The mechanical coupling may be maintained using friction or using a positively engaging mechanism, for example.

Beneficially, the removable electronic module 100 may contain all of the components required for data transmission and processing such that the garment 200 only comprises the sensor components and communication pathways. In this way, manufacture of the garment 200 may be simplified. In addition, it may be easier to clean a garment 200 which has fewer electronic components attached thereto or incorporated therein. Furthermore, the removable electronic module 100 may be easier to maintain and/or troubleshoot than embedded electronics. The electronic module 100 may comprise flexible electronics such as a flexible printed circuit (FPC). The electronic module 100 may be configured to be electrically coupled to the garment 200.

It may be desirable to avoid direct contact of the electronic module 100 with the wearer's skin while the garment 200 is being worn. It may be desirable to avoid the electronic module 100 coming into contact with sweat or moisture on the wearer's skin or other sources of moisture such as from rain or a shower. The electronic module 100 may be provided with a waterproof coating or waterproof casing. For example, the electronic module 100 may be provided with a silicone casing.

The pocket may be provided with a waterproof lining in order to prevent the electronic module 100 from coming into contact with moisture.

Referring to Figure 2, there is shown a simplified schematic diagram of an example electronics module 100 according to aspects of the present disclosure. The electronics module 100 comprises a processor 101 configured to process signals sensed by a sensing component of the electronics module 100 and/or the garment 200. The signals relate to the activity of a user wearing the garment 200. The processor 101 is configured to process the signals so as to determine whether the activity of the user is within a predetermined allowable range. The electronics module 100 comprises a light source 103 configured to emit light based on the determination by the processor 101. The emitted light is for indicating whether the activity of the user is within the predetermined allowable range. The garment 200 is constructed such that the emitted light 102 is visible from the outside surface 201 of the garment 200.

The light source 103 is configured to emit light having a first property when the activity of the user is determined to be within the predetermined allowable range. The first property may comprise one or more of a colour, intensity, pattern, frequency, or switching on/off (the light source 103 may flicker or blink in a particular way) amongst others.

The light source 103 is configured to emit light having a property other than the first property when the activity of the user is determined to be outside of the predetermined allowable range. In some examples, the light source 103 is configured to emit light having a first colourwhen the activity of the user is determined to be within the predetermined allowable range. In some examples, the light source 103 is configured to emit light having a colour other than the first colour when the activity of the user is determined to be outside of the predetermined allowable range.

In some examples, the light source 103 is configured to emit light having a second property when the activity of the user is determined to be outside of the predetermined allowable range but within a predetermined distance of the allowable range.

In some examples, the light source 103 is configured to emit light having a third property when the activity of the user is outside of the predetermined allowable range and more than the predetermined distance from the predetermined allowable range.

In some examples, the user wearing the garment 200 may desire to undergo exercise while operating in a certain heart rate zone. Heart rate zones are commonly used to indicate levels of exertion during exercise/competition. Heart rate zones are ranges that define the upper and lower limits of training intensities. Heart rate zones are calculated using a predicted maximum heart rate (HRMax) which can be determined based on factors such as the age of the user. Each heart rate one is based on an individual's maximum heart rate (HRMax). There are a number of ways to calculate HRMax. In some examples, HRMax is determined using the formula HRMax= 220-(0.7xAge). Age refers to the age of the user in years.

A first heart rate zone, also known as training zone 1, may be defined as 50 -60 % HRMax. A user may desire to remain in training zone 1 if they are a novice exerciser, exercising for weight management, or recovering from an injury. A second heart-rate zone, also known as training zone 2, may be defined as 60%-70% HRMax. This may be referred to as the fat-burning zone. Training zone 2 is beneficial for increasing aerobic resistance, burning fat, and strengthening body tolerance for higher intensity training. A third heart rate zone, also known as training zone 3, may be defined as 70%-80% HRMax. This may be referred to as the aerobic zone. Training zone 3 is beneficial for enhancing aerobic power and improving blood circulation. A fourth heart rate zone, also known as training zone 4, may be defined as 80%-90% HRMax. This may be referred to as the anaerobic zone. Training zone 4 is beneficial for improving anaerobic tolerance and high speed endurance. A fifth heart rate zone, also known as training zone 5, may be defined as 90%-100% HRMax. This may be referred to as the V02 max zone and is beneficial fortoning the neuromuscular system and increasing maximum sprint race speed.

