The present disclosure relates to systems and methods for determining abnormal information associated with a vehicle. The systems may perform the methods to obtain real-time information associated with a bicycle and obtain reference information associated with the bicycle. The systems may also perform the methods to determine, based on the real-time information and the reference information, abnormal information associated with the bicycle, and transmit the abnormal information to a server or a terminal device associated with the bicycle according to a Narrow Band Internet of Things (NB-IoT) technique or a Long Range (LoRa) technique.

A disclosed component may include at least one split-ring resonator, which may be embedded within a material. The split ring resonator may be formed from a three-dimensional (3D) monolithic carbonaceous growth and may detect an electromagnetic ping emitted from a user device. The split ring resonator may generate an electromagnetic return signal in response to the electromagnetic ping. The electromagnetic return signal may indicate a state of the material in a position proximate to a respective split ring resonator. In some aspects, the split-ring resonator may resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the material is in a second state. A resonant frequency of the 3D monolithic carbonaceous growth may be based on physical characteristics of the material.

A method for checking the tire pressure of a vehicle (1), which vehicle comprises at least one vehicle wheel (3) and a vehicle body (2) which is supported elastically on the vehicle wheel (3). The wheel includes a tire (7), filled with gas, on which wheel the vehicle stands on a subsurface (8). The vehicle body (2) is loaded with an additional mass and thereby the vehicle body is stimulated into a mechanical oscillation (16) relative to the subsurface (8). A response signal (A), that characterizes the mechanical oscillation (16), is measured and analyzed, whereby at least one response value that characterizes the current gas pressure in the tire is determined.

A tire and wheel assembly includes a wheel having a portal and a tire mounted on the wheel, thereby forming a cavity. The assembly further includes a deflection sensor mounted on the wheel over the portal, at a location outside the cavity such that no portion of the deflection sensor is inside the cavity.

A method for evaluating the firmness of the ground on which is running a vehicle equipped with at least one mounted assembly having a radial stiffness k.sub.radial comprising a tyre casing having a crown, two sidewalls and two beads, equipped with a sensor sensitive to the circumferential curvature and positioned in line with the crown, comprises the following steps: Estimating a value of the curvature ρ.sub.A of the tire casing corresponding to first steady-state conditions of the tire casing in contact with the ground; and Evaluating the relative firmness of the ground with respect to the radial stiffness k.sub.radial of the mounted assembly as being a function of the value of the curvature ρ.sub.A of the tire casing.

In an embodiment, a system for wear monitoring, includes a wear surface, a metallic reflector embedded in the wear surface, a radio-wave transmitter, and a radio-wave receiver. The metallic reflector reflects radio waves transmitted by the radio-wave transmitter for detection by the radio wave receiver. Attenuation of the radio waves between transmission by the radio-wave transmitter and detection by the radio-wave receiver indicates a degree of wear of the wear surface.
