摘要： A system and method for recovery of CO2 includes an aqueous capture device having a capture solution. The aqueous capture device is arranged to receive gas and to capture components from the gas including at least CO2. An electrodialysis unit in operative connection with the capture device performs an electrodialysis operation on the capture solution including at least the CO2, wherein a CO2 rich process stream and a regenerated capture solution are generated from the capture solution including at least the CO2. The CO2 rich process stream is a pressurized process stream at a pressure which maintains the CO2 substantially within the CO2 rich process stream, while in the electrodialysis unit. In another alternative, at least the pH of the capture stream is controlled.

摘要： A rotational trough reflector solar-electricity generation device includes a trough reflector that rotates around a substantially vertical axis and includes a solid optical element having a linear parabolic convex surface that serves as a base for automatically positioning a mirror to focus sunlight onto a focal line, and a flat aperture surface that serves to support a strip-type photovoltaic (PV) receiver on the focal line. A tracking system rotates the trough reflector such that the trough reflector is aligned generally parallel to the incident sunlight (e.g., in a generally east-west direction at sunrise, turning to generally north-south at noon, and turning generally west-east at sunset). A disc-shaped support structure is used to distribute the reflector's weight over a larger area and to minimize the tracking system motor size. Multiple trough reflectors are mounted on the disc-shaped support to maximize power generation.

摘要： The presently described embodiments are directed to a calibration method and system for thin film thermistors that are locally heated with integrated thin film heaters. Initially, print head temperature is either measured or referenced. Then, transient thermistor resistances are measured and used to determine the thermistor resistance at a higher temperature. Notably, this calibration method is advantageously implemented as a step of an existing process without having to expose the print heads to operating temperatures. In some implementations of the presently described embodiments, trimming of the thermistors may be required once calibrated.

摘要： This invention provides a method and apparatus for substantially eliminating deposition on the edge of a wafer supported on a pedestal in a processing chamber. Process gas flow onto the wafer surface is inhibited from reaching the wafer edge and backside, by means of a shadow ring placed over the wafer without touching it. Deposition on the edge and backside of the wafer are therefore substantially eliminated. The shadow ring defines a cavity which circumscribes the wafer edge, into which purge gas is flowed. This purge gas flows out from the cavity through the gap between the shadow ring and the upper surface of the wafer. Alignment pins are placed on the wafer supporting surface of the pedestal. These pins have sloping surfaces and are arranged to guide the wafer to a centered position on the pedestal when the wafer is placed on the pedestal. These pins also serve to align the shadow ring to the pedestal and thence to the wafer. The shadow ring has a plurality of keyed formations which mate to the pins, and as the shadow ring and pedestal are brought together, the pins serve to align the shadow ring. This precise rotational alignment and centering of the shadow ring results in substantial elimination of edge deposition. The keyed formations have elliptical cross-sections to provide for radial movement of the pins with respect to the keyed formations due to thermal expansion.
