I think the seller was Warren Buffett. Looks like he sold out 85%, must've seen a red flag.
No idea where he directed his money though, most of other semiconductor sector held well.

Why you will be seeing much more from event cameras
14 February 2023
February/March 2023
Advances in sensors that capture images like real eyes, plus in the software and hardware to process them, are bringing a paradigm shift in imaging, finds Andrei Mihai
The field of neuromorphic vision, where electronic cameras mimic the biological eye, has been around for some 30 years. Neuromorphic cameras (also called event cameras) mimic the function of the retina, the part of the eye that contains light-sensitive cells. This is a fundamental change from conventional cameras – and why applications for event cameras for industry and research are also different.
Conventional cameras are built for capturing images and visually reproducing them. They take a picture at certain amounts of time, capturing the field of vision and snapping frames at predefined intervals, regardless of how the image is changing. These frame-based cameras work excellently for their purpose, but they are not optimised for sensing or machine vision. They capture a great deal of information but, from a sensing perspective, much of that information is useless, because it is not changing.
Event cameras suppress this redundancy and have fundamental benefits in terms of efficiency, speed, and dynamic range. Event-based vision sensors can achieve better speed versus power consumption trade-off by up to three orders of magnitude. By relying on a different way of acquiring information compared with a conventional camera, they also address applications in the field of machine vision and AI.
Event camera systems can quickly and efficiently monitor particle size and movement
“Essentially, what we’re bringing to the table is a new approach to sensing information, very different to conventional cameras that have been around for many years,” says Luca Verre, CEO of Prophesee, the market leader in the field.
Whereas most commercial cameras are essentially optimised to produce attractive images, the needs of the automotive, industrial, Internet of Things (IoT) industries, and even some consumer products, often demand different performances. If you are monitoring change, for instance, as much as 90% of the scene is useless information because it does not change. Event cameras bypass that as they only monitor when light goes up or down in certain relative amounts, which produces a so-called “change event”.
In modern neuromorphic cameras, each pixel of the sensor works independently (asynchronously) and records continuously, so there is no downtime, even when you go down to microseconds. Also, since they only monitor changing data, they do not monitor redundant data. This is one of the key aspects driving the field forward.
Innovation in neuromorphic vision
Vision sensors typically gather a lot of data, but increasingly there is a drive to use edge processing for these sensors. For many machine vision applications, edge computation has become a bottleneck. But for event cameras, it is the opposite.
More and more, sensor cameras are used for some local processing, some edge processing, and this is where we believe we have a technology and an approach that can bring value to this application“More and more, sensor cameras are used for some local processing, some edge processing, and this is where we believe we have a technology and an approach that can bring value to this application,” says Verre.
“We are enabling fully fledged edge computing by the fact that our sensors produce very low data volumes. So, you can afford to have a cost-reasonable, low-power system on a chip at the edge, because you can simply generate a few event data that this processor can easily interface with and process locally.
“Instead of feeding this processor with tons of frames that overload them and hinder their capability to process data in real-time, our event camera can enable them to do real-time across a scene. We believe that event cameras are finally unlocking this edge processing.”
Making sensors smaller and cheaper is also a key innovation because it opens up a range of potential applications, such as in IoT sensing or smartphones. For this, Prophesee partnered with Sony, mixing its expertise in event cameras with Sony’s infrastructure and experience in vision sensors to develop a smaller, more efficient, and cheaper event camera evaluation kit. Verre thinks the pricing of event cameras is at a point where they can be realistically introduced into smartphones.
Another area companies are eyeing is fusion kits – the basic idea is to mix the capability of a neuromorphic camera with another vision sensor, such as lidar or a conventional camera, into a single system.
“From both the spatial information of a frame-based camera and from the information of an event-based camera, you can actually open the door to many other applications,” says Verre. “Definitely, there is potential in sensor fusion… by combining event-based sensors with some lidar technologies, for instance, in navigation, localisation, and mapping.”
Neuromorphic computing progress
However, while neuromorphic cameras mimic the human eye, the processing chips they work with are far from mimicking the human brain. Most neuromorphic computing, including work on event camera computing, is carried out using deep learning algorithms that perform processing on CPUs of GPUs, which are not optimised for neuromorphic processing. This is where new chips such as Intel’s Loihi 2 (a neuromorphic research chip) and Lava (an open-source software framework) come in.
“Our second-generation chip greatly improves the speed, programmability, and capacity of neuromorphic processing, broadening its usages in power and latency-constrained intelligent computing applications,” says Mike Davies, Director of Intel’s Neuromorphic Computing Lab.
BrainChip, a neuromorphic computing IP vendor, also partnered with Prophesee to deliver event-based vision systems with integrated low-power technology coupled with high AI performance.
It is not only industry accelerating the field of neuromorphic chips for vision – there is also an emerging but already active academic field. Neuromorphic systems have enormous potential, yet they are rarely used in a non-academic context. Particularly, there are no industrial employments of these bio-inspired technologies. Nevertheless, event-based solutions are already far superior to conventional algorithms in terms of latency and energy efficiency.
Working with the first iteration of the Loihi chip in 2019, Alpha Renner et al (‘Event-based attention and tracking on neuromorphic hardware’) developed the first set-up that interfaces an event-based camera with the spiking neuromorphic system Loihi, creating a purely event-driven sensing and processing system. The system selects a single object out of a number of moving objects and tracks it in the visual field, even in cases when movement stops, and the event stream is interrupted.
In 2021, Viale et al demonstrated the first spiking neuronal network (SNN) on a chip used for a neuromorphic vision-based controller solving a high-speed UAV control task. Ongoing research is looking at ways to use neuromorphic neural networks to integrate chips and event cameras for autonomous cars. Since many of these applications use the Loihi chip, newer generations, such as Loihi 2, should speed development. Other neuromorphic chips are also emerging, allowing quick learning and training of the algorithm even with a small dataset. Specialised SNN algorithms operating on neuromorphic chips can further help edge processing and general computing in event vision.
The development of event-based cameras, inspired by the retina, enables the exploitation of an additional physical constraint – time“The development of event-based cameras, inspired by the retina, enables the exploitation of an additional physical constraint – time. Due to their asynchronous course of operation, considering the precise occurrence of spikes, spiking neural networks take advantage of this constraint,” writes Lea Steffen and colleagues (‘Neuromorphic Stereo Vision: A Survey of Bio-Inspired Sensors and Algorithms’).
Lighting is another aspect the field of neuromorphic vision is increasingly looking at. An advantage of event cameras compared with frame-based cameras is their ability to deal with a range of extreme light conditions – whether high or low. But event cameras can now use light itself in a different way.
Prophesee and CIS have started work on the industry’s first evaluation kit for implementing 3D sensing based on structured light. This uses event-based vision and point cloud generation to produce an accurate 3D Point Cloud.
“You can then use this principle to project the light pattern in the scene and, because you know the geometry of the setting, you can compute the disparity map and then estimate the 3D and depth information,” says Verre. “We can reach this 3D Point Cloud at a refresh rate of 1kHz or above. So, any application of 3D tourism, such as 3D measurements or 3D navigation that requires high speed and time precision, really benefits from this technology. There are no comparable 3D approaches available today that can reach this time resolution.”
Industrial applications of event vision
Due to its inherent advantages, as well as progress in the field of peripherals (such as neuromorphic chips and lighting systems) and algorithms, we can expect the deployment of neuromorphic vision systems to continue – especially as systems become increasingly cost-effective.

