    摘要: A location system and method for determining the location of a tagged item in a facility. In one embodiment, the location system includes a plurality of room transmitters designed to be located throughout the facility. Each room transmitter has a unique signature. The system also includes at least one item or location tag affixed or otherwise associated with an item. Each tag is operable to send a signal having information related to the signature of a room transmitter within the reception range of the tag and information related to the identity of the tag. Signals from the tags are received by one or more locating receivers. Each locating receiver is operable to determine the identity of an item tag and the likely location of the item tag within the facility based upon the signal from that tag. The invention also provides a method of locating an item in a facility. In one embodiment, the method includes positioning room transmitters in multiple areas within a facility; configuring each room transmitter to generate a unique signature; fitting items with a tag; configuring each tag to generate a signal having a location portion and a signature portion; positioning a locating receiver within the facility; and determining the likely location and identity of that tag based on the tag's signal.

    摘要: A system and method of servicing a mobile magnet by wireless monitoring is provided. The mobile magnet has a sensor configured to sense a characteristic of the mobile magnet and a computer coupled to the sensor configured to receive sensor data representative of the sensed characteristic. The method includes receiving the sensor data at a remote monitoring station via a wireless communication link with the computer; determining whether the mobile magnet needs service based on the sensor data; and dispatching a service technician to the mobile magnet when the mobile magnet needs service.

    摘要: A method for data exchange with a mobile asset wherein the communication link quality at the location of the mobile asset is measured at the time of the data transfer. The packet size for the data transfer is selected in response to the communication link quality. The current communication link quality measurement may be used alone or in combination with historical communication link quality data for selecting the data packet size. Communication link quality may be determined repeatedly and the packet size reset accordingly in response to changes in the link quality. A difference between the current communication link quality and historical link quality data may trigger appropriate corrective action, such as identifying the source of intentional or unintentional jamming.
