The present invention relates to an indicator device for detecting the presence of another device and alerting a user of the indicator device when the devices are within a predetermined distance of one another. The present invention also relates to a system comprising two or more indicator devices, and a method of use thereof.
In certain environments it may be desired to maintain a minimum, maximum, or predetermined range of separation distance between one person and another person or place. For example, during an epidemic or pandemic, governments or local authorities may mandate that a minimum separation distance should be maintained between persons, sometimes termed “social distancing.” Additionally, in certain working environments, such as hazardous working environments, it may be desired for workers to maintain a minimum separation distance from each other to mitigate the risk of injury. In other applications, it may be desired to track worker positions as it pertains to other workers, to particular machinery or zone, or as within a shop floor, working site, manufacturing facility, or the like.
Known devices, such as mobile or cellular phones, which may be used for tracking location of a person, have a number of drawbacks. For example, mobile phone users may be reluctant to display the phone in a manner that allows others to observe it. For example, if a wearer of the mobile phone receives an alert, such as a personal text message or push notification, this would then be visible to those in close proximity. Likewise, if a phone call was received and answered, it may then be impractical for the mobile phone to be used as an indicator device to alert other users that an exclusion zone has been breached or that predetermined distance has been exceeded. Furthermore, in order to a mobile phone typically requires third party application software to be installed on the device to be able to fulfil the function above, and the received data is then accessible by the application software provider, which may compromise the privacy of the user.
It would be desirable to provide a device for tracking positioning of a person, for determining and indicating when a predetermined distance has been breached or exceeded between two or more people or between a person and one or more places, and, in particular, for indicating that the minimum separation distance between one user and another has been, or is at risk of being breached, that can operate and be displayed continuously, and that is straightforward to use without having to rely predominately on third party devices.
The present inventor has appreciated the shortcomings in known devices for detecting the presence of another user.

The devices 1, 100 may include a non-transitory computer readable medium having stored thereon software instructions that, when executed by a processor, cause the processor to generate the applicable signal to operate the indicator element 8, 108 if the distance between the device 1 and other device 100 is within the predetermined distance.
In an embodiment, and as best shown in
The predetermined distance between the indicator device 1 and the other device 100 may define an exclusion zone, or safe working distance, from the user of the indicator device 1. In this embodiment, the exclusion zone is determined by a sphere having the predetermined distance as its radius.
When the indicator elements 8, 108, are active, the proximity sensor 8, 108, of the indicator device 1 and the other device 100 may be operable to deactivate each indicator element 8, 108 of the opposite device 100, 1 if the devices 1, 100 are moved beyond the predetermined distance (outside of the exclusion zone). This can be done repeatedly and continually, such that the devices 1, 100, can continuously activate and deactivate the indicator elements 8, 108, of the opposite device 100, 1 and the distance between the two devices 1, 100, can be continuously monitored and alerted when the certain criteria or distances are met.
In an embodiment, the proximity sensor 8, 108, of the indicator device 1 and the other device 100 are configured to trigger or activate the indicator element(s) 8, 108, substantially instantaneously in response to the opposite device 2, 100 entering the exclusion zone (or when the predetermined criteria, such as less than the minimum distance, is reached) and to deactivate the indicator element(s) 8, 108, substantially instantaneously in response to the opposite device 1, 100 leaving the exclusion zone (or when the predetermined criteria, such as more than the minimum distance, is reached). In other embodiments, there may be a delay between the devices 1, 100 being within, or outside of, the exclusion zone (i.e., within, or outside of, the predetermined distance) and the subsequent triggering or deactivation of the indicator elements 8, 108. For example, the devices
The indicator device 1 may also be operable to detect the presence of a plurality of other devices (not shown) within the exclusion zone or when a certain predetermined criteria is met, such as minimum or maximum distance, and the indicator device 1 may be configured to trigger each indicator element 8 when at least one of the plurality of other devices is within the exclusion zone or when a certain predetermined criteria is met, such as minimum or maximum distance. The plurality of other devices could be substantially identical devices to the indicator device 1.
The proximity sensor 6 of the indicator device 1 may be configured to communicate only with the proximity sensor 106 of the other device 100, or the other devices (not shown).
In an embodiment, the indicator device 1 is configured to trigger the (or each) indicator element 8 only when a substantially identical indicator device is detected within the exclusion zone and to discard or ignore the presence of any other devices that may be within the exclusion zone. The proximity sensor 6 is configured to operate each indicator element 8 only when an identically programmed device is detected within the exclusion zone. That is, a device programmed to carry out the same functions as the indicator device 1.
