In recent years, mobile phones became a constant companion of people in private life but also at the work place. Mobile phones have long since extended their application from being a mere messenger device via telephone, instant messenger applications or e-mail applications, to a control centre for a large variety of devices such as smart home appliances, fitness and sleep tracker variables, mobility systems, such as electric bikes, electric scooters or electric cars. The success of the mobile phone stems from the fact that nowadays, a mobile phone is essentially a general purpose computer which can run an enormous variety of specialized software applications (apps) and which is already equipped with a variety of wireless communication means, such as cellular network connectivity, WLAN connectivity or Bluetooth connectivity.

The technical problem underlying the present invention is to provide a protective personal garment, especially a protective jacket, which can make use of the versatility of modern day mobile phones in order to increase the protective functionality of the garment and/or assist the wearer in accomplishing designated tasks.

This technical problem is solved by the protective personal garment as defined in appended claim 1 . Preferred embodiments of the protective personal garment of the invention are subject of the dependent claims.

Accordingly, the present invention concerns a protective personal garment comprising a torso portion having an inner face and an outer face, said torso portion being provided with a collar, a left arm sleeve and a right arm sleeve extending from said torso portion, said left arm sleeve and said right arm sleeve having respective inner faces and outer faces. According to the invention, the protective personal garment comprises at least a first micro-controller configured to establish a data communication with a control unit, said first micro-controller being provided with one or more electrical connectors to connect said first micro-controller with one or more sources of electrical energy. Further, the protective personal garment is equipped with one or more functional units which are electrically connected with the first micro-controller.

The present invention suggests to allow a protective personal garment, such as a safety jacket, to communicate with a control unit in order to exchange data with functional units of the protective personal garment via a micro-controller of this garment.

A “control unit” in the sense of the present invention denotes any input means or input/output means, which are suitable to command/control the functional units of the protective personal garment. For instance, press buttons or touch buttons, which are functionally connected to the first micro-controller, can be employed to trigger certain operations of the functional units. A “control unit” in the sense of the present invention can be a single device such as a single board having various control buttons or a distributed device having various control buttons, which are arranged at different places at or in the protective personal garment. Likewise, a “control unit” in the sense of the present invention can be integrated with the personal garment or can be a separate device which can establish a wire-based or wireless communication with the first microcontroller. For instance, in one embodiment, the “control unit” can be configured as a touch panel. In another embodiment, the “control unit” can include a display and can, for instance, be configured as a touch-sensitive display.

Preferably, however, the control unit is a mobile device such as a mobile phone and the protective personal garment is able to communicate with an appliance running on the mobile phone.

A “mobile device” or a “mobile phone” in the sense of the present invention can be any typical, commercially available smartphone which runs a dedicated app for communicating with the micro-controller of the protective personal garment. However, “mobile phone” in the sense of the present invention can also be a dedicated mobile device having the sole purpose of being used in connection with the protective personal garment of the present invention. The term “mobile phone” has therefore to be construed more broadly as encompassing any mobile device which can establish a data communication with the micro-controller of the protective personal garment and which is further connected to a wireless network. This will usually be a cellular network of a mobile phone service provider but it can also be a private WLAN netw"' ¹ ' — — wireless data communication network. Therefore, while in most use ca

4 phone” will also have a telephone capability, such a telephone capability is not necessarily required for the purpose of the present invention.

One of the most important environmental effects of a hard working wearer of a protective personal garment is related to the ambient temperature in the environment which can range from temperatures -20 °C or lower to +50 °C and higher. Therefore, in certain embodiments of the protective personal garment of the present invention, the functional units comprise heating elements which can be arranged at various places of the protective garment. Preferably, heating elements are arranged at the inner face of the torso portion. Additionally or alternatively, heating elements can also be arranged at the inner faces of the left arm sleeve or the right arm sleeve. Again additionally or alternatively, heating elements can be arranged at the inner face of the collar of the torso portion of the protective personal garment. The heating elements are preferably controllable and in one embodiment, the heating elements are resistive heaters which can be controlled via an electrical current passed through the resistive heaters.

