Publication number: 20170212027Abstract: The invention relates to a system and a process for analyzing the interaction between a drop of fluid which is immiscible in an ambient medium and a surface, this surface being another drop of fluid or else alternatively a solid surface. The system also comprises processing means suitable for determining, according to data collected by an image acquisition and processing device, a value of interfacial tension of the drop after a contact between the drop and the surface, and a value of pressure difference between the internal pressure of the drop and the pressure in the ambient medium without having to know the position of the apex of the drop. The invention also relates to a device for forming drops and bringing drops into contact and to a device for forming a drop of fluid and bringing a drop of fluid into contact with a solid surface for the purpose of analyzing them by means of the appropriate system.Type: ApplicationFiled: January 3, 2017Publication date: July 27, 2017Applicant: TECLISInventors: Alain CAGNA, GĂ©rard ESPOSITO

Patent number: 9255595Abstract: Techniques and architecture are disclosed for implementing an optical dome bezel to interface an optical dome/window and a housing of differing coefficients of thermal expansion (CTEs), In some embodiments, the bezel may comprise a material (e.g., Ti-6Al-4V) that is CTE-matched to the optical dome material (e.g., silicon, germanium, sapphire, ALON), thereby mitigating temperature effects on system performance. In some embodiments, the bezel may include a radially compliant flexure feature (e.g., flexure blades, spring-form S-channels), which mitigates physical stress effects (e.g., vibration, thermal expansion/contraction, etc.) on system performance. In some embodiments, the bezel may include an integral environmental sealing feature (e.g., O-ring gaskets), which protects internal optics/electronics from external environmental hazards (e.g., moisture, corrosive substances, particulates, debris).Type: GrantFiled: April 16, 2012Date of Patent: February 9, 2016Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Glenn Sindledecker, Gerard A.

Patent number: 9214408Abstract: A fluid cooled thermal management technique for a high-density composite focal plane array (CPFA) is disclosed. In one embodiment, a high density CFPA assembly includes a plurality of imaging dies mounted on a front surface of a printed wiring board (PWB) and a base plate. The base plate has a substantially matched coefficient of thermal expansion (CTE) to that of the high density CFPA. Further, the high density CFPA is disposed on a front side of the base plate. Furthermore, the base plate has a plurality of integral serpentine fluid flow channels configured to receive and circulate fluid and further configured such that the heat generated by the CFPA is transferred via conduction into the base plate and to the integral serpentine fluid flow channels and to the circulating fluid to dissipate the generated heat.Type: GrantFiled: September 5, 2012Date of Patent: December 15, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Gerard A.

Patent number: 9146369Abstract: A cross axis cable management system comprising a bird cage mechanism, a clock spring mechanism and a rolling loop mechanism positioned about a first axis, second axis and third axis of a gimbal mechanism respectively. Each mechanism provides defined channels and protective elements to prevent cable damage. The mechanisms also have one fixed end, one rotational end, and an optimized amount of slack for repeatable cable motion. The system effectively manages a large number of conventional and fiber optic cables while minimizing the friction or drag associated with the motion about the multiple axes and preventing cable damage and the resultant loss of performance.Type: GrantFiled: September 7, 2012Date of Patent: September 29, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Edward M. Kolvek, Dennis P. Bowler, Barry Lavoie, Gerard A. Esposito

Patent number: 8982270Abstract: A deformable focal plane array (DFPA) for imaging systems is disclosed. In one embodiment, the DFPA includes a detection circuitry on one side. For example, the thickness of the DFPA is in a range of about 5 to 40 microns. In one exemplary embodiment, the DFPA when warped to a desired shape provides a substantially wider field of view (FOV) than a flat focal plane array (FPA).Type: GrantFiled: September 6, 2012Date of Patent: March 17, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Dennis P.

Patent number: 6922518Abstract: Methods and apparatus for hermetically sealing an optical fiber in a feedthrough connection. In brief overview, the optical fiber is mounted in a housing whose physical properties differ from that of the fiber by utilizing a structure in accordance with the present invention. The structure, typically in transition bushing form, is formed from at least two materials, such that the physical properties of a first material are selected to match the physical properties of the optical fiber, and the physical properties of a second material are selected to match physical properties of the housing. When the matched physical properties are the coefficients of thermal expansion (CTE) of the fiber and the housing, the result is a fiber optic mounting that remains hermetically sealed despite changes in ambient temperature that would typically induce stresses in the seal, potentially causing its failure.Type: GrantFiled: October 21, 2003Date of Patent: July 26, 2005Assignee: Lighthouse Capital PartnersInventor: Gerard A.