In an embodiment, the proximity sensor 6 of the indicator device 1 includes a control module 6a operable to send one or more signals to each indicator element 8 of in the indicator device 1 in response to signals received from the other device 100, which, in turn, also includes a control module 106a operable to send one or more signals to its indicator elements 108 in response to signals received from the indicator device 1. As shown in
In an embodiment, the proximity sensor 6 of the indicator device 1 could include a pairing module 6c operable to pair the proximity sensor 6 of the indicator device 1 with a proximity sensor 106 of the other device 100. The pairing module 6c may be operable to automatically pair the indicator device 1 with another device 100. In this embodiment, the proximity sensor 6 is operable to detect that the indicator device 1 and the other device 100 are within the predetermined distance without requiring that the indicator device 1 and the other device 100 are paired.
In an embodiment, the proximity sensor 6 is configured to be non-responsive to signals received from non-identical devices, or non-identically programmed devices. That is, devices that are not programmed to carry out the same functions as the indicator device 1. The proximity sensor 6 is operable to maintain the indicator elements 8 as inactive when substantially non-identical devices are present within the exclusion zone, and when no identical other devices 100 are within the exclusion zone. The proximity sensor is configured to operate the indicator elements 8 when an identical, other device 100, is within the exclusion zone regardless of when or if a non-identical device is also within the exclusion zone. It is also noted, however, that the proximity sensor may be configured to operate the indicator elements 8 when a non-identical device is within the exclusion zone regardless of whether or not an identical, other device 100, is within the exclusion zone.
The proximity sensor 6 includes a device selection module 6d operable to differentiate between other devices that should ignored or be unnoticed and other devices 100 whose presence should be detected, and the proximity sensor 6 is operable to trigger the indicator elements 8 by using the device selection module 6d to identify only the other devices 100 that should be responded to or that should prompt an alert notice to the user.
The proximity sensor 6 is configured to be non-responsive to signals received from a mobile or cellular phone, or the like, and to maintain the indicator elements 8 as inactive when a mobile or cellular phone, or the like, is within the exclusion zone (or within a predetermined distance) and when no other devices for alerting are within the exclusion zone (or within a predetermined distance). The device selection module 6d is operable to filter out and exclude data received from mobile or cellular phones, and other similar devices like radios, intercoms, pagers, and the like.
In the embodiment illustrated and described here, the indicator device 1, specifically the housing 2 thereof, is a tag. However, it should be appreciated that the indicator device 1 and optionally the housing 2 thereof could be a card security device, security tag, badge, marker, identification device or identification card, identification tag, a status identification device, a wearable device (either a disposable or non-disposable) such as a wristband, bracelet, necklace, pin, mechanical or adhesive attachable device and/or other similar type device. Furthermore, in some embodiments, the indicator device 1 could be configurable to include an authentication element, such that the indicator device can be used with an authentication element reader to regulate access to a secure or restricted area. The authentication element may be a barcode, a near field communication device, a photograph, indicia, a graphic, an image, text, a code, numbers, or any combination thereof, or the like.
As shown in
The indicator device 1 may be operable to receive data from the other device 100, or any other device, and to discard all of the received data from the other device 100, or any other device (i.e. no received data is stored). In an embodiment, the indicator device 1 is configured to discard all data associated with the use thereof (user data). That is, the indicator device 1 is configured to not store any data obtained or inferred from the user of the indicator device 1, such as location data, or data concerning the activation and deactivation of the indicator device 1. In this arrangement, no user data is stored by the indicator device 1. Therefore, the present invention is thought to be advantageous over other devices, as no user data or received data is stored by the indicator device 1, and thus the privacy of the user thereof is maintained.
The indicator device 1 can also be configured to be adaptable to store any data or information, and can be capable of storing any data (e.g. regarding the historic location of the indicator device and/or the other device(s), or relating to the activation or deactivation of the indicator device 1).
In one embodiment the indicator device 1 lacks a data storage device or component, or ability (e.g. cloud connections). The capacity of the indicator device 1 to store user data and received data is 0 Bytes. That is, the indicator device 1 is devoid of a memory element for storing data received from another device 100, or data associated with the use of the indicator device. Furthermore, the indicator device 1 is configured such that a data storage device cannot be communicatively or physically connected therewith (i.e., a data storage device cannot be connected to the device, such that received data or user data cannot be stored).
