    • The present invention includes an adjustable head set held in place on the back of a patient's head when the patient leans back against a chair head rest. The head set includes self-preparing disposable monitors that provide good contact with the patient's head without prior skin preparation. The monitors include a conductive tube containing conductive wires, the tips of which form a planar cushion surface for contacting the patient's head through a caratinaceous layer of skin. The monitors are held in adjustable holders that allow the contact force to be adjusted. The adjustable holders are mounted in holder slots of head set springs where the slots also allow adjustment of the placement of the monitors. The springs can include hinges for rotatably adjusting placement of the monitors. The disposable monitors are filled with an electrolyte solution using a disposable applicator including a puncturable film, punctured by a monitor when the electrolyte solution is being applied.
    • 本发明包括当患者靠在椅子头枕上时靠在患者头部的背部时保持在适当位置的可调节头部组件。 头套包括自制一次性显示器,与患者的头部良好接触,无需事先进行皮肤准备。 监视器包括一个导电管,其中包含导电线,其顶端形成一个平面的缓冲表面,用于使患者的头部通过皮质层的接触层接触。 显示器保持在可调节的支架中,允许调节接触力。 可调节的保持器安装在头部固定弹簧的保持器槽中,其中槽还允许调节显示器的位置。 弹簧可以包括用于可旋转地调节显示器的放置的铰链。 一次性显示器使用包括可刺穿膜的一次性敷料填充电解质溶液,当施加电解质溶液时由监护仪刺穿。

    • A method and apparatus is shown and described for remotely closing a well(s) without the possibility of accidental closure. The method and apparatus will have a significant application to underwater wells. A point of activation of a gas generator is remotely located away from the well to avoid debris that may fall at or near the well. A diver or technician brings the means for activating the gas generator to the activation point of the gas generator. Upon activation, pressure generated by the gas generator is transferred by appropriate conduit means to well closure equipment which may include a crimping device, a "U" type blowout preventer, blind rams or any combination thereof. The faces of rams used to pinch concentrical strings of pipe may be shaped to seal the outer strings of pipe as well as inner strings.
    • 示出和描述了用于远程关闭井的方法和装置,而没有意外关闭的可能性。 该方法和装置将对水下井具有重要的应用。 气体发生器的激活点远离井,以避免可能落在井或其附近的碎屑。 潜水员或技术人员将气体发生器的启动装置带入气体发生器的活化点。 在激活时,由气体发生器产生的压力通过适当的导管装置传送到井封装置,该装置可以包括压接装置,“U”型防喷器,盲杆或其组合。 用于挤压管道的同心圆柱的公羊的面可以被成形为密封管的外部串以及内部绳。

    • The present invention provides a method of obtaining an organism which has been characterized as having cells containing exogenous genetic material which includes any sequence of DNA that can be distinguished as exogenous by known molecular biological analysis by insertion of genetic material into an animal's genetic makeup. The insertion of the genetic material is done by inserting DNA that has been complexed with molecules that allow the DNA to be inserted into the chromosomes when injected into the cytoplasm, perivitelline space, or placed in surrounding culture media to be taken up and incorporated into the genome. When the DNA is complexed into the polyelectrolyte molecules by electrostatic attraction, the electric charge of DNA of the complex is partially to substantially neutralized. The present method does not require the genetic material to be introduced into the embryo at a particular stage in development.

    • An optical scanning device for mechanically scanning images at a high scanate over a wide field of view and under low light conditions. The device comprises a first rotating reflecting means such as mirrors for intersecting an input beam of light in a first path and for redirecting the beam of light into a second path. A second rotating reflecting means intersects the second path and reflects the beam of light into a third path, onto a detecting device for detecting the presence of predetermined images in the beam of light. In order to reflect the light beams over an elliptical path the mirrors are mounted on rotating shafts at a slight angle from the perpendicular to the axis of the rotating shaft. The mirrors are rotated at varying speed relationships to each other and varying phase relationships to each other in order to produce a variety of scan patterns.