From tracing particles or quality control to monitoring vibrations, all with low latency, low energy consumption, and relatively low amounts of data that favour edge computing, event vision is promising to become a mainstay in many industrial processes. Lowering costs through scaling production and better sensor design is opening even more doors.
Smartphones are one field where event cameras may make an unexpected entrance, but Verre says this is just the tip of the iceberg. He is looking forward to a paradigm shift and is most excited about all the applications that will soon pop up for event cameras – some of which we probably cannot yet envision.
“I see these technologies and new tech sensing modalities as a new paradigm that will create a new standard in the market. And in serving many, many applications, so we will see more event-based cameras all around us. This is so exciting.”

Phew, amazing, how I saw the share price this morning... I didn't expect it...... in bed I thought 0.4 cents would be ok for me.... and now... we're at 0.341 cents.. .. somehow I think to myself, now I don't care either, I've been in the red for a long time anyway... I'm able to wait a long time and that's what I was planning to do anyway... well, it's the way it is now and I'm really relaxed... it no use getting upset... I'm looking forward to the podcast

Not from what I have been told...I personally think that the whole situation with LDA Capital is extremely messy, and at some stage I do
hope that the CEO will explain why the Board called it so early into 2023.
I have seen a (sort of) explanation as to how this LDA put option is supposed to play out, but the floor price set by Brainchip has me thinking,
Today is the first time I have noticed the ASX send a company a please explain notice, because the share price has dropped. I personally find their behavior totally absurd.
May I also say that I think that having Peter put himself out there on Linkedin was great! asking followers to comment on what they would like him to comment on, such a brave move, and going by the two or so comments suggests to me at least, many are too afraid to ask him anything because of fear of possibly being laughed at or realizing they are exposing themselves to someone who has an IQ way above the average shareholder, me included, and fear being embarrassed.
I can assure you, 100%, our founder will never judge you.
The upcoming podcast is yet another positive move by the company, we all want to hear from Peter and Anil (in my opinion) and I'd be very happy to have both our "top guns" make themselves available for half-yearly "fire side chats" throughout the year/s.
All staff are important, they all contribute and continue to contribute daily, but having our two key guys talking about our company in an honest relaxed manner is extremely uplifting for all shareholders, so every 6 months lets make it happen Brainchip, you're all appreciated.
Love Brainchip x

