Abstract: An optical communication system includes an optical module and a host. The optical module has a fiber connector and a laser condition pin, wherein the fiber connector is configured to connect to a laser output of an external laser source. The optical module is configured to set an output of the laser condition pin to have a first value when detecting a laser beam through the fiber connector. The host is connected to the laser condition pin and has a control connector, wherein the control connector is configured to connect to the external laser source. The host is configured to output a release signal through the control connector when detecting the first value on the laser condition pin, wherein the release signal changes the laser output from outputting a laser beam having a first power to outputting a laser beam having a second power higher than the first power.

Abstract: A serial peripheral interface circuit includes a serial peripheral interface device with a master-in-slave-out (MISO) line, a master-out-slave-in (MOSI) line, a serial clock (SCLK) line and a slave select (SS) line, a first conducting line, a second conducting line, a first resistor connecting the MISO line and the first conducting line, and a second resistor connecting the MOSI line and the second conducting line.

Abstract: A multi-leaf solar energy supplying apparatus includes an energy converting module and an electrical power storing module. The energy converting module includes a solar energy board having a plurality of leaves for converting solar energy into electrical power. The electrical power storing module is electrically connected with the energy converting module for receiving electrical power to charge a secondary battery. Therefore, the secondary battery provides at least one output voltage to an application system. Furthermore, the energy converting module further includes at least one first power transmission port. When the energy converting module is separated from the electrical power storing module, the energy converting module is connected with the application system via the first power transmission port and provides a voltage to the application system. Thereby, the goals of charging and supplying power via solar power, and offering a power source that can be used anywhere are achieved.

Abstract: A cover member is adapted for use with a food processor, and includes a cover body formed with a straight rod passage and a food passage that branches from the rod passage. The rod passage has an open inner passage portion, and an open outer passage portion opposite to the inner passage portion in a vertical direction. The food passage has an open inlet end adjacent to the outer passage portion of the rod passage, an open outlet end in spatial communication with the inner passage portion of the rod passage, and a guide passage portion between the inlet and outlet ends. The guide passage portion is capable of guiding a food item fed into the food passage via the open inlet end to move into the inner passage portion of the rod passage via the open outlet end.
