10/3/2007 | The Cobra HMD is a key element of Gripen’s advanced systems fit and has already been ordered by the South African Air Force. The agreement will enable the HMD system to be integrated into Swedish Air Force Gripen fighters and be delivered to Sweden progressively.
“This order is further evidence of the confidence Sweden has in Gripen,” says Lennart Sindahl, Business Unit Manager at Saab Aerosystems. “HMD further improves the Swedish Gripen fleet’s already expansive operating capacity.”
The HMD displays data directly onto the helmet visor, allowing the Gripen pilot to stay ‘heads-up’ at crucial points in the mission. The Cobra is a binocular system that displays both air-to-air and air-to-ground weapons symbology, as well as basic flight data.

and how do you know ANYTHING about the F35`s helmet since NOTHING has been made even remotely public....
The F-35 cockpit is also the first in a production fighter to use a virtual head-up display that projects information onto the pilot's helmet visor. The new system, called a helmet-mounted display, or HMD, was switched on in March for the first time in F-35 laboratories where it projected symbology onto the visor by way of the actual F-35 vehicle-management and display-management computers. The HMD provides HUD information as though pilots are looking through an actual HUD no matter in what direction they turn their heads.
"We have flown in the past with helmet-mounted sights, such as Joint Helmet-Mounted Cueing System, or JHMCS," explains Beesley. "This system is used for off-axis symbology for tactical maneuvering. But because of higher latency, or lag times, these systems cannot be used to fly the airplane. This latency issue has been solved thanks to improvements in computer technology that allow very quick update rates needed for information associated with flying the airplane."
With the virtual HUD, pilots can look in different directions to find key tactical and flight information in their line of sight. This off-axis capability, as it is called, increases lethality and survivability by allowing the pilot to target threats with head instead of aircraft motions. The HMD eliminates the cost and weight associated with traditional head-up displays and simplifies cockpit design.
"HMD advancements will improve both weapons' aiming and target information that flows to the pilot," Beesley says. "In the past, forward-looking infrared, or FLIR, imagery used for targeting was restricted to the narrow field of view of the head-up display or to the restrictions of a head-down display. With HMD, pilots can view the FLIR imagery in its true location, thereby greatly enhancing their awareness of the immediate environment."
In addition to these advancements, the HMD allows night vision display capability both on-axis and off-axis using the F-35's 360-degree array of infrared sensors, which is called a distributed aperture system. The sensors work in combination with night-camera technology.

VSI is now under contract to develop the Helmet Mounted Display System (HMDS) for the F-35 Joint Strike Fighter aircraft. Some of the features that will be provided by this next generation helmet system include:
Binocular Wide Field-of-View
Integrated day/night capability with sensor fusion
Highly accurate head tracking hardware and software
Digital image source for helmet vision displayed symbology
Custom helmet shell, liner and suspension system for lightest weight, optimal C.G. and maximum pilot comfort.

The F-35 is also fitted with additional sensor systems, including a an "infrared search and track (IRST)" system for defense and air-to-air combat, and a targeting system for precision attack on ground targets.
The IRST system is known as the "distributed aperture infrared system (DAIRS or DAS)". DAS includes six IR sensors mounted on different points of the fuselage to provide full-sphere IR detection and tracking. DAS can identify and pinpoint both incoming missiles and airborne targets.
Targeting is performed by the "electro-optical targeting system (EOTS)", featuring a forward-looking infrared (FLIR) imager; a CCD TV camera; a targeting laser; and a laser spot tracker. Unlike typical contemporary targeting systems, EOTS is not turret-mounted. It has a wide aperture that is blended into the aircraft's nose contours, covered by a window that is opaque to radar, and remains operational through the entire mission. It is derived from technology developed for the Lockheed Martin "Sniper" targeting pod.

This is Helmet Mounted Display - it projects the data from the HUD onto the screen...

How so...?
The helmet and display system have been developed by BAE Systems, the mask by G4, the helmet tracking system by Denel Optronics of South Africa, and the display symbology by Saab.

Except for the integration of Saab symbology (software) used on the Gripen into the display system I do not see anything national there. And as I have pointed out this particular display system is not exactly new or revolutionary, in terms of technology.

And maybe if he presses another button he can watch live EURO 08 qualifying matches.

What is the survivability of the F-35 cockpit if core electronic,avionics node/relay(s) are rendered inoperable?

Difficult to say, of course there is major redundancy, isolation etc… built into the system, even a back up power source independent of the main engine.
And as a Raptor driver once said, the FBW system on the F-22 is designed to never fail

Still, something like this is not likely to fail on it's own, at all, in 30 years of military FBW technology there has never been a single case that I am aware of where that system has failed in flight without an external stimulus.

Directed EMP weapon at a flight of FBW aircraft *might* result in system failure.

…does the F-35 have any non-digital instruments that will function in the event of a main generator failure or something?

I think we can all safely say that it'd be odd if the FBW system on the F-22 was designed to fail at regular intervals…
