Abstract: A trans-illumination device includes at least first and second sets of LEDs of two or more different colors arranged in a light head placed against a patient's skin. The LEDs are mounted to a printed circuit board in the light head. An electronic control circuit is coupled to the light head by an electrical cable to selectively operate the LEDs in two or more user-selected modes, with the ability to adjust the relative intensities of the different colors to best suit the physiology of the patient. The light head may have a U-shape to surround an area of interest while providing ready access thereto. The light head may be used with a disposable, detachable cover having lenses for directing light from the LEDs into the patient's tissues.

Abstract: A pediatric tissue illuminator includes a semi-rigid lighting head removably connected to a powered base unit for illuminating an infant's tissues while stabilizing a limb for venipuncture. The lighting head includes a series of LEDs and is placed behind an infant's arm, thereby directing light therethrough for enhanced viewing. A printed circuit board in the lighting head routes electrical conductors to the LEDs. A translucent soft covering is disposed between the printed circuit board and the infant's body. The base unit includes a control circuit for varying the application of electrical power to the lighting head via an electrical cable. The arm board/light head is inexpensive enough to be disposable. Alternatively, a re-useable light head may be used with disposable semi-rigid housings.

Abstract: Disclosed is a digitally controlled multi-phase voltage regulator system providing regulated power to electronic components that have variable power requirements. Power is supplied by one or more power integrated circuits (IC) each having a high side power switch controlled by pulse width modulated signals and a low side power switch. The power IC senses voltage at the load and has an on-chip current mirror for generating a current that is a ratio of current delivered to the load. The power IC also has current limiting and on-chip temperature sensing components. The voltage and current information is digitized and provided to a control integrated circuit (IC). The control IC receives this digitized information as well as user provided parameters and, in the regulation mode of operation, provides digitized pulse width modulated control signals to the power IC. In an active transient response mode of operation, the control IC provides signals to turn either the high side switches or low side switches ON.

Abstract: A highly phased power regulation (converter) system having an improved control feature is provided. A controller, such as a digital signal processor or microprocessor, receives digital information from a plurality of power conversion blocks and transmits control commands in response to the information. The controller is able to change the mode of operation of the system and/or re-phase the power blocks to accommodate a dynamic load requirement, occasions of high transient response or detection of a fault. A compensation block within the controller is used to regulate the output voltage and provide stability to the system. In one embodiment, the controller is implemented as a PID compensator controller. In another embodiment, a microprocessor is able to receive feedback on its own operation thus providing enabling the controller to anticipate and predict conditions by analyzing precursor data.

Abstract: The present invention provides a power regulation system and method with high speed signal settling capabilities for providing rapid active transient response to a microelectronic device. An active transient response system includes a power supply configured to receive external and/or internal signals indicating the occurrence of transient load conditions and to respond to the transient load conditions based on one or more of these signals. The system may further include a transient suppressor configured for early detection of transients, assisting in transient suppression, and early signaling of transient activity to the power supply. The system provides rapid recovery to steady state operation from the active transient response mode by using a digital compensator to quickly modifying the duty cycle and provide a voltage offset proportional to the transient microprocessor load step. Recovery is further improved by current rephasing techniques.

Abstract: Currents flowing in the various channels within a voltage regulator module (VRM) are suitably converted to digital equivalents that can be processed to control each module in a modular power supply. Functions that may be digitally implemented include current balancing between channels, current sharing between various modules in a power supply, and/or the like. By monitoring the current provided on each channel within a module, for example, a controller can determine an average current for the channels, which in turn can be used to identify and compensate for over- or under-production in any particular channel. Active voltage positioning techniques and overload protection may also be implemented using digital techniques.
