Publication number: 20240165764Abstract: A method of machining ceramic matrix composite components includes providing an ultrasonic vibration tool having a tool tip, and exciting the tool by providing a control current, such that the tool tip is repeatedly vibrated towards and away from a ceramic matrix composite workpiece. A slurry feed is supplied including abrasive particles to a surface to be machined by the tool tip. A vibration amplitude of the tool tip is controlled by sensing load on the tool and communicating with a computing device. The computing device controls the vibration amplitude of the tool tip. The computing device is provided with at least one memory programmed with historic data, and is operable to modify the vibration amplitude signal being sent to the tool, and comparing resulting load levels due to the change in vibration amplitude signals, and storing the change in vibration amplitude signals at the memory.Type: ApplicationFiled: November 23, 2022Publication date: May 23, 2024Inventors: Zhigang Wang, Andrzej E.

Patent number: 6651016Abstract: An analog signal is digitized by an analog-to-digital (A/D) converter clocked by a periodically jittery clock signal. Elements of the digital data sequence (vector) output of the A/D converter are sorted into a set of smaller vectors according to clock signal jitter phase and each of the smaller vectors is then separately subjected to Fourier transform and time shift functions. The resulting vectors are then processed to produce an output vector representing the frequency spectrum of the analog signal.Type: GrantFiled: December 21, 2001Date of Patent: November 18, 2003Assignee: Credence Systems CorporationInventors: Jonathan M.

Patent number: 6279484Abstract: A mechanism is disclosed for actuating a switch guide beam swinging laterally between two or more fixed guide beam ends, in order to make a route selection for a beam guided vehicle. The moving guide beam pivots distantly of the primary fixed guide beam end to create a gap spanned by an intermediate suspended channel plate guide segment that provides substantially two equal lateral deflections to the moving vehicle for a route diversion in a storage yard or repair shop area. The mechanism for high speed or main line operation has two additional channel plate guide segments slidably guided at each end of the guide segment centrally affixed on the straddle beam and pivoted at the primary beam fixed end and the merge point on the radially moving swing guide beam to provide four substantially equal lateral deflections to the moving vehicle when a route diversion is required.Type: GrantFiled: June 13, 2000Date of Patent: August 28, 2001Inventor: John B.

Patent number: 6129028Abstract: A mechanism for steering a beam guided vehicle having four steerable wheels linked to a centrally located steering trolley guided by an electrified T-shape beam mounted on a structural roadbed. A trolley flexibly propelled by the vehicle follows the guide beam to actuate the steering of the wheels. The trolley is quickly detachable by drop-pit access for rapid change-out to periodic off vehicle servicing. Two steering arm sensor posts engaging two sockets in the repositioned trolley guarantee interchangeability of standardized repaired units.Type: GrantFiled: October 13, 1998Date of Patent: October 10, 2000Inventor: John B.

Patent number: 6014587Abstract: An electro-convulsive therapy (ECT) system includes both hardware and software safety detectors and monitors generator that generates a pulse train of a plurality of pulses with parameters specified by the user. The safety monitors monitor these user-specified parameters as well as other important pulse parameters both during treatment of a patient and prior to treatment in order to ensure that the system is operating according to specification and, therefore, will not injure the patient. The pulse generator is responsive to the safety monitors in that if any of the safety detectors detect a parameter that is out of tolerance, the safety monitor disables the pulse generator so that no further pulses are delivered to the patient. The safety detectors detect the plurality of pulse characteristics including pulse width, frequency, voltage, current, treatment duration, as well as energy.Type: GrantFiled: September 18, 1997Date of Patent: January 11, 2000Assignee: Mecta CorporationInventors: John B.

Patent number: 4283122Abstract: Apparatus for streaking a beam of light employing a crystal in which an electromagnetic wave pulse induces a synthesized traveling lens. Surfaces on opposite sides of the crystal act as light reflectors to create multiple cross-reflections of the beam relative to the crystal, thus to enhance the lensing effect of the crystal. Production of the electromagnetic wave pulse is coordinated with impingement of a beam of light, and the geometry of parts is arranged whereby each coherent wave front in the beam, as it passes multiple times through the crystal, on each such passing encounters the same substantially constant lens condition which has been induced in the crystal.Type: GrantFiled: October 29, 1979Date of Patent: August 11, 1981Assignee: Oregon Graduate Center for Study and ResearchInventors: Richard A. Elliott, Gail A. Massey, John B. Shaw
