摘要： A hard disk drive enters a low power mode to reduce power consumption. To maintain communication with a host device, a communication interface remains energized along with a circuit portion storing configuration data for the communication interface. To energize the communication interface and the circuit portion, low power voltage regulators provide suitable reference voltages. One low power voltage regulator is dedicated to this purpose. Another voltage regulator is converted from an active, switching mode to a low power, linear mode to provide the necessary reference voltage. Also, unique handshaking signals are used to control entry and exit from the low power mode by the hard disk drive.

摘要： Compositions and methods for producing compositions comprising a monoamine-endcapped polyimide component. Based on a gas chromatography mass spectroscopy analysis of a surface rinse of the composition performed at room temperature, the composition can have at least one surface with less than or equal to 5 ppb releasable phosphorous residuals, and less than or equal to 5 ppb releasable volatile organic compound residuals. The composition can also comprise less than or equal to 10 ppb combined releasable residuals. Because of the very low levels of residual contamination, the compositions can be used to produce a variety of articles including a disk drive.
