Patent number: 9541667Abstract: Systems and methods for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate “ghosted” radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.Type: GrantFiled: August 23, 2016Date of Patent: January 10, 2017Assignee: United Parcel Service of America, Inc.Inventors: Wendie Patricia Hayler, Mark Rutherford, Marcus A. Jones, Anthony David Kirk, Gilbert Walter Vanorder, III, Roy Douglas Hudson, Paul Mason, James Termini

Patent number: 9190854Abstract: A power management unit accurately measures and controls charging current. The power management unit may be implemented more efficiently than prior designs, leading to cost savings in the implementation of the power management unit as well as in the implementation of the device that incorporates the power management unit. The power management unit incorporates a model of an external charge control device (e.g., a transistor) and uses that model in a way that allows the power management unit to eliminate external device pins and other circuitry.Type: GrantFiled: June 19, 2012Date of Patent: November 17, 2015Assignee: Broadcom CorporationInventors: Kerry Thompson, John McNitt, Mark Rutherford

Patent number: 8106707Abstract: Embodiments of the present invention include systems and methods for generating a curvature compensated bandgap voltage reference. In an embodiment, a curvature compensated bandgap reference voltage is achieved by injecting a temperature dependent current at different points in the bandgap reference voltage circuit. In an embodiment, the temperature dependent current is injected in the proportional to absolute temperature (PTAT) and complementary to absolute temperature (CTAT) current generation block of the bandgap circuit. Alternatively, or additionally, the temperature dependent current is injected at the output stage of the bandgap circuit. In an embodiment, the temperature dependent current is a linear piecewise continuous function of temperature. In another embodiment, the temperature dependent current has opposite dependence on temperature to that of the bandgap voltage reference before curvature compensation.Type: GrantFiled: July 7, 2009Date of Patent: January 31, 2012Assignee: Broadcom CorporationInventors: Vipul Katyal, Mark Rutherford

Patent number: 7668239Abstract: An improved method and apparatus for transmitting digital signals in a communications channel by compensating for distortions due to attenuation of high frequency components suffered by the digital signals. In a preferred embodiment, the digital signals are pulses and the compensation is performed at the transmitter without the need for an emphasis driver, by widening the pulses to compensate for the distortion in the channel that results in narrowing of the pulses incurred in the channel. The resulting pulse train is pre-compensated for the distortions caused by the communications channel. The amount of pre-compensation can be determined statically or dynamically.Type: GrantFiled: September 19, 2006Date of Patent: February 23, 2010Assignee: LSI CorporationInventors: Mark J. Marlett, Mark Rutherford, Peter Windler

Patent number: 7542508Abstract: A continuous-time domain Decision Feedback Equalizer (DFE) for use in a serial communication channel comprises in one embodiment a summer, a decision circuit, a capture flip-flop (FF) and an N-th order active filter. The DFE and its active filter operate in continuous time to give improved performance over a discrete-time DFE. In one embodiment involving a first-order active filter, the capture FF is outside the continuous-time negative feedback loop of the DFE and involves a differential signal amplifier. In another embodiment, the capture flip-flop is inside the DFE loop, and in a third embodiment the decision circuit comprises a comparator.Type: GrantFiled: April 21, 2005Date of Patent: June 2, 2009Assignee: LSI Logic CorporationInventors: Mark J Marlett, Mark Rutherford
