Abstract: The present invention provides a laser spot light with improved radiating structure which includes a cylindrical shell, a mounting board fixed within the cylindrical shell, at least one laser head, an inner radiator made from heat-conductive metal and configured for supporting the at least one laser head and fixed on the mounting board, and an outer radiator made from heat-conductive metal and fixed to the side wall of the cylindrical shell with a part of the outer radiator passing across the cylindrical shell and touching with the inner radiator. Therefore an inner heat can be conducted to the outside of the cylindrical shell, and an operation temperature of the laser head can be maintained in a normal range.

Abstract: The present invention provide a constant current and temperature compensation control device for outdoor spotlights used on laser stages which includes a single chip microcomputer, a triode or an field effect transistor, a laser LED light, a heating piece and a driving triode used for driving the heating piece. The benefits of the present invention include protecting the laser light from damage caused by power surge which results in no light or weakened light intensity, saving the cost of a specialized current limiting chip, making the green laser module work normally in extremely cold outdoor environment thus being more favorable to apply this device to mood creating lights of Christmastime.

Abstract: An apparatus for disassembling an electronic component from a circuit board includes a base, a controller, a positioning assembly, and a heating and suction assembly. The controller is fixed to the base. The positioning assembly is arranged on the base and coupled to the controller. The positioning assembly is configured to be controlled by the controller to position the circuit board at a first predetermined position. The heating and suction assembly is movably arranged on the base and coupled to the controller. The heating and suction assembly is moved to a second predetermined position to heat the electronic component and moved to a third predetermined position to attract and hold the heated electronic component by suction, whereby the electronic component is disassembled from the circuit board.

Abstract: A microcuvette is provided, including a body having a slit inside. The slit connects to an entry slit and an exit slit, and the entry slit and the exit slit are on the opposite side of the body. The microcuvette is characterized in that the slit includes a drainage slit, an optical measuring slit, and a protecting slit. The drainage slit directly connects to the entry slit, the optical measuring slit, and the protecting slit. The protecting slit at least partially surrounds the optical measuring slit and connects to the exit slit. The drainage slit has an average width not larger than the optical measuring slit, and the protecting slit has a width larger than the optical measuring slit. The microcuvette of the present invention is convenient to use, disposable, and can reduce factors affecting measurement results.

Abstract: A new class of chemiluminescent acridinium or benzacridinium compounds is disclosed by virtue of forming an intramolecular energy transfer conjugate (ETC) between the acridinium or benzacridinium compound and a luminophore. A method of extending the emission wavelengths of acridinium or benzacridinium esters in order to further reduce or eliminate the emission spectral overlap between the parent polysubstituted aryl Acridinium Esters (DMAE) and Benzacridinium Esters (LEAE) is disclosed. The ETC's retain the unique desired properties of acridinium or benzacridinium compounds including complete light emission in very short period of time, monophasic emission spectrum, simplicity of triggering mechanism, ability of labeling the biological molecules of interest to form a tracer, and good stability. Additionally, the range of the emission spectrum of an acridinium or benzacridinium compound can now be shifted at will and at longer leap through the choice of a luminophore as the integral part of an ETC molecule.

Abstract: An assay method incorporating at least two different chemiluminescent compounds for detection and/or quantitation of at least two substances in a test sample is described. The synthesis of chemiluminescent reagents or conjugates for use in such methods as well as kits incorporating such reagents are also disclosed. The assays have particular application in the field of clinical diagnostics.
