摘要： A method for controlling a programmable source of a plurality of string of clock signals, a program is stored with a plurality of different indications of desired frequencies, each indication corresponding to one of the strings of clock signals. The frequency of each of a plurality of oscillator is controlled by the memory content of a separate memory for each oscillator. The content of each memory is adjusted in accordance with the actual frequency of each string, the frequency indicated by the corresponding indication of a desired frequency and a reference.

摘要： A switchable termination module for use with addressable devices on a communication bus has a terminator for each signal transmission path, a signal source, for example a switch for signalling whether termination is desired and a terminator control circuit for engaging and disengaging the terminators in response to the signal from the signal source. The control circuit has a transistor between the source of potential and the terminators to couple the terminators to the transmission paths when termination is desired. The switch which signals whether termination is desired may also be used to select the address for the device.

摘要： A data storage device (DSD) is disclosed comprising a non-volatile memory (NVM), such as a disk or non-volatile semiconductor memory, and control circuitry for detecting a power failure condition. A frequency range of a supply voltage from a first frequency to a second frequency is extracted, wherein the first frequency is greater than ten hertz, the second frequency is higher than the first frequency, and the second frequency is less than one megahertz. The power failure condition is detected in response to the extracted frequency range of the supply voltage.

摘要： A disk drive that includes a base, a magnetic disk, a rotary actuator that carries a head for reading and writing data from the disk in a track-following mode under the control of a servo control system, and at least two sensors—one fixed sensor rigidly coupled to the overall disk drive and one mobile sensor mounted to the rotating actuator—for differentially detecting accelerations of the rotary actuator relative to the overall disk drive and its disk. The disk drive detects and actively compensates for accelerations imparted to a balanced actuator that has an effective imbalance. The fixed sensor is preferably mounted to a PCBA that is secured to the base. The mobile sensor is preferably mounted to an actuator arm of the rotary actuator, as far outboard as possible, and so as to align with the fixed sensor as the rotary actuator swings through its range of travel. The preferred sensors are linear accelerometers.

摘要： A disk drive includes a head disk assembly having a housing including a first surface area, and a strain transducer for producing a strain signal representing strain in the first surface area due to a mechanical shock on the disk drive. The strain transducer includes a first electrode, a second electrode, and a volume of piezosensitive material defining a second surface area. The piezosensitive material is disposed between the first electrode and the second electrode. The first surface area overlaps the second surface area. The strain transducer further includes means for securing the first electrode and the piezosensitive material to the first surface area such that the strain in the first surface area is replicated in the piezosensitive material. The disk drive includes means responsive to the strain signal for controlling a write operation in the disk drive.

摘要： An apparatus and automated process to improve the accuracy and reduce the time, cost, and effort necessary to prepare reproduction artwork for charts is disclosed. A numerically or computer controlled imaging system is used to expose photographic film or emulsion with specially prepared halftone pattern symbols. This allows a computer to be used to select both the symbol and location, instead of slow and costly manual methods. Greatest benefits accrue when the final chart is to be in color. One sheet of film per primary color is exposed using a few basic symbols, which are then combined to yield a wide range of color in the symbols of the final chart. Typically, the final product of this process is one or more sheets of monochromatic film used as masters for a color printing or color key process. Further, a method is described to avoid erroneous density (and resultant color) changes where halftone symbols overlap, as well as various other methods to improve legibility and produceability of the charts.