A user may prefer to remain in a desired heart rate zone (such as the second heart rate zone) during their exercise. The sensing component measures heart rate activity (cardiac activity). The sensing component may comprise one or more ECG electrodes for measuring heart rate activity or other known types of sensing components for measuring heart rate activity. The processor 101 receives the heart rate activity signals and determines from the heart rate activity signals and optionally data from other sensing components, the heart rate zone the user is in. If the processor 101 determines that the user is in the desired heart rate zone, the processor 101 controls the light source 103 to emit light having a first property.

The first property may be, for example, green-coloured light. If the processor 101 determines that the user's heart rate activity is just outside of the desired heart rate zone (e.g. within 10% of the desired heart rate zone), the processor 101 controls the light source 103 to emit light having a second property. The second property may be, for example, amber-coloured light. The light source 103 may comprise a plurality of light-emitting diodes (LEDs) so as to emit light having different colours. For example, the light source 103 may comprise a Red Green Blue (RGB) LED package comprising a Red LED, a Green LED, and a Blue LED. If the processor 101 determines that the user's heart rate activity is more than a predetermined distance of the desired heart rate zone (e.g. more than 10% outside of the desired heart rate zone), the processor 101 controls the light source 103 to emit light having a third property. The third property may be, for example, red-coloured light. In this way, the electronics module 100 uses a traffic light system to provide easy to understand feedback about the performance of the user. This feedback may be clearly visible to the user or third party such as team-mate, coach, personal trainer, or clinician.

In some examples, it may be desirable to use the garment according to aspects of the present disclosure to monitor users undergoing physically intensive activity while in an athletic or work environment. It may be desirable to use the light source to emit light having a property that indicates the amount of time the user has spent in different heart-rate zones. This may be desirable to indicate to the user or other person such as a supervisor, coach, personal trainer, or clinician the amount of time the user as spent in different hear-rate zones.

For example, if the user remains in heart rates zones 1 and 2 the light source 103 may be arranged emit light having first property (e.g. green light) to indicate that the user is undergoing safe activity.

If the user spends a continuous period of between 30 and 45 minutes in heart rate zone 3 the light source may emit light having second property (e.g. amber light) to indicate that the user's activity should be monitored. If the user spends a continuous period of more than 45 minutes in heart rate zone 3 then the light source may emit light having third property (e.g. red light) to indicate that the user is fatigued.

If the user spends a continuous period of between 2 and 4 minutes in heart rate zone 4 the light source may emit light having second property (e.g. amber light) to indicate that the user's activity should be monitored. If the user spends a continuous period of more than 4 minutes in heart rate zone 4 then the light source may emit light having third property (e.g. red light) to indicate that the user is fatigued.

If the user spends a continuous period of between 0.5 and 1 minute in heart rate zone 5 the light source may emit light having second property (e.g. amber light) to indicate that the user's activity should be monitored. If the user spends a continuous period of more than 1 minutes in heart rate zone 5 then the light source may emit light having third property (e.g. red light) to indicate that the user is fatigued.

It will be appreciated that these ranges are just examples. The skilled person will appreciate that any desired range may be set based on factors such as the type of activity and the fitness of the user.

In some examples, it may be desirable to determine the heart rate recovery for a user wearing the garment 200. Heart Rate Recovery is a useful measure of fitness and, longitudinally, can also be an indicator of training fatigue. Heart rate recovery is measured as the difference between the heart rate immediately at the end of a period of exercise and the heart rate 1 minute after the cessation of exercise. Generally, the fitter the individual, the greater the drop between exercising heart rate and the heart rate one minute after cessation of exercise. Typically, the drop is measured after exercising for at least three minutes at 60-80% of theoretical maximum heartrate. In some examples, a concerning score will be a less than 12 bpm drop, a good score will be between a 25-30 bpm drop and an excellent score will be between a 50-60 bpm drop. Of course, other numerical ranges are within the scope of the present disclosure. The light source 103 can emit light having a first property (e.g. green light) when the user has the excellent score, light having a second property (e.g. amber light) when the user has a good score, and light having a third property (e.g. red light) when the user has a concerning score.

