  • Publication number: 20240110901
    Abstract: The present disclosure relates to devices, circuits, and methods of determining power consumption in an electronic device (e.g., HDD) so that the determined power consumption can be used to determine a concentration of the gaseous oxidizing agent component in an interior gas space of the sealed enclosure and/or actively supply gaseous oxidizing agent component to the interior gas space of the electronic device if the determined power consumption is below a threshold value.

  • Patent number: 7633696
    Abstract: A fly height controller that controls fly height of a read/write head relative to a rotating data storage disk is calibrated. A heater signal is applied to a heater element to heat the head. The level of a write current that is conducted through the head is increased until the head contacts the disk. The fly height controller is calibrated based on at least a first level of the heater signal and a first level of the write current when the head contacts the disk.

  • Publication number: 20020033242
    Abstract: This patent application addresses people's safety when utilizing garage doors. It is aimed at fortifying the safety of garage door utilization. This is accomplished by adding a braking mechanism design onto the garage doors that stops the doors from shutting down when an object or a person or an animal is in its path. It is a mechanical invention and could apply to existing garage doors or introduced into a new door designs.

  • Patent number: 5774285
    Abstract: Method for optimizing parameter values in a read/write channel of a disc drive. A population of error rate points is obtained from selected ranges of a plurality of read/write channel parameters, each error rate point corresponding to a unique combination of parameter values and having an associated error rate value. A weight is determined for each of the error rate points through normalization to the minimum error rate value in the population. A threshold value is determined based upon the error rate values in a plurality of nominally identical disc drives and the weights are compared to the threshold value. Those error rate values having weights less than the threshold are selected and a center of gravity is determined therefrom. At such times that the entire population of error rate values has weights greater than the threshold value, the optimum parameter values are those that map to the center of gravity.
