Description

<Desc/Clms Page number 1>
ANIMAL ACCESS SYSTEM The present invention relates to an animal access system and in particular to a pet access validation system comprising identification means carried beneath the outer surface of the skin of the pet animal.
Known pet access systems that allow only certain pets to enter a premises include a door, an electrically operated door lock that is activated by a sensor and a fairly large magnet attached to a collar around the neck of the pet. We have found that these collars and magnets can be heavy and cumbersome. Many owners are reluctant to use the collars with magnets as they consider them an unacceptable risk because their pet may become entrapped or caught by their collar. In addition, because of the size of the collar and magnet they may be inappropriate for a smaller animal. Some owners are not willing to use them because of the appearance of the collars.
According to a first aspect of the present invention there is provided an animal access system comprising an access door, sensor means and an implant, the arrangement being such that in use the implant is inserted through the outer tissue of an animal, the implant being detectable by the sensor means.

<Desc/Clms Page number 4>
The animal access system may comprises movement detection means for detecting movement of a body within the locality of the access door, the arrangement being such that in use the sensor means is activated in response to the movement detection means detecting a moving body.
According to a second aspect of the present invention there is provided a method of controlling animal access using an animal access system comprising an access door, the method comprising firstly storing an animal identity code on the system, secondly detecting an identity code of an implant carried by an animal, thirdly comparing the detected identity code with the stored identity code and fourthly allowing access through the access door if the detected identity code matches the stored code.
In an embodiment of the present invention the method comprises firstly storing a plurality of animal identity codes on the system, secondly detecting an identity code of an implant carried by an animal, thirdly comparing the detected identity code with the stored identity codes and fourthly allowing access through the access door if the detected identity code matches one of the stored codes.
In a further embodiment of the present invention the method comprises storing a number of time periods on the system within which access is allowed and comparing the time of the detection of the identity code with the stored time periods and allowing access through the access door if the time of the detection is within one of the stored time periods.
In a further embodiment of the present invention the animal access system comprises a light intensity measuring device, the method comprising storing a predefined light intensity range on the system within which access is allowed and measuring the external light intensity and allowing
<Desc/Clms Page number 5>
access through the access door if the external light intensity is within the predefined range.
The present invention may include any combination of the features or limitations referred to herein.
The present invention may be carried into practice in various ways, but two embodiments will now be described by way of example only with reference to the accompanying drawings in which : Figure 1 is a cross section view of an animal access assembly for providing access through a door ; Figure 2 is an elevation view of an inside portion of the animal access assembly shown in Figure 1 ; Figure 3 is an elevation view of an outside portion of the animal access assembly shown in Figures 1 and 2 ; Figure 4 is a cross section view of an animal access assembly for providing access through a wall section ; Figure 5 is an elevation view of an inside portion of the animal access assembly shown in Figure 4 ; and Figure 6 is an elevation view of an outside portion of the animal access assembly shown in Figures 4 and 5.
Referring to the Figures 1 to 3, an animal access system comprising an access door assembly 1 comprising an access door 2, locking means 8 for the access door 2, an implant 6, sensor means 4 for detecting the implant
<Desc/Clms Page number 6>
6, and a computer management unit 10. The animal access system provides controlled access through a hole 11 formed in a door 12.
The implant 6 is located beneath the outer layer of skin of a pet animal 15. Conveniently the implant 6 is a microchip encased in a suitable material. Known microchips are presently used for identification purposes on small pet animals, such as cats and dogs. One type of microchip is a FDX-B microchip, where scanned information is sent from the chip to a handheld reader. Such microchips are normally sited in the scruff of the neck of the animal. The present identification microchips are used for the UK passports for pets scheme.
The sensor means 4 comprises a microchip reader 16 that is housed within an upper section 13 of a canopy 14. The microchip reader 16 is located distant from the access door 2 and projects in a direction outwards from the door 2. The microchip reader 16 is connected to the computer management unit 10. As the animal 15 approaches the access door 2 the implant 6, which is sited in the scruff of the neck of the animal 15. passes underneath the microchip reader 16. The microchip reader 16 receives the identification code from the implant 6 and sends this information to the management unit 10.
The canopy 14 comprises the upper section 13 and two side sections 18, 20. The sections 13, 18 and 20 each extend outwardly from a first frame portion 21. The first frame portion 21 comprises a flange 23 that extends in a direction away from the canopy 14 and into the hole 11 formed in the door 12. The access door 2 is pivotally attached to an upper region of the first frame portion 21 by a pivot assembly 25.
<Desc/Clms Page number 7>
The canopy 14 helps to protect the access door 2 and sensor means 4 from elements of the weather, and helps to channel the animal 15 underneath the sensor means 4. The canopy 14 may comprise a solar panel of photoelectric cells 22 for the generation of electrical power.
The electrical power may used directly by the animal access assembly 1 or the power maybe stored in a battery for future use by the animal access assembly 1. The size of the canopy 14 is preferably in direct proportion to the size of the access door 2 and so to the size of the pet concerned.
Disposed on the inside of the door 12 there is a second frame portion 26.
