  • Publication number: 20210068249
    Abstract: A PCB laminate material includes at least one polymer layer and at least one inorganic layer, such that the PCB laminate material has a dielectric loss tangent of less than 6×10?3 at 10 GHz (or higher frequency). The inorganic layer or layers of the PCB laminate material may comprise silica-based materials (including silica fabrics), low-loss glass with a dielectric loss tangent of about 0.006 at 10 GHz (or higher frequency), glass-ceramics, or ceramic materials (e.g., alumina). PCB laminate materials may also include at least one fluoropolymer layer. PCB laminate materials described herein combine good dielectric performance (i.e., low dielectric loss), dimensional stability at elevated temperature (e.g., at 260° C. for 30 seconds), and sufficient mechanical strength to permit handling during production. Printed circuit boards comprising the PCB laminate materials and methods for making the same are also disclosed herein.

  • Patent number: 9247629
    Abstract: An apparatus includes an electromagnetic waveguide; an iris structure providing an iris in the waveguide. The iris structure may define an iris hole, a first iris slot at a first side of the iris hole, and a second iris slot at a second side of the iris hole. A plasma torch is disposed within the iris hole. An electric field in the waveguide changes direction from the first iris slot to the second iris slot. The plasma torch generates a plasma which is substantially symmetrical around a longitudinal axis of the plasma torch, such that the plasma may have a substantially toroidal shape. In some embodiments, a dielectric material is disposed in the iris hole, outside of the plasma torch. In some embodiments, the height of at least one of the iris slots is greater at the ends thereof than in the middle.

  • Patent number: 8149420
    Abstract: A metrology system is provided comprising a diffraction grating mounted on the object, and an interferometer head operable to direct at least one measurement light beam towards the grating at a non-zero angle of incidence. With a single first separation in the second direction between the object and the interferometer head, respective displacement measurements are made at known displacements of the object. From the displacement measurements are generated respective original calibration values, each pertaining to a respective one of the known displacements. With a second separation in the second direction between the object and the interferometer head, a displacement of the object is measured. The measured displacement is corrected using an offset calibration value derived from at least one of the original calibration values and pertaining to at least one offset displacement, offset from the measured displacement.

  • Patent number: 7545507
    Abstract: A displacement measurement apparatus includes a light source, a splitter grating, a measurement grating, and first a second detector arrays. The splitter grating splits a light beam into first and second measurement channels that each illuminates the measurement grating. The first and second measurement channels split into 0th and 1st order diffraction products at the measurement grating in a first pass and recombine at the measurement grating in a second pass before being measured at the first and second detector arrays.

  • Patent number: 7440113
    Abstract: An apparatus and method for measuring displacement includes a light beam directed to an interferometer core that splits the light beam into first and second component beams. The first component beam is directed to a diffraction grating at approximately a Littrow angle. A diffraction is received by the interferometer core and is combined with the second component beam. The combination of the first and second component beams is measured to determine displacement of the diffraction grating.

  • Patent number: 7384733
    Abstract: The invention provides a novel development of the conventional patch clamp technique for measurement of whole cell electrical activity. The invention provides for one or more cell or cells to be suspended in a liquid medium at a liquid/air interface (by virtue of the effect of surface tension at the interface) whereby the cell or cells are accessible at the interface to a microstructure electrode (such as a pipette tip) to which a cell can attach to form an electrical seal, for the purpose of whole cell voltage clamp recording. According to the invention the electrode can be caused to form a high resistance electrical seal with a cell suspended in the liquid at the liquid/air interface without the need to press the cell against a solid support surface. The invention also provides apparatus for carrying out the interface patch clamp technique and control logic for operating a computer to carry out the interface patch clamp technique.

  • Patent number: 7286579
    Abstract: Adjustment of a tunable external-cavity laser is simplified by incorporating a mount that includes a base, a main body, a reflecting surface, a diffracting surface and a hinge coupling the main body to the base. The laser additionally includes a light source, a converging lens located to receive light from the light source, a tuning mirror and a pivoting arm on which the tuning mirror is mounted. The main body is bounded in part by two plane, external surfaces orthogonal to a common reference plane and angularly separated from one another by an angle. The reflecting surface has a spatial orientation defined by one of the external surfaces and is arranged to receive light from the lens. The diffracting surface has a spatial orientation defined by the other of the external surfaces, and diffracts light received from the reflecting surface towards the tuning mirror. The hinge is located opposite the angle and parallel to the reference plane.
