The present invention discloses a method and apparatus for electronically deterring an animal from approaching an exclusion area around an exclusion unit or from entering or leaving an area bounded by a wire. The animal is provided with a collar unit, which includes a sensor adapted to sense the strength of electromagnetic signals generated by the exclusion unit or wire and a correction unit adapted to provide correction to the animal in response to a sensor output. The portable unit reports to a central controller which selects a correction strategy, such as level of correction to be applied to the animal approaching the perimeter. The controller provides warnings to the user, including warnings for when the battery in the collar unit goes low and when the animal stays in a correction zone for too long. The controller may control a number of exclusion units and/or power units, and may select an appropriate correction for one of a plurality of animals. The apparatus, with a central controller, may also be used to contain animals within one or more containment areas.

Minute Ventilation Sensor With Automatic High Pass Filter Adjustment
Dennis E. Larson - White Bear Township MN, US Douglas R. Daum - Oakdale MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
G01F001/00
US Classification:
702 45
Abstract:
A minute ventilation sensing device in which transthoracic impedance is measured to generate an impedance signal from which a ventilation signal is derived, where the ventilation signal is proportional to minute ventilation. An adaptive high pass filter is used to filter the impedance signal into a ventilation band. The pole frequency of the high pass filter is adjusted in accordance with changes in a calculated signal variation parameter.
Minute Ventilation Sensor With Dynamically Adjusted Excitation Current
Dennis E. Larson - White Bear Township MN, US Douglas R. Daum - Oakdale MN, US
Assignee:
Cardiac Pacemakers, Inc. - Saint Paul MN
International Classification:
A61N 1/365
US Classification:
607 17, 607 18, 607 24
Abstract:
A minute ventilation sensing device in which transthoracic impedance is measured with a excitation current waveform at a specified amplitude and frequency. In order reduce interference with the impedance measurement from external noise sources, a noise detection operation may be performed with the amplitude and/or frequency of the excitation current waveform adjusted accordingly.

Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N 1/36
US Classification:
607 30, 607 59, 607 32, 607 60
Abstract:
Systems and methods for telemetric communication between a handheld programmer and an implantable medical device are disclosed. A preferred embodiment comprises a user-friendly, color, touch-sensitive screen that allows the user to visually observe and control the handheld's operation. The handheld further comprises an internal and/or external analytical means to provide robust analytical capabilities. Some embodiments of a system disclosed herein can be configured as a component of an Advanced Patient Management System that helps better monitor, predict and manage chronic diseases.
Variable Antenna Matching Network For An Implantable Antenna
Dennis E. Larson - White Bear Lake MN, US Prashant Rawat - Blaine MN, US Daniel Kollmann - Andover MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N 1/375
US Classification:
607 36, 607 60, 343860
Abstract:
An implantable medical device may have an antenna for communication with external devices or other internal devices. Changes in the patient's body position, weight, composition or other factors may change the antenna efficiency and hinder communication. The disclosed circuit may automatically adjust a matching network for an implanted transceiver to dynamically maximize transmission and reception by controlling the selected value of a plurality of capacitors, inductors and resistors.
Variable Antenna Matching Network For An Implantable Antenna
Dennis E. Larson - White Bear Lake MN, US Prashant Rawat - Blaine MN, US Daniel Kollmann - Andover MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
H01Q 1/50
US Classification:
343861, 343860, 607 36, 607 60
Abstract:
An implantable medical device can include an implantable antenna for communication with external devices or other internal devices. Changes in the patient's body position, weight, composition or other factors may change the efficiency of the implantable antenna and hinder communication. The disclosed circuit can calculate a value for a matching network for an implantable telemetry circuit to decrease an impedance difference between the implantable telemetry circuit and the implantable antenna or increase or maximize a communication power transfer value associated with the implantable medical device.
