    Abstract: A charging device with boundary mode control is disclosed. The charging device includes a transformer, a power switch, a detection circuit and a pulse-width modulation (PWM) controller. The power switch is electrically connected to one end of a primary-side winding of the transformer. The detection circuit is electrically connected to the primary-side winding and the power switch. The detection circuit detects the resonance of the parasitic capacitance of the power switch, thereby generating a detection signal for boundary mode control. The PWM controller generates a pulse-width modulation signal for driving the power switch, and turns on the power switch according to the detection signal.

    Abstract: A FET device for operation at high voltages includes a substrate, a first well and a second well within the substrate that are doped with implants of a first type and second type, respectively. The first and second wells define a p-n junction. A field oxide layer within the second well defines a first surface region to receive a drain contact. A third well is located at least partially in the first well, includes doped implants of the second type, and is adapted to receive a source contact. As such, the third well defines a channel between itself and the second well within the first well. A gate is disposed over the channel. At least a first portion of the gate is disposed over the p-n junction, and includes doped implants of the first type. A number of permutations are allowed for doping the remainder of the gate.

    Abstract: A low-cost general method to perform subsalt velocity analysis is provided. For instances where sediment velocity structure is relatively simple, the method includes a single one-time redatuming to the base of salt, using existing prestack wave equation tools. For instances where the sediment velocity structure has a variable topography, the method includes multi-step redatuming to the base of salt. The method is designed to completely remove the salt-sediment overburden effects, and redatum the surface seismic data to a flat arbitrary subsalt datum, removing the complexity of the wavefield caused by the salt bodies. Once having obtained a simplified wavefield by stripping off the effects of the complex overburden, less expensive Kirchhoff imaging algorithms are employed for performing subsalt velocity model building.
