  • Publication number: 20190166754
    Abstract: A multiple variety planter is provided that has a direct vacuum system that allows for planting multiple varieties of seed while reducing occurrences of mis-planting events or planting inconsistencies such as multiples and skips by providing highly controllable seed meter vacuum performance characteristics that are controllable on a row-by-row basis. The direct vacuum system may include a vacuum unit at each row unit of the planter to apply a vacuum pressure to a seed meter at the row unit. Each vacuum unit may be individually and variably controlled to apply different vacuum pressures based on which seed variety is being planted with the respective seed meter at a given time.

  • Patent number: 8810952
    Abstract: A head transducer, configured to interact with a magnetic recording medium, includes a first sensor having a temperature coefficient of resistance (TCR) and configured to produce a first sensor signal, and a second sensor having a TCR and configured to produce a second sensor signal. One of the first and second sensors is situated at or near a close point of the head transducer in relation to the magnetic recording medium, and the other of the first and second sensors spaced away from the close point. Circuitry is configured to combine the first and second sensor signals and produce a combined sensor signal indicative of one or both of a change in head-medium spacing and head-medium contact. Each of the sensors may have a TCR with the same sign (positive or negative) or each sensor may have a TCR with a different sign.

  • Patent number: 8730611
    Abstract: A method of detecting a contact between a transducing head and a storage medium is provided. The method applies an input signal, having a select power level and known frequency, to an actuator for actuating the head. An output signal is obtained in response to the input signal. At least one signal component is extracted from the output signal at the same or a harmonic of the same known frequency as the input signal applied to the actuator. Whether the at least one extracted signal component indicates a contact between the head and the medium is determined. The power level of the applied wave pattern is increased incrementally until the extracted signal component indicates a contact between the head and the storage medium.

  • Patent number: 8098455
    Abstract: A magnetic device includes a write element having a write element tip and a conductive coil for carrying a current to induce a first field from the write element. A conductor proximate the write element tip carries the current to generate a second field that augments the first field. A driver provides the current to the conductive coil and the conductor, and a circuit phase shifts the current through the conductor relative to the current through the conductive coil.
