This application presents a solution for measuring different physical parameters from the felt and its surrounding environment, such as: pressure, temperature, humidity, pH, airflow and the degradation of the felt. It is disclosed a monitoring system, comprising: an independent measuring unit fixed in a felt, comprising at least one of the following sensors: temperature, humidity, pH, pressure or air flow; a central acquisition unit comprising a microcontroller, a real-time clock, a communication transceiver connected to at least one independent measuring unit and a communication transceiver connected to a computing device; and a polymeric encapsulation material layer. Applications for this technology are the monitoring of the felt and its surrounding environment in, for example, dry filtration, laundries, wet filtration and other suitable applications. Although the system is focused specifically on felt, the same principles could be applied to other types of fabrics with no further modifications to the system.

A foot-operated controller of a sewing machine including a first pedal that input a number of revolution of a sewing machine motor by stepping of a user, a second pedal pressed by the user, a main body that supports the first pedal, and a support unit that supports the second pedal, in which the support unit is selectively attachable in disposition where the second pedal is on the left side of the first pedal and disposition where the second pedal is on the right side of the first pedal. In both cases where the second pedal is on the left side of the first pedal and the right side of the first pedal, across an interval between the main body and the support unit, it is possible to detect the pressing to the second pedal with respect to the second element.
