Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.
Detailed reference will now be made to several potential embodiment of the disclosure, which are illustrated in FIGS. 1 through 7.
The implantable pet locating microchip 100 (hereinafter invention) comprises a first housing 101, a battery 102, a location module 103, a thermal device 104, a gait sensor 105, a transceiver 106, a logic module 107 and an optional magnet 108.
The location module 103 is a tracking device that is used to determine the location of the invention 100. The location module 103 can be a GPS based device that determines the location of the invention 100 using the Global Positioning System.
The thermal device 104 is a device that is used to monitor the temperature of the pet 131. The thermal device 104 can be a thermistor or a resistance temperature detector. The resistance of either device will vary in a predictable manner in relation to the temperature of the device. By inserting the thermal device 104 into a voltage divider 109 circuit and applying a known voltage to the circuit, the temperature of the pet 131 can be determined by measuring the voltage 113 measured across the thermal device 104.
The gait sensor 105 is a device that is used to monitor the gait of the pet 131. To monitor the gait, the invention 100 is implanted into the pet 131 near the shoulder of the pet 131. From this position, the gait can be monitored using several methods. These methods include, but are not limited to, using a piezoelectric sensor or using a rotational angle sensor.
In a first potential embodiment of the disclosure, the gait sensor 105 uses a rotational angle sensor to monitor the pet's 131 gait. In this scenario, the gait sensor 105 comprises a Hall Effect sensor 110 and a magnet 108. The Hall Effect voltage 112 generated by the Hall Effect sensor 110 will be affected by the relative angle between the magnet 108 and the Hall Effect sensor 110. The magnet 108 used is a permanent bar magnet. The magnetic field generated by the bar magnet will not vary significantly with the gait of the pet 131. However, the position of the Hall Effect sensor 110 will vary with the gait of the pet 131. By measuring the change in the Hall Effect voltage 112, the gait of the pet 131 is monitored. In a first potential embodiment of the disclosure, the invention 100 is inserted into the animal along with a separate magnet 108.
In a second potential embodiment of the disclosure, the gait sensor 105 uses a piezoelectric sensor to monitor the pet's 131 gait. When force is applied to a piezoelectric sensor, a measurable static charge voltage is generated. The deformations in the piezoelectric sensor caused by the animals gait can be measured and recorded by the invention 100.
The purpose of the logic module 107 is to: 1) monitor the location of the invention 100; 2) monitor the temperature of the pet 131; 3) monitor the gait of the pet 131; 4) generate and transmit regularly scheduled messages regarding the location and well-being of the pet 131; 5) generate and transmit an alarm message should the thermal device 104 or gait sensor 105 readings meet predetermined criteria; 6) receive inbound communication initiating an ad hoc report; and, 7) generate and transmit an ad hoc report initiated by the inbound communication. Optionally, the logic module 107 can also be programmed to monitor the battery 102 and to transmit a signal when the battery 102 needs replacing. The logic module 107 is a programmable device that accepts digital and analog inputs, processes the digital and analog inputs according to previously stored instruction and to provide the results of these instructions as digital or analog outputs.
The transceiver 106 is a communication device that transmits outbound messages and receives inbound messages. The transceiver 106 routes inbound messages to the logic module 107 for processing. The logic module 107 also initiates the transceiver 106 to transmit a message and provides the contents of the message. The transceiver 106 can be a Bluetooth or 802.11 based device or can be a cellular device that transmits messages via text messaging (SMS) services.
The first housing 101 is a casing that encloses and protects the battery 102, location module 103, thermal device 104, the gait sensor 105, and the transmitter 106. The purpose of the battery 102 is to provide electrical power for use by the invention 100.
In a third potential embodiment of the invention 100, the invention 100 is not implanted but is mounted on a collar 132. In this embodiment, the first housing 101 is mounted directly on the collar 132 and, if used, a magnet 108 is mounted in a second housing 111 and placed on the collar 132. The thermal device 104 is replaced with a thermocouple that that is configured to measure the differential temperature between the pet 131 side of the collar 132 and ambient temperature. The battery 102 is configured with a USB micro port 112 to allow for programming of the logic module 107 and charging the battery 102.
To use the first potential and second potential embodiment of the invention 100, the logic module 107 and transceiver 106 are associated with the cell phone or other device that is designated to receive messages from the invention 100. This is done before surgery by sending a series of text messages with the required information. If a module needs to be programmed for a different device, this can also be done through a series of text messages. A similar functionality can be provided when other communication methods are used. The device is then implanted in the pet 131.
To use the third potential embodiment of the disclosure, the logic module 107 and transceiver 106 are associated with the cell phone or other device that is designated to receive messages from the invention 100. This can be done by uploading the information through the USB micro port 112. The collar 132 is then fitted on the pet 131.
In the first potential embodiment of the disclosure, a commercially available monolithic rotational sensor (EM3242 from DigiKey) is used. A commercially available GPS locator is used. A commercially available SMS chip is used as the transceiver. Alternatively, a combination GPS/GPRS can be used for the GPS locator and the transceiver. A microcontroller is used as the logic module 107. Batteries and housings suitable for implantation are well known and documented in the industry
