Abstract: A method, in a power supply controller, of responding to an increase in current through a terminal of the power supply controller, is disclosed. The method includes regulating the terminal to a first voltage level and sensing a magnitude of a first current through the terminal while the controller is regulating the terminal to the first voltage level. The method also includes providing an initial response by the power supply controller in response to the magnitude of the first current exceeding a first threshold current level and then regulating the terminal to a second voltage level after the magnitude of the first current exceeds the first threshold current level. The magnitude of a second current through the terminal is sensed while the controller is regulating the terminal to the second voltage level and the controller determines a final response based on the magnitude of the second current.

Abstract: Compositions, kits and methods for promoting diabetic wound healing are based on the discovery that SDF-1α specifically upregulates expression of E-selectin in mature endothelial cells (EC), leading to an increase in EC-endothelial progenitor cell (EPC) adhesion and EPC homing. Methods for promoting healing of a wound in a diabetic subject include providing a therapeutically effective amount of a composition including E-selectin protein or a nucleic acid encoding E-selectin protein, and optionally, an agent that specifically upregulates E-selectin expression (e.g., SDF-1α). The methods can also include administering hyperbaric oxygen treatment to the subject. Administering the composition to the subject results in migration of bone marrow-derived progenitor cells to the wound, accelerated wound healing, and upregulation of E-selectin expression in the subject.

Abstract: An example controller for a power supply includes a drive signal generator and a compensation circuit. The drive signal generator is to be coupled to control switching of a switch included in the power supply to regulate an output voltage of the power supply in response to a sensed output voltage such that the output voltage of the power supply is greater than an input voltage of the power supply. The compensation circuit is coupled to the drive signal generator and is also coupled to output an offset current to adjust the sensed output voltage in response to the input voltage of the power supply.

Abstract: A method is disclosed to add functionality to a terminal of a high voltage integrated circuit without the penalty of additional high voltage circuitry. The benefit is that alternative modes of operation can be selected for testing, trimming parameters of the integrated circuit, or any other purpose without the cost of an additional terminal. In one embodiment, ordinary low voltage circuitry monitors the voltage on the terminal that normally is exposed to high voltage. The configuration of a simple voltage detector and an ordinary latch allows easy entry into the test and trimming mode when the integrated circuit is not in the intended application, but prohibits entry into the test and trimming mode when the integrated circuit operates in the intended application.