Temperature control may also involve cooling the wearer of the protective personal garment. Therefore, in one embodiment of the present invention, the functional units comprise cooling elements arranged at the inner face of the torso portion. Additional cooling elements can also be provided in other areas of the inner faces of the garment.

A variety of different controllable cooling elements can be envisioned. In one embodiment, the cooling elements comprise at least one cooling duct arranged at the inner face of the torso portion and at least one electrical fan arranged at one end of the cooling duct.

Preferably, the protective personal garment comprises both heating elements and cooling elements.

In certain embodiments, the heating elements and/or cooling elements can be actively controlled by the user, for instance using a suitable control feature of the application running on the mobile phone or any other control element of the cont"' ¹ — ¹ suitably configured buttons or control nobs.

Preferably, however, the heating and/or cooling functionality of the protective personal garment is at least partially automatized.

To this effect, in certain embodiments of the present invention, the functional units comprise at least a first environmental sensor arranged at the inner face of the torso portion. The environmental sensor preferably comprises at least a first temperature sensor but can also comprise additional sensors relevant to the wellbeing of the wearer, such as a humidity sensor. Based on the data provided by the first environmental sensor, the heating elements and/or cooling elements can be engaged automatically, without the wearer having to actively engage with the application running on the mobile phone. In certain embodiments, the application running on the mobile phone will still, however, allow the user an active control of the heating elements and/or cooling elements or may even allow to specify certain temperature ranges for the temperature read by the first temperature sensor and, optionally, including data of a first humidity sensor of the first environmental sensor so that heating or cooling will only be activated if the detected temperature leaves the predetermined ranges.

In certain embodiments, the functional units can comprise a second environmental sensor arranged at the outer face of the torso portion thus allowing to detect the ambient environmental sensor as well. Preferably, both a first environmental sensor for the inner temperature and, optionally, the inner humidity near the torso of the wearer and a second environmental sensor for detecting the ambient temperature and, optionally, the ambient humidity will be employed thus allowing a more elaborate control scheme for temperature regulation of the protective personal garment.

In a preferred embodiment, the first environmental sensor comprises a first temperature sensor and a first humidity sensor for measuring the inner temperature and the inner humidity inside the protective garment and the second environmental sensor comprises a second temperature sensor and a second humidity sensor for measuring the inner temperature and the inner humidity inside the protective garment. The control unit receives measurement data of temperature and relative humidity of ^iL '" - ¹ — ¹ external environment of the wearer and a software application controls

M/63092-PCT Technical Connectivity Wear GmbH

6 cooling elements based on the measured data. In the case of cooling, inflow speed or the volume of air conveyed per unit of time can be controlled. The cooling effect is caused by the evaporative cooling of the sweat of the body of the wearer. Thus, with the same inflow rate, a greater cooling effect can be expected with increased sweat production. In order to keep the cooling effect within a comfortable range for the wearer (depending on the basic settings made in the app), the air in-flow is reduced when the air humidity/inside air humidity rises.

In certain embodiments, the functional units comprise lighting elements arranged at the outer face of the torso portion thus allowing to illuminate the immediate surrounding in front of the face of the wearer. Preferably, the lighting elements comprise LED strips.

The functional units of the protective personal garment of the present invention can also comprise a communication system comprising one or more microphones and one or more speakers which are preferably arranged at the collar of the torso portion, i.e. close to the mouth and ears of the wearer. Accordingly, the wearer can use the phone capabilities of the mobile phone without having to remove the mobile phone from the storage where it is located.

The microphones and/or speakers can be controlled by the first micro-controller. In other embodiments, the communication system comprises a second, dedicated microcontroller which is electrically connected to the first micro-controller and to said one or more microphones and said one more speakers.

In certain embodiments, the functional units comprise a fall sensor which typically comprises an accelerometer. The fall sensor can be a dedicated element or an element integrated within the first micro-controller. It is also possible to use an accelerometer of commercially available mobile phones for this purpose. In essence, data of the accelerometer allow determining, whether the wearer of the protective garment is experiencing sudden unusual accelerations, which can, by suitable software analysis, be attributed to a fall or an inadvertent tripping of the wearer of the protective garment. If a fall is detected, the control unit can trigger a warning and/or an alarm ^: ‘ - ^K -' relaying an emergency message to an emergency response center and

M/63092-PCT Technical Connectivity Wear GmbH

7 users of the mobile phone app and/or flashing the lighting elements of the personal garment and/or by using the speakers of the personal garment to sound an alarm in order to notify other people in the area of the wearer.

