Abstract: A display system for ice rinks comprises a panel having at least one enclosure containing a plurality of LEDs for displaying any indicia or images etc. The panel is adapted to be placed under the ice when in use. The panel is provided with a cooling apparatus for circulating a coolant through the at least one enclosure to remove heat generated by the LEDs. In one aspect, the panel includes at least one channel, within which a plurality of light emitting diodes, LEDs, are provided. The LEDs are controlled to display any indicia or images from under the ice when the panel is in use. The panel includes a manifold system for distributing a coolant through the channels so as to dissipate any heat generated by the LED, thereby, avoiding affecting the temperature of the ice.

Abstract: An assay device for determining the presence of specific analytes in a liquid sample comprises a container for collecting the sample liquid and a removable cap for sealing the container. The cap includes one or more test strips, such as chromatography strips, supported thereon for visually displaying the results of the assay. A chamber in the cap, collects, through an inlet, a volume of liquid from the container when it is inverted by depressing and subsequently releasing a piston located in the chamber. The liquid collected in the chamber is transferred to the chromatography strips by a wicking system. The piston frictionally engages a seal pad made of resilient material. The seal pad closes the inlet and forms a hermetic seal between the liquid contained within the container and the outside thereby preventing such liquid from becoming contaminated and any leakage of the contained liquid.

Abstract: A lid for a liquid sample container is provided which includes an opening for transferring the sample into a further container for conducting the necessary tests and a flexible portion, which allows the sample to be expelled through the opening. The opening is normally closed by a detachable closure which can also be used to re-seal the opening after the desired quantity of the sample has been withdrawn. An apparatus is also provided for obtaining dual liquid samples, which comprises two sample containers, wherein one container is retained within a recess in the other to result in a unitary structure. Further a method of obtaining liquid samples is provided which utilizes containers of the present invention.

Abstract: An assay device for determining the presence of specific analytes in a liquid sample comprises a container for collecting the sample liquid and a removable cap for sealing the container. The cap includes one or more test strips, such as chromatography strips, supported thereon for visually displaying the results of the assay. A reservoir attached to the underside of the cap, collects, through a passageway, a predetermined volume of liquid from the container when it is inverted thereby submerging the reservoir in the sample liquid. The liquid collected in the reservoir is transferred to the chromatography strips by a wicking system. A valve member located in the reservoir automatically swells upon absorbing a portion of the liquid in the reservoir. Such swelling causes the valve member to close the passageway to form a hermetic seal between the liquid contained within the container and the outside thereby preventing such liquid from becoming contaminated and any leakage of the contained liquid.
