    Abstract: A pressure transducer assembly (10) is disclosed for directly monitoring pressure in a fluid which flows through the assembly. The assembly includes a housing (16) defining a chamber (18) therewithin and having an inlet port (26) and an outlet port (28) in fluid-flow communication with the chamber. An electrically insulated body element (24) is sealed within the chamber dividing the chamber into a first chamber (20) and a second chamber (22). The first chamber is in fluid-flow communication with the inlet and outlet ports. The second chamber is separated from the first chamber by a fluid-tight seal such that any fluid present in the first chamber cannot enter the second chamber. A pressure transducer sensor (32) is secured in the insulated body and exposed to the first chamber such that the sensor can determine the pressure in a fluid in the first chamber and convert the pressure into electric impulses. The sensor is separated from the fluid in the first chamber by an insulating medium (34) across which fluid pressure can be determined. Connected to the sensor are electrical conductors (36) which extend through the insulated body and into the second chamber. The second chamber provides an engagement site for an electrical connector (38) which can inte- connect with the electrical conductors and provide an electrical path through which the electric impulses generated by the sensor can be transferred to a monitor (56).

    Abstract: Die Erfindung bezieht sich auf eine Einrichtung haupt sächlich zur Wahrnehmung und Vermeidung von Dyspho nie-Symptomen in Kindesalter.
    Das gesteckte Ziel wird im Sinne der Erfindung durch eine Einrichtung erreicht, die dadurch charakterisiert werden kann, daß ein zweistufiger IC-Verstärker (3), der mit Meßfühl punkten (2) verbunden ist und ein Potentiometer, das sich zwischen den einzelnen Stufen befindet, sowie einen sym metrischen Eingang besitzt, einerseits an einen LED- Indikator (4), der zweckmäßigerweise eine LED-Reihe (6) aus 16 Gliedern und einen IC Typ UAA 170, der in funkioneller Beziehung dazu steht, enthält, und andererseits an ein akustisches Warngerät (5), das einen mit einem Tonertei lungsgerät (7) zusammengebauten Gatterschaltkreis aus Kondensatoren und Widerständen sowie eine Zener-Diode, die mit letzterem verbunden ist, enthält, geschaltet ist.
    Die Speiseeinheit (8) der Einrichtung enthält acht Baby- Zellen von je 1,5 V. Ihre maximale Stromaufnahme beträgt ca. 20 mA, so daß eine Garnitur Zellen mindestens 50 Betriebsstunden ermöglicht. Unter Berücksichtigung von Gesichtspunkten der Wirtschatlichkeit können auch die sog. Baby-Batterien verwendet werden. Ein Betrieb vom Netz aus ist nicht zweckmäßig, weil die Filterung der von dort kommenden Störungen und die Sicherung des Berührungs schutzes komplizierte und teure Schaltkreislösungen erfor derlich machen würden. Nach dem Einschalten des Haupt schalters kann die die Zellenspannung an einem Indikator- Instrument, das direkt für diesen Zweck eingebaut wurd, kontrolliert werden.

    Abstract: Microwave thermography apparatus comprising a signal-receiving aerial (2) which is sensitive to microwave radiation emanating from a body having a mean body temperature. A reference load (1) capable of being maintained at a chosen temperature (To) and of emitting a thermal noise signal at microwave frequency corresponding to temperature To, is connected to a receiver (3) the input impedance of which is matched to the impedance of reference load (1) by way of a 3-port non-reciprocal circulator (5). Aerial (2) is connected via a single-throw on/off microwave switch (6) to the input of receiver (3) through the other port of circulator (5). The connections to circulator (5), taken in circulation order, are reference load (1 aerial (2), receiver (3). Aerial (2) is preferentially designed to incorporate a tubular metallic waveguide (10) of circular cross-section dimensioned to support TE 11 wave mode and the lower order mode, the signal output from the aerial (2) being taken by a coaxial line and the aerial (2) incorporating a broad band waveguide coaxial line mode transformer (11, 12) which is arranged to select only the TEll mode for delivery to the coaxial line. The waveguide (10) is filled with a low-loss dielectric material (13) in order to provide the aerial (2) with an impedance close to the mean body tissue impedance (about 80 ohms).

    Abstract: A device for the ocular determination of any discrepancy in the luminescence capacity of the surface of a tooth (4) for the purpose of assessing the extent of any part (4a) of the surface of the tooth exhibiting caries and/or a coating and/or a defect. The surface of the tooth (4) is illuminated by means of a light (3) with a predetermined wavelength and/or wave range, for example a laser light. The luminescence capacity of the surface of the tooth at another wavelength and/or within another wave range shall be assessed, when any caried or similar part (4a) will show a discrepancy in relation to the normal luminescence capacity of the tooth (4) and will be perceived as a darker area. If the surface of the tooth (4) is illuminated by means of a light which is visible to the eye, then the observer (5) shall use an absorption filter (6) capable of absorbing light at the emitted wavelength or wave range reflected from the surface of the tooth. The invention may also be used in the course of treatment in order to determine when the caried part has been removed from the enamel surface and/or dentine surface produced by the treatment.

    Abstract: A gamma ray scintillation camera generating (X, Y) spatial coordinate and Z energy signals relative to detected radiation events. The camera signals are converted to their digital equivalents subsequent to which the apparent coordinate locations of detected events as determined by the camera are corrected to their true spatial coordinates based upon correction information stored in the system. In addition to spatial coordinate correction, the system provides for calibration of the camera Z signal response as a function of camera face location.

    Abstract: A sterilizable endoscope of small diameter has a central coherent fibre bundle for carrying an image to a viewing means, and the fibre bundle is surrounded by light fibres. The proximate end of the endoscope is provided with a coupling means (14) for aligning the coherent optical bundle with the optical system of the viewing means and for providing an interface with light transmitting means to transmit light from a light source along the light fibres to a body cavity to be inspected. The coupling means (14) may have a diameter no bigger than the diameter of the covering of the endoscope. When the endoscope is used inside a larger endoscope or a trochar, the latter can be removed while the former remains in place. This is accomplished by removing the viewing means and sliding the larger endoscope or trochar over the other endoscope and then replacing the viewing means for further viewing within the body cavity. The device can be used for detection of cancer cells and treatment thereof by phototherapy. A dye is attached to the tissue being examined and subsequently exposed to an exciting laser light frequency. Cancer cells will emit fluorescent light which is detected and displayed on the video monitor and the same light frequency is then transmitted through the light fibres to the cell for phototherapy treatment.

    Abstract: A portable, self-contained, microprocessor controlled apparatus for monitoring, storing and transmitting detected physiological information, including means for sequentially receiving analog signals corresponding to heart activity for as many as twelve different cardiac sensors. Means are provided for receiving analog electrical signals corresponding to blood pressure from at least one sensor. Means are providing for converting the received analog signals to a series of digital pulses at a predetermined sampling rate and for receiving and storing the digital pulses in predetermined memory locations. Means are provided for recalling the stored digital pulses from the memory means and for receiving the recalled digital pulses and for transmitting them to a remote location over a communications system. In the preferred embodiment, means are provided for receiving analog signals corresponding to cardiac conductivity, brainwave activity, blood pressure, blood flow and other ultrasonic cardiovascular and intracranial data. The latter signals are also converted to digital form for storage and later recall and transmission to a remote location.
