摘要： The disclosure relates to technology for detecting and tracking eye gaze. An apparatus comprises a visible wavelength camera, an infrared (IR) camera, and one or more processors. The one or more processors are configured to generate a three-dimensional (3D) point cloud of a person's face from IR data captured from the IR camera, generate a two-dimensional image of the person's face from visible wavelength data captured from the visible wavelength camera, and detect a symmetry plane of the person's face based on the 3D point cloud and the two-dimensional image. The symmetry plane divides the 3D point cloud into two portions. The one or more processors are further configured to reconstruct the 3D point cloud based on the symmetry plane, and track eye gaze of the person's face based on the reconstructed 3D point cloud.

摘要： The disclosure relates to in-ear electronic devices. According to one aspect, the in-ear electronic device comprises a housing shaped to be inserted into an ear canal of a human, a set of electrodes configured to sense electrical signals when the housing is inserted into the ear canal, an antenna, a radio frequency (RF) transceiver, an audio transducer, and a control circuit. The control circuit is configured to provide an audio signal to the audio transducer based on an input RF signal received on the antenna, wherein the audio transducer plays the audio signal into the ear canal. The control circuit is configured to form an output signal based on one or more electrical signals from the set of electrodes. The control circuit is configured to passively backscatter the input RF signal on the antenna based on the output signal to wirelessly transmit the output signal.

摘要： This disclosure relates to recommendations made to users based on learned behavior patterns. User behavior data is collected and grouped according labels. The grouped user behavior data is labeled and used to train a machine learning model based on features and tasks associated with the classification. User behavior is then predicted by applying the trained machine learning model to the collected user behavior data, and a task is recommended to the user.

摘要： Collaborative local positioning techniques, such as could be used with smart phones, surveying equipment, or other mobile devices, are described. The techniques include independent techniques for distance measurement between devices, the relative positioning of devices, and an absolute orienting of the devices without use of fixed anchor points and through on-will participation of the devices to provide privacy. Distances between devices are determined by use of a sequence of positioning signals, such as a magnetic signal, each of which include an identifier of the transmitting device, the amplitude of the signal as transmitted, and the position of the signal within the sequence. The amplitude of the positioning signal as received can be compared to the amplitude as transmitted to obtain a distance.

摘要： A fault root cause analysis method and apparatus are provided. The method includes: obtaining a first alarm event set, where the first alarm event set includes a plurality of alarm events; for a first alarm event in the first alarm event set, extracting a feature vector of the first alarm event, where a part of or all features of the feature vector are used to represent a relationship between the first alarm event and another alarm event in the first alarm event set; and determining, based on the feature vector of the first alarm event, whether the first alarm event is a root cause alarm event. In this application, whether the first alarm event is the root cause alarm event is determined based on a feature vector of the relationship between the first alarm event and the another alarm event, and the accuracy of fault root cause identification is improved.
