Abstract: For analyzing a sample containing particles of at least two categories, such as a sample containing blood cells, a particle counter subject to a detection limit is coupled with an analyzer capable of discerning particle number ratios, such as a visual analyzer, and a processor. A first category of particles can be present beyond detection range limits while a second category of particles is present within respective detection range limits. The concentration of the second category of particles is determined by the particle counter. A ratio of counts of the first category to the second category is determined on the analyzer. The concentration of particles in the first category is calculated on the processor based on the ratio and the count or concentration of particles in the second category.

Abstract: A frame assembly can be configured to couple one or more doors to a refrigeration case having an opening. The frame assembly can be mounted outside the opening of the refrigeration case, which can reduce the amount of energy needed for heating the frame assembly and doors to prevent condensation. Mounting the frame assembly outside the opening can also improve the uniformity of light used to illuminate goods displayed in the refrigeration case. Mounting the frame assembly outside the opening can also allow for the use of larger doors. In some embodiments, and adapter can be used to mount the frame assembly outside the opening. In some embodiments, refrigeration units having a frame assembly mounted in the opening can be retrofitted to include a frame assembly that is mounted outside the opening.

Abstract: This disclosure relates to covers for use with refrigeration units. The covers may include rails that extend across a top opening of the refrigeration unit. One or more lids may be supported by support surfaces on the rails. The lids may be movable (e.g., slidable) between closed and open positions. The lids may include lid plates and feet configured to raise lid plates off of the support surfaces, thereby forming gaps between the lid plates and the support surfaces. The lids may include filling elements to fill at least a portion of the gaps between the lid plates and the support surfaces. In some embodiments, the feet may have a generally Z-shaped configuration. In some embodiments, the cover may include multiple frame elements having transparent spacers at the ends of the frame elements, and the cover may include end pieces at the ends of the cover.

Abstract: A method of transporting commodities in a supply chain management system including a supply chain. The method includes providing a database and a network in communication with the database, which is accessible by at least one member of the supply chain via the network. The method also includes providing a container and supporting one or more commodities using the container, assigning at least one sensor to the commodities, sensing a condition of the commodities and generating a signal indicative of the commodity condition, identifying information related to the commodities, acquiring data related to identifying the commodity information, distributing the signal and the acquired data over the network, storing the signal and the acquired data in the database, monitoring the commodities via the network, and managing at least one of storage and transport of the commodities through the supply chain based on the signal and the acquired data.

Abstract: A refrigerated merchandiser for maintaining food product at a desired temperature. The refrigerated merchandiser includes a case having a product display area adapted to support and display the food product to be visible from the front of the case and a refrigeration system operable to supply refrigerated air to the product display area and adapted to maintain the food product at the desired temperature. The case further includes at least one graphic display panel coupled to the case and a controller in electrical communication with the graphic display panel. The controller delivers a signal to the graphic display panel which displays video advertising based on the signal received from the controller.

Abstract: A refrigerated display case for maintaining food product at a desired temperature includes a product display area adapted to support and to display the food product such that the food product is accessible from the front of the case through an opening. An interior top wall is positioned above the product display area and includes an outlet adjacent the opening. An air passageway internal to the case and in fluid communication with the outlet permits refrigerated air from a refrigeration system to be supplied to the product display area through the outlet. The air discharged from the outlet defines an air curtain adapted to maintain the food product at the desired temperature. A light source is disposed adjacent the interior top wall and inside the air curtain and is adapted to illuminate the food product within the product display area.

Abstract: A refrigerated merchandiser that includes a case defining a product display area. The case includes a base supported by a support surface that includes a primary inlet and a secondary inlet disposed outside of the primary inlet that receives air from adjacent the support surface. A canopy disposed substantially above the product display area includes a primary outlet and a secondary outlet. A primary air passageway fluidly connects the primary inlet with the primary outlet and defines a primary air curtain that flows across an open face portion of the case. A secondary air passageway fluidly connects the secondary inlet with the secondary outlet and defines a secondary air curtain that flows across the open face portion outside of the primary air curtain. An evaporator is located in the primary air passageway to refrigerate the primary air curtain.

Abstract: A variety of refrigerators and merchandisers having glass or plastic substrates that are substantially fog-resistant are provided. For example, refrigerator doors having a substantially transparent substrate including an anti-fog coating on at least a portion thereof are provided. The portion of the substrate may substantially not fog when the portion has an initial surface temperature and is then exposed to a moist air ambient with a dewpoint temperature equal to or greater than the surface temperature for a period of time. The surface temperature may be less than about 0° C. and the period of time may be greater than about 6 seconds.

Abstract: A hydraulic system for a flow cytometry having a reservoir for a sheath solution, at least one syringe connected to the reservoir, the at least one syringe being driven by a motor, a single HGB module connected on an inlet side to a sample inlet which is connected to the flow cell by a single flow path passing through the HGB module, a single flow cell connected to the HGB module and at least one syringe on an inlet side of the flow cell, and to a waste container on an outlet side of said flow cell.

Abstract: A refrigeration merchandiser including at least one surface at least partially defining an environmental space adapted to accommodate a commodity.
