A means and method for arbitrarily coordinating a tactile vibratory stimulus with an audio stimulus. There is provided an adult-type sex toy, and associated method, with a vibrator and audio player in which the audio player is augmented with additional circuitry and firmware, such that the audio player is in signal communication with the vibrator to to control the speed of the vibrator motor. The motor speed, however, is not correlated with raw audio signal strength or frequency. Rather, the vibrator motor speed is regulated by motor speed information embedded with the audio file being played back. Accordingly, the apparatus audio player can play back an erotic story, for example, while automatically coordinating the vibrator motor speed in concert with the perceived content of the audible story as heard by the user-listener.

Vibrator apparatus with audio and motor control features

A hard disk drive, its use and production are described. A read/write disk stores digital data. A spindle motor supports the read/write disk for controlled rotation thereof. A head arrangement moves to selectively access the read/write disk in a data access mode and moves to a parked position. A dedicated input is receives a first sensor related input signal. A processing arrangement executes the data access mode by cooperatively controlling the spindle motor and the head arrangement, monitoring the sensor related input signal for a predetermined characteristic thereof, and responsive to detection of the characteristic, at least moves the head arrangement to the parked position. A hard disk drive multi-sensor group, monitoring technique and interface are described.

Hard disk drive with external sensor interface, system for use thereof and method

A computerized system is described (i) which includes an interface connected with a peripheral device and (ii) which is incapable of dynamically extending bus cycle timing if required by the peripheral device to carry out a particular current operation. This computerized system includes a given peripheral device which, during normal operation of the device, can require an extension of bus cycle timing to carry out the current operation. This device generates a specific signal when the extension is required. The device is connected with the interface of the computerized system and the system is configured to cause the system (i) to recognize the specific signal and (ii) to instruct the peripheral device to retry the current operation responsive to the specific signal. In a particular embodiment, the peripheral device is a disk drive having an ATA interface and the specific signal generated by the disk drive is an IORDY signal.

Peripheral device in a computerized system and method

An electromechanical data storage arrangement is interfaced with a host. The interface may include a conductor that carries read and write gate signals. Another conductor carries both a servo sync mark and an error signal. The storage arrangement includes an external serial interface connected to a host serial interface applying a device identification to a portion of serial control-related data that travels over the interface. A serial router in the storage arrangement uses the device identification to manage the control-related data between the interface and a number of serial devices and associated interfaces within the storage arrangement. The serial router is in selective data communication with each of the device serial interfaces, for using the device identification to direct a host-asserted command to a targeted device where each device is controlled by a different command set such that the system can be customized for different command sets of different devices.

Digital device configuration and method

The present invention relates to a system for determining whether the flying height of a read/write head above a disk in a disk drive is within an acceptable range, in substantially real time. The system relies on variations in read signal resolution with flying height to make the determination. In one embodiment, read signal resolution is measured and compared to a predetermined threshold value to determine whether the present flying height is in the desired range. In another embodiment, the number of peaks in a read signal that are detected (and/or not detected) by a detector is used to determine whether the head is in the proper flying height range. Because of read signal resolution effects, the number of detected peaks will decrease as the flying height of the head is increased. Means are also provided for postponing a transfer of data to/from the disk when it is determined that the head is not within the acceptable range.

Disk drive which detects head flying height using first and second non-overlapping data patterns with different frequencies

A disk drive system corrects run-out errors without substantial PES transients and without significant response time. The disk drive system includes a servo compensation system coupled to a read/write head. The servo compensation system is adapted to generate a run-out correction waveform for a track in a disk. The run-out correction waveform includes one or more sinusoidal component waveforms, each of which is defined by a phase and an amplitude. The method includes measuring an amplitude and a phase of one or more sinusoidal component waveforms for a set of specified tracks in a disk. The method also includes determining a phase and an amplitude of one or more sinusoidal component waveforms for a destination track based on a measured amplitude and a measured phase of the one or more measured sinusoidal component waveforms. The sinusoidal component waveforms for the destination track are adapted to substantially correct a run-out error in the destination track. The method further includes generating a run-out correction waveform for the destination track such that the disk drive system substantially corrects the run-out error in the destination track.

Disk drive which detects head flying height using a peak count based on a data pattern

The invention is a servo compensation method and system for use in a disk storage system. The disk storage system experiences error that causes a head to become mis-aligned with the disk. The error comprises multiple spin-frequency harmonic run-out error and other servo position errors. During follow mode, a digital filter processes a position error signal to generate a compensation signal. The position error signal is comprised of components representative of the multiple spin-frequency harmonic run-out error and the other servo position errors. The compensation signal is comprised of components that cause the servo positioning system to compensate for the multiple spin-frequency harmonic run-out error and the other servo position errors. The digital filter also operates as an oscillator that provides an oscillating signal at multiples of the spin frequency of the disk during seek mode.

Disk storage system servo compensation for run-out error

An invention for more accurately initiating the generation of detection windows for detecting data within a stream of data pulses is disclosed. A high frequency clock, typically operating at rate corresponding to a multiple of the nominal clock rate (e.g., two or three times, is used for a portion of a decoder system. In one embodiment, a down counter and a detection window generation component of the decoder system are clocked at the higher rate, while the remaining elements are clocked at the nominal clock rate. In this manner, the detection windows are more accurately initiated, while the remaining portions of the decoder system do not require the extra expense imposed of operating at the higher clock rate. Using the present invention, synchronization delay is minimized and detection windows are more accurately aligned with data pulses which reduces the error rate and improves performance of the decoder system.
