We build technology. We test hypotheses.

Intelligent Software with purpose.

We develop specialized software for building automation, business integration, measurement, data analysis and experimental research tools.

PICALLW — Technology, Research & Intelligent SoftwareFrom field automation and HMI to measurement, data analytics and experimental research systems.

TWO CLEAR PATHS

Products & engineering. Research & experimental technology.

PICALLW separates production tools and custom development from research projects where hypotheses, methods and limitations are explicitly identified.

PRODUCTS & ENGINEERING

Software for real-world use.

Products and development for automation, HMI, business workflows, integration, data and reporting.

TYPICAL USE CASES

From a problem to a usable tool.

These examples describe typical ways PICALLW technologies can be used and are not presented as customer case studies.

01 · BUILDING AUTOMATION

From field point to operational HMI

Problem: Multiple protocols, scattered points and time-consuming visualization setup.
Solution: NODVIA Field discovers and checks data, Studio designs the HMI, Cloud publishes it and View runs it on an Android touch panel.
Technologies: BACnet · Modbus · KNX · M-Bus · Climatix · Android HMI
Result: A shorter, more traceable path from field diagnostics to a usable operator screen.

02 · BUSINESS SOFTWARE

Data, users and reports in one workflow

Problem: Manual transfers, spreadsheets and information spread across disconnected systems.
Solution: A purpose-built web or Windows application with a database, users, API integration and automated reporting.
Technologies: Web · Windows · SQL · API · integrations · reporting
Result: One workflow, less manual re-entry and repeatable report generation.

03 · MEASUREMENT RESEARCH

Measurements gain context over time

Problem: A single measurement without context on quality, repeatability or the person's own baseline.
Solution: GDV Studio combines image analysis, comparisons and trends with optional HRV/ECG context.
Technologies: GDV/EPI · HRV · ECG · image analysis · longitudinal data
Result: More transparent comparison over time and clearer separation of signal, variability and interpretation.

LIVE RESEARCH PROJECT

World State Explorer — the world as a multidimensional time series.

A public PICALLW research environment for exploring repeatable relationships among financial, geomagnetic, weather, lunar, seismic and collective signals.

ACTIVE RESEARCHPUBLIC EXPLORER

Discover → Validate → Replicate.

World State Explorer is designed to search for relationships that can be tested on unseen data rather than manufacture spectacular conclusions. It combines the World State Vector, lag analysis, Mutual Information, similar historical states and false-discovery control.
