Description

AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT A DEVICE FOR EMITTING AN ALARM SIGNAL The following statement is a full description of this invention, including the best method of performing it known to us: Field of the Invention [001]The present invention relates to security products and in particular to a device for emitting an alarm signal. [002] The invention has been developed primarily for use as a device for interfacing with a lamp socket and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use and may, for example, be deployed so as to interface with plug sockets and the like or in stand-alone configuration. Background [003] Existing security systems today generate alarm signals in response to one or more alarm events, such as unauthorized intrusion and the like. [004] However, existing security systems require installation and as such systems are not portable, require a user to install a security system at each required location. [005] The present invention seeks to provide a device for emitting an alarm signal which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative. [006] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country. Summary [007] Existing security lighting systems today have one important and crucial deficiency: the house owner and/or neighbours may not be aware of an intruder if they are asleep as the lighting may not be sufficient to wake them up. According to one aspect, the claimed invention seeks to address this crucial deficiency in a cost effective manner, including by enhancing such an existing infrastructure by utilizing just one lamp socket. The device may be plugged in or screwed into a lamp socket such that when an intruder triggers the security light, the device sounds a loud but adjustable audio signal, or if stealth is required, a radio or even video signal to silently photograph the intruder and sound the alarm signal silently.

[008] Furthermore, the device may be adjusted to trigger even in the day time so as to be used during the day. Yet further, various form of the device may be employed such that a user can achieve the desired operation simply by replacing one customised device with another customized device. [009]According to one aspect, there is provided a device comprising an alarm module adapted for emitting an alarm signal, a trigger module adapted for determining an alarm event, the trigger module coupled to the alarm module; and a lamp socket interface. [010] Advantageously, the device is adapted for use by consumers for security purposes wherein existing infrastructure such existing lamp sockets may be employed so as to allow the device to be deployed by consumers with no or minimal modification to existing infrastructure. Where an existing security lighting infrastructure is used, a detection module will not be needed, thus much cheaper and easier to install for use during the day or night, with dependability and reliability of the tried and tested units already available. [011] Preferably, the trigger module comprises a movement detector. [012]Advantageously, the device may be used to detect the motion of an intruder and emit an alarm signal in response to ward off the intruder. [013] Preferably, the alarm signal is a radio frequency signal. [014]Advantageously, the radio frequency signal may be used so as not to alert an intruder as to the alarm. Furthermore, the radio frequency signal may be used for sending an alarm signal over large distances. [015] Preferably, the lamp socket interface comprises a power converter coupled to the lamp socket interface. [016]Advantageously, the device is adapted to draw power from a lamp socket. [017] Preferably, the trigger module comprises an edge detector adapted for detecting changes in power supply. [018]Advantageously, the device is adapted for detecting changes in the power supply of a lamp socket so as to control the alarm module accordingly. Further, the lamp socket interface may be coupled directly to the alarm module so as to reduce cost. Additionally, a transformer, bridge rectifier, smoothing capacitor and the like may be used. [019] Other aspects of the invention are also disclosed.

