Patent number: 10459419Abstract: A web jam detector and associated method are provided for detecting a jam of feedstock material in a scrap chopper. A web detection bar, mounted to the scrap chopper, includes a plurality of web detection fingers. The plurality of web detection fingers are made of an electrically conductive material, are electrically connected to and extend outwardly from the web detection bar, and are positioned to contact the feedstock material when the scrap chopper is in a closed position. A web jam detection circuit is electrically connected to the web detection bar. In operation, the web jam detection circuit supplies direct current electricity to the web detection bar and generates feedback signals based on a voltage of the web detection bar. The feedback signals are indicative of the presence or absence of the feedstock material at the plurality of web detection fingers.Type: GrantFiled: February 6, 2018Date of Patent: October 29, 2019Assignee: FCA US LLCInventors: Brian D Campbell, Jesse C James, Bruce M Berriman

Patent number: 5745071Abstract: The method and apparatus precisely identifies and locates an object which resonates in response to signals of at least one and, more typically, two resonant frequencies. The locating apparatus includes a transmitter for concurrently transmitting signals having a resonant frequency and signals having a non-resonant frequency toward the resonant object. The locating apparatus also includes at least two receivers for receiving reflected signals having the resonant frequency and the non-resonant frequency. The locating apparatus further includes a signal processor for locating the resonant object based upon the reflected signals detected by the receivers. The signal processor has multiple channels, one of which is associated with each receiver, for separately processing the reflected signals received over time by each of the receivers.Type: GrantFiled: March 10, 1997Date of Patent: April 28, 1998Assignee: McDonnell Douglas CorporationInventors: James B. Blackmon, Jr., Jesse C. James

Patent number: 5682168Abstract: One or more antenna elements are submerged beneath a faired cover over a roof supporting member of a motor vehicle or hidden behind or as part of the front grill. Usually a conductive support extends behind the antenna elements and are electrically isolated therefrom to form the ground plane of the antenna. In some cases the antennas can be the structural members electrically isolated from the remainder of the body, but physically connected thereto. RF absorbers may be positioned spaced from radiating antenna elements to prevent antenna cross talk and exposure of occupants of the vehicle to high RF power densities. The antenna elements are especially useful in providing collision avoidance radar.Type: GrantFiled: May 20, 1996Date of Patent: October 28, 1997Assignee: McDonnell Douglas CorporationInventors: Jesse C. James, James B. Blackmon, Jr.

Patent number: 5596324Abstract: Microwave devices incorporate at least one photosensitive baffle that is selectively illuminated changing the baffle's electronic characteristic from being transparent to being reflective of microwave energy. The baffle serves as a gate, tuning element, reflector and the like. Various forms of photosensitive baffles and microwave devices are presented.Type: GrantFiled: December 9, 1994Date of Patent: January 21, 1997Assignee: McDonnell Douglas CorporationInventor: Jesse C.

Patent number: 5548461Abstract: Placed in electrical circuit in shunt of the electrodes that supply current to a protected device and optically coupled to the location in the protected device where an electric arc is most likely to occur, a photosensitive device, responsive to illumination created by such an electric arc, switches to a conductive state, thereby short circuiting the electrodes feeding current to the arc and the arc is quickly extinguished.Type: GrantFiled: October 5, 1994Date of Patent: August 20, 1996Assignee: McDonnell Douglas CorporationInventor: Jesse C.

Patent number: 5473332Abstract: Improvement of radar sign-to-noise ratio and detection sensitivity in radar systems is achieved by methods employing the subtraction of the unwanted radio frequency interference, RFI, or "clone" signals thereof, from the total received signal. The Clone signals are appropriately adjusted in phase and amplitude, and are obtained from an auxilliary broad beam antenna or from a delayed sample from the system's principal antenna. When multiple RFI signals at different frequencies are present, the entire receive band is subdivided into a plurality of frequency sub-ranges.Type: GrantFiled: August 10, 1994Date of Patent: December 5, 1995Assignee: McDonnell Douglas CorporationInventors: Jesse C. James, James B. Blackmon, Jr.

Patent number: 5459442Abstract: An adjustable phase shifter is formed of an RF transmission line having an internal cavity, in which the phase shift produced is determined in part by a mound of flowable dielectric material in the internal cavity. An inlet tube defines a chute for dispensing the dielectric material into the internal cavity and a capped outlet tube connected to a bottom end of the internal cavity defines another gravity chute through which the dielectric material is removed to lower the height of the mound, when the cap is removed from the tube. The electrical length of the phase shifter is increased with addition of dielectric material and decreased with removal thereby varying the effective length of the RF transmission line and the phase shift produced on the RF that propagates therethrough.Type: GrantFiled: January 23, 1995Date of Patent: October 17, 1995Assignee: McDonnell Douglas CorporationInventor: Jesse C.

Patent number: 5406290Abstract: An interceptor's point of impact on a targeted missile is quickly revealed in the milliseconds preceeding and following the impact by illuminating the target with radar signals at a high pulse repetition rate and observing the reflected radar echoes on an A-scope display. The position within the returned radar echo of a double echo and related changing phenomenon indicates the point of impact. Failing intercept, the miss distance is computed from the relative slant ranges to the targeted missile, the interceptor, and the double echo. The type warhead killed is revealed by a spectrograph slaved to the radar's antenna. Various techniques assist with the interpretation of the displayed patterns, including subtraction of previously stored patterns and display of the difference, display of characteristic patterns of various known missiles and interceptors stored in "look up" tables, and neural networks.Type: GrantFiled: May 2, 1994Date of Patent: April 11, 1995Assignee: McDonnell Douglas CorporationInventors: Jesse C.
