizing cycle for blockages and integrity. If the catheter is of a type having a balloon tip, the balloon is also tested for integrity by inflating and deflating it a plurality of times. The housing is pressurized to a level above the ambient pressure and maintained at such pressure whereby the sterility of the catheter is maintained for up to one week. Further disclosed is an apparatus for selectively coupling used catheters to a source of sterilant. The apparatus includes a housing having a tray for holding the catheter in place during reprocessing, a door for enclosing and locking the catheter within the housing, and a plurality of valves for coupling the housing to a source of sterilant. In addition, the apparatus includes a cap for maintaining the sterility of the catheter during storage.
