摘要： Determining a contact condition between read-write head and accessed disk surface inside hard disk drive, where micro-actuator assembly mechanically couples to slider and electrically interacts through signal path. Signal path sensed, creating sensed feedback signal, used to determine contact condition, which indicates when read-write head is, or is not, in contact with accessed disk surface. Means for implementing this process. Contact condition is product of process. The process may respond to contact condition, altering read-write head flying height. Process may be implemented as operations of embedded control system and/or servo controller. Method of predictive failure analysis using the contact condition to estimate performance parameter and create performance degradation warning. Manufacture process collecting contact condition to partly create reliability estimate of the hard disk drive, which may be form of Mean Time to Failure. Manufacturing may further include screening the hard disk drive based upon the reliability estimate.

摘要： In general, the invention is directed to systems and techniques for assessing a risk of ventricular tachyarrhythmia in a patient by measuring one or more biochemical markers that reflect the health of a patient. Typically, the patient submits a sample, such as a blood sample, which is tested for one or more biomarkers. Based upon the results of the tests, the patient's risk of ventricular tachyarrhythmia may be assessed. When the patient is found to be at risk, the patient may receive an implantable medical device or drug therapy to address the risk.

摘要： The present invention provides an efficient method for bypassing outputs while in redundant form to an arithmetic circuit that is capable of adding or subtracting numbers in redundant from and comparing the magnitudes of numbers received in redundant form for equality and inequality relationships. For one embodiment of the invention, an arithmetic circuit subtracts numbers received in redundant form and compares the result to zero represented in redundant form without carry propagation. In parallel with the subtraction and comparison, the most significant bits of each number received in redundant form are generated and compared for equality, and a carry-out is generated for the subtraction. These results are combined by magnitude comparison logic to produce a magnitude comparison for the numbers received in redundant form.

摘要： A system and method for delivering both anti-tachy pacing (ATP) therapy and high-voltage shock therapy in response to detection of abnormal cardiac rhythms is disclosed. The system controls the time between delivering ATP therapy and the charging of high-voltage capacitors in preparation for shock delivery based on a predetermined set of criteria. In one embodiment, the inventive system operates in an ATP During Capacitor Charging (ATP-DCC) mode wherein all, or substantially all, of the ATP therapy is delivered during charging of the high-voltage capacitors. Based on evaluation of the predetermined set of criteria, the system may switch to an additional ATP Before Capacitor Charging (ATP-BCC) mode, wherein substantially all of the ATP therapy is delivered prior to charging of the high-voltage capacitor. According to one aspect of the invention, the predetermined set of criteria is based, at least in part, on the effectiveness of previously-delivered ATP therapy.

摘要： An environmental chamber that can be used to test a device under test such as a hard disk drive. The environmental chamber may include an electronically controlled shutter that controls the flow of controlled particles from a second chamber to a first chamber. The controlled particles flow to a device under the test located within the first chamber. The shutter can be closed when a predetermined threshold of contaminants is detected by the environmental chamber. This two-chamber method provides a stable and uniform density of particle environment around the drive.
