Abstract: Aspects of the present invention relate to a tube for conveying a fluid. the tube comprising: a first passage: a second passage comprising a pressure sensor connection point through a wall of the second passage: and a valve configured to be in an open condition when a fluid flow through the tube in is a first direction and configured to be in a closed condition when the fluid flow through the tube is in a second direction, opposite to the first direction. wherein the pressure sensor connection point is upstream of the valve. when the fluid flow is in the first direction, and downstream of the valve. when the fluid flow is in the second direction: wherein. when the valve is in the open condition fluid can be conveyed via the first passage. and when the valve is in the closed condition fluid cannot be conveyed via the first passage.

Abstract: A patient warming system includes a control unit coupled to one or more warming devices. The control unit may control application of power to the heating elements of the warming devices. The control unit may provide hardware and/or software approaches to monitor and detect an overtemperature situation and/or fault of a given warming device.

Abstract: A heating element includes an electrically insulating layer; resistive layer formed of a positive temperature coefficient material; and an electrically conductive layer disposed between the electrically insulating layer and the resistive layer and including a first bus and a second bus that is spaced apart from the first bus, the resistive layer electrically connecting the first bus and the second bus. The electrically insulating layer, the electrically conductive layer, and the resistive layer are stacked to form a lamination and the lamination having a thickness and a width and length extending orthogonal to the thickness. The lamination may have slits extending through the thickness thereof and along a portion of the length thereof. Terminals may be connected to the buses and arranged to provide a counter current flow pattern across the lamination. The lamination may be used in a warming device and in connection with a patient warming system.

Abstract: A method for recovering ammoniacal nitrogen, in the form of ammonium carbonate and/or ammonium bicarbonate, from an ammoniacal nitrogen-containing vapor that comprises introducing said vapor into at least one pressurizable ammonia scrubbing vessel containing water, simultaneously introducing a carbon dioxide-containing vapor into at least one pressurizable carbon dioxide scrubbing vessel containing water, and simultaneously pumping the solutions created in said scrubbers via hydrologic connections between said scrubbers to mix the solution to create an ammonium carbonate and/or ammonium bicarbonate containing mixture, all while maintaining independent and unmixed vapor streams throughout the entire process. The method further involves recovering ammonium carbonate and/or ammonium bicarbonate from the mixture for further use.

Abstract: An organic waste material processing system includes a waste material holding tank and a slurry-producing device configured to process organic waste material into a slurry. A waste processing section has at least one pressurizeable tank connected to the waste material holding tank receiving slurry therefrom. The pressurizeable tank includes a slurry temperature adjusting part and a first hydrocarbon capturing structure configured to capture hydrocarbon vapors produced by the slurry at a predetermined temperature. A hydrocarbon vapor processing section collects captured hydrocarbon vapors from the waste processing section such that an electric power producing apparatus generates electricity using collected hydrocarbon vapor and provides electric power to at least the pretreatment section and the waste processing section. A waste post-processing section is configured to receive processed slurry produce salable organic materials, nutrient enhanced media and recycled water.

Abstract: Some embodiments of the invention enable users to manage codes which may be redeemed for value. For example, some embodiments provide systems and methods for automatically identifying a code communicated to a user which is redeemable for value, and adding the code to an inventory maintained for the user. When the user later shops at a site which allows a code to be redeemed for value, some embodiments of the invention may automatically detect when the user has navigated to a page on the site which allows redemption of the code, and may make the user aware that the code may be redeemed on the page. If the user opts to redeem the code, the field on the page into which the code is to be input may be automatically identified, and the code may be automatically input into that field.

Abstract: Systems and methods are provided which enable a consumer to accept a promotional offer for a credit card-based reward program without having to supply a credit card number at the time of acceptance. For example, after acceptance, a credit card number associated with the consumer may be retrieved from an entity to which the consumer previously supplied it, such as a publisher (e.g., e-commerce website), and the retrieved number may then be used in relation to the reward program.
