High Pass Filter Applications





high pass filter applications






    applications
  • (application) the act of bringing something to bear; using it for a particular purpose; "he advocated the application of statistics to the problem"; "a novel application of electronics to medical diagnosis"

  • A formal request to an authority for something

  • (application) a program that gives a computer instructions that provide the user with tools to accomplish a task; "he has tried several different word processing applications"

  • The action or process of making such a request

  • The action of putting something into operation

  • (application) a verbal or written request for assistance or employment or admission to a school; "December 31 is the deadline for applications"





    pass filter
  • A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit).





    high
  • A high-frequency sound or musical note

  • at a great altitude; "he climbed high on the ladder"

  • A notably happy or successful moment

  • a lofty level or position or degree; "summer temperatures reached an all-time high"

  • A high point, level, or figure

  • greater than normal in degree or intensity or amount; "a high temperature"; "a high price"; "the high point of his career"; "high risks"; "has high hopes"; "the river is high"; "he has a high opinion of himself"











Kodak Infared HIE




Kodak Infared HIE





Black-and-white infrared negative films are sensitive to wavelengths in the 700 to 900 nm near infrared spectrum, and most also have a sensitivity to blue light wavelengths. The notable halation effect or glow often seen in the highlights of infrared photographs is an artifact of Kodak High Speed Infrared (HIE) black-and-white negative film and not an artifact of infrared light. The glow or blooming is caused by the absence of an anti-halation layer on the back side of Kodak HIE film, this results in a scattering or blooming around the highlights that would usually be absorbed by the anti-halation layer in conventional films.
Frank Lloyd Wright's Rudin House: panchromatic film on the left, infrared on the right

The majority of black-and-white infrared art, landscape, and wedding photography is done using orange (15 or 21), red (23, 25, or 29) or visually opaque (72) filters over the lens to block the blue visible light from the exposure. The intent of filters in black-and-white infrared photography is to block blue wavelengths and allow infrared to pass through. Without filters, infrared negative films look much like conventional negative films because the blue sensitivity lowers the contrast and effectively counteracts the infrared look of the film. Some photographers use orange or red filters to allow slight amounts of blue wavelengths to reach the film, and thus lower the contrast. Very dark-red (29) filters block out almost all blue, and visually opaque (70, 89b, 87c, 72) filters block out all blue and also visible-red wavelengths, resulting in a more pure-infrared photo that usually looks more contrasty.

Certain infrared-sensitive films like Kodak HIE must only be loaded and unloaded in total darkness. Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film.

As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved."[6] At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.

Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the market with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.

20110708 Great Cluster in Hercules (M13)





I don't do a lot of Clusters, because they are so difficult to process. The high dynamic range and small color saturation variations have alluded me to date. This is only a very short experiment (15min of LRGB data).

The test which I referred to: I wrote a Filter wheel / Camera interface which I can pass parameters to upon start, and it operates the exposures and filter wheel so it can work unattended. It's the first part of a program I'm writing to be an All-in-1 acquisition software. So far so good - the data pulled from the camera was solid, the filter wheel operated flawlessly, and the metadata was recorded in the FITS files as intended. Next step is to incorporate this scripting into a windows application with GUI and combine it with real-time image monitoring/comparison with zoom/pan functionality.

Liquid Bag Filter





liquid bag filter






    bag filter
  • A type of filter that collects lint from the drying cycle. or A filter that was used in powder filtration systems. The bag filter was coated either inside or outside with filter powder which trapped the soils. The bag was held in place by a frame and when full or clogged the frame was removed.

  • a pressure filter where fabric bags are installed inside a cylindrical housing (pressure vessel) and the filtered liquid is pumped through the bag walls. Liquid flow is from the inside to the outside of the bag - dirt is trapped inside the bag.

  • textile or sintered polymer filters used to remove dust and fume particles from gas streams. Used also on liquid waste to provide a final polish or remove floc particles





    liquid
  • existing as or having characteristics of a liquid; especially tending to flow; "water and milk and blood are liquid substances"

  • a substance that is liquid at room temperature and pressure

  • the state in which a substance exhibits a characteristic readiness to flow with little or no tendency to disperse and relatively high incompressibility

  • Having a consistency like that of water or oil, i.e., flowing freely but of constant volume

  • Denoting a substance normally a gas that has been liquefied by cold or pressure

  • Having the clear shimmer of water











liquid bag filter - AeroPress Coffee

AeroPress Coffee and Espresso Maker with zippered nylon tote bag and an Extra 350 Micro Filters (700 Total)



The AeroPress is an entirely new way to make coffee, American style or Espresso style for use in lattes, cappucinos and other espresso based drinks. AeroPress brews simply delicious coffee, 1-4 cups per pressing. Ideal water temperature and faster brewing yields rich flavor with lower acidity and without bitterness. Other brewing processes use near boiling water and long exposure to coffee grounds. Quickly brew a variety of coffee drinks including an Americano or an espresso-style shot for use in lattes or cappuccinos. Its total-immersion system permits extraction at a moderate temperature and a short brew time. Water and grounds are mixed together for 10 seconds, then gentle air pressure pushes the mix through a micro-filter in just 20 seconds, which avoids the bitterness of long processes such as drip brewing. The air pressure also gently squeezes the last goodness from the grounds, further enriching the flavor. The total brewing time of only 30 seconds results in an exceptionally smooth brew.

The filter bags are dried in this box after they are taken out of the MAP precipitation reactor. The reactor and the box are installed in the office building within the project SANIRESCH.

Crush n Run Surly Setup





This is my setup for the 50 mile Crush n Run race.

I'm not 100% sure if I'll use the mountain feed bag on my handlebars. I generally like it but my knees rub it when I'm standing and climbing.

Also not positive if 3 bottles will be enough liquid.
