Abstract: A refraction method and a compound lens is disclosed for concentrating solar beam in a non-imaging manner for its heat to be harvested and utilized, for example, for generating electricity with thermo-electric or thermocouple circuit when its hot junction is heated. Solar beam (S1), which may be collected over a wide span of the sun's movement without need for tracking, is first refracted with a first positive refractory element which may preferably be an asperical biconvex lens (11). The exiting, i.e. second solar beam (S2), at a still convergent angle is then refracted by a second negative refractory element which may preferably be a biconcave lens (12). The exiting, i.e. third solar beam (S3), converges upon a third positive refractory element, preferably another aspherical biconvex lens (13), which concentrates the exiting solar beam (S4) onto the predetermined heat collection surface area (120). The sum of all the curvature surfaces of the compound lens times the indices of refraction is about zero such that the field of focus is flat. Preferably, the sum of refractive powers of the first and third aspherical biconvex lenses is substantially counter-balanced by the refractive power of the second biconcave lens placed thereinbetween said first and third lenses.

Abstract: A luminescence based water quality sensor system (10) comprises a dual sensor material (300) having at least one layer of two indicator sensor dyes that display two largely different decay times in a single hydrogel matrix, in which each indicator sensor dyes measures a specific analyte relating to water quality, a light source (100) which provides photon source to the dual sensor material (300), an excitation source (200) which includes a polarization controller (201) to modulate and polarize the light source (100), and a detector unit (400) having a spectral filter (401) to filter the emission wavelength before detecting by a photodetector (402). The changes of the analyte to be measured quenches the luminescence emission of a sensor dye by determining the decay time of a reference indicator by measurement of the phase shift of the detected emission signal at two different modulation frequencies for a real- time and simultaneous calculation of the concentration of at least two analytes to be measured.

Abstract: The invention provides a tunable filter (100) comprising a plurality of reflective layers (101, 102), a plurality of electrode layers (105,108), a plurality of insulation layers (112,114), a plurality of spacers (120, 121) and a plurality of actuator layers (106a,106b). The first cavity (floating cavity) (201) is defined by the gap between the reflective layers (101, 102) and the second cavity (202) is defined by the gap between two electrode layers (105, 108). The actuator layers (106a, 106b) play a major role for assisting in causing variation respective to the gap distance of the reflective layers (101, 102) therefore providing a variation of the resonant wavelength of the filter (100). This occurs when voltage is applied across the first cavity (201). In another embodiment, when voltage is applied across at least one of the second cavities, (202a, 202b) the tilting of electrode layers (105, 108) causes alteration of the gap of the second cavity (202a, 202b) therefore providing variation with respect to the incident angle. Such characteristics therefore provide wider tuning range. (Figure 1)

EACH OF THE TWO SIDES OF THE SILICON SUBSTRATE IS TEXTURED WITH A LASER SOURCE TO ROUGHEN ITS SURFACE BY FABRICATING NANOSCALE STRUCTURES THEREON. SURFACE TEXTURING MAY BE CONDUCTED ON BOTH SIDES OF A CRYSTALLINE SILICON WAFER BY FLIPPING OVER TO REPEAT OUR PROCESS ON THE OTHER SIDE SUCH THAT SUNLIGHT REFLECTIVITY IS MINIMIZED AND PHOTON TRAPPING IS MAXIMIZED. THE PROCESS MAY BE CONDUCTED IN ROOM TEMPERATURE AND VACUUM IN A DRY-ETCH PROCESSING ENVIRONMENT. THE SUBSTRATE MAY UNDERGO TRANSLATION IN THE X-Y AXES FOR CONTROL OF THE SUBSTRATE’S MOVEMENT TO ACHIEVE THE REQUISITE TEXTURING BY THE LASER BEAM OF A PULSE LASER OF ND-YAG SOURCE IN 533 NM AND 1024 NM WAVELENGTHS AT ≥ 75 JOULES/PULSE WITH TRANSLATION SPEED OF ≤ 0.5 MM/SECOND. OUR PROCESS IS SUITABLE FOR SOLAR CELLS THAT INCLUDES HETEROJUNCTION STRUCTURES, SPECIFICALLY, WITH INTRINSIC THIN LAYER (HIT) STRUCTURE AND PARTICULARLY ON CRYSTALLINE SILICON (C-SI) (P-TYPE) SUBSTRATE WHICH MAY INCLUDE EXPOSURE TO NANO-SECOND TO FEMTO-SECOND RANGE PULSED LASER ON DRY THIN FILM SOLAR CELL WAFER.

Abstract: The present invention relates to a parking management system and a method of identifying and allocating a parking space for a vehicle. One of the advantages of the present invention is that the passive sensing device in this present invention uses optical fiber technology in combination with simple water pipe construction that laid without a need to cut the tarmac on the surface of the parking lot during installation of inductive loop detectors. The elimination of active devices in the parking system of the present invention increases the cost effectiveness of deploying such system as compared to all the deployment using active sensing devices such as ultrasonic sensor, video imaging and inductive loop sensor.
