A location-based service includes detecting the relative motion of an on-site resource, detecting the absolute position of the on-site resource, and tracking the position of the on-site resource. The position is tracked by deriving a deduced position based on the detected relative motion and adjusting the deduced position as a function of and in response to the detected absolute position. According to one embodiment, the on-site resource can be a shopping cart and the tracking includes recording a travel pattern of the shopping cart as it moves through a site floor plan such that the travel pattern is reproducible. Preferably, the recorded travel pattern includes travel patterns within an aisle in the site floor plan such that the recorded patterns include travel along the length of the aisle and travel having components which are perpendicular to the length of the aisle.

Tiered on-demand location-based tracking service and infrastructure

As disclosed herein, a method for determining when a coin storage bin having a bottom and sides is filled to a predetermined percentage of the volume of the coin storage bin comprises: determining a coin volume for a coin entering the coin storage bin, adding the coin volumes for each coin entering the coin storage bin to provide a running total volume of all coins entering the coin storage bin, comparing the running total volume of all coins entering the coin storage bin with the volume of the coin storage bin, and determining when the running total volume of all coins entering the coin storage bin is greater than or equal to the predetermined percentage of the volume of the coin storage bin. The volume for a coin can be determined from information provided by a coin acceptor, where the information is thickness, diameter, weight, or a combination comprising at least one of these.

Using coin dimensions and coin storage bin volume to estimate when bin is full

A location-based service includes detecting the relative motion of an on-site resource, such as a shopping cart, in addition to detecting the absolute position of the on-site resource, and displaying information on the on-site resource. The displayed information is based upon the detected relative motion and the detected absolute position. The relative motion is tracked and a position on a floor plan is deduced. This deduced position is adjusted, for example, synchronized or reset, as a function of and in response to the detected absolute position.
