Abstract: An underwater energy storage system includes a tank for storing a compressed gas that is adapted to be stored underwater. The tank includes at least one water opening through which water from surrounding environment can flow into and out of the tank, and at least one gas opening through which the compressed gas is received. The underwater energy storage system further includes at least one duct communicating between the at least one opening for gas flow and a source of compressed gas and a compartment constructed over a roof of the tank, wherein said compartment is adapted for receiving weights at a sinking site of the tank.

Abstract: A system and method for tracking the health of a group of livestock. In an exemplary embodiment of the invention, the vital signs of a small number of sentinel animals is tracked and used to assess the existence and/or progress of a disease in the group. In an exemplary embodiment of the invention, the vital signs are assessed using a vitality sensor, for example, an accelerometer which provides signals indicating the type and/or other properties of movements made by the sentinel animals.

Abstract: A device (100) for heating a flow of liquid from an initial temperature to a desired temperature for intravenous delivery includes an elongated conduit (120) formed from metallic material having an inlet (102) for receiving the flow of liquid at the initial temperature and an outlet (104) for delivering the flow of liquid at the desired temperature. A temperature sensing arrangement (160. 162, 224) is deployed to generate an output indicating the temperature of the liquid at a number of locations along the conduit (120). A controller (140) generates electrical current flowing within at least one length of the wall of the conduit, thereby generating heat within the wall so as to heat the flow of liquid to reach the desired temperature at the outlet.

Abstract: A card game played with a deck of playing cards in a native language that are organized in thematic suits. Each player aims at having as many full suits as possible. Each player in turn asks other players for cards out of suits held by the player. The thematic suits comprise playing cards with expressions in at least one foreign language. Playing the game promotes the knowledge of the players of the foreign languages.
