Abstract

A concentric split flow filter may be configured to remove odor and/or bacteria from pumped air used to collect urine and fecal waste products. For instance, filter may be designed to effectively fill the volume that was previously considered wasted surrounding the transport tube of a waste management system. The concentric split flow filter may be configured to split the air flow, with substantially half of the air flow to be treated traveling through a first bed of filter media and substantially the other half of the air flow to be treated traveling through the second bed of filter media. This split flow design reduces the air velocity by 50%. In this way, the pressure drop of filter may be reduced by as much as a factor of 4 as compare to the conventional design.

Abstract

A water recovery system includes a sorbing bed, a desorbing bed, a heat pump and a controller. The sorbing bed receives a first fluid stream and absorbs and/or adsorbs water from the first fluid stream. The desorbing bed is aligned with and thermally connected to the sorbing bed, and receives a second fluid stream and desorbs water to the second fluid stream. The heat pump is positioned between the sorbing bed and the desorbing bed and transfers heat from the sorbing bed to the desorbing bed. The controller distributes power to the heat pump to maintain an area near the outlet of the desorbing bed at a temperature greater than an area of the sorbing bed aligned with the area near the outlet of the desorbing bed. A method for recovering water from a fluid stream includes directing fluid streams through the described water recovery system.

Abstract

An arrangement for controlling remote devices includes two networked computers. The first computer displays a first file that is stored on the first computer and the second computer displays a second file that is stored on the second computer. The computers send non-graphical commands back and forth to page up or down, zoom, or pan the displayed files in response to commands input into either of the computers. This allows an operator at either computer to view output corresponding to the commands input into the other computer. The first and second files are essentially the same and are retained on the respective computers, so there is no need to send relatively large graphical data packets over the network. Use of relatively small non-graphical data packets reduces the network bandwidth used.
