    摘要: A power supply for an LED lamp has a set of coupled coils, primary-side power circuitry including a converter power switch for conducting input power, and secondary-side power circuitry including a dimming power switch. Power control circuitry includes converter control circuitry which generates a converter control signal for the converter power switch to maintain a desired undimmed level of lamp current at a normal operating value of a lamp voltage. Dimming control circuitry generates a dimming control signal for the dimming power switch to pulse-width modulate the lamp current at a duty cycle corresponding to a desired dimming. Operation of the converter control circuitry is modified during dimming to prevent an automatic increase of the lamp voltage in response to a decrease in lamp current, avoiding undesirable overshooting of the lamp current and providing more accurate and effective control over dimming operation.

    摘要: Methods and devices for mechanical and/or chemical-mechanical planarization of semiconductor wafers, field emission displays and other microelectronic substrate assemblies. One method of planarizing a microelectronic substrate assembly in accordance with the invention includes pressing a substrate assembly against a planarizing surface of a polishing pad at a pad/substrate interface defined by a surface area of the substrate assembly contacting the planarizing surface. The method continues by moving the substrate assembly and/or the polishing pad with respect to the other to rub at least one of the substrate assembly and the planarizing surface against the other at a relative velocity. As the substrate assembly and polishing pad rub against each other, a parameter indicative of drag force between the substrate assembly and the polishing pad is measured or sensed at periodic intervals. The drag force parameter, for example, can be lateral displacement or lateral forces between a first component coupled to one of the substrate assembly or the polishing pad and a second component in either a carrier assembly holding the substrate assembly or a table supporting the polishing pad. The drag force parameter can be measured along a lateral axis to produce a waveform having minimum and maximum peaks relative to minimum and maximum peak drag forces between the substrate assembly and the polishing pad along the axis. The maximum peak drag forces or the difference of the minimum and maximum peak drag forces are processed to generate a force-time relationship. The status of a parameter, such as the onset of planarity or the endpoint of the process, is then estimated by analyzing the force-time relationship.

    摘要: A method of visualizing network data includes parsing a collection of packets in accordance with a set of categories related to characteristics of the collection of packets, the categories including listings of categorical elements, wherein at least some of the categorical elements are selectable by a user. When a categorical element is selected by a user, the collection of packets is filtered in accordance with the selected categorical element. Alongside each categorical element is a selectable count value that is indicative of the number of discrete communications sessions in which an associated categorical element is present in the collection of packets. When the count value is selected, a session view or views is/are created for each respective session, with content payload available for review and viewing.

    摘要: An apparatus, program product and method improve management of available computing resources by adjusting use of the resource over a first interval according to actual use of the resource during a second interval. This feature enables a computing resource to exceed its normal limits during the first interval of operation. Use during the second interval may be limited to balance out the burst, or excessive resource usage of the first interval.

    摘要: A method and apparatus for conditioning and monitoring a planarizing medium used for planarizing a microelectronic substrate. In one embodiment, the apparatus can include a conditioning body having a conditioning surface that engages a planarizing surface of the planarizing medium and is movable relative to the planarizing medium. A force sensor is coupled to the conditioning body to detect a frictional force imparted to the conditioning body by the planarizing medium when the conditioning body and the planarizing medium are moved relative to each other. The apparatus can further include a feedback device that controls the motion, position, or force between the conditioning body and the planarizing medium to control the conditioning of the planarizing medium.
