Canon Patent Application: Improving High-Speed Camera Stability.

[Canon Rumors]

Reading through this patent application (2024-022343) was a “huh, I never thought of that” moment. Canon in this patent is concerned that when some of its high-speed sensors go full out, they draw too much current from the battery causing the voltage to dip. If the voltage dips under certain amounts, there’s not enough voltage

If it's only the capacitor I am not shure that this can be patented. Using capacitors to stabilize voltages during high current draw is such a standard.
Maybe they have invented some circuitry which can incorporate a capacitor in a step-up/step-down regulator with extremely high efficiency and stability?

I couldn't find any relevant data on Cnaon's latest sensors

minor boo-boo

This has been done in hearing aids since 2010*. Not a new technology as such. But it might still be patentable if they can argue that the 'inventive step' is doing it in a Camera setting.

*) Zinc-Air batteries for hearing aids (10A, 312, 13, and 675) can sustain ludicrously low currents, so you have to use a trick like this to support a 2.4GHz radio which draws way more than what the Zn-Air battery can deliver. The internal impedance of 8-12 Ohms doesn't help either.

A "Patent Application" does not imply that a patent was issued. Reducing the resistance would be a more efficient method, for power lines in circuits perform better with low gauge high resistance wires. And even more efficiently from the backside, a new technology playground, already being looked into by Samsung, Intel and TSMC. Backside power!

The sky is blue. Gravity exists. Did you have a point, other than stating the obvious? I don’t see that Richard implied anything different, he went so far as to put ‘application’ in the title of the post.
