Definitions

  • This invention generally relates to a personal attack alarm. More particularly, the invention relates to a personal attack alarm adapted to be activated by a user, when the user wishes to summon help, and where the personal attack alarm comprises a portable unit adapted to be worn by the user and a communications unit.
  • the robbers have in recent years turned to private homes as an easy target of their criminal activity. It is not any longer a question of simple burglars operating when the residents are not at home. On the contrary, many of the robbers prefer that the residents are at home, so they can force them into telling where they keep their valuables and turn over their credit cards and security codes. Commonly, but not exclusively, they chose the homes of elderly people to avoid being met with too much resistance.
  • the robbers may need time to get away and to cash as much money as possible on the stolen credit cards. For this reason they are tying up the residents and muting them using for example adhesive tape.
  • such criminals may eliminate all means of communication from the house. They will force the persons to hand over their mobile telephones and may make fixed line telephones inoperable. The residents are left in a hopeless situation, as it may take a long time before relatives or neighbours notice, that something is wrong.
  • the personal attack alarm described in this patent application will allow the residents to summon help at an early stage of the robbery or even after they have been tied up and muted, without the robbers noticing it.
  • Another application of the personal attack alarm is aimed at persons in risk of being attacked outside their home for example because for one reason or another they are going about the streets at night or live in insecure neighbourhoods. These people may be teen-agers or women in risk of being attacked. People may also be at risk of being mugged or assaulted due to their work, e.g. gas station attendants, personnel in shops with late opening hours, night security personnel, social workers and personnel in fast food restaurants.
  • GB2285878A discloses a personal attack alarm comprising an alarm carrying member and means for producing an audible alarm consisting of one or more human screams.
  • the audible alarm comprises a sequence of human screams interspersed by one or more audible siren tones, in the preferred embodiment this sequence is continuously repeated in a loop.
  • the attack alarm has a wrist band for securing the alarm carrying member about a user's wrist, the strap and alarm carrying member forming a closed loop which remains closed even when the attack alarm is being secured about or removed from [he user's wrist.
  • One end of the strap is coupled to the alarm carrying member by a safety catch.
  • GB2279787A discloses a battery operated personal attack alarm which is activated by a two stage operation. The first stage of activation is effected before the user deems an attack likely by the release of safety catch, and the action of holding the alarm in the hand prevents the alarm from sounding as the second stage of the activating mechanism is held in an off position. If the user releases the alarm, the alarm buzzer sounds and cannot be turned off until the device is reset, by lhe users, by means of a pin, key or combination lock.
  • US5003294A discloses an infra-red remote personal alarm system consisting of a portable transmitter unit which is intended to be worn or to be manually carried by the user, and which is operabie by lhe user at any particular location to transmit an alarm signal in an emergency and which is to be received by a centrai receiving station so that appropriate action can be initiated in response thereto.
  • the transmitter unit is electrically operabie and includes means for transmitting pulsed infra-red alarm signals which can be picked-up by an infra-red signal receiver at the location of the user, and then retransmitted as an oscillating electrical signal via direct wiring to the central receiving station as a warning signal indicative at location monitoring points of the location from which the emergency call has been made.
  • US2007171084A discloses a personal safety device comprising a casing having a torch and a smoke detector at opposite ends.
  • the smoke detector When not in use, the smoke detector is protected by an end cap making a water tight seal with the casing.
  • the end cap is biased to slide away from the casing when unlatched, exposing a louvered chamber containing the smoke detector.
  • the smoke detector is automatically activated when the chamber is exposed, and should it detect a fire operates both an audible alarm and the torch. Buttons are provided to allow activation of the audible alarm as an attack alarm or controllabiy as a signalling device.

Description

Personal attack alarm
Field of the invention
This invention generally relates to a personal attack alarm. More particularly, the invention relates to a personal attack alarm adapted to be activated by a user, when the user wishes to summon help, and where the personal attack alarm comprises a portable unit adapted to be worn by the user and a communications unit.
Background of the invention
With the improvement of the alarm systems of the customary targets of robbers, such as banks, jewellers, gas stations etc., the robbers have in recent years turned to private homes as an easy target of their criminal activity. It is not any longer a question of simple burglars operating when the residents are not at home. On the contrary, many of the robbers prefer that the residents are at home, so they can force them into telling where they keep their valuables and turn over their credit cards and security codes. Commonly, but not exclusively, they chose the homes of elderly people to avoid being met with too much resistance.