In some examples, the light source 103 may emit light to indicate whether the user is at risk of injury. Light having a first property (e.g. green light) may indicate that the user is not at risk of injury. Light having a second property (e.g. amber light) may indicate that the user should be monitored. Light having a third property (e.g. red light) may indicate that the user is at risk of injury. The risk of injury may be derived from heart rate data by assessing the amount of time an individual spends in heart rate zones.

In some examples, the light source 103 may emit light based on the orthostatic heart rate of the user. The orthostatic heart rate can be used to analyse an individual's training readiness. It measures the difference between their resting heart rate and their standing heart rate. In an example operation for determining the orthostatic heart rate, a user may first lie down and rest for a period of time. Typically, the period of time is at least three minutes. The heart rate of the user is recorded during this time. The user then stands up and the heart rate may be measured shortly after standing (peak heart rate) or several minutes after standing (stabilised heart rate) or both peak and stabilised heart rate may be measured. The difference between the standing and the prone heart rate is determined so as to obtain the orthostatic heart rate.

In example operation, the light source 103 may output light having a first property (e.g. green light) when the difference between the lying and standing heart rate is within an allowable range indicating that the user is rested. The allowable range may be between 5 and 9 beats per minute, bpm. The light source 103 may output light having a second property (e.g. amber light) when the difference between the lying and standing heart rate is outside of the allowable range but within a predetermined distance of the allowable range. The light source 103 may output light having the second property when the difference is between 10 and 30 bpm. The output light having the second property will indicate that the user is under recovered and should lighten their training load. The light source 103 may output light having a third property (e.g. red light) when the difference between the lying and standing heart rate is outside of the allowable range and more than the predetermined distance from the allowable range. The light source 103 may output light having the third property when the difference is less than 5 bpm or more than 30 bpm. The output light having the third property will indicate that the user should seek medical evaluation and not undertake exercise.

A similar measure of over-training or under-recovery can be obtained by looking for variances in the Average Standing HR -Standing HR. If the variance was greater than 10-15 beats per minute, it may be deemed to be a sign of over-training. If there is a gradual increase in the variance over time, it suggests that the athlete was heading towards over-training. In an example operation, a user may lie down and rest for a period of time (e.g. 10 minutes). The user may then stand up and record the heart rate shortly thereafter (e.g. 12 seconds after standing up). At a later time (e.g. 90 seconds after standing up) the user may record their heart rate again. The difference between the first and second standing heart rates given an indication of whether the user is overtrained.

In example operation, the light source 103 may output light having a first property (e.g. green light) when the difference between the first and second standing heart rates is within an allowable range indicating that the user is rested. The allowable range may be less than 5 beats per minute, bpm. The light source 103 may output light having a second property (e.g amber light) when the difference between the first and second standing heart rates is outside of the allowable range but within a predetermined distance of the allowable range. The light source 103 may output light having the second property when the difference is between 5 and 10 bpm. The output light having the second property will indicate that the user is possibly over-trained and should be monitored. The light source 103 may output light having a third property (e.g. red light) when the difference between the first and second standing heart rates is outside of the allowable range and more than the predetermined distance from the allowable range. The light source 103 may output light having the third property when the difference is more than 10 bpm. The output light having the third property will indicate that the user is over-trained and should undertake a lighter training load.

The light source 103 may emit light based on the core temperature of the user. The core temperature may be measured by temperature sensors incorporated into the electronics module 100 and/or the garment 200. Alternatively, the core temperature may be estimated based on the variation in heart rate as measured by heart rate sensors. An example approach for estimating core temperature from the heart rate is the Buller algorithm as disclosed in Buller, Mark & Thanon, William & Cheuvront, Samuel & Montain, Scott & Kenefick, Robert & Castellani, John & Latzka, William & Roberts, Warren & Richter, Mark & Jenkins, Odest & Hoyt, Reed. (2013). Estimation of human core temperature from sequential heart rate observations.

