Patent number: 8964172Abstract: The present disclosure describes an apparatus including a composite panel. The apparatus includes a first composite panel including a first optical fiber embedded therein, the first optical fiber being arranged in a pattern, and a first input port connected to a first end of the first optical fiber, the first input port configured to receive an optical signal from an optical time domain reflectometer. The optical time domain reflectometer is configured to send the optical signal through the first input port and measure a strength of a reflected optical signal that is reflected back from the first optical fiber, wherein the strength indicates a measured optical impedance of the first optical fiber. A measured optical impedance that is substantially the same as a baseline optical impedance for the fiber indicates no damage, while a measured optical impedance that differs from the baseline optical impedance by a predetermined threshold indicates damage.Type: GrantFiled: September 27, 2010Date of Patent: February 24, 2015Assignee: Rockwell Collins, Inc.Inventors: Arlen E. Breiholz, Peter J. Morgan, Thomas A. Potts

Patent number: 8441383Abstract: The present invention is directed to a photonic digital-to-analog converter (pDAC) system. The system may include a mode locked laser, an optical splitter connected to the laser, and a plurality of reflective semiconductor optical amplifiers connected to the splitter. The mode locked laser transmits a digital optical pulse train to the splitter. The splitter splits an optical pulse of the digital pulse train into multiple optical pulses and provides the multiple optical pulses to the amplifiers via a plurality of optical paths, at least two of the optical paths having different path lengths. The amplifiers amplify the multiple optical pulses and provide the amplified multiple optical pulses to the splitter. The splitter outputs an analog optical pulse train derived from the amplified multiple optical pulses. The system provides for faster sampling rate and lower jitter than Electrical Digital-to-Analog converter (eDAC) systems.Type: GrantFiled: March 11, 2011Date of Patent: May 14, 2013Assignee: Rockwell Collins, Inc.Inventor: Peter J.

Patent number: 5108167Abstract: A laser signal coupling device one embodiment of which comprises a transmitter where a laser diode is coupled to a single mode fiber optic cable through the use of a lens whose position relative the diode is kept constant but whose length is adjusted to obtain a beam waist for the focused beam at some predefined point such as inside the end of the fiber optic cable. Such a positioning of the beam waist can increase the yield by reducing the effect of alignment variations in axial, radial and angular directions as well as reduce noise from fiber end surface reflections. The same concept may be used to accurately focus signaling received from an optic cable, in a surface of a signal detector. Further, the concept may be used for focusing between optic cable of different types such as converting from multi-mode to single-mode fiber optic cable.Type: GrantFiled: October 31, 1990Date of Patent: April 28, 1992Assignee: Rockwell International CorporationInventors: Pramode Kandpal, Peter J.

Patent number: 4967146Abstract: Precisely controlled grooves are formed in a semiconductor wafer as part of a total photolithographic process of producing the circuitry and the V-grooves for precise registration of the circuitry relative the edges of the individual chips of the wafer. The same registration facilitates automated electrical testing of each of the chip circuits on the wafer prior to the controlled disassembly of the array of chips into individual die. The design of the electrical connections on the array before disassociation into individual die also facilitates a mass burn-in of the circuits which burn-in tends to identify and eliminate parts subject to early failure.Type: GrantFiled: May 15, 1989Date of Patent: October 30, 1990Assignee: Rockwell International CorporationInventors: Peter J.

Patent number: 4796465Abstract: Large turbomachines such as steam turbines and gas turbines will have an operational lifetime which may be measured in terms of decades. During the operational lifetimes it is desirable to monitor the condition of major parts of the turbomachine such as rotors and rotor wheels. Procedures are available for non-destructive testing of major turbomachine parts but it is desirable to affirm the actual condition of a turbomachine rotor by a sacrificial test of a speciment taken from a forging from which the actual turbomachine part was made. Further, it is desirable that the specimen be in service with the turbomachine part so as to obtain an accurate operating experience. To this end, a specimen taken from a turbomachine forging is affixed to a finished turbomachine part and then run with the machine for latter removal and test.Type: GrantFiled: April 28, 1987Date of Patent: January 10, 1989Assignee: General Electric CompanyInventors: Diether E. Carreno, Peter J. Morgan

Patent number: 4393371Abstract: In an analogue to digital converter, the analogue signal applied thereto is sampled at successive time intervals and at each sample a digital signal is produced and the time interval between successive samples is not necessarily constant but is dependent upon the rate of change of amplitude of the analogue signal during said time interval. The digital signals may be applied to a counter to produce data representative of the time interval between successive samples and also to indicate whether the analogue signal has increased or decreased between successive samples. This data may then be recorded in a manner to provide substantially constant recording density.Type: GrantFiled: May 18, 1981Date of Patent: July 12, 1983Assignee: Morgan-Smith Electronics Ltd.Inventor: Peter J.
