A dynamic information warning apparatus for a bicycle comprises a signal output module (3) used for displaying dynamic information of the bicycle in real time, and a control module (2) in signal connection with the signal output module (3) directly or through a mobile terminal. The control module (2) is in signal connection with a collection module (1) used for collecting motion state information of the bicycle. In working, the collection module (1) detects acceleration changes of a running bicycle in real time; a control input circuit (21) picks up steering information by means of a control rod, a key or the like; a corresponding signal is sent to the signal output module (3) directly or through the mobile terminal; the signal output module (3) visually indicates, according to a signal output by the control module (2), information such as braking force, braking states, left turning and right turning by means of the brightness, colors and a flickering mode of a warning unit (31) or through pictures or characters displayed by the warning unit (31); and pedestrians or vehicles behind the bicycle can be reminded to avoid the bicycle, so that a rider is self-protected and the riding risk is reduced.
A: Provided are a shift register, a gate driving circuit and a related display device, comprising: a first node control module (1); a second node control module (2); a third node control module (3); a first output module (4); and a second output module (5). The first node control module (1) adjusts an electrical potential at a first node (A). The second node control module (2) adjusts an electrical potential at a second node (B). The third node control module (3) adjusts an electrical potential at a third node (C). The first output module (4) adjusts an electrical potential at a driving signal output terminal (Output). The second output module (5) adjusts the electrical potential at the driving signal output terminal (Output). The shift register can control a duration of a scan signal outputted from the driving signal output terminal (Output) by changing only a duration of an inputted signal (Input) via cooperation of the above five modules, without needing to change clock signals (CK, CB), modify a circuit or change a related process. Therefore, complexity of a gate driving circuit and a related process can be reduced, thereby reducing costs.
B: An automatic-induction warning apparatus of a bicycle comprises a signal warning apparatus (1), a bicycle running state signal inductor (2), and a corresponding power supply. The bicycle running state signal inductor (2) is in signal connection with the signal warning apparatus (1). The signal warning apparatus (1) comprises a light-emitting warning pattern apparatus (11), a power supply circuit (12), a control circuit board (13), and a storage battery (14). The light-emitting warning pattern apparatus (11), the power supply circuit (12) and the storage battery (14) are electrically connected to the control circuit board (13). The bicycle running state signal inductor (2) transmits a signal to the control circuit board (13). The control circuit board (13) controls the light-emitting warning pattern apparatus (11) to display a light-emitting warning pattern (15) of a bicycle running state. The warning apparatus has a safety warning effect, and accordingly, occurrence of a vehicle collision accident can be avoided; and the warning apparatus is simple in structure, good in warning effect, safe and reliable.
C: A voice interactive recognition control system, comprising an audio signal acquisition module (1), an emotion recognition and determination module (2), a voice intelligent generation module (3), a voice output module (4), a control module (5) and a wireless transceiving module (6) connected to one another. The audio signal acquisition module (1) is used for acquiring and filtering external input voice information; the emotion recognition and determination module (2) is used for performing emotion recognition according to the external input voice information and determining a grammatical sense and an emotion category of the input voice; the voice intelligent generation module (3) is used for generating corresponding response voice information according to the grammatical sense and the emotion category of the input voice and sending the response voice information to the voice output module (4) or the control module (5); and the control module (5) is used for sending a control instruction to a corresponding intelligent device according to the received response voice information. Humanized control to the intelligent device is achieved by means of voice interaction.
D: A shift register and a drive method therefor, a grid drive circuit and a display device. The shift register comprises an input module (1), an output module (2) and an output control module (3); the output module (2) comprises a first output unit (21) and a second output unit (22), wherein a first node (P) controls the first output unit (21), the first output unit (21) controls signal transmission between a second clock signal input end (CK2) and a signal output end (OUT-PUT), a second node (Q) controls the second output unit (22), and the second output unit (22) controls signal transmission between a high/low level signal input end (VGH/VGL) and the signal output end (OUT-PUT); the output control module (3) comprises a first control unit (31) and a second control unit (32), wherein the first control unit (31) controls the level of the first node (P), and the second control unit (32) controls the level of the second node (Q). According to the solution of the present disclosure, impact of the change in a clock signal associated with the output module on an output signal can be reduced, thus improving the output effect of the shift register.