Brief Description of the Drawings [020] Notwithstanding any other forms which may fall within the scope of the present invention, preferred embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings in which: [021]Fig. 1 shows a device for emitting an alarm signal in accordance with a preferred embodiment of the present invention. Description of Embodiments [022] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features. [023] Fig. 1 shows a device 100 for generating an alarm signal. As will be described in further detail below, the device 100 is adapted for use by consumers for security purposes. Additionally, the device 100 is adapted for use with existing infrastructure such existing lamp sockets so as to allow the device 100 to be deployed by consumers with no or minimal modification to existing infrastructure. [024]The device 100 as shown in Fig. 1 is depicted as having an outer profile in accordance with that of a standard lamp globe. Such an outer profile advantageously allows the device 100 to confirm to standard lamp sockets and lamp covers. Furthermore, such an outer profile may serve in making the device 100 inconspicuous so as not to alert an intruder, for example. [025] However, it should be noted that the shape of the device 100 may vary according to various applications. For example, the device 100 may be substantially circular or elongate in shape. [026]As is shown in Fig. 1, the device 100 comprises an alarm module 110 adapted for emitting an alarm signal. The alarm signal is adapted for alerting a user of a potential alarm event. In this manner, the device 100 may be deployed in one (or several locations) at one or more conveniently located lamp sockets for the purposes of warning a user of a potential alarm event. [027]In this regard, as is further seen in Fig. 1, the device 100 further comprises a trigger module 105 adapted for determining an alarm event. As is seen in the figure, the trigger module 105 is coupled to the alarm module 110 for the purposes of activating the alarm module 110. [028]The device 100 further comprises a lamp socket interface 115 allowing the device 100 to interface with a standard lamp socket. As will be described in further detail below, the lamp socket interface 115 not only allows the device 100 to be secured in place by a conveniently located lamp socket, but also to draw power from the lamp socket in certain embodiments. The lamp socket interface 115 may be suited for securement within various types of lamp sockets, such as bayonet and screw-type lamp sockets, and AC or DC lamp sockets, for example. [029] It should be noted that while the embodiment described in the figure is globe shaped, in certain embodiments the device 100 is adapted to interface between a lamp socket and a lamp so as to permit the use of a lamp without unnecessarily occupying a lamp socket. In this respect, the device 100 further comprises a complementary lamp socket interface 115 (not shown) for receiving a lamp therein. [030]The device 100 may be made from various materials depending on the application. For example, the outer surface of the device 100 may be glass in conformance with a standard globe. However, in preferred embodiments, the material is selected for strength and durability purposes. The body of the device 100 may furthermore be selected from a material so as not to attenuate the alarm signal from the alarm module 110 as described herein. For example, where the alarm signal is a visible light signal, the material of the body would be transparent. The device 100 may be further manufactured so as to withstand the elements, including temperature fluctuations, rain and dust, and the deteriorating effects of the sun. [031]In one embodiment, the alarm module 110 emits an audible or ultrasonic alarm signal. In this manner, the alarm module 110 may comprise an electric buzzer. As such, the alarm may alert a user within audible range of the buzzer. For example, the device 100 may be inserted into a lamp socket of a motion sensitive flood light, such as a flood light situated outside a user's house. When the floodlight detects motion and powers the lamps, the device 100 emits an audible signal such that the user can hear that the floodlight has actuated. In certain embodiments, the device 100 may comprise message playout means so as to be able to play out a warning message, for example. The body of the device 100 may be suited to allow the non-attenuation of the audio signal while remaining weather proof. For example, the device 100 may comprise a flexible rubber membrane adjacent the alarm module 110, adapted to vibrate to transmit the signal while preventing the egress of water therein. [032]In an alternative embodiment the alarm module 110 may comprise a radio transmitter such that the alarm signal is a radio frequency signal. The radio transmitter may be a low cost radio transmitter such as used in garage door openers allowing a suitable receiver within a 50m radius, for example, to receive the alarm signal. The radio transmitter suits the device 100 for applications where an audible alarm is unsuitable, such as where the device 100 is out of audible range or where a user is hard of hearing, for example. Furthermore, the radio transmitter can be used for control, such as by coupling the radio receiver to an alarm system such that the alarm system activates upon receipt of the radio frequency alarm signal from the device 100. For embodiments comprising signaling over larger distances, the alarm module 110 may comprise a GSM module so as to be able to transmit SMS messages. [033]In one embodiment, the device 100 may comprise a video device (not shown) such that the radio signal comprises a video signal. In this manner the user may watch the video signal on a video display device. In an alternative embodiment, the device 100 may comprise on-board storage, such as by way of secure digital (SD) memory for the purposes of storing video data. [034] In various embodiments the device 100 may comprise a battery (not shown) for powering the device 100. In this regard, the device 100 may comprise a battery aperture for allowing for the replacement of the batteries. In a specific embodiment, the device 100 comprises a solar panel, such as secured to the outer surface of the device 100, for the purposes of powering the device 100. [035]However, in a preferred embodiment, the lamp socket interface 115 comprises a power converter 120 adapted coupled to the lamp socket interface 115. In this manner, the device 100 is able to draw power from the lamp socket, removing the need to auxiliary power supply. In one embodiment, the device 100 becomes operable upon the supply of power, however, in other embodiments, the device 100 may comprise battery storage, rechargeable via the power converter 120, such that the device 100 may operate in the absence of power supply from the lamp socket. The power converter 120 preferably is an AC to DC power converter 120 and is further preferably a solid state power converter 120 so as to minimize space requirements and heat dissipation as compared to traditional power converters having windings. For DC applications where the device is used in campervans, boats, cars and the like, the power converter 120 may be a DC to DC converter, such comprising voltage regulation, buck or boost converters and the like. The power converter 120 may additionally comprise over voltage or over-current protection, such as Zener clamping, fuses and the like. [036]Where the device 100 is adapted for operation in accordance with the supply of power from a lamp socket, the trigger module 105 comprises an edge detector adapted for detecting changes in power supply. The edge detector is therefore able to determine the supply and disconnect of power to the device 100, thereby allowing the device 100 emit an alarm signal accordingly. For example, the device 100 may be deployed in a house such that when an intruder operates a light switch, the edge detector of the device 100 detects the supply of power and emits an alarm signal accordingly. The edge detector may be coupled to a suitable rectifier and smoothing circuit as necessary so as to be able to perform edge detection on alternating currents too. [037]In one embodiment, the trigger module 105 comprises a movement detector. In this manner, the device 100 is suited to emit alarm signals where power edge detection or auxiliary motion detection as described above is not suitable. Specifically, the device 100 may comprise a passive infrared (PIR) or similar motion detection device 100 so as to be able to detect motion. [038]In other embodiments, the trigger module 105 may be adapted to trigger in accordance with other stimulus, such as by detecting sound, fluctuations in light, fluctuations in temperature and the like.