Physiological measurement. 34. 781-798. 10.1088/0967-3334/34/7/781. The disclosures of which are hereby incorporated by reference.

In an example use case, the light source 103 may emit light having a first property (e.g. green light) when the user's core body temperature is determined to be within a safe range. The safe range may be between 36.5 degrees Celsius and 37.5 degrees Celsius, for example. The light source 103 may emit light having a second property (e.g. amber light) when the users core body temperature is outside of the safe range but within 0.5 degrees Celsius of the safe range. For example, light having the second property may be emitted when the user's core body temperature is between 36 degrees Celsius and 36.5 degrees Celsius or between 37.5 degrees Celsius and 38 degrees Celsius. The light having the second property indicates to the user or other observer that the user can continue their activity but needs to be monitored closely. The light source 103 may emit light having the third property (e.g. red light) when the user's core body temperature is less than 36 degrees Celsius or greater than 38 degrees Celsius. The light having the third property indicates to the user or other observer that the user should stop their exercise and potentially seek medical attention. Of course, these numerical ranges are just examples and other ranges may be set as appropriate by the skilled person.

The light source 103 may emit light based on hydration level of the user. The hydration level may be determined from hydration sensors or may be estimated based on factors such as heart rate and core body temperature. The light source may emit light having different properties to indicate whether hydration level is safe, needs to be monitored, or a cause for concern.

The present disclosure is not limited to these examples. Any or a combination of these examples may be used. In addition or separately, the light source 103 103 may emit light to indicate the users exercise readiness, whether they are due a rest period or need to seek medical attention, or whether the posture of the user is correct, needs monitoring or is a cause for concern.

Referring to Figure 3, there is shown a simplified schematic diagram of another example electronics module 100 according to aspects of the present disclosure. The electronics module 100 comprises the processor 101 and the light source 103 of Figure 2. The electronics module 100 further comprises an input unit 111. The input unit 111 is configured to receive a user input for selecting an operational mode. The processor 101 is configured to process the signals received from the sensing component so as to determine whether the activity of the user is within a predetermined allowable range for the selected operational mode. The operational modes may comprise different exercise modes (e.g. low intensity exercise, medium intensity exercise or high intensity exercise) these different exercise modes may be associated with different desired heart rate zones. The operational modes may comprise different activities such as walking, running, swimming, weight lifting and cycling which may be associated with different desired activity levels, postures, heart rate zones, etc. The present disclosure is not limited to any particular operational modes.

In some examples, the input unit 111 comprises a sensor 111 arranged to detect an object (such as the mobile device 300 of Figure 1) being brought into the electronics module 100. In particular, the sensor 111 is a motion sensor that is arranged to detect a displacement of the electronics module 100 caused by the object being brought into proximity with the electronics module 100. These displacements of the electronics module 100 may be caused by the object being tapped against the electronics module 100. Physical contact between the object and the electronics module 100 is not required as the electronics module 100 may be in a pocket of a wearable article. This means that there may be a fabric barrier between the electronics module 100 and the object. In any event, the electronics module 100 being brought into contact with the fabric of the pocket will cause an impulse to be applied to the electronics module 100 which will be sensed by the sensor 111.

The sensor 111 may an inertial measurement unit. The inertial measurement unit may comprise an accelerometer and optionally one or both of a gyroscope and a magnetometer. A gyroscope/magnetometer is not required in all examples, and instead only an accelerometer may be provided or a gyroscope/magnetometer may be present but put into a low power state. A processor of the sensor 111 may perform processing tasks to classify different types of detected motion. The processor of the sensor 111 may in particular perform machine-learning functions so as to perform this classification. Performing the processing operations on the sensor 111 rather than the processor 101 is beneficial as it reduces power consumption, and leaves processor 101 free to perform other tasks. In addition, it allows for motion events to be detected even when the processor 101 is operating in a low power mode. The sensor 111 communicates with the processor 101 over a serial protocol such as the Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C), Controller Area Network (CAN), and Recommended Standard 232 (RS-232). Other serial protocols are within the scope of the present disclosure. The sensor 111 is also able to send interrupt signals to the processor 101 when required so as to transition the processor 101 from a low power model to a normal power mode when a motion event is detected. The interrupt signals may be transmitted via one or more dedicated interrupt pins.

