A cable retraction system, useful at least in vital signs monitoring systems, rolls sensors cables and tubes on rotary spring spools, inside a protective enclosure, for storage. The cables and tubes along with the sensors can easily be pulled out for use and then retracted back into the enclosure as required. This eliminates tangled cables and tubes and provides protection for the sensors by not being on dangling long cables when not in use.

Disclosed is an apparatus having: a pressure chamber and a gas-producing microorganism within the chamber. The pressure chamber is capable of maintaining a gas pressure of at least 0.5 psi above atmospheric pressure.

Bacteria-based gas generator

A device having: a chamber having a gas inlet, a gas vent, and a liquid vent; and a float and a weight coupled to the chamber. The float has a lower density than the chamber. The weight has a higher density than the chamber. The aggregate density of the chamber, the float, and the weight is greater than the density of the chamber. The gas inlet, the gas vent, the liquid vent, the float, and the weight are positioned on the chamber such that: when the chamber is filled with and submerged in a liquid in which the chamber is neutrally-buoyant, the chamber is oriented to place the gas vent below the gas inlet; and when a gas is introduced through the gas inlet into the chamber that is filled with the liquid, the chamber pivots to raise the gas vent until a portion of the gas escapes from the chamber through only the gas vent.

Bouyancy control device

A method of: providing a mixture of fecal waste and a bacterium; incubating the mixture to produce a fatty acid enriched mixture; removing water from the fatty acid enriched mixture to produce a dried mixture; and pyrolyzing the dried mixture in an inert atmosphere to produce an alkane from the C-Cfatty acid. The bacterium is a type that produces a C-Cfatty acid in the presence of any microbes in the fecal waste.
