  • Publication number: 20050110496
    Abstract: Magnetometry and pulsed electromagnetic radiation (EM) may be employed during a same survey pass by synchronously interleaving the collection of magnetometer data with pulses from EM sensors. For example, one or more magnetometers may be sampled between pulses of one or more EM coils such that the data from the one or more magnetometers is substantially free of artifacts from the pulsed EM radiation. A detection system may include a vehicle capable of locomotion over a surface of earth, a mount coupled to the vehicle, the mount including at least one magnetometer, at least one EM sensor adapted to produce pulses of EM radiation, and a controller adapted to interleave collection of data from the at least one magnetometer between the pulses of EM radiation.

  • Publication number: 20050029727
    Abstract: A vise used for holding and stabilizing a wide variety of work object shapes by means of conformable spring action jaws faces. The jaws faces are designed to be interchangeable to accommodate delicate or heavy-duty work. Dual ratchet mechanisms and a cam-driven piston provide both a quick and convenient method of closure that maintains precise and significant levels of clamping force. If desired, lockout features are included that defeat the spring action of the jaws and allows the vise to act more like a traditional vise. In addition, interchangeable smooth faced jaws allow the vise to function as a traditional vise.

  • Patent number: 6689086
    Abstract: An ultrasound delivery catheter equipped and configured for concurrent delivery of drugs or therapeutic agents. The catheter comprises an elongate pliable catheter body having an ultrasound delivery member or wire extending longitudinally therethrough. A drug/therapeutic agent infusion lumen also extends longitudinally through the body of the catheter and opens distally through one or more outflow apertures at or near the distal end of the catheter body. The drug/therapeutic agent outflow apertures are preferably positioned and configured to cause the drug or therapeutic agent to flow in direction(s) non-parallel to the longitudinal axis of the catheter. The delivery of ultrasound through the catheter, concurrent with infusion of drug or therapeutic agent therethrough, will cause the drug or therapeutic agent to be disseminated or dispersed by the ultrasonic vibration or movement at the distal end of the catheter.

  • Patent number: 6506621
    Abstract: In a method for producing a diaphragm sensor array having a semiconductor material substrate on which a plurality of planar diaphragm regions is arranged as a carrier layer for sensor elements, the planar diaphragm regions are thermally decoupled from one another by crosspieces made of a material having clearly better heat conductive properties compared to the diaphragm regions and the lateral surroundings of the crosspieces. Masking for a subsequent step for producing porous semiconductor material is applied at the locations of the semiconductor material substrate at which the crosspieces for the thermal decoupling are formed, and the semiconductor regions not protected by the masking are rendered porous and the diaphragm regions are produced thereupon. Instead of using porous silicon, a plasma etching process may be performed from the backside of a semiconductor material substrate. In particular, high integration densities of diaphragm sensors may be achieved with both methods.

  • Publication number: 20020094435
    Abstract: A micromechanical component and a method of producing same are described; the component has a supporting body, in particular a silicon body, and a membrane which is connected to the supporting body and is unsupported at least in some areas. The membrane is also provided with at least one stabilizing element in an unsupported area in some areas of the surface.

  • Patent number: 6077252
    Abstract: An improved single- or multiple-dose syringe having a conventional housing and an improved plunger configuration carrying a medicament- or saline-filled cartridge the contents of which are sequentially dispensed after the dispensing of a volume of a drawn-up primary fluid. A method for sequential administration of medicinal fluids using the improved syringe is also a part of the invention.

  • Patent number: 5790893
    Abstract: A communication adapter connected between a communication line and a host processor segments a received data frame by storing the received data in a buffer chain made up of equal length buffers. As each buffer is filled, the adapter interrupts the host. The host moves the data stored in the filled buffer into its own storage. It interrupts the adapter so that the buffer can be returned to the chain of free buffer and completes transmission protocol processing before the entire frame is received. If the frame has been received without error or buffer overrun it is delivered to the user immediately after transfer of the last buffer.

  • Patent number: 5540656
    Abstract: An ultrasonic angioplasty device comprising an elongate ultrasound transmission member having a proximal end attachable to an ultrasound generating device and a bulbous distal head or probe formed on the distal end thereof for effecting ablative treatment of an occluding lesion. The ultrasound transmission member may be formed of one or more superelastic metal alloys such as NiTi (50 at. % Ni). A guidewire lumen may be formed in the distal head or probe to permit passage of a guidewire therethrough. Portions of the ultrasound transmission member may be curved or bent. Portions of the ultrasound transmission member may be tapered or narrowed. One or more surface disruptions may be formed on the distal head or probe to improve treatment efficacy. An increased hardness coating or outer skin may be formed on the ultrasound transmission member. The device of the present invention may be incorporated into an angioscopic device.
