Abstract: A method of tracking inventory comprises providing a dispenser. The dispenser includes a body laterally extending between a first end and a second end. The dispenser also includes a stopper slidably coupled to the body to move between the first end and the second end and a biasing member coupled to the stopper to bias the stopper towards the second end. A plurality of identifiers are displayed on the biasing member. The method includes securing a plurality of units within the dispenser between the stopper and the second end, and displaying at least one of the plurality of identifiers to a user of the dispenser, the at least one of the plurality of identifiers corresponding to a total number of units in the dispenser.

Abstract: A method of tracking inventory comprises storing at least one container unit within a dispenser. The dispenser includes a first and second ledge. The dispenser secures at least one container unit within the dispenser using an arm, wherein the arm has a first face. A total container unit distance is determined, wherein the total container unit distance is the distance between the first face and the second ledge. A single container unit distance is identified, wherein the single container unit distance is the change in distance between the first face and the second ledge when a single container unit is removed from the dispenser. A total number of container units in the dispenser is determined, wherein the total number of container units in the dispenser is determined using the total container unit distance by the single container unit distance. The total number of container units in the dispenser is displayed.

Abstract: A semiconductor tray carrier has a base part and first and second side parts. The first and second side parts are movable between a stowed position and a deployed position in which the side parts extend from the base part to form side walls. Multiple tray carriers can be stacked one upon the other when the side walls are in either the stowed or deployed positions. When stacked in the stowed position, the tray carriers require very little storage space. Windows are provided for attaching details on the contents of the tray carriers.
