Method for checking and/or monitoring the use of a tire
A method for checking and/or monitoring the use of a tire (1) mounted on a vehicle (7), comprises the following steps: acquisition, by a microphone (10) arranged inside the tire, of an acoustic response of said tire (1) obtained under the effect of a pulsed mechanical stress thereon, and processing of said response in the frequency domain, characterized in that said processing identifies, in the response in the frequency domain, two spectrum spikes situated on either side of a reference frequency corresponding to the first cavity mode of the tire and, as a function of the frequency deviation between the two duly identified spikes, determines information relating to at least one parameter of use of the tire.
Pressure sensing assembly for a bicycle wheel
A pressure sensing assembly configured to be attached to a bicycle wheel having a tire and a rim mounted to the tire. The pressure sensing assembly includes a housing, a pressure transmitting member, a sensing chamber defined by the housing and the pressure transmitting member, and a sensing element. The pressure transmitting member is coupled the housing and has a central portion offset from the plane in a first direction. The sensing element is offset from the plane in a second direction opposite the first direction. The pressure transmitting member is configured to transmit a pressure in the tire to the sensing element via the sensing chamber.

Force Measuring Device for Measuring Web Tensions of a Running Material Web
The present invention relates to a force measuring device (20) for measuring web tensions of a running material web (10) that comprises a longitudinal direction defined by the running direction, and a transverse direction, the force measuring device (20) comprising an axle (22) and, supported on the axle, a measuring roll (30) wrapped around by the material web. Here, according to the present invention, it is provided that the measuring roll is formed as a segmented measuring roll (30) having two or more measuring segments (32) that are slidable separately on the axle (22) and are lockable in a measuring position on the axle in order to position the measuring segments (32) in the transverse direction of the material web (10) in accordance with desired measuring positions such that longitudinal sections (12) of the material web wrap around one measuring segment (32) each. The measuring segments (32) each comprise a load cell (36) that serves to determine the web tension of the longitudinal section (12) of the material web wrapped around the respective measuring segment (32) and that provides a mount with which the measuring segment (32) sits on the axle (22). The axle (22) is furnished with electrical conductors that extend substantially in the axial direction across the entire width (26), that are contactable at every position axially and with which the measuring signals provided by the load cells (36) of the measuring segments (22) are conductible to an evaluation unit arranged at an axle end (28).
