Abstract: A self oscillating power converter uses two MOSFET transistors connected across first and second primary windings. Each MOSFET is controlled using a gate control circuit located in a feedback path. Each gate control circuit is driven by a gate drive winding which is transformer coupled to a primary winding and which is phased with the primary winding such that regenerative feedback causes accelerated sequential turn-on and turn-off of the associated MOSFET transistor. Each feedback path includes a capacitor for charging in response to the voltage generated across the gate drive winding to initiate turn-on of the MOSFET transistor and a resistor for discharging the capacitor to initiate turn-off of the MOSFET transistor. The power converter can be configured as a push-pull converter in either a common-drain or common-source configuration. The power converter can also be configured such that at least one MOSFET transistor is capacitively coupled to a primary winding. Further, the power converter can be configured as either a full-bridge or a half-bridge converter.

Abstract: B-cell malignancies, such as the B-cell subtype of non-Hodgkin's lymphoma and chronic lymphocytic leukemia, are significant contributors to cancer mortality. The response of B-cell malignancies to various forms of treatment is mixed. Traditional methods of treating B-cell malignancies, including chemotherapy and radiotherapy, have limited utility due to toxic side effects. Immunotherapy with anti-CD20 antibodies have also provided limited success. The use of antibodies that bind with the CD22 or CD19 antigen, however, provides an effective means to treat B-cell malignancies such as indolent and aggressive forms of B-cell lymphomas, and acute and chronic forms of lymphatic leukemias. Moreover, immunotherapy with anti-CD22 and/or anti-CD19 antibodies requires comparatively low doses of antibody protein, and can be used effectively in multimodal therapies.

Abstract: A system and method is provided for integrating corneal topographic data and ocular wavefront data with primary ametropia measurements to create a soft contact lens design. Corneal topographic data is used to design a better fitting soft contact lens by achieving a contact lens back surface which is uniquely matched to a particular corneal topography, or which is an averaged shape based on the particular corneal topography. In the case of a uniquely matched contact lens back surface, the unique back surface design also corrects for the primary and higher order optical aberrations of the cornea. Additionally, ocular wavefront analysis is used to determine the total optical aberration present in the eye. The total optical aberration, less any corneal optical aberration corrected utilizing the contact lens back surface, is corrected via the contact lens front surface design. The contact lens front surface is further designed to take into account the conventional refractive prescription elements required for a particular eye. As a result, the lens produced exhibits an improved custom fit, optimal refractive error correction and vision.
