A system and method for calibrating one or more sensing features for a furniture item detection is provided. More particularly, embodiments relate to determining a first noise state associated with an environment of the furniture item based on a first measured noise received from one or more sensors associated with the furniture item. A first baseline noise level for the furniture item can be generated based on filtering the first noise state associated with the environment of the furniture item. A second noise state associated with the environment of the furniture item can be determined based on a second measured noise received from the one or more sensors associated with the furniture item. A second baseline noise level for the furniture item can be generated based on filtering the second noise state associated with the environment of the furniture item. The first baseline noise level can then be adjusted to the second baseline noise level.

A capacitive proximity sensor for use in mobile devices such as smartphones and connected tables, in which it is used to switch off a display (70) when the device is brought to the ear. The capacitive sensor is arranged for rejecting spurious detection induced, for example, by condensation, ingress of water, or thermal drift, based on the time variations of a capacity seen by the readout circuit (80), Additionally, the proximity sensor may integrate signals form motion sensors, temperature sensors or other sensors, to discriminate spurious proximity signals.

The handle including: an electrode having a capacitance, and a device for measuring the variation in capacitance, a low-frequency antenna situated close to the electrode, the emissions of the low-frequency antenna bringing about disturbances in the operation of the device for measuring the variation in the capacitance. The method proposes that a new adaptive approach detection threshold be calculated, depending on an average of the previous measured variations in the capacitance, calculated over a predetermined time interval, the measured variations being weighted by a factor depending on a difference between each measured variation and the average of the variations calculated previously over a previous predetermined time interval, the approach detection being confirmed if the measured variation is higher than the new adaptive threshold.

A touch detecting apparatus includes an electrostatic sensor provided on an object; and a processor configured to detect whether a hand touches the object based on a capacitance measured by the electrostatic sensor. The processor is configured to, in response to the capacitance being greater than or equal to a first touch threshold, detect that the hand touches the object, and, for a second predetermined time from when a change amount of the capacitance during a first predetermined time becomes greater than or equal to a noise threshold, continue a state where a correction value has been added to the first touch threshold.

Broadly speaking, embodiments of the present techniques provide a method for identifying user interactions with an electronic apparatus. It is desirable to provide feedback to a user each time they interact with certain parts of the electronic apparatus. However, an actuator used to provide the feedback may interfere with a signal output by a sensor, such that it becomes difficult to identify true subsequent user interactions. The present techniques provide ways to process a raw signal output by a sensor to enable user interactions to be more easily distinguished from the interference (e.g. cross-talk).