The micro-controller can also comprise a geolocation unit, for instance a satellite-based geolocation unit, such as a GPS sensor, which allows determining the location of the protective personal garment. The geolocation unit can be part of the first microcontroller or can be a dedicated element. Alternatively, if the control unit is a mobile phone which is already equipped with a geolocation sensor, it is also possible to use the geolocation sensor of the mobile phone for determining the location of the protective personal garment. The geolocation data can be included in an alarm message or emergency call if, for instance, an emergency is detected via the above-described fall sensor.

In one embodiment, a software application running on the control unit implements an escalation scheme if a fall from height is detected, e.g. when the wearer works on a scaffolding or a work platform.

In a first step, the control unit, e.g. a smartphone app, asks for feedback from the user, whether the user is uninjured or needs help, e.g. by displaying a SOS screen.

In a second step, if no feedback is received from the wearer, lighting elements and speaker elements of the protective personal garment are triggered to release an acoustic and optical alarm. This may alert the wearer that he or she might have missed the feedback inquiry in the first step but may also alert near-by co-workers in case of a real emergency. In one embodiment, light emitting diodes (LEDs) light up alternately in red and white and speaker such as a piezoelectric alarm generator produces a loud signal tone.

In a third step, other users in the vicinity are informed via the application software that help is needed. The users can be imformed via a map display about the precise location of the accident, using e.g. position data obtained via a dedicated geo-location unit of the protective garment or the control unit/mobile device. In one embodiment, the wearer and other users are connected to a dedicated backend and information is exchanged via the backend. Such a backend can, e.g. be implemented via Google r ^: ~' ¹ -

In a forth setp, a message is sent to an emergency hotline. The hotline receives the current user position and possibly deposited user data in order to initiate a suitable rescue chain as efficiently as possible. The emergency functionality can also be easily accessed by the wearer at any time using the application software.

In one embodiment, the control unit can implement a dead-man’s switch functionality, i.e. if no movement of the wearer of the protective personal garment is detected for a preset time, the above emergency chain is triggered.

The mobile phone itself can be stored in various places as long as the mobile phone is capable of establishing a data communication with the first micro-controller. In certain embodiments, however, the protective personal garment comprises a pouch for housing the mobile phone, with the first micro-controller being configured to establish a data communication with the mobile phone housed in the pouch.

In a preferred embodiment, the functional units comprise an inductive charging element arranged in the pouch so that the mobile phone can even be charged via the one or more sources of electrical energy used to power the micro-controller and the functional units of the protective personal garment. It is also possible to send an alarm message via the mobile phone to dedicated predetermined recipients so that the predetermined recipients are immediately informed of a potential safety hazard without requiring further intervention of the wearer of the protective personal garment. It can also be envisioned that before or immediately after an alarm is issued, the wearer of the personal garment is notified of a detected event and has the possibility to cancel the alarm within a predetermined period of time if, for instance, a fall of the wearer has been detected in error.

Preferably, the one or more sources of electrical energy are not integrated with the protective personal garment but can be worn as separate elements, for instance in pouches of a separate belt. In this case, the user simply has to establish a connection via the sources of electrical energy, for instance accumulators, and the connectors of the protective personal garment.

The present invention also concerns a protective garment system comprising the protective personal garment as described above and an application program downloadable on a mobile device such as a mobile phone, wherein the application program is configured for data communication with the first micro-controller of the protective personal garment.

In one embodiment, the application program on the mobile device performs a full control of the functional units of the protective personal garment via a wireless data connection, e.g. via a Bluetooth data connection. Preferably, other than the mobile device running an application software, no further control elements are provided. The mobile device can be connected to an internet database backend, accessed e.g. via a mobile phone network. The backend processes data such as the current position of the wearer to inform other users in the vicinity in the event of an emergency. The alerting of users in the vicinity of an emergency can also be more granular, e.g. in a first step only employees of the same company are alerted and in a second step all wearers of the same type of protective personal garment are alerted. In addition or alternatively, the alerting radius can be extended successively. Such configuration can flexibly be adapted via the the backend.

