  • Patent number: 6775337
    Abstract: Method processor and processor-readable medium for reducing the level of feedback-induced noise in the output signal from an audio automatic gain control circuit are provided. The method allows for receiving a stream of pulses comprising an input signal to the automatic gain control circuit. The method further allows for receiving estimates of respective high and low frequency energy components of the input signal. The respective high and low frequency components are averaged, e.g., over a respective sliding window. An energy scalar is calculated based on the ratio of a predefined target energy level over a combined value of the high and low frequency components. A relating action allows to compare the target energy level to the combined value of the high and low frequency components. Based on the comparison results, the calculated energy scalar is limited to within the two limit values.

  • Patent number: 6768905
    Abstract: Method and processor for determining loading of a communications system shared by a plurality of user-terminals are provided. The method allows a respective terminal for monitoring a control channel including logical messages therein. The monitoring of the messages in the control channel is performed regardless of whether or not the logical messages therein are specifically addressed to that terminal. The method further allows for estimating a parameter indicative of system loading based on information in the monitored logical messages.

  • Publication number: 20040113795
    Abstract: A battery-powered transmitter which emits an audible sound or RF signal, including a housing which is mountable to the collar for a pet, for example. The present device is switchable between “on” and “off” modes of operation by means of a rotary cap whose rotational position effects switching of the device between its “on” and “off” modes of operation. Tactile and visual indication of the then-current operational mode of the device is provided by means of the rotational position of the rotary cap and indicia provided on the housing of the device and on the rotary cap itself.

  • Publication number: 20040100039
    Abstract: A gasket sealing system for providing a gasket seal disposed between a lid removably connectable at a receiving module containing electrical circuitry and/or batteries. The lid includes a perimeter surface that is removably insertable against a rim bordering an opening into the module. A gasket is adapted to bond to the perimeter surface of the lid. The gasket includes a first contacting surface having an arcuate shape that deforms upon contact against the module rim. The gasket includes a bonding surface adapted to bond to the shape of the perimeter surface of the lid. The gasket is composed of a resilient material that is self-lubricating. When the lid is removed from the rim of the opening, the deformable gasket is disconnected from sealing against the rim of the module without disruption of the integrity of the gasket.

  • Patent number: 6668760
    Abstract: An apparatus for controlling the barking of a dog through application of a spray deterrent, or spray control bark collar. The spray control bark collar administers a dose of a pressurized substance in response to the barking of the dog. The spray control bark collar detects the barking of the dog through the measuring of vibrations produced by the dog. In addition, the spray control bark collar delivers successively larger doses of the spray deterrent to the dog to deter the dog from further barking should the dog fail to respond to previous deterrent attempts. Finally, the spray control bark collar monitors the usage of the spray deterrents to gauge the amount of the deterrent substance remaining in the deterrent substance reservoir.

  • Patent number: 6669419
    Abstract: A probe locking washer (10) for substantially preventing unwanted loosening of a probe mounted on a receiver unit of an animal training device in which the receiver unit is mounted on an animal collar. The probe locking washer (10) of the present invention includes a disk member (25) having an upper surface (30) and a lower surface (35) and a centrally disposed hole member (40) which allows the probe locking washer (10) to be mounted on the mounting post (20). The probe locking washer (10) also includes a countersink member (45) disposed in the lower surface (35) of the disk member (25) and which includes a plurality of internal radial spline teeth (50) for providing radial resistance to any untightening force caused by vibration or other untightening force.

  • Patent number: 6637376
    Abstract: An apparatus and method for producing a variable intensity static stimulation. The variable intensity static stimulation increases in intensity if the animal continues to require correction. By varying the duty cycle of a periodic signal having constant amplitude and a constant duration, the intensity of the static stimulation is varied.

  • Publication number: 20030167693
    Abstract: An apparatus for automatically actuating and securing a door has been shown and described. The automatic door system non-destructively retrofits a conventional door to allow actuation of the door. The automatic door system integrates a lock mechanism and a door actuation mechanism. The automatic door system allows hands-free operation and is suitable for use with pets or humans. The automatic door system controls the arc of the door swing and duration that the door remains open based upon the requestor activating the automatic door system. The automatic door system provides additional security over traditional mechanical locks. Further, the automatic door system allows access profiles to be customized to the requestor.

  • Patent number: 6588376
    Abstract: In a device adapted to dissuade a dog from barking, there is provided a reservoir of spray material associated with a collar which encircles the dog's neck. The reservoir includes at least one wall member defining an interior volume for the receipt of spray material therein. The reservoir includes a first dimension (i.e., a centerline) which lies within the median sagittal plane of an erect dog which is facing forward, thereby orienting one portion of the interior of the reservoir vertically lowermost. An exit port is provided for the transport of spray material from the interior to the exterior of the reservoir. A semi-rigid, lengthwise substantially non-compressible, conduit having a first end thereof connected in fluid flow communication with the exit port, extends from the exit port and terminates at its opposite and open end at the vertically lowermost interior portion of the reservoir when the present appliance is mounted at a location on the collar beneath the lower jaw of the dog.
