A piece of camping furniture with a flexible structure allowing the user to easily assemble, disassemble, and carry both a cot and a chair with a minimum amount of weight. The piece of furniture consists of cloth, longitudinal poles, and moveable cross pieces that can be configured as both a cot (for sleeping) and a chair (for sitting) depending on the spacing of the cross pieces and the angulation of the longitudinal poles.

A membrane cartridge is manufactured by repeatedly folding and joining two strips of membrane to form a cross-pleated cartridge with a stack of openings or fluid passageways configured in an alternating cross-flow arrangement. The cartridge can be modified for other flow configurations including co-flow and counter-flow arrangements. Methods for manufacturing such cross-pleated membrane cartridges, as well as apparatus used in the manufacturing process are described. Cross-pleated membrane cartridges comprising water-permeable membranes can be used in a variety of applications, including in heat and water vapor exchangers. In particular they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams being directed into and out of buildings.

A method determines a number of unique values in a sample of a list of values and estimates a number of the unique values for an unsampled portion of the list of values. The method estimates a number of the unique values in the list by adding the number of unique values in the sample to the number of the unique values in the unsampled portion.

An enhanced system and method for handling, matching and executing a diverse group of limit-priced orders in an electronic options environment is disclosed. Most of the order types disclosed are automatically repriced and reposted as the NBBO changes to increase their execution opportunities. Market maker entitlements are integrated with the order processing, so that the market maker is guaranteed an allocation of the trade if the market maker is at the NBBO when an order priced at or better than the NBBO is received. Once posted to the order book, the displayed price of an order may be eligible for preferential execution in a market maker entitlement process, regardless of whether the displayed price is original or has been automatically repriced.
