The control module (1) is connected to the IO expansion module (2), the display module (3), the impedance measuring module (4), the communication module (6), the voltage sampling module (7), the data storage module (8) and the clock module (9). The IO expansion module (2) is connected to the display module (3), the impedance measuring module (4), the communication module (6), the sound module (10) and the system state indicating module (11). The present invention is convenient to carry and capable of being extensively applied in various biological impedance analysis occasions.
B: A vest for shooting games comprises a vest body, a main control unit (1) disposed on the vest body, and a laser sensing unit (2) for receiving a laser signal from a laser transmission gun, a vibration sensor (3) for acquiring a vibration frequency of the vest body, micro vibrating motors (4) for driving the vest body to vibrate, a storage unit (8) at least storing a simulated life value of the vest, and touch buttons (71, 72, 73) disposed at the left side, right side and rear side of the vest respectively, which are connected to the main control unit (1). The number of the micro vibrating motors (4) is two, which are disposed around the touch buttons (71, 72) at the left side and right side of the vest in a one-to-one corresponding manner respectively.
C: A portable record reminding apparatus and a processing method for voice input and recognition thereof, wherein the device comprises a housing, a rechargeable battery, a main control MCU, an input device, a display screen, an information storage device, a charging and discharging circuit, a voice processing device and an electromagnetic vibration module which are installed in the housing. The main control MCU is connected to the input device, the display screen, the information storage device, the charging and discharging circuit, the voice processing device and the electromagnetic vibration module respectively, thereby achieving a collection of multiple functions. A user can add and modify alarm clock settings by means of voice. Schedule management can be set by means of voice. Reminding can be performed by means of vibration and the like according to a set alarm clock time. Voice can be recorded to be stored in an information storage device. And voice recognition of a dialect language can further be supported via the main control MCU. The whole device has a small volume, a high integration level and a comprehensive function, and is suitable for large-scale promotion.
D: A station guiding system based on optical transmission communication, comprising: a display subsystem for displaying information; a storage module for storing data; a scanning interface module for abutting the display subsystem against the storage module, and a control module for controlling the working mode of the display subsystem by means of optical transmission communication. The display subsystem comprises a plurality of display screens which are successively arranged along floors of a railway station; each display screen corresponds to one floor and is provided at an entrance of a main channel of the corresponding floor; the display screen is provided with a floor number display module for displaying the number of the current floor; a waiting information display module for displaying the waiting information of the current floor; a delayed train information display module for displaying information of delayed trains; a clock display module for displaying the current time; and a prompt information display module for displaying prompt information. The station guiding system can conveniently guide passengers to rapidly find out corresponding train numbers and boarding points in the railway station.
