Abstract: A method of ejecting a plurality of samples from a well plate includes receiving a first sample intensity prediction associated with a first sample in a first well of the well plate. A second sample intensity prediction associated with a second sample in a second well is also received. The second sample intensity prediction is less than the first sample intensity prediction. An ejection time delay value for a subsequent analysis of the first sample and the second sample is determined, based at least in part on the second sample intensity prediction. Thereafter, the first sample is acoustically ejected from the first well, and the second sample is acoustically ejected from the second well.

Abstract: A print driver store is usable for redirection printing in a virtualized computing environment that supports virtual desktops. Native print drivers are uploaded to the print driver store from a client side. When an agent attempts to instantiate a virtual printer at the agent side that corresponds to a physical printer at the client side, the agent checks to determine if a native print driver for the physical printer is installed at the agent side. If the native print driver is not installed, then the agent obtains the native print driver from the print driver store and installs the native print driver at the agent side. The agent completes the instantiation of the virtual printer at the agent side and associates the native print driver with the virtual printer.

Abstract: A method and a system for diagnosing a fault of a three-phase three-level rectifier are relate to the technical field of fault diagnosis of power electronic equipment, and provided to implement identification and location of an open-circuit fault of a power switching device thereof. A deviation between an expected value and an actual value of a phase-to-phase voltage is adopted as a diagnosis variable. The diagnosis variable is calculated by adopting a screening technique, thereby reducing calculation error to ensure accuracy of diagnosis. Only existing voltage current signals in a control system of the rectifier are required to calculate the diagnosis variable, so no additional hardware is required and low-cost fault diagnosis can be implemented. Different voltage thresholds are adopted for different fault characteristic sections, and the voltage thresholds are updated in real time according to a direct current side voltage, which improves diagnosis speed while ensuring higher robustness.

Abstract: An automatic compensation method based on temperature characteristics of RGB LEDs by first obtaining current temperatures of the RGB LEDs, and then adjusting a corresponding PWM duty cycle of each LED according to the current temperature of each LED to change drive currents of the RGB LEDs, thereby achieving compensation for the RGB LEDs. By determining a temperature adjustment coefficient of each LED based on the current temperature, temperature adjustment ratios, and an adjustment step size of the LED, and finally adjusting the PWM value according to the temperature adjustment coefficient to drive the LED, color shift is reduced. When performing PWM duty cycle adjustment, adjustment formulae are used, which only require obtaining the current temperature, the temperature adjustment ratios, and the adjustment step size of each LED, and then calculating according to the formula, therefore not requiring extensive data storage or data lookup and thus resulting in lesser computation.

Abstract: Example methods and systems to implement an economic printing mode are described. In one example, a computer system may provide a user interface specifying multiple selectable levels associated with economic printing mode. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content. For example, in response to a selection of a first level, print quality may be reduced. In response to a selection of a second level, image information in the source printing content may be modified. In response to a selection of a third level, font information associated with textual information in the source printing content may be modified. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.
