20090095160 | ELECTROSTATICALLY CHARGED ENGINE INTAKE FILTER MEDIA - A filter for internal combustion engine air intake comprised of a synthetic fiber media uniquely enhanced with an electrostatic charge. The media described in this application is a low restriction synthetic fiber media enhanced with an electrostatic charge applied to the media fibers to greatly improve efficiency and dust holding capacity. This charge is so effective that unlike other mechanical filters the initial efficiency of this media is as high, or higher than its efficiency after use. The applied charge will either attract particles of an opposite charge that might otherwise pass through the media or in cases of particles with similar charges an induced dipole is formed to attract those particles. The claims of this patent will not be for the method of enhancing this media but for its use and configuration for use in engine intake air filtration. | 04-16-2009 |
20120144791 | CAPTIVE TOOLEES FASTENER FOR SECURING AN ENGINE INTAKE AIR FILTER AND CLAMP ASSEMBLY FOR AIR FILTER HOUSING - The invention has a captive tooless fastener for securing the engine intake air filter. The tooless fastener comprises shaft and associated bodies. The body has two arms oriented about 180 degrees apart. The shaft is threaded through a sealing washer and an aperture in a closed end cap of the air filter. The shaft is expanded so it cannot be removed from the end cap. The body's threaded inner diameter mates with a threaded portion of a central shaft in an air filter housing. The body's arms are rotated to screw the fastener and the shaft of the housing together. When tightened, the sealing washer closes the aperture. To remove the air filter, the fastener is unscrewed from the shaft of the housing and in the shaft floats in the aperture. A person in the field can remove the air filter by inserting fingers under the arms and pulling. | 06-14-2012 |
20130256203 | NET ASSEMBLY FOR POOL SKIMMER - A removable skimmer net assembly that securely sits within the mouth of any conventional pool skimmer to passively collect floating debris from the surface of the water. The skimmer net assembly includes a removable pool net and a skimmer mount having a telescoping column and a T-shaped net orientation connector. The telescoping column secures the mount within the mouth of the pool skimmer in either a vertical or horizontal orientation. The net orientation connector allows the removable net to be properly positioned within the pool regardless of the orientation of the telescoping column or the style of skimmer. The removable pool net is connected to the skimmer mount by a dove-tail joint that allows the net to be easily disconnected from the mount for cleaning or when the pool is in use. | 10-03-2013 |

20080238650 | CONFIGURABLE NETWORKED USER INTERFACE AND SWITCH PACK - A printed circuit board (PCB) has a plurality of switch interfaces on its top surface. Each interface is an array of sensors, such as proximity sensors, hall-effect sensors, or a series of inductor coils. The sensors in each array are closely mounted and are all the same for a given PCB. Each array may or may not mount a non-contacting switch selected from a plurality of different types of switches, such as a single push button switch, dual push button switch, a toggle switch, a 3-position rocker switch, a rotary switch, or other type switch. Each switch mounted on the PCB includes one or more indicators for sensing by the sensors or coils, with feedback to determine what type of switch is mounted in each position.
