20150349818 | Parallel connection method and device for multi-channel PD signals - A parallel connection method and a device for multi-channel partial discharge (PD) signals have input sources of pre-processed and amplified signals received by multiple PD sensors.

20150349913 | SYSTEM, DEVICE, AND METHOD FOR SECURING VOICE AUTHENTICATION AND END-TO-END SPEECH INTERACTION - A method, device, and system for secure end-to-end audio recognition is disclosed. A client device launches an application that connects with a server. The client device and server exchange cryptographic keys and establish a secure connection and a shared cryptographic key. The server transmits an encrypted audio prompt to the client device. The client device decrypts the encrypted audio prompt and stores the decrypted audio prompt in secure memory inaccessible to the operating system using an audio engine of the client device. The audio engine then retrieves the audio and renders it for the user through the speakers of the client device. The client device captures the user's audio response with a microphone and stores the audio response in the secure memory. The stored audio response is encrypted and transmitted to the server. | 2015-12-03 |
20150349914 | ANALOG RF MEMORY SYSTEM - An electronic analog memory system includes at least one analog programmable delay module configured to receive an input radio frequency pulse. The analog programmable delay module generates a time delayed output signal in response to applying at least one time delay to the input radio frequency pulse. A switching module is configured to selectively deliver the time delayed output signal to an output of the electronic analog memory system. The electronic analog memory system further includes an activity detector module configured to determine the amplitude of the input radio frequency pulse.

20150349915 | METHOD AND APPARATUS FOR GENERATING FRAMES FOR ERROR CORRECTION - A method and apparatus for generating frames to apply error correction to data including a plurality of consecutive data groups are provided. Upon receiving input of an n-th data group consisting of a plurality of priority groups with different priority levels, the number of first code rate frames, which is the number of frames in the n-th data group for which a first code rate is used, is calculated based on the number of first code rate bits calculated based on the ratio of the length of data in an (n−1)-th data group for which the first code rate is used. The number of second code rate frames, which is the number of frames in the n-th data group for which the second code rate is used, is calculated based on the number of second code rate bits calculated based on the number of first code rate bits. Frames for error correction are generated based on the number of first code rate frames and the number of second code rate frames. | 2015-12-03 |
