Abstract: The present disclosure provides methods for producing N-(fluorosulfonyl)azoles, sulfonyldiazoles, or related derivatives thereof, and the related products including N-(fluorosulfonyl)azoles, sulfonyldiazoles, and related derivatives thereof. For example, an N-(fluorosulfonyl)azole is obtained by reaction of sulfuryl fluoride with an azoles, an azolate salt, an N-silylazole, or a combination thereof. Symmetric and asymmetric sulfonyldiazoles are obtained by further reaction of such an N-(fluorosulfonyl)azole with azoles, azolate salts, or N-silylazoles. A sulfonyldiazole can be also produced by reacting sulfuryl fluoride with an azole, an N-silylazole, or a combination thereof in one pot.

Abstract: Methods for producing triflazoles or related derivatives thereof, and the resulting products are provided. For example, triflazoles can be prepared by reaction of trifluoromethanesulfonyl fluoride with an azole or azolate salt. Yields up to 78% are obtained. Triflazoles can be prepared by the reaction of a trifluoromethanesulfonyl fluoride with an N-silylazole in the presence of a basic catalyst. Yields up to 97% are obtained.

Abstract: Embodiments of the present disclosure pertain to extracting data from images using neural networks. In one embodiment, an image is fit to a predetermined bounding window. The image is then processed with a convolutional neural network to produce a three dimensional data cube. Slices of the cube are processed by an encoder RNN, and the results concatenated. The concatenated results are processed by an attention layer with input from a downstream decoder RNN. The attention layer output is provided to the decoder RNN to generate a probability array where values in the probability array correspond to particular characters in a character set. The maximum value is selected, and translated into an output character. In one embodiment, an amount may be extracted from an image of a receipt.

Abstract: Dimethylamine (Me2NH) is reacted with sulfuryl fluoride (SO2F2) to form at least a first phase comprising N-(fluorosulfonyl) dimethylamine (FSO2NMe2), tetramethylsulfamide (SO2(NMe2)2), or a combination thereof. A second phase, which may include dimethylamine hydrofluoride (Me2NH2F), may be also formed and separated from the first phase. FSO2NMe2 or SO2(NMe2)2 is then isolated from the first phase. For example, the first phase may be a liquid phase, and FSO2NMe2 and SO2(NMe2)2 are separated by distillation, optionally under reduced pressure.

Abstract: Secure and efficient methods and systems of providing multiple access interference constraints for frequency hopped spread spectrum communications are presented. The methods and systems leverage a cryptographic keystream generator and iterative indexing into shuffled lists to generate a constrained collision-free frequency hopping sequence. This flexible frequency hopping access (FFHA) can support varying hop frequency and bandwidth resources including secure operation for applications where the number of channels (hopping sequences) exceeds the number of hop frequency resources available.

Abstract: The present invention is directed to methods for preparing a fluorosulfonate ester or a salt thereof, through a reaction of a dissolved sulfonyl fluoride (RFSO2F) with alkoxide anion (RO?) optionally in the presence of an aprotic base (B), where RF is fluorine or a C1-C8 perfluoroalkyl group, and R is a primary alkyl or alkoxyalkyl. Alkoxide anion (RO?) can be generated from a precursor such as an alcohol or silyl ester.

Abstract: The present invention is directed to methods comprising adding ammonia, either as an ammonium salt or as a gas at pressures below 0.01 MPa, to a sulfuryl fluoride solution to form the anion of bis(fluorosulfonyl)amine under conditions well suited for large-scale production. The bis(fluorosulfonyl)amine so produced can be isolated by methods described in the prior art, or isolated as an organic ion pair, such as an alkylammonium solid salt, or as an ionic liquid.

Abstract: A wireless communication network is provided that includes a plurality of communication cells each defined by at least one communication coverage area and a plurality of access points each corresponding to a different one of the plurality of communication cells. Each access point is configured to communicate on a first frequency with at least one of (i) a subscriber in the at least one communication coverage area in a first communication cell and (ii) a subscriber in a second communication cell. Each access point is further configured to communicate on a second frequency with an access point in a third communication cell.
