Ravens — Self-Reporting Asset Beacons

Attach a Raven to any asset and it reports its own location to Forager on a schedule or when moved — automatically, with no staff involvement and no connection to your corporate network.

Named for Huginn and Muninn

In Norse mythology, Odin's ravens flew out each morning to observe the world and returned to report everything they had seen. These devices do exactly that — attach one to any asset and it scouts its own location on a schedule or whenever in motion, while the rest of your operation runs without interruption.

How Ravens work.

  • 1. Wake
  • 2. Scan
  • 3. Report
  • 4. Sleep
On a configurable schedule (every 15 minutes, 30 minutes, or hourly) or whenever the asset is moved, the Raven wakes from deep sleep. Its integrated accelerometer detects motion to trigger updates while the asset is in transit, returning to sleep when stationary to conserve battery. No staff trigger required.
The Raven passively reads the ambient RF environment — the Wi-Fi access points and BLE devices visible from wherever it is. It never connects to the network, never authenticates, never transmits on the hospital's infrastructure. It just listens and records what the radio environment looks like from that location.
The Raven sends its scan data to a nearby Gateway — a small device installed in the drop ceiling of a hallway. The Gateway routes the payload to the Forager backend over a cellular connection. Forager compares the scan against its RF fingerprint database and determines which room the asset is in. The asset's location record updates automatically.
Transmission complete, the Raven returns to deep sleep until its next scheduled wake. Power draw during sleep is negligible — the battery lasts weeks between swaps, and for assets that are regularly plugged in, an AC passthrough option keeps the Raven perpetually charged.
Ravens are RF environment sensors, not simple identifier beacons. The difference matters: an identifier beacon tells you "this tag is somewhere in this building." A Raven tells Forager exactly which room the asset is in — because it reads the same ambient RF signals that Forager's fingerprint database was built from.

No network integration required. Ravens don't touch your corporate infrastructure. No IT approval. No InfoSec review. No VLAN allocation. Plug in a Gateway, attach Ravens to assets, and location data starts flowing.

What you're installing
01
Ravens (asset nodes)
Matchbox-sized beacons that attach to any asset with a cable tie or adhesive pad. Battery-powered. Field-swappable battery. IP67 sealed enclosure rated for hospital cleaning agents. No tools required for installation or battery swap.
02
Gateways (ceiling nodes)
Small AC-powered devices installed in drop ceilings or mounted high on hallway walls. Each Gateway serves a coverage area, receives scan data from Ravens nearby, and routes it to the Forager backend over cellular — independent of your corporate network.

Installation takes hours, not months.

Gateway approval goes through Facilities — not InfoSec. Attaching Ravens to assets requires no credentials, no programmer, and no IT involvement. A technician with a phone and a bag of Ravens can cover a floor in an afternoon.

Where Ravens earn their keep.

Forager's manual presence confirmation is fast and effective for assets your team visits regularly. Ravens extend that coverage to the assets that fall through the cracks.

High-movement assets

Carts, portable equipment, and shared devices that change locations multiple times a day. Manual confirmation can't keep up. Ravens report in continuously without anyone picking up a phone.

Hard-to-reach locations

Equipment in storage rooms, back-of-house areas, and maintenance closets that staff rarely pass through. Ravens keep location records current between visits — even for assets that go untouched for weeks.

High-value assets

For equipment where continuous location awareness justifies the hardware cost — infusion pumps, imaging accessories, specialty carts — Ravens provide ongoing presence reporting instead of point-in-time snapshots.

Compliance-critical inventory

Assets that must be located on demand for audits and inspections. A Raven-tracked asset has a fresh location record every 15 minutes — not "last confirmed by a tech three weeks ago."

Lean staffing environments

Facilities where manual scan cadence is limited by headcount. Ravens operate regardless of scheduling, staffing levels, or shift coverage — location data doesn't depend on a person walking the floor.

After-hours monitoring

Ravens scan on schedule around the clock. Overnight movement of an asset that shouldn't be moving is visible in the dashboard the next morning — without anyone being on-site to observe it.

Three SKUs for three environments.

Battery power handles the majority of deployments. AC charging options exist for assets that live near an outlet.
First to market

Raven Battery

Field-swappable 18650 battery. No outlet required. Mounts to any asset with a cable tie or adhesive pad. IP67 sealed enclosure withstands hospital cleaning agents.

Target environments: Any — clinical areas, storage rooms, hallways, portable equipment.

Second SKU

Raven AC

AC passthrough adapter sits between the asset's power cord and the wall outlet. The device's full power passes through untouched — the adapter siphons a few watts to keep the Raven battery perpetually charged.

Target environments: Storage rooms, equipment staging areas, AV closets, maintenance bays. Not for patient-adjacent clinical areas.

Third SKU

Raven Medical AC

Same AC passthrough concept with a medical-grade power supply that meets IEC 60601-1 electrical safety requirements for patient-adjacent environments. Perpetually charged for powered medical equipment.

Target environments: Clinical areas, patient-adjacent environments, powered medical equipment.

Ravens extend your Forager deployment.

Ravens don't replace Forager's manual presence confirmation workflow — they extend it. From the Forager dashboard's perspective, a Raven update and a staff member scan are the same type of event: asset confirmed in room, timestamp, source attributed.

The same floor plan visualizations, compliance reports, and attestation logs that Forager already generates work identically for Raven-tracked assets. No new dashboard. No separate system. No parallel database.

If you're already running a Forager deployment, Ravens add continuous coverage on top of the RF fingerprint infrastructure you've already built. The rooms you've surveyed are immediately available for Raven location matching — no additional setup required.