In one embodiment the indicator device 1 contains a storage device. The storage device can be a memory chip or similar device, or it may include the ability to transmit data to a server or cloud storage. The storage device can be configured to store some or all of the received data or user data. The storage device can be configured to permanently store received data or user data. The storage device can be configured to temporarily store received data or user data, i.e., 24 hours, 7 days, 30 days, 60 days, 90 days, etc. The data can be accessed and analysed to determine if the user violated the applicable exclusion zone during any predetermined time. This information can be used to determine compliance with any requirements or regulations to maintain an appropriate distance from others. This information may also be used for other purposes, including tracking a worker's working hours and position, HR complaints, worker's compensation claims, other liability, etc.
It is thought to be advantageous that the indicator device 1 of the present invention may be operable to automatically detect the presence of the other device 100, and to automatically trigger each indicator element 8. In this arrangement, the indicator device 1 is a hands-free device. That is, the indicator device is a hands-free device when switched on. The indicator device may include a clip or lanyard to facilitate wearing or the device on a body of a user, or the indicator device may be sized and shaped to as to fit in a user's pocket, uniform, or working attire. In an embodiment, the indicator device may be sized and shaped as a card, such as a badge, identification card, or the like. For example, the indicator device may have the approximate length and width of a card, and may have a depth or thickness that is sized to fit the components therein. In an embodiment, badge or identification information may also be integrated onto the indicator device so that the indicator device may also serve as a badge or identification card and vice versa.
In an embodiment, the indicator elements 8 include an audio indicator element 8a (a buzzer or beeping system, as examples of an audible device) and a visual indicator element 8b (such as a red LED). The visual indicator element 8b may include a label or text for displaying the meaning of the visual indicator element 8b to the user of the other device 100. It is noted that the indicator device may include one or more auditory indicators, one or more visual indicators, and/or one or more tactile or haptic indicators. For example, the indicator may include only a single auditory indicator, such as a buzzer or beeping system. The indicator device may include a progressive or gradual auditory indicator or system, such as softer and slower beeps for when a user or other device is near breaching an exclusion zone or entering a predetermined distance, louder and faster beeps for when a user or other device has just breached or is at the approximate “edge” of an exclusion zone or predetermined distance, and very loud and non-stop beeping for when a user or other device has fully breached an exclusion zone or entered a predetermined distance. The gradual auditory indicator or alerting system may be based on different thresholds of distance and/or based on how much time a user has been within a certain predetermined distance or zone. It is also noted that instead of the auditory indicator, the indictor may include a visual indicator or system such as a series of more than one light, different color lights, different brightness of the lights, etc., to signify different alerts to the user. Similarly, the indicator may include a tactile indicator or system, such as a vibration, that has a different vibration pattern or intensity of vibration to signify different alerts to the user.
In an embodiment, all of the components of the indicator device 1 are located within the housing 2.
In the embodiment illustrated and described here, the predetermined distance is approximately 2 meters. It will be appreciated that the indicator device 1 could be designed to work with another predetermined distance (such as one meter).
The range of the indicator device may be determined by a sphere having the predetermined distance as its radius, and the radius approximately 2 meters. However, the proximity sensor 6 of the indicator device 1 could be arranged or configured to have a different type of range (e.g. aspherical). The range of the indicator may also be determined as a dome having the predetermined distance as its radius (i.e. no downward measurement). The range of the indicator may also be determined horizontally from the user (i.e. no vertical measurement), and the like.
The proximity sensor 6 may include a transceiver element 6e (i.e. a transmitter and a receiver element), operable to wirelessly detect the presence of the other device 100 using Bluetooth (an example of a wireless communication protocol). It will be appreciated that other wireless communication protocols could be used, such as cellular, Bluetooth LE, UWB, Wi-Fi, Zigbee or a combination thereof. One embodiment includes a UWB component to position, detect, measure, and collect signals from other indicator devices and may also be used to store data generated from these signals in a storage device contained within the indicator device. A BLE or Wi-Fi component may send the data to a separate device such as a cell phone, computer or other similar device where the data is processed into a user defined output or may send the data to a cloud server or other storage device. The device may include a non-transitory computer readable medium having stored thereon software instructions that, when executed by a processor, cause the processor to generate the applicable data.
