  • Patent number: 11575318
    Abstract: Various embodiments relate to a voltage converter including a control unit configured for operating in a hysteretic control mode. A control unit may be configured to receive a PWM signal, a duty cycle signal, at least one reference voltage, a factor of an output voltage of the voltage converter, and a factor of an input voltage of the voltage converter. The control unit may also be configured to compare the at least one reference voltage to the factor of the output voltage and the factor of the input voltage. Further, the control unit may be configured to generate a first control signal mirroring the PWM signal in response to at least one of: the factor of the input voltage being greater than the at least one reference voltage and the factor of the output voltage being greater than the at least one reference voltage.

  • Patent number: 10871427
    Abstract: A biological liquid collection vessel is adapted to contain a biological liquid to be centrifuged. The collection vessel has a vessel body having an open upper end and a closed lower end, a continuous wall, a target area at the upper end, and a solids area at the lower end that is connected to the target area. The target area is extended in length. In some embodiments, a volume capacity of both of the target area and the solids area are configured so that a red blood cell portion of the centrifuged biological liquid (e.g., blood) is substantially contained in the solids area, and the serum or plasma portion of the centrifuged biological liquid is substantially contained in the target area. Methods of and systems using the liquid collection vessels are provided, as are other aspects.

  • Patent number: 10756627
    Abstract: A switch mode power supply (voltage converter) is adapted as a current-mode control buck regulator for different loading conditions. The voltage converter operates in a continuous conduction mode (CCM) during heavy load conditions using pulse width modulation (PWM). When a zero-current detector determines no inductor current during light load conditions (discontinuous conduction mode (DCM) region), the controller initiates adaptive duty control using pulse frequency modulation (PFM). Adaptive duty estimation circuitry provides controllable energy to charge the power inductor to maintain voltage accuracy and maximize efficiency when in the PFM mode. Using clock synchronization and a single control-loop, smooth transition between PFM, PWM, and bypass modes is automatically performed. Clock synchronization from a master oscillator provides a base for frequency division in different operation modes which gives controllable evenly distributed switching harmonics.

  • Patent number: 10110610
    Abstract: Methods and systems of the present disclosure provide techniques for dynamically assessing a permission of a user that one of modifies or adds at least one content change in a source environment. The methods may further assess the permission of the user when the at least one content change relates to role content data or functional content data. The permissions of the users may be evaluated based on rule data specific to the source environment or user assignment data relating to the source environment. In addition, the disclosure provides techniques for reporting the dynamic assessment to an administrator based on a triggering event.

  • Publication number: 20140100910
    Abstract: Systems and methods for defining and executing platform and language independent audit templates are disclosed. Each audit template can include a number of audit task templates. The audit task templates include general instructions for performing an audit task. Each audit task template can be instantiated as an audit task in an associated audit operation that includes organization or process specific information. Each audit task template and audit task can be linked with one or more business rules. Such business rules include translation logic for translating requirements of each audit task into a format expected by specific program, located in a central management system, invoked to operate on the required target business data. The business rules can also include translation data for interpreting the results returned from such programs. The audits operation or business rules can also include deficiency criteria, or alert conditions for initiating audit issues and remediation workflows.
