DETAILED DESCRIPTION

A security system according to an embodiment of the present invention will now be described with reference toFIG. 1.

The security system for personal protection comprises a first unit1and a second unit2separate from the first unit1. The first unit1comprises a camera device, a microphone device, a siren device, a safety device, an attachment device, and a communication device for communication wirelessly with the second unit2. The second unit2comprises a microphone device and a communication device for communication wirelessly with the first unit1, the second unit further comprises a communication device for wirelessly sending an alarm message to a network of one or more recipients. The safety device may be integrated in the attachment device. When an alarm is triggered, the security system activates both the microphone device of the first unit1as well as the microphone device of the second unit2, such that the alarm message contains an audio recording from an environment of a user of the security system. In this way, even if e.g. the first unit1is manipulated or destroyed, an audio recording is sent together with the alarm message.

The first unit1thus comprises attachment means for attachment of the first unit1on a user during use of the security system, registration means for registration of surroundings of the user, alarm means for sounding a siren, and communication means for communication wirelessly with the second unit2.

The second unit2thus comprises registration means for registration of surroundings of the user and communication means for communication wirelessly with the first unit1, the second unit further comprises communication means for wirelessly sending alarm messages to a network. The communication means of the second unit2is configured to send an alarm message to the network when triggered e.g. by the first or the second unit being manipulated, and/or when a voice command is registered through the registration means of the first unit or of the second unit, and/or when an actuator of the safety device is triggered. The second unit2may communicate wirelessly with a base station3of e.g. a cellular network, to access the network of recipients. The network of recipients may comprise personal connections or a general emergency central, such as112within the EU. An alarm message may be sent to one or multiple recipients of the network.

The first unit1is during use preferably attached to a user through the attachment device, and the second unit2is during use preferably carried by that user. The second unit is preferably a portable radio communication device, such as a mobile phone, smart phone or similar device, and the first unit is preferably an auxiliary device to the portable radio communication device. The auxiliary device may be sold separately from the portable radio communication device and configured to communicate wirelessly to a smart phone.

The first unit1preferably further comprises a positioning device and, and the second unit may further comprises a positioning device, the positioning devices providing geographical positions. With the provision of a positioning device, such as a GPS receiver, in the first unit, an alarm message provided with a geographical position sent to the network can instantly identify where a person is. By having a positioning device in the second unit the same advantage is achieved. By having a positioning device in both units, also a backup is achieved in case the first unit is manipulated or destroyed.

The first unit1preferably further comprises a warning light, which is arranged to visually indicate when the security system is activated. A possible attacker will in this way be deterred from attacking the user of the security system.

The security system may be activated/deactivated through a user-verification on the second unit. When the security system is activated an alarm message is sent when triggered. Recordings of the surroundings may, when the security system is activated, continuously record audio of the surroundings of the user, but only save e.g. the last couple of seconds or minutes to be send upon triggering of an alarm.

For triggering the alarm of the security system, a voice command may be given, which may be received by the first and/or the second unit and processed, preferably in the second unit. Alternatively, or additionally, the security system may be triggered by the safety device. The safety device may comprise a proximity sensor, for detecting the distance to the second unit, a switch sensor for detecting when the attachment device is being opened, an accelerometer detecting sudden movements of the first unit, and/or a contact sensor for detecting removal from the user. The proximity sensor is preferably triggered when the distance between the first and second unit is over e.g. two meter. The shorter trigger distance that is selected, the higher risk for falsely triggering of alarm, and the higher distance selected the higher risk for no triggering of alarm in an actual unsafe situation. Detection of opening of the attachment device may be arranged through magnetic contacts, micro switches or similar devices.

Placement of the first unit is preferably high and visible on the user, such as in the form of earpiece, necklace, ring, bracelet, glasses, or clothes in the form of a hat or a shoulder piece.

Further, the security system may comprise a third unit, separate from the first and second units. The third unit may comprise a chip with a positioning device and a communication device, hidden on the user. The third unit may even be implanted under the skin of the user. The third unit is preferably only activated by the first or the second unit upon activation of an alarm. By only being activated upon activation of alarm energy is saved, and the third unit may e.g. intermittently transmit a geographical position of the user to the network of recipients to further save energy.

