Abstract: A food donation tracking system is provided for tracking food donations along a food donation route that includes a food recipient location and a plurality of food rescue locations. The system includes a display device at each of the food rescue locations, each display device being operable to generate a dynamic unique code specific to the food rescue location where the display device is located. A driver scans the dynamic unique code with a handheld unit. Tracking information is recorded and transmitted from the handheld unit to a central server. The tracking information includes location information identifying the food rescue location of the food donation pickup based on the dynamic unique code scanned at the food rescue location and time information corresponding to when the unique code was scanned at the food rescue location.

Abstract: A retainer for retaining an electronic module, such as a printed circuit board, in the slot of a casing. Oppositely oriented wedge-shaped elements are slidingly received on a rail in a manner which prevents rotation of the wedge-shaped elements about the rail. A pivotable lever having a cam surface is provided such that rotation of the lever actuates the retainer by compressing the wedge-shaped elements. In one embodiment, the lever is provided with a projection which engages the casing to extract the module when the lever is pivoted to release the retainer.
