摘要： A system for sensing subterranean acoustic waves emitted from an acoustic source includes a plurality of laser sources, a plurality of subterranean optical sensors, at least one optical detector, and electronics. The laser sources each emit light at a different frequency. The subterranean optical sensors receive the light and alter the light in response to the acoustic waves. The optical detector receives the altered light and outputs an electrical signal. The electronics receives the electrical signal and converts it into seismic data format. Preferably, the light emitted from the optical sources is modulated at a plurality of modulation frequencies. The electronics can be used to demodulate the signal. The electronics may demodulate the electrical signal by mixing the signal with periodic waveforms having frequencies corresponding to the modulation frequencies and twice the modulation frequencies. The modulation frequencies are selected such that at least one of the second harmonic frequencies associated with the modulation frequencies is interleaved in a non-interfering manner within the corresponding set of first harmonic frequencies. Preferably, the modulation frequencies are selected such that at least one of the first harmonic frequencies is interleaved in a non-interfering manner within the corresponding set of modulation frequencies. The hydrophone for sensing the acoustic signals is able to operate at pressures of at least 5,000 psi and temperatures of at least 130 degrees Celsius. The hydrophone may be housed in a cable having a diameter of less than about 1.5 inches. The hydrophone's sensor preferably includes a reference mandrel, two sensing mandrels, and a telemetry can, all of which are aligned in a coaxial, end-to-end configuration to reduce the profile of the hydrophone. Flexible interlinks having grooves therein for receiving optical fiber join the mandrels together. The reference mandrel and sensing mandrels advantageously have hemispherically-shaped endcaps, permitting them to operate at high pressure.

摘要： Light from a master laser is divided into multiple beams. Each of the beams is imaged onto a slave laser in a slave laser array. The multiple beams injection lock the frequency of each laser in the slave laser array to the frequency of the master laser. Some of the output light from the array of slave lasers is directed onto an optical wavefront measurement sensor which measures spatial variation in light phase and intensity. A computer responsive to the output of the optical wavefront measurement sensor controls the injection current to each laser in the slave laser array to adjust dynamically the relative phase of each laser in the array so as to synthesize a desired wavefront.

摘要： A retracting needle syringe is described which allows safe and easy disposal of a syringe and prevents re-use of the syringe by destroying the plunger rod and needle hub and retracting the needle into the plunger rod. Once the safety feature is activated, positive or negative pressure in the barrel to draw out medication is defeated. The retracting needle safety feature requires only an increase of force along the same line of action as the injection stroke. This allows for safe, one-handed injection, which is critical in some situations. The retracting needle syringe of the present invention also minimizes the amount of wasted medication because the plunger rod incorporates a plunger tip that occupies the entire volume inside the barrel. Because the retracting needle syringe uses standard luer-lok fittings, it can be used with a variety of standard needles that do not have retracting cannula. This gives the healthcare professional or patient the ability to use a large gauge needle to fill the syringe from a vial or other container before attaching the safety needle for injection. Lastly, the plunger can be completely encapsulated by the barrel upon activation of the retracting needle syringe safety feature which will prevent re-use of the syringe and allow for safe and easy disposal.
摘要翻译：描述了一种缩回针注射器，其允许安全且容易地处置注射器，并且通过破坏柱塞杆和针座并将针收回到柱塞杆中来防止注射器的再次使用。一旦激活了安全功能，就可以消除桶内出现药物的正压或负压。回缩针安全功能仅需要沿着与注射冲程相同的作用线的力的增加。这允许安全的单手注射，这在某些情况下是至关重要的。本发明的回缩针头注射器还使浪费的药物的量最小化，因为柱塞杆包括占据桶内的整个体积的柱塞头。因为回缩针头注射器使用标准的路厄 - 洛克配件，它可以与不具有回缩插管的各种标准针一起使用。这给予医疗保健专业人员或患者在附加用于注射的安全针之前使用大型针头从小瓶或其他容器填充注射器的能力。最后，在启动回针针头安全特征时，柱塞可以被筒完全包封，这将防止再次使用注射器，并允许安全和容易的处置。

摘要： A surgical scalpel includes an elongate handle that has a proximal end, a open distal end and sidewalls that define an upwardly open cavity with a bottom with an open void therein. The sidewalls each have an elongate channel therein. The scalpel of the invention includes a cartridge that is removably retained within the cavity. The cartridge includes a shield. The cartridge has a blade holder with a proximal end and a distal end mounted within the shield for slidable movement between a proximal and a distal position. There is a latch on the blade holder for engaging the handle and the shield to retain releasably the blade holder in the distal position and the proximal position. The scalpel has a blade fixedly attached to the blade holder so that when the blade holder is in the distal position, the blade projects distally from the handle. When the blade holder is in the proximal position, the blade is within the shield and the handle and thus substantially protected from inadvertent exposure.

摘要： A scalpel of the present invention includes an elongate handle defining a longitudinal axis and having a proximal end and a distal end. The scalpel of the invention further includes a cartridge that is removably mounted to the handle. The cartridge has blade holder with a proximal end and a distal end with a blade fixedly attached that is disposed so that the blade projects distally outwardly when the cartridge is mounted to the handle. The cartridge also includes a shield that is slidably mounted onto the blade holder for movement between a distal position where the shield substantially prevents inadvertent access to the blade and a proximal position where the shield substantially surrounds a portion of the handle and the blade is exposed for use. The cartridge is releasably mountable on the handle. The shield is substantially prevented from movement to the proximal position unless the cartridge is mounted on the handle and not dismountable from the handle unless the shield is in the distal position.