The sensor 111 may not just be used for cycling between different operational modes. The sensor 111 may also be used in determining whether the user is within the predetermined allowable range. This is particularly the case for motion sensors which can be used for motion and posture analysis.

Referring to Figure 4, there is shown another example system 10 according to aspects of the present disclosure. In this system 10 a plurality, three in this example, of garments 200a, 200b, 200c are provided. The garments 200a, 200b, 200c are each worn by a different user 11a, 11b, 11c. Electronics modules in accordance with the present disclosure are incorporated into the garments 200a, 200b. 200c and emit light 102a, 102b, 102c to indicate whether the activity of the user 11a, 11 b, 11c wearing the garment 200a, 200b, 200c is within the predetermined allowable range. The garments 200a, 200b, 200c are constructed such that the emitted light 102a, 102b, 102c is visible from the outside surfaces of the garments 200a, 200b, 200c.

The users 11a, 11b, 11c are undergoing a training session and are being monitored by a coach 12. The coach 12 may want to quickly tell if the player if adhering to the training regime. For example, the coach 12 may want to quickly tell whether the users 11a, 11 b, 11c, are operating in the correct heart rate zone or have the correct posture. The emitted light 102a, 102b, 102c from the electronics modules enables the coach to obtain this information. A separate mobile device, display etc. is not required. Advantageously, the present disclosure enables many users to be monitored at the same time in an easy and intuitive way.

This approach is generally more user friendly than the using a separate mobile device and enables more users to be monitored at the same time. This is because mobile devices are only generally able to connect to a small number of devices over communication protocols such as Bluetooth Bluetooth is generally limited to 8 peripherals normally and most mobile phones only permit up to 5 connections. Moreover, the aspects of the present disclosure enable a user to monitor their own performance without the user of a separate mobile device. The user may look down at their garment to view the emitted light or observe themselves in a mirror.

Referring to Figure 5, there is shown a schematic diagram of another example electronics module 100. The electronics module 100 comprises the processor 101, the light source 103 and the input unit 111 of Figures 2 and 3. This example electronics module 100 additionally comprises a power source 105, a communicator 107, and an interface 109. The electronics module 100 of the present disclosure are not limited to this particular construction and may not comprise all of these components. In addition, the electronics module 100 may comprise alternative or additional components.

The power source 105 is coupled to the processor 101 and is arranged to supply power to the processor 101. The power source 105 may comprise a plurality of power sources. The power source 105 may be a battery. The battery may be a rechargeable battery. The battery may be a rechargeable battery adapted to be charged wirelessly such as by inductive charging. The power source 105 may comprise an energy harvesting device. The energy harvesting device may be configured to generate electric power signals in response to kinetic events such as kinetic events performed by a wearer of the garment. The kinetic event could include walking, running, exercising or respiration of the wearer. The energy harvesting material may comprise a piezoelectric material which generates electricity in response to mechanical deformation of the converter. The energy harvesting device may harvest energy from body heat of a wearer of the garment.

The energy harvesting device may be a thermoelectric energy harvesting device. The power source may be a super capacitor, or an energy cell.

The communicator 107 may be a mobile/cellular communicator operable to communicate the data wirelessly via one or more base stations. The communicator 107 may provide wireless communication capabilities for the garment and enables the garment to communicate via one or more wireless communication protocols such as used for communication over a wireless wide area network (AN), a wireless metroarea network (VVMAN), a wireless local area network (VVLAN), a wireless personal area network (WPAN), Bluetooth (E) Low Energy, Bluetooth i:E) Mesh, Bluetooth 5, Thread, Zigbee, IEEE 802.15.4, Ant, a near field communication (NFC), a Global Navigation Satellite System (GNSS), a cellular communication network, or any other electromagnetic RF communication protocol. The cellular communication network may be a fourth generation (4G) LTE, LTE Advanced (LTE-A), LTE Cat-M1, LTE Cat-M2, NB-loT, fifth generation (5G), sixth generation (6G), and/or any other present or future developed cellular wireless network. A plurality of communicators may be provided for communicating over a combination of different communication protocols.