After this kind of robbery, the robbers may need time to get away and to cash as much money as possible on the stolen credit cards. For this reason they are tying up the residents and muting them using for example adhesive tape. As the first task, such criminals may eliminate all means of communication from the house. They will force the persons to hand over their mobile telephones and may make fixed line telephones inoperable. The residents are left in a hopeless situation, as it may take a long time before relatives or neighbours notice, that something is wrong. The personal attack alarm described in this patent application will allow the residents to summon help at an early stage of the robbery or even after they have been tied up and muted, without the robbers noticing it.
Another application of the personal attack alarm is aimed at persons in risk of being attacked outside their home for example because for one reason or another they are going about the streets at night or live in insecure neighbourhoods. These people may be teen-agers or women in risk of being attacked. People may also be at risk of being mugged or assaulted due to their work, e.g. gas station attendants, personnel in shops with late opening hours, night security personnel, social workers and personnel in fast food restaurants.
GB2285878A discloses a personal attack alarm comprising an alarm carrying member and means for producing an audible alarm consisting of one or more human screams. In one embodiment the audible alarm comprises a sequence of human screams interspersed by one or more audible siren tones, in the preferred embodiment this sequence is continuously repeated in a loop. The attack alarm has a wrist band for securing the alarm carrying member about a user's wrist, the strap and alarm carrying member forming a closed loop which remains closed even when the attack alarm is being secured about or removed from [he user's wrist. One end of the strap is coupled to the alarm carrying member by a safety catch.
GB2279787A discloses a battery operated personal attack alarm which is activated by a two stage operation. The first stage of activation is effected before the user deems an attack likely by the release of safety catch, and the action of holding the alarm in the hand prevents the alarm from sounding as the second stage of the activating mechanism is held in an off position. If the user releases the alarm, the alarm buzzer sounds and cannot be turned off until the device is reset, by lhe users, by means of a pin, key or combination lock.
US5003294A discloses an infra-red remote personal alarm system consisting of a portable transmitter unit which is intended to be worn or to be manually carried by the user, and which is operabie by lhe user at any particular location to transmit an alarm signal in an emergency and which is to be received by a centrai receiving station so that appropriate action can be initiated in response thereto. The transmitter unit is electrically operabie and includes means for transmitting pulsed infra-red alarm signals which can be picked-up by an infra-red signal receiver at the location of the user, and then retransmitted as an oscillating electrical signal via direct wiring to the central receiving station as a warning signal indicative at location monitoring points of the location from which the emergency call has been made.
US2007171084A discloses a personal safety device comprising a casing having a torch and a smoke detector at opposite ends. When not in use, the smoke detector is protected by an end cap making a water tight seal with the casing. The end cap is biased to slide away from the casing when unlatched, exposing a louvered chamber containing the smoke detector. The smoke detector is automatically activated when the chamber is exposed, and should it detect a fire operates both an audible alarm and the torch. Buttons are provided to allow activation of the audible alarm as an attack alarm or controllabiy as a signalling device. The torch comprises one or a plurality of white LEDs for conventional illumination and optionally a red LED for signalling and for illumination without loss of night vision.
GB2227344A discloses a radio operated personal attack alarm consisting of a main alarm unit containing the radio receiver, and incorporating a siren, strobe lights and an illuminating message panei upon which the address of the location being visited is written. The user would typically leave the main unit in a car parked nearby, carrying only a hand-held transmitter, in the event of an emergency, the user activates the alarm unit by means of the radio signal from the transmitter, and both the cry for help and the iocation are thus clearly communicated to a public place, with a request for immediate and appropriate assistance.
It remains a problem to provide a personal attack alarm which is easy to wear and activate, such that it can be used by all kinds of people, including old people and people which are physically disabled, and a personal attack alarm which can be worn and activated without an offender noticing it.
Summary
Disclosed is a personal attack alarm adapted to be activated by a user, when the user wishes to summon help, comprising:
- a portable unit adapted to be worn by the user;
where the portable unit is adapted to transmit a signal to a receiver of the alarm, when the user activates the alarm; and
where the signal is transmitted by means of a telecommunications network;
wherein the user activates the alarm by urinating, and
where the portable unit comprises a wetness sensor and a transmitter, and
where the wetness sensor is adapted to be arranged to be hit by and to detect the user's urine. Consequently, it is an advantage that the personal attack alarm can be used by persons who want to attain a maximum of personal security, since the portable unit to be carried by the user is very small and comfortable, almost unnoticeable in use. Furthermore, it is an advantage that the alarm may be released at any time of the attack without the attacker noticing it. It may be advisable to trigger the alarm at an early stage of the attack so that help and rescue can be summoned as quick as possible. A yet further advantage is that the personal attack alarm is at a permanent location and does not require any hands-on action to trigger the alarm.
