Abstract: Systems and methods presented herein provide for operating an optical network terminal (ONT) during a power outage. In one embodiment, an ONT includes an opto-electrical converter operable to receive an optical signal and to convert the optical signal to a data signal, and a data processing module operable to process data from the data signal. The ONT also includes a power management unit operable to detect a power outage of a power supply, to initiate a low power mode, to terminate a portion of data processing by the data processing module based on the low power mode, to convert the optical signal to electrical power, and to maintain operation of the low power mode utilizing the electrical power. The power management unit is further operable to monitor the power supply for restoration of power, and to reinitialize the data processing module upon restoration of power.

Abstract: The effects of an air bearing may be augmented in various ways in order to assist in the automated assembly of valve spools into valve bores. Such augmentation may be achieved by agitating one end of the valve spool with sequentially applied pulses of pressurized air as the spool is being lowered into the valve body, increasing the effective length of the valve spool so that the agitation can be applied to the spool when the spool is partially inserted into the body, varying the position of the valve spool while the spool is being inserted into the valve body to expose a length of the spool to the pulses of pressurized air, and applying an oscillating vibration to the fixture that supports the valve body to dislodge a spool that has become jammed in the valve bore.
