An information output device that can output the position of a load applied to the pedal is provided. A strain gauge is provided on the inner face of a crank of a bicycle and detects strain occurring in the crank. A cycle computer display unit displays an image showing the center position of the load applied to the pedal connected to the crank based on the tangential force and the torsional torque calculated based on the output values of the first strain gauge to the sixth strain gauge.

A sports-related measurement system that can include a forward facing camera, a global positioning satellite receiver, and the necessary data collection and processing capabilities to calculate the aerodynamic drag of a moving object. The data collected can include altitude, air pressure, air moisture content, temperature, and the like. The system can include a display for presenting data to the user and may also include memory for storage of data, photos, video, and the like. In some embodiments, the system may be configured as a bicycle computer adapted to mount on a bicycle.

A light projection system for a motorized kick scooter, comprising a light source and a controller. The light source is configured to illuminate a rider of the motorized kick scooter by projecting light onto the rider, and has at least three different light intensity states. Which of the at least three light intensity states the light source operates in is controlled by the controller, and depends on one or more properties of the motorized kick scooter.

The present invention relates to a two-wheeled vehicle accident reporting device having a retro-reflective cover, a deep learning recognition-based two-wheeled vehicle accident severity prediction server, and a two-wheeled vehicle accident severity prediction system including the same. The above reporting device includes: a body mounted on a two-wheeled vehicle; a retro-reflective cover having one end fixed to a lower end of the body, which is configured to be folded and unfolded in a scallop shape and reflects light; and a control board which is mounted on one side of the body, measures the speed and position of the two-wheeled vehicle using a plurality of sensors, and transmits accident occurrence information including speed information, impact amount information, location information and time information along with driver identification information through a wireless communication network to a two-wheeled vehicle accident severity prediction server when an accident occurs.

A method for plausibilizing a sensor signal of a single-track vehicle. The method includes: estimating gear ratios between a wheel speed of a wheel and a pedaling frequency of a pedal of a pedal unit and/or a drive speed of a drive of the single-track vehicle at multiple points in time; ascertaining a value of a reliability indicator based on the estimated gear ratios, the value of the reliability indicator being ascertained with the aid of a statistical parameter, in particular a variance, of the estimated gear ratios and/or a histogram of the estimated gear ratios; and plausibilizing the sensor signal based on a comparison of the value of the reliability indicator with a threshold value, the threshold value corresponding to a maximally permissible value of the reliability indicator.

A vehicle component includes a body having a plurality of layers where each of the plurality of layers is a composite material. The body includes a recess formed in one or more of the plurality of layers. A lighting material is disposed in the recess and includes a tube having a first end and a second end, and a light guide disposed within the tube and extending between the first end and the second end of the tube. A light source is adjacent to one or more of the first end and the second end of the tube. The light source is directed toward the light guide and configured to illuminated the lighting material. The recess is sized to receive the tube.

A network-enabled bicycle comprising a bicycle frame and an electronic device mounted to said bicycle frame is provide. The electronic device of network-enabled bicycle is configured to communicating with other network-enabled bicycles and/or a server via a wireless network access point. In general, a set of network-enabled bicycles are equipped with respective electronic devices which are programmed for allowing the bicycles in the set of bicycles to exchange data directly or indirectly with each other and/or exchange data directly or indirectly with the server via one or more of the wireless network access points connected to the server through a data network. In accordance with one specific example of implementation, the network-enabled bicycle connects to the wireless network access point over an open Wi-Fi connection.

A personal mobility includes a recognizer configured to recognize a surrounding situation, a transceiver configured to communicate with a wearable electronic device, and a controller configured to recognize the surrounding situation when receiving a user's gesture information through the transceiver, generate first hand signal information based on the recognized surrounding situation, recognize a changed surrounding situation in response to the first hand signal information, and generate second hand signal information based on the changed surrounding situation.