Thus the portable unit is adapted to be arranged in the user's underwear or anywhere else where it can detect urine from the user. The wetness sensor may be developed only to react to urine and not to for example plain water. This will prevent the alarm from being activated, if the user is soaked in a heavy rain shower or spills water by accident.
Preferably the user activates the alarm by urinating voluntarily with the purpose of activating the alarm.
In some embodiments the personal attack alarm further comprises:
- a communications unit;
where the portable unit is adapted to transmit a first signal to the communications unit, when the user activates the alarm;
where the communications unit is adapted to transmit a second signal to the receiver of the alarm, and where the second signal is transmitted by means of the telecommunications network. The transmitter transmits a signal indicative of wetness-detection to the communications unit, whereby the alarm is activated.
The first and the second signal are adapted to be transmitted by means of electromagnetic communication.
The communications unit can be arranged together with the portable unit such as arranged integrally with the portable unit as one device or unit. Alternatively, the communications unit can be arranged in proximity to the user such as in the user's home, in the user's pocket, integrated in the users wrist watch, etc.
The receiver of the alarm may be a security alarm company, a security man working for the security alarm company and/or one or more trusted persons belonging to the user's family, circle of friends, neighbours etc. If the entity receiving the alarm is a security company, they will immediately take appropriate action and may furthermore contact the other trusted people receiving the alarm, to coordinate the joint action to be taken. In some embodiments the alarm may be transmitted to the security alarm company and one or more trusted persons simultaneously. The receiver may be alerted by an audible alarm, when an alarm signal has been received.
The portable unit is a device which is hidden on the person and which releases a signal, the first signal or signal 1 , when activated. The unit is a portable micro size transmitter adapted to be placed in the person's underwear or nightgown. The attacker will most certainly keep the attacked person from using any obvious communication device, such as telephones, both stationary or mobile, or separate alarm devices, for example devices to be picked up from the night table, or out of a pocket or purse, and which is released by pressing a push-button on it.
Thus it is an advantage that the attacker cannot prevent or hinder the attacked person from urinating, and when the attacked person urinates, a wetness or moisture sensor integrated with the micro transmitter in the person's underwear will release the alarm signal.
It is an advantage that the portable unit is wireless and has as such no wires attached.
It is an advantage that the portable unit is adapted to be placed at a location, where it will immediately react to the moisture, when the attacked person is urinating.
The portable unit may be self adhesive, or integrated in a pad of fabric and kept in place by the person's underwear. Alternatively, the portable unit may be fastened to the person in any other way.
The portable unit may be reusable, washable, and with a rechargeable battery. Alternatively, the portable unit may be disposable and delivered in a sterile packing.
The portable unit is activated by means of a wetness sensor, which may comprise a chemical compound, which reacts to and dissolves when the user urinates. Alternatively, the portable unit may comprise an electronic sensor reacting to wetness, or any other transducer reacting to moisture and releasing a triggering impulse.
All parts of the portable unit being in contact with the user or the skin of the user are made of non-toxic material. The Communications unit is a device receiving the first signal or signal 1 and transmitting the information by means of a second signal or signal 2 to those providing assistance.
Thus the Communications unit is a relay device receiving the alarm signal from the transmitter integrated in the portable unit and transmitting it to the receiver or entity from which the call for help is summoned.
It is an advantage that the communications unit is adapted to be hidden for the attacker, since hereby the attacker is not aware of the communications unit and this improves the security for the user.
The communications unit may be integrated in the portable unit, so that these two units constitute one device adapted to be worn in the underwear of the user.
Alternatively, the communications unit may be a separate unit not integrated with the portable unit, but located in the proximity of the user. For example, the communications unit may be arranged in the user's home, integrated in the user wrist watch or the user may carry the communications unit in a bag or in his/her pocket, or the user may leave the communications unit in his/her car, while he/she is walking around.
In some embodiments the communications unit is arranged within a distance of about 40 meters from the user due to the transmission range of the signals. If the connection between the communications unit and the portable unit is cut off, e.g. because the user carrying the portable unit is in a distance of more than 40 meters from the communications unit, the portable unit may provide a signal indicative of disconnection, e.g. by vibrating, so that the user can be made aware of the disconnection. Hereafter, the user can ensure that the communications unit and the portable are connected again, e.g. by moving closer to the communications unit. In some embodiments the Communications unit is arranged in a stationary unit adapted to be placed in the user's home. In this case, where the communications unit is in a fixed installation, this stationary unit may be used exclusively for the personal attack alarm, or it may be part of a system comprising one or more of: a burglar alarm, a fire alarm and/or another alarm in the home. The stationary unit may be arranged in a fixed line telephone or connected to a fixed line telephone.