The electronics module 100 may comprise a Universal Integrated Circuit Card (UICC) that enables the electronics module 100to access services provided by a mobile network operator (MNO) or virtual mobile network operator (VMNO). The UICC may include at least a read-only memory (ROM) configured to store an MNONMNO profile that the wearable article can utilize to register and interact with an MNONMNO.

The UICC may be in the form of a Subscriber Identity Module (SIM) card. The electronics module 100 may have a receiving section arranged to receive the SIM card. In other examples, the UICC is embedded directly into a controller of the electronics module 100. That is, the UICC may be an electronic/embedded UICC (eUICC). A eUICC is beneficial as it removes the need to store a number of MNO profiles, i.e. electronic Subscriber Identity Modules (eSIMs). Moreover, eSIMs can be remotely provisioned to electronics modules 100. The electronics modules 100 may comprise a secure element that represents an embedded Universal Integrated Circuit Card (eUICC).

The interface 109 is arranged to communicatively couple with a sensing component of the garment 200 (Figure 1) so as to receive a signal from the sensing component. The processor 101 is communicatively coupled to the interface 109 and is arranged to receive the signals from the interface 109.The interface 109 may form a conductive coupling or a wireless (e.g. inductive) communication coupling with the electronics components of the garment 200.

The electronics module 100 is mounted on a garment 200 (Figure 1) and conductively connected to sensing components such as electrodes of the garment via electrically conductive pathways of the garment 200. In a particular example, the sensing components are electrodes used to measure electro potential signals such as electrocardiogram (ECG) signals.

The processor 101 may be a component of a controller such as a microcontroller. The controller may have an integral communicator such as a Bluetooth (E) antenna. The controller may have an internal memory and may also be communicatively connected to an external memory of the electronics module such as a NAND Flash memory. The memory is used to for the storage of data when no wireless connection is available between the electronics module 100 a mobile device 300 (Figure 1). The memory may have a storage capacity of at least 1GB and preferably at least 2 GB. The processor 101 is connected to an interface 109 via an analog-to-digital converter (ADC) fronted end and an electrostatic discharge (ESD) protection circuit. The ADC fronted end converts the raw analog signal received from sensing components of the garment into a digital signal. The ADC frontend may also perform filtering operations on the received signals.

Referring to Figure 6, there is shown an example garment 200 according to aspects of the present disclosure. The garment 200 comprises an electronics module holder 203 provided on an outside surface 201 of the garment 200. The electronics module holder 203 is arranged to hold the electronics module according to aspects of the present disclosure. A visual symbol 205 is provided on the outside surface of the electronics module holder 203.

Referring to Figure 7, there is shown a sectional view of a garment 200 comprising an electronics module 100 disposed within the electronics module holder 203 of the garment 200. A terminal region 209 is provided on the inside surface of the garment 200. The terminal region 209 connects to sensing components of the garment 200 via one or more electrically conductive pathways.

The electronics module holder 203 in this example is a pocket 203 provided on the outside surface of the garment 200. The electronics module holder 203 comprises a layer of material 203 which is bonded, stitched, otherwise attached to or integrally formed with the garment 200. The electronics module holder 203 has an inner surface 211 facing the electronics module 100. The electronics module holder 203 has an outer surface 213 which can be considered as part of the outer surface 201, 213 of the garment 200.

The garment 200 is constructed such that light emitted by the light source 103 of the electronics module 100 is visible from the outside surface of the garment 200. In this example, the garment 200 comprises an opening 207 provided in the layer of material 203 of the electronics module holder 203. The opening 207 extends from the inner surface 211 to the outer surface 213. The opening 207 is positioned such that, when the electronics module 100 is provided in the electronics module holder 203, the light source 103 is aligned with the opening 207. The opening 207 may be formed by removing material from the layer of material 203 of the electronics module holder 203 or the layer of material 203 may be formed to include the opening 206 during manufacture.

