SENSOR STUDY
Fewer readings. Less heat to remove.
In case a1-1-100_b48, readings fall from 48 to 23 at the same required estimate quality. Readings use 50% of the original task energy; planning adds 3%. In the normalized example, input falls from 1 J to 0.769583333 J. The exact conventional planner reaches the same reading counts.
The cooling model takes all 10 W of starting input as heat through this path, with zero energy leaving in forms other than heat and zero change in stored energy. The cooler has 50 g fixed and 150 g scaled with effective area at the same heat transfer and temperature rise. Added permanent parts: 0 g. Net mass saved: 34.5625 g. The calculator retains these inputs so you can inspect or replace them.
The adaptive-optics reference below models a separate actuation job.

Both designs return the same required output fields, encoded response bytes and final state within this defined model. Each job contains 4 useful frames and repeats every 0.5 ms.
Input power: 1.250736886 → 1.249726537 W at 2,000 jobs/s. ΔQ̇ = (Eordinary − Eselected) / job period, for equal energy leaving in forms other than heat and equal stored-energy change. The input-power model includes the unchanged reference load and shared costs.
Ordinary → selected completion: 97.64 → 130.11 µs; required deadline 400 µs.

Operating conditions, uncertainty and fitting the design into a product
One reference controller/processor, shared memory, sensor/clock rails and the stated unchanged external load; compute-specific increments and added resources are priced by the R5 common cost-law artifact.
Supply efficiency in the model: 90%. Shared loads and loads that stay unchanged: common host control W 0.02 W; common memory W 0.005 W; common clock sensor W 0.01 W; plant or external load W 1 W.
- Application-specific force/flow/torque/trajectory plant and accepted settling/stability constraints
- R(T), inductance/coenergy or relevant pump/motor/piezo constitutive maps
- Driver switching, mechanical work and all retained loss maps at equal service
- Controller state/history, safe fault behavior and recovery sequence
The portfolio has 13 savings at the main modeled point, 100 ties using the conventional fallback, and 7 unmatched comparisons across 120 references. Positive advantages passing both the strict and combined tighter uncertainty tests: 0.

Calculate the cooling mass.
Use the heat carried by this cooling path and the weight of its installed parts, including added hardware. The comparison task’s average power change contributes to that total device calculation.
Chosen model: effective area follows Q = hAΔT; the fixed mass stays, the area-scaled mass changes, and added parts are charged.
34.5625 g net cooling mass saved
200 g → 165.4375 g. Effective area: 500 → 384.79167 cm².
