    • An infusion catheter having a distal shaft with an infusion tube extending from a proximal end to a distal end of the distal shaft, and a proximal cannula with an inner dimension and a distal end attached to a proximal end of the distal shaft to define an opening between the inner diameter of the infusion tube and the inner dimension of the proximal cannula. Also, a guidewire tube disposed within the inner dimension and the distal shaft and extending from the proximal end of the proximal cannula to the distal end of the distal shaft. The inner diameter of the infusion tube, the opening, the exterior dimension of the guidewire tube and the inner dimension cooperate and define sufficient cross sectional sizes to allow a treatment agent to be infused between the proximal end of the proximal cannula and the region of interest.

    • A method and apparatus for accomplishing an OPC (optimal power calibration) at a test area secured in data recording area of a writable optical recording medium and detecting an optimal writing power appropriate to the test area, are discussed. According to an embodiment, the method searches for a marginal area adjacent to a data section recorded on an optical recording medium, records test data on the marginal area discovered in the searching step while changing a writing power; and reproduces the test data recorded on the marginal area and determining an optimal writing power based upon the characteristics of the reproduction signal.

    • A transmitter and a transmitting method in a code division multiplexing (CDM) wireless communication system are provided. The transmitter includes a DC offset unit, a Barker code generating unit, a multiplier, a unipolar code generating unit, a Kronecker product unit, and a modulator. The DC offset unit transforms digital transmitting data to bipolar data, and the Barker code generating unit generates a Barker code. The multiplier multiplies the bipolar data with the Barker code and outputting the multiplying result, and the unipolar code generating unit generates a predetermined unipolar code. The Kronecker product unit multiplies the multiplying result from the multiplier and the unipolar code based on the Kronecker product, and outputs the result thereof, and the modulator modulates the output of the Kronecker produce unit through the On-Off keying modulation scheme.
