TECHNICAL FIELD

The technology disclosed relates to methods, a sensor device, a communication node and a system.

In aspects, the technology disclosed relates to methods, a sensor device, a communication node and/or a system for determining which mobile communication device, and associated user, is currently closest to a sensor device at least partly based on a determined signal strength of a broadcast signal sent from the sensor device and which is received by at least one mobile communication device, or at least partly based on a distance measurement determined by means of phase.

In certain aspects, the technology disclosed relates to methods, a sensor device, a

communication node and/or a system for determining which user activated an input means of a sensor device based on a determined signal strength of a broadcast signal sent from the sensor device and which is received by at least one mobile communication device, including the mobile communication device of the user who activated the input device.

In certain aspects, the technology disclosed relates to methods, a sensor device, a

communication node and a system for alerting a user of a mobile communication device determined to be closest to the sensor device that the sensor device has obtained a pre-defined threshold value by at least one of continuously measuring, detecting and recording. The determination of which mobile communication device is closest to the sensor device may then be at least partly based on the determination of a signal strength of a broadcast signal sent from the sensor device or at least partly based on a distance measurement determined by means of phase using a plurality of received broadcast signals/messages having different frequencies.

The technology disclosed relates to methods, a sensor device, a communication node and a system configured to allow for a simple way to obtain information associated with a sensor device, and/or provide information to the user of a mobile communication device in response to a trigger event such as the activation of input means of the sensor device or obtaining a pre- defined threshold value by at least one of continuously measuring, detecting and recording by the sensor device. The information provided may be related to a product or activity associated with the sensor device or may be information associated with the sensor device obtaining a pre defined threshold value.

According to certain aspects of the technology disclosed, a broadcast signal, or a sequence of broadcast signals, is transmitted from a sensor device, via short-range wireless communication in response to a trigger event sensed by the sensor device. The broadcast signal may then include a unique identifier of the sensor device and the trigger event may be any of activating an input means of the sensor device, e.g. pushing a button in the sensor device by a person, or that a sensor or detector of the sensor device obtaining a pre-defined threshold value by at least one of continuously measuring, detecting and recording.

BACKGROUND

The sensor devices known in the art may be configured to periodically sending broadcast messages to nearby user devices.

Bluetooth based push buttons known in the art are often supposed to be connected to something, e.g. a phone or a hub, in order to operate. In some applications, each button may then be unique depending on how the application program in the phone is configured and/or the hub of the system is configured. Different things may happen when the user pushes different buttons.

In certain aspects, this disclosure also relates to trigger-event based response execution.

PROBLEMS WITH THE PRIOR ART Beacons, e.g. iBeacons, known in the art continuously transmit messages that can be read by phones and application programs. Geofencing methods include method for estimating a distance between mobile phones and each of a plurality of beacon nodes based on a received signal strength indicator of the received beacon signals. However, beacons do not typically judge which user or phone is closest to a beacon and they are not generally triggered but are rather configured for continuously transmitting. US9733808B2 describes a sensor device thatupon a trigger sends its unique device ID to a server, which decides what happens based on the device ID. The message that the sensor device sends only contains the device ID.

Proximity sensors, e.g. disclosed in US20140073262A1, may trigger alarms based on the sensors signal strength, but these sensors are always connected to a phone.

Common smart button solutions may be enough when there is only one user of a button or when a button is configured to control a third device such as a connected light bulb. When the button is pushed, the button informs so to whichever device it is connected to, but the system doesn’t know who pushed the button or which mobile communication device is closest to the button.

Certain aspects of the present disclosure advantageously alleviate the problems described above by introducing a solution that allows a simple way for interacting with mobile

telecommunications related services in response to trigger events such as a button press or when a sensor or detector of the sensor device obtains a pre-defined threshold value.

DETAILED DESCRIPTION

In the drawings, similar details are denoted with the same reference number throughout the different embodiments. It is to be understood that the aspects and embodiments of the present disclosure described above may be used in any combination with each other. Several of the aspects and embodiments may be combined together to form a further embodiment of the present disclosure. A system, a method, a sensor device, or a communication node which is an aspect of the present disclosure may comprise at least one of the embodiments of the present disclosure described above.

A sensor device is herein defined as a device comprising at least one of an input means (e.g. a button], a temperature sensor, an accelerometer, a motion sensor, a gyro, a microphone, a potentiometer, a pressure sensor and a sensor for measuring the concentration of particles in media. The sensor device according to the technology disclosed comprises input means such as a touch-sensitive button and/or may be configured to at least one of measuring, detecting or recording at least one parameter related to at least one of temperature, pressure, luminance, particles in medium, movement and acceleration.

In wireless communications, particularly in radio frequency, signal strength (also referred to as field strength] refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m] For very low-power systems, such as mobile phones, signal strength is usually expressed in dB-microvolts per metre (dBpV/m] or in decibels above a reference level of one milliwatt (dBm] In broadcasting terminology, 1 mV/m is 1000 pV/m or 60 dBp (often written dBu]

In embodiments of the technology disclosed, distance measurements by means of phase which are performed by the mobile communication devices are used for determining which mobile communication device is closest to the sensor device.

In certain embodiments, a distance measurement by means of phase is used in a scheme to locate a transmitter. The system typically consists of three antennas. There is a transmitter in the sensor device, that in a sense acts as a target, in terms of radar concepts. Two receivers in the mobile communication device are used to determine the distance needed to find the position of the transmitter, i.e. the position of the sensor device.

