Northrop Grumman has been granted several new patents.
Patent for Auto Tier II
The abstract states: “A system for providing an estimate of far-field radar cross-section (RCS) measurements of an aircraft. The system includes a plurality of automatic guided vehicles (AGV) each including a robot arm and a radar unit selectively mounted thereto and being interchangeable with a camera. Each AGV includes an AGV controller for controlling the robot arm, the radar unit and the camera so as to cause the radar unit to provide the near-field RCS measurements or the camera to provide images of the aircraft. The system further includes a real time signature diagnostic sub-system (SDS-RT) responsive to the near-field RCS measurement signals from the radar units and the images from the cameras in real time, and an SDS controller responsive to re-configured near-field RCS measurement signals and images from the SDS-RT and configuring the near-field RCS measurement signals and the images into the estimate of the far-field RCS measurements of the aircraft.”
Patent for Bias Boosting Circuit for Amplifier
The abstract states: “An amplification system can include a bias booster circuit and an amplifier that amplifies an input signal to drive a load. The bias boosting circuit can include a negative bias booster that applies a charge to an input node of the amplifier in response to a negative half-cycle of the input signal that exceeds a boost threshold level. The bias boosting circuit can also include a positive bias booster that discharges the input node of the amplifier during a positive half-cycle of the input signal that exceeds the boost threshold level. The discharging by the positive bias booster is slower than the charging by the negative bias booster to induce a bias voltage increase from a quiescent bias voltage on the input node of the amplifier.”
Patent for Voltage Controlled Tunable Filter
The abstract states: “An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, .epsilon.r that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.”
Patent for Reciprocal Quantum Logic Circuit Simulation System
The abstract states: “One example includes an RQL circuit simulation system. The system includes a circuit design tool that facilitates user inputs to design an RQL circuit design comprising at least one predetermined RQL circuit design component. The system also includes a memory system that stores the RQL circuit design and an RQL component library comprising predetermined RQL circuit design components from which the at least one predetermined RQL circuit design component is selected. Each of the predetermined RQL circuit design components includes predetermined RQL component metrics associated with performance of the respective one of the predetermined RQL circuit design components. The system also includes a circuit simulator configured to compile performance metrics associated with the RQL circuit design based on the predetermined RQL component metrics associated with the respective at least one of the predetermined RQL circuit design components and to simulate the RQL circuit design based on the performance metrics.”
Patent for Microelectronic RF Substrate
The abstract states: “An exemplary electronic assembly includes a planar semiconductor substrate having a front side with semiconductor components and a back side that includes one recess extending inwardly. One of an isolator and circulator is formed as part of the planar semiconductor substrate and includes one magnetic ferrite disk mounted within the one recess within the thickness of the planar semiconductor substrate. The one of an isolator and circulator has at least input and output ports. The input port is disposed to receive a radio frequency signal to be coupled with low insertion loss to the output port while providing high insertion loss to other radio frequency signals attempting to propagate from the output port to the input port.”
I’m not adding NOC to the long-term portfolio because it has not pulled back yet and the Twiggs Money Flow is trending lower. NOC stock has the feel of arriving to late to the party and you’d have to chase the stock to take an entry. Chasing anything in this market is deadly.
Disclosure: I have no position in NOC.
