摘要:
A response function of a device may be determined using rank minimization to transform a problem of determining a response function of the device into a framework of a rank minimization problem. A function is identified that minimizes a rank of an observation matrix which includes data of observations obtained by the device. This transformation may be used to determine a response function of the device under various conditions and to determine response functions of different devices in a unified framework.
摘要:
A light-emitting device of a portable communication terminal improves exterior decoration by emitting light to the exterior of the portable communication terminal and implements a sense of unity of a design in a non-light emission state by integrating a portion to which the light is transmitted with a main body housing. The light-emitting device includes a housing, a light-emitting element for emitting light, a light guide sheet for guiding the light from the light-emitting element, and a light-transmitting portion integrally formed on the housing for transmitting the light from one end of the light guide sheet to an outer side of the housing. A sense of unity of the main body housing and the light-transmitting portion can be improved by applying a non-conductive vacuum metallizing (NCVM) process to the exterior. An aesthetic sense is improved with the sense of unity of the exterior design.

A method of compensating for an imbalance of a hard disk drive includes biasing a plurality of disks in one direction with respect to a rotational shaft of a spindle motor hub, measuring an amount of imbalance of the plurality of disks with respect to the rotational shaft of the spindle motor hub, and compensating the amount of imbalance of the plurality of disks by hitting the hard disk drive in the opposite direction to the one direction in which the plurality of disks are biased to reduce the amount of imbalance with an amount of impact predetermined based on a measured imbalance amount.
