Abstract:
A disclosed pulse generator is configured to detect a voltage waveform output to an electrified element. The pulse generator has a charge circuit, a fire control circuit, an output transformer, and an energizer processor. The charge circuit receives a voltage input from a power source. The fire control circuit receives an output voltage of the charge circuit. The output transformer transforms an output voltage of the fire control circuit into a higher voltage output and delivers the higher voltage output to an electrified element. The energizer processor receives instructions from a communications component, determines one or more waveform parameters based on the instructions, and controls the fire control circuit such that the output of the fire control circuit corresponds to the one or more waveform parameters.
Abstract:
A method for controlling discharge of an electric stun device and an electric stun device. Status information is obtained from at least a second electric stun device via a wireless interface and a decision is taken, considering the status information, indicating if it is proper to discharge the electric stun device. An electric stun device comprising a wireless network interface capable of receiving authoritative information from at least another wireless device and a discharge control module that receives the authoritative information from the wireless network interface assesses whether the authoritative information indicates that the electric stun device is permitted to discharge.
Abstract:
A cartridge for propelling a pair of wire-tethered contact darts for disabling a remote target with an electrical discharge. The cartridge comprises two bores each having one wire-tethered dart in front of an electrically activated pyrotechnic. In order to avoid creating short arcing gaps after ignition of the pyrotechnics, the pyrotechnics are connected in electrical parallel with the wire-tethered darts so that current passing through the target does not have to arc across gaps left by the pyrotechnics. Two embodiments are presented, one in which the pyrotechnics are in series with the other and one in which they are in parallel relation to each other.
Abstract:
A cartridge for propelling a pair of wire-tethered contact darts for disabling a remote target with an electrical discharge. The cartridge comprises two bores each having one wire-tethered dart in front of an electrically activated pyrotechnic. A cartridge contains two separated straight bores, which each launch a single dart assemblage with a single primer of standard manufacture. A single 200 large rifle primer can launch a single dart assemblage reasonably accurately to 30 feet from the cartridge. Each assemblage is deflected to a predicted angle of flight when it collides with a center hinged cover as it exits the cartridge. This arrangement allows for longer flight distances and tighter, but still effective, dart spreads throughout the travel.
Abstract:
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.
Abstract:
The invention refers to a device for an electric fence. The device includes an electric unit (1) which is connectable to an electrically conducting fence (2) and which includes a voltage generator (4) arranged to apply a relatively high electric voltage to said fence (2). Furthermore, the device includes a proximity detector (5), which is arranged to sense a state at which an animal is at least in contact with or in the proximity of said fence (2), and a control unit (6), which is connected to the voltage generator (4) and the proximity detector (5) and arranged to activate the voltage generator (4) to apply said relatively high electric voltage to said fence (2) in response to said state. The proximity detector (5) is arranged to detect said state by sensing an electric parameter, which substantially depends on the capacitance between said fence (2) and ground.
Abstract:
The present invention relates to a remotely triggered improved electrical stimulus circuit to be worn by cattle which is lightweight and can store voltage lower than what is to be supplied to an animal. Known cattle electrical stimulus collars may be heavy, use a lot of energy, and not supply a consistent electrical stimulus. The present electrical stimulus circuit utilises feedback loops to allow the use of high tolerance lightweight capacitors, and/or cool down periods to utilise a highly inefficient transformer running fully saturated.
