Abstract: A system and method for treating wastewater using concentrated solar energy are described herein. The system includes a lens that is positioned either on or adjacent, or forms part of a façade of a building. A fluid passageway, through which the wastewater is circulated, is positioned either within or adjacent the lens. The lens is configured to direct solar energy onto the wastewater to treat the wastewater.

Abstract: A fuel heating apparatus capable of heating fluid by use of solar energy to provide water for daily life is provided. The fuel heating apparatus includes a water tank, a lifting part and a control part. The water tank is configured to form an accommodation formed therein to store fluid, has an inlet/an outlet which are formed through the water tank to receive and discharge fluid, respectively, and is formed using light passing material or thermal conductive material. The lifting part is vertically installed at facing sides of the window to lift the water tank such that the fluid is heated through sunlight or solar heat introduced through the window. The control part controls operations of the lifting part. The heated fluid provided to the water tank is used for daily life water.

Abstract: A solar collector (1) includes two panels (2, 3) of which at least one panel (2) can be designed as a solar module, wherein the panels (2, 3) are connected to each other and held spaced apart from each other by webs (5) that are distributed over the surface of the solar collector (1). The webs (5) between the panels (2, 3) of the solar collector (1) are arranged in such a manner that the interior space (4) is divided to form a flow path, which can be achieved as a result of the fact that the webs (5) start alternately from one edge (9, 10) of the solar collector (1) and are spaced from the opposite edge (10, 9). The webs (5) are strips that are connected via plastic strands (12) to the inner faces of the panels (2 and 3).

Abstract: A matched glass-to-metal connecting device for use in a vacuum tube collector for a solar energy collecting apparatus is made of a glass envelope and a metal sleeve directly bonded to the glass envelope. The glass envelope is made of a glass having a composition, in percent by weight on the basis of oxide content, consisting essentially of B2O3, 19; Al2O3, 8; Na2O, 2; K2O2, 3; BaO, 3; LiF, 1; and balance of SiO2 and the metal sleeve consists of metal material number 1.3981 of DIN 17745. The glass envelope has a thermal expansion coefficient that deviates from the metal part's thermal expansion coefficient by no more than 4% in the temperature range from 25° C. to 350° C.

Abstract: In an electronic blood pressure measurement device which is arranged to extract pulse waves from the measured cuff pressure, a pulse wave pattern is generated from the pulse wave amplitude and pulse wave interval data and this pulse wave pattern is compared with reference patterns to classify the pattern in order to accurately obtain biological information other than the blood pressure. Blood pressure amplitudes PA(i) are computed from the measured cuff pressures C(i) and a pulse wave pattern is generated (35) on the basis of this pulse wave amplitude data and this pulse wave pattern is classified into a plurality of reference patterns (37) according to reference patterns or reference values (36). Here, the reference patterns or reference values are set as hemodynamic references based on dynamic characteristics of the blood vessel or cardiac output characteristics.
