摘要： The invention relates to an algorithm for detecting activation of a tactile pressure sensor having a mechanic structure that includes the steps of: (a) measuring periodically an input quantity (V0; f0) of the sensor, when it is not pressed, the period being set according to sensor dynamic requirements; (b) computing a current idle quantity (Vidle; fidle) depending on the input quantity (V0; f0) measured at step a); (c) computing an activation threshold (ΔVP; ΔfP) based on a quantity characterization of the sensor mechanic structure and depending on the idle quantity (Vidle; fidle) defined at step b); (d) comparing the sensor input quantity (V0; f0) with the last defined idle quantity (Vidle; fidle) increased by the activation threshold (ΔVP; ΔfP) computed in step c) in order to determine whether the sensor is pressed or not.

摘要： Pressure sensitive transducer assembly that includes a force sensing resistor. The force sensing resistor includes: first and second substrates; at least a first and a second electrically conductive traces on the inner surface of the first substrate including interdigitated fingers defining a sensitive area; and a resistive layer facing the sensitive area. The force sensing resistor includes an auxiliary trace on the inner surface of the first substrate connecting the first trace to the second trace through a constant resistance that is not dependent on the force applied to the substrates. The constant resistance being of a value largely greater than the value of the variable resistance which can be measured indirectly between the fingers when an external force is applied to the substrates. A system and a control method are also proposed.
