Abstract: A foot presence sensor system for an active article of footwear can include a sensor housing configured to be disposed at or in an insole of the article, and a controller circuit, disposed within the sensor housing, configured to trigger one or more automated functions of the footwear based on a foot presence indication. In an example, the sensor system includes a capacitive or magnetic sensor configured to sense changes in a body's proximity to the sensor in footwear. Characteristics of the sensed proximity can be used to update an automated footwear function, such as an automatic lacing function, or can be used to determine a step count, foot strike force, a rate of travel, or other information about a foot or about the footwear.

Abstract: Transducer systems disclosed herein include self-sensing capabilities. In particular, electrostatic transducers include a low voltage electrode and a high voltage electrode. A low voltage sensing unit is coupled with the low voltage electrode of the electrostatic transducer. The low voltage sensing unit is configured to measure a capacitance of the electrostatic transducer, from which displacement of the electrostatic transducer may be calculated. High voltage drive signals received by the high voltage electrode during actuation may be isolated from the low voltage sensing unit. The isolation may be provided by dielectric material of the electrostatic transducer, a voltage suppression component, and/or a voltage suppression module comprising a low impedance ground path. In the event of an electrical failure of the transducer, the low voltage sensing unit may be isolated from high voltages.

Abstract: A composite detection sensor includes a sensor cable including not less than three conductive electrode wires and a resilient insulation covering collectively the electrode wires and holding the electrode wires that are circumferentially spaced from each other, and a capacitance measurement unit for measuring capacitance between each two electrode wires and between each electrode wire and the ground. The capacitance measurement unit may include plural inter-wire capacitance measuring portions for measuring capacitance between the electrode wires, a wire-ground capacitance measuring portion for measuring capacitance between the electrode wires and the ground, and a switching means switchable between a first connection state and a second connection state, the first connection state being a state in which the electrode wires are connected to the inter-wire capacitance measuring portions, and the second connection state being a state in which the electrode wires are connected to the wire-ground capacitance measuring portion.

The capacitive detection device includes a differential amplifier, a first capacitor, a second capacitor, a charging module, a control module and a calculation module. The charging module is controlled by the control module to charge two capacitors to be detected, then an amount of charge of the capacitors to be detected is transferred to the first capacitor and the second capacitor, and a signal is amplified through the differential amplifier and the amplified signal is output to the calculation module, so that a capacitance difference of different capacitors may be obtained through a voltage at an output terminal of the differential amplifier, a supply voltage of the charging module, a capacitance of the first capacitor and a capacitance of the second capacitor.
