The present invention relates to an improved animal collar assembly that is particularly, but not exclusively, well suited to pet animals such as dogs and cats.
Any references to methods, apparatus or documents of the prior art are not to be taken as constituting any evidence or admission that they formed, or form part of the common general knowledge.
When animals, including pets such as dogs and cats, are unwell, early detection is difficult for pet owners. Whilst it is standard veterinary practice to check for the animal's vital signs such as heart rate, blood pressure and pulse, such checks are only carried out when the animal has become very sick and presented to the vet. Early detection is often not achieved yet is very important in order to achieve less suffering of the pet and less likelihood of a severe disease, which can develop if detection occurs late. Whilst many smart animal collars are currently known, most of these collars detect movements or require contacting probes to analyse animal health. Since most animals have a lot of fur, contact based electronic probes in animal collars have been generally unreliable. Therefore, there is a need to provide an improved animal collar that addresses some of the deficiencies of the prior art.
In an aspect, the invention provides an animal collar assembly for monitoring an animal's behaviour and/or an animal's health, the collar including an electronic module including a housing for enclosing electronic componentry therein, the electronic module including a first coupling arrangement for coupling to a collar strap adapted to be passed around a neck region of an animal, and the collar strap including one or more radio frequency sensor arrays.

Preferred features, embodiments and variations of the invention may be discerned from the following Detailed Description which provides sufficient information for those skilled in the art to perform the invention. The Detailed Description is not to be regarded as limiting the scope of the preceding Summary of the Invention in any way. The Detailed Description will make reference to a number of drawings as follows:
The collar assembly 100 includes a flexible strap 110 that can be passed around the animal's neck region and suitably tightened. The strap may be made from any suitable synthetic or natural material such as nylon or leather and formed as a continuous loop. Alternatively, a buckle such as buckle 112 may also be provided to fasten two ends of the strap 110 together to achieve a closed configuration. The collar assembly 100 includes an electronic module 120 which is coupled to the strap 110 via a coupling arrangement.
The flexible strap 110 includes a plurality of radio frequency sensor arrays 10. Each sensor array includes of a radio frequency (RF) transmitter 12 and a radio frequency (RF) receiver 14 best shown in
It is envisioned that the RF sensor transmitters 12 can dynamically improve the signal quality of signal datasets received by the RF receivers 14 for use in determining cardiovascular data. In order to continuously update parameters, a delay module 16 may be arranged in connection with the sensor arrays 10 for delaying signals, delay line settings, weighting parameters and control any other parameters affecting signal quality before, during, and/or after sessions of RF sensor 10 activity (e.g., transmission of incident signals towards an artery of the user, receipt of reflected signals, etc.). It should be understood that the sensor arrays 10 may be modified or configured to accommodate for variables affecting consistent signal quality, including user variations (e.g., different animal physiology, different motion, different ways of operating the RF system, etc.). RF system variations (e.g., different orientations of the RF sensor device, different arteries at which measurements are collected, etc.), and/or other variations.
The provision of a plurality of RF sensors 10 along the length of the collar strap 110 allows each sensor (or RF transmitter 12 and RF receiver 14 pair) to transmit and receive signals at different locations of an artery, and/or at different arteries. By way of a non-limiting example, a first RF sensor 10 may be used to collect reflected signals at a first location for an artery in the animal's neck and second RF sensor 10 may be used to collect reflected signals at a second location of the artery. Reflected signal datasets collected at different locations can then be used in evaluating body movement-related data (e.g., tissue movement-related data, respiration, heartbeat, arterial motion, stroke volume, pulse parameters such as pulse transit time and pulse wave velocity, etc.), from which cardiovascular parameters (e.g., heart beat metrics, blood pressure metrics, pulse rate metrics, physical activity metrics, metrics correlated with cardiovascular-related health, pulse oximetry metric, arterial metrics, respiration metrics, etc.) can be determined.
It is also envisioned that the RF sensors 10 may be capable of performing continuous monitoring of biometric parameters of the animal. For example, cardiovascular data such as heart rate, pulse and blood pressure data could be collected on a continuous basis with hundreds if not thousands of reflected signal datasets being generated every second. Alternatively, the RF sensors 10 could also be programmed to be dynamically triggered (e.g., in response to detecting an inactive user state based on motion data collected by other additional sensors 20 (such accelerometer type sensors as will be discussed in the foregoing sections).
Referring to
The RF sensor 10 may be preferably constructed with flexible materials to conform to the contour of the animal's neck region. It is also envisioned that these RF sensors 10, namely the electronic componentry may be encapsulated in a flexible material to allow the RF sensors 10 to better conform to the animal's contours. In alternative embodiments, rigid materials may also be used for constructing the RF sensor array 10.
Furthermore, one or more adjustment mechanisms may be used to control to control location of the sensor arrays 10 for positioning the radio frequency sensor arrays 10 to be located outside a reactive near-field with respect to the neck region of the animal. By way of example, a mechanism may be provided to fixing the distance between the RF sensors 10 and a target region of the animal's neck. In this regard, the buckle 112 may be utilised to ensure that the target neck region of the animal always lies outside the near-field of the RF transmitter 12 and RF receiver 14 pair.
