Units spaced along a road log every passing vehicle with direction, speed and size, confirmed across every unit in the line. The same layout works at a mine haul road, a site entrance or an airfield service-road crossing.

Units along an access road, fence or quay detect a vehicle, place it along the line and cue a PTZ camera to it, then follow it. Outputs: webhook, CEF/syslog, ONVIF, Axis VAPIX. A vehicle sensor at fence range, labelled as such.

A hold-line monitor for runway incursions, with passive vehicle detection at the chokepoint, plus GIC space-weather awareness for the airfield.

Sign in, see the sessions your units recorded by day, and replay one on the satellite map: the real units and the 2-D localizer's dot moving, parking and refusing as the live gate showed it. Recorded data, replayed through today's code. Nothing simulated.

A country-wide network of stations as one instrument: station health and gaps, the shared geomagnetic variation, each station's local residual, temperature-compensated channels, and IAGA-2002 export.

Walk a unit along survey lines with a second unit as base station: diurnal-corrected total-field maps, gradients, and depth estimates for mineral exploration and pre-dig work.

Invert a line of surface sensors to pinpoint a buried source's position and estimate its depth, with confidence.

Reconstruct the field over an area and localize a source in x, y and depth. Point sensors become an imager.

A synthetic sensor mesh re-solves a moving source's position each frame, with rolling error and confidence. The same solver runs live at the gate.

Where a magnetic tool is inside a long non-magnetic tube (a sputtering head in a 14 m coating tube), from four or five units fixed along the outside. A dipole fit each second gives position along the tube with its own ±, strength and attitude, and across the bore when units sit around the tube. Demo on simulated units; live on real ones over Wi-Fi.

Estimated quasi-DC current in a transformer's neutral grounding conductor from one unit fixed beside it, read against local dB/dt and live NOAA Kp: events, their lag-correlation and a per-site empirical proxy. Calibrated on site and labelled estimated. It only watches: not a protection relay, a GIC-blocking device or a compliance instrument.

Non-contact current on a 125 VDC substation battery from one unit beside one pole's cable: charging, float or discharging, and the float-current trend that says which bank to visit. Estimated, calibrated on site. Not a cell-voltage or electrolyte-level sensor.

Register your substations and station-battery banks. The board ranks which bank to visit next from the recordings and calibrations you already have: discharging at the last reading, float current rising, uncalibrated, or not looked at in 30 days. Amps are estimates calibrated on site; no calibrated recording means “no current data”.

The same analyzer the battery and GIC pages run, on simulated samples of a DC conductor at a known current: the field step it measures against the Biot–Savart step the geometry predicts. Simulated data, real physics. The calibration proof-point for non-contact current.

Live magnetic field with a real FFT spectrum and scrolling spectrogram: 50/60 Hz harmonic and EMI fingerprinting.

Learn a machine's healthy signature, then catch bearing-fault drift early with a trend-based health score.
