Combinatorial test device

摘要

A combinatorial test device is configurable to contemporaneously test one or more sensors of output devices free from user intervention. A device under test such as a user device is placed in a test fixture of the combinatorial test device. Under the control and monitoring of a test controller testing takes place. The testing may be performed for quality assurance after assembly or repair, or to determine the reliability of the device such as by testing the device until a particular life cycle value is reached or a component in the device fails.

1. A device, comprising:
an articulated test fixture comprising:
a frame mechanically coupled to one or more actuators such that the frame rotates upon activation of at least a portion of the one or more actuators;a device mount configured to hold a device under test, the device mount coupled to the frame via one or more mount actuators; and a stimulation fixture arranged opposite to the articulated test fixture, the stimulation fixture comprising:
a stimulation source mount coupled to one or more stimulation source actuators; anda plurality of sensor stimulation sources coupled to the stimulation source mount, at least one of the sensor stimulation sources configured to provide at least one stimulus to one or more sensors of the device under test; and a test controller configured to control the one or more mount actuators to rotate the device mount about an axis and to simultaneously control the one or more stimulation source actuators to rotate at least a portion of the stimulation source mount about the axis such that the device mount and the plurality of sensor stimulation sources coupled to the stimulation source mount simultaneously rotate about the axis.
