Abstract: Releasable magnetic pole strap systems are disclosed. Embodiments are directed to a releasable magnetic pole strap system including a pole which includes: a proximal end having a distal surface; and a pole attachment device connected to the distal surface of the proximal end of the pole. The system also includes a strap including a strap attachment device which is configured to be releasably attached to the pole attachment device. The distal surface of the proximal end of the pole is at least partially covered by the pole attachment device. Each of the pole attachment device and the strap attachment device includes either a magnet or a non-magnetic ferric material. At least one of the pole attachment device or the strap attachment device includes a magnet.

Abstract: An improved buoyancy compensation device having a lesser change in buoyancy with depth than conventional buoyancy compensation devices which use ambient pressure bladders is disclosed. The improved device comprises one or more elastic members that, throughout the working range of diving pressures and volumes, is always elastic and, when pressurized, maintains an internal air pressure that is always greater than the ambient pressure at any dive depth. The invention also relates to a method of providing a buoyancy compensation device with an elastic member having a lift versus depth characteristic that approaches the lift versus depth characteristic of a constant or fixed volume buoyancy compensation device.

Abstract: This device uses electrical impedance and signal processing to measure the small change in volume (“Pulse Volume”) of a limb-segment that occurs with each heartbeat. “Pulsatile Flow” is defined as the pulse volume multiplied by the heart rate and is an index of tissue perfusion. This information can be combined with measured blood oxygen saturation to determine how much oxygen is reaching the tissues. The combination of knowing oxygen saturation and tissue perfusion is far more useful than knowing just one or the other of these parameters.

Abstract: A device for non-invasive measurement of blood pressure includes a blood pressure cuff, a plethysmographic electrode for acquiring an impedance plethysmogram distal to the cuff and a processing device to inflate and deflate the cuff, generate the impedance plethysmogram and to determine the systolic and diastolic blood pressures. It is determined when the cuff is completely occluding the extremity, e.g., by detecting pulses at a second, partially occluded cuff or by a photoplethysmogram attached to the big toe. The device can be used to measure systolic or diastolic blood pressure or both. It can also be used to take ankle-brachial measurements. An autocorrelation technique can be used to correct noise.

Abstract: A multi-function fluid communication control system for effecting selective automated control of fluid communication between fluid sources and instruments is disclosed. The system comprises a disposable stopcock manifold having a plurality of stopcocks adapted to be releasably connected to an actuator system which automatically operates the stopcocks. The stopcocks may also be manually operated to override the automatic operation of the stopcocks. The actuator system for the stopcock manifold is controllable by a microprocessor.
