摘要： A disk drive includes a rotatable data storage disk, an interface, a transducer, a write buffer, an actuator, and a controller. The transducer is configured to read and write data on the disk. The interface is configured to receive data with associated write commands and a park signal. The write buffer is configured to temporarily store the data and associated write commands while the data waits to be written on the disk via the transducer. The actuator is configured to move the transducer between a parked position and tracks on a disk where data is read and written. The controller is configured to execute the buffered write commands by positioning the transducer relative to tracks on the disk while writing data from the write buffer to the disk, and is configured to respond to the park signal, which is indicative of an imminent transducer to disk contact condition, by moving the transducer to the park position without completing execution of the buffered write commands.

摘要： A method and apparatus which can provide a temperature estimate in a hard disk drive or other electronic device is provided. Output from the sensor, which may be indicative of a location spaced from the target temperature location, is sampled and integrated over an interval of time to form an estimate of average input sensor voltage. During the time interval, history of the HDD pre-amplifier operating modes is accumulated. The results are combined to form an estimate of HDA ambient temperature. Sensor offsets associated with each power mode, and weighted to the corresponding mode duty, can be subtracted from the average input sensor voltage.

摘要： The invention is a detection and prevention system to detect and prevent fluid leaks in a property that may cause damage to the property. The sources of the leaks may include, for example, toilets, hot water heater, sinks, washing machines, water makers and broken pipes or other sources of fluid leaks. The inventive may include one or more sender units that may be positioned at various locations on a property. The sender units may have a fluid sensor (for detecting a fluid leak) and a transmitter (for communicating with a base unit). The base unit may receive signals from the transmitter when the fluid sensors detect a fluid. The base unit may then communicate with a main shut off valve to restrict the flow of fluids onto the property.

摘要： An information storage device comprises a media including a ferroelectric layer and a conductive layer and a cantilever adapted to be actuated toward the media. A tip extends from the cantilever and an electrode associated with the cantilever. When the cantilever is actuated, the tip applies a contact force to strain the media so that a charge is coupled from the ferroelectric layer to the tip. A signal is applied to the electrode to generate electrostatic force between the electrode and the conductive layer, causing the cantilever to vibrate based on a frequency of the signal. Vibration of the cantilever causes the contact force applied by the tip to the media to vary. Polarization of the ferroelectric layer can be determined based on one or both of a baseband signal generated by the charge accumulated at the tip and an upper-band signal generated by the variation in phase of the charge accumulated at the tip.
