Patent number: 10565496Abstract: A method includes receiving N pairs of training examples and class labels therefor. Each pair includes a respective anchor example, and a respective non-anchor example capable of being a positive or a negative training example. The method further includes extracting features of the pairs by applying a DHCNN, and calculating, for each pair based on the features, a respective similarly measure between the respective anchor and no example. The method additionally includes calculating a similarity score based on the respective similarity measure for each pair. The score represents similarities between all anchor points and positive training examples in the pairs relative to similarities between all anchor points and negative training examples in the pairs. The method further includes maximizing the similarity score for the anchor example for each pair to pull together the training examples from a same class while pushing apart the training examples from different classes.Type: GrantFiled: December 20, 2016Date of Patent: February 18, 2020Assignee: NEC CorporationInventor: Kihyuk Sohn

Patent number: 10536136Abstract: The present invention relates broadly to a method of digitally filtering a signal, such as an audio signal, using a digital filter. The digital filter includes a plurality of neighbouring sample points broken into zones having different frequency content or frequency ranges. The zones adjacent one another may have neighbouring sample points in common. Generally each zone has at least same distinct frequencies compared with other zones. That is, the zones are roughly dependent on the frequency content. The invention in its preferred form involves combining values for two or more of the neighbouring sample points for select of the zones depending on its frequency content. The values are combined so as to provide a modified zone having substantially the same number of sample points as the select zone. The modified zones together provide a modified filter to be applied to the signal.Type: GrantFiled: April 1, 2015Date of Patent: January 14, 2020Inventor: Lachlan Paul Barratt

Patent number: 9934634Abstract: A system employing a plurality of brain/body-generated inputs to control multi-action operation includes a controllable device, that performs at least two actions via remote control, and a head-mounted user interface device. The UI device includes a user cranium-mounted frame, first and second sensors supported by the frame, a processor, and a transmitter. The first sensor includes an electrode for contacting the cranium when the frame is worn and adapted to receive a bioelectric signal from the cranium. The second sensor receives hands-free brain/body input from the user. The processor uses application software process input provided by the first and second sensors and generates different outputs, corresponding to different commands. The transmitter transmits signals, based on the different commands, to the controllable device to initiate the different actions performed by the device.Type: GrantFiled: September 20, 2016Date of Patent: April 3, 2018Assignee: Make Ideas, LLCInventors: Keith Alan Mullin, Christopher Taddei

Patent number: 9015090Abstract: Identifying a questionable network address from a network communication. In an embodiment, a network device receives an incoming or outgoing connection request, a web page, an email, or other network communication. An evaluation module evaluates the network communication for a corresponding network address, which may be for the source or destination of the network communication. The network address generally includes an IP address. The evaluation module determines one or more properties of the network communication, such as time of day, content type, directionality, or the like. The evaluation module then determines whether the properties match or are otherwise allowed based on properties specified in the white list in association with the IP address.Type: GrantFiled: August 14, 2013Date of Patent: April 21, 2015Inventor: Daniel Chien
