  • Patent number: 10080266
    Abstract: A plug-in multifunctional LED power system includes a power supply module, at least one output terminal, a switch module, a trigger conversion module, a compatible circuit module, and a replaceable control chip module. The trigger conversion module includes a first, second and third resistors connected in series from a high level output terminal to a ground. The switch module includes an N-type MOS transistor. The compatible circuit module is used for controlling on-off of the switching module by different control chip modules. The control chip module processes the input signal of the signal access unit and outputs a control signal for controlling the on/off of the switching unit so as to control the operating state of a LED lamp. The plug-in multi-functional LED power supply system can solve the increase of the production costs and the inconvenience for user installation caused by more existing power supply types and different models.

  • Publication number: 20180235262
    Abstract: The present invention relates to a preparation method of high-quality apple jam. The preparation method integrates crushing, pulping and steam enzyme deactivation, and immediately adopts ultra-fast cooling after pulping and enzyme deactivation. The ultra-fast cooling integrates vacuum cooling and chilled brine conduction cooling. The whole technological process features strict control over parameters, retention of the original color, luster, flavor and nutrients. The present invention includes the following procedures: quality control of raw materials, namely apples, combination of crushing, pulping and steam enzyme deactivation, ultra-fast cooling, filtration, separation, multi-effect low-temperature concentration, formulating, canning, sterilization and fast cooling. The preparation process of the present invention not only greatly reduces the enzymatic browning of the polyphenol oxidase, but also effectively avoids losses of its flavor and nutrients such as sugar, proteins, mineral substances and etc.

  • Publication number: 20140115360
    Abstract: The present invention relates to a method for reducing dynamic power consumption and an electronic device. The method includes: receiving a bus signal; when information about access to the slave device exists in the bus signal, inputting a clock signal into the slave device and detecting a status signal sent by the slave device; and stopping inputting the clock signal into the slave device when the status signal of the slave device indicates that the slave device is in an idle state. A working clock of a device module, such as a slave device, in a chip is controlled by using a status signal of the slave device and a bus signal, which prevents unnecessary circuit turnover from occurring to the device module in the chip in a non-working state, thereby achieving a purpose of reducing dynamic power consumption of the device module in the chip.
