A tracking system and method provide updated location and status information of a vending machine even after the vending machine is moved from its installed location. This allows law enforcement to use the updated location information to locate and recover the vending machine and the assets contained therein during a theft or in other security breach situations. A method also provides for automatically assigning the vending machine to an installation location using the location and status information from the vending machine.

The tolerance of Short-Open-Load (SOL) and Short-Open-Load-Reflect (SOLR) VNA calibration for variability in probe position is improved by using load and short calibration structures having impedance elements with a length at least two times the probe contact pitch and a width at least two times the sum of the combined pitches of the probe contacts.
摘要:
A system and method is disclosed for corresponding data associated with primary correction of at least one first measurement of a GPS satellite characteristic to a second measurement of the GPS satellite characteristic taken at a mobile receiver. In a preferred embodiment of the invention, a first processor is coupled to at least one wide-area GPS corrections receiver and at least one local-area GPS corrections receiver. The wide-area and local-area receivers operate to determine the first measurement and secondary data associated with correction of the determined first measurement. In operation, an estimate of the location of the mobile receiver is determined by the first processor. The availability to the mobile receiver of the secondary correction data from the wide-area and local-area GPS corrections receivers is determined, preferably based on the location estimate. From the secondary correction data, primary data representing the primary correction is determined by the first processor. The primary data and the second measurement data are preferably colocated by causing the first processor to transmit the primary correction data to the mobile receiver.

In one embodiment, a method is provided for selectively providing an alert to a user of a tracked asset in an asset recovery system. The method includes activating a tracking device on the tracked asset to generate a report, evaluating the report and a condition based on a home location assigned to the tracking device for generating an alert, creating the alert based on the evaluation of the condition and the report, and sending the alert to the user.

In a membrane probing apparatus, the impedance of the interface between coaxial cables connected to the test instrumentation and the membrane supported co-planar waveguide that conductively connects to the probe's contacts is optimized by eliminating a ground plane in the interface board.

A method of using altitude information to arrive at a more accurate GPS position. A 3D GPS position is used as an initial estimate. The latitude and longitude of the initial estimate are used to retrieve an altitude from a database. This altitude is used to calculate a 2D GPS position. The 2D GPS position is then used to retrieve another altitude from the database, and the calculate-retrieve process is continued until the calculation converges.
