Filled Example: Software (API Rate‑Limit Orchestrator)
- Title: Adaptive multi‑tenant rate‑limit orchestrator for bursty workloads
- Summary: Coordinates per‑tenant budgets across services using token‑bucket fusion and predictive smoothing, reducing tail latency p99 from 120ms→40–55ms at 80% utilization.
- Background: Existing per‑service limiters create global head‑of‑line blocking; prior art lacks cross‑service coordination under bursty traffic.
- Technical Description:
- Architecture: gateway → orchestrator → per‑service shim; consistent hashing by tenant; Redis for shared budgets; time‑quanta 10–50ms.
- Algorithm: hybrid token bucket + EWMA demand predictor; backoff jitter 5–20ms; fairness clamp 0.2–0.8.
- Embodiment: with N=5 services, 20 tenants, workload X, utilization 0.8, observed p99 45ms; acceptance: p99<60ms, no tenant starvation.
- Variants: single‑tenant mode; predictive off; window sizes 5–200ms; storage swap (Memcached, in‑proc).
- Diagrams: Fig.1 block diagram; Fig.2 sequence of grant/deny.
- Attachments: API spec v1.2, k6 scripts v0.9, dashboards links.
Filled Example: Medical Device (Wearable SpO₂ Sensor)
- Title: Low‑power reflective PPG array with motion artifact suppression
- Summary: A tri‑wavelength reflective PPG with adaptive illumination and IMU‑assisted artifact filtering; achieves ±2% SpO₂ RMSE during jogging.
- Background: Conventional single‑LED PPG suffers motion artifacts; prior art lacks synchronized IMU fusion with per‑site calibration.
- Technical Description:
- Materials: biocompatible silicone strap; LED 530/660/940nm; PD with gain stages; MCU at 32MHz.
- Parameters: LED duty 2–8%; sampling 200–500Hz; IMU 6‑axis at 100–200Hz; window 1–3s.
- Embodiment: treadmill protocol n=12; reference MASIMO; RMSE 1.9%; acceptance: RMSE≤2.5% across HR 60–160.
- Variants: transmissive mode; dual‑site fusion (wrist+finger); LED wavelength swap.
- Diagrams: placement drawing; signal chain.
- Attachments: bench logs, calibration script v0.3, risk table.
Filled Example: Biotech (Enzyme Variant for Cold Wash)
- Title: Protease X mutant with retained activity at 4–8°C
- Summary: Variant maintains ≥70% activity at 6°C enabling cold‑chain compatible wash step.
- Background: WT loses activity <12°C; literature variants unstable in detergent.
- Technical Description:
- Host: E. coli BL21(DE3); vector pET‑28a; inducer IPTG 0.1–0.5mM.
- Buffer: pH 7.2–7.6; NaCl 150–250mM; detergent 0.05–0.2%.
- Assay: fluorogenic substrate; readout RFU/s; control WT; n=3; activity curve 4–25°C.
- Acceptance: activity≥70% at 6°C; stability 24h.
- Variants: mutations at positions 87/132/215; Ca²⁺ cofactor 0.5–2mM.
- Attachments: sequencing IDs, lab notebook refs.
