Patent number: 10386383Abstract: A waveguide arrangement for measuring the speed of a projectile during passage through a weapon barrel arrangement includes a main waveguide and at least one auxiliary waveguide. The main waveguide has a cross-section suitable for the passage of the projectile. The auxiliary waveguide extends adjacent to the main waveguide and is connected to the main waveguide via an opening. An isolator is arranged in the auxiliary waveguide. The waveguide arrangement is particularly suited for large-caliber ordinance and has at least one coupler extending at least partially in the isolator. The speed of the projectile in the main waveguide is measured at a frequency below the limiting frequency. The transmitting coupler is arranged at a spacing distance from the muzzle in order to prevent an exit of the generated signal from the weapon barrel arrangement.Type: GrantFiled: February 2, 2016Date of Patent: August 20, 2019Assignee: Rheinmetall Air Defence AGInventor: Henry Roger Frick

Patent number: 8305071Abstract: An apparatus and method for measuring muzzle velocity (V0) of a projectile, which apparatus includes a smooth weapon barrel or firing barrel as a waveguide, a signal generator which is electrically connected via a signal supply line to at least one transmission coupler in order to energize the weapon barrel or firing barrel, and a receiving line for passing on the signals measured at at least one receiving coupler to an evaluation device. If the velocity is measured after the projectile has passed through, the receiving coupler is located between the projectile base and the transmission coupler, while the receiving coupler is between the projectile nose and the transmission coupler when the velocity (V0) is measured before the projectile passes through. The electromagnetic field of the empty weapon barrel is measured without a projectile, in front of the projectile or behind the projectile, or in combination. The muzzle velocity (V0) is then determined from the measured signals.Type: GrantFiled: May 21, 2009Date of Patent: November 6, 2012Assignee: Rheinmetall Air Defence AGInventor: Henry Roger Frick

Patent number: 7903019Abstract: A protective device and protective measure for a radar system is provided that includes an active countermeasure by using passive emitter and/or decoys. Decoys are thereby utilized that function according to the reflection principle. These decoys are thereby radiated by the vehicle's radar. The radiation reflected by the decoys in the direction of the ARM has the same characteristic as the direct radiation from the radar itself. Thus, the ARM is unable to discriminate between decoys and the actual radar.Type: GrantFiled: April 10, 2007Date of Patent: March 8, 2011Assignee: Rheinmetall Air Defence AGInventor: Henry Roger Frick

Publication number: 20050063444Abstract: An optical medium having a cavity that defines a variable gap is provided. The optical medium is used in an optical sensor, laser, and variable frequency resonator, by way of example. The cavity is physically altered in response to changes in a measurable parameter like pressure, temperature, force, flow rate, and material composition. The optical medium is characterized in some embodiments by having a cavity disposed near or within a high Q optical resonator. The optical resonator can be formed by various structures of which Bragg reflector cavities, ring resonators, microdiscs, and microspheres are examples. The optical resonator is preferably coupled to a laser source. The altering of the cavity affects the resonance condition within the optical resonator and thereby the laser signal of the system. If the laser source is a mode locked laser, the repetition rate of the pulse train changes in response to changes in the measurable parameter.Type: ApplicationFiled: November 28, 2001Publication date: March 24, 2005Inventor: Roger Frick

Publication number: 20050062628Abstract: A measurement system includes multiple analog sensor elements and multiple sigma-delta modulators for producing digital outputs. Each sigma-delta modulator receives charge packets from one or more sensor element and charge packets from a shared element (which may be a sensor or a reference element). The sigma-delta modulators are operated synchronously in separate phases, so that the shared element either delivers or does not deliver a charge packet of the sign desired by a sigma-delta modulator only during the phase associated with that sigma-delta modulator.Type: ApplicationFiled: September 19, 2003Publication date: March 24, 2005Inventor: Roger Frick

Patent number: 6520020Abstract: A pressure sensor integrally formed in the shape of a beam around a central channel. The beam has an integral blind end that is pressurized by the fluid. The beam has an opposite end that is shaped to provide a stepped corner with a gap opening at the base of the stepped corner, where the gap and isolated from the fluid. A sensing film in the channel adjacent the blind end has an electrical parameter that varies with pressure and electrical leads that extend from the channel and out the gap. A seal fills the gap around the leads and the seal fills a portion of the stepped corner. The sensor is preferably formed by direct bonding of single crystal alumina layers. Applications include industrial pressure transmitters, aerospace and turbine engine pressure sensing.Type: GrantFiled: January 6, 2000Date of Patent: February 18, 2003Assignee: Rosemount Inc.Inventors: Mark A.

Patent number: 6487912Abstract: A pressure sensor module and method for pre-installation without a converter module. The pressure sensor module is hermetically sealed and can remain undamaged in an installation environment without a converter module. The pressure sensor module can be assembled later with a converter module in the installation environment. The pressure sensor module includes an isolator, a pressure sensor and a circuit that provides a bus for energization, control and a digital pressure output. The bus is connected to contacts in an insulating feedthrough. An integrally formed hermetic external support structure surrounds the pressure sensor and circuit. The hermetic external support structure has a threaded process fluid inlet around the isolator, and a threaded support sleeve supporting the feedthrough.Type: GrantFiled: March 7, 2000Date of Patent: December 3, 2002Assignee: Rosemount Inc.Inventors: Steven M.

Patent number: 6484585Abstract: A pressure transmitter in a process control system for transmitting pressure on a process control loop includes a transmitter housing, an isolation diaphragm configured to couple to a process fluid, and a pressure sensor body of a brittle corrosion resistant material operably coupled to the housing and positioned in the housing. The pressure sensor comprising a first portion bonded to a second portion by a fusion bond, the fusion bond substantially free of foreign material. An isolation fluid is configured to fluidically couple the pressure sensor body to the isolation diaphragm to thereby couple the pressure sensor to a pressure of the process fluid. Measurement circuitry in the transmitter housing coupled to the pressure sensor provides an output which is a function of capacitance, a loop interface in the transmitter housing coupled to the measurement circuitry configured to transmit a pressure related signal on the process control loop as a function of the pressure.Type: GrantFiled: June 26, 2000Date of Patent: November 26, 2002Assignee: Rosemount Inc.Inventors: Fred C.

Patent number: 5372046Abstract: A vortex flow transmitter has a filtering circuit receiving a noise contaminated input signal representative of the flow and which has a fundamental frequency varying responsively to flow. The filter filters the input signal using one of a family of HP filter characteristics to produce a filtered signal having a frequency representative of the physical parameter. Each member of the family of HP filters has varying corner frequencies, each filter having a unique switchup and a unique switchdown value assigned to it. Adaptive response element select a current HP filter for use in the filter. Adaptive circuitry uses one selection method when the flow is increasing and another selection method when the flow decreases. Finally, output circuitry converts the signal from the filter into a transmitter output, typically a 4-20 mA current or a frequency output representative of the flow.Type: GrantFiled: September 30, 1992Date of Patent: December 13, 1994Assignee: Rosemount Inc.Inventors: Lowell Kleven, Roger Frick
