Description

INTRODUCTION

The present invention preferably seeks to describe as a non-limiting objective an electrically operable system to facilitate the use of keys for use with locks. The preferred keys for use with the invention are keys that include a mechanical key component. Mechanical keys are preferably those keys with one at least shapes formed onto one at least surfaces and/or edges of the key, said shape(s) preferably being essential to the operation of the target lock(s). Said essential formed shapes preferably distinguish said mechanical key from an electronic key where electrically readable stored content (for example, on magnetic strip and/or in semiconductor memory) coupled to said electronic key provides the essential information for operating the associated lock, even though the electronic information may be coupled an apparatus (eg credit card shape and size plastic apparatus) that needs to be a particular shape to couple with the electronics of the target lock. The invention seeks to expand on the means described in co-pending PCT AU03/001029, Titled “Identification and selection of keys for use with locks” by the present inventors. This document is incorporated into this specification by way of reference. The numbering used in the drawings of the present specification are not necessarily the same as those used in PCT AU03/001029.

DESCRIPTION

Co-pending PCT AU03/001029 describes a method of attaching an electrically readable Key ID device to a mechanical key, said device including an electrically operable indicator device, for example, LED. As a non-limiting example, when the key is attached to a key grouping device the activation of the indicator (eg illuminating said LED) is preferably used to facilitate user selection of the associated key from other keys that may be attached to the key grouping device. In this arrangement the indicator is clearly associated with the key by way of physical attachment, even when the key is removed from the key grouping device. The indicator of PCT AU03/001029 is preferably operable only when the key ID device is attached to the key grouping device, although allowance is made for an optional embodiment that incorporates power and control means into the Key ID device. Preferred methods of providing an electrically readable ID include one at least of a) RFID Transponder (for a solution that does not require an electrical connection to access digital information stored by said transponder) and/or b) an electronic device that operates using an electrical conductor for ground and at least a second electrical conductor that provides for the transfer of power, control information and data on a single conductor (for example Dallas Semiconductors ‘One Wire’ devices eg Dallas DS2401 Silicon Serial Number). The preceding examples provide a plurality of bits of digitally stored information that preferably may be used to provide part at least of a Key ID, such that a first digital ID attached to a first key is different to a second digital ID attached to a second key (and preferably different to a large number of other digital key ID's, that are preferably different to each other). The key ID device of PCT AU03/001029 preferably allows for indicia to be provided on an external surface of the key ID device, for example a bar code reader may be used to read a bar code on at least one surface of a key ID device. The key ID device of PCT AU03/001029 preferably allows for human readable indicia to be provided on one at least external surfaces of a key ID device.

To facilitate user determination of information pertaining to the lock(s) operable by a known KIDS, it is preferable that information stored by said KIDS is provided to an electrically operable device that has access to lock and key ID information previously stored in computer readable media. Said provision of Key ID Device information preferably may use any of the means described in the present specification and/or PCT AU03/001029 incorporated by reference.

• • Said information provided is preferably processed by an electrically operable device to determine if information pertaining to said key and/or the lock(s) operable by said key(s) have previously been stored in computer readable media coupled to said electrically operable device.
    • a) The user is preferably advised (eg display and/or speaker means, illumination of one at least LED's in one at least colours) if said previously stored Key ID information is not accessible to said electrically operable device.
    • b) If the Key ID information is accessible to said electrically operable device and said previously stored Lock information is not accessible, the user is preferably advised (eg display and/or speaker means, illumination of one at least LED's in one at least colours).
    • c) If said previously stored Key and Lock ID information are both accessible to said electrically operable device, the user is preferably provided with information facilitating determination of the target lock(s) of said key (eg display means and/or speaker means describing the location of one at least target lock and/or one at least objects associated with said lock).

When a keys is to be attached to a Key Grouping Devices it is preferable that an electrically operable device may determine the electronic address of one at least indicator devices to be associated (eg by attaching the key in the vicinity of said indicator device) with said key and the appropriated indicator device(s) are preferably activated (eg LED(s) switched on). The invention preferably allows that an indicator device that illuminates when active may be caused to emit a first colour at a first instant and second colour at a second instant, and/or a third colour at a third instant, and/or a fourth colour at a fourth instant. It is preferably that an illuminable indicator device that is to be associated with a particular KIDS, illuminates in a colour that approximates at least the colour of one at least shapes (preferably the primary coloured shape) of said KIDS.

• • Said illumination preferably may be automatic (eg. using database of unused locations) and/or under user control (eg user may enter one at least key board commands to sequentially illuminate one at least Indicator devices, until the desired Indicator device is illuminated). The user preferably attaches the key to the KGD such that a reasonable human observer should be able to associate said key with said illuminable indicator(s) in preference to one at least other indicators attached to said KGD. The user preferably confirms (eg keyboard entry) that said key has been coupled to said KGD. The address of said Indicator Means is preferably associated with said KIDS in memory storage means accessible to said KDG. This information preferably may be edited subsequently.

