Abstract: A duct can be configured to receive a denuding gas flow. A solid denuding surface that is connected to a drive system can be configured to move the solid denuding surface within the duct while the solid denuding surface is continuously concentrating one or more gas-phase species from the denuding gas flow on the denuding surface. Also, a denuding gas flow can be passed along a denuding surface to concentrate one or more gas phase species from the denuding gas flow onto the denuding surface with a diffusion denuding action. The denuding surface can be moved while continuing to concentrate the one or more gas phase species from the denuding gas flow onto the denuding surface.

The controller is configured to determine a target pressure for the accumulator based upon a condition of the refrigerant, obtain a current pressure in the accumulator from the pressure transducer, and to operate the recovery valve based upon the accumulator target pressure to control flow of refrigerant from the air conditioning system to the accumulator based upon the obtained current pressure and the determined target pressure for the accumulator.

Abstract: A method for predicting a canonical form for an input text sequence includes predicting the canonical form with a neural network model. The model includes an encoder, which generates a first representation of the input text sequence based on a representation of n-grams in the text sequence and a second representation of the input text sequence generated by a first neural network. The model also includes a decoder which sequentially predicts terms of the canonical form based on the first and second representations and a predicted prefix of the canonical form. The canonical form can be used, for example, to query a knowledge base or to generate a next utterance in a discourse.

Abstract: The present invention relates to a USB port locking device comprised of a USB locking dongle that locks into a USB port and an electronic key that unlocks the USB dongle. The USB locking dongle can be manually locked into a computer even if the computer is not receiving power. The USB locking dongle contains one or more protruding barbs that engage the female connector on a USB port physically blocking access to the port. The USB locking dongle can be safely removed when a programmed electronic key is positioned along one or more key terminals located on the USB locking dongle opposite the protruding barbs. The electronic key is a specially programmed memory device such as an iButton® that can be programmed to unlock a specific USB locking dongle or set of USB locking dongles.
