Description

IXJ-020 ‘Mono’ device Alignment tool A in CTIA Test Plan

User grip studies indicate that the average grip for this type of EUT has the index finger pressing against the back, the ring finger in contact with the EUT at the bottom, and the pinky finger not touching the EUT. To help maintain a consistent, repeatable positioning that conforms to the grip studies, an alignment tool with evenly spaced rulings is first used to measure the EUT. The EUT is then positioned in accordance with ruled markings on a conformal palm spacer. Alignment Tool ’A’  IXJ-020 features a 120º interior corner to help ensure that the ring finger tip lands in the desired position at the bottom of the EUT, regardless of any curvature in the EUT corners. There are two ruled scales: a bottom ruler (measuring down from the 120º corner) and a side ruler (measuring up from the 120º corner).

IXJ-030 ‘Fold’/ ‘Clam’ devices Alignment tool B in CTIA Test Plan

User grip studies indicate that the average grip for this type of EUT has the index finger pressing against the back of the flip above the hinge, and the thumb and remaining fingers gripping the base below the hinge. To help maintain a consistent, repeatable positioning that conforms to the grip studies, an alignment tool with evenly spaced rulings is first used to measure the EUT. The EUT is then positioned in accordance with ruled markings on a conformal palm spacer. Alignment Tool B IXJ-030 features two rounded humps upon which the EUT is suspended. One hump represents the index fingertip of the hand phantom, while the other represents the palm spacer. This design helps ensure that the index finger remains in contact with the flip for any fold EUT geometry, regardless of hinge position or fold angle. The tool also features a line marking along its side wall, for aligning the EUT hinge axis of rotation for consistent positioning. The ruled scale for measuring the bottom of the EUT is split-level in order to minimize parallax discrepancies when measuring EUTs that are suspended above the ruler by their fold angle.
