OLD news perhaps now but wondering if it also applies to HMDS II 'fixes'? Anyhoo...

Kopin Delivers World’s Highest-Resolution Microdisplay To Vision Systems International (VSI) 12/12/2011

http://ir.kopin.com/Investors/Press-Rel ... fault.aspx

"2K x 2K AMLCD is Targeted for Next-Generation Night Vision Systems

TAUNTON, Mass.--(BUSINESS WIRE)-- Kopin® Corporation (NASDAQ: KOPN) today announced the delivery of the world’s highest resolution micro-display to Vision Systems International, LLC (VSI) of San Jose, California. The display, which exceeds High Definition (HD) resolution, was developed by Kopin under funding provided by VSI and the U.S. Government. This ultra-high resolution display boasting a resolution of 2,048 x 2,048 is specifically targeted for the next-generation night vision systems for the U.S. Department of Defense (DoD).

“Kopin has a solid history in the development of microdisplays for an array of U.S. Army thermal imaging programs and has proven to be a valuable partner in our development of advanced night vision systems for avionics,” stated Drew Brugal, President of VSI. “This new high-resolution display was developed and delivered on-time to address the aggressive imaging system requirements of advanced night vision Helmet Mounted Display (HMD) systems. This partnership places VSI on the forefront of next-generation night vision HMD systems that will replace the traditional image intensifier implementations with an all-solid-state, ejection-safe solution for our aviation community,” continued Brugal.

“Kopin is once again expanding the boundaries of micro-display resolution and performance by developing an active matrix liquid crystal display (AMLCD) with a 2048 x 2048 monochrome pixel resolution in a 0.96-inch diagonal form factor,” said Kopin President and Chief Executive Officer Dr. John C. C. Fan. “This new display reflects the strategic research and development initiatives we have undertaken over many years, efforts that have resulted in innovations including low-voltage and clock driverless architecture, small pixel geometry, and specialized and ruggedized LCD processes. The new 8-inch processing line Kopin developed in partnership with the U.S. Government was critical in the design and fabrication of such a high-resolution display.”

“This new display will provide users with night vision resolution which rivals the current image intensifier tube,” stated Michael Presz, Kopin’s Vice President of Government Programs and Special Projects. “Targeted for use with the Intevac ISE4000 sensor, this device will allow for target detection at extreme ranges and the ability to detect hazards such as power lines and towers, thus improving mission effectiveness and reliability. In addition, the AMLCD display solution allows for the HMD system designers to integrate the night vision imagery into the avionics and weapon system suites, an extremely powerful capability which is not possible with direct-view image intensifiers.”

INTRODUCTION TO HELMET-MOUNTED DISPLAYS

http://www.usaarl.army.mil/publications ... splays.pdf (5.8Mb)

"...Helmet Mounted Display System (HMDS) (United States)
The Helmet Mounted Display System (HMDS) (Figure 3-20) [original HMDS] is being developed for the F-35 Joint Strike Fighter (JSF) by VSI. It has completed all required safety of flight tests, allowing in-flight seat ejections up to 450 KEAS (knots equivalent air speed). It has demonstrated structural integrity to 600 KEAS as a critical risk mitigation step towards full flight certification. The HMDS had its maiden flight on 4/10/2007 on the 10th test flight of the F-35 JSF.

The HMDS provides the pilot video with imagery in day or night conditions combined with precision symbology to give the pilot enhanced situation awareness and tactical capability. For tactical fighter jet aircraft, the F-35 JSF will be the first to fly without a dedicated HUD, with the HMDS providing this functionality. The HMDS uses the same symbology implemented in the JHMCS. The CRT display in the JHMCS has been replaced by two 0.7-inch diagonal SXGA resolution AMLCDs. The HMDS provides a FOV of 40° (H) x 30° (V)."

Someone commented 'why is the HMDS II not used in the F-35 Simulator?' Here perhaps is a part answer....

Improving the Utility of a Binocular HMD in a Faceted Flight Simulator

http://www.saphotonics.com/wp-content/u ... -Final.pdf (0.4Mb)

"ABSTRACT
Faceted simulator displays are widely used because they are relatively compact and economical. One drawback, however, is that viewing distance changes depending on where users are looking. This variation creates a challenge for the integration of binocular head mounted displays (HMDs), because confusing imagery and visual fatigue can result when the user views symbology presented by the HMD at one distance and simulator imagery at different distances. Understanding the best approach to presenting symbology with a binocular HMD in a faceted simulator has become an important issue, with the deployment of the F-35 Joint Strike Fighter and its binocular HMD. Successful integration of a binocular HMD would not only allow current faceted simulators to be retrofit with the F-35 simulator HMD, but would also allow future simulators to have either a dome or faceted design, thus affording acquisition agencies greater flexibility. Binocular HMDs are becoming more prevalent, so solving this integration issue will likely become important for multiple platforms.

