Adaptive control for transition between multiple modulation modes in a switching power converter
ActiveUS20100225293A1Fast transitionLow output rippleEfficient power electronics conversionDc-dc conversionVoltage rangeSelf adaptive
In a switching power converter, PWM mode and PFM mode are separated into two independent control sections with the control voltage range in each control section determined independently. Each of the PWM and PFM modulation modes cannot operate continuously beyond its boundaries, thereby forming a control gap between the two control sections within which no continuous operation is allowed. In order to supply a load condition within the control gap, the power supply operates at the two boundaries of the control gap. Transition between PWM and PFM modes occurs fast, with low output voltage ripple. No limitation needs to be imposed on the control voltage range in each of the PWM and PFM control sections, because the control parameters in the PWM and PFM control sections need not be matched to one another, due to separation of the PWM and PFM modes by the control gap.

ActiveUS20080297520A1Fast transition timeHigh bandwidthDigital computer detailsCathode-ray tube indicatorsGraphicsTransceiver
Wireless communication of display information between an information handling system and display is supported by a direct connection between a graphics system of the information handling system and a transceiver of the information handling system. For example, the graphics system outputs pixel level display information through a cable directly to the transceiver. A converter on the transceiver converts the display information to network information, such as from a DisplayPort format to a PCI Express format, so the transceiver can send the display information through a wireless network, such as a personal area network, to the display. A display module located at the transceiver coordinates initiation of communication of display information from the graphics system to the display.

A system and method are provided for loading a sample into an analytical instrument using acoustic droplet ejection (“ADE”) in combination with a continuous flow sampling probe. An acoustic droplet ejector is used to eject small droplets of a fluid sample containing an analyte into the sampling tip of a continuous flow sampling probe, where the acoustically ejected droplet combines with a continuous, circulating flow stream of solvent within the flow probe. Fluid circulation within the probe transports the sample through a sample transport capillary to an outlet that directs the analyte away from the probe to an analytical instrument, e.g., a device that detects the presence, concentration quantity, and / or identity of the analyte. When the analytical instrument is a mass spectrometer or other type of device requiring the analyte to be in ionized form, the exiting droplets pass through an ionization region, e.g., an electrospray ion source, prior to entering the mass spectrometer or other analytical instrument. The method employs active flow control and enables real-time kinetic measurements.
