High dynamic range of neuromorphic camera: (a) Image of the Trapezium cluster formed by accumulating events in 200ms window from the neuromorphic camera with a slewing telescope, where red represents positive events and green indicates negative vents. (b) Optical image of the Trapezium star cluster observed through the Hubble Space Telescope [86]. (c) Image of Vega and a nearby faint star, ∼ 200′′ apart, demonstrating a dynamic range exceeding 100dB. (d) High dynamic imaging of star Betelgeuse, with a neighbouring faint star visible at roughly ∼ 170′′ distance. — astro-ph.IM
To deepen our understanding of optical astronomy, we must advance imaging technology to overcome conventional frame-based cameras’ limited dynamic range and temporal resolution. Our Perspective paper examines how neuromorphic cameras can effectively address these challenges.
Drawing inspiration from the human retina, neuromorphic cameras excel in speed and high dynamic range by utilizing asynchronous pixel operation and logarithmic photocurrent conversion, making them highly effective for celestial imaging.
We use 1300 mm terrestrial telescope to demonstrate the neuromorphic camera’s ability to simultaneously capture faint and bright celestial sources while preventing saturation effects.
We illustrate its photometric capabilities through aperture photometry of a star field with faint stars. Detection of the faint gas cloud structure of the Trapezium cluster during a full moon night highlights the camera’s high dynamic range, effectively mitigating static glare from lunar illumination.
Our investigations also include detecting meteorite passing near the Moon and Earth, as well as imaging satellites and anthropogenic debris with exceptionally high temporal resolution using a 200mm telescope. Our observations show the immense potential of neuromorphic cameras in advancing astronomical optical imaging and pushing the boundaries of observational astronomy.

Much of this seems to relate to the DVS side of neuromorphic. It discusses the performance characteristics of the pixels:
"asynchronous pixel operation and logarithmic photocurrent conversion"
"simultaneously capture faint and bright celestial sources"
However, there may be a role for SNN with motion detection:
" detecting meteorite passing near the Moon and Earth, as well as imaging satellites and anthropogenic debris with exceptionally high temporal resolution"

Qualcomm files antitrust complaints against ARM around the world
Business news | March 27, 2025By Peter Clarke
SILICON ARTIFICIAL INTELLIGENCE ANALOG EDA & CAD TOOLS SEMICONDUCTOR
Qualcomm Inc. (San Diego, Calif.) has filed complaints alleging anticompetitive practices by processor IP licensor ARM Holdings plc with the European Commission, the US Federal Trade Commission and Korea Fair Trade Commission.
Bloomberg reports that Qualcomm’s complaint is that ARM – which has operated an open and equitable intellectual property licensing regime for more than 20 years – is now restricting access to technology and exploiting its market dominance as it prepares to operate in competition with its customers.The multiple filings come after Qualcomm successfully defended itself in a lawsuit filed by ARM in a Delaware court.
In December 2024 the jury found that Qualcomm’s latest AI-PC processors, based on the ARM instruction set, were properly licensed and did not need a separate license to be negotiated. The formal result was a mis-trial, which left Qualcomm free to continue selling its Snapdragon X processors based on the Oryon core for now, but also left the way open for Arm to seek a re-trial, which it is expected to do.
In the trial it was revealed that CEO Rene Haas had written a strategy paper indicating ARM could start designing its own chips. Haas responded that as CEO it was his job to consider multiple possible courses of action and that this one has not been implemented.
Since then it has been reported that ARM is designing a CPU for data centers as a “chip platform” that will be customizable for multiple customers with Meta as the first.

The question this begs for me is whether it indicates a return to ASIC manufacture or whether this is to be offered as a service to a customer/customers...........3 more roles have been advertised within the last 2 days. Here is one of them:

I think it's for clients.
The nature of our business is changing and our staff mix and levels will change with this.
We were made aware at the last AGM that there were many engagements which as they become 'serious' will require serious liaison from engineers/project managers.
I note that week we advertised for a Manager to oversee SBIR projects we are involved with.
It all shows we are moving into the next phase.

That's like saying you will save energy for the finals when you are losing your game in semi-final 0 vs 5...I have this vague feeling that they are holding back any announcements that would lead to a rise in the stock price ( if there is any at all) until after the transfer to the USA, meaning after the RS. It would have been too good to be true… Can anyone provide a counterargument? I’d welcome that.
they need to show us that they are actually winning. We need to see some $$$$$$$... right now, we have almost nothing compared to our staff numbers, they would make more money if we send them to Maccas to flip burgers...

Of course, one shouldn't take such a post seriously. Right now, I'm just taking it with a touch of sarcasm and irony. I do think something should come before the AGM. Or let's say, I hope so.
In that case, I have a feeling that they will wait till AkidO9999....
Did anyone else notice that Sean mentioned Heart when talking about Wearables. The big talk of course was the Onsor Epilepsy detector.#edgeai #wearables #ai | BrainChip

Tata released a paper on a heart issue device for early detection of heart issues.
No doubt we have a project engineer working with Tata.
2022/23 was our year to incentivise Key Management personnel (KMP).
2022/23 total realised remuneration for KMP was $8,120,967.
2023/24 total realised remuneration for KMP's was $4,404,575.
Total decrease of $3,716324 in one year.
Basically mostly reflects incentivising the BOD in 2022/23 via a stake in the business.
Both Sean and Tony V are in the top 50 holders and set to move higher.
I think we are already seeing some results from 2022/23 and earlier engagements.

There is hope. I asked Gemini a ridiculous question and got a surprise answer:
"AKIDA technology, developed by BrainChip, is an advanced neural processing unit designed for edge AI applications2. While its primary uses include object detection, data analytics, and event-based learning, it could theoretically be adapted for medical or cosmetic purposes, such as detecting male pattern baldness. By analyzing visual data or other biomarkers, AKIDA could potentially identify early signs of hair loss and suggest interventions."
Is there no limit to AKIDA????
A mirror and reluctant acceptance might be an alternative.
PS: I am not bald just shedding.
It's Friday afternoon after all.................
