Abstract: Embodiments of the present invention are directed to a method and system for use of ranging MW to decrease MW intrusion detector false alarms. A Doppler microwave system may be provided that is capable of detecting an object range and adjusting the sensitivity of an alarm stage of a MW detector to account for object size and range. Multiple range limited MW stages may be configured for different ranges to determine the general range of the moving object. Based on signal levels present on these MW stages, an approximate object range may be determined. The sensitivity of the MW alarm stage is then adjusted based on a MW alarm state sensitivity vs. object range function that is optimized to alarm on humans and ignore small animals and insects. The method and system may be used in detection systems incorporating a MW sensor.

Abstract: Embodiments of the present invention is directed to a method and system for use of ranging MW to reduce dual (MW/PIR) intrusion detector false alarms. A Doppler microwave system may be provided that is capable of detecting an object range and adjusting the sensitivity of the PIR detector to account for object size and range. Multiple range limited MW stages may be configured for different ranges to determine the general range of the moving object. Based on signal levels present on these MW stages, an approximate object range is determined. The sensitivity of the PIR is then adjusted based on a PIR sensitivity vs. object range function that is optimized to alarm on humans and ignore small animals and insects.

Abstract: Embodiments of the present invention are directed to a method and system for use of ranging MW to detect range reduction in a dual (MW/PIR) intrusion detector. Embodiments of the invention utilize a Doppler microwave system capable of detecting an object range. Multiple range limited MW stages may be configured for different ranges to determine the general range of the moving object. Based on signal levels present on these MW stages, an approximate object range and size is determined. Embodiments of the invention recognize cases of PIR range reduction by use of range limited MW stages configured for different ranges to determine the general range of the moving object. If the MW recognizes a moving object of sufficient size within the coverage area, and if no PIR signal is present, the PIR is recognized as being blocked or disabled and notification is provided.

Abstract: The invention provides a novel method of vaccination of a pig against Mycoplasma hyopneumoniae by administering to a weaned piglet or a sow, a single dose of an effective amount of a Mycoplasma hyopneumoniae vaccine. The Mycoplasma hyopneumoniae vaccine can be a whole or partial cell inactivated or modified live preparation, a subunit vaccine, or a nucleic acid or DNA vaccine.
