System and apparatus for internet traffic inspection via localized DNS caching
An approach is proposed to support Internet traffic inspection to detect and prevent access to blocked websites or resources. First, access requests initiated by users to websites hosted on servers over a network are intercepted by an inspection agent, which identifies and caches a pair of the domain/host name of each website and its corresponding IP address on the Internet to a localized DNS cache. When a newly intercepted access request identifies the website by its IP address only without specifying its domain/host name, the inspection agent looks up the domain name by its IP address from the DNS cache. If no domain name is found, the inspection agent redirects the access request to a proxy server instead of forwarding it to the server hosting the website for further inspection. The proxy server then inspects the IP address to determine if it is a legitimate website or not. |

Skewed MIMO antenna array for use in automotive imaging radar
A novel and useful system and method of constructing a skewed or staggered multiple input multiple output (MIMO) antenna array system for automotive radar having high azimuth and elevation angular resolution and accuracy that provides increased effective aperture while using a low number of TX and RX elements. Improved element separation is achieved by distancing (i.e. staggering or skewing) RX rows and TX columns by using row and column circular shifts along their major axis. Due to the physical size of antenna elements, it is not physically possible to place the rows and columns in the full array symmetric RX-TX pattern without creating a gap in the center of the virtual array. This array reduces the overall size of the antenna achieving a compact size and low side lobe level (SLL). In addition, to minimize the resulting RX saturation of elements physically close to TX elements, the system blanks (i.e. zeros) the data for those elements. The rows of the transmit columns may also be staggered, either symmetrically or asymmetrically depending on the skewing factor. |

Method of direct bonding semiconductor components
A method of bonding semiconductor components is described. In one aspect a first component, for example a semiconductor die, is bonded to a second component, for example a semiconductor wafer or another die, by direct metal-metal bonds between metal bumps on one component and corresponding bumps or contact pads on the other component. In addition, a number of solder bumps are provided on one of the components, and corresponding contact areas on the other component, and fast solidified solder connections are established between the solder bumps and the corresponding contact areas, without realizing the metal-metal bonds.

Audio source separation for audio devices
Implementations of the subject technology provide systems and methods for providing audio source separation for audio input, such as for audio devices having limited power and/or computing resources. The subject technology may allow an audio device to leverage processing and/or power resources of a companion device that is communicatively coupled to the audio device. The companion device may identify a noise condition of the audio device, select a source separation model based on the noise condition, and provide the source separation model to the audio device. In this way, the audio device can provide audio source separation functionality using a relatively small footprint source separation model that is specific to the noise condition in which the audio device is operated. |

Systems and methods for filtering unwanted sounds from a conference call using voice synthesis
To filter unwanted sounds from a conference call, a first voice signal is captured by a first device during a conference call and converted into corresponding text, which is then analyzed to determine that a first portion of the text was spoken by a first user and a second portion of the text was spoken by a second user. If the first user is relevant to the conference call while the second user is not, the first voice signal is prevented from being transmitted into the conference call, the first portion of text is converted into a second voice signal using a voice profile of the first user to synthesize the voice of the first user, and the second voice signal is then transmitted into the conference call. The second portion of text is not converted into a voice signal, as the second user is determined not to be relevant. |

Reducing the need for manual start/end-pointing and trigger phrases
Systems and processes for selectively processing and responding to a spoken user input are provided. In one example, audio input containing a spoken user input can be received at a user device. The spoken user input can be identified from the audio input by identifying start and end-points of the spoken user input. It can be determined whether or not the spoken user input was intended for a virtual assistant based on contextual information. The determination can be made using a rule-based system or a probabilistic system. If it is determined that the spoken user input was intended for the virtual assistant, the spoken user input can be processed and an appropriate response can be generated. If it is instead determined that the spoken user input was not intended for the virtual assistant, the spoken user input can be ignored and/or no response can be generated. |
