Abstract: A switching converter has an input terminal, an output terminal, a switching circuit, a flying capacitor, and a pre-charge circuit. The input terminal receives an input voltage, the output terminal provides an output voltage. The switching circuit has a plurality of switch devices. The flying capacitor is coupled between at least two of the plurality of switch devices. The pre-charge circuit charges the flying capacitor via partially turning on a pre-charge switch during start-up of the switching converter. A first terminal of the pre-charge switch is coupled to the input terminal. A voltage at a second terminal of the pre-charge switch is controlled to follow a voltage at a control terminal of the pre-charge switch, and a voltage across the flying capacitor is controlled to increase when the input voltage increases.

Abstract: Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.

Abstract: A retractor/protector suitable for use in a surgical incision or a natural orifice comprises a longitudinal axis defining an instrument access channel extending from a proximal end to a distal end; a flexible outer ring; an inner ring; a flexible sheath extending between the outer ring and the inner ring; and at least one rigid segment adapted to attach to the flexible outer ring to thereby increase the rigidity of the outer ring. Embodiments of the retractor/protector are described that have interlocking and non-interlocking rigid segments. Embodiments are also described that have bases that insert into or under the flexible outer ring in addition to or in lieu of rigid segments to increase rigidity and/or provide support for a detachable cap.

Abstract: A protection unit, including a power switching device, with a mechanical switch. To improve the multipurpose nature of the power switching while making lockout easier and more reliable, provision is made for the power switching device to include an electrical actuator actuating the mechanical switch and being controlled by an electronic control unit, which is itself powered via an auxiliary switching device. A lockout system with a lock is provided, which, in a lockout configuration, mechanically keeps the mechanical switch and the auxiliary switching device in an isolation configuration, and, in operating configuration, allows the mechanical switch and the auxiliary switching device to move between the conduction configuration and the isolation configuration.

Abstract: A visual search system facilitates retrieval of provenance information using a machine learning model to generate content fingerprints that are invariant to benign transformations while being sensitive to manipulations. The machine learning model is trained on a training image dataset that includes original images, benign transformed variants of the original images, and manipulated variants of the original images. A loss function is used to train the machine learning model to minimize distances in an embedding space between benign transformed variants and their corresponding original images and increase distances between the manipulated variants and their corresponding original images.

Abstract: A fluidic coolant system for a fuel cell stack that includes a fluidic pump, a heat exchanger, and an ion exchange filter housing assembly is described. A fluidic outlet of the heat exchanger is fluidly coupled to the fluidic pump, and a fluidic inlet of the heat exchanger is fluidly coupled to the fuel cell stack. The fluidic pump is arranged to supply coolant from the heat exchanger to the fuel cell stack and the ion exchange filter housing assembly.
