A children's seating arrangement for use in vehicles comprises a seat portion pivotably mounted between the upper free ends of a U-shaped bow of rigid material, the lower horizontal end of the bow being releasably mounted in a locking-type floor-mounted fixture and the length of the side arms of the bow being longitudinally adjustable by means of a threaded arrangement on each such arm. The height of the seat can therefore be suitably adjusted, as can the angular position of the seat, and the entire assembly easily removed and replaced by operating the detachable locking means.

A sensor placement and retention mechanism for use with fetal sensor sites beyond the user's reach are disclosed. The preferred embodiment of this invention is a fetal pulse oximetry sensor having an active face through which a light source and a light detector operate. The sensor includes a handle that facilitates placement of the active face at a sensor site in a preferred region beyond the transcervical region and beyond the reach of the user. A pair of electrodes--one disposed against the fetus' skin and one exposed to the amniotic fluid--are used to confirm that the sensor is firmly in place on the fetus. In an optional sensor retention feature, a self-inflating bladder presses the active face of the sensor against the fetus' skin to optically couple the sensor with the tissue at the sensor site.

BE RETAINED IN THE POSITION TAKEN AFTER AN EVACUATION STROKE. A CLOSING VALVE COOPERATES WITH THE EVACUATION CHAMBER, AND THE MOVABLE VALVE MEANS HAS AN ATTACHMENT FOR THE LINE WHICH CAN BE OPENED BY PULLING SAID LINE. A WATER SAMPLING DEVICE, INCLUDING A VESSEL CAPABLE OF BEING CLOSED AND OPENED BY MEANS OF A REMOTE CONTROLLED VALVE AND ADAPTED TO BE LOWERED INTO LAKES, RIVERS ETC. FOR THE PURPOSE OF COLLECTING SAMPLES OF WATER. THE DEVICE INCLUDES A VESSEL CAPABLE OF BEING OPENED AND CLOSED BY A REMOTE CONTROLLED MEANS, A THERMOMETER FOR MEASUREING THE TEMPERATURE OF THE WATER, AND A LINE FOR LOWERING THE VESSEL DOWN TO THE DESIRED DEPTH. IT HAS A SINGLE ACTUATING PUMP, THE PISTON OF WHICH CAN
