Application number: 20140236500
Abstract: The invention relates to a method for processing an ultrasonic analog signal (10) representing a reflected ultrasonic wave, wherein the ultrasonic analog signal (10) is fed in a parallel manner into at least two signal paths (A;B) and the ultrasonic analog signal is supplied in each signal path (A;B) to respective amplifiers (20A;20B) whose gains are different from one another. The ultrasonic analog signals (11;11?) which have thus been amplified differently are supplied in each signal path (A;B) to a respective A/D converter (30A;30B) which converts the amplified ultrasonic analog signals (11; 11?) into digital ultrasonic data (12;12?), from which a combined digital ultrasonic signal (15) is reconstructed after further processing steps. According to the invention, a decomposition of the digital ultrasonic data (12; 12?) is carried out in each signal path (A;B) by the first level of a wavelet filter algorithm, and the wavelet coefficients are altered by a threshold analysis.

The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances in inches by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil in inches. The X and Y values are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The airfoil profile sections at Z distances may be joined smoothly with one another to form a complete airfoil shape.

Patent number: 8810636
Abstract: A control signal for selectively outputting a frame of image data can be initiated using an inspection apparatus, and an inspection apparatus can process one or more frames of image data for determining a motion parameter. Responsively to the processing, the inspection apparatus can selectively output a frame of image data, improving the quality of a frame of image data output subsequently to an initiation of a control signal to selectively output a frame of image data.

Patent number: 8807959
Abstract: A condition monitoring system for use with a reciprocating device. The condition monitoring system includes at least one pressure sensor that is configured to sense a pressure within the reciprocating device. At least one vibration sensor is configured to sense a vibration of the reciprocating device. A protection system is communicatively coupled to the pressure sensor and the vibration sensor. The protection system is configured to calculate a stiffness value of the reciprocating device based on the sensed pressure within the reciprocating device and the sensed vibration of the reciprocating device.

Patent number: 8810117
Abstract: A spark plug includes a center electrode and a ground electrode. The center electrode is arranged relative to the ground electrode in such a way that the spark gap extends between the ground electrode and the center electrode. The spark gap is surrounded by a wall, wherein the wall has a recess or hole, which is designed in such a way that a feeler gauge can be inserted between the center electrode and the ground electrode.

Patent number: 8808203
Abstract: A capacitive uterine contraction sensor includes an insulating substrate, a first electrode disposed on one side of the substrate, and a second electrode positioned on the first side of the substrate in a spaced relation to the first electrode. The second electrode is configured to move toward or away from the first electrode. The sensor may also include a conductive standoff sandwiched between the substrate and the second electrode for maintaining the second electrode in spaced relation to the first electrode. The conductive standoff is electrically coupled to the second electrode and electrically isolated from the first electrode. Alternatively, the second electrode may include a spring mechanism used in conjunction with a standoff to maintain the second electrode in spaced relation to the first electrode. The spring mechanism is electrically isolated from the first electrode and enables the second electrode to move toward or away from the first electrode.

Patent number: 8808944
Abstract: A method for storing holographic data, said method comprising: step (A) providing an optically transparent substrate comprising a polymer composition and a light absorbing chromophore, said polymer composition comprising a continuous phase and a dispersed phase, said dispersed phase being less than about 200 nm in size; and step (B) irradiating a volume element of the optically transparent substrate with a holographic interference pattern, wherein the pattern has a first wavelength and an intensity both sufficient to cause a phase change in at least a portion of the dispersed phase within the volume element of the substrate to produce within the irradiated volume element refractive index variations corresponding to the holographic interference pattern, thereby producing an optically readable datum corresponding to the volume element.
