Abstract: A device having an integrated circuit that includes a relative humidity sensor as well as a memory element for storing calibration information for the relative humidity sensor. Because of the nature of fabrication of an integrated circuit for a relative humidity sensor, variances in the creation of electronic components therein may lead to a need to calibrate the sensor after assembly. Such calibration information may be ascertained at the time of fabrication and stored in a memory component disposed on the integrated circuit chip. By storing the calibration information, which may be determined at the time of fabrication, one does not need to determine such calibration information later at assembly or store the already determined calibration information in a remote location until assembly if it was, in fact, ascertained at fabrication. Then, at assembly, one needs only to read the calibration information in order to calibrate the relative humidity sensor.

Abstract: An embodiment of a circuit for maintaining voltage at a voltage bus after a power loss in a hard disk drive system. HDD systems may suddenly lose power and specific tasks, such as parking the read/write head and storing state data may be accomplished using a power generated from back EMF of a motor that is still turning. During the power loss sequence, a drive controller may drive a power chipset to regulate the voltage at a voltage bus so as to conserve power as much as possible. In this manner, the drive circuit may regulate the voltage via a drive algorithm to be just above a threshold voltage (typically 4.4 V) while the HDD system is storing state data, but apply other algorithm for other situations, such as parking the read/write head. Various drive algorithms may be tailored to provide a specific sequence of voltage bus regulation techniques suited to specific applications.
