Abstract: Embodiments provide systems, methods, and computer program products for tracking objects within a domain and their possible changes and genealogy over time. An object identifier and an interval identifier are associated with an object that enters the domain with an unknown set of attributes and genealogy. The object identifier is analyzed to determine whether it is a pre-existing object identifier. A comparison of the interval identifier is performed to determine whether the object is a copy of a prior object. The object identifier is replaced with a new object identifier and the interval identifier reset when the object is new or a copy. Based on the object identifier and the interval identifier, which represents the possibility of change during each interval, information about the tracked object may be derived and analyzed to enhance performance.

Abstract: A disposable spoon having a hollow main housing with a spoon that is releasably attached to the main housing. When the user places a food packet inside the main housing, the spoon pierces the food packet. A movable extruder actuator is operatively attached to an extruder blade. When the user slides the movable extruder actuator, the extruder blade compresses the food packet causing the contents of the food packet to extruded from the food packet and onto the spoon.

Abstract: A dispenser for sequentially dispensing one sheet at a time from a stack of sheets. A housing encloses a drive and a lift roller, and each roller has a longitudinal axis arranged in parallel aligned relationship respective to one another and spaced from the one another an amount to bring the outer peripheral surfaces thereof into rolling contact with one another. A holding post is aligned in parallel relationship with respect to the rollers and is spaced therefrom for enabling a stack of sheets to be held against the holding post and lift roller, with one outermost sheet having a marginal edge portion thereof urged against the lift roller and the opposed marginal edge portion thereof is urged against the holding post. The outer peripheral surface of the drive roller is made of high friction material while the lift roller has a relatively small segment of its outer peripheral surface made of high friction material and the remainder of the peripheral surface made of low friction material.
