The present disclosure provides a method in a base station of a radio network for antenna calibration of a first transceiver of the base station with respect to a second transceiver. The method comprises at least one of a first group and a second group of steps. The first group of steps comprises collecting a first group of amplitude and phase differences between a first calibration signal and each of a first and a fourth reception signals and between a second calibration signal and each of a second and a third reception signals. The first group of steps further comprises estimating, based on the first group of amplitude and phase differences, a signal response characteristic difference between a calibration reception chain of the first transceiver and a calibration reception chain of the second transceiver for reference antenna reception calibration of the first transceiver with respect to the second transceiver.

A mobile device includes a camera unit, a location unit, a transmitting unit, a self-defense mechanism, and a panic button. The camera unit location unit obtains at least one of image data and audio data, and the location unit obtains location data. The transmitting unit transmits at least one of the image data, the audio data, the location data, and specific information including owner identification information. The panic button is adapted to activate the camera, the location unit, the transmitting unit, and the self-defense mechanism.

Systems and techniques, including computer software, for retrieving information to a mobile device involve installing a data retrieval application on the mobile device. The data retrieval application includes instructions for presenting a structured data display on the mobile device, defining a structure of the structured data display, requesting selected hyperlinks included in the structured data display, and rendering markup language information received in response to the selected hyperlinks. A user request to retrieve data through the data retrieval application is received, and data is retrieved in response to the received user request. The retrieved data is displayed according to the structure of the structured data display, and a user can select a hyperlink in the displayed data to retrieve and render markup language information using the data retrieval application.

A radio communication equipment comprises an information card configured to record information on a service subscription provided by a network operator, a radio communicator configured to receive notification information of cancellation for the subscription by short message service (SMS) via radio communication, and a controller configured to notify that a subscription to a network operator corresponding to the information card has been cancelled, in response to the notification information received by the SMS.

A radio telescope array is provided for tracking radio sources that are essentially infinitely stable and resilient transmitters. The radio telescope array may be implemented with just a few antennas in different applications, such as an ionospheric density gradiometer or an imaging scintillometer. Data received at the radio telescope array may be utilized for various purposes, for example, to analyze ionospheric variations, study bursts of radio emission or monitor cosmic objects.

Three dimension (3D) model generation systems and methods are operable to generate 3D model data corresponding to images of a physical object of interest that are viewed in a presenting media content event. An exemplary embodiment receives a user request that is associated with an interest by the user to obtain a 3D model of a physical object of interest that is being shown in a scene of a currently presenting media content event. A plurality of video image frames are selected from the scene. Then, 3D model data of the physical object of interest is generated based on at least the selected video image frames of the scene.
