## Abstract

A portable sensor calibration device that provides a reference to a sensor during a calibration procedure. The sensor calibration device may have a umber of adjustable functions providing for functional configurability, such as interchangeable target elements, adjustable pitch, adjustable target mounting, and locking elements.

## Claims

### Claim 1

A sensor calibration device comprising the following components:
a base frame;
a standing flame operable to couple with the base frame such that the standing frame is substantially transverse to the base frame;
a measurement frame comprising a primary measurement member and a secondary measurement member affixed to the primary standing member transversely, the measurement frame operable to couple to the standing frame such that the primary measurement member is substantially parallel to the primary standing member;
a mounting bolster comprising an elongated member, the mounting bolster operable to detachably couple to the measurement frame such that the mounting bolster is substantially parallel to the primary measurement member;
a crossbar configured to detachably couple to the mounting bolster; and
a target configured to detachably couple to the crossbar, the target suitable for a sensor calibrations.

### Claim 2 (depends on 1)

The sensor calibration device of claim 1, wherein the mounting bolster comprises a bolster pin operable to retain the mounting bolster on the measurement frame.

### Claim 3 (depends on 1)

The sensor calibration device of claim 1, wherein the mounting bolster is operable to adjustably couple to the measurement frame, the adjustment comprising a variable position of the mounting bolster with respect to a longitudinal length of the primary measurement member.

### Claim 4 (depends on 1)

The sensor calibration device of claim 1, wherein the mounting bolster further comprises a support pin operable to support the target.

### Claim 5 (depends on 1)

The sensor calibration device of claim 1, wherein the crossbar detachably couples to the mounting bolster using a magnetic coupling.

### Claim 6 (depends on 5)

The sensor calibration device of claim 5, wherein the target detachably couples to the crossbar using a magnetic coupling.

### Claim 7

An assembled sensor calibration device comprising:
a base frame;
a standing frame coupled to the base frame such that the standing frame is substantially transverse to the base frame;
a measurement frame comprising a primary measurement member and a secondary measurement member affixed to the primary standing member transversely, the measurement frame coupled to the standing frame such that the primary measurement member is substantially parallel to the primary standing member;
a mounting bolster comprising an elongated member, the mounting bolster detachably coupled to the measurement frame such that the mounting bolster is substantially parallel to the primary measurement member;
a crossbar detachably coupled to the mounting bolster; and
a target detachably coupled to the crossbar, the target suitable for a sensor calibration.

### Claim 8 (depends on 7)

The assembled sensor calibration device of claim 7, wherein the mounting bolster comprises a bolster pin retaining the mounting bolster on the measurement frame.

### Claim 9 (depends on 7)

The assembled sensor calibration device of claim 7, wherein the mounting bolster is adjustably coupled to the measurement frame, the adjustment comprising a variable position of the mounting bolster with respect to a longitudinal length of the primary measurement member.

### Claim 10 (depends on 7)

The assembled sensor calibration device of claim 7, wherein the mounting bolster further comprises a support pin supporting the target.

### Claim 11 (depends on 7)

The assembled sensor calibration device of claim 7, wherein the crossbar detachably couples to the mounting bolster using a magnetic coupling.

### Claim 12 (depends on 11)

The assembled sensor calibration device of claim 11, wherein the target is detachably couples to the crossbar using a magnetic coupling.
