  • Patent number: 7987717
    Abstract: For more efficient and energy-saving drying of ink and/or coating films in printing machines, the drying or hardening process must be better monitored. Therefore a method is proposed for determining the degree of hardening of one or more printed ink and/or coating films on a substrate that was coated in an intaglio, flexographic or offset printing process. The degree of hardening or drying due to the hardening or drying process is determined indirectly via the change of mechanical and/or viscoelastic properties of the ink and/or coating films on the substrate. An ultrasound measurement is used for this purpose.

  • Patent number: 7987714
    Abstract: A disc resonator gyroscope (DRG) and method of manufacture. The DRG has a surrounding pattern of bond metal having a symmetry related to the symmetry of a resonator device wafer that enables more even dissipation of heat from a resonator device wafer of the DRG during an etching operation. The metal bond frame eliminates or substantially reduces the thermal asymmetry that the resonator device wafer normally experiences when a conventional, square bond frame is used, which in turn can cause geometric asymmetry in the widths of the beams that are etched into the resonator device wafer of the DRG.

  • Patent number: 7987693
    Abstract: Method and apparatus for measuring the coefficient of rolling friction or speed of a horizontal surface over which a round object is rolled such as a putting green encountered in the game of golf. The method includes a device for launching a ball across the surface at a constant and consistent velocity. An included timing device is triggered to start counting the elapsed time when the ball exits the launching device and continues counting until the ball has decelerated to a stop. At the instant the ball ceases moving the timer is triggered to terminate the count. The time required for a body with a specific velocity to come to rest after experiencing constant deceleration is determined by the laws of motion. The coefficient of friction or “speed” of the green which is proportional to the amount of deceleration may then be calculated. This time measurement is therefore sufficient to determine the speed of the green surface which may be reported as an equivalent “stimp” value.

  • Patent number: 7987720
    Abstract: A system and method for detecting leaks in substantially closed objects, such as automobiles, airplanes, tanks, and other vehicles, using an ultrasonic transmitter and one or more ultrasonic sensors or receivers supported on a frame. Ultrasonic amplitude readings obtained from the sensor or sensors are processed to determine if they are representative of a defective or leaking object. The position of the leak may be determined by examining the readings from individual sensors. The system is particularly well-adapted for use in detecting defects and leaks in automobiles on an assembly line without interrupting the assembly process or damaging the automobile.

  • Patent number: 7987718
    Abstract: Forces are applied to a device under test and its mechanical response is measured by a laser vibrometer (50). The forces are applied without making physical contact with the device by producing an acoustical force with an ultrasonic beam (54). One embodiment employs two confocal transducers (56, 58) that produce beams that flood the device. Drive signals modulate the ultrasonic beams to produce the desired forces, and the use on a plurality of ultrasonic beams enable selective excitation of different modes of vibration of the object (7).

  • Patent number: 7984641
    Abstract: A method for evaluating a lubrication containment system is set forth herein. In one lubrication containment system, a seal runner can be fixed to the rotatable structure and seal against a static radial seal supported by the sump housing. The method also includes the step of rotating the structure relative to the sump housing. The method also includes the step of directing test fluid to the structure inside the sump housing. The method also includes the step of quantifying an accumulation of test lubricant at the seal runner during rotation by omitting the radial seal from the lubrication containment system. As a result, test lubricant can pass out of the sump housing. The amount of test lubricant that passes out of the sump housing, past the location where the seal runner would be or would have been, corresponds to the amount of lubricant that accumulates at the seal runner during operation in the field.
