摘要： A method and apparatus for data disks adapted to compensate for effects of shock loads imparted to a disk drive which are of sufficient magnitude to cause disk shifts. A series of topographical features are formed on the disk surface or edge to cause signal fluctuation in a sensor during read-back mode operation. An initial signal profile is stored as a map indicative of track or disk alignment with respect to the actuator assembly. Selectively, such as after a known shock event, the topographical features are re-profiled. A comparison of the profiles provides a measure of any track distortion which must be compensated for in future read-write operations by adjustments to data track servo follower algorithms.

摘要： An improved glide head has an air bearing surface with a flatness of less than about 1 μinch. The air bearing surfaces are formed from the very smooth and flat surface of a wafer, preferably prior to slicing the glide heads from the wafer. Thus, a wafer is formed having a flat surface with a plurality of air bearing surface contoured onto the surface. To form a glide head, a transducer can be mounted on the air bearing surface or the surface opposite the air bearing surface, preferably at the wafer level before slicing.

摘要： A system and method are disclosed for reducing reverse bias in an electrophoretic display. The system and method include the application of varying levels of voltages across an array of electrophoretic display cells of the electrophoretic display to move the cells towards a stable state in a driving cycle. In addition, the system and method disconnect the voltages from the electrophoretic display cells at a time duration prior to reaching step transitions of the voltages during the driving cycle. Pre-driving approaches apply a first pre-driving voltage at a first polarity to the display cells before driving the display cells with a second driving voltage at a second, opposite polarity. Varying the time duration and amplitude of the pre-driving signals produces further beneficial reduction in reverse bias.

摘要： Electronic devices such as computers and handheld devices are provided. The electronic devices may have electrical components such as displays that are driven by driver circuitry. During operation, the driver circuitry may generate radio-frequency noise. Communications circuitry in the electronic devices may be shielded from the radio-frequency noise by radio-frequency shielding structures. The shielding structures may be mounted on portions of the display module, on a cover glass layer, or on other structures such as housing structures. The radio-frequency shielding structures may be formed from one or more metal segments. The metal segments may run along edges of the display. A device housing may have a ground formed from a conductive peripheral member that runs around peripheral edges of the housing and a conductive plate that is connected to the conductive peripheral member. The radio-frequency shielding structure may be connected to the ground using conductive structures.

摘要： A pulse-width modulated backlight control for a video display restarts the pulse-width modulated pulse train on occurrence of a video refresh pulse. In order to prevent an undesirable momentary increase in brightness in the event that the last pulse of the pre-refresh pulse train occurs too close to the first pulse of the post-refresh pulse train relative to the normal pulse interval, the width of the first pulse following refresh may be reduced from a first value determined by the desired brightness to a second value that bears the same proportion to the first value that the interval between the beginning of the previous pulse and the occurrence of the refresh pulse bore to the normal pulse interval. In that way, the duty cycle during the shortened pulse interval is the same as during a normal pulse interval, avoiding or minimizing perceptible increase in backlight brightness.
