Systems and Methods for Remote Interaction with Portable Field Measurement Equipment Running a Soil Test from Your Phone

This patent describes a controller that sits between a technician’s phone and a piece of portable field testing equipment, letting the operator run the test remotely, capture the results automatically, and push them to a database. It comes from Engeo Incorporated, a Californian geotechnical and civil engineering firm with offices in Australia.

The Problem

Before a road, a slab or a building can be signed off, the materials underneath have to be tested. Some of that testing can be done by taking a sample back to a laboratory, but a great deal of it has to happen in situ, at the exact spot in question, because what matters is how the material behaves where it lies. A range of portable instruments exists for this: devices that measure the moisture and density of compacted fill such as soil, sand, aggregate and asphaltic concrete, and others that assess concrete and reinforcing steel.

The problem is the human in the loop. A technician stands over the instrument, operates it by hand, reads a value off a small display, writes it into a notebook or a form, and types it into a system later. That is slow, it is error-prone at every transcription step, and it puts a person physically at the device for every reading, which can mean standing in live traffic, in a trench, or on a compacting fill surface. It also means the data reaches the engineers who need it hours or days after it was collected. Some of these instruments, particularly nuclear density gauges, carry their own handling and licensing burdens that make remote operation attractive for reasons beyond convenience.

What This Invention Does

The system inserts a controller between the operator and the instrument. The controller couples to a mobile device, receives user input from the technician through that device, and causes the portable field measurement device to execute the operations the user has directed. It then electronically records the data output that results from those operations, and reports the data back to the user on the mobile device and to a remote electronic database.

In some described embodiments a robotic arm is used to physically actuate the measurement device, which extends the idea from remote control of an instrument’s electronics to remote operation of instruments that need a physical action, such as a trigger pull or a probe insertion. The effect is to close the loop between the field and the office: the reading never exists only as a number on a handheld screen, it is captured at the moment of measurement, tagged and sent, so the transcription step and its errors simply disappear.

Key Features

• Mobile device coupling. A controller couples to a standard mobile device that serves as the operator interface.
• Remote operation. User input on the mobile device causes the field measurement device to execute the directed operations.
• Automatic data capture. Output from the measurement device is recorded electronically rather than transcribed by hand.
• Dual reporting. Data is reported both back to the user and to a remote electronic database.
• Robotic actuation option. A robotic arm can physically actuate the measurement device where an action is required.
• Broad instrument coverage. The approach suits the range of portable devices used on soil, aggregate, concrete and reinforcing steel.

Who Is Behind It

The applicant is Engeo Incorporated, an employee-owned firm founded in 1971 and based in San Ramon, California, with more than 400 geotechnical and civil engineers, geologists, GIS specialists, environmental scientists and laboratory staff, and offices in California, Nevada, Washington, Guam, New Zealand and Australia. The named inventors are Gilead Wurman, Michael John Price and Joseph Gray. The application sits in a chain of Australian divisionals connected to applications 2019383358 and 2024227660, with priority from November 2018.

Why It Matters

Construction quality assurance is one of the last parts of the building process still running largely on paper and hand-typed spreadsheets, and it is precisely where errors are expensive, because compaction and material testing determine whether a road or a foundation performs for decades. Australia’s infrastructure pipeline keeps a large field-testing workforce busy, and the applicant already operates here, so a system that reduces both transcription error and time spent standing beside an instrument has an obvious local application. There is a safety dimension too: any measurement that can be taken from a few metres away is one fewer reason to put a technician next to moving plant.
