    摘要: A switch-mode DC/DC converter and a linear low drop out (LDO) DC/DC regulator are connected in parallel to drive a single load. Both regulators share a common voltage reference, feedback network, input supply and output such that the regulated voltage is identical during each mode of operation. During heavy loads the switch-mode regulator is in operation and the linear regulator is disabled for the highest efficiency possible. Conversely at light loads the linear regulator is in operation with the switch-mode regulator disabled, also maximizing the efficiency. Each regulator senses load current to automatically transition between the appropriate voltage regulators at fixed load current levels. The presented invention also includes a make before break transition scheme of the voltage regulators to minimize the voltage transients.

    摘要: An electrical component is mounted on a carrier printed circuit board. A first header connector connects the carrier printed circuit board to a printed circuit board on one side of the electrical component. A second header connector connects the carrier printed circuit board to the printed circuit board on the opposite side of the electrical component. The carrier printed circuit board and the printed circuit board are connected so that the electrical component is sandwiched between the carrier printed circuit board and the printed circuit board. The carrier printed circuit board, the first header connector, and the second header connector protect the electrical component from impact and mechanical stress. The carrier printed circuit board redistributes the electrical connection of the electrical component.

    摘要: Systems and methods for accurate temperature modification of a patient, or selected regions thereof, including inducing hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. A temperature measurement scheme for obtaining body core temperature is provided, including methods of obtaining and analyzing temperature data to provide feedback to the control unit for use in controlling the heating and cooling of the heat exchange medium so as to heat or cool a patient to a desired target temperature.
