Abstract: A method of testing a part includes placing a first member on a part to be tested. A second member is placed on an opposed surface of the part. One of the members has an ultrasonic transmitter and the other has an ultrasonic receiver. At least one of the members has at least one magnetic element and the other has at least one of a magnetic element or a ferromagnetic metallic element which is attracted to magnets. One of the members moves along the surface of the part such that magnetic attraction causes the other to move along the opposed surface of the part with the one of the members. A controller causes an ultrasonic signal to be sent from the transmitter through the part to be tested which is received by the receiver and then analyzed by an ultrasonic testing machine.

Abstract: Systems, devices, and methods for facilitating diagnosis of sleep respiratory issues and/or delivering therapy for sleep respiratory issues are provided. According to one embodiment, an electronic ear device may be used to provide an effective and more sleep conducive method for positional sleep therapy. For example, positional therapy may be implemented through audible notifications delivered through the ear device to reduce symptoms of positional sleep respiratory issues. A positional sensor within the ear device allows the ear device to recognize when a user of the ear device is out of their programmed sleep position. The sleeper can then be notified through a speaker in the ear device to adjust themselves to a more optimal sleep position for reduced snoring and/or sleep obstruction. The ear device may alternatively or additionally capture user sleep data to facilitate diagnosis of a sleep respiratory issue by a medical professional.

Abstract: A method of extracting essential oil from plant matter for personal use includes positioning an amount of medicinal herb in a mini oven. A heating element is at least partially covered by a metallic heat exchanger and positioned in the mini oven. The medicinal herb is pyrolysized by energizing the heating element. Vaporized essential oil from the medicinal herb is moved out of the mini oven and toward the user. Oxygen is displaced from the mini oven responsive to decarboxylation of the medicinal herb, to inhibit combustion at elevated temperatures.

Abstract: The invention is generally directed to a slider that is particularly suited for dynamic load/unload disk drive designs. This slider desirably addresses potential disk damage associated with contact between sharp edges of the slider of the disk drive and the data storage surface of a corresponding disk.

Further, a read element is provided that includes a magnetoresistive element that, when reading perpendicularly-recorded magnetic transitions from the surface of the magnetic media, produces a readback pulse signal having a substantially Lorentzian pulse shape.

Abstract: A disk drive utilizes a unique write condition for each of the transducers within the drive. Each write condition is determined based upon the specific properties of the corresponding transducer. The write condition information is preferably stored within a memory within the disk drive. When a write operation is performed, the appropriate write condition for the corresponding transducer is used to determine when to write data to the disk. A write condition will typically include one or more individual write criteria. For example, a write condition can specify a write threshold value to be used during a write operation. A write fault threshold value is selected for each transducer by determining a position error distribution corresponding to that transducer wherein the position error distribution is essentially a function of random noise associated with the disk drive, and by using that distribution to determine allowable off-track threshold value (WFL), will protect the drive from encroachments.

Abstract: A disk drive utilizes a track dependent variable write fault gate for each of the transducers within the drive. By deriving a 3 sigma distribution across the repeatable run out (RRO) and the non-repeatable run out (NRRO), a position error signal (PES) is derived which varies in magnitude across the stroke of the transducers and which has a slope used to derive variable write fault gate thresholds for the tracks associated with each transducer. As the stroke of the transducer moves from the outer diameter (OD) to the inner diameter (ID), the magnitude of the write fault gate thresholds may be decreased relative to the PES, and track density and capacity may increase where PES and write fault gate thresholds are low. The invention thus maintains a constant hard error recovery margin across the stroke.

Abstract: A turbine acceleration control system for a transmission in a vehicle determines a desired turbine acceleration based on a downshift type and an altitude of the vehicle. The turbine acceleration control system determines a downshift type that results from one of a throttle increase, a manual downshift, or vehicle deceleration. An altitude model determines an altitude of the vehicle. A vehicle controller communicates with one or more lookup tables to determine the desired turbine acceleration based on the downshift type and the altitude. Additionally, current turbine speed and torque converter slip are considered by the controller in determining the desired turbine acceleration.

Abstract: Adaptive channel optimization in a disk drive is achieved by selecting a track of the recording medium and then writing a first data pattern to opposite sides of the selected track. The first data pattern is written a certain percentage off-track in relation to the centerline of the selected track. A second data pattern is then written directly on the selected data track and the off-track margin is determined as a function of how far the recording head can be positioned away from the center of the selected track during reading of the second data pattern while meeting a specified error rate. The off-track margin test is repeated iteratively using a combination of channel variable settings in order to find a set of variable settings which provides an optimal performance criterion for the drive.

Abstract: The present invention relates to circuitry for processing an analog read signal, such as a signal produced by a magnetoresistive head, in a magnetic data storage system. The circuitry processes the analog signal before the signal reaches the detector which converts the analog signal into a digital signal representative of the data originally stored on the magnetic medium. In one embodiment, the invention comprises circuitry for equalizing the amplitudes of the positive and negative pulses in the analog read signal. In another embodiment, the invention comprises circuitry for reducing the baseline shift of the analog read signal. The invention may be used in magnetic data storage systems using any conventional data detection method.