A simpler way to measure distance according to certain embodiments of the technology disclosed is to calculate the phase shift between the received signal and the transmitted signal. The set-up considered here is not a typical radar since the target is replaced by a transmitter. In wave motion, the phase increases in the direction of propagation. Phase shifts are often measured in degrees. Frequency and phase evaluation results are combined to reach the aspired accuracy in the m range. Consequently, after the coarse detection using the frequency a correction of the estimated position is accomplished by the evaluated phase information within the unambiguous range. The important entity is the phase difference between the reference and the received wave/signal. In certain embodiments, the phase method may to some degree be combined with a Frequency-Modulated Continuous Wave (FMCW] measurement

FMCW radar (Frequency-Modulated Continuous Wave radar = FMCW radar] is a special type of radar sensor which radiates continuous transmission power like a simple continuous wave radar (CW-Radar] In contrast to this CW radar FMCW radar can change its operating frequency during the measurement: that is, the transmission signal is modulated in frequency (or in phase]. Possibilities of Radar measurements through runtime measurements are only technically possible with these changes in the frequency (or phase].

Simple continuous wave radar devices without frequency modulation have the disadvantage that it cannot determine target range because it lacks the timing mark necessary to allow the system to time accurately the transmit and receive cycle and to convert this into range. Such a time reference for measuring the distance of stationary objects but can be generated using of frequency modulation of the transmitted signal. In this method, a signal is transmitted, which increases or decreases in the frequency periodically. When an echo signal is received, that change of frequency gets a delay At (by runtime shift] like to as the pulse radar technique. In pulse radar, however, the runtime must be measured directly. In FMCW radar are measured the differences in phase or frequency between the actually transmitted and the received signal instead.

The basic features of FMCW radar are:

• Ability to measure very small ranges to the target (the minimal measured range is comparable to the transmitted wavelength];

• Ability to measure simultaneously the target range and its relative velocity;

• Very high accuracy of range measurement;

• Signal processing after mixing is performed at a low frequency range, considerably simplifying the realization of the processing circuits;

• Safety from the absence of the pulse radiation with a high peak power.

Characteristics of FMCW radar are:

• The distance measurement is accomplished by comparing the frequency of the received signal to a reference (usually directly the transmission signal]. • The duration of the transmitted waveform T is substantially greater than the required receiving time for the installed distance measuring range.

In embodiments of the technology disclosed using distance measurements by means of phase to determine which mobile communication device is closest to the sensor device, the hardware typically consists of three antennas, one for transmission and two for the reception. A transmitting antenna can be viewed as a device that converts a guided electromagnetic wave on a transmission line into a spherical wave propagation in free space. In certain embodiments, the reception antennas may be controlled with a relay since two measurements are needed. The distances between the reception antennas and the transmitting antenna are measured.

The short-range wireless broadcast signal/message transmitted by the sensor device according to the technology disclosed may, for example, be a Bluetooth signal/message, a Zigbee signal/message, or any other suitable protocol with a broadcast function for transmitting short- range wireless broadcast signals/messages/advertisements.

In certain embodiments of the technology disclosed, the sensor device is configured transmit a short-range wireless broadcast signal/message in the form of a Bluetooth broadcast signal/message and mobile communication devices are configured to receive the Bluetooth broadcast signal from the sensor device.

In certain embodiments of the technology disclosed, the sensor device is configured transmit a short-range wireless broadcast signal/message in the form of a Zigbee broadcast

signal/message and mobile communication devices are configured to receive the Zigbee broadcast signal from the sensor device.

Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, Zigbee is a low-power, low data rate, and close proximity (i.e., personal area] wireless ad hoc network.

The technology defined by the Zigbee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs], such as Bluetooth or more general wireless networking such as Wi-Fi. Applications include wireless light switches, home energy monitors, traffic management systems, and other consumer and industrial equipment that requires short-range low-rate wireless data transfer. Its low power consumption limits transmission distances to 10-100 meters line-of-sight, depending on power output and environmental characteristics. Zigbee devices can transmit data over long distances by passing data through a mesh network of intermediate devices to reach more distant ones. Zigbee is typically used in low data rate applications that require long battery life and secure networking (Zigbee networks are secured by 128 bit symmetric encryption keys.] Zigbee has a defined rate of 250 kbit/s, best suited for intermittent data transmissions from a sensor or input device.

Bluetooth is a short-range wireless technology standard that allows data to be exchanged between fixed and mobile devices. The technology uses short wavelength radio waves from 2.4 to 2.485 GHz. Unlike other forms of connectivity such as wi-fi or 4G, Bluetooth carries connections between devices and other devices as opposed to carrying data to and from the internet. BLE stands for Bluetooth Low Energy and is a form of wireless communication designed especially for short-range communication. BLE is very similar to Wi-Fi in the sense that it allows devices to communicate with each other. BLE is designed for situations where battery life is preferred over high data transfer speeds.

Bluetooth sensor devices are hardware transmitter - a class of Bluetooth Low Energy (BLE] devices that broadcast their identifier to nearby portable electronic devices.

Bluetooth sensor devices may use BLE proximity sensing to transmit a universally unique identifier which is picked up by a compatible mobile application (APP] or operating system of a mobile communication device. The identifier and several bytes sent with it can be used to determine the device's physical location, track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification. The frequency of iBeacon transmissions depends on the configuration of the sensor device and can be altered using device specific methods.
