Abstract: The disclosure relates to an antenna self-capacitance change detection method and apparatus, and related applications. The method includes: acquiring a total self-capacitance change of the antenna and a total self-capacitance change of the sensor electrode respectively; determining a first self-capacitance change of the antenna caused by a temperature change according to the total self-capacitance change of the sensor electrode and a preset self-capacitance change proportional coefficient; and determining a difference value between the total self-capacitance change and the first self-capacitance change of the antenna as a second self-capacitance change of the antenna caused by proximity of an object. The antenna self-capacitance change detection method can accurately determine the antenna self-capacitance change caused by the proximity of the object, to accurately determine whether there is an object approaching, thereby better controlling and adjusting the antenna transmitting power.

Abstract: A sensor electrode and an insulating body are coupled together by a hot melt member in a sensor of a steering wheel. The sensor electrode makes contact with the insulating body at first protrusions so as to form through holes in the hot melt member. The hot melt member is accordingly able to stretch easily due to the through holes, enabling a high extensibility for the sensor to be achieved.

Abstract: An aerosol-generating device is disclosed. The aerosol-generating device of the disclosure includes a cartridge having therein an insertion space formed to be elongated, a body coupled to the cartridge, a capacitance sensor disposed in the body so as to be adjacent to the insertion space in the cartridge coupled to the body, and a controller. The controller determines whether a stick is inserted into the insertion space based on a signal received from the capacitance sensor. When the stick is inserted into the insertion space, the controller determines whether the stick inserted into the insertion space is a used stick based on a signal received from the capacitance sensor.

Abstract: A detection method of a user of an apparatus is provided in which the apparatus is coupled to a charge variation sensor having a control unit and an electrode to detect an electric/electrostatic charge variation of the user. The detection method includes acquiring, through the electrode, a charge variation signal indicative of the presence of the user. A filtered signal is generated by filtering the charge variation signal. A feature signal is generated as a function of the filtered signal. A movement signal indicative of a movement of the user is generated as a function of the feature signal. A presence signal indicative of the presence of the user is generated as a function of the movement signal.

Abstract: A method for human movement classification includes a plurality of radio frequency (RF) antennas to expose a body surface of a human user to an E-field, at least a part of the human user positioned within a near-field region relative to the RF antennas. The plurality of RF antennas are scanned to determine ground-relative changes in electrical conditions. A differential-scanning subset of RF antennas are selected, including two or more RF antennas for which the changes in electrical conditions exceed a threshold. For each RF antenna in the differential-scanning subset, a set of antenna-relative changes in electrical conditions are determined by comparing the RF antenna to one or more other RF antennas in the differential-scanning subset as a plurality of pairs. Based at least in part on the ground-relative changes in electrical conditions and the antenna-relative changes in electrical conditions, a movement performed by the human user is classified.

An example apparatus includes a measurement circuit including a multiplexer, electrically connected to a plurality of inductive and capacitive sense circuits, for measuring one or more electrical characteristics in each of the inductive and capacitive sense circuits according to a predetermined time multiplexing scheme. The apparatus further includes a control and evaluation circuit for evaluating the measured electrical characteristics and determining at least one of a presence of a metallic object, a living object, a vehicle, or a type of vehicle, and a vehicle position based on changes in the measured electrical characteristics.
