  • Patent number: 7819087
    Abstract: A remote controlled animal training system includes a wireless transmitter capable of transmitting a plurality of wireless signals non-concurrently. Each wireless signal of the plurality of signals is representative of one of a plurality of predetermined stimulus levels. A wireless receiver is capable of receiving the wireless signal from the transmitter. A demodulator is in communication with the RF receiver, demodulating the wireless signal to produce a digital signal. A microprocessor is in communication with the demodulator for receiving the digital signal from the demodulator and producing a pulse signal therefrom. A first output device is in communication with the microprocessor. The first output device produces a stimulus of intensity relative to a characteristic of the pulse signal.

  • Patent number: 7198009
    Abstract: An electronic apparatus (1) supported against a dog's skin to control vocalizing by the dog electronically converts the vocalizing into a sequence of signals representing frequencies of the vocalizing, and operates a controller to determine if each measured frequency lies within any of a plurality of predetermined frequency sub-ranges and if so, increments cumulative totals of the frequencies which lie in the sub-ranges, respectively, to provide a plurality of cumulative totals that represent a frequency spectrum of the vocalizing. The controller is operated to determine whether the barking sounds constitute a valid bark by comparing the frequency spectrum to a predetermined valid bark frequency spectrum. Appropriate aversive stimulus signals are produced between first and second stimulus electrodes if the vocalizing sounds constitute a valid bark.

  • Patent number: 7000570
    Abstract: An electronic apparatus (1) for training an animal is supported against the animal's skin, and includes stimulus electrodes (5) for electrically contacting the skin. A controller including output terminals producing aversive stimulus control signals, a first switch (Q4) coupled to a winding to produce therein a burst of first current pulses in response to a first signal produced by the controller (33) and a second switch (Q2) coupled to the first switch (Q4) operative to synchronously shunt predetermined trailing portions of the first current pulses away from the winding in response to a second signal produced by the controller to reduce the amount of energy delivered to the winding by the switching transistor (Q4) without substantially changing a peak value of a flyback voltage across the winding. The controller sets various values of time intervals during which portions of the first current pulses are shunted away from the winding in order to set various corresponding intensities of aversive stimulus.

  • Patent number: 6549133
    Abstract: A portable dog-training transmitter unit for controlling remote collar-mounted receiver/stimulus units includes first, second, and third switches for causing corresponding transmitted stimulus control signals to be recognized by corresponding first, second, or third receiver/stimulus units. A multiple-position switch sets the use of transmitted codes that control the amplitudes of stimulus signals produced by the recognizing receiver/stimulus unit. The transmitter unit is supported in a holster that is pivotally supported by a belt clip through the use of a pivot pin that is pivotally retained in a receiving slot of the belt clip. The transmitter unit includes a controller which polls the states of the various switches to produce a digital signal that is shaped by a buffer circuit, FM modulated, preamplified, and coupled by a simplified matching network to the input of a power amplifier. A single pi matching network is coupled to match an output of the power amplifier to an antenna of the transmitter unit.

  • Patent number: 6170439
    Abstract: An animal is trained using a remote transmitter and a collar-mounted receiver carried by the animal by selecting one of a plurality of desired stimulus levels by a stimulus level control of the transmitter. Information representative of the selected desired stimulus level is transmitted to the receiver and demodulated to produce a digital signal representative of the selected stimulus level. A microprocessor in the receiver operates to generate as an output a first stream of pulses of constant duration at a frequency representative of the selected stimulus level. The first stream of output pulses is filtered to produce a second stream of pulses the widths of which are representative of the selected stimulus level.

  • Patent number: 6061037
    Abstract: A flex antenna for a collar-mounted receiver-stimulator of an animal training device includes a conductive mounting element for connecting and disconnecting the flex antenna to and from a mounting connector of the receiver-stimulator. A flex conductor is connected between the conductive mounting element and a conductive coil support. An insulative rod is attached to the conductive coil support and supports an antenna coil having one end electrically connected to the conductive coil support. An insulative waterproof sheath is disposed on the entire flex antenna except an exposed portion of the conductive connecting/disconnecting structure. The sheath includes a cylindrical portion around the antenna coil and the conductive coil support and a portion of the diameter which gradually decreases from the first diameter to a second diameter and then increases to a third diameter. The second diameter is at a midpoint of the flex conductor to confine flexing to the midpoint.
