Abstract: A system and method for sanitizing or cleaning an item, such as a grocery store shopping cart or a child stroller, for re-use utilizes a passageway having an entrance and an exit and a sanitizing or cleaning station between the entrance and exit. The item is conveyed through the passageway into the station, and pulsating beams of ultraviolet (UV) light are directed toward the item to sanitize the surfaces of the item which are struck by the pulsating beams of light. The system can be supplemented with an arrangement for directing water toward the item for rinsing purposes and for subsequently directing air toward the item for drying purposes. Moreover, the rinse water can be collected and sanitized after it has been directed toward the item during a rinsing operation for subsequent re-use.

Abstract: A heat sink having a very high heat transfer capability may be made from a plurality of unit elements. Each unit element includes a series of inlet tubes having a range of diameters and a series of outlet tubes also having a range of diameters. At least one inlet tube having a minimum inlet tube diameter may be in flow communication with at least one outlet tube having a minimum outlet tube diameter.

Abstract: The present invention is a method, system and investment product for allocating or structuring investment assets (such as marketable securities, bonds, mortgages, or other property interests, options or derivatives). The system, method or product enables selecting or grouping a number of individual financial instruments together into a portfolio (e.g., a fund or trust) and assigning weight coefficients to the selected financial instruments based upon a predetermined scale. After assigning the weight coefficients, the system or method purchases the selected instruments based on the allocated total purchase for each instrument (i.e., the total price of each instrument reflects is the price per unit×number of units, which correspond the predetermined weight coefficient). Then, the purchased individual financial instruments are allowed to fluctuate and perform for a predetermined time period (i.e., a number of years and months) without any further significant adjustments to the initial portfolio.
