| 20110192285 | PSA Filter - The PSA Filter is a non-electronic air filter utilized in the interior or exterior of any device which uses air movement as a means of ventilation or circulation including, but not limited to a computer, printer or any other type of electronic or non-electronic devices. This invention consists of a base substrate which is covered with a PSA (pressure sensitive adhesive); such that the PSA material applied to the substrate is the active filtering element, this PSA coated substrate is inserted into or on a device for the purpose of trapping dirt, dust, pollen, fibers, and any additional types of air borne contaminants, that may inadvertently enter from the outside environment through factory installed vents, or that may be created inside of the device from its normal operations, thus said contaminants become trapped onto the PSA filter surface through air-circulation. | 08-11-2011 |
| 20120073443 | UNITARY SORBENT CANISTER WITH THIN END WALL - A sorbent container includes a permeable plastic container, a permeable membrane, and a sorbent. The permeable plastic container includes a sidewall and an endwall, the sidewall defining an opening opposite the endwall. The permeable membrane is fused to the sidewall to cover the opening. A fused junction is formed between the sidewall and the permeable membrane. The sorbent is disposed within the plastic container. | 03-29-2012 |
| 20130298774 | CONFORMAL SPLIT PLANAR FLOW AIR PURIFYING FILTER - A conformal filter is disclosed having a plurality of sorbent beds oriented perpendicular to an inner side surface of the filter which conforms to an adjacent surface, such as a wearer's face when attached to a respirator. The inner side of the filter may approximate the curved shape of an interfacing surface. Because the sorbent beds are oriented perpendicular to the inner side surface, a conformal configuration can be achieved without bending the sorbent beds and while keeping constant bed residence time throughout the entire cross-sectional area of the air flow, thus enforcing even air distribution. Reduced bed depth is also achieved through this configuration which consequently reduces the overall pressure drop through the filter. Other embodiments are described and claimed. | 11-14-2013 |
| 20140060332 | Dehumidifier with a Humidity Display Device - A dehumidifier with a humidity display device has a hook body, a housing, a display unit, an indication unit, and a recovery unit. The display unit is light-transmissive and is mounted on the housing. The indication unit is mounted on the hook body and has a humidity indicator and a fixing portion. The humidity indicator is mounted on the indication unit and is displayed through the display unit. The fixing portion is mounted on the indication unit. The recovery unit is mounted in the housing and is connected between the housing and the fixing portion. | 03-06-2014 |
| 20150040765 | FILTER FOR HUMIDITY CONTROL, TYPICALLY FOR CONTROL OF HUMIDITY IN A BULK LIQUID TANK - A filter is includes a housing and at least first and second adsorbent materials within the housing. The second adsorbent material has different characteristic from the first adsorbent material and is in series with the first adsorbent material. When assembled, a labyrinth arrangement is located between a first port in the housing and the first adsorbent material such that gas travels between the first port and the first adsorbent material by passing through the labyrinth arrangement. A filtration system and methods for humidity control of a liquid tank head space uses a filter, including first and second adsorbent and a diffusion channel or labyrinth arrangement | 02-12-2015 |
| 20160022951 | Ultra Rapid Cycle Portable Oxygen Concentrator - Lightweight, portable oxygen concentrators that operate using an ultra rapid, sub one second, adsorption cycle based on advanced molecular sieve materials are disclosed. The amount of sieve material utilized is a fraction of that used in conventional portable devices. This dramatically reduces the volume, weight, and cost of the device. Innovations in valve configuration, moisture control, case and battery design, and replaceable sieve module are described. Patients with breathing disorders and others requiring medical oxygen are provided with a long lasting, low cost alternative to existing portable oxygen supply devices. | 01-28-2016 |
| 20160074802 | Portable Dry Scrubber - A portable dry scrubber comprises a gas flow control module comprising a gas receiving unit that receives inflow of gas from surrounding atmosphere or from a gas source, a gas processing module that removes hazardous matter from the gas flowed in through the gas receiving unit and a connection module that connects the gas flow control module detachably to the gas processing module. The connection module comprises quick coupling device that establishes and disassembles a gas flow passage between the gas flow control module and the gas processing module. Example of the quick coupling device is a quick release vacuum flange that engages with a connecting flange of the gas flow control module. | 03-17-2016 |
| 20160375397 | DEHUMIDIFIER - A dehumidifier is revealed. A moisture-absorbing package comprises a pouch made of a fabric material having good breathability and hygroscopic substances filled in the pouch. A humidity-indicating unit made of a humidity sensing agent is mounted on an outer surface of the pouch, whereby upon saturation of water vapor as absorbed by the hygroscopic substances in the pouch, the humidity-indicating unit changes the color for indicating the timing of regenerating the hygroscopic substances. When the moisture-absorbing package is saturated with moisture, it is put in a box, and the box is put at an air outlet of a blowing device. The air blown from a blower of the blowing device is heated by an electric heating element and blown to the box for drying the moisture-absorbing package in the box to regenerate it. Then, the moisture-absorbing package removed from the box is put in different space to absorb moisture independently. | 12-29-2016 |
