Abstract: The present invention provides a smart helmet falling detection method and a smart helmet. The falling detection method includes following steps: initializing a system, determining a free fall, determining a collision, determining motionlessness, and generating an emergency signal according to a detection result that a motionlessness event occurs within a fourth duration after the collision event occurs. The smart helmet includes a three-axis acceleration sensor and a controller. For the smart helmet falling detection method and the smart helmet provided in the present invention, the acceleration is measured by the three-axis acceleration sensor installed on the smart helmet, and whether a riding falling event occurs is determined by analyzing change of the acceleration, and alarm is given according to the falling event, such that the problem of falling detection and calling for help in a riding process is solved in a targeted manner.

Abstract: The present disclosure is for a luminous helmet, comprising an outer shell configured to fit over a human head, an inner shell, a light-emitting band arranged along an elongated slit opening on the outer shell, and a light transmitting groove enclosing the light emitting band. In the manufacturing process, the outer shell was formed first, with a slit cut to match the light transmitting groove. The light-transmitting groove, comprising fixing grooves, engage fixing strips extending from edges of the outer shell along the slit opening. This structure then serves as a base to house the light-emitting band, and to receive pressure injection of the inner shell material.

Abstract: A light-emitting helmet is provided. The helmet includes a main body, a number of fixing members, and a number of light-emitting lamp strips. The main body includes a shell and inner layer. The shell includes an outer surface and a number of grooves defining in the outer surface. The fixing members are secured in the inner layer. The lamp strips are detachably mounted in the grooves by the fixing frames respectively. In addition, a light-emitting helmet manufacturing method is also provided.

Abstract: A method for manufacturing a helmet with hidden light sources includes: fixing a helmet housing with at least one light transmitting portion to a base mold; providing a light source protector and a light source belt, and fixing the light source protector to the light source belt, wherein the light source belt comprises a circuit board and a plurality of light sources mounted on, wherein the light source protector comprises a plurality of accommodating holes corresponding to the light sources one by one, and the light sources each are received in a corresponding accommodating hole and enclosed by the light source protector and the circuit board; aligning the light sources to the light transmitting portion and fixing the light source protector to an inner surface of the helmet housing; and injecting a buffer material into the base mold to form a base.

Abstract: The present disclosure is for a bicycle pedaling frequency sensor comprising a signal acquisition unit, a data transmission unit, and/or a data conversion unit. Pedaling frequency is obtained by recording and converting periodical changes of acceleration and/or of angular velocity in real time. This can be achieved by further incorporating a two axis, a three axis acceleration sensors, and/or gyroscope sensors. The pedaling frequency sensor communicates wirelessly with a computing terminal. It is powered and housed within the cavity of a shell, wherein the shell's outer surface is in thread fit with an inner surface of an expansion component. The expansion component allows the sensor to be inserted into and secured within hollow spaces on a bicycle's pedals and/or cranks.

Abstract: A method for manufacturing a helmet with hidden light source includes: providing a transparent base film and a screen printing plate, wherein the base film comprises a first portion and a second portion, and the screen printing plate covers and corresponds to the first portion; printing a lightproof ink layer on the second portion and the screen printing plate; removing the screen printing plate; coating a light transmitting ink layer on the lightproof ink layer; attaching at least one light source on the light transmitting ink layer corresponding to the first portion; and forming a helmet base to cover the at least one light source.

Abstract: A wireless communication system includes a number of peripheral devices, a wireless communication device, and a terminal. The wireless communication device includes a first communication module and a second communication module. The second communication module includes a host unit and a device unit. The host unit is used to be wirelessly connected to the peripheral devices. The terminal supports the first communication protocol is used to connect to the first communication module, and the terminal supports the second communication protocol is used to connect to the second communication module via the device unit thereof. A method using the wireless communication system is also provided.
