摘要： A system and method for providing a substantially constant volume exhaust or ventilation air terminal system is shown for controlling exhaust and/or return airflow rates in a system having a central fan or ventilator. The system and method permits zone-by-zone or area-by-area airflow regulation or control in non-demand areas in response to a demand or call for ventilation in demand areas. In one embodiment, the system employs at least one constant airflow controller or regulator situated in a damper. In one embodiment, a terminal houses a plurality of sub-ducts each having an airflow regulator. At least one of the sub-ducts has a damper. When the damper is open, a maximum airflow through the terminal is a sum of maximum airflow permitted by the regulators.

摘要： A medical endosurgical device is provided having both ultrasonic imaging and biopsy capabilities for easy grasping and manipulation by a surgeon. The medical endosurgical apparatus includes an ultrasonic imaging probe having an insertion portion with an ultrasonic device near the insertion tip and a probe handle for manipulating the ultrasonic imaging probe to position the ultrasonic device in the patient's body. The medical endosurgical device also includes a biopsy actuator that is mounted on the handle of the ultrasonic imaging probe so that a biopsy needle assembly exiting from the biopsy actuator is oriented to the field of view of the ultrasonic device on the probe. The medical endosurgical apparatus may also include a rigid sheath disposed over the insertion portion of the ultrasonic imaging probe that is engaged with and oriented to the ultrasonic imaging probe such that a biopsy needle assembly passing through a lumen in the rigid sheath would be oriented to the field of view of the ultrasonic device.

摘要： A sheath for receiving an ultrasonic probe and for defining the relative position of the probe with respect to a biopsy gun or a rigid needle is used for precise placement of the biopsy gun or needle tip in a structure. The sheath may comprise a keyhole-shaped slot for placement of a rigid needle through a puncture separate from a surgical port through which the sheath itself and the probe are introduced. A flexible catheter can thus be placed in a structure, using the ultrasonic probe to monitor its placement, followed by removal of the probe sheath and surgical port, leaving the catheter in place.

摘要： Apparatus for sensing particles in a fluid medium comprising an ultrasonic resonant cavity for containing a fluid medium. A first transducer on one side of the cavity continuously propagates thereacross ultrasonic compressional waves whose phase and amplitude are perturbed by the presence of particles in the fluid medium. A second transducer positioned on the opposite side of the cavity from the first transducer substantially parallel to and in registry therewith receives the ultrasonic waves and converts them to rf electric waves of the same frequency, the rf electric waves having their phases and amplitudes modulated in response to any perturbations in the ultrasonic waves. The rf waves are amplified and fedback to the first transducer thereby to establish an oscillatory circuit. An attenuator in the oscillatory circuit causes its operation to be marginally oscillatory whereby small changes in the amplitude of the rf waves caused by any perturbations in the ultrasonic waves produce relatively large changes in the amplitude thereof. A detector responsive to perturbations in the rf wave demodulates the amplified rf wave to produce signals indicative of the presence of particles in the fluid medium. Thus, enhanced sensitivity to small changes in the ultrasonic properties of the fluid medium caused by the presence of particles therein is achieved.
