An insulator is described the insulator comprising an insulator body having a front and back; a formation for supporting a barrier element; and at least one mounting formation having a front and a back by which the insulator is attached to a support, the back of the mounting formation in use being proximal to the support, at least one of the at least one mounting formation comprising: at least one passage extending transversely through the mounting formation from the front to the back of the mounting formation, at least one of the at least one passage being an arc slot.
An electric fence energizer including an IPC (isolated power coupling) power transmitter and an IPC power receiver adapted to receive power from the IPC power transmitter and supply power to the energizer. A pulse shaping circuit between an energy source and output transformer of the energizer may include a series inductance of between 2 μΗ to 20 μΗ and a parallel capacitance of between 3 μΡ to 30 μΡ. The energizer output transformer may comprise a primary winding consisting of less than 15 turns and a secondary winding of between 5 and 50 times the number of turns of the primary winding. The energizer may produce a pulse having a duration of between 20 με and 60 με and a peak amplitude greater than 5 kV into 300 Ω.
Systems and methods for determining the positions of animals and/or equipment in a farm setting. Individual animals may be associated with milking clusters or other equipment. Animal position may be determined using animal ID tags. Equipment position may be determined using one or more markers arranged on or near the equipment.

An electric fence connector having live engagement means and live attachment means and optionally isolated engagement means and isolated attachment means. The electric fence connector preferably has a maximum lateral dimension such as to allow it to pass through an aperture of an electric fence standard. In one aspect this may be achieved by longitudinally offsetting the live engagement means and isolated engagement means. The electric fence connector may be formed by injection moulding plastics material around a conductive element so as easily and inexpensively form a compact a rugged connector.
An oestrus detection tag includes a monitoring device and a body suitable to be secured to the back of an animal. The monitoring device has an exposed modifiable element, which changes in response to animal interaction with the modifiable element. A signal generated by the monitoring device is dependent upon the condition of the modifiable element.

A method of monitoring animals having RFID tags by downloading information associated with the IDs of the RFID tags to an RFID reader and displaying the information when an electronic ID is read or by accessing this information from a remote device via a wireless or wired link. Important information may require an acknowledgement before further processing can occur. The information may be workflow information requiring steps to be performed and data inputted in relation to multiple steps. The RFID reader may enable the display orientation to be selected based on user preference.

An electric fence system including a control module and a separate monitoring module and/or an energiser module. The provision of at least one wireless communication link between modules provides electrical isolation. Providing the energiser and monitoring module as separate units overcomes isolation requirements for combined energiser/monitors. The control module may display status information for associated modules based on status information communicated by the associated module. There is also disclosed methods of monitoring pulses applied to an electric fence and for controlling interference.

G08B 25/04 - Alarm systems in which the location of the alarm condition is signalled to a central station, e.g. fire or police telegraphic systems characterised by the transmission medium using a single signalling line, e.g. in a closed loop
H04B 13/00 - Transmission systems characterised by the medium used for transmission, not provided for in groups
A method of correlating identification information received from a portable electronic identification module arranged to interrogate an electronic identification device with information obtained from a monitoring device, the method including the steps of: positioning the module in proximity to the monitoring device at a testing station, reading the identification information using the module, wirelessly transmitting the identification information from the module to a central electronic control device, and correlating data from the monitoring device that is entered into the central electronic control device with the identification information.
G07C 1/10 - Registering, indicating, or recording the time of events or elapsed time, e.g. time-recorders for work people together with the recording, indicating or registering of other data, e.g. of signs of identity