A comprehensive or assembled alarm system is usually advertised on the main entrance door of the home to keep burglars away, and the attacker will usually disable this system first thing, when they have entered the house. For this reason the stationary unit may be installed as a separate unit in a well hidden place.
In some embodiments the communications unit is a mobile unit adapted to be carried by the user.
The mobile unit may be a mobile telephone adapted to be used in connection with the personal attack alarm.
The mobile unit may be an integral part of a unit incorporating features such as a mobile telephone and a GPS tracking system or any other system transmitting position information. Alternatively, the mobile unit may be a dedicated unit used solely as a part of the personal alarm system, with or without position information. Alternatively, the mobile unit may be any other suitable existing or future communication system. As there is no need for a keyboard and a display on the mobile unit, the size of the mobile unit can be so small, that it can be comfortable kept hidden in the persons clothing. The first signal or signal 1 transmitted by the portable unit to the Communications unit being either a stationary unit or mobile unit may be selected from the electromagnetic communication consisting of:
- infrared communication, - radio frequency communication; or
- microwave communication.
Thus the first signal may be based on radio frequency communication for example using the blue tooth system. Blue tooth is based on a 2.4 GHz short-range radio frequency bandwidth with a max range of 100 meters. Several units using blue tooth may be operated within the same location without interfering with each other.
Alternatively, the first signal may be transmitted from the portable unit to the communications unit by means of any other existing or future means of transmitting signals with a minimum of power consumption over short distances, or by means of ultrasound or the like.
The second signal or signal 2 transmitted by the communications unit to the receiver may be selected from the electromagnetic communication consisting of:
- radio frequency communication; or
- microwave communication.
Furthermore, the second signal is adapted to be communicated over a longer distance than the first signal.
The telecommunications network used for transmitting the second signal from the communications unit to the receiver may be a fixed-line network. Alternatively and/or additionally, the telecommunications network may be a mobile telecommunications network. In some embodiments a fixed-line network and a mobile telecommunications network are used concurrently as the telecommunications network
In case of a stationary communications unit, the second signal or signal 2 may be transmitted by the communications unit by means of a fixed telephone line to the receiver providing assistance, and/or by means of a radio frequency communication utilizing a mobile phone network, and/or by means of any other applicable radio frequency communication. The power supply of the stationary communications unit may comprise that the communications unit is powered by the e.g. 230 volt or e.g. 110 volt supply of the house, and/or may comprise a back-up battery power supply, which is automatically and permanently kept fully charged.
In case of a mobile communications unit, the second signal or signal 2 may be transmitted between the mobile communications unit and the receiver providing assistance by means of radio frequency communication utilizing a mobile phone network, and/or by means of any other suitable radio frequency communication systems, and/or by means of an acoustic signal summoning help from nearby persons.
In some embodiments the personal attack alarm further comprises an activation unit comprising secondary means for initiating the alarm.
The secondary means for initiating the alarm may be by a special button on the activation unit or a set of special buttons. This will allow a user of the system to activate the alarm without urinating, if he/she is in a threatening situation and it is possible to do so.
The activation preferably activates the alarm in the same way as if the user had urinated. The activation unit may be any unit or device, such as a mobile device or a stationary device.
The activation unit may be incorporated into a wrist watch. Thereby a discreet activation unit is provided. This may be an advantage as a user may wear the system without other people present noticing it. The wrist watch may be fitted with a single or a plurality of buttons for initiating the alarm. In an embodiment of the invention, the wrist watch is fitted with two buttons functioning as secondary means for initiating the alarm, where the alarm is initiated if both of the buttons are pushed simultaneously.
The use of two buttons that needs to be pushed simultaneously for the alarm to be initiated may lower the risk of a false alarm.
In some embodiments the activation unit is an integral part of the communication unit.
In some embodiments the activation unit activates the alarm by transmitting an activation signal to the portable unit.
The activation signal may be wireless transmitted.
In some embodiments the personal attack alarm further comprises a microphone for transmitting an audio signal to the receiver of the alarm.