I’m inspired to load more tomorrow, the above
just nailed further convictionD
Did,not Sean say judge me by my next AGM, well the judge has spoken,time to go your only good enough to be a number two,overlooked for a reason,when the going get tough he hides, come out of your luxury Sydney expensive office and tell shareholders where we are really at with nda,s versus real potential paying customers,sick of listening to Tony Dawes bullshit. The minute you question all the free shares his demeanour changes. Won’t answer what they have achieved to earn them. FOS this lot.

She didn't sell. Only a loss when you do. Never fun when SP drops but not chrystallised until you capitulate and sell out. We all got excited on the rise to 2.34 and I never expected we'd go below $1 again but hold the faith - we invested for a reason.

Off you go and join the backslapping crew. All is well and theres nothing to see here.
Unbelievable. Pass the cool aid.
I'll continue to comment for as long as I please. Put me on ignore. if you can't handle reality.

Good luck if this is how you view your investments.
I have been invested in the company since 2015 so I suppose I'm not long term enough for you?
Are you saying I can't respond how I like to a long term holder like Lou?
Buffett 101, Please stop. You're the one embarrassing yourself with the self help investment books. Amateur hour here.

Hi Everyone
Just in regards to shorters, I'm trying to understand the way they work.
My understanding, which I could be completely wrong so please correct me.
They borrow a heap of shares, do they sit on them and then decide when is a good time for them to sell them, they then sell a massive amount so as to spook the market, triggering stop losses, thus this reduces the SP all the more and then when they think they've hit rock bottom they quickly buy back in so they can then return the borrowed shares? If this is the case then can we expect some frantic buying from them over the next couple of days/weeks, which should recover the SP?
Also thinking about the SP, I've been in since my baby girl was born, she's now 10, I see there are a lot of people here who are not happy about the SP and it seems that this is their only focus. I'm curious say if the SP had shot up to $1, would you sell or hold knowing what the potential is for BRN, I know I wouldn't sell, if you would still hold how is that any different to holding now. I appreciate some may need the money now which if that is the case I feel for you. I think people were expecting to see revenue towards the end of last year but the plan changed from a Chip supplier to selling IP which meant changes had to be made which took time to implement. I think that we could all agree that this will be far more beneficial for BRN in the long run.
Happy to be corrected, I don't often contribute here so please don't shoot me!
Thank you to all the great posts and finds, they are very much appreciated.
Also sorry if a similar question has already been asked about shorters.

Get a mention on the Prophesee partnership in the article which is a general discussion with Verre as well.
Yes, saw as a demonstrator but with desire for commercial relationship possibly too. Makes sense when read first paragraph.

Neuromorphic computing progress
However, while neuromorphic cameras
mimic the human eye, the processing chipsthey work with are far from mimicking the human brain. Most neuromorphic computing, including work on event camera computing, is carried out using deep learning algorithms that
perform processing on CPUs of GPUs,
which are not optimised for
neuromorphic processing.
This is where new chips such as Intel’s Loihi 2 (a neuromorphic research chip) and Lava (an open-source software framework) come in.“Our second-generation chip greatly improves the speed, programmability, and capacity of neuromorphic processing, broadening its usages in power and latency-constrained intelligent computinga pplications,” says Mike Davies, Director ofIntel’s Neuromorphic Computing Lab.
BrainChip, a neuromorphic computing
IP vendor, also partnered with Prophesee to deliver event-based vision systems with integrated low-power technology coupled with high AI performance.

Smartphones are one field where
event cameras may make an unexpected
entrance, but Verre says this is just the tip
of the iceberg. He is looking forward to a
paradigm shift and is most excited about all the applications that will soon pop up forevent cameras – some of which we probablycannot yet envision.
“I see these technologies and new tech
sensing modalities as a new paradigm that will create a new standard in the market. And in serving many, many applications, so we will see more event-based cameras all around us. This is so exciting.”