Rather than providing an opening 207 in the material of the garment 200, a window may instead be provided. The window may be constructed from a transparent, translucent, or light diffracting material. The use of a light diffracting material may provide a light pipe effect to help the light source 103 appear bigger than they are. In other examples, the material of the electronics module holder 203 may have an open-cell construction in the vicinity of the light source 103, when positioned in the electronics module holder 203, such that the light source 103 is visible from the outside of the garment 200.

A visual marker 205 is provided on the outside surface 213 of the electronics module holder 203. The visual marker 205 is constructed in this example to take into account the presence of the opening 207.

Referring to Figure 8, there is shown an example outer layer 203 of electronics module holder 203 in Figure 7. The outer layer 203 is bonded, stitched, or otherwise attached to the garment 200. The outer layer 203 may also be integrally formed with the garment 200. Figure 8 shows the inner surface 211 of the outer layer 203. The inner surface 211 is provided with a surface 215 which increases friction between the inner surface 211 and the electronics module 100 when positioned in the electronics module holder 203. The surface 215 comprises a number (six in this example) of horizontal lines of gripping material provided on the inner surface 211. The gripping material is a silicone-based coating. The surface 215 helps reduce unnecessary rotational or translational movement of the electronics module 100 when positioned in the electronics module holder 203 and helps maintain the interface 109 (Figure 7) of the electronics module 100 in contact with the terminal region 209.

Referring to Figure 9, there is shown another example of the inner surface 211 of the electronics module holder 203. In this example, the surface 215 comprises a number of dots of gripping material provided on the inner surface 211. The gripping material is a silicone-based coating.

It will be appreciated that Figures Band 9 are only two examples of surfaces 215 used to increase friction between the electronics module holder 203 and the electronics module 100. In other examples, the electronics module holder 203 may be separately or additionally elasticised to help hold the electronics module 100 in place. Additionally or separately, the electronics module 100 may be provided with a surface which increases friction between the garment 200 and the electronics module 100 so as to limit motion of the electronics module 100 relative to the garment 200. The surface of the electronics module 100 may comprises a rubberised grip texture, for example.

Referring to Figure 10, there is shown another example sectional view of a garment 200 comprising an electronics module 100 disposed within the electronics module holder 203 of the garment 200. The electronics module holder 203 in this example is a pocket 203 provided on the inside surface of the garment 200. The garment 200 is constructed such that light emitted by the light source 103 of the electronics module 100 is visible from the outside surface of the garment 200. In this example, the garment 200 comprises an opening 207 extending through the outside surface 201 of the garment 200. The opening 207 is positioned such that, when the electronics module 100 is provided in the electronics module holder 203, the light source 103 is aligned with the opening 207. A visual marker 205 is provided on the outside surface 201 of the garment 200. The visual marker 205 is constructed in this example to take into account the presence of the opening 207. The other features of the gar,ent may be the same as or similar to those of Figures 7 to 9.

In Figures 6 to 10, the garment 200 comprises a visual maker 205 located on the outside surface of the garment 200. The visual marker 205 is located at a position corresponding to the electronics module holder 203. The visual marker 205 indicates the location of the electronics module 100 when located in the electronics module holder 203.

The visual maker 205 helps a user activate and/or control the operation of the electronics module 100. When positioned in the electronics module holder 203, the electronics module 100 may be concealed or not easily visible or discernible to the user. This will particularly be the case if the garment 200 has a number of padded areas to help conceal the visual appearance of the electronics module 100 when positioned in the electronics module holder 203. Concealing the appearance of the electronics module 100 is desirable so as to make the garment 200 look more visually attractive to the user as well as fell more comfortable to wear.

Beneficially, the visual marker 205 is placed on the exterior face of the garment 200 and is visible to the user. The visual marker 205 is aligned with the electronics module 100 when positioned in the electronics module holder 203. The visual marker 205 therefore indicates the location of the electronics module 100 when located in the electronics module holder 203.

