Filed:

Jun 22, 2009

Appl. No.:

12/488804

Inventors:

Michael B. Jones - Excelsior MN, US
Gregory Wayne Parkhurst - Brooklyn Park MN, US
Timothy Woodward Zeigler - Independence MN, US

Assignee:

Wagner Spray Tech Corporation - Plymouth MN

International Classification:

F04B 49/06
F04B 35/04

US Classification:

417 4411, 417 441, 417417

Abstract:

A fluid delivery system includes a pump operably coupleable to a source of fluid. A reciprocating electromagnetic actuator is coupled to the pump and has a coil that when energized causes the actuator to drive the pump. Coil current sensing circuitry is configured to provide an indication of current flowing in the coil. A controller is coupled to the coil current sensing circuitry and is configured to calculate a coil drive parameter based upon a plurality of coil current indications from the coil current sensing circuitry. Coil drive circuitry is coupled to the controller and is configured to supply current to the coil based on the coil drive parameter.

International Classification:

G05D009/00

US Classification:

700281000

Abstract:

The system is designed to provide PC based comprehensive fluid management for automotive lubrication that is easy to install, operate and troubleshoot. The system utilizes facility's current business PC and is comprised of PC software, wireless PC transceiver, linked wireless repeater, standard wireless repeater, wireless electronic meter, wireless tank level monitor and pulse charger all in quantities as required for a given service facility. The PC software communicates directly with the meters via wireless communication modules (e.g. PC transceiver and repeaters) to set desired operational defaults, to control security authorization (if desired), to receive all dispense transactions (tied to work order or repair order if desired) and to receive rechargeable battery levels.

Appl. No.:

10/530692

Inventors:

Mark King - NEW RICHMOND WI, US
Eugene Thury - St Paul MN, US
Gregory Parkhurst - Brooklyn Park MN, US
Michael Marshik - Circle Pines MN, US

International Classification:

B67D 5/16

US Classification:

222071000

Abstract:

The invention replaces mechanical actuation of the valve () in lubricant dispense meters () to provide a software driven method of controlling the dispense of fluids. The design utilizes either a pressure sensitive membrane switch or a multi-position membrane switch () in conjunction with either a multistage solenoid actuated valve, a proportional solenoid actuated valve or an on/off solenoid actuated valve () to provide operator or programmed control of lubricant dispense frequency and flow rate via the meter's microprocessor.

James Leo Campbell - Plymouth MN, US

Assignee:

Wagner Spray Tech Corporation - Plymouth MN

International Classification:

B67D 7/56

US Classification:

239 74

Abstract:

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.

International Classification:

G09B 23/28

US Classification:

434265

Abstract:

Disclosed are methodologies, a system and components thereof and associated computer programs for providing training/testing of one or more users performing treatment of Sudden Cardiac Arrest(SCA) victims. The system provides computer controlled interactive instruction and testing methodologies that enable one or more users to be trained and/or tested using a plurality of mannequins including circuitry and hardware that enable each users compressions to analyzed for rate, depth and recoil to ensure that each user is performing the chest compressions properly. The data collected for determining rate, depth and recoil are collected via mannequin-specific hardware and electronics that utilize a plurality of magnets provided in proximity to a Hall Effect sensor. Data is collected at each mannequin and transmitted to at least one computer processing unit operating to receive, collect, analyze and display the data as well as store data for subsequent use in individualized training and certification of users.
