Abstract: A system for supplying power to an electric submersible pump is provided. The system includes a variable frequency drive connected to a motor. The motor is mechanically connected to the electric submersible pump. A generator and a battery are connected to the variable frequency drive. The battery is appropriately sized so that it can power the variable frequency drive during startup operations of the electric submersible pump and during generator maintenance periods. The system includes a means for detecting when power from the generator is insufficient to meet the load demand of the electric submersible pump. When that occurs, the battery sends power to the variable frequency drive to meet the load demand of the electric submersible pump. The system also includes a means for charging the battery using the generator when the battery has dropped below a threshold level.

Abstract: A pulmonary delivery device (300) with a first chamber (206) adapted to thermally vaporise a quantity of a first fluid to form a relatively warm first vapour and a second chamber (208) adapted to atomize a quantity of a second fluid without heating of the second fluid to form a mist of a relatively cold, second vapour, the device further comprising an outlet via which, in use, a user can inhale a mixture of the first and second vapours. The second chamber is in the form of a passive atomiser wherein the second chamber is selectively or continuously in fluid communication with air, the second chamber including at least one flavouring or aroma wherein the flavour is inhaled by drawing air through the chamber.

Abstract: An NG feeding tube tip (50) is disclosed, which has a main body portion that fits to the end of an NG or OG feeding tube (20). The main body has a hollow interior that is in fluid communication with the bore of the NG or OG tube (20); and an aperture (56) in a sidewall through which feed can be given to a patient, and through which a sample of stomach content can be aspirated. The tip (50) is characterised by the outer wall of the main body comprising a recess or groove (60, 62, 80), which intersects the aperture (56), and which extends at least partially around the exterior surface of the main body. The recess or groove (60, 62, 80) prevents or inhibits an aperture-occluding seal between the stomach wall (30) and the NG or OG tube tip being formed, especially when a vacuum is applied to the NG or OG tube (20) during an aspiration procedure.

Abstract: A method and apparatus for monitoring intravenous drips by the transmission and detection of a signal, for example a red light, through a fluid flow passage whereby detection of a signal of a given intensity activates an audible or visual indicator. A bracket is attached around a fluid flow passage of the intravenous drip and a signal is transmitted across the passage via optical fibers. The intensity of the signal is detected by a sensor contained within a remote housing.
