    Of course it is clear.

    BOTH!

    Growth would require capital expenditures.
    That would still be considered continuing operations.

    What would be bad is all this stock selling supports paying salaries and existing expenses with no new orders.
    Just to survive.

    We need to hear of new orders or see them in the Q report in the form of backlog.

  • If this is sold in one scoop, to a known entity, it would be a fantastic development.

    Sony, Intel, any other highly recognizable name, would make the PPS appreciate.

    This would be a serious public recognition of the technology.

    If it's a bunch of investors, from the latest conferences, than it might just be a need for cash for operations. Then we'll need to see some serious order coming in.

    Stay tuned for the roller coaster ride!

    Hillerby55 said that Sumitomo corresponded with him and indicated those modules would be available in pre-production starting in March.

    Not sure what volume is available as of today.

    May not be high volume commercial production available yet to the point that they would take open orders and display the module in catalogs.

    This information always reaches us way after the fact.

    Anything sold by the manufacturer has to be tested.

    There are rules regarding add-ons and stuff you hang to your mirror or stick on the dash, many of those rules by your insurance company.

    Mine would not cover injuries caused by a "flying" phone or laptop if it wasn't secured properly. I found out one of my business acquaintances did not get covered for his laptop hitting the windshield after he hit a post at the gym parking lot. The laptop was on the rear seat and went flying and cracked his windshield. Laptop and windshield needed replacement and the insurance denied any claim for them.

    It's in the fine print none of us ever read.

    AEC-Q100 Grades 0(-40C to +150C On Engine), 1(-40C to +125C Under The Hood) and 2(-40C to +105C ECU Box) are for outside the driver compartment and usually under the hood or inside engine components.

    AEC-Q100 Grade 3(-40C to +85C Driver Interior/Under Dash Board) is required for in dash and inside the "car":.

    The Sumitomo module is designed for the Grade 3 (-40C to +85C) temperature range.

    In their paper, they indicated that their DIP module is appropriate for HUDs (Located In Or Under Dash).

    That is an available component.

    Nothing is obvious and we do not know the details of the Sony agreement. Neither do you. From waht we know, Sony only buys the mirror and the mirror driver software from MVIS.

    Automotive grade components are a different animal that household pico projectors.

    Intersil claims this is the industry only automotive grade driver for MEMS scanned laser HUD.

    Class 3R

    You are mixing two topics that are not related.

    Dr. Buckley described the limitations of MVIS engine in Class 2 taking in account pulsed laser projection technology.

    The safety classification and it's application by various countries in determining the limits of what they allow for consumer class products is not related Dr. Buckley's paper but to IEC methodology and information.

    Stop mixing the topics.

    Class 3R

    pierrev55 pierrev55 Jun 17, 2016 11:42 AM Flag

    Obviously you never read Dr. Buckley's paper.

    He calculated that the maximum brightness, in Class 2, for an MVIS sinusoidal LBS engine, would be around 15 lumen. He never published that 15 lumen was the limit for LBS. MVIS was going to use the new Corning 80 mW SHGL and produce a Class 2 20 lumen engine. That Corning SHGL never saw the light of day.

    When Microvision introduced the Gen2 PicoP, it was at 25 lumen and Class 3R. Used DGLs.

    Class 2 is currently the limit in the EU and some other countries for consumer class products.

    Proximity detection could be used to lower thew brightness to Class 2 when in the 10-40cm range. Dr Buckley produced another paper showing that MVIS LBS engine could double brightness at around 40cm and still be in Class 2 at that distance and be adjusted by decreasing the brightness as you get close to the 10 cm. The point was that proximity detection would work for MVIS LBS engine.

    The technical hurdle for LBS would be how much laser light (mW) the mirror can absorb before showing mechanical artifacts caused by heat. If the mirror is too big then it can't really be small or fast enough.

    Obviously your understanding of sinusoidal LBS technology is very limited.

    Give credit to KG for his technological expertise.

    However his engineer background creates a bias versus any technology that is not perfect.

