A saddle design system includes a memory configured to store saddle data, where the saddle data includes one or more rider-saddle pressure values. The system also includes a processor operatively coupled to the memory. The processor is configured to analyze the one or more rider-saddle pressure values. The processor is also configured to generate a lattice design for a saddle base based at least in part on the analysis of the one or more rider-saddle pressure values.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.

A snowmobile including a first warmer configured to generate heat in response to electrical current driven therethrough, and a second warmer configured to generate heat in response to electrical current driven therethrough. A control module is configured to accept a first temperature input from an operator of the snowmobile indicating a desired first temperature of the first warmer, and direct sufficient electrical current to the first warmer to generate heat equal to the first temperature input. The control module is further configured to accept a second temperature input from the operator of the snowmobile indicating a desired second temperature of the second warmer, and direct sufficient electrical current to the second warmer to generate heat equal to the second temperature input.

An apparatus including a computer processor; a computer memory, which communicates with the computer processor; and a sensor for detecting traffic signs, which communicates with the computer processor; wherein the computer memory includes data regarding a plurality of safety regulations for vehicles; and wherein the computer processor receives signals from the sensor, and determines whether a vehicle is violating one or more the safety regulations for vehicles based on the signals from the sensor and the data for the plurality of safety regulations stored in the computer memory, and provides a warning signal when a safety regulation is violated. The apparatus may further include a speedometer which communicates with the computer processor; wherein the computer processor is programmed by computer software stored in computer memory to receive speeds from the speedometer to determine if one or more of the safety regulations for vehicles have been violated.

A bicycle derailleur system is applied to a bicycle and includes a controller, a camera, a derailleur assembly, and the memory device that are electrically connected to the controller. The camera records a real-time video of a road ahead. When the derailleur assembly is operated to shift, the derailleur assembly sends a chain shifting signal to drive the controller to process the video captured by the camera to obtain a section of video between a predetermined time before and after the chain shifting signal. The controller stores the section of the video along with information in the chain shifting signal to the memory device, to establish a basis for image similarity comparison. When the bicycle derailleur system is operated automatically, the image similarity comparison between real-time video recorded by the camera and the sections of the videos stored in the memory device is conducted to determine whether to shift.

The present disclosure provides an apparatus configured to couple to a bicycle and act as a handlebar grip. The apparatus is equipped with a GPS unit, a controller, and a wireless communications module for communicating with a user device such as a smartphone. The positioning data of the apparatus, and thus of a bicycle to which it is affixed, is tracked and recorded, and can be used to calculate various useful metrics. The GPS functionality also allows for increased security and theft prevention features.

Provided are a new antenna, a bicycle including the new antenna, a display apparatus including the new antenna, and an unmanned aircraft including the new antenna. An antenna includes a first conductor, a second conductor facing the first conductor in a first direction, a third conductor, a fourth conductor, and a feeding line electromagnetically connected to the third conductor. The third conductor is located between the first conductor and the second conductor, apart from the first conductor and the second conductor, and extends in the first direction. The fourth conductor is connected to the first conductor and the second conductor and extends in the first direction. The first conductor and the second conductor are capacitively connected via the third conductor. The antenna is disposed in a bicycle component of a bicycle such that the fourth conductor faces the bicycle component.

A vehicle operation and riding data collection device includes a housing defining an internal cavity, a power source supported by the housing in the internal cavity, a communications element supported by the housing in the internal cavity, a global positioning element supported by the housing in the internal cavity, at least one sensor supported by the housing in the internal cavity, and a processor configured to manage the power source, the communications element, the global positioning element, and the at least one sensor, to perform functional features corresponding to providing vehicle operation and riding data to, and receiving input from, a user.

To provide a human-powered vehicle control device configured to perform shifting in accordance with situations, a control device is configured to control a transmission of a human-powered vehicle. The control device comprises an electronic controller configured to control the transmission. The electronic controller includes at least one shifting condition for actuating the transmission to shift a transmission ratio. The electronic controller holds the shifting condition that is related with riding-related information of the human-powered vehicle in a case where the human-powered vehicle is in a riding convergence state.
