Abstract: A cover retention mechanism for releasably locking a cover to a base such as a gage housing. The cover retention mechanism includes a base lock having a receiver and a receptacle, and a cover lock having a latch attached to an end of a flexible arm. The latch is selectively movable between a retracted position wherein the latch engages the receptacle to prevent rotational movement of the cover with respect to the housing from the closed position toward an open position, and an extended position wherein the latch is removed from the receptacle and the cover is rotatable with respect to the housing from the closed position toward the open position.

Abstract: Econometric information is produced based upon real data that has been electronically acquired in real time. The acquired data is analyzed to select data records having attributes unique to a particular activity of interest. The selected data records are aggregated, adjusted, and used to create a statistical index or metric related to an economic activity. The statistical index or metric, together with information illustrating or interpreting information, is electronically distributed. As an example, a Pulse of Commerce Index related to shipment of goods is produced by electronically processing and storing data relating to financial transactions involved in purchase of goods and services. Data records are selected that involve fuel purchases, which act as a proxy for freight activity. Using the selected data records, both national and regional indices based upon fuel purchases are produced and distributed.

Abstract: An enclosure for a gage including a housing and cover. The cover includes one or more mounting lugs and the housing includes one or more mounting mechanisms. Each mounting mechanism includes an inclined ramp to facilitate removal of the cover from the housing by rotational movement of the cover with respect to the housing.