    The marketing people see an opportunity for such technology because humans are not machines and they like technology that provides them pleasant stimuli regardless of the technology imperfection.

    It's not at 40%.

    It's at 3.4 out of 5.

    You are correct, a lot of the negative 1 start reviews are from non verified purchasers or people who obviously do not even have the projector.

    The latest one where he claims the unit displays an 18" picture at 3 feet and displays an ultra wide image obviously does not have one.

    A lot of those negative reviews are for impossible issues.

    There are many 5 start reviews that seem suspicious too.

    Too many 1 start reviews are stuff like "It's junk" or "does not work". No actual review.

    Hey sensibull1,

    KG is actually bringing interesting questions that need to be addressed.

    Instead of calling him names, you should probably do a little DD.

    I will refer to Dr. Buckley's paper where he demonstrated that increasing the vertical resolution increases brightness.

    The limitation of the Class was due to the pulse train limitation and not the mW sent to the entire aperture where the classification is calculated. The aperture could handle more mW than LBS produced.

    Vertical resolution doesn't change the pulse train. It only affects the entire mW produced in the aperture.

    What you are saying is that if the engine produced 1 pixel, it would have the same brightness as if it produced an infinite number of pixels of the same duration, in the same area, in the same amount of time?

    The illumination source is the same but it produces more pixels of the same power, in the same amount of time, in the same area. Having more mW reflected, in the same amount of time, from the same area obviously increases brightness perceived by you eyes.

    Your thinking works for panel based engines because you split the same illumination by a higher number of pixels

    I will defer to Dr Buckley calculations and paper.

    More pixels produced in the same area = higher brightness. The horizontal pulse train is the limiting factor in the LBS brightness engine using sinusoidal imaging.

    This was demonstrated and calculated in Dr. Buckley's paper on safety of LBS systems.

    Using the MVIS engine an example, staying in class 2, brightness could be increased by modifying the vertical resolution, as shown in Figure 5 of the paper:

    480p: 11 lumens
    720p: 15.2 lumens
    1080p: 21 lumens

    "To achieve a Class 1 classification, the D65 white balanced
    luminous flux emitted by a WVGA single-mirror
    scanned beam system is limited to approximately 1 lm, while
    the corresponding Class 2 limitation is roughly 11 lm."

    "Brightness can also be increased by increasing the
    number of vertical lines, as per Eq. (18); as Fig. 5 demonstrates,
    in which the maximum Class 2 brightness is evaluated
    at resolutions of similar aspect ratio, a 720p system
    could emit a maximum of 15.2 lm while remaining a Class 2
    system."

    PicoBit was submitted for certification.

    We can safely assume the engine is ready.

    I, too, hope AirPlay is included. That would be a game changer. But I do not count on it too much. Apple has been resisting to license its video streaming feature.

    Auto keystone correction and a brighter engine would be great.

    Higher resolution is not really expected at this time. The only benefit of increasing the vertical resolution would be to get higher lumens and a subjective increase in image quality. This would require a new mirror and new software.

    Maybe the Sumitomo module is integrated in a smaller engine and produces a better pixel.

    We will see.

    Definitely higher lumens and auto keystone correction would be welcome.

  • DLP has a better image quality than LBS at the same resolution, in the presentation of fine details like very small text or very fine graphics.

    In the case of mobile or ad hoc presentations of various "non specialized screens" there is no significant difference. Projecting a movie on a tent side or an office wall is not going to display much difference.

    However this is not really a practical solution for small embedded format, if that format becomes widespread.

    The current TI 1080p chip is the DLP4710:
    Cost: $180/1K.
    Size: .47in diagonal. (The needed lens makes this a very thick projection engine).

    Need the following additional chips ($30/1K) to make a complete chipset:
    DLPC3439
    DLPA3000/DLPA3005:

    The cost is already $210/1K.

    LBS can scale way better than DLP while staying at the same small size.

    Hopefully the Sumitomo module will bring a smaller engine.

    1080p will require MVIS to introduce a different mirror with a higher resonant frequency.