We performed an experiment to quantify the best method of presenting symbology on a binocular HMD when used with a faceted simulator display. Five viewing conditions were tested: 1) HMD converged to 36”, 2) HMD converged to 42”, 3) dynamic HMD vergence, 4) monocular presentation on the HMD, and 5) on-screen presentation. Screen distances ranging from 36” to 54” were tested.

Our results suggest that adaptive vergence is the preferred solution. Both static vergence conditions and the monocular condition resulted in lower comfort scores and poorer performance. The on-screen condition, although rated comfortable, does not represent the real-world flight condition where symbology is displayed using an HMD. Although additional evaluations under more operational conditions remain to be completed, these results indicate that adaptive vergence is a viable solution for the integration of binocular HMDs into faceted flight simulator displays."

...Discussion
...In summary, we believe that adaptive vergence provides a viable solution for integrating a binocular HMD with faceted display systems. This recommendation is supported not only by viewing comfort data, but also by user performance data. We believe these results apply not only to the M2DART, but also to other faceted simulator displays with similar viewing distance ranges.

We will seek to confirm our conclusions by integrating the F-35 simulator HMD with dynamic vergence control into a state-of-the-art faceted display system with pilots executing realistic training tasks under more operational conditions.

Development of an adaptive vergence control system would provide existing users of faceted display systems with a solution for integrating binocular HMDs for future training applications, and provide acquisition agencies with additional alternatives when evaluating competing display system designs for training systems requiring binocular HMDs in simulators."

And I missed the memo about the 'StrikeEye' being another version of HMDS but guessed it - here is confirmation...

StrikeEye and F-35 HMDS Product Update

http://www.vsi-hmcs.com/index.php/blog/ ... uct-update

“You may have seen in the news this past Wednesday (8/31) [2011?] that two F-35As, an AF-10 and AF-11, & two F-16 chase aircraft are poised for take-off at Eglin AFB, & that the F-35 JPO authorized a return to flight operations for F-35 production aircraft, all equipped with HMDS.

Our StrikeEye HMDS product is effectively the equivalent to the F-35 HMDS product. As the F-35 avionic architecture is unique, we created the StrikeEye product line to address other potential platforms requiring a Wide Field of View (WFOV) binocular HMD. And I just want to mention our StrikeEye HMDS recently completed highly successful testing of the next-generation night vision camera.

Though the technology of our next-generation night vision camera is revolutionary, we at VSI are committed to making it better, faster & more cost effective. As we continue to invest in the technology, we’re confid-ent that we are on the right path to achieving night-vision capabilities previously unavailable to fighter pilots. The bottom line: our combat-proven HMDS are the “low risk” solution for fixed-wing tactical aircraft.”

“Just do it”: A test pilot speaks By Colonel (Retired) Jim Sandberg May 6, 2012

http://www.sldforum.com/2012/05/%E2%80% ... ot-speaks/

“Helmet-Up” the Harriers, Now! - Published in USNI Proceedings, November 2009 By Colonel Jim Sandberg, U.S. Marine Corps Reserve (Retired)

"By 20[ZZ]—in less than [YY] years—the Marine Corps will have completed sufficient individual and organizational training and received enough aircraft to declare an initial operating capability with their first operational squadron of F-35Bs, the unique short-takeoff/vertical landing variant of the long-awaited Joint Strike Fighter....

...Accelerating and Unifying Operations
With the introduction of the F-35B, the Corps continues to merge its TACAIR capabilities and cultures from the Harrier, Prowler, and Hornet communities into a more cohesive supporting force for Marines and joint and coalition forces. AV-8B pilots and their Harrier squadrons, with their short-takeoff/vertical landing expertise and VMA culture and TTPs, will be joined by EA-6B and F/A-18 pilots and their own VMAQ and VMFA experiences.

I wonder if the Harrier and Prowler warfighters will marvel at the magic of the Lightening(sic) II’s HMD as their primary flight and combat display. I wonder if the HMD-experienced Hornet drivers will say something like, “Hey, neat helmet! I wonder if I can do [fill in the blank] with it.”

