A bending test fixture for test coupons includes a test region for receiving a test coupon and first and second supports on opposed sides of the test region. The actuator includes a sensor and a control circuitry, which includes a controller connected to the actuator. Additionally, conducting further computing system operations can include restoring the saved first portion of registers from the memory location to the registers and resuming execution of the first thread. The detected modulation characteristics are typically determined based upon a measured signal level, e. This ensures venting of the volume of the container with a relatively weak torque.