Each of the RF sensors 10 is in communication with the processor 121 that is housed in the electronic module's housing 120. The processor 121 is also arranged to be in signal communication with a data transmitter 125 to transmit data or signals associated with processed reflected signals received by the RF sensors 10 in the collar strap 110. As shown best in
The coupling arrangement (best shown in
Turning to
During operation in the containment mode, the microprocessor (M/P) may receive sensory data from an array of additional sensors such as (but not limited to) S1 and S2 in communication with the microprocessor (M/P). The additional sensor array may include an accelerometer configured to measure at least one accelerometer-measured bioparameter of the animal from among: resting patterns, activity patterns, movement patterns, position patterns, noise and sound patterns, lameness and scratching, and the non-accelerometer sensor configured to measure at least one of the following non-accelerometer-measured bioparameters of the pet animal: temperature, pulse rate, respiration rate. The at least two sensor elements may includes at least three or at least four or at least five or at least six or at least seven (or more) sensor elements distributed at different locations within the electronic module housing 120. The on board microprocessor (M/P) may receive data values from the one or more sensors (S1, S2) of the additional sensor array and the RF sensor array 10 and compare these values with reference data to determine a likelihood of a specific health related condition in the animal and providing an indication of said likelihood on a display provided on the collar housing or on a remotely located device such as the docking station 200 or a remotely located device (such as a mobile computing device including a smartphone or tablet or any other computing device) in communication with said electronic module 120. In this regard, the remotely located device may communicate directly with the docking station 200 via the internet or any other communication network. In some instances, the on-board memory device (M) may include some reference values for comparison with data received from the sensors S1 and S2. In other scenarios, the sensor data may be transmitted to the docking station 200 via the transceiver (LTR) and comparative processing may be carried at a remote processing location by utilising a server or computers communicating with the docking station 200.
The docking station 200 may be used for updating the firmware installed on the microprocessor (M/P). The updates may be carried out by either transferring one or more update files from the docking station 200 whilst the electronic module 120 is docked on the docking station 200. Alternatively, or additionally, the updates from the docking station 200 may be transmitted to the electronic module 120 wirelessly.
The collar assembly 200 also includes a flexible strap 210 that can be passed around the animal's neck region and suitably tightened. The strap 210 may be made from any suitable synthetic or natural material and formed to be fastened and provide a continuous loop. A buckle 212 is provided to fasten two ends of the strap 210 together to achieve a closed configuration. The collar assembly 200 also includes an electronic module 220 which is fixedly coupled to the strap 210 at two ends of the housing 220 via a fixed coupling arrangement. The upper surface of the strap 210 includes a plurality of engagement portions 211 that are positioned in a spaced apart arrangement along the length of the strap segments 210A and 210B that may be engaged by the buckle 212 to form the closed loop. The plurality of engagement portions 211 may be formed integrally within the flexible strap 210 or alternatively may be embedded therewithin.
The flexible strap 210 also includes a plurality of the radio frequency sensor arrays 10 which have been described in the previous sections. Each sensor array 10 includes of a radio frequency (RF) transmitter 12 and a radio frequency (RF) receiver 14 best shown in the conceptual
Each RF sensor 10 located along the collar strap 210 transmits RF signals (e.g., incident pulse signals) towards the neck region of the animal and receives reflected signals for generating a reflected signal dataset. A signal modification module 16 may modify the reflected signal dataset. The electronic module 220 houses the processor 121 and the controller 123 that is arranged to be in communication with the RF sensors 10 and the signal modification module 16. The processor 121 and the controller 123 are arranged to generate biometric parameters such as but not limited to cardiovascular parameters for the animal based on the modified reflected signal dataset received by the RF receiver 14 for each RF sensor 10.
The RF sensors 10 are embedded within the thickness of the flexible strap 210 and preferably encapsulated in flexible material to better conform to the animal's contours. The plurality of RF sensors 10 in the strap segments 210A and 201B may be located at a desirable location adjacent a target physiological region of the animal's neck. The buckle 212 in combination with the engagement portions 211 allows for more precise positioning of the RF sensors 10 around the animal's neck region. Each of the RF sensors 10 is in communication with the processor 121 that is housed in the electronic module's housing 220. The processor 121 is also arranged to be in signal communication with the data transmitter 125 to transmit data or signals associated with processed reflected signals received by the RF sensor arrays 10 in the flexible strap 210. In the preferred embodiment, the RF sensors 10 in the strap segments 210A and 2104 are connected to the various components of the electronic module 220 by flexible and flattened conductors embedded within the collar strap segments 210A and 210B.
Once again, it is considered desirable if not ideal to maintain the location of the electronic module 220 behind (or above) the ears of the animal such that the electronic module 220 is substantially equidistant from each ear of the animal. The mounting location of the electronic module 220 is substantially maintained by providing a counterweight module which forms a part of the buckle 212. the counterweight buckle 212 is also coupled with the flexible strap 210 at a spaced apart location from the electronic module 220 in a manner such that during use, the counterweight buckle 212 is located along a ventral region of the animal's body. The counterweight buckle 212 either alone or in combination with additional counterweight bodies (not shown) forms a counterweight module 230 so that the counterweight module 230 has a weight that is at least substantially equal to or preferably greater than the weight of the electronic module 220 which causes the heavier counterweight buckle 212 to be maintained at a ventral region of the animal's body as a result of which the relatively lighter electronic module 220 remains behind the animal's ears along a dorsal portion of the animals' body even during prolonged periods of use. Maintaining the position of the electronic module 220 improves connectivity between data transmitters in the electronic module 220 and any satellites as will be explained in further detail. Therefore, providing the counterweight buckle 212 prevents the electronic module 220 from slipping towards a ventral region of the animal's body. The counterweight buckle module 230 may also be utilised for performing other secondary functions. In one useful embodiment, the counterweight module 230 may be provided with an outwardly visible surface to provide useful indicia such as (but not limited to) the animal's name to assist in correctly identifying the animal. Other useful information in relation to the pet animal's owner may also be provided on the outer surface of the counterweight module 230.
