Techniques for diagnosing failures in a digital solenoid I/P converter are provided herein. A controller of the I/P converter may apply a fixed voltage to an I/P coil of the I/P converter, causing an armature to move from an off-position to an on-position in a properly-functioning I/P converter. The controller may receive an indication of whether a digital logic line trip has occurred, indicating that a current for the I/P coil has reached a desired maximum current level. The controller may remove the fixed voltage applied to the I/P coil when the maximum current level is reached or when a threshold period of time has elapsed from the application of the fixed voltage to the I/P coil. The controller may diagnose, based on whether the digital logic line trip occurred prior to removing the fixed voltage, a failure in the I/P converter.

Techniques for diagnosing failures in a digital solenoid I/P converter are provided herein. A controller of the I/P converter may apply a fixed voltage to the I/P converter, causing an armature to move from an off-position to an on-position in a properly-functioning I/P converter. The controller may receive an indication of whether a digital logic line trip has occurred, indicating that a current for the I/P coil has reached a desired maximum current level, and an elapsed time from the application of the fixed voltage. The controller may compare the amount of time elapsed from the application of the fixed voltage to an expected amount of elapsed time from the application of the fixed voltage to the I/P coil after which a digital logic line trip will occur for a properly functioning I/P coil and diagnose, based on the comparison, a failure in the I/P converter.

Methods, apparatus, and articles of manufacture are disclosed to control communication data rates of low-energy devices. An example apparatus includes a Bluetooth Low Energy (BLE) radio, and a power manager to determine whether to divide a first computation task into at least a second and a third computation task based on (1) energy stored in a power supply associated with the BLE radio and (2) a charging rate of the power supply, and when the first computation task is to be executed by the BLE radio and the first computation task is divided based on the determination, instruct the BLE radio to enter a sleep mode after the second computation task is executed, and invoke the BLE radio to transition from the sleep mode to an operating mode to execute the third computation task, the invoking in response to a measurement associated with the power supply satisfying an energy threshold.
