摘要： Disclosed are methods and apparatus for digital control of a head-disk assembly actuator with dynamic velocity compensation. In preferred methods of the invention steps are disclosed in which, the actuator voltage in an HDA is sampled and a velocity error is determined. The voltage applied to the actuator is compensated for the velocity error. Disclosed methods of the invention also include steps for measuring the actual voltage at the actuator motor and alternatively, for calculating the actuator motor voltage using digital processing techniques. A digital voltage command is then provided for applying compensated voltage to the actuator motor. Apparatus for implementing the methods of the invention in a hard drive assembly having an actuator motor is also described. The apparatus includes a sampler for sampling an actuator motor voltage, a timer, and a digital processing engine for receiving a target actuator voltage command and the digital actuator motor voltage sample and for outputting a digital voltage command for controlling the actuator motor.

摘要： An MRI method and an MRI system that simultaneously detect blood and/or CSF velocity or flow in plural slices or slabs preferably as not spatially adjacent. Two or more sets of interleaved slices or slabs can be assembled to cover the desired volume and derive higher quality MRI signals and images without a need for a contrast agent, even where the volume is too large for effective flow imaging with known techniques without contrast agent.

摘要： Systems, methods, and computer storage mediums are provided for incentivizing users to contribute content in a controlled manner. A method includes receiving content and metadata associated with the content from a user. The content relates to a geolocation and the metadata includes geolocation information that relates to the content. It is then determined whether the content and the associated metadata meet a threshold of specific criteria. The specific criteria is based on a set of rules that determines an amount of points awarded to the user for providing content that satisfies the specific criteria. The specific criteria include at least a geolocation or geolocated area. If the content meets the threshold of the specific criteria, points are awarded to the user. The amount of points is based on a comparison of the content and the associated metadata with the specific criteria.

摘要： Methods and apparatus to lock a phase lock loop to a spindle motor are disclosed. An example controller comprises a counter to determine a period of an operating signal received from a motor, an oscillator to generate a control signal based on an input signal, and an initializer to generate the input value based on the period, wherein the input value causes the oscillator to generate the control signal having the same phase as the operating signal.