The microphone may be activated at the same time as the alarm is activated. The microphone may be incorporated into the portable unit, the communication unit, the activation unit, or any other unit or device. By sending an audio signal to the receiver of the alarm, the receiver is presented with information enabling the receiver to determine if the alarm is a true alarm or a false alarm. The microphone will additionally enable the user of the alarm to tell the receiver of the alarm vital information such as if the user is hurt an need medical assistance, where the user are or even give a personal description of the users attacker, allowing the police to act fast.
If the user wears the portable unit in his/her home, the receiver of the alarm knows the home address of the user, and for example a security man from a security company may visit the user at the home address to help the user.
However, if the user wears the portable unit outside his/her home, the personal attack alarm may be amended with a device transmitting the position of the attacked person to the receiver/s receiving the call for assistance.
Thus, in some embodiments the location of the user is determined, and the determined location of the user is transmitted to the receiver.
In some embodiments a global navigation satellite system is used to determine the location of the user.
The global navigation satellite system may be the global positioning system (GPS) or any other navigation or satellite tracking system.
Alternative and/or additionally sounding, location or direction finding by means of mobile telecommunications masts may be used to determine the location of the user. Thus alternative means of providing information on the position may be the determination of the location of the telecommunications mast transmitting the alarm signal from the mobile phone, which will thereby provide an approximate position of the attacked person. In some embodiments the position of the user is first determined by use of mobile telecommunication masts, and then determined by a global navigation satellite system.
By using both telecommunication masts and a global navigation satellite system to determine the position of the user, a faster positioning can be achieved allowing the receiver of the alarm to know the position of the user faster.
In some embodiments the location of the user is determined repeatedly.
Thus the communications unit for example in form of a mobile unit with GPS may repeatedly, i.e. at fixed intervals, determine its own position and thus the position of the user.
The communications unit may determine the position at which the attack is taking place only at the moment when the alarm is activated Thus the repeatedly determined location of the user may be performed after the user has activated the alarm or the repeatedly determined location of the user may be performed before the user has activated the alarm.
The repeatedly determined locations may be stored in the mobile unit. Alternatively and/or additionally, the repeatedly determined locations may be transmitted to and stored at the control centre of the security alarm company. Thus the repeatedly determined positions may be constantly transmitted to and stored at the control centre or at any other location of the entity providing assistance, and the determined positions may be recalled and/or displayed when an alarm is received.
In the case of repeatedly determined positions, a number of the latest positions, for example the last 5 positions, are constantly stored in the communications unit, and are transmitted to the receiver together with the alarm signal. Inside a building, the communication to the global navigation satellite system such as the GPS system is usually lost and no position information is transmitted. Thus, if the last five positions determined prior to the user entering a building are known, it is easy for the receiver(s) of the alarm to determine in which building the attack is taking place.
Thus in some embodiments the last determined location of the user is retrieved, if there is no connection to the global navigation satellite system, when the user activates the alarm.
The alarm is adapted to be cancelled by the user or by the trusted persons by performing a telephone call to the security company, for example if the alarm is activated inadvertently. The user may in the telephone call provide or mention a key word to confirm that the cancellation is not forced upon him/her.
Alternatively and/or additionally, a push bottom for cancelling the alarm may be provided, such that the user can easily press the bottom and cancel the alarm, if it was activated inadvertently. The push bottom may be arranged e.g. on a small separate device, on the communications unit or in connection with the communications unit.
Alternatively and/or additionally, a sound, such as a loud noise, may be emitted from the portable unit and/or from the communications unit, when the alarm is activated. If the user activates the alarm due to an attack, the sound may, if it is very loud and annoying, have the effect of discouraging the attacker.
In some embodiments the portable unit is arranged in a panty liner adapted to be worn by the user, where an upper absorbing layer of the panty liner is adapted to absorb a small amount of urine, and where the personal attack alarm is activated, if urine penetrates the upper absorbing layer of the panty liner and reaches the wetness sensor in the portable unit. It is an advantage that the portable unit is arranged in a panty liner with an upper absorbing layer, because if a partly incontinent person uses the personal attack alarm, the alarm will not be activated, if a small drop of urine is released, for example if the user coughs, because the small amount of urine will be absorbed by the absorbing layer of the panty liner.
In some embodiments, the portable unit provides a signal to the user, when the alarm is activated, so that the user is made aware that the alarm is activated.
This is an advantage, if the alarm is activated inadvertently, e.g. by spilled water or rain, or if the user inadvertently urinates on the portable unit without wishing to summon for help. The portable unit may signal that the alarm is activated by e.g. vibrating so that the user can feel this and cancel the alarm, if necessary.