Colonel Art Tomassetti, USMC, Vice Commander of the 33rd FW, Eglin Air Force Base, sums up the situation:

All F-35 students walk to the airplane for the first time by themselves, without an instructor in their plane. We should strive to reduce the number of times that a pilot says ‘this is the first time I’ve done this or used this’ with actual flight hardware to the max extent possible. Side stick, HMD, touchscreens, Distributed Aperture System, voice activation, Fly-By-Wire, and so on, some of these we can do well in the simulators and some we can’t. The only other thing these pilots bring is their aviation experience. If that experience includes some of these F-35 capabilities, great. If not, well. . .

Colonel Sandberg flew A-4 Skyhawks in the early 1970s. Graduating from USAFTPS in 1977, he served as operational test pilot in VX-4, Point Mugu, California, flying the A-4, F-4, F-14, and new F-18. He was the 31st pilot to ever fly a Hornet. After leaving active duty in 1982, he worked for Northrop as an engineering test pilot and finally as Director of the F-35 Integrated Test Team at Pax River. A former president of the Society of Experimental Test Pilots, he now works as an independent consultant. One of his clients is GENTEX Corporation, an HMD developer.

There was a question about 'voice recognition' in F-35 with this company supplying it. More to follow...

U.S. Air Force - Test Pilot School | Test Pilot School Avionics Familiarization Simulator

http://www.zedasoft.com/solutions/tps.jsp

"...An Adacel eSRS voice recognition system is integrated and used to demonstrate advanced voice command interfaces like the one being proposed for the F-35 Lightning II fighter....

...Helmet-Mounted Display Upgrade to USAF Test Pilot School’s Avionics Familiarization Simulator

In May 2010 ZedaSoft delivered a Helmet Mounted Display (HMD) upgrade to USAF Test Pilot School PSD. The HMD upgrade used an NVIS nVisorST see-through helmet-mounted display design with a 40 degree vertical field-of-view that simulates the field-of-view of monocular J/HMCS designs as well as the binocular design used in the Joint Strike Fighter cockpit. ZedaSoft integrated this HMD with the original InterSense IS-900 head tracker system. The HMD symbology was modified so it could be rendered either directly in the IG or in the HMD. When rendered in the HMD the symbology can be optionally combined with simulated NVG imagery generated by one of the MetaVR VRSG channels."
________

Speech Recognition – The Adacel Difference

http://www.adacel.com/solutions_service ... erence.pdf (200Kb)

"...Flexible Speech Recognition: Adacel’s unique software architecture allows its systems to identify and analyze commands regardless of the speed or pattern of speech. As a result, users do not need to artificially modify their method of speaking to suit the software. The Company’s simulation and training systems are capable of identifying commands even if the speaker stutters, hesitates or corrects himself in the middle of a command. The result is a system that allows students to focus on key objectives without unnecessary distraction.

No Accent Bias: Because of the Company’s unique approach to developing its speech recognition software, Adacel’s simulation tools function regardless of the operator’s accent. This capability allows Adacel to market its systems to a wide range of customers without significant modifications or customization...."

Another take on fitting the HMDS with added info: [see also previous page on this thread]

State of the art technology supports F-35 pilots June 15, 2012 JUSTIN HEINZE / Daily News

http://www.nwfdailynews.com/articles/pi ... ports.html

"...A little later, Dorn climbed into a metal frame-supported harness of the parachute descent trainer, which allows pilots to practice post-ejection safety. Wearing a virtual reality helmet which simulated an actual ejection, Dorn’s goal was to navigate his parachute to the ground.

“We run through scenarios where we create different malfunctions, Air Force Master Sgt. Shawn King said. “His ropes will be mixed up or something will be wrong.”

Dorn’s progress in his virtual environment was displayed on a large TV screen mounted on the wall.

The room also contained a hypoxia flight simulator, a system obtained by aerospace physiologist Air Force Capt. Ryan Seymour. In the past, oxygen-depletion training was done in chambers where pilots would be asked simply to complete math problems or crossword puzzles to test their mental capacity under hypoxia-like duress, Seymour said.

Seymour’s simulator allows pilots to perform in-flight tasks while under the influence of hypoxic symptoms, which can include color-blindness, hot and cold flashes, tingling sensations and altered consciousness....

...Perhaps even further behind the scenes, King said explained how the F-35 flight suits expanded on previous models’ protection from gravity forces.

“This is a full coverage suit
,” King said. “It allows them to sustain higher G’s for longer. It basically forces blood to stay in the right place in the body.”..."

Lockheed’s comprehensive Q&A on the F-35 By Philip Ewing, June 19th, 2012

http://www.dodbuzz.com/2012/06/19/lockh ... -the-f-35/

"...Q: Sounds pretty high speed, but isn’t the helmet the pilot needs to use all this jacked up?

