  • Patent number: 9705904
    Abstract: As part of an analysis of the likelihood that a given input (e.g. a file, etc.) includes malicious code, a convolutional neural network can be used to review a sequence of chunks into which an input is divided to assess how best to navigate through the input and to classify parts of the input in a most optimal manner. At least some of the sequence of chunks can be further examined using a recurrent neural network in series with the convolutional neural network to determine how to progress through the sequence of chunks. A state of the at least some of the chunks examined using the recurrent neural network summarized to form an output indicative of the likelihood that the input includes malicious code. Methods, systems, and articles of manufacture are also described.

  • Patent number: 9699842
    Abstract: A complementary converter is a switch mode converter circuit that uses one pulse-width modulation (PWM) controller and one power MOSFET to run a two-stage power-factor-corrected (PFC) power supply. The two-stage power-factor-corrected power supply can include a power-factor-corrected boost converter, and a DC-to-DC converter (either step-up or step-down). The DC-to-DC converter can be, e.g., a Flyback, Forward, Cuk, or Buck Converter. The complementary converter circuit includes a voltage input section that takes a universal VAC input and rectifies the input. Then the PFC boost converter boosts the rectified half-cycle DC to a DC line at a higher voltage. The complementary converter circuit further includes an integrated circuit with the power-factor-correction and PWM switching capabilities to control the converters. The DC-to-DC converter brings the voltage down to an appropriate level for the final load (e.g., LEDs).

  • Publication number: 20170141954
    Abstract: A wireless access point (10) connected to a fixed telecommunications network (12) broadcasts codes relating to one or more network identities (100, 101) identifying availability of wireless connection to the access point, If connection to the telecommunications network (12) is lost, it suspends one of the identity codes (100) and replaces it with a special identity code for a network identity (102) configured to co-operate with a mobile terminal (53) equipped to recognise the special identity code and transmit a message over another communications link (6, 49) to alert a service centre (7) to the fault (13).

  • Publication number: 20160354767
    Abstract: The present invention relates to methods for producing metal-supported thin layer skeletal catalyst structures, to methods for producing catalyst support structures without separately applying an intermediate washcoat layer, and to novel catalyst compositions produced by these methods. Catalyst precursors may be interdiffused with the underlying metal support then activated to create catalytically active skeletal alloy surfaces. The resulting metal-anchored skeletal layers provide increased conversion per geometric area compared to conversions from other types of supported alloy catalysts of similar bulk compositions, and provide resistance to activity loss when used under severe on-stream conditions. Particular compositions of the metal-supported skeletal catalyst alloy structures can be used for conventional steam methane reforming to produce syngas from natural gas and steam, for hydrodeoxygenation of pyrolysis bio-oils, and for other metal-catalyzed reactions inter alia.

  • Publication number: 20160350532
    Abstract: Using a recurrent neural network (RNN) that has been trained to a satisfactory level of performance, highly discriminative features can be extracted by running a sample through the RNN, and then extracting a final hidden state hi, where i is the number of instructions of the sample. This resulting feature vector may then be concatenated with the other hand-engineered features, and a larger classifier may then be trained on hand-engineered as well as automatically determined features. Related apparatus, systems, techniques and articles are also described.
