Abstract:
A method for temporal registration of a first sequence of images and a second sequence of second images is described. The method comprises the following steps for: a) comparing the first parts of signatures of first images with corresponding parts of signatures of second images, b) temporally registering each first image with one of the second images according to the result of the comparison, c) calculating for each first image a value of quality representative of the quality of its registration, d) defining, for each first image for which the quality value is less than a threshold, a first sub-sequence from the first sequence and a second sub-sequence from the second sequence, e) comparing, for each first sub-sequence, second parts of signatures of first images of the first sub-sequence with corresponding parts of signatures of second images of the second corresponding sub-sequence, and b) temporally registering each first image of the first sub-sequence with one of the second images of the second sub-sequence according to the result of the comparison.

Abstract:
A method for making heated plane of a cooler obtain better flatness and roughness includes a grinder with a grinding plate and a fixture. Then, the cooler is arranged onto the fixture. Next, the abrasive is injected into the gap between the grinding plate and the heated plane, making the fixture press and clamp the cooler in a way, such that the heated plane of the cooler contacts the abrasive closely. Finally, the grinding plate is rotated to make at least one grinding process to the heated plane, making the heated plane obtain a surface with better roughness and flatness, further enhancing the contact tightness between the heated plane and a heating element, and therefore promoting the thermally conductive efficiency between the cooler and the heating element.
Abstract:
A method for producing a condenser for a thermal power plant is provided. First, the production method includes fitting a condenser tube in a carrier for a condenser tube bundle of the condenser. Then, the fitted condenser tube is coated with a hydrophobic coating. Coating the fitted condenser tube includes positioning a spray mechanism on the carrier, spraying on the hydrophobic coating using a spray mechanism, and moving the spray mechanism during spraying at a uniform rate. In another aspect, a device is provided. Also, a condenser is provided in an aspect.
Abstract:
A non-stick coating, which inhibits frozen moisture accumulation, is applied to the exterior exposed portions of a refrigerant/air heat exchanger, which heat exchanger is comprised of a capillary tube/plate means/design, which plate has an exterior surface that is comprised of at least one of raised dots, ridges, trenches, and a flat surface, which means/design facilitates the shedding of frozen moisture and maximizes heat exchanger surface area exposure to the air; for use in conjunction with an air source heat pump system, an evaporative cooling system or a chiller, or as a supplement to a water-source heat pump system or to a direct expansion heat pump system; and for use with any other refrigerant-based heating system or cooling system.
Abstract:
A thermoplastic polymer film is directly extruded onto the heated surface of a metal condensing heat exchanger. Any thermoplastic polymer capable of being adhered to the metal surface of the condensing heat exchanger can be utilized. Preferably, the thermoplastic polymer is a polyester, a polyolefin with an added maleate or tackifier to ensure adhesion, polyetherimide, polyethersulfone, polysufone or polyimide. The thermoplastic film must be resistant to the conditions of the condensing heat exchanger, such as the high temperature flue vent gases and the acidic condensate formed from condensation.
