A drive circuit is provided for an OLED pixel display. The drive circuit is adapted for use with a reference voltage source. It includes a first transistor and an OLED. The output circuit of the first transistor is operably connected between the reference voltage source and the OLED. Transmission gate means responsive to a control signal are provided to transmit a data signal to the first transistor. Means are provided for controlling the first transistor in accordance with a time domain modulation signal to provide an average current to the OLED which is a function of the data signal.

A method for identifying seismic horizons in digitized seismic images includes deploying a swarm of agents at an initial position in a seismic image to be analyzed, where the swarm of agents includes picking agents that define a direction for the swarm and averaging agents that smooth the direction of the swarm, identifying a direction to follow in the seismic image for each picking agent, and advancing each picking agent in the identified direction, and averaging, by the averaging agents, the directions identified by the picking agents, wherein if an information concentration measured by a picking agent at a current time step is greater than a previous time step, the picking agent keeps a previous direction, otherwise the picking agent changes direction according to the average current state of the set of averaging agents within its neighborhood.

The invention discloses a line safety margin checking method, which relates to the technical field of electric power safety margin, and comprises the following steps of: determining an optimal load rate meeting power supply reliability and a network structure under the condition of remaining margin without considering load growth; calculating the line load growth rate according to the average load rate of the line decreased in recent years; according to the line load growth rate, calculating an optimal line load rate under the condition of considering the margin reserved by load growth; calculating an average current reference value of the next year according to the daily average current of the line in the last year and the optimal load rate of the line under the condition of considering the margin reserved by load increase; and the line safety margin is calculated according to the rated current-carrying capacity and the average current reference value of the next year, so that the line safety margin calculated by combining the optimal load rate of the line through the data of recent years is more accurate, and data support is provided for monitoring the running state of the line.
