Patent number: 9036751Abstract: A receiver applies a calibration method to compensate for skew between input channels. The receiver skew is estimated by observing the coefficients of an adaptive equalizer which adjusts the coefficients based on time-varying properties of the multi-channel input signal. The receiver skew is compensated by programming the phase of the sampling clocks for the different channels. Furthermore, during real-time operation of the receiver, channel diagnostics is performed to automatically estimate differential group delay and/or other channel characteristics based on the equalizer coefficients using a frequency averaging or polarization averaging approach. Framer information can furthermore be utilized to estimate differential group delay that is an integer multiple of the symbol rate. Additionally, a DSP reset may be performed when substantial signal degradation is detected based on the channel diagnostics information.Type: GrantFiled: January 17, 2013Date of Patent: May 19, 2015Assignee: ClariPhy Communications, Inc.Inventors: Shih Cheng Wang, Martin Serra, Cesar Sanchez Peñak, Mario Rafael Hueda, Alfredo Taddei, Diego Ernesto Crivelli, Hugo Santiago Carrer, Oscar Ernesto Agazzi

Patent number: 8513581Abstract: A multi-caliber fuze kit includes a fuze housing configured for coupling with multiple projectiles. One or more canards are moveably coupled with the fuze housing. The one or more canards are adjustable between two or more canard configurations. In a first canard configuration, the one or more canards are at a first canard angle relative to a bore sight of the fuze housing, and the first canard angle is configured for use with a first projectile. In a second canard configuration, the one or more canards are at a second canard angle relative to the bore sight of the fuze housing, and the second canard angle is configured for use with a second projectile.

Patent number: 8203108Abstract: A fuze guidance system is configurable by an end user, allowing the end user to select between different configurations of canards of the system. The different configurations of canards may include canards with different surface areas, optimized for providing appropriate control with different sizes of munitions. The different configurations may be accomplished by having canards with separable portions which may be broken off or otherwise removed by the end user, to reduce canard surface area and/or span. Alternatively the fuze guidance system may come in a kit with multiple sets of canards having different sizes or otherwise having different configurations for providing different aerodynamic characteristics. The end user may select a canard set based on the munition size or type that the fuze guidance system is to be used with.Type: GrantFiled: August 8, 2008Date of Patent: June 19, 2012Assignee: Raytheon CompanyInventors: Chris E.

Patent number: 7849797Abstract: A projectile fuze sends a signal having encoded telemetry data. The telemetry data may be encoded by modulating an aspect or characteristic of the signal, such as frequency modulation of the signal. The fuze may receive and interpret reflections in order to determine proximity to a target or other object, such as by functioning as a height of burst sensor. The signal may include a series of random or seemingly random pulses (a keyed pattern of pulses), such as pulses in amplitude of the signal. The fuze includes a pair of transceivers for sending signals of different frequencies through an antenna, and for receiving signals through the antenna. The transceivers are configured such that one or the other is used at any one time when telemetry data is sent, with telemetry being encoded by changes in frequencies.Type: GrantFiled: October 31, 2008Date of Patent: December 14, 2010Assignee: Raytheon CompanyInventors: Chris E.

Patent number: 7819061Abstract: A smart fuze system includes a radome used to hold a replaceable smart fuze module in place. An internally-threaded collar screws onto threads on the main body of the smart fuze system. Pressure from the radome presses the smart fuze module against electrical connections in the main body. The smart fuze module may thereby be held in place without potting material, allowing different types of fuzes to be swapped into place. The different types of fuzes may include a type that communicates height of burst (HOB) information a type that communicates telemetry, and a type that communicates both HOB and telemetry information.Type: GrantFiled: September 8, 2008Date of Patent: October 26, 2010Assignee: Raytheon CompanyInventors: Chris E.
