The wearable article 200 comprises an electronics module 100. An electronics module holder 203 holds the electronics module 100. A visual marker 205 is located on an outside surface of the wearable article 200 at a position corresponding to the electronics module holder 203. The module 100 comprises a housing, and a processor 101 and electronics component 111 disposed within the housing. The electronics component 111 detects an object being brought into proximity with the electronics module 100. The visual marker 205 indicates the location of the electronics component 111 in the electronics module holder 203. The electronics component 111 generates a signal in response to the object being brought into the vicinity of the visual marker 205. The processor 101 is arranged to receive the signal generated by the electronics component 111 and is arranged to perform an action in response to receiving the signal.

A system for determining a direction of gaze of a user, comprising a set of electrodes arranged on earpieces, each electrode comprising a patch of compressible and electrically conducting foam material. The system further includes circuitry connected to the electrodes and configured to receive a set of voltage signals from a set of electrodes arranged on an audio endpoint worn by a user, multiplex said voltage signals into an input signal, remove a predicted central voltage from said input signal, to provide a detrended signal, and determine said gaze direction based on said detrended signal. Such conducting foam materials provide satisfactory bio-sensing performance for a wide range of compression levels and over time. In the case of on-ear headphones, the foam electrodes may be integrated in the cuffs with little or no effect on the comfort level.

A biosensing garment (100). The biosensing garment (100) comprises a garment (101). The biosensing garment (100) comprises an inner biosensing textile (200) disposed within the garment (101). The inner biosensing textile (200) comprises a textile panel (201). The inner biosensing textile comprises a biosensing unit (215) positioned on the textile panel (201) for measuring a biosignal of the wearer. A first region of the textile panel (201) is attached to the garment (101) such that the first region is unable to move relative to the garment (101). A second region of the textile panel (201) is able to move relative to the garment (101).

An object of the present invention is to provide a biological information measuring garment for cattle that allows easy measurement of biological information. The biological information measuring garment for cattle includes a clothing fabric; and an electrode provided on a skin-side surface of the clothing fabric, the clothing fabric including a first band portion on one end and a second band portion on another end in a body peripheral direction of the clothing fabric, and the clothing fabric having a larger area in a front-side region ahead of a region from the first band portion to the second band portion of the clothing fabric than an area in a back-side region behind the region from the first band portion to the second band portion.

An electrocardiogram detection device (000) whose housing (10) may be made of a conductive material, and the electrocardiogram detection device (000) may include a voltage holder circuit (30) configured to provide a target potential for the housing (10). A potential difference between the target potential provided by the voltage holder circuit (30) and a reference potential provided by an electrocardiogram detection circuit (20) for a third electrode (P3) is small. Therefore, in an ECG detection process, even if a user accidentally touches the housing (10) and causes the housing (10) to be conducted to the third electrode (P3), no leakage current is generated between the housing (10) and the third electrode (P3), or a small leakage current is generated between the housing (10) and the third electrode (P3). This can effectively reduce interference to an ECG signal and ensure accuracy of ECG detection.