In one embodiment, the proximity sensor utilizes UWB in combination with an antenna system to increase the UWB's range and reception reliability. The antenna system can be a ceramic antenna system. The UWB proximity sensor positions, detects, measures, and collects data from other indicator devices. The UWB, in operation, sends signals from approximately every 2 nano-seconds (ns) up to hundredths of milli-seconds (ms) to achieve real time accuracy. In one embodiment, the UWB sends a signal to search for other devices approximately every 150 ms. In one embodiment, the UWB can use Time of Flight (ToF) to measure the distance between a UWB proximity sensor in one device and a UWB proximity sensor in another device. In one embodiment, the data collected is transmitted to a separate receiving device such as a cell phone, computer or other device that is capable of receiving such data, or is sent to a cloud server or other storage device. The data can be communicated to the separate receiving device by BLE, Wi-Fi or Bluetooth. The data may be communicated directly to the separate receiving device with or without storage on the indicator device.
The proximity sensor 6 of the indicator device 1 may be configured to only be responsive to proximity sensors 106 comprising the same type of transceiver element 6e and wireless communication protocol (i.e. Bluetooth or UWB) as the proximity sensor 6 of the indicator device 1.
The control module 6a may be operable to receive data from the transceiver element 6e and to provide signals to the indicator elements 8. In an embodiment, the proximity sensor 6 comprises a single transceiver element 6e and a single control module 6a. The present invention therefore may include significantly fewer components or electronic circuitry than more complex devices, such as mobile phones.
The proximity sensor 6 may be configured to operate within a frequency band, or frequency bands, of the RF spectrum. In an embodiment, the proximity sensor is configured to operate within a frequency band having a frequency range of between approximately 2.4 GHZ to 2.4835 GHz. The frequency band or bands may be located at a different region of the RF spectrum to the mobile phone, or cellular phone, network bands. In one embodiment the proximity sensor may be configured to operate within a frequency band having a frequency range of between approximately 3.1 GHZ to 10.6 GHz.
In an embodiment, the indicator device 1 is a lightweight device and weighs approximately 50 grams.
The indicator device 1 may be a substantially planar device, and has a thickness of approximately 7 mm, a length of approximately 85 mm, and a width of between approximately 55 mm. As described here, the indicator device may generally be sized and shaped as a card, badge, or identification card.
In an embodiment, the cuboidal housing 2 comprises substantially planar surfaces and is a substantially planar member.
The housing 2 may comprise a hole/aperture 2a (an example of an attachment member receiving portion), configured to receive one or more user attachment members configured to attach the housing 2 to an object. The user attachment members or object could be a lanyard, a belt, a clip, a hook, a key ring, webbing, string, rope, and/or a chain.
In an embodiment, the indicator device 1 is configured to be wearable, and can be worn, in use, around a user's neck with, for example, a lanyard, such that the indicator device 1 is arranged substantially around the chest area of the user. The indicator device 1 may also be attached to a user's shirt, by for example, a clip, a user's belt, a user's keychain, and the like.
In an embodiment, the indicator elements 8 are arranged in and/or on the housing 2 such that they are visible and/or audible by any user within the exclusion zone, or in proximity to the exclusion zone and by the user of the indicator device 1.
The indicator device 1 may comprise a switch 12 (an example control element) operable to activate and deactivate the indicator device 1 (i.e. to turn it on and off). In an embodiment, the switch is configured to deactivate the indicator elements 8 temporarily or for a set period of time, for example approximately 1 minute, 5 minutes, 10 minutes, etc. In this arrangement, the indicator device 1 can be deactivated to allow the user to approach a user of the other device 100 and then will reactivate automatically after the set amount of time and alert the user if the user is still in the exclusion zone of another device 100. For example, it may be advantageous to allow two workers or users minimal time within the same zone or near one another. Additionally, the switch may instead be used to deactivate the device for a longer period of time, for example, 1, 2, 3, 4, 8 hours or until the switch is activated again. For example, members of the same household may not be required to comply with social distancing, and therefore it may be advantageous to allow for the indicator device 1 to be deactivated if for example, both members of the same household are outside of the home and wish to exchange an object. It will be understood that in this scenario, when in the home, the indicator device 1 would not be used and would thus be deactivated, until the user ventured outside again.
In an embodiment, the switch 12 is a push button, and the indicator device 1 is deactivated by pressing the switch once. It will be appreciated that other types of control element could be used, such as another type of switch, including a push switch, a turn knob, or the like.
In an embodiment, the power supply 4 is a coin cell battery, including an amber LED (an example power supply status indicator element, not shown). In an embodiment, the power supply 4 may be a rechargeable battery.
The indicator device 1 may be configured to have an operation time of at least 2 weeks. In this arrangement, the indicator device 1 can be continuously used for 2 weeks or more without replacing or recharging the power supply, which is thought to be advantageous over devices that must be recharged more frequently, particularly as it may be essential during a pandemic or epidemic, or in a hazardous work environment, that a safe distance between persons is maintained.
