| 20090102665 | Wireless Tracking System And Method With Optical tag Removal Detection - A wireless tracking system and method with a tag removal detection feature is disclosed herein. The system and method utilize a tag attached to an asset which includes a processor, a motion sensor (such as an accelerometer), a transceiver, a tag removal sensor and a power source having a limited supply of power. The tag removal sensor is an optical sensor which is activated only when the motion sensor detects motion. In this manner, the tag conserves power since the tag is typically only in motion ten percent of the day. If the tag is removed from the asset, the optical sensor confirms the removal and an alert is activated by the system. | 04-23-2009 |
| 20090140861 | Wireless Tracking System And Method With Extreme Temperature Resistant Tag - A wireless tracking system and method for real-time location tracking of a extreme-temperature sterilizable object is disclosed herein. The system and method utilize a tag attached to the extreme-temperature sterilizable object which includes a housing, a processor, a temperature sensor and a transceiver. If an internal temperature of the tag is detected by the temperature sensor, the tag enters a sleep mode. The temperature sensor periodically activates to determine if the internal temperature of the tag is within an acceptable operating range. | 06-04-2009 |
| 20090219210 | Wireless Tracking System And Method With Multipath Error Mitigation | 09-03-2009 |
| 20090231108 | Wireless Tracking System And Method With Extreme Temperature Resistant Tag - A wireless tracking system and method for real-time location tracking of an extreme-temperature sterilizable object is disclosed herein. The system and method utilize a tag attached to the extreme-temperature sterilizable object which includes a housing, a processor, a temperature sensor and a transceiver. If an internal temperature of the tag is detected by the temperature sensor, the tag enters a sleep mode. The temperature sensor periodically activates to determine if the internal temperature of the tag is within an acceptable operating range. | 09-17-2009 |
| 20090309732 | Wireless Tracking System And Method With Tag Removal Detection - A wireless tracking system and method with a tag removal detection feature is disclosed herein. The system and method utilize a tag attached to an asset which includes a processor, a motion sensor (such as an accelerometer), a transceiver, a tag removal sensor and a power source having a limited supply of power. The tag removal sensor is a closed circuit device which is activated only when the motion sensor detects motion. In this manner, the tag conserves power since the tag is typically only in motion ten percent of the day. If the tag is removed from the asset, the closed circuit is opened, which confirms the removal of the tag from the asset, and an alert is activated by the system. | 12-17-2009 |
