A system, method, and computer-readable medium are disclosed automatic validation of light emitting diodes (LEDs) of disk drives in disk processor enclosures (DPEs) or disk array enclosures (DAEs) during the manufacturing and integration of computer systems. An automated test script is performed in support of the integration of the computer system that includes the LEDs and includes a validation and checking step for the LEDs. A determination is made if a camera is properly calibrated to identify the LEDs as part of the validating and checking step for the LEDs. A DPE or DAE that contains disk drive units that include the LEDs are identified, and an indication is performed as to which LEDs pass or fail.

A magnetic disk drive includes first and second disks having respective first and second surfaces, a first head including a first write head that writes data on the first surface at a first recording density, and a first assist element that generates a first energy for increasing a write performance by the first write head, a second head including a second write head that writes data on the second surface at a second recording density, and a second assist element that generates a second energy for increasing a write performance by the second write head, and a controller that changes one of the first and second recording densities based on a first recording capacity up to which the first head is capable of writing on the first disk, a second recording capacity up to which the second head is capable of writing on the second disk, and a target capacity.

A card reader is provided which is capable of detecting a skimming magnetic head attached to a front side of a card insertion member formed with a card insertion port and a skimming magnetic head attached to an inclined face of the card insertion port with a simple structure. The card reader includes a card insertion member 8 formed with a card insertion port 3 and a light emitting element 9 and a light receiving element for detecting that a foreign matter has been attached to the card insertion member 8. A lower face of the card insertion port 3 is formed to be an inclined face 3a which is inclined toward a lower side as going to the front side.

The present invention relates to a method and apparatus for visualizing information of a digital video stream is disclosed. The apparatus comprises: a memory arranged to store a series of merged image frames which is formed by merging groups of image frames of the digital video stream; a blending module arranged to blend multiple merged frames into a series of blended image frames, wherein each of a plurality of the merged image frames contributes to a plurality of the blended image frames; and a display arranged to display the series of blended image frames.

A shack-sensor apparatus may include a sensor configured to detect a positional state of a hard-drive drawer. The shock-sensor apparatus may also include a mounting component coupled to the sensor and configured to mount the sensor in a location to monitor the positional state of the hard-drive drawer. In addition, the shock-sensor apparatus may include a computing module, electronically coupled to the sensor, that analyzes sensor data provided by the sensor to predict a shock event of the hard-drive drawer and send, in response to predicting the shock event, a signal to at least one hard drive in the hard-drive drawer to prevent damage to the hard drive. Various other apparatuses, systems, and methods are also disclosed.