The housing 2 may be compatible with one or more printing techniques, such as inkjet printing, screen printing, digital printing, or combination of digital and screen printing, which allows the housing to be customised to display information about the wearer thereof and the predetermined distance. The housing 2 could be customised by including one or more graphics, including branding (late customisation of the indicator device 1).
The housing 2 comprises two major planar surfaces 2b, each major planar being compatible with one or more printing techniques.
The housing 2 may include an antimicrobial agent located on at least a portion of one or more surfaces of the housing 2.
In an embodiment, the housing 2 is made from acrylonitrile butadiene styrene. In an embodiment, the housing 2 is manufactured using an injection moulding process. Other manufacturing techniques could be used.
The power supply 4, the indicator elements 8 and the proximity sensor 6 may be located on the same printed circuit board (PCB) 16, which is accommodated by the housing 2 therein.
In an embodiment, the housing 2 includes a light transmissive element 2c, which may be a substantially optically transparent member located on one or two planar surfaces of the housing 2, and may be arranged to be backlit by the visual indicator element 8b.
In an embodiment, at least a portion of the light transmissive element 2c is located on a major surface 2b of the housing 2 and at least a portion of the light transmissive element 2c is located on an upper minor surface 2d of the housing 2. In this arrangement, the wearer or user of the indicator device 1 can observe at least one of the visual indicator elements 8 by looking down onto the indicator device 1.
As shown in
The housing 202 of the device 200 shown in
The indicator element 208, or elements, in a device 200 as depicted in
The visual indicator element(s) may include a label, text, graphic, photograph, numbers, or the like, for displaying the meaning of the visual indicator element(s) to the user of the other device 10, 100, 300.
The power supply 204 of a device 200 as shown in
An indicator element 208 may be located within the housing 202. One or more indicator element(s) may be located within the housing 202 and one or more of the indicator element(s) 208 may be located outside of the housing 202. All of the components of the indicator device 200, 300 may be located within the housing 202, 302 thereof.
In an embodiment, one or more indicator devices 10, 100, 200, 300 may transmit location data to a server. For example, the location data may be superimposed on a map of a facility or workplace and show indicators for the location of each worker or user. The map with locations may be updated in real time or after a set period of time.
In an embodiment, the indicator device that is a wearable 10, 100 may be incorporated into a watch device (for example as described in regard to
In addition to allowing access to an area, the indicator device may be utilized to ensure that a group of people, such as a family or school class are always within a predefined distance with one another. This would prevent one of the children/people from wandering off and potentially getting lost. An example, would be that each member of the group has a wristband with the indicator device. The wristband may be put on outside of the facility to which the group is accessing. The wristband may allow entrance to the facility. In addition, if any one of the group is more than a predetermined distance from anyone else within the group, the leader or parents may receive an alert on a device, such as a smartphone, or on their wristband with indicator device as described above. The person from the group that has exceeded the predetermined distance may also receive an alert. The indicator device may also include a proximity sensor that may be manually activated. In this case, if one of the wearers has wondered beyond the predetermined distance, is warned, he or she may activate the proximity sensor. The proximity sensor may provide a notification to the wearer as she gets closer or further to one of the others in the group or just the leader/parent. This could prevent children or others from getting lost in large venues such as theme parks and concerts. Of course, while a wristband is described herein, the indicator device could take on any of a number of different forms such as any kind of wearable device (e.g., ring, necklace, anklet, armband, headband, hat, clip for a shoe, etc. In addition, the indicator device could be a tag attached to a lanyard or any other similar device or mechanism.
Modifications may be made to the present invention without departing from the scope of the invention.
For example, whilst the indicator device 1 illustrated and described here provides an alert to the user thereof, in other embodiments, the indicator device could be configured to initiate an alert. That is, the indicator device 1 itself may not alert the user. In this arrangement, the indicator device 1 could be attached to an object, and the other device 100 could be attached to a user or another object, and the indictor device 1 could be operable to initiate an alert that the user or object has moved within a predetermined distance of the indicator device 1.
Although the embodiments of the present invention have been illustrated in the accompanying drawings and described in the foregoing detailed description, it is to be understood that the present invention is not to be limited to just the embodiments disclosed, but that the invention described herein is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the claims hereafter. The claims as follows are intended to include all modifications and alterations insofar as they come within the scope of the claims or the equivalent thereof.
