    摘要: Various illustrative aspects are directed to a data storage device comprising one or more disks; a spindle motor for rotating the one or more disks, wherein the spindle motor comprises a plurality of magnetic pole-pairs, and wherein the spindle motor is configured to operate in a plurality of modes, including at least a first mode and a second mode; and one or more processing devices configured to select a reference point for spindle motor interrupt service routines (ISRs), determine a delay time, wherein the delay time is based at least in part on a number of magnetic pole-pairs and a mechanical revolution period of the spindle motor, start a timer at a first ISR, and when the timer is equal to the delay time, switch operation of the spindle motor from the first mode to the second mode.

    摘要: Inductively coupled plasma (ICP) RF power delivery systems are disclosed that include at least two ICP coils. At least one of the ICP coils is directly driven by an RF resonant power amplifier that includes a resonant tank comprising the ICP coil. A controller is configured to control the power into the direct driven ICP coil by varying a corresponding DC voltage source and simultaneously varying operating frequency into the ICP coil by allowing a resonant voltage waveform across a corresponding open switch network to rise and then fall to substantially zero volts before closing the corresponding switch network for a remainder of an RF cycle. Some variations comprise at least one passive ICP coil that is arranged and configured to be inductively coupled to the first ICP coil, and the passive ICP coil is terminated by an independently adjustable impedance.

    摘要: Systems, methods, and apparatuses for measuring capacitance of a load. An apparatus includes a ground connector, an output connector configured to couple to the load, and a time-varying signal source configured to inject a time-varying voltage signal onto a conduction path between the ground connector and the output connector. A DC power source is configured to apply a DC offset to the time-varying voltage signal, and a current monitor is configured to measure time-varying current in the conduction path. A capacitance module is configured to determine the capacitance based upon at least one of the time-varying current and a frequency of the time-varying voltage signal.

    摘要: Systems, methods, computing platforms, and storage media for dynamically organizing autonomous storage units in a retail control territory are disclosed. Exemplary implementations may identify a plurality of autonomous storage units, wherein each autonomous storage unit is configured to hold one or more inventory items; identify an inventory level for each of the plurality of autonomous storage units; determine a first arrangement for the plurality of autonomous storage units based in part on one or more first factors; organize the plurality of storage units in the first arrangement; identify one or more second factors; determine a second arrangement for at least a portion of the plurality of autonomous storage units based on the one or more second factors; and direct the at least the portion of the plurality of autonomous storage units to organize in the second arrangement.