A method for personal protection is presented with reference toFIG. 2, comprising the steps in the following order:recording audio in a first unit1and in a second unit2separate from the first unit1,detecting10manipulation in the first unit1wirelessly connected to the second unit2, or detecting10a voice command in the first unit1and/or in the second unit2;recording11video and audio in the first unit1and audio in the second unit2;producing12an alarm signal in the first unit1; andsending13a message to a network from the second unit2. The message includes an audio recording from the first and/or the second unit.

The method may further comprise the step of producing an alarm signal in the second unit2.

A security arrangement1for personal protection is also presented, comprising a camera device, a microphone device, a siren device, a safety device, an attachment device, and a communication device for communication wirelessly with a portable radio communication device2.

The camera device and the microphone device are configured to register data of surroundings of a user and are configured to send the registered data to the portable radio communication device, when triggered by the safety device, the attachment device or when an instruction is received from the portable radio communication device.

The siren device is configured to sound an alarm when triggered by the safety device, the attachment device or an instruction received from the portable radio communication device.

FIG. 3is a schematic diagram showing functional blocks of the security system. The modules may be implemented as only software instructions such as a computer program executing in first or second unit or only hardware, such as application specific integrated circuits, field programmable gate arrays, discrete logical components, transceivers, etc. or as a combination thereof. In an alternative embodiment, some of the functional blocks may be implemented by software and other by hardware. The modules correspond to the steps in the method illustrated inFIG. 2, comprising a detect manager30, a record manager31, a produce manager32, and a send manager33. In the embodiments where one or more of the modules are implemented by a computer program, then it shall be understood that these modules do not have to correspond to programming modules, but can be written as instructions according to the programming language in which they would be implemented, since some programming languages do not typically contain programming modules.

The detect manager30is configured to detect triggering of an alarm. This module corresponds to the detect step10ofFIG. 2. This module can e.g. be implemented by a processor, when running a computer program.

The record manager31is configured to detect record voice data and/or image data surrounding the user. This module corresponds to the register step11ofFIG. 2, and also the previous registration of audio. This module can e.g. be implemented by a processor, when running a computer program.

The produce manager32is configured to sound an alarm. This module corresponds to the alarm step12ofFIG. 2. This module can e.g. be implemented by a processor, when running a computer program.

The send manager33is configured to send an alarm message to a network of recipients. This module corresponds to the send step13ofFIG. 2. This module can e.g. be implemented by a processor, when running a computer program.

The security system may thus have a first unit with built-in camera, voice recognizer, GPS navigation and siren. The first unit may communicate with a user's own mobile that also may record audio and GPS. If an attacker would have time to throw away the camera part module, i.e. the first unit, the mobile also capture voice and may capture geographical position for some time before help arrives. The security system acts when you need help.

With a simple voice code, e.g. “help”, you may trigger the alarm which immediately registers audio and may take pictures and video records the situation and forthwith transmit them to the network of recipients. An alarm may be sent with a built-in code that can provide all information about the emergency, voice recording, image capture, and a positioning data with address of an alarm text that is sent. When a receiver of an alarm message is a personal connection, that person may take personal action or may contact a general emergency central.

Both people in the network and security guards can act in real time. All information is preferably archived in a central unit in the network. The security system may have a safety latch mounted, and an activation/deactivation code may be wrapped, or a particular voice code may be used, before the first unit is turned off so that no attacker can remove the first unit without the alarm goes off. An alarm message preferably goes away regardless of if the first unit is deactivated unintentionally by the user or intentionally by an attacker. The alarm message will at least include an audio recording of the surrounding of the user. The attacker will be documented and all will be archived even if the attacker would destroy the visible first unit. The first unit works with the mobile, i.e. the second unit, and although an attacker may have time to make an assault, it minimizes the risk when a loud alarm also goes off from the first unit and possibly also from the mobile.