Why you will be seeing much more from event cameras | Imaging and Machine Vision Europe
Advances in sensors that capture images like real eyes, plus in the software and hardware to process them, are bringing a paradigm shift in imaging, finds Andrei Mihai

Legal shorting involves the shorter borrowing th shares at $x per share in the hope that the share price will fall. If the share price falls to, say, $y, where y<x, they can buy shares at $y to return them to the lender, making $(x-y) per share profit.
However, if the share price rises to $z per share, where z>x, the shorter can face a loss of $(z-x) per share.
The practice you mention of manipulating the share price down by selling shares below what would be the market price is illegal and widespread on the ASX.
One indicator is if the SP often falls on close or in the after-market auction.
The practice is facilitated by bot trading, where computers sell small numbers of shares to continuously edge the SP down. Bot trading can also be tantamount to insider trading in that the large brokers can monitor incoming bids and make a purchase or sale before the bidders transaction is fulfilled.
Both short selling and bot trading should be banned as they are tools for picking the pockets of unsophisticated share holders.
It would be interesting to see how much the brokers donate to political parties.

Some info for you. Hope you get something from them.
Short selling is obviously an allowable transaction in the normal course of trading and can also be used for hedging but also by so called activists.
Short Selling: Pros, Cons, and Examples
Short selling occurs when an investor borrows a security, sells it on the open market, and expects to repurchase it for less money.
Activist shorting is the same mechanism but can be driven differently as per the ASIC explanation and link below.
Activist short selling campaigns in Australia
This information sheet (INFO 255) outlines the practice of activist short selling campaigns in Australia and ASIC's expectations to promote market integrity during these campaigns. It:- briefly explains what activist short selling is
- describes the impact of activist short selling on markets
- provides an overview of the Australian regulatory framework relevant to these campaigns
- recommends better practices for activist short sellers and authors of short reports, market operators, target entities and market participants
- lists some of the actions that we may take in response to these campaigns.
What is activist short selling?
Short selling
People sometimes sell (short sell) financial products they do not own with a view to repurchasing them later at a lower price.Generally, where a person executes a short sale and relies on an existing securities lending arrangement to have a 'presently exercisable and unconditional right to vest' the products in the buyer at the time of sale, the sale is a covered short sale. Covered short selling in section 1020B financial products (e.g. securities, bonds and managed investment schemes) is permitted under the Corporations Act 2001 (Corporations Act).
Short selling without a securities lending arrangement is known as 'naked short selling' and is generally not permitted in section 1020B products in Australia. More information on short selling can be found in RG 196.
Activist short selling
Activist short selling involves a person taking a short position in a financial product and then publicly disseminating information (e.g. one or more reports) directly or through an agent to negatively impact the price of the product ('short report'). A short report may, for example, criticise an entity's finances, management, public disclosures or future prospects. A short report does not necessarily have to be in the form of a formal report. It could be, for example, a post on a social media platform, blog or online forum. The activist short seller expects the short report to cause the price of the financial product to fall, enabling them to realise a profit.Activist short selling campaigns are not new. Over time, they have received more attention with online news and social media outlets providing instantaneous access to a broad audience. This can exacerbate the speed and depth of the market's response to a short report.
Most campaigns against Australian entities have been by overseas activist short sellers that caveat their reports as not intended for an Australian audience. In practice, online distribution and reporting of campaigns by Australian media mean the reports (or their key messages) are widely accessed by Australians.
Our research indicates that activist short selling campaigns tend to target entities with complex and opaque corporate structures and accounting practices, or poor disclosure. They also tend to target companies with lower market capitalisation. There is also a tendency to follow cyclical trends (e.g. to target entities and industries that are high growth/high risk or may be overvalued or have experienced rapid security price growth). They may also target sectors that are technically complex and/or easily misunderstood (e.g. medical research, technology and mining).
Impact of activist short selling
Investors expect to transact in a fair and informed market. When activist short sellers provide accurate and meaningful new information, they can have a positive impact on price formation and market integrity as they may counterbalance excessive market optimism.Short reports can provide new research and analysis and test the veracity of information released by a target entity.
Some activist short sellers have exposed flawed business models, questionable business or accounting practices, insolvency and fraud in targeted entities.
However, activist short sellers can also unduly distort the price of a target entity's securities. For example, by making false or misleading statements, providing an incomplete view of the facts, drawing conclusions unsupported by adequate evidence or by using overly emotive or inflammatory language to distort the facts ('short and distort' campaigns).
Short reports are often released during trading hours for maximum and immediate effect on the price of the target entity's securities. The time taken:
- to request and implement a trading halt, and
- for the target entity to issue a response,
If the claims in a short report appear plausible or if the market suspects the target entity is subject to a 'short and distort' campaign (regardless of the plausibility of the short report claims), they can cause significant and immediate security price volatility. Other investors may be induced into selling the target entity's securities for less than their true value, potentially resulting in financial loss. If the price fall is as a result of a false or misleading statement, this can undermine investor confidence in the market and may affect their willingness to participate in the future.
This activity can also harm the reputation of the target entity. In addition to creating doubt in the minds of existing shareholders, it may discourage future investors, negatively influence future valuations and the price of the target entity's securities, and impact the target entity's ability to raise capital.