When a user wants to determine the correct key to operate a selected lock(s) and said key is attached to (or thought to be attached) to a KGD that is also attached to one at least other keys that may not operate said lock(s), the invention preferably allows for the user to enter information associated with said lock into an electrically operable device associated with said KDG, preferably using part at least of the method and apparatus described in this specification and/or PCT AU03/001029 (eg RFID, Onewire, Digital Camera to read indicia). The user preferably may provide descriptive information pertaining to the lock (eg “Front door of 36 Smith St, Somewhere”). Said descriptive information preferably may include text and/or voice as non-limiting examples. The user preferably may select text and/or pictorial information presented on an electronic display to provide information about the lock they are seeking a key for (eg, a. scroll through a list of descriptive text and select appropriate description, and/or b. view images (eg car, filing cabinet, cash box)). Said associated electrically operable device preferably examines previously stored electrically accessible information to determine if said Lock information has previously been stored and if information (eg Key ID information) pertaining to one at least keys that may operate said lock has previously been stored. If the Lock ID information is not accessible the user is preferably advised (eg display and/or speaker means). The user preferably may be given the opportunity to enter information about one at least keys that may operate the lock coupled to said Lock ID. For example a user may visually scan keys coupled to one at least user accessible KGD and determine if a suitable key is attached. If no key is present they preferably may terminate the process (eg keyboard entry). If at least one appropriate key is coupled to one at least user accessible KGD, the user preferably may cause the KGD to illuminate (for example) the indicator means associated with the appropriate key(s). The Lock ID and Key ID means are then preferably electronically associated with one another in memory storage means. If one at least appropriate user accessible keys are not presently attached to one at least KGD, the user preferably may be able to activate the relevant processes to enter Key ID information into one at least KGD (if not previously entered) and preferably associate it with the previously scanned Lock ID information. If Lock ID information has previously been programmed into said KGD and/or coupled electrically operable device, and the Key ID information is not accessible, the user is preferably advised (eg display and/or speaker means). The user preferably may be provided the opportunity of entering the relevant key information and/or attaching said key to one at least KGD. If the Key ID and Lock ID information are both accessible to one at least KGD and/or coupled electrically operable device, the user is preferably provided with information facilitating determination of the relevant key. The preferred means with the present example is to illuminate the indicator device associated with the appropriate key. The invention preferably allows that plural indicator devices may be use to define a particular associated key, for example a key(s) may be attached to a KGD between a first and second indicator device and the illumination of both devices is a user signal that one at least of said keys is the correct key. The invention preferably allows that plural keys, each with indicia distinct to one at least others of said plurality (eg first key has red primary coloured area, second has green primary coloured area, third has orange primary coloured area, fourth has yellow primary coloured area) may be concurrently associated with one at least indicator devices, said indicator devices preferably able to illuminate differentially to select a particular key(s) with a particular indicia (eg illuminates red if the KIDS with a red primary colour is to be selected, green for a green primary coloured area KIDS, orange for an orange primary coloured KIDS and yellow for a yellow primary coloured KIDS. The invention preferably allows that the use of this type of indicator device may be considered to represent plural indicator devices in the one device—as a non-limiting preferred example:—when red is illuminated, said indicator device is acting as a First Indicator Device; when green is illuminated, said indicator device is acting as a Second Indicator Device; when orange is illuminated, said indicator device is acting as a Third Indicator Device, and when yellow is illuminated, said indicator device is acting as a Fourth Indicator Device.

The invention preferably allows for the use of key ID devices with human readable indicia as described in this specification that do not include an electronic device.

Said AU 03/01029 describes means for password protecting access to one at least functions of one at least electrically operable devices described by the invention eg KGD. The present invention preferably allows for a Password Protection Means dependent on the presence of one at least First Electronic Means (eg electronics attached to said KGD ) and one at least Second Electronic Means (eg Wristwatch), wherein one at least means of communication between said Second Means and said First means is preferably restricted in the normal course of use of both means, and said First and Second Means preferably may communicate to facilitate access to restricted functions coupled to one at least First Means and/or Second Means. Said Second Means is preferably physically separate to said First Means and preferably unlikely to be misplaced concurrently with said First Means should said misplacement occur. A non-limiting example of said Second Means preferably may include a watch that is attached to an RFID transponder and/or Onewire device. As a non-limiting example, one at least KGD preferably may activate part at least of its functions (eg automated key selection) when said Second Means is coupled (eg close enough for RF communication in the case of said RFID transponder, in electrical contact in the case of said Onewire device) with said KGD if the required information (eg digital content) is provided to said First means from said Second Means.

It is preferable that one at least Password Activation Means may be required for one at least KGD (as a non-limiting example) to commence communication with one at least Second Means. As a non-limiting example of said Password Activation Means, the user may need to press one at least keys coupled to said KGD to enable the RFID Reader coupled to said KGD. The invention preferably allows that one at least means activated by one at least Password Activation Means may be terminated (as a non-limiting example, said RFID reader preferably may automatically time-out after a predetermined period).

As a non-limiting example of a means for a user to enter information (eg a command) into electrically operable means described for the invention (eg KGD), the invention preferably allows for the length of time and/or number of times, one at least first electronic input and/or output means (eg RFID reader) may access (eg read) one at least second electronic input and/or output means (eg RFID transponder). This is referenced as Modulated Reader Input.
