摘要： A liquid dispensing apparatus for dispensing droplets of a liquid, and methods for measuring various fluid parameters of the liquid are described. The liquid dispensing apparatus comprises a container having a chamber for holding a liquid. An orifice is positioned at an end of the chamber for dispensing droplets of the liquid, the orifice being configured to retain the liquid in the container if the container is positioned with the orifice facing in a downward direction. An acoustic transducer means is at least partially positioned in the chamber for periodically propagating a focused acoustic beam toward the orifice and through at least some of the liquid while the liquid is contained in the chamber, with the focused acoustic beam being capable of causing a droplet of the liquid to be ejected from the orifice when a free surface of the liquid is within the depth of field of the acoustic transducer means. Fluid parameters that can be measured include the sound velocity in the liquid, liquid level and liquid concentration, liquid acoustic impedance, liquid density ultrasonic attenuation and ultrasonic viscosity.

摘要： Magnetic noise cancellation in a single-ended MR preamplifier front end is achieved by forming a balanced ground return path in a flex circuit connecting an MR head to the front end of the preamplifier. The balanced ground return path introduces a noise current in the opposite direction of the original noise current as viewed at the signal input pins of the preamplifier chip. In this manner common mode rejection of the radiated noise component is restored in the single-ended MR preamplifier circuit arrangement.

摘要： A "zero phase start" optimization circuit for a Partial Response, Maximum Likelihood ("PRML") data channel dynamically determines a more optimal starting phase for the timing recovery process in a synchronous communication or storage system. The disclosed circuit includes a quantizer, a summing junction, either an absolute value or squaring function, and an integrator. A firmware based optimization routine causes a timing control loop to go through a series of timing acquisition modes, each time starting a clocking oscillator at different phase. The optimization circuit calculates the mean squared error between actual and expected sample values from a known frequency preamble pattern for each timing acquisition. The minimum MSE value corresponds to a more optimal starting phase for the timing control loop oscillator.

摘要： A diskette comprising a jacket, a liner material disposed within said jacket, a flat circular media having a magnetic coating on both sides disposed within said liner material, a hub attached at the center of said media, a plurality of servo grooves on at least one of said sides of said media that have stitched patterns that will alternate on-and-off at twenty kilohertz in the presence of a constant, unmodulated light source. The diskette is magnetically formatted with reference and data tracks recorded in such a way that extremely accurate position determinations can be made by looking at the analog amplitude of the detected tracks and comparing them at different head positions. The innermost tracks contain redundant copies of a disk mapping table that comprises data for a media type code, a sector size code, a sector interleave code, a total track count, a reassignment area starting address, a data area starting address, a total sector count, an update count, and a reassignment table having at least room for 250 entries of three bytes each.
