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.

An electric fence energizer provides automated reporting of faults and other events as well as fault location to reduce effort in diagnosing faults and intrusion events in electric fences by measuring impedance changes using a time-domain reflectometer. In some embodiments, methods determine the location of a fault in distance from the energizer and provide timely and appropriate condition information.

An electric fence energiser is intended to reduce exposure of an animal tangled in the fence line to high power deterrent pulses for an indefinite period. The method of operating the electric fence includes sensing a characteristic associated with said evaluation pulse (s) that varies with load on the fence line, and set a threshold value (16) based on said sensed characteristic. This is proceeded by sending one or more further low power evaluation pulses along the fence line, sense a characteristic to the threshold value. When the sensed characteristic pulse (55) falls below the threshold value, indicative of an animal in contact with the fence line is detected, send one or more but not more than a predetermined maximum number of higher power deterrent pulses (56) along the fence line.

The TASER3 alternative (10) uses electronic stun capability in combination with a landmine housing (12) and deployment system. Although the TASER3 non-lethal area denial device (10) would cause no deaths or injuries if accidentally triggered by friendly forces, it can also be permanently disabled when no longer needed, by remotely using a secure code to shut down the TASER3 system. When triggered, the device (10) launches darts in multiple directions at 10 or 20 degree intervals in a direction generally facing the enemy. The darts temporarily incapacitate any persons within an inch of the darts by causing uncontrollable spasms of the near surface motor control muscles causing temporary loss of the subject's motor control functions. A timing circuit (37) keeps the subjects incapacitated until they can be taken into custody by nearby troops. After the very low power signal is turned off, the subject will recover in minutes. The device (10) may be remotely shut down permanently via an encrypted security code.
摘要:
In an electric fence energizer there is an exterior earth connection such as an earth connection post (16). The electric fence energizer comprises in the conventional way a transformer (T) having a primary winding (L1) and a secondary winding (L2), one exterior terminal (9) of which is connected to the conductor (17) in the electric fence and the other exterior terminal (11) is connected to the earth connection, high voltage pulses being induced over the secondary winding (L2) when voltage pulses are applied over the primary winding (L1). For a determination of the quality of the earth connection the voltage over a small part of the secondary winding is obtained capacitively by means of an extra winding (L3) in the transformer (T). For an evaluation of this voltage it is connected, only for a determined polarity, to a charging circuit for a capacitor (C2), which is discharged over a known resistor (R2, R3). The voltage (V21) over this capacitor (C2) is processed for a determination of the quality of the connection to earth. Then the time difference can be determined between the time (t0), when the induction is a high voltage pulse over the secondary winding (L2) starts, and the time (t1, t2), when a voltage change of the capacitively obtained signal after that starts and when the voltage returns to its stationary value. These time differences are compared to threshold values for determination of the quality of the connection to earth. The capacitively obtained voltage can also be used for other determinations in the electric fence energizer.