The present invention will now be described in more detail making reference to a preferred embodiment depicted in the attached drawings.

In the embodiments shown in Figures 1-5, the protective personal garment of the present invention is a safety jacket. In the Figures, the safety jacket is generally designated with reference sign 10.

As can be taken from the Figures, the safety jacket 10 has a torso portion 11 having an inner face 12 (c.f. Fig. 3) and an outer face 13 (c.f. Figs. 1 and 2) and a left arm sleeve 14 and a right arm sleeve 15, both extending from the torso portion 11. The left arm sleeve 14 and the right arm sleeve 15 also have respective outer faces 16, 17 and inner faces (not specifically depicted in the drawings but can be inferred from the drawings).

From the outer views of Figs. 1 and 2, it can be taken that the protective jacket 10 is equipped with typical features of a safety jacket such as reflective strips 18 to increase visibility of the wearer applied to the outer faces 13, 16, 17 which are typically made of a resistant, durable material such

The torso portion 11 is provided with a collar 19 at its upper end. In the depicted embodiment, a hood 20 is attached in the collar region. In preferred embodiments, the hood 20 is configured as an outer hood, e.g. a helmet hood, and an inner hood, e.g. a balaclava, allowing the user to choose whether to wear either the inner hood or the outer hood or both.

The left arm sleeve 14 is provided with a pouch 21 for housing a mobile phone (not depicted in the drawings). The pouch 21 can be provided with a protective cover and/or a removable flap.

In the middle and upper parts of the torso portion 11 , lighting elements such as LED strips 22, are provided which allow to illuminate the area in front of the wearer.

In the views of Figs. 1 and 2, the jacket 10 is shown in a closed position. For instance, a zipper closure can be used (not visible in the drawings) which, in the closed position can be further protected by an external protective strip 23 provided with hook-and-loop fasteners (Velcro strip).

In the view of Fig. 3, the two front parts of the torso portion 11 are opened to reveal the inner face 12 of the torso portion. As can be taken therefrom, two cooling ducts 24 are provided on the inner back side of the jacket 10 and fans 25 are attached to the lower end of the cooling ducts 24. The fans allow to circulate air from the surrounding environment into the inner side of the jacket to cool the torso of the wearer. Also visible in Fig. 3 is an electrical connector 26 which allows establishing an electrical connection with an external energy source, such as one or more accumulators stored, for instance in a belt pouch of the wearer (not depicted in the drawings).

In the outside and inside views of Figs. 1-3, functional elements arranged between various layers of the jacket are not visible. Therefore, Figs. 4 and 5 depict a representation similar to Figs. 1 and 2 but in a schematic semi-transparent view allowing to show possible locations of various elements. In contrast to Fig. 1 , the hood 20 has not been depicted in Figs. 4 and 5 for simplicity reasons.

As can be taken from Figs. 4 and 5, a first micro-controller 27 is arranged in the torso portion 11 of the jacket 10 which functions an electrical control to various elements of the jacket. In the collar 19, microphones 28 and speakers 29 are provided as communication elements. In the depicted example, a second, dedicated micro-controller 30 for the communication elements is provided which is electrically connected to the first mirco-controller 27. In other embodiments, the first micro-controller can also be configured to control the communication elements directly.

The first micro-controller 27 can also comprise a fall sensor which typically includes a three-axis accelerometer for determining unusual accelerations of the protective personal garment which may be attributed to a fall. The first micro-controller 27 can be configured to initiate an alarm, for instance via the built-in lighting elements 22 and/or the built-in speakers 29 to attract attention of co-workers in the immediate area of the wearer of the protective personal garment. Additionally or alternatively, the first microcontroller may initiate an emergency call via the mobile phone. The emergency call may include geolocation data obtained, for instance, via a satellite navigation sensor included in the micro-controller board or via the geolocation units typica"” ^: - commercially available mobile phone.
