Publication number: 20240081994Abstract: A steerable delivery system is provided for delivering a replacement heart valve to a native heart valve location. The steerable delivery system includes an outer sheath assembly having a capsule along a distal end portion for retaining the replacement heart valve in a compressed configuration. The capsule is constructed to provide both compression resistance and flexibility. The capsule may be formed with an outer polymer layer, a metal middle layer located on a radially inner surface of the outer polymer layer, and an inner liner located on a radially inner surface of the metal middle layer. A fluoroelastomer layer is provided for bonding the inner liner to the metal middle layer. The metal middle layer is preferably a metal hypotube.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Alexander H. Cooper, David Robert Landon, Kevin M. Stewart, Garrett Dallas Johnson, Glen T. Rabito, Tarannum Ishaq Gutierrez, Hiroshi Okabe, Ramon Aguilar, JR., Jesse Robert Edwards, Taylor Jacob Scheinblum, Patrick Chow, Julio Cesar Sanchez, Hieu Minh Luong

Publication number: 20230199427Abstract: In some embodiments, virtualization methods for generating a binaural signal in response to channels of a multi-channel audio signal, which apply a binaural room impulse response (BRIR) to each channel including by using at least one feedback delay network (FDN) to apply a common late reverberation to a downmix of the channels. In some embodiments, input signal channels are processed in a first processing path to apply to each channel a direct response and early reflection portion of a single-channel BRIR for the channel, and the downmix of the channels is processed in a second processing path including at least one FDN which applies the common late reverberation. Typically, the common late reverberation emulates collective macro attributes of late reverberation portions of at least some of the single-channel BRIRs. Other aspects are headphone virtualizers configured to perform any embodiment of the method.Type: ApplicationFiled: February 13, 2023Publication date: June 22, 2023Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Kuan-Chieh YEN, Dirk Jeroen BREEBAART, Grant A.

Publication number: 20220317315Abstract: The system and method for position, navigation, and timing and more particularly to a system that is time and/or position independent and capable of autonomous transition from GPS to non-GPS navigation. The integrated position, navigation, and timing system uses primary and secondary navigation sensors and primary and secondary navigation measurement sources with a common time reference architecture, an integrated “dual-grid” navigation module, an integrated “dual-grid” navigation Kalman filter, and an integrated “dual-grid” navigation source selection module to provide both geodetic and relative grid timing and/or location among members of a network of platforms, particularly in GPS denied or degraded environments.Type: ApplicationFiled: April 5, 2021Publication date: October 6, 2022Applicant: BAE SYSTEMS Information and Electronic Systems Integration Inc.Inventors: David M.

Patent number: 10805035Abstract: A secure wireless transceiver, such as a link 16 transceiver, receives signals using an antenna array having an SOC associated with each antenna element in the array. The SOC's digitize and channelize received data for transmission to a message nulling system that mitigates jamming. The antenna array can be conformal, and can replace an existing Link 16 blade. The disclosed transceiver can be a modified CMN-4 transceiver with digitizing and channelizing moved to the SoC's, and replaced by the nulling system. The transceiver uses applicable TRANSEC information to assign received data to the logical Link 16 channels before nulling, and embodiments apply nulling only to channels of interest, thereby improving the nulling and reducing side lobes. Embodiments distinguish between desired and unwanted signals based on known Link 16 signal features and/or situational awareness, rather than signal amplitudes, thereby enabling nulling of even weak jamming signals.Type: GrantFiled: May 22, 2018Date of Patent: October 13, 2020Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: David M Cooper, John H Chongoushian

Patent number: 10782706Abstract: The present disclosure provides a spread spectrum landing system with a low probability of intercept altimeter that is in communication with a plurality of asymmetrically placed antennas or transponders near a landing area. The low probability of intercept altimeter acts as a secondary system in the event that a primary landing system for the mobile platform is denied or otherwise inoperable. The low probability of intercept altimeter cycles through unique pseudo noise (PN) codes to determine a line of sight relative to each antenna or transponder. A single algorithm or process determines and ranges the platform relative to the transponders to effectuate the landing of the platform.Type: GrantFiled: January 29, 2018Date of Patent: September 22, 2020Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: David M.

Patent number: 9420008Abstract: A system and method for repurposing of cryptographic capabilities in an electronic warfare (EW) environment is presented. A method begins by determining in a client system a cryptographic function to be performed; however, the client system does not have any cryptographic functionality. The client system then requests the cryptographic function be performed in a cryptographic logic that is physically secured with the client system and is external to the client system. The cryptographic logic performs the cryptographic function to produce a cryptographic result. The cryptographic result is then provided to the client system.Type: GrantFiled: March 13, 2013Date of Patent: August 16, 2016Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Sharon K.
