Abstract: A method is presented for tracking an ingestible device in a gastrointestinal tract of a subject. The method includes: measuring acceleration of the ingestible device as it traverses through the gastrointestinal tract, for example using an accelerometer disposed in the ingestible device; computing a metric from the acceleration measurements obtained by the accelerometer over a given period of time; and identifying a location in the gastrointestinal tract based in part on the metric.

Abstract: Methods, systems, and computer programs are presented for determining parameters of neural networks and selecting embedding dimensions for the feature fields. One method includes an operation for initializing parameters of a neural network and weights for embedding sizes for each feature associated with the neural network. The parameters of the neural network and the weights are iteratively optimized. Each optimization iteration comprises training the neural network with current parameters of the neural network to optimize a value of the weights, and training the neural network with current values of the weights to optimize the parameters of the neural network. Further, the method includes operations for selecting embedding sizes for the features based on the optimized values of the weights, and for training the neural network based on the selected embedding sizes for the features to obtain an estimator model. A prediction is generated utilizing the estimator model.

Abstract: A service request is received by a terminal device. First biometric authentication information of a user associated with the service request is collected. The first biometric authentication information is compated with preset biometric authentication information. When the comparison shows that the first biometric authentication information and the preset biometric authentication information are consistent, a pre-stored digital signature certificate private key is read. The service request is digitally signed according to the digital signature certificate private key. A biometric information verification message is generated and sent message to a server. The server is configured to read a pre-stored digital signature certificate public key corresponding to the digital signature certificate private key. Authentication result information is receiving from the server after the server verifies and signs the biometric information verification message according to the digital signature certificate public key.

Abstract: The present disclosure includes systems and methods for providing popups, including the following computer-implemented method. A trigger event is received that is generated by detection of a request for a presentation of a pop-up window. Based on the received trigger event, an activity pop-up component is launched that is configured to output the pop-up window, where a launch mode of the activity pop-up component is preconfigured as a single task mode. A determination is made whether the pop-up window output by the activity pop-up component is obscured by a pre-existing pop-up window. Upon determining that the pop-up window output by the activity pop-up component is obscured by the pre-existing pop-up window, the activity pop-up component is relaunched to trigger movement of the pop-up window to the top of an activity stack to force a non-obscured display of the pop-up window.