A: Lockheed wouldn’t use that term – O’Bryan said the company believes it can make its original pilot helmet work as promised. He detailed the three major problems it has faced: “Latency” — a lag between what DAS sees and what it shows the pilot; “jitter” — the effect a jet’s natural shaking has on the image the pilot sees; and “night acuity” – how sensitive an F-35’s sensors are in total darkness.

O’Bryan said Lockheed believes new software – ah yes, software; we’ll get to that in a moment – can eliminate the latency problem. As of now the lag between what DAS sees and what a pilot sees is “measured in milliseconds.” Engineers think they can solve “jitter” by incorporating “inertial stabilization units,” like the ones you might find in a digital camera lens. And a new camera will enable Lockheed to improve an F-35’s night acuity, to the point where you can land a B on an amphib at midnight, in the middle of the ocean, with no lights.

In the meantime, as you read here last week, the program is also pursuing a second, less wham-o-dyne helmet in case the first one doesn’t materialize as promised. But could it take advantage of the cameras and sensors built into the F-35? O’Bryan said he didn’t know. The original helmet has flown “successfully” more than 2,000 times, he said, and Lockheed believes it can bring it into spec.

Meanwhile, the GAO report said it’s costing $80 million to both improve the original helmet and pursue a second one in parallel...."

Dual path development maintained for F-35 helmet 28 June 2012
"Lockheed Martin will continue with its dual path development for the F-35 Lightning II's helmet, despite the company's confidence in the system under development by Vision Systems International (VSI). VSI - a collaboration between Elbit Systems and Rockwell Collins - is the incumbent manufacturer of the F-35's helmet-mounted display system (HMDS); however, a number of issues have arisen with the unit and in March 2011 Lockheed Martin announced a competition to purchase a helmet made with commercial off-the-shelf night-vision goggles (NVGs) and components."

Lockheed Martin Reports Progress on F-35 Helmet Display 06 July 2012 by Bill Carey

http://ainonline.com/aviation-news/2012 ... et-display

"A Lockheed Martin executive reported “lots of progress” in fixing problems associated with the F-35 Joint Strike Fighter helmet-mounted display system (HMDS). But the company continues developing an alternate helmet display in case the existing system fails to meet requirements. Critical design reviews of both systems are planned in the fourth quarter.

In a briefing in mid-June, Steve O’Bryan, Lockheed Martin vice president for F-35 program integration and business development, described progress with three fixes aimed at mitigating night-vision, latency and jitter problems with the Gen II HMDS supplied by Vision Systems International (VSI), a joint venture of Elbit Systems of America and Rockwell Collins. Those problems identified by pilots led Lockheed Martin to award a contract to BAE Systems last September to develop an alternate HMDS with detachable night-vision goggles.

To improve night-vision acuity, an upgraded ISIE 11 electron-bombarded active pixel sensor from Intevac, of Santa Clara, Calif., will be mounted on the helmet and in the nose of the aircraft. The higher-resolution sensor will be tested this summer at MIT Lincoln Laboratory, O’Bryan said. Latency in acquiring imagery from the F-35’s distributed aperture system, quantified in milliseconds and described as “excessive” in a 2011 review by the Department of Defense (DoD), can be improved with “software tweaks,” according to O’Bryan. “We believe latency is very much on track,” he said. The issue of helmet display jitter, which the DoD said makes flight symbology difficult to read and is “tactically significant” for engaging weapons, will be addressed by incorporating micro inertial measurement units (IMUs) to stabilize the image. IMUs have been installed in the laboratory and will be tested in flight this summer, O’Bryan said.

BAE Systems, which has not yet flown on the F-35. “Until we are sure that we can meet the needs of the warfighter, we’re going to have a ‘dual-path development’ with the alternate display,” O’Bryan said...."

A bit more about the esoteric world of the F-35 Flight Safety/Survival Equipment....

Diverse And Growing Cobham Quietly Contributes To Major Aircraft Programs by Bill Carey July 10, 2012

http://ainonline.com/aviation-news/2012 ... t-programs

"...In the military arena, Cobham supplies 100 components and $1 million worth of content on the Lockheed Martin F-35 Joint Strike Fighter. These include the fifth-generation fighter’s refueling probe, the cryocooler used to cool the infrared detector of its electro-optical targeting system, the pneumatic bomb racks, integrated microwave assemblies supporting electronic warfare systems in the tail and the cartridge actuated cutter, which automatically cuts an air passage in the pilot’s oxygen mask hose when the pilot resurfaces after being submerged in water...."

Nothing else relevant to F-35 at the jump. :-(
