A system, device and method monitoring whether a core temperature of a warm-blooded pet animal is within a normal range for the pet animal comprises a sensing assembly including (i) a skin temperature sensor positioned such that a sensing surface of the skin temperature sensor faces the animal, the skin temperature sensor configured to produce a skin temperature output, (ii) an ambient temperature sensor spaced away from the animal and configured to produce an ambient temperature output, and (iii) an accelerometer for sensing an acceleration of the pet animal and producing an acceleration output; and a processor for receiving the outputs, calculating an activity level from the acceleration data and determining whether the core temperature of the pet animal is within the normal range based on a pre-defined function relating the skin temperature T, the ambient temperature T, and the activity level of the pet animal.

The Very Light Readers of the present invention are based on an augmented Tag circuit with a preferred embodiment including at least one VLSI chip integrating a UWB front end, digital transceiver, and possibly an internal controller; a UWB Antenna; a power supply; a controller configured to implement the Media Access Control protocol of the system; a Communication Interface subsystem for connection to the system network and a clock source. Also described is a system capable of reducing collision occurrence in a network for communicating between multiple readers and a plurality of RF Tags. Tags are configured to receive interrogation signals and transmit response signals. Readers are configured to transmit interrogation signals, receive response signals, estimate the quantity of responses received to an interrogation, determine the round trip delay time of each response and estimates whether a collision between responses has occurred. If so, the Reader transmits an additional interrogation signal. The Reader also transmits an acknowledgment packet to responding Tags so responding Tag will not answer again to that broadcast session. Other Readers in the network also receive the acknowledge packet and do not try again to reach the responding Tags, thereby lowering congestion directed toward Tags from multiple Reader transmissions.
