摘要:
A telemetry system having: a pipe; a SCADA box acoustically coupled to the pipe; and a gauge inserted in the pipe, the gauge comprising: an acoustic wave generator; a coupler mechanically connected to the acoustic wave generator, wherein the coupler is engageable and disengageable with the pipe, wherein the coupler defines an acoustic transmission path between the acoustic wave generator and the pipe when engaged with the pipe; and a signal controller in communication with the acoustic wave generator. A method for communicating information in a wellbore from a downhole location to the surface, the method having the following steps: running a downhole gauge into a pipe within the wellbore, wherein the downhole gauge comprise an acoustic wave generator; setting the downhole gauge in the pipe; and communicating an acoustic signal between the downhole gauge and the pipe.

A method is used for editing a data element stored in a static memory device comprising a plurality of storage units. The method includes a step of copying a content of one of the storage units to a dynamic memory device, wherein the content comprises the data element. The method further includes editing the data element while the data element is stored in the dynamic memory. The method also includes erasing said one of the storage units, and writing the content, including the data element that has been edited, into one of the storage units.

A method is disclosed for cooling an alcoholic cocktail, consisting of the combining liquid nitrogen with the cocktail. The method is based on the high differential temperature between the liquid nitrogen and the cocktail, which provides for quick cooling and the capability of cooling the cocktail to its freezing point. The cooling process is enhanced by adding agitation to the mixture of the liquid nitrogen and the cocktail.

A multi-position sleeping structure includes a sheet material envelope having an opening into a cavity defined therein. An inflatable mattress is received and substantially enclosed within the cavity of the sheet material envelope. A cover portion which, in conjunction with a top surface of the envelope, defines a sleeping area in which a person can lie and be supported by the mattress. The mattress has a plurality of transversely extending hinges that separate the mattress into a first portion, a second portion, and a third portion. The hinges allow the mattress to be moved between at least a substantially flat sleeping position and a seating position. The sheet material envelope has a retaining pouch on a bottom side thereof that is positioned to receive the first portion of the mattress when in the seating position so as to retain the mattress in the seating position.

An online system and service that enables charities to receive and encourage donations through donors selling items, such as goods or services, in exchange for a charitable receipt from the charity. The system enables a seller to post an item for sale and for buyers to buy the item for sale at fair market value (FMV). The seller can designate one or more charities to receive all or a portion of the monetary proceeds from the sale. Through a filtering system the items are searchable by a number of criteria, including: charity, price, seller, recency of posting, etc.

A method and system for organizing referrals from at least one referrer to at least one referee for the purchase of products sold by merchants. The present invention further provides that referrers are compensated when a referee buys a specific product from a specific merchant that was referred to the referee by the referrer. Referrers and merchants, and optionally referees, are able to register with an online site to create a unique profile. For merchants, the unique profile will enable merchants to track products that are referable. For referrers, the unique profile will enable them to track which products they have referred to one or more referees.
