摘要： A heat dissipation device includes a base, a heat-dissipation portion attached to the base, at least one heat pipe connecting the base and the heat-dissipation portion and a fan directly secured to the heat-dissipation portion. The heat-dissipation portion comprises a square, tubular housing having opposite front and rear end portions opening to surroundings and a plurality of fins extending inclinedly and inwardly from an inner circumferential periphery of the housing. The housing of the heat-dissipation portion is employed as a fan duct to guide an airflow generated by the fan through the fins; the inclined orientation of the fins facilitates the airflow to flow toward the inner circumferential periphery of the housing and lower parts of the fins adjacent the inner circumferential periphery, whereby the airflow can effectively take heat away from the heat-dissipation portion.

摘要： An advertising server allocates advertising impressions to meet advertisers' demands for opportunities to run advertising, for example ad content inserted into Web pages for payment. Supplies of advertising impressions are paired by their characteristics with demands that the supplies could meet. For paired eligible supplies and demands, an ideal allocation is determined, between zero and a maximum. The ideal allocations for all pairs are the coordinates of a utopia point in multidimensional space, although meeting all these ideals is likely to be impossible because of practical constraints. Using optional weighting, candidate allocations are tested or compared. Each candidate allocation produces coordinates in the multidimensional space. The candidate allocations are compared, based on the relative proximity of their coordinates to the potentially-impossible utopia point in multidimensional space. A ranking is stored or the selected allocation is executed, under control of a programmed processor.

摘要： An advertising distribution system mediates and distributes advertising opportunities, especially insertions of ads on web pages, according to advertisers' representative targeting profiles. The number and characteristics of future ad impressions is forecast. A portion is allocated to guaranteed-delivery advertiser contracts and the remainder is offered on a spot market. A division between guaranteed and spot market allocations is sought to maximize revenue, taking into account a value associated with meeting the advertisers' representative profiles. The value of representativeness can be inferred from the marginal revenue of a spot market sale, and optionally weighted. The guaranteed and spot market revenues for all possible efficient allocations produces a curve. An operating point on the curve is determined by selecting a weighting factor or selecting a proportion of total revenue that shall be attributable to representativeness.

摘要： A controller IC adjusts the on time and cycle time of current flowing through the primary inductor of a flyback converter to generate a constant output current and constant output voltage. A desired output current limit is achieved even with an inductor whose inductance varies from the stated magnitude. A transconductance current is generated from a voltage across an emitter resistor and is then integrated to generate an integrated-current voltage. An inductor switch is turned on by an oscillator signal and turned off at the earlier of when the integrated-current voltage reaches a charge limit voltage during constant current mode or when the emitter resistor voltage reaches an error voltage during constant voltage mode. Current is output independently of the primary inductance by varying the current limit voltage inversely proportionally to the input voltage and by adjusting the cycle time so that it varies inversely proportionally to the output voltage.

摘要： A self-oscillating flyback converter includes a controller integrated circuit housed in a 3-pin package. A switch control terminal is coupled to the base of an inductor switch that controls the current through a primary inductor of the converter. The controller IC adjusts the on time of the switch such that output current remains constant in constant current mode and output voltage remains constant in constant voltage mode. A signal received on a switch control terminal turns the switch off and provides an indication of the output current when the switch is on. A signal received on a feedback terminal powers the controller IC and provides an indication of the output voltage when the switch is off. The controller IC is grounded through a ground terminal. The flyback converter transitions from critical conduction mode to discontinuous conduction mode at light loads to prevent its efficiency from deteriorating at high switching frequencies.

摘要： Various technologies for removing shoulder-bed effects from measurements of an earth formation made in a wellbore. In one implementation, a methodology for removing the shoulder-bed effects includes receiving the measurements and constructing a layered model of the earth formation. Each layer has a set of parameters corresponding to one or more types of the received measurements ascribed to each layer such that the set of parameters define a parameter space for the layered model. The methodology may further include dividing the parameter space into subspaces based on relationships among the parameters, selecting from the subspaces one or more starting points, minimizing a cost function using the one or more starting points to generate one or more candidate solutions having the shoulder-bed effects removed and selecting a final solution from the one or more candidate solutions.
