Abstract: The present invention provides a control method of a receiver. The control method includes the steps of: when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and if the detection result indicates that the auxiliary signal has a preamble or a specific pattern, generating a wake-up control signal to wake up the receiver before successfully receiving the auxiliary signal having a wake-up command.

Abstract: A method is provided for manufacturing coffee by solid state fermentation, including the following steps: depositing coffee beans in a dust-free clean container; propagating a fungus with solid state fermentation; carrying out implantation process, wherein the fungus is implanted to the coffee beans contained in the dust-free clean container with a sterile operation, the fungus being one belonging to Eumycota, including at least one selected from Basidiomycotina and Ascomycotina; and performing a fermentation process. Also provided is a formula of the solid cultivation medium used in the method, which is suitable for both large-scale and small-scale production of fungi and is applicable to most fungi to not only increase the throughput as desired, but also provide a metabolic product containing pharmacologically active ingredients.