The second frame portion 26 comprises a flange 28 that extends in a direction towards the canopy 14 and into the hole 11 formed in the door 12. In the assembled state a portion of the flange 23 is received by the flange 28. The two flanges 23, 28 are held together by a screw 29. The amount by which the flange 23 extends along the flange 28 depends on the thickness of the door 12. It should be appreciated that the arrangement of the first and second frame portions 21 and 26 is adjustable such that different thickness of doors can be accommodated.
The computer management unit 10 is located at an upper region of the second frame portion 26. The unit 10 comprises a visual display screen 30 and an array of action keys 32. The computer management unit 10 is provided with power via an electrical wire 34. In use the identification code of an implant 6 can be stored in the unit 10 either by scanning the implant 6 using the sensor means 4 or by manually entering the code using the action keys 32. The action keys 32 may be used to input time periods within which the access door 2 may be opened.
<Desc/Clms Page number 8>
The microchip technology used may be most conveniently that accepted by the International Standards Organisation (ISO) covering both the identification codes (ISO 11784) and the technology for the microchip and reader (ISO 11785).
The locking means 8 of the animal access system comprises an electronic solenoid mechanism 40 and a manually operated locking mechanism 42. The electronic solenoid mechanism 40 is controlled by the computer management unit 10. The electronic solenoid mechanism 40 has a first condition wherein the access door 2 is prevented from opening and a second condition wherein the access door 2 may open.
The manually operated locking mechanism 42 comprises an external knob 44 disposed at one end of a shaft 46 and two disc shaped members 48,49 attached to the shaft 46 either side of the access door 2. The knob 44 is used to rotate the shaft 46 and members 48, 49 in order to lock or unlock the access door 2. The member 48 prevents the access door 2 being pushed outwardly in a direction towards the canopy 14 by being rotated to face the access door 2. The member 49 prevents the access door 2 being pushed inwardly by being rotated to face the access door 2. The locking means 8 may be used to completely lock the access door 2 ; or to allow the access door 2 to be only pushed inwardly; or to allow the access door 2 to be push outwardly; or to allow the access door to be pushed inwardly and outwardly.
There are two potential strategies in relation to the locking means 8: 1. The manually operated locking mechanism 42 may be used to allow complete the access; or to lock the access door 2 completely ; or to allow access inwardly only or allow access outwardly only.
<Desc/Clms Page number 9>
2. The electronic solenoid mechanism 40 may be used to completely lock the access door 2; or to allow the access door 2 to be opened inwardly or outwardly.
The computer management unit 10 may be programmed to store and recognise individual implants by either one of the following strategies: 1. The first strategy is where the action keys 32 are used to enter various identification codes of implants into the unit 10, which may be verified using the display screen 30. This approach will provide flexibility to allow codes to be changed or deleted. The action keys 32 may be used to enter the time periods within which access is allowed. The time periods of allowable access may be specific to a particular identification code and hence to an individual animal.
2. The second strategy would require only one key to be activated when an implant in an animal is held under the sensor means whereby the identification code is detected and then recorded.
With reference to Figures 4 to 6, there is shown a further embodiment of an animal access system comprising an access door assembly 50 that provides controlled access through a hole 52 formed in a wall section 54.
Many feature of this embodiment are substantially the same as the system shown in Figures 1 to 3 and the same reference numbers have been used to identify such features.
However, in this embodiment the canopy 24 extends through the hole 52.
The access door 2 is disposed in a mid region of the canopy 14 and is attached there to by a pivot 25. The sensor means 4 of the animal access assembly 50 comprises two microchip readers 16 disposed each side of
<Desc/Clms Page number 10>
the access door 2. Both of the microchip readers 16a, 16b are linked to the computer management unit 10.
The animal access assembly 50 operates in a substantially similar way as the animal access assembly 1. However, it will be appreciated that with the additional reader 16a an implant within an animal can be scanned by the system 52 when the animal attempts to leave a premises. The locking means 4 of the animal access assembly 50 comprises two electronic solenoid mechanisms 40a, 40b disposed each side of the access door 2.
The electronic solenoid mechanisms 40a, 40b may be activated together or independently.
In an embodiment of the present invention the access door assembly 1 may comprise a light intensity sensor, such as a photoelectric meter, that is in communication with the management unit 10. The management unit 10 may be programmed with a range of light intensity levels within which access is allowable. In use the light intensity sensor would monitor the external light levels and send this information to the management unit 10.
The management unit 10 could be programmed to only activate the system when the external light intensity is within certain limits. The owner of the animal 15 may decide to restrict access through the access door 2, for example the owner may only want the animal 15 to go outside when there is daylight outside.
It will also be appreciated that the programming of the computer management unit 10 could include different combinations of time periods and/or light intensity ranges within which the microchip reader 16 is activated. Alternatively, the programming of the computer management unit 10 could include different combinations of time periods and/or light intensity ranges within which either electronic solenoid mechanisms 40a
<Desc/Clms Page number 11>
40b maybe activated following the detection of an implant by either of the readers 16a, 16b.
The access door assembly 1 may comprise a proximity sensor for detecting an approaching animal 15, the proximity sensor being in communication with the management unit 10. In use the microchip reader 16 is activated following a detection signal from the proximity sensor.
