    • A vibrometer which detects the variation of the speckle interference pattern of reflected waves as a means of determining the amplitude and frequency of vibrations of structures, including small anatomical structures. A wave source such as a laser delivers wave radiation to the object whose vibration is to be measured. The diffuse reflectance from the textural surface of the object reflects the incident wave radiation as a speckle interference pattern which is detected by a detector, such as a photodetector. The wave radiation source may be a continuous-wave laser, and the photodetector detector may be a phototransistor connected to a wide-bandwidth amplifier. As the object vibrates, the speckle interference pattern moves. The variation in the speckle interference pattern across the detector carries amplitude and frequency information regarding the vibrating object.

    • Apparatus and method for separating individual human reproductive material from a fertilization dish and storing the material in a cryotank for future fertilization and implantation. The apparatus includes an elongate cryostraw having a first open end and second heat-sealable open end, a channel extending between said ends, and an internal, calibrated volume VC. A displacement bulb is connected to the first end of the cryostraw for admitting and emitting the material into said cryostraw. The bulb has a total volume VB1, an internal cavity with a compressible end volume VB2, a first seal with the first end of said cryostraw; and, means for limiting the intake volume displacement produced in said cryostraw to an amount less than VC no matter how far the bulb is squeezed. The bulb produces less than a unit volume of displacement in the cryostraw when the bulb is squeezed and its volume VB1 is reduced by a unit volume.

    • A method, apparatus, and set of compositions are disclosed for calibrating a bio-photonic scanner. The scanner detects selected molecular structures of tissues, nondestructively, in vivo. The apparatus may include a computer, including processor and memory connecting to the scanner, including an illuminator to direct light nondestructively onto tissue in vivo, a detector to detect an intensity of a radiant response of the tissue to the light, and a probe to direct light onto the subject and receive a radiant response back into the detector. The apparatus is calibrated using a synthetic material to mimic the radiant response of live tissue, correcting for background fluorescence and elastic scattering. Dopants in a matrix of synthetic material mimic selected molecular structures of tissue. Matrix materials include a dilatant compound, and dopants include biological materials as well as K-type polarizing film powdered and mixed.

    • An apparatus and method for thermally destroying tumors in which heat is generated by electrical resistance heating conducted to the target tissue. Computerized scanning is used to optimize the geometry of a thermal probe. The probe has a metal tip heated by a remote laser. The metal tip is mounted on the end of a wave guide fiber for transmitting the laser radiation to the metal tip. The tip is coated with a thin layer of biocompatible ceramic to avoid coagulated tissue sticking to the tip. The tip has one or more thin, thermally-conductive elements which deploy in stages to coagulate the tumor. The conductive elements may be thin wires or blades. On one embodiment, the conductive elements are composed of a shape memory material that is folded against the tip at lower temperatures and deploys at selected higher temperatures. In another embodiment, the conductive elements are blades that are deployed mechanically. The tip may be provided with a miniature thermocouple to provide temperature feedback information.