In some example, the electronics module 100 has an input unit 111 (Figure 3) for controlling the operation of the electronics module 100. The input unit 111 may be a tactile button or a motion sensor amongst other examples. The input unit 111 may in particular require an object such as the hand of the user to approach and tap against the electronics module 100 to perform a control operation. This tapping operation may be performed on the outer surface of the garment 200 and sensed through one or more layers of fabric by the input unit 111. The visual marker 205 in accordance with aspects of the present disclosure indicates the location of the input unit 111 such that an object tapping on the garment 200 in the vicinity of the visual marker 205 is detectable by the input unit 111 of the electronics module 100.

Beneficially, the visual marker 205 allows the user to quickly and easily see where to tap the electronics module 100. This makes it easier for the user to control the operation of the electronics module 100 while positioned in the electronics module holder 203.

In some examples, the electronics module 100 may comprise an antenna coil such as a near field communication (NFC) coil which is used to exchange information with a mobile device 300 (Figure 1). This may in particular be for use in tap-to-pair operations so as to pair the electronics module 100 and the mobile device 300 over another communication protocol such as, but not limited, to Bluetooth 8. The visual maker 205 can beneficially additionally or separately indicate the location of the antenna coil. This enables the user to quickly and easily see where to tap their mobile device 300 so as to enable the data exchange to take place.

Referring to Figures 11 to 14, there are shown example outside surfaces 201 of garments 200 with different forms of visual marker 205 with openings 207 incorporated into or provided alongside the visual markers 205. Figures 11 and 12 show visual makers 205 in the form of simple icons that are easily understandable to users. Figures 13 and 14 show visual markers which comprise machine-readable code. The machine-readable code may comprise an identifier or other information that can be read by a machine. For example, the mobile device 300 may read the machine-readable code using a camera of the mobile device 300. This provides added functionality for the garment 200.

In some examples, the visual marker 205 may act as a fiducial marker 205. A fiducial marker 205 is useable as a point of reference for the garment 200 and thus enables the position of the garment 200 and the motion of the garment 200 over time to be monitored simply by capturing images of the garment 200. In this way, the motion of the wearer of the garment 200 is tracked by determining the location of the fiducial marker 205 in the captured image. The fiducial marker 205 may be in the form of a 2D image. The fiducial marker 205 of the present invention is beneficial as it is simple, of low cost and does not negatively affect the comfort of the garment for the wearer. The fiducial marker may be an augmented reality (AR) marker.

In the example of Figure 13, the marker 205 is a Quick-Response (QR) code and comprises a visual symbol in the form of black marks upon white pathways. The black marks represent the characters in the code string. The visual symbol may additionally encode redundant information for error detection, correction, and uniqueness over different rotations of the marker.

In the example of Figure 14, the marker 205 is based on an AR marker 205. The marker 205 comprises a visual symbol in the form of a 6x6 grid of black or white cells which represent 36 binary '0' or '1' symbols. The 36-bit sequence encodes the code string and may additionally encode redundant information tor error detection, correction and uniqueness over the different rotations of the marker.

In both examples, the code string/data string may be retrieved from the marker 205 by processing an image containing the visual symbol. It will be appreciated that known image processing operations such as contour extraction and edge detection will be used to read the symbol from the image.

The visual marker 205 may be integrated into the garment 200. The visual marker 205 may be printed onto or into the garment 200. Any known garment printing technique may be used such as screen printing or inkjet printing. The visual marker 205 may be embroidered onto the garment 200.

The visual maker 205 is not limited to the examples described above.

Referring to Figure 15, there is shown an exploded view of an example electronics module 100 according to aspects of the present disclosure.

The electronics module 100 comprises the processor 101, light source 103, first communicator 107 and input unit 111 provided on a printed circuit board 113. The power source 105 is provided separately and below the printed circuit board 113. A second communicator 115 in the form of an NFC antenna 115 is also provided. The NFC antenna 115 is positioned above the printed circuit board 113 and comprises an aperture 117 such that the NFC antenna 115 does not obscure light emitted by the light source 103. The electronics module 100 further comprises the interface 109. The interface 109 comprises a magnet 113, and two conductive prongs 115, 117.

The components of the electronics module 100 are provided within a housing formed of a top enclosure 125 and a bottom enclosure 127.
