Definitions

  • This invention relates to a novel means and method of preventing the theft of apparatus that can be disabled from operating by the opening or closure of a switching device
  • this invention is particularly applicable to automobile theft which is a significant problem in most countries around the world and consumes valuable policing resources in attempting to recover stolen automobiles
  • great personal inconvenience is encountered by the owners of stolen vehicles
  • this invention can also be used to remotely control apparatus such as televisions or high fidelity radio sets, the remote control of which lends itself to acting as a deterrent to stealing
  • this invention enables remote control for other reasons such as preventing children from operating devices at times that their parents do not wish them to have access
  • This aspect is of particular relevance to television viewing Whilst this invention is of use in numerous situations, discussion of the prior art is restricted to the field of vehicle immobilisation for the prevention of theft
  • Prior Art means in this area comprises many various approaches ranging from systems for the prevention of theft to the immobilisation of the vehicle after being stolen and ultimately the recovery of the stolen vehicle
  • This invention relates to the field of vehicle immobilisation and in particular to the immobilisation of a user's vehicle by the transmission of radio frequency signals across the public telephony system which is generally referred to as the cellular telephone network
  • Such arrangements are also used for the purpose of indicating the theft or attempted theft of the vehicle to the owner by placing a call to the owner upon the detection of an intrusion into the vehicle by an unauthorised person
  • Such systems are detailed in the prior art in various specifications including US4825457 (Lebowitz), US4905271 (Namekawa), US5081667 (D ⁇ o ⁇ ), US4718080 (Serrano) and US5370201 (Inubushi) In all of these specifications, cellular transceivers are used for control and status reporting of the vehicle
  • transceiver devices Whilst such systems provide very useful functionality, there is a demand for devices and systems of lesser complexity and lower cost Systems that comprise a transceiver device generally retain the capability to be used for voice communication so that users may utilise all the functionality of the transceiver device This is generally achieved by retaining the transceiver in relatively close proximity to the driver
  • a security system it is disadvantageous to have components of the system visible to potential thieves Any component of a security system that is visible is vulnerable to attack or tampering and is hence best avoided Consequently, in an attempt to reduce complexity and cost, there have been various alternative systems that have been proposed that incorporate a receiver only and these systems generally employ a paging device
  • These systems comprise a significant cost advantage over transceiver based systems and as a result, can generally be installed in a secluded part of the vehicle as the receiver is limited to the single purpose of acting to receive an immobilisation command from an owner It is highly desirable to incorporate a paging device into a switching apparatus with minimal re-configuration or adaptation to
  • a significant disadvantage of a receiver only based system is a consequent reduction in the certainty of signal reception
  • Transceiver based systems that are capable of transmitting signals back to the owner can report the status of the vehicle thereby giving the owner certainty that the vehicle has been immobilised.
  • Receiver only based systems cannot provide this feedback and hence fall into a class of systems referred to as "open loop" control systems. Accordingly, with receiver only systems, the certainty of the correct signal being transmitted is paramount to the correct operation of the system.
  • Paging systems are generally operated by a central receiving agency that can be contacted by any telephone that can communicate with the public telephone system Upon calling the central agency, an operator requests the number of the pager to which the caller wishes to send a message and upon detailing the message to the operator, the message is transmitted to the appropriate pager
  • the transmission of the message to the pager may be by various means including land based transmission systems or satellite means
  • Other specifications detail the method of detecting transmitted codewords to a pager unit by detecting the varying electromagnetic flux associated with an audio speaker which is contained within the pager All of the disclosed methods are generally considered to be unreliable and are considered by many to be sufficiently unreliable to incorporate into an "open loop" vehicle immobilising system.
  • the other type of system avoids the complexity of the vehicle based apparatus and the requirement of such apparatus to extract codes and store and compare codes by not requiring the transmission of a security code and hence will disable the vehicle upon reception of a "calling" signal only to the paging unit.
  • This approach significantly increases the confidence that a signal that is transmitted is received and hence the switching effected
  • a significant disadvantage of such systems is the increased likelihood of such systems being abused by users placing calls to the pager unit without appropriate authority and an increased likelihood of human error in placing a call to an incorrect pager and hence resulting in vehicles being disabled when such an action was not intended
  • this invention also simplifies the process of performing a switching operation
  • the remote switching service is based upon each subscriber being assigned a unique call connection number such that calls connected to the service inherently identify the subscriber and hence obviates the requirement for separate identification of the remote switching apparatus that the user wishes to activate
  • the invention also comprises automated verbal instructions to guide users through the process of performing a switching operation
  • this invention is also useful for remotely disabling other devices such as televisions, radio sets, refrigerators, freezers and similar electrically powered devices Such use could extend to a rental agency wishing to be able to disable such devices if accounts are not duly paid and enable reconnection of the device upon payment of the account Likewise, this invention may also be used by a vehicle rental agency wishing to disable any vehicle that has not been returned at the prearranged time and place As was also previously highlighted, the ability to remotely disable these types of devices would deter many thieves from stealing the equipment

  • a remotely activated switching system wherein a remote switching apparatus comprises a receiving means but not a transmitting means and said signal transmitted to said remote switching apparatus comprises a calling signal only and does not comprise any information relating to the authority of the user to activate said remote switching apparatus
  • a remotely activated switching system wherein a remote switching apparatus comprises a switching means operatively connected to the device to be remotely switched, such that operation of the switching means either enables or disables a supply of energy to the device, and that upon transmission of an activation signal to the remote switching apparatus said switching means residing in its initial state is actuated to occupy its opposite state such that energy is either supplied or restricted to the device

  • the system further comprises remote switching apparatus that is located in close vicinity to, and preferably within, the device that the user wishes to be able to remotely control
  • Said remote switching apparatus comprises a receiving means and a switching mechanism electrically interconnected such that upon the receiving means receiving an appropriate signal the switching mechanism is activated
  • the remote switching apparatus comprises a pager which can be uniquely identified and signalled
  • Each remote switching apparatus is assigned a security code that the user must be able to transmit at the time of requesting activation of the remote switching mechanism
  • the computer means also comprises a database of numbers corresponding to remote switching apparatus and corresponding security codes If the correct security code is transmitted by the user to the computer means then the computer means will confirm the authority of the user to activate the switching mechanism and request confirmation that the user wishes to proceed by pressing a specific key on the handset keypad Upon depressing that key, the computer means will then initiate transmission of a calling signal only to the remote switching apparatus Receipt of a calling signal by the remote switching apparatus then activates the switching mechanism
  • the system also embodies many other advantages over prior art systems in that upon noticing that a device has been stolen, most people tend to be emotionally upset and thereby do not operate equipment as efficiently and effectively as they normally would
  • this invention enables users to be guided through the process of remote switching of their device with minimal information required to be supplied thereby alleviating the level of concentration and memorisation of the steps required to activate the remote switching apparatus
  • the computer means enables the operation of the system without the requirement of human intervention or operator assistance This also extends to the maintenance of security codes for individual users as the software program can enable the computer to enable users to maintain the database of remote switching apparatus and security codes for individual devices Certain users may wish to have the same security code for all the devices for which they have a remote switching apparatus fitted In extending this concept further, a user may wish to be presented with a voice menu of devices that may be switched upon calling the computer and hence could choose from a menu of devices to switch and then provide the security code to enable the chosen device to be remotely switched
