  • Patent number: 9287437
    Abstract: A method for monitoring the process of fabricating solar cells generally comprises performing a reaction process in a chamber for a solar cell substructure, wherein the chamber includes a reaction solution that includes at least one chemical component. A concentration value is detected for the chemical component during the reaction process, via a detection assembly that is coupled to the chamber. The method further includes determining whether the detected concentration value is at a predefined threshold concentration level or within a predefined concentration range for the chemical component, via a control assembly that is coupled to the detection assembly. The concentration of the chemical component within the reaction solution is modified, during the reaction process, when the detected concentration value is different from the predefined threshold concentration level or different from the predefined concentration range.

  • Patent number: 7806733
    Abstract: A SATA data connector is provided with a power supply circuit. The SATA data connector comprises a male data connector and a female data connector. The male and female data connectors includes a signal interface having seven data connection pins. The male and female data connection pins each consist of four data pins, a power supplying pin or power receiving pin, and two ground pins, wherein the power supplying pin connects with a power line of a circuit board. Mating the female data connector to the male data connector causes an operating power to be supplied from the power line of the circuit board to an applied device connected to the female data connector such that the SATA data connector can work without an external SATA power cable.

  • Patent number: 7641518
    Abstract: A modified standard SATA data connector is provided with a power supply circuit. The connector includes male and female data connectors. A male signal interface has seven male data connection pins, consisting of four data, a power supply, and two ground pins, the power supply pin replacing one of three original ground pins and connecting with a power line of a circuit board. A corresponding female signal interface has seven female data connection pins consisting of four data, a power receiving, and two ground pins. While the female and male data connectors are engaged, power can be supplied from the power line of the circuit board to an applied device connected with the female data connector via the power supplying and receiving pins. Thus, the SATA data connector can work without an external SATA power cable, and the volume of the cable can be reduced.
